== | ==Dear Mr. Kiesling:== | ||
This letter is in response to your April 11, 2008 request for a jurisdictional determination onthe proposed project site for the construction of Units 3 & 4. The 1406.5-acre project site islocated on Farm-to-Market 521, approximately 8 miles west of Wadsworth, Matagorda County,Texas.Based on the review of the information associated with this request, we determined that therevised delineation map dated May 13, 2009 (enclosed) is a reasonable depiction of theapproximate locations of the aquatic resources with the tract. Computation ofjurisdiction madeon the basis of this preliminary jurisdictional determination will treat all waters, includingwetlands, on the 1406.5-acre tract as jurisdictional water of the United States. As such allaquatic resources, including 17.6 acres of wetlands and 24,639 linear feet of non-wetland watersare subject to Section 404 of the Clean Water Act and will require a Department of the Armypermit prior to the discharge of any dredged and/or fill material into these aquatic resources.Wetlands were identified on the tract using the 1987 Corps of Engineers Wetland DelineationManual which requires that under normal conditions wetlands exhibit wetland hydrology, hydricsoils, and hydrophytic vegetation.This determination has been conducted to identify the limits of the Corps' Clean Water Actjurisdiction for the particular site identified in this request. This determination may not be validfor the wetland conservation provisions of the Food Security Act of 1985, as amended. If you oryour tenant are USDA program participants, or anticipate participation in USDA programs, youshould request a certified wetland determination from the local office of the Natural ResourcesConservation Service prior to starting work. | |||
This preliminary jurisdictional determination is valid for 5 years from the date of this letter,unless new information warrants a revision prior to the expiration date. An approvedjurisdictional determination can be requested at any time. If you have any questions concerningthis matter, please reference file number SWG-2007-786 and contact Mr. Nicholas Laskowski atthe letterhead address or by telephone at 409-766-6381.Sincerely,Ke yy JaynsýýChief, Compliance SectionEnclosuresCc:U.S. Regulatory Commissionc/o Jessie Muir M/S T6-D3211555 Rockville PikeRockville, MD 20852 eV K~ca~ MII.gWd.-Waters (24,639.1 Linear Feet)EJ Wetlands (17.6 Acres)-]- Project Review Area (1406.5 Acres)=reliminary Jurisdictional DeterminationSouth Texas Project Units 3 & 4Matagorda County, TXW#1C fSWG-2007-786May 13, 20090 750 1,500 3.000P"4Cbo, NADI 193 SU"PUMJt.,.

Land Use Information for NRC Audit BinderAttachments: IEEE516.PDF; Original TreeSpec 97 05 Update with 11-15-05 revisions.docFriends,I received a request to forward to you information regarding Austin Energy (AE) Transmission ROWvegetation management on AE circuit 3123 and 3124 from the STNP Corridor at Danevang to Holmansubstation near La Grange. I hope the following information meets your needs." Austin Energy (AE) last performed ROW vegetation management in 2006 with extensive ROWdearing of brush and trees in the 100 foot ROW." Austin Energy is scheduled to perform vegetation maintenance on our four-year cycle, scheduledmaintenance this year, 2010 We are scheduled to begin field work on this ROW sometime inMarch, 2010* AE has completed our property ownership research and we are beginning our field patrols of theROW to assess vegetation conditions. Preliminary findings are that the ROW vegetationconditions are still very good, with good clearances and access." AE has an aggressive and thorough vegetation management program utilizing herbicideapplications, tree removals and mowing to control vegetation to prevent outages and maintainfacility access." AE Forestry Transmission Program is managed according to AE Tree Pruning and Line ClearanceSpecifications (attached). The methods of ROW maintenance that more direct our practices onthis ROW are outlined on page 4, item B of these specifications. This is paraphrased as "anyvegetation in the AE right-of-way that has the potential to grow into the clearance zone (20 feetminimum clearance near poles or structures and 25 feet at mid-span) of the transmissionconductors, should be targeted for removal... As right of way conditions allow, the right of waymay be kept clear of woody vegetation by mowing or other appropriate methods." (specificallyherbicide applications)." AE's specifies removal of trees that have the potential of growing into the clearance zonesurrounding the conductors, which is a minimum of 20 to 25 feet; and in most cases much moreclearance distance is achieved; which allows for four to five years of above-average tree growth.These distances are in addition to the 9.4 feet minimum distance for 345kV from the IEEE 5162003 Clearances (table attached)." AE Transmission Construction and Maintenance personnel patrol this transmission ROW twice ayear and report any vegetation concerns to AE Transmission Forestry Section for immediateattention for vegetation maintenance.Please let me know if this is the appropriate information you need. If you require any additionalsupporting information, please don't hesitate to contact me via e-mail with the specifics needed, or call meat one of the phone numbers given below.Thank you,Carl SchattenbergUtility ForesterAustin Energy(512) 322-6931 (Office)(512) 801-4997 (Cell)1/7/20 10 TER-4.

/4-- STPL_- 446AUSTIN ENERGYTREE PRUNING AND LINE CLEARANCE SPECIFICATIONSINTRODUCTIONThese Tree Pruning Specifications and Requirements, together with the American National StandardsInstitute ANSI A300, "Standard for Tree Care Operations" (as approved May 22, 2001, or subsequentrevision), shall govern all pruning and/or removal of any plant or tree growth interfering with the safeoperation of any City of Austin Energy (AE) facility. Where any discrepancy or contradiction existsbetween this contract document and the ANSI standard, the requirements of the contract document shallprevail.The primary goal for the line clearance tree pruning program is to maintain a safe and reliable electricaltransmission and distribution system. These specifications and requirements prescribe arboriculturalstandards to ensure consistent tree pruning practices, and efficient, economical line clearancemaintenance. They shall provide a basis for determining whether tree pruning is necessary orappropriate, and shall dictate the arboricultural methods to be adhered to in the performance of the workactivity described in this document.The AE is obliged and committed to compliance with the terms and conditions of City of Austin GeneralDevelopment Permit No. GP-05-0000.AEU, and any subsequent extension or renewal. The Vendor shallbe familiar with these terms and conditions, and will ensure that no violations occur as a result of theVendor's actions.All tree work shall conform to approved principles and techniques of modern arboriculture. Proper lineclearance tree pruning shall direct tree growth away from electrical conductors and facilities, extendpruning cycles, and reduce the overall amount of future pruning work required. The AE shall determinethe appropriate distances between all plant or tree growth and electrical facilities. Because of thedifficulty in developing line clearance tree pruning policies which would cover all circumstances, the AEreserves the right to assess, on a case-by-case basis, any special situations where the strict applicationof these specifications and requirements might be impractical or inappropriate.I. PRUNING SPECIFICATIONSThe following specifications shall apply to all tree pruning unless otherwise specified herein. For thepurpose of this line clearance tree pruning contract, a tree shall be considered to be a self-supportingwoody perennial plant, having a trunk diameter of no less than two inches (2") at maturity, measured atfour and one-half (4-1/2) feet (Qiameter at Breast Height, or DBH), with one (1) or more branchesdeveloping from the stem or trunk. Plants containing multiple trunks or stems, each of which exceeds twoinches (2") in diameter (DBH), will be considered to be one (1) tree when those stems originate from acommon root crown, or are less than six inches (6") apart.A) The most important technique in pruning a tree is the collar cut. This term refers to the final pruningcut to remove a limb just outside the raised portion (branch collar) of the branch junction with thetrunk or another limb. A proper collar cut will minimize the exposed surface area of the cut surface.All limb or branch removals shall be performed using the collar cut method.B) When removing a lateral branch at its point of origin on the trunk or parent limb, the final cut shall bemade in branch tissue close to the trunk or parent limb, without cutting into the branch bark ridge orcollar, or leaving a stub. (ANSI A300 Standard 5.3.2 and 5.3.3).C) When removing a dead branch, the final cut shall be made just outside the collar of live tissue. If thecollar has grown out along the branch stub, only the dead stub shall be removed. The live collar shallbe left intact and uninjured. (ANSI A300 Standard, 5.3.5).D) No stub and/or flush cuts shall be left on the trunk or supporting branch unless specifically requestedby the property owner and specifically approved by the AE, prior to the removal of branch or limb.11/07/05 1 Specifications and GuidelinesOriginal TreeSpec 97 05 Update.doc AUSTIN ENERGYTREE PRUNING AND LINE CLEARANCE SPECIFICATIONSE) Old stubs from prior stub cuts that have re-sprouted and re-grown into the electrical conductor cleararea shall be removed to the branch collar of the stubbed-off limb, or may be pruned to a lateral limb,behind the stub, large enough to assume the terminal role, consistent with these pruningspecifications and requirements.F) The three-cut method should be used in order to prevent ripping or peeling of the bark on the trunk orparent stem from which the limb is removed.G) When a leader, dominate or co-dominate stem is to be removed, it shall be removed back to a laterallimb or branch no less than one-third (1/3) of the diameter of the portion being removed.H) When removal of an entire lateral limb back to the branch collar on the parent stem would removeexcessive branch tissue and foliage, and is not necessary to obtain the required line clearance, theleader of a lateral limb may be pruned to a lateral limb large enough to assume the terminal role. Inmaking a thinning cut in this instance, the final cut shall be beyond the branch bark ridge of thecrotch.I) All final lateral pruning shall be concluded at a branch collar on the supporting branches or trunksgrowing away from the electrical facility, so that the growth of the tree is directed away from electricalfacilities (directional pruning).J) Directional pruning is used to redirect side growth away from the electrical facilities. Limbs growingtowards the facilities are removed to appropriate limbs or trunk to train the tree away from theelectrical facilities.K) Drop crotch pruning is used to reduce the height of a tree by removing dominant or co-dominantstems in the center of the crown of the tree and direct growth away from the electric lines overhead.This method of line clearance pruning is most often used when the conductors are involved with thecenter of the tree crown. Limbs should be cut at the branch bark ridge, consistent with properarboricultural techniques, as detailed in B) above.L) All tree pruning wounds and other wounds caused by AE operations on oak trees shall be treatedpromptly with a thin but complete covering of an approved non-phytotoxic tree wound dressing.Wounds on oaks shall be treated before moving to another part of the tree, and prior to descendingthe tree. All oak stumps shall be painted with a tree wound dressing, as required on all oak wounds.No other tree species shall be painted unless specifically requested by the property owner, ordirected by the AE. (ANSI A300 Standard, 5.4.1).M) Rips and peels are not acceptable and shall be avoided, but if they occur, tree wound dressing maybe applied, as a cosmetic treatment only. Tree wound dressing may be applied as a cosmetictreatment on large wounds.N) To help prevent the spread of various types of tree diseases, all cutting tools (hand and powered)shall be surface disinfected with a seventy percent (70%) or higher solution of alcohol and water.Other disinfectants, such as Lysol and 50% chlorine bleach (sodium hypochlorite) and water solutionmay be substituted. Disinfectants shall be applied prior to commencing any pruning on the job site,and immediately after pruning oaks suspected to be infected with oak wilt in a designated diseasedarea.11/07/05 2 Specifications and GuidelinesOriginal TreeSpec 97 05 Update.doc AUSTIN ENERGYTREE PRUNING AND LINE CLEARANCE SPECIFICATIONSII. LINE CLEARANCELine clearance distances attained during tree pruning operations shall vary depending on the power linevoltage and the type of trees encountered. Higher voltage power lines require greater clearances. Fastgrowing trees shall be pruned to provide more clearance from electrical facilities than slow growing trees.The tree pruning operation shall provide clearance as appropriate for the line voltage and average growthrate of the affected trees, with the overall objective of achieving a minimum four (4) to five (5) yearpruning cycle.Line clearing shall begin only after careful consideration of the position occupied by the electric facilityrelative to the adjacent trees, and the growth rate of the affected trees.The clearances specified shall be consistently achieved. Special efforts shall be undertaken forreasonable resolution of any property owner objections or disputes.DISTRIBUTION FACILITIESIf the pruning required to obtain adequate clearance from an electric facility (i.e., leaning pole, low poleheight, sagging wire) would significantly affect the shape of the tree, the Vendor shall consult with the AEInspector to determine if the electric facilities can be adjusted to reduce the pruning required.Telephone or TV Cable facilities shall not be considered in determining line clearances.A) Primary conductors 600 volts to 12,500 volts -Minimum clearance shall be 6 to 8 feet, dependingon the tree species.

Where any discrepancy or contradiction existsbetween this contract document and the ANSI standard, the requirements of the contract document shallprevail.The primary goal for the line clearance tree pruning program is to maintain a safe and reliable electricaltransmission and distribution system. These specifications and requirements prescribe arboriculturalstandards to ensure consistent tree pruning practices, and efficient, economical line clearancemaintenance. They shall provide a basis for determining whether tree pruning is necessary orappropriate, and shall dictate the arboricultural methods to be adhered to in the performance of the workactivity described in this document.The AE is obliged and committed to compliance with the terms and conditions of City of Austin GeneralDevelopment Permit No. GP-05-0000.AEU, and any subsequent extension or renewal. The Vendor shallbe familiar with these terms and conditions, and will ensure that no violations occur as a result of theVendor's actions.All tree work shall conform to approved principles and techniques of modern arboriculture. Proper lineclearance tree pruning shall direct tree growth away from electrical conductors and facilities, extendpruning cycles, and reduce the overall amount of future pruning work required. The AE shall determinethe appropriate distances between all plant or tree growth and electrical facilities. Because of thedifficulty in developing line clearance tree pruning policies which would cover all circumstances, the AEreserves the right to assess, on a case-by-case basis, any special situations where the strict applicationof these specifications and requirements might be impractical or inappropriate.I. PRUNING SPECIFICATIONSThe following specifications shall apply to all tree pruning unless otherwise specified herein. For thepurpose of this line clearance tree pruning contract, a tree shall be considered to be a self-supportingwoody perennial plant, having a trunk diameter of no less than two inches (2") at maturity, measured atfour and one-half (4-1/2) feet (Qiameter at Breast Height, or DBH), with one (1) or more branchesdeveloping from the stem or trunk. Plants containing multiple trunks or stems, each of which exceeds twoinches (2") in diameter (DBH), will be considered to be one (1) tree when those stems originate from acommon root crown, or are less than six inches (6") apart.A) The most important technique in pruning a tree is the collar cut. This term refers to the final pruningcut to remove a limb just outside the raised portion (branch collar) of the branch junction with thetrunk or another limb. A proper collar cut will minimize the exposed surface area of the cut surface.All limb or branch removals shall be performed using the collar cut method.B) When removing a lateral branch at its point of origin on the trunk or parent limb, the final cut shall bemade in branch tissue close to the trunk or parent limb, without cutting into the branch bark ridge orcollar, or leaving a stub. (ANSI A300 Standard 5.3.2 and 5.3.3).C) When removing a dead branch, the final cut shall be made just outside the collar of live tissue. If thecollar has grown out along the branch stub, only the dead stub shall be removed. The live collar shallbe left intact and uninjured. (ANSI A300 Standard, 5.3.5).D) No stub and/or flush cuts shall be left on the trunk or supporting branch unless specifically requestedby the property owner and specifically approved by the AE, prior to the removal of branch or limb.11/07/05 1 Specifications and GuidelinesOriginal TreeSpec 97 05 Update.doc AUSTIN ENERGYTREE PRUNING AND LINE CLEARANCE SPECIFICATIONSE) Old stubs from prior stub cuts that have re-sprouted and re-grown into the electrical conductor cleararea shall be removed to the branch collar of the stubbed-off limb, or may be pruned to a lateral limb,behind the stub, large enough to assume the terminal role, consistent with these pruningspecifications and requirements.F) The three-cut method should be used in order to prevent ripping or peeling of the bark on the trunk orparent stem from which the limb is removed.G) When a leader, dominate or co-dominate stem is to be removed, it shall be removed back to a laterallimb or branch no less than one-third (1/3) of the diameter of the portion being removed.H) When removal of an entire lateral limb back to the branch collar on the parent stem would removeexcessive branch tissue and foliage, and is not necessary to obtain the required line clearance, theleader of a lateral limb may be pruned to a lateral limb large enough to assume the terminal role. Inmaking a thinning cut in this instance, the final cut shall be beyond the branch bark ridge of thecrotch.I) All final lateral pruning shall be concluded at a branch collar on the supporting branches or trunksgrowing away from the electrical facility, so that the growth of the tree is directed away from electricalfacilities (directional pruning).J) Directional pruning is used to redirect side growth away from the electrical facilities. Limbs growingtowards the facilities are removed to appropriate limbs or trunk to train the tree away from theelectrical facilities.K) Drop crotch pruning is used to reduce the height of a tree by removing dominant or co-dominantstems in the center of the crown of the tree and direct growth away from the electric lines overhead.This method of line clearance pruning is most often used when the conductors are involved with thecenter of the tree crown. Limbs should be cut at the branch bark ridge, consistent with properarboricultural techniques, as detailed in B) above.L) All tree pruning wounds and other wounds caused by AE operations on oak trees shall be treatedpromptly with a thin but complete covering of an approved non-phytotoxic tree wound dressing.Wounds on oaks shall be treated before moving to another part of the tree, and prior to descendingthe tree. All oak stumps shall be painted with a tree wound dressing, as required on all oak wounds.No other tree species shall be painted unless specifically requested by the property owner, ordirected by the AE. (ANSI A300 Standard, 5.4.1).M) Rips and peels are not acceptable and shall be avoided, but if they occur, tree wound dressing maybe applied, as a cosmetic treatment only. Tree wound dressing may be applied as a cosmetictreatment on large wounds.N) To help prevent the spread of various types of tree diseases, all cutting tools (hand and powered)shall be surface disinfected with a seventy percent (70%) or higher solution of alcohol and water.Other disinfectants, such as Lysol and 50% chlorine bleach (sodium hypochlorite) and water solutionmay be substituted. Disinfectants shall be applied prior to commencing any pruning on the job site,and immediately after pruning oaks suspected to be infected with oak wilt in a designated diseasedarea.11/07/05 2 Specifications and GuidelinesOriginal TreeSpec 97 05 Update.doc AUSTIN ENERGYTREE PRUNING AND LINE CLEARANCE SPECIFICATIONSII. LINE CLEARANCELine clearance distances attained during tree pruning operations shall vary depending on the power linevoltage and the type of trees encountered. Higher voltage power lines require greater clearances. Fastgrowing trees shall be pruned to provide more clearance from electrical facilities than slow growing trees.The tree pruning operation shall provide clearance as appropriate for the line voltage and average growthrate of the affected trees, with the overall objective of achieving a minimum four (4) to five (5) yearpruning cycle.Line clearing shall begin only after careful consideration of the position occupied by the electric facilityrelative to the adjacent trees, and the growth rate of the affected trees.The clearances specified shall be consistently achieved. Special efforts shall be undertaken forreasonable resolution of any property owner objections or disputes.DISTRIBUTION FACILITIESIf the pruning required to obtain adequate clearance from an electric facility (i.e., leaning pole, low poleheight, sagging wire) would significantly affect the shape of the tree, the Vendor shall consult with the AEInspector to determine if the electric facilities can be adjusted to reduce the pruning required.Telephone or TV Cable facilities shall not be considered in determining line clearances.A) Primary conductors 600 volts to 12,500 volts -Minimum clearance shall be 6 to 8 feet, dependingon the tree species.

The objective of Phase Two studies is todetermine the number and type of aquatic organisms which are (a) impinged onthe revolving screens and (b) entrained by the reservoir fill pumps during thefilling of the main cooling reservoir. Phase One studies, conducted in1975-76, resulted in predictions of impingement and entrainment losses andPhase Two is designed to confirm the accuracy of those predictions. Samplingmethods remain the same as in Phase One. Phase One samples were collected atfour locations in the Colorado River, designated as Stations 1,2,3 and 5.Phase Two samples are to be collected only at Station 2, i.e., in the ColoradoRiver adjacent to the Reservoir Makeup Pumping Facility (RMPF) and in theSiltation Basin, the body of water located between the RMPF revolving screenstructure and the pump structure.On 11 July 1983, cooling reservoir filling operations began at the SouthTexas Project in Matagorda County, Texas. This report presents data collectedduring July, August and September 1983. After the third week of September, nofurther reservoir filling occurred in 1983 or through the first six months of1984. The data presented in the following report therefore constitute theinformation collected during the period July, 1983, through June, 1984.1 METHODSSAMPLING SCHEDULE AND STATIONSThe aquatic ecology study is divided into two distinct types of studies,impingement and entrainment, requiring different gear types and methodologies.The impingement study is conducted on the revolving screen structure, whichextends 423.5 ft along the west bank of the Colorado River at River Mile 14.6.The entrainment study is conducted at two locations: 1) in the Colorado Riveradjacent to and slightly downstream of the screen structure, and 2) in thesiltation basin between the pump structure and the submerged weir.FIELD AND LABORATORY PROGRAMSImpingementImpingement samples are collected within one week of the start of eachpumping period and weekly thereafter as long as pumping continues. Each week,three samples are collected over a 24-hr period. Prior to the start of eachrevolving screen sample, 2 of the 24 screens are selected at random and runfor 15 min to clean them of accumulated debris. The two screens are thensampled for a 30-min period by placing a tight-fitting dip net with 1/4-inmesh at the lower end of the screenwash trough and filtering all the organismswashed off the screens. While the sample is being collected, hydrology andwater quality parameters are recorded from the siltation basin behind thescreen structure. Surface and bottom readings of water temperature (°C),conductivity (millimhos/cm) and dissolved oxygen (ppm) and a surface readingof pH are recorded as are the number and size of RMPF pumps operating at the2 time of sample collection. The Colorado River flow (cfs) is also noted on thefield data sheets.After the two screens have been sampled for 30 min, the collecting net ischecked for fish, shrimp and crabs. Those found are placed in a plasticsample jar, preserved with 10% buffered formalin and taken to the laboratoryfor identification and enumeration. In the laboratory, each sample is rinsed,sorted by species and the total weight by species and individual lengths(standard length for fish, total for shrimp) or widths (carapace width forcrabs) are recorded. If over 50 individuals of the same species occur in asample, a subsample of 50 is measured. The remainder are counted and theweight of the total is recorded.EntrainmentEntrainment sampling commences within one week of the start of eachcooling reservoir filling period and is conducted at least every other week aslong as pumping continues. A set of samples is collected every 6 hrs over a24-hr period. During the months of March-May and August-December, sampling isdone weekly when the salinity at the -8.5 ft level in the Colorado Riverexceeds 3 ppt. Salinity probes have been mounted on a piling in the rivernear the RMPF at that depth and are connected to a continuous chart recorderto provide a record of salinity fluctuations. The recorder is checked dailyand, if the 3 ppt level is exceeded, the appropriate personnel are notified toinitiate sampling. During the initial months of pumping in 1983,instrumentation and procedural problems resulted in the total loss of3 continuous salinity data. However, salinity data was collected in conjuctionwith biological sampling and is discussed later in this report.Colorado RiverPrior to the start of collection of each set of biological samples,surface and bottom readings of conductivity (which was later converted tosalinity), water temperature and dissolved oxygen were taken at mid-channel ofthe Colorado River near the northern end of the RMPF screen structure.Additional conductivity readings were made at 5-ft intervals between thesurface and bottom. The primary instrument used to measure these parameterswas a Hydrolab Model 8002 with 8100 series probe assembly. A Yellow SpringsInstrument Co. Model 51A temperature and dissolved oxygen meter and anAmerican Optical Co. hand-held refractometer were used as a backup to theprimary system. Surface pH was measured with a portable Altex Model 531153 pHmeter and water transparency was determined using a 200-mm diameter Secchidisc.A 0.5-m diameter, 3:1 (length:mouth diameter) plankton net with 0.5-mmsquare mesh was used to collect plankton samples at mid-channel of theColorado River. Samples were collected at the surface, mid-depth (10 ft) andnear the bottom. The plankton net was attached to a sled to keep the netabout 4 inches above the bottom during towing for the bottom sample. AGeneral Oceanics Model 2030 digital flowmeter mounted in the center of the netmouth was used to calculate the volume of water filtered during each tow. Theflowmeter reading was recorded prior to and at the conclusion of each plankton4 tow. Each mid-channel sample was collected by lowering the net to theappropriate depth with the boat in a stationary position. All tows were madein the direction of river flow, i.e. north to south. Each tow startedapproximately 50 yds upstream of the RMPF and continued to a pointapproximately 50 yds downstream of the RMPF. Bottom tows were made at aslower forward speed than either the mid-depth or surface tows to insure thatthe net sled remained on the bottom. A wire-angle indicator and graduatedtowline were used to verify the depth from which the mid-depth sample wascollected. This was maintained at about 10 ft as the depth of the channel isapproximately 20 ft. The surface sample was taken by towing the net with theupper edge of the net mouth a few inches below the water's surface. At theend of each tow, the boat was held stationary in the river while the net wasquickly brought to the surface. This was done in an effort to minimizecontamination of the sample due to the net being towed upward through thewater column above the level being sampled. At the end of each tow the netwas rinsed from the outside to wash the sample contents into the cod endbucket. The sample was then placed in a plastic jar, labeled and preservedwith 5% formalin. Rose Bengal was added to each sample several days beforesample workup to facilitate visual separation of the organisms from trash anddetritus.A 0.5-m diameter, 3:1 (length:mouth diameter) plankton net with 0.5-mmsquare mesh equipped with a General Oceanics model 2030 digital flowmeter anda cable depressor was used to collect oblique-tow plankton samples near thewest shoreline of the Colorado River. Before each sample was collected, theflowmeter reading was recorded. After lowering the net to the bottom at the5 north end of the RMPF screen structure, the net was towed downstream while thetowline and attached plankton net was slowly reeled in. When the net reachedthe surface, the boat was stopped, the net raised and the flowmeter readingrecorded. After rinsing the net down from the outside, the sample was placedin a plastic jar, labeled and preserved with 5% buffered formalin. RoseBengal was added to each sample as described above.A 20-ft (headrope length) otter trawl, with 1 1/4-in stretched mesh in theupper end and 3/8-in stretched mesh in the cod end, was towed on the bottomparallel to shore at mid-channel of the Colorado River to determine thespecies composition and abundance of the nekton (fish and macroinvertebrates).Tows were of 5 min duration and were made in the direction of water flow.Each trawl tow began approximately 50 yds upstream of the RMPF. Each samplewas emptied into a large tub and inspected for larger specimens of fish andinvertebrates. These were identitied, weighed, measured and returned to theriver. The remainder of the sample was preserved in 10% formalin and taken tothe laboratory for analysis.Shallow shoreline populations of fish and invertebrates in the vicinity ofthe RMPF were sampled by use of a two-man bag seine. A 20-ft long x 6-ft highx 6-ft deep seine, with 1/2-in stretched mesh in the body and 1/4-in acewebbing in the bag, was pulled for a distance of approximately 75 ft along thewest shore line downstream of the RMPF. The seine collections were made bypulling the seine in the upstream direction (south to north) as the currenthelps in holding the bag of the seine open. Specimens taken by seining werehandled as described above for trawl samples.6 Siltation BasinThe method originally chosen to sample organisms from the siltation basinwas to pump water to the top of the RMPF pump structure deck where it would befiltered through an ichthyoplankton net. During the first two collectingtrips, on 14-15 July and 27-28 July 1983, repeated attempts were made tocollect samples by this method. However, the pump could not overcome the headinvolved. Therefore, no siltation basin samples were collected on thosedates. On the third trip, surface plankton samples were collected byhand-towing a 0.5-m (mouth diameter) ichthyoplankton net, having 0.5-mm squaremesh, parallel to the front wall of the pump structure. Hand-towing the net ata deeper level in the water was not attempted because of the danger of the netbeing pulled into the mouth of one of the operating pumps. Towing the net byboat in the siltation basin was not possible because of the small size of thebasin and the presence of several submerged obstructions.7 RESULTS AND DISCUSSIONHYDROLOGY AND WATER QUALITYWater temperature, pH, turbidity (Secchi disc) and dissolved oxygen at theColorado River station are given in Table 1. Tables 2 & 3 show theconductivity measurements and the derived salinity values. Water temperature,salinity, dissolved oxygen and pH in the RMPF siltation basin are given inTable 4. Water temperature, conductivity, salinity, dissolved oxygen and pHat the RMPF revolving screens are given in Table 5.On 14-15 July a wedge of salt water was present in the Colorado Riverextending up to about 10 to 15 ft below the surface. The wedge was 2.3 to3.0 C warmer than the overlying fresh water and was low in dissolved oxygen(maximum of 0.9 ppm).On 27-28 July no salt wedge was present (0.9 ppt at bottom) and freshoxygenated water extended to the bottom. A salt wedge was re-established on9-10 August and 15-16 September extending up to 10 to 15 ft from the surfaceand even up to 5 ft on 9 August. The bottom oxygen was again very low onthese two days (0.1 to 0.5 ppm).In the RMPF siltation basin the water quality of the surface water wassimilar to that of the surface water in the river on the same dates.At the revolving screens the water quality was similar to that of theriver at comparable depths on the same dates.8 River flow during the sampling periods is shown in Table 6 and the dailyvolume of water pumped into the cooling reservoir during July -September,1983 is shown in Table 7.MACROZOOPLANKTON AND ICHTHYOPLANKTONSamples collected by 0.5-m plankton net in the Colorado River yielded 49taxa of invertebrates and 10 taxa of vertebrates, (Table 8). The dominantinvertebrate forms were cladocerans, or water fleas, which are all freshwaterorganisms; copepods, both freshwater and estuarine-marine in origin; andMalacostraca, consisting of estuarine mysid shrimp, freshwater and estuarineamphipods, estuarine-marine penaeids (commercial shrimp), freshwater andestuarine carideans (grass and river shrimp) and various species of crabs.The fish were represented by as many as 10 taxa, but they were rarely a majorcomponent of any single sample. On some occasions, however, the bay anchovydid occur in large numbers.Tables 9-12 show the temporal and spatial variations in density ofinvertebrates collected from the Colorado River on each of the four samplingtrips. The largest total numbers of organisms were collected in mid-depth,bottom and oblique tows and also innight collections. Higher densitiesappear to be closely related to the presence of a salt wedge at the -10 ftlevel and deeper, as occurred on 9-10 August and 15-16 September (See Table3). A salt wedge also occurred on 14-15 July, but no bottom samples werecollected on that trip because the bottom plankton net was lost during thefirst tow of the day.9 The most ubiquitous species, as well as the most abundant, was the zoealarval stage of the xanthid mud crab, Rhithropanopeus harrisii. The secondmost abundant forms were the zoeal and postlarval stages of the ghost shrimp,Callianassa spp. The postlarval stage of the brown shrimp, Penaeus aztecus,and the'white shrimp, P. setiferus, and the megalops and juvenile stages ofthe blue crab, Callinectes sapidus, were collected only sporadically and neverin very high densities. It is possible that some of the crab megalopsrepresented the non-commercial pygmy blue crab, C. similis, which isimpossible to differentiate from C. sapidus at this stage of development.A list of the common and scientific names of the egg, larval and juvenilestages of the fish taxa collected from both the Colorado River and thesiltation basin is found in Table 13.Tables 14-17 show the changes in abundance which were observed, bothtemporally and spatially, in the Colorado River ichthyoplankton during thestudy period. The most notable trends seen in this limited amount of dataare: (a) the relatively small numbers of ichthyoplankters from the surfaceand oblique tows compared to the large numbers from the mid-depth and bottomtows and (b) the greater numbers of larval and juvenile fish in samples col-lected at night, regardless of depth. The bay anchovy was the most abundantspecies, due primarily to its peak in abundance on 27-28 July. One possibleexplanation for the anchovy's apparent high level of abundance is due to thelow salinity observed from surface to bottom on those dates (see Table 3).The bay anchovy is an estuarine species preferring salinities in excess of 10ppt, and the fact they were caught in such large numbers during a period of10 high freshwater flow and salinities less than 1 ppt indicates they were understress. This made them more susceptible to capture by a plankton net thanthey would be under normal conditions, when they are probably just asabundant, especially in the salt wedge (mid-depth to the bottom). The onlyother taxa collected regularly were two species of gobies and one categorycalled Gobiidae larvae. The darter goby, Gobionellus boleosoma, and the nakedgoby, Gobiosoma bosci, are both estuarine, mid-depth to bottom dwellingspecies which are common over mud substrates in all Texas estuaries. Thelarvae of the two genera are indistinguishable below about 5 mm, thusresulting in the unidentified Gobiidae larvae category.Because ichthyoplankton were taken in such small numbers in the samplescollected in the siltation basin, they are included with the invertebrates onthe tables showing temporal changes in abundance of organisms at this location(Tables 18 and 19). Penaeus setiferus (white shrimp) postlarvae peaked inabundance during the night on both collecting dates, but were otherwise foundonly in low densities. Macrobrachium ohione, one of the river shrimps, andRhithropanopeus harrisii, a xanthid mud crab, were the most abundant speciesin the basin. M. ohione were much more abundant in the basin than they werein the Colorado River on the same dates (see Tables 11 and 12). This iseasily explained by the fact that river shrimp zoeae and juveniles, the lifestages collected in these samples, prefer shoreline areas with protectivevegetation cover to open river channel habitat. The front wall of the RMPFpump structure, along which the plankton net was towed, afforded a semblanceof shoreline habitat by accumulating floating pieces of wood, dead grasses andother types of vegetative material. Further evidence for the shoreline nature11 of the siltation basin sampling location is the occurrence of Gambusiaaffinis, a shallow shoreline species of fish known as the mosquitofish, onboth the 9-10 August and 15-16 September collecting dates. The megalops andjuvenile life stages of the blue crab, Callinectes sapidus, were the onlyother taxa occurring in fairly high densities, and this was only on 9-10August when they also peaked in abundance in river samples. Notable by itsabsence from the siltation basin were Callianassa spp. zoeae, which were veryabundant in the river. They are, however, primarily a mid-depth and bottomdwelling group and the sampling technique used was not adequate for detectingtheir presence.12 MACROINVERTEBRATES AND FISHTrawl and seine samples yielded eight macroinvertebrate species, fiveshrimp, two crabs and a crayfish (Table 20 and Tables 21-28). The grassshrimp, Palaemonetes paludosus, the river shrimp, Macrobrachium ohione, andthe crayfish, Procambarus blandingi acutus, are freshwater animals whereas thethree penaeid shrimp and the two crabs are estuarine and marine. The bluecrab, Callinectes sapidus, however, is tolerant ot fresh water and is known tomigrate far upstream in rivers.The river shrimp was the most common invertebrate (818) closely followedby the white shrimp, Peneaus setiferus (760). The majority of the rivershrimp were caught in trawls on 27-28 July while the majority of the whiteshrimp were caught in seines on 15-16 September.Twenty-nine species of fish were collected in trawl and seine samples. Ofthese, four species are freshwater and 25 are estuarine or marine. Thegreatest number of species of fish (16) as well as the greatest number ofindividuals (3697) were recorded from the trawls taken on 27-28 July.However, because the majority (97.7%) of the fish caught that day were bayanchovies, Anchoa mitchilli, the diversity for that day is low. Except forthe large number of anchovies on this one day, the catches in the trawls andseines were similar in number of species and total number of individualstaken.13 Impingement samples yielded 6 macroinvertebrate taxa, 2 of which werefound only in the impingement samples (Tables 29-33). Palaemonid shrimpdominated the species list (4 of 6 taxa), but the majority of individuals wereblue crabs. With few exceptions the individuals were small, less than 30 mmin length (or width in the case of crabs).Three species of fish were collected in the impingement samples, eachrepresented by one individual. The green sunfish, Lepomis cyanellus, was theonly freshwater fish and the only fish species caught by impingement that wasnot caught by trawl or seine.14 TABLE 1TEMPORAL VARIATIONS IN TEMPERATURE,

The objective of Phase Two studies is todetermine the number and type of aquatic organisms which are (a) impinged onthe revolving screens and (b) entrained by the reservoir fill pumps during thefilling of the main cooling reservoir. Phase One studies, conducted in1975-76, resulted in predictions of impingement and entrainment losses andPhase Two is designed to confirm the accuracy of those predictions. Samplingmethods remain the same as in Phase One. Phase One samples were collected atfour locations in the Colorado River, designated as Stations 1,2,3 and 5.Phase Two samples are to be collected only at Station 2, i.e., in the ColoradoRiver adjacent to the Reservoir Makeup Pumping Facility (RMPF) and in theSiltation Basin, the body of water located between the RMPF revolving screenstructure and the pump structure.On 11 July 1983, cooling reservoir filling operations began at the SouthTexas Project in Matagorda County, Texas. This report presents data collectedduring July, August and September 1983. After the third week of September, nofurther reservoir filling occurred in 1983 or through the first six months of1984. The data presented in the following report therefore constitute theinformation collected during the period July, 1983, through June, 1984.1 METHODSSAMPLING SCHEDULE AND STATIONSThe aquatic ecology study is divided into two distinct types of studies,impingement and entrainment, requiring different gear types and methodologies.The impingement study is conducted on the revolving screen structure, whichextends 423.5 ft along the west bank of the Colorado River at River Mile 14.6.The entrainment study is conducted at two locations: 1) in the Colorado Riveradjacent to and slightly downstream of the screen structure, and 2) in thesiltation basin between the pump structure and the submerged weir.FIELD AND LABORATORY PROGRAMSImpingementImpingement samples are collected within one week of the start of eachpumping period and weekly thereafter as long as pumping continues. Each week,three samples are collected over a 24-hr period. Prior to the start of eachrevolving screen sample, 2 of the 24 screens are selected at random and runfor 15 min to clean them of accumulated debris. The two screens are thensampled for a 30-min period by placing a tight-fitting dip net with 1/4-inmesh at the lower end of the screenwash trough and filtering all the organismswashed off the screens. While the sample is being collected, hydrology andwater quality parameters are recorded from the siltation basin behind thescreen structure. Surface and bottom readings of water temperature (°C),conductivity (millimhos/cm) and dissolved oxygen (ppm) and a surface readingof pH are recorded as are the number and size of RMPF pumps operating at the2 time of sample collection. The Colorado River flow (cfs) is also noted on thefield data sheets.After the two screens have been sampled for 30 min, the collecting net ischecked for fish, shrimp and crabs. Those found are placed in a plasticsample jar, preserved with 10% buffered formalin and taken to the laboratoryfor identification and enumeration. In the laboratory, each sample is rinsed,sorted by species and the total weight by species and individual lengths(standard length for fish, total for shrimp) or widths (carapace width forcrabs) are recorded. If over 50 individuals of the same species occur in asample, a subsample of 50 is measured. The remainder are counted and theweight of the total is recorded.EntrainmentEntrainment sampling commences within one week of the start of eachcooling reservoir filling period and is conducted at least every other week aslong as pumping continues. A set of samples is collected every 6 hrs over a24-hr period. During the months of March-May and August-December, sampling isdone weekly when the salinity at the -8.5 ft level in the Colorado Riverexceeds 3 ppt. Salinity probes have been mounted on a piling in the rivernear the RMPF at that depth and are connected to a continuous chart recorderto provide a record of salinity fluctuations. The recorder is checked dailyand, if the 3 ppt level is exceeded, the appropriate personnel are notified toinitiate sampling. During the initial months of pumping in 1983,instrumentation and procedural problems resulted in the total loss of3 continuous salinity data. However, salinity data was collected in conjuctionwith biological sampling and is discussed later in this report.Colorado RiverPrior to the start of collection of each set of biological samples,surface and bottom readings of conductivity (which was later converted tosalinity), water temperature and dissolved oxygen were taken at mid-channel ofthe Colorado River near the northern end of the RMPF screen structure.Additional conductivity readings were made at 5-ft intervals between thesurface and bottom. The primary instrument used to measure these parameterswas a Hydrolab Model 8002 with 8100 series probe assembly. A Yellow SpringsInstrument Co. Model 51A temperature and dissolved oxygen meter and anAmerican Optical Co. hand-held refractometer were used as a backup to theprimary system. Surface pH was measured with a portable Altex Model 531153 pHmeter and water transparency was determined using a 200-mm diameter Secchidisc.A 0.5-m diameter, 3:1 (length:mouth diameter) plankton net with 0.5-mmsquare mesh was used to collect plankton samples at mid-channel of theColorado River. Samples were collected at the surface, mid-depth (10 ft) andnear the bottom. The plankton net was attached to a sled to keep the netabout 4 inches above the bottom during towing for the bottom sample. AGeneral Oceanics Model 2030 digital flowmeter mounted in the center of the netmouth was used to calculate the volume of water filtered during each tow. Theflowmeter reading was recorded prior to and at the conclusion of each plankton4 tow. Each mid-channel sample was collected by lowering the net to theappropriate depth with the boat in a stationary position. All tows were madein the direction of river flow, i.e. north to south. Each tow startedapproximately 50 yds upstream of the RMPF and continued to a pointapproximately 50 yds downstream of the RMPF. Bottom tows were made at aslower forward speed than either the mid-depth or surface tows to insure thatthe net sled remained on the bottom. A wire-angle indicator and graduatedtowline were used to verify the depth from which the mid-depth sample wascollected. This was maintained at about 10 ft as the depth of the channel isapproximately 20 ft. The surface sample was taken by towing the net with theupper edge of the net mouth a few inches below the water's surface. At theend of each tow, the boat was held stationary in the river while the net wasquickly brought to the surface. This was done in an effort to minimizecontamination of the sample due to the net being towed upward through thewater column above the level being sampled. At the end of each tow the netwas rinsed from the outside to wash the sample contents into the cod endbucket. The sample was then placed in a plastic jar, labeled and preservedwith 5% formalin. Rose Bengal was added to each sample several days beforesample workup to facilitate visual separation of the organisms from trash anddetritus.A 0.5-m diameter, 3:1 (length:mouth diameter) plankton net with 0.5-mmsquare mesh equipped with a General Oceanics model 2030 digital flowmeter anda cable depressor was used to collect oblique-tow plankton samples near thewest shoreline of the Colorado River. Before each sample was collected, theflowmeter reading was recorded. After lowering the net to the bottom at the5 north end of the RMPF screen structure, the net was towed downstream while thetowline and attached plankton net was slowly reeled in. When the net reachedthe surface, the boat was stopped, the net raised and the flowmeter readingrecorded. After rinsing the net down from the outside, the sample was placedin a plastic jar, labeled and preserved with 5% buffered formalin. RoseBengal was added to each sample as described above.A 20-ft (headrope length) otter trawl, with 1 1/4-in stretched mesh in theupper end and 3/8-in stretched mesh in the cod end, was towed on the bottomparallel to shore at mid-channel of the Colorado River to determine thespecies composition and abundance of the nekton (fish and macroinvertebrates).Tows were of 5 min duration and were made in the direction of water flow.Each trawl tow began approximately 50 yds upstream of the RMPF. Each samplewas emptied into a large tub and inspected for larger specimens of fish andinvertebrates. These were identitied, weighed, measured and returned to theriver. The remainder of the sample was preserved in 10% formalin and taken tothe laboratory for analysis.Shallow shoreline populations of fish and invertebrates in the vicinity ofthe RMPF were sampled by use of a two-man bag seine. A 20-ft long x 6-ft highx 6-ft deep seine, with 1/2-in stretched mesh in the body and 1/4-in acewebbing in the bag, was pulled for a distance of approximately 75 ft along thewest shore line downstream of the RMPF. The seine collections were made bypulling the seine in the upstream direction (south to north) as the currenthelps in holding the bag of the seine open. Specimens taken by seining werehandled as described above for trawl samples.6 Siltation BasinThe method originally chosen to sample organisms from the siltation basinwas to pump water to the top of the RMPF pump structure deck where it would befiltered through an ichthyoplankton net. During the first two collectingtrips, on 14-15 July and 27-28 July 1983, repeated attempts were made tocollect samples by this method. However, the pump could not overcome the headinvolved. Therefore, no siltation basin samples were collected on thosedates. On the third trip, surface plankton samples were collected byhand-towing a 0.5-m (mouth diameter) ichthyoplankton net, having 0.5-mm squaremesh, parallel to the front wall of the pump structure. Hand-towing the net ata deeper level in the water was not attempted because of the danger of the netbeing pulled into the mouth of one of the operating pumps. Towing the net byboat in the siltation basin was not possible because of the small size of thebasin and the presence of several submerged obstructions.7 RESULTS AND DISCUSSIONHYDROLOGY AND WATER QUALITYWater temperature, pH, turbidity (Secchi disc) and dissolved oxygen at theColorado River station are given in Table 1. Tables 2 & 3 show theconductivity measurements and the derived salinity values. Water temperature,salinity, dissolved oxygen and pH in the RMPF siltation basin are given inTable 4. Water temperature, conductivity, salinity, dissolved oxygen and pHat the RMPF revolving screens are given in Table 5.On 14-15 July a wedge of salt water was present in the Colorado Riverextending up to about 10 to 15 ft below the surface. The wedge was 2.3 to3.0 C warmer than the overlying fresh water and was low in dissolved oxygen(maximum of 0.9 ppm).On 27-28 July no salt wedge was present (0.9 ppt at bottom) and freshoxygenated water extended to the bottom. A salt wedge was re-established on9-10 August and 15-16 September extending up to 10 to 15 ft from the surfaceand even up to 5 ft on 9 August. The bottom oxygen was again very low onthese two days (0.1 to 0.5 ppm).In the RMPF siltation basin the water quality of the surface water wassimilar to that of the surface water in the river on the same dates.At the revolving screens the water quality was similar to that of theriver at comparable depths on the same dates.8 River flow during the sampling periods is shown in Table 6 and the dailyvolume of water pumped into the cooling reservoir during July -September,1983 is shown in Table 7.MACROZOOPLANKTON AND ICHTHYOPLANKTONSamples collected by 0.5-m plankton net in the Colorado River yielded 49taxa of invertebrates and 10 taxa of vertebrates, (Table 8). The dominantinvertebrate forms were cladocerans, or water fleas, which are all freshwaterorganisms; copepods, both freshwater and estuarine-marine in origin; andMalacostraca, consisting of estuarine mysid shrimp, freshwater and estuarineamphipods, estuarine-marine penaeids (commercial shrimp), freshwater andestuarine carideans (grass and river shrimp) and various species of crabs.The fish were represented by as many as 10 taxa, but they were rarely a majorcomponent of any single sample. On some occasions, however, the bay anchovydid occur in large numbers.Tables 9-12 show the temporal and spatial variations in density ofinvertebrates collected from the Colorado River on each of the four samplingtrips. The largest total numbers of organisms were collected in mid-depth,bottom and oblique tows and also innight collections. Higher densitiesappear to be closely related to the presence of a salt wedge at the -10 ftlevel and deeper, as occurred on 9-10 August and 15-16 September (See Table3). A salt wedge also occurred on 14-15 July, but no bottom samples werecollected on that trip because the bottom plankton net was lost during thefirst tow of the day.9 The most ubiquitous species, as well as the most abundant, was the zoealarval stage of the xanthid mud crab, Rhithropanopeus harrisii. The secondmost abundant forms were the zoeal and postlarval stages of the ghost shrimp,Callianassa spp. The postlarval stage of the brown shrimp, Penaeus aztecus,and the'white shrimp, P. setiferus, and the megalops and juvenile stages ofthe blue crab, Callinectes sapidus, were collected only sporadically and neverin very high densities. It is possible that some of the crab megalopsrepresented the non-commercial pygmy blue crab, C. similis, which isimpossible to differentiate from C. sapidus at this stage of development.A list of the common and scientific names of the egg, larval and juvenilestages of the fish taxa collected from both the Colorado River and thesiltation basin is found in Table 13.Tables 14-17 show the changes in abundance which were observed, bothtemporally and spatially, in the Colorado River ichthyoplankton during thestudy period. The most notable trends seen in this limited amount of dataare: (a) the relatively small numbers of ichthyoplankters from the surfaceand oblique tows compared to the large numbers from the mid-depth and bottomtows and (b) the greater numbers of larval and juvenile fish in samples col-lected at night, regardless of depth. The bay anchovy was the most abundantspecies, due primarily to its peak in abundance on 27-28 July. One possibleexplanation for the anchovy's apparent high level of abundance is due to thelow salinity observed from surface to bottom on those dates (see Table 3).The bay anchovy is an estuarine species preferring salinities in excess of 10ppt, and the fact they were caught in such large numbers during a period of10 high freshwater flow and salinities less than 1 ppt indicates they were understress. This made them more susceptible to capture by a plankton net thanthey would be under normal conditions, when they are probably just asabundant, especially in the salt wedge (mid-depth to the bottom). The onlyother taxa collected regularly were two species of gobies and one categorycalled Gobiidae larvae. The darter goby, Gobionellus boleosoma, and the nakedgoby, Gobiosoma bosci, are both estuarine, mid-depth to bottom dwellingspecies which are common over mud substrates in all Texas estuaries. Thelarvae of the two genera are indistinguishable below about 5 mm, thusresulting in the unidentified Gobiidae larvae category.Because ichthyoplankton were taken in such small numbers in the samplescollected in the siltation basin, they are included with the invertebrates onthe tables showing temporal changes in abundance of organisms at this location(Tables 18 and 19). Penaeus setiferus (white shrimp) postlarvae peaked inabundance during the night on both collecting dates, but were otherwise foundonly in low densities. Macrobrachium ohione, one of the river shrimps, andRhithropanopeus harrisii, a xanthid mud crab, were the most abundant speciesin the basin. M. ohione were much more abundant in the basin than they werein the Colorado River on the same dates (see Tables 11 and 12). This iseasily explained by the fact that river shrimp zoeae and juveniles, the lifestages collected in these samples, prefer shoreline areas with protectivevegetation cover to open river channel habitat. The front wall of the RMPFpump structure, along which the plankton net was towed, afforded a semblanceof shoreline habitat by accumulating floating pieces of wood, dead grasses andother types of vegetative material. Further evidence for the shoreline nature11 of the siltation basin sampling location is the occurrence of Gambusiaaffinis, a shallow shoreline species of fish known as the mosquitofish, onboth the 9-10 August and 15-16 September collecting dates. The megalops andjuvenile life stages of the blue crab, Callinectes sapidus, were the onlyother taxa occurring in fairly high densities, and this was only on 9-10August when they also peaked in abundance in river samples. Notable by itsabsence from the siltation basin were Callianassa spp. zoeae, which were veryabundant in the river. They are, however, primarily a mid-depth and bottomdwelling group and the sampling technique used was not adequate for detectingtheir presence.12 MACROINVERTEBRATES AND FISHTrawl and seine samples yielded eight macroinvertebrate species, fiveshrimp, two crabs and a crayfish (Table 20 and Tables 21-28). The grassshrimp, Palaemonetes paludosus, the river shrimp, Macrobrachium ohione, andthe crayfish, Procambarus blandingi acutus, are freshwater animals whereas thethree penaeid shrimp and the two crabs are estuarine and marine. The bluecrab, Callinectes sapidus, however, is tolerant ot fresh water and is known tomigrate far upstream in rivers.The river shrimp was the most common invertebrate (818) closely followedby the white shrimp, Peneaus setiferus (760). The majority of the rivershrimp were caught in trawls on 27-28 July while the majority of the whiteshrimp were caught in seines on 15-16 September.Twenty-nine species of fish were collected in trawl and seine samples. Ofthese, four species are freshwater and 25 are estuarine or marine. Thegreatest number of species of fish (16) as well as the greatest number ofindividuals (3697) were recorded from the trawls taken on 27-28 July.However, because the majority (97.7%) of the fish caught that day were bayanchovies, Anchoa mitchilli, the diversity for that day is low. Except forthe large number of anchovies on this one day, the catches in the trawls andseines were similar in number of species and total number of individualstaken.13 Impingement samples yielded 6 macroinvertebrate taxa, 2 of which werefound only in the impingement samples (Tables 29-33). Palaemonid shrimpdominated the species list (4 of 6 taxa), but the majority of individuals wereblue crabs. With few exceptions the individuals were small, less than 30 mmin length (or width in the case of crabs).Three species of fish were collected in the impingement samples, eachrepresented by one individual. The green sunfish, Lepomis cyanellus, was theonly freshwater fish and the only fish species caught by impingement that wasnot caught by trawl or seine.14 TABLE 1TEMPORAL VARIATIONS IN TEMPERATURE,

First cut at manpower loading for PIP # 081270- Spent Fuel management ProjectLast Thursday (Aug 11) there was a Pre-PRT review of the DRAFT for PIP #081270. The PIP waspresented to PRT on Wednesday (Aug 17).At the Pre-PRT meeting we recognized some changes to the first DRAFT manpower loadings. Some butnot all of these were incorporated into the PIP that was presented to PRT.Today I met with Joe Nagle and further changes were identified. Two changes were to re-assign "FuelMovers- Craft labor" and "Vendor Install the SFP Racks" from cost center 932 to the Refueling Team costcenter.With these changes, the following NFAD activities are identified in the latest working version of PIP #081270:* NFAD and DED are jointly identified for Design work support (to the vendor) for Installing the SFPRack Modules 12 and 16. This activity is assigned 556 hours for Ul in 2012 and 444 hour for U2 in2012." NFAD is the responsible group for the Criticality Analysis work to be done by a vendor to beselected. The funding is $100,000 in 2012 and $25,000 in 2013; this should be corrected to$250,000 in 2013." NFAD is the responsible group for the NRC's review of the Criticality Analysis. The funding is$200,000 in 2014 and $200,000 in 2015.* NFAD is the responsible group for the Poison Insert design work to be done by a vendor to beselected. The funding is $1,000,000 in 2015 which is identified as "Contingency"; and $1,000,000in 2016.These PIP funding amounts are consistent with NFAD's inputs to date.NFAD needs to consider additional NFAD manpower support that will be required for the on-going spentfuel management work, and which budgets (PIP, baseline, or other) will be used.8/18/2011 AQ-2.

The initial report (McAden et al. 1984)covered the period July 1983 -June 1984. This report presents data from thesampling period July -December 1984. Due to limited pumping during thisperiod, only one set of samples was collected.METHODSAll stations, schedules and methods employed were the same as thosedescribed in the initial report (McAden et al. 1984). A malfunction of the pHmeter precluded pH measurements during sampling.RESULTS AND DISCUSSIONHYDROLOGY AND WATER QUALITYWater temperature, turbidity and dissolved oxygen data from the ColoradoRiver station are shown in Table 1. Conductivity values are given in Table 2,and salinity values are given in Table 3. Water temperature, salinity anddissolved oxygen data from the Reservoir Makeup Pumping Facility (RMPF)siltation basin are given in Table 4. Water temperature, salinity anddissolved oxygen data from the RMPF revolving screens are given in Table 5.1 On 5-6 September a salt wedge was present in the Colorado River, extendingto within 5-10 ft of the surface. The wedge was up to 3.0 C warmer than thelow salinity surface water and contained low dissolved oxygen levels (maximum0.8 ppm at the bottom).Surface water quality in the RMPF siltation basin was similar to that ofthe surface water in the river. Bottom water quality measurements were notmade in the siltation basin.Surface water quality at the revolving screens was similar to the surfacewater quality in the river. However, bottom salinity at the screens was lower(as much as 6.3 ppt) than salinities at comparable river depths.River flow during the sampling period is shown in Table 6 and the dailyvolume of water pumped into the reservoir during July-December 1984 is shownin Table 7.MACROZOOPLANKTON AND ICHTHYOPLANKTONSamples collected by 0.5-m plankton net yielded 29 taxa of invertebratesand 7 taxa of vertebrates (Table 8). The most abundant invertebrates werejellyfish (medusae), copepods (especially Acartia tonsa and Oithona spp.),barnacle nauplii, the zoeae of the brackish water shrimps Palaemonetes spp.and Callianassa spp. and the zoeae of the brackish water crab Rhithropanopeusharrisii. All of the vertebrate taxa consisted of larval and juvenile stagesof both freshwater and estuarine fishes. A single sunfish larva (FamilyCentrarchidae) constituted the freshwater component of the ichthyoplanktonsamples, whereas the bay anchovy and at least two species of gobies dominatedthe estuarine taxa.2 Table 9 shows the variations in macrozooplankton abundance over the 24-hrsample period on 5-6 September 1984 in the Colorado River. The largest totalnumbers of organisms were taken in samples collected at mid-depth and in theoblique tows. Considerably smaller numbers of taxa, as well as numbers withintaxa, were collected at the surface and near the bottom. The reasons forthese spatial differences in abundance can be seen in the hydrological andwater quality measurements made at the times of sample collection(Tables 1-3). There was a layer of very low salinity water at the surface,which contained a paucity of both taxa and numbers of individuals within taxa.The reason for the relative scarcity of zooplankton near the bottom of theriver is the critically low dissolved oxygen levels near the river bottom(Table 1).By far the most commonly found and most abundant of the river zooplanktontaxa was the xanthid mud crab, Rhithropanopeus harrisii. Other abundant formswere jellyfish medusae and the zoeal stages of the ghost shrimp, Callianassaspp. Relatively low numbers of the commercial white shrimp, Penaeussetiferus, and the megalops stage of the blue crab, Callinectes spp., weretaken, although Callinectes spp. megalops did occur at a high density in the0300-hr oblique sample. It is possible that this taxon consisted of both thecommercial blue crab, C. sapidus, and the noncommercial pygmy blue crab, C.similis.A list of the common and scientific names of the larval and juvenilestages of fish taxa collected from both the Colorado River and the siltationbasin is found in Table 10.3 Table 11 shows the temporal and spatial variations in ichthyoplanktonabundance in the Colorado River. The data are too limited to draw anymeaningful conclusions, except to note the total absence of ichthyoplanktonnear the bottom. This is understandable given the low dissolved oxygen levelsnoted in the earlier discussion of macrozooplankton abundance.Table 12 depicts the changes in abundance of macrozooplankton andichthyoplankton over the sampling period. As in the river samples, the zoealstage of the xanthid mud crab, Rhithropanopeus harrisii, was the most abundanttaxon, but unlike the river samples, highest densities occurred during thehours of daylight. The reasons for this are unclear, because siltation basinsamples were collected at the surface and zooplankton abundance in surfacesamples is typically lowest in the daytime. Another commonly occurring,albeit in low densities, taxon was the parasitic fish louse, Argulus spp. 'Nopenaeid shrimp or blue crab larvae were taken from the siltation basin, andonly one ichthyoplankter, an unidentified yolksac larva.MACROINVERTEBRATES AND FISHRepresentatives of 27 species were captured in seine and revolving screensamples during the study (Table 13), but no organisms were captured in thetrawl samples. Critically low dissolved oxygen levels at the bottom of theriver (Table 1) appear to be the limiting factor.4 Six (6) species of macroinvertebrates, including 5 species of shrimp and 1crab, were taken in seine samples (Table 14). Macrobrachium ohione, a smallriver shrimp, was the only freshwater representative, while the estuarine/marine white shrimp, Penaeus setiferus, was the most abundant invertebrate(643 caught).Twenty species of vertebrates, all of which were fish, were caught in theseine samples (Table 14). Of these, only the spotted gar, Lepisosteusocculatus, is freshwater, with the remainder being estuarine and marine. Thefish most commonly caught was the bay anchovy, Anchoa mitchilli (170).Impingement samples (Table 15) yielded 4 macroinvertebrate species, one ofwhich was the pink shrimp, Penaeus duorarum, found only in the impingementsamples. The total catch was 15 individuals. In general, the animals weresmall, 5-64 mm in length.5 | TABLE OF CONTENTSPAGELIST OF TABLES ................... ......................... iINTRODUCTION .................... .......................... 1METHODS ..................... ............................1RESULTS AND DISCUSSION .......... ..... ..................... 1HYDROLOGY AND WATER QUALITY ............. ................ 1MACROZOOPLANKTON AND ICHTHYOPLANKTON ........ ............ 2MACROINVERTEBRATES AND FISH ......................... 4REFERENCES CITED .......... ....... ...................... 6 LIST OF TABLESTABLE PAGE1 TEMPORAL VARIATIONS IN TEMPERATURE, TURBIDITY AND DISSOLVEDOXYGEN AT MID-CHANNEL OF THE COLORADO RIVER, SEPTEMBER 1984 .... ...... 72 TEMPORAL AND SPATIAL VARIATIONS IN CONDUCTIVITY (MILLIMHOS/CM)AT MID-CHANNEL OF THE COLORADO RIVER, SEPTEMBER 1984 ..... ......... 83 TEMPORAL AND SPATIAL VARIATIONS IN SALINITY (PPT) AT MID-CHANNELOF THE COLORADO RIVER, SEPTEMBER 1984 .......... ................. 94 TEMPORAL VARIATIONS IN SURFACE WATER QUALITY PARAMETERS IN THERMPF SILTATION BASIN, SEPTEMBER 1984 ....... ................. ..105 TEMPORAL VARIATIONS IN TEMPERATURE, CONDUCTIVITY, SALINITY ANDDISSOLVED OXYGEN AT THE STP REVOLVING SCREENS, SEPTEMBER 1984 ..... 116 AVERAGE COLORADO RIVER FLOW (CFS) ON DATES OF SAMPLE COLLECTION,SEPTEMBER 1984 ................. ........................... ..127 RESERVOIR MAKEUP PUMPING FACILITY (RMPF) DAILY PUMPAGE (M3),JULY-DECEMBER 1984 .............. .................... ...... ..138 MACROZOOPLANKTON AND FISH TAXA COLLECTED IN THE COLORADO RIVERBY O.5-M PLANKTONINET, SEPTEMBER 1984 ...... ................. ..159 NUMBER (PER 100 M3) OF MACROZOOPLANKTON COLLECTED IN THECOLORADO RIVER BY O.5-M PLANKTON NET ON 5-6 SEPTEMBER 1984 .... ...... 1710 LIST OF FISH TAXA COLLECTED IN O.5-M PLANKTON'.NET SAMPLES FROMTHE COLORADO RIVER (C.R.)

== | ==Dear Mr. Gangluff:== | ||
I received your letter dated May 24, 2007, requesting that the Main Cooling Reservoir (MCR) bedesignated as a closed-cycle recirculating system and as not water in the state.The Texas Commission on Environmental Quality (TCEQ) does not have an official method of"designating" a facility's operation as a closed-cycle recirculating system. However, we have reviewedthe information you submitted and based on our best professional judgement, we consider your facility tobe a closed-cycle recirculating system. As mentioned in your letter, the federal rule governing the 316(b)Phase II cooling water intakes is currently in the process of being suspended. For the time being,implementation of the 316(b) requirements will be based on best professional judgement (BPJ) andsubject to EPA Region VI review.We also concur that the Main Cooling Reservoir (MCR) at your facility does not meet the definition ofwater in the state.If you have any questions, please contact me at (512) 239-2369.Sincerely,Kelly Holligan, LeaderIndustrial TeamWater Quality DivisionKH/jpP.O.

==Dear Mr. Holligan:== | |||
Thank you for meeting with my staff on May 15, 2007 to discuss the South Texas ProjectElectric Generating Station (STPEGS) cooling reservoir and other wastewater discharge pennitissues. Based on our discussion, STP Nuclear Operating Company (STPNOC) is submitting thefollowing information regarding the Main Cooling Reservoir (MCR) and the applicability of theregulations for cooling water intake structures. We are confident that the South Texas ProjectStation (STP) complies with the regulation by employing a closed-cycle recirculating coolingsystem as defined in 40 CFR §125.93. Pursuant to 40 CFR §125.94(a)(1)(i), cooling water flowfor this facility is commensurate with a closed-cycle recirculating cooling system, asdemonstrated below. Additional technical information is included in letters dated March 7, 2005and August 18, 2005 previously submitted to the Texas Commission on Environmental Quality(TCEQ).STP is located on 12,220-acres in Matagorda County, approximately 15 miles southwest of BayCity along the west bank of the Colorado River. The facility consists of two electric-generatingunits, which share a closed-cycle recirculating cooling reservoir. Water from the MCR is passedthrough the cooling loops of both units then returned to the MCR for heat dissipation beforecycling back through the cooling systems.The MCR is a perched, off-channel, on-site industrial cooling impoundment of approximately7,000 acres, impounding over 202,600 acre-feet of cooling water at its maximum operating level.Dikes are installed in the MCR that channel the water flow to maximize circulation time for heatdissipation before the water is recirculated back to the generating units. Blowdown from theMCR to the Colorado River has not occurred since March 1997. Should blowdown be requiredit would occur through an underground pipe that discharges back into the Colorado River. Thispoint is designated as Outfall 001 in the TPDES Permit No. 01908. The MCR is also equippedwith a gated spillway for emergency use. The MCR is not a "water of the U.S." as defined at 40CFR § 122.2. The MCR is not considered a "water of the State" based on internal and externaloutfall designations in the permit. The MCR is on private property and exists solely for Mr. Kelly HolliganMay 24, 2007Page 2industrial cooling. It is not a publicly managed water body and has no recreational uses. Thegeneral public has never had access to the MCR nor is any planned in the foreseeable future.The only sources of new water to the MCR are direct rainfall and make-up water divertedperiodically from the Colorado River, primarily at high river flows. Water from tile ColoradoRiver is pumped approximately I mile via a 108 inch pipe to the MCR. To protect inflows duringlow river flow conditions, the water right for STP includes a special provision to limit diversionfrom the Colorado River to 55% of the flow over 300 cubic feet per second, to protect inflowsduring low river flow conditions. Currently, the intake consists of trash racks, rotating screenswith 3/8 inch mesh and 4 pumps. In addition, the reservoir makeup pumping facility has thefollowing design:" The traveling water screens are flush with the river shoreline;" The maximum approach velocity to the traveling water screens is 0.5 feet per second;" Fish passageways were constructed in the wing walls between the traveling screens tofacilitate fish migration parallel to the screen surfaces; and" A sluice and discharge line was installed for the purpose of returning all impingedorganisms directly to the river, downstream of the intake structure, immediately afterbeing backwashed from the screens.The pumps are operated intermittently based on reservoir level, river flow, and the operability ofthe makeup pumping facility. A cooling reservoir evaporates less water per unit of heatdissipated than a cooling tower, thus dissolved solids build up more slowly over time. This iscomplemented by the designed seepage from the MCR, which maintains the structural integrityof the reservoir embankment. Rainfall further dilutes the dissolved solids in the MCR. Thesefactors minimize the blowdown and make-up required to maintain MCR water quality. As aresult, intake water flow for cooling purposes at STP reflects best technology available (closed-cycle recirculating systems) for minimizing adverse environmental impact.As was discussed in the May 15, 2007 meeting, several provisions of the Phase II rule are in theprocess of being suspended by the U.S. Environmental Protection Agency and the RegionalAdministrators have been authorized to review the applicability of the rule on a case by casebasis using Best Professional Judgment. Based on that authorization and the informritionprovided, STPNOC is requesting that TCEQ designate the MCR as a closed-cycle recirculatingsystem. We are also requesting concurrence that the MCR does not meet the definition of a"water of the State". If you have any questions or require additional information, please contactMs. S. L. Dannbardt at (361) 972-8328.Sincerely,R. A.

Of thethree gear types used to sample the ECP, only the trawl was productive in catching fish. A total of5,589 fish representing two species, sheepshead minnow (Cyprinodon variegatus) and sailfinmolly (Poecilia latipinna), were caught during the study. Sheepshead minnows and sailfin molliesare both common species in Texas and are indigenous to coastal streams, rivers, and estuaries.Mean sizes for both species ranged from 27 to 62 mm total length (TL) (1 inch to 2.5 inches)and were evenly distributed across all sample sections. Sheepshead minnows were mostabundant in quadrant Q2A and sailfin mollies were more abundant in Q4A near the intakestructure. Relative abundance for both species was evenly distributed across quadrants Q2 and03. The total number of fish caught in quadrant Q1, near the discharge, was significantly lowerthan the total number of fish caught in quadrants Q2, Q3, and Q4. Total abundance estimatesderived from the total number of fish caught, total amount of trawling effort and total area covered,indicate that a population of 535,000 fish comprised of both species exists in the ECP. Thisestimate is an extrapolation from the data collected and is based on assumptions about theexisting populations and the sample gear used. Therefore, interpretation of such data may resultin an over estimate of total abundance. It is, however, our belief that fish populations in the ECPare not overabundant.Fish congregating at or near the intake structures may be attributed to the availability of food,structure or cover, and protection from environmental stresses. Under normal operating andenvironment conditions, both species would be expected to avoid the higher water velocitiesfound immediately adjacent to the intake structure. Excessive impingement and entrainment oforganisms is a factor more of how the pumps are operated rather than the total number of fishpresent in the ECP. Prevention of fish congregating in the intake structures may be achieved bymaintaining a constant flow rate at the intake screens and in the pump wells and/or by changingthe chemical composition of the water in the pump wells. If pumps must be shut down, adding05727-800/STPEGS/Fish Population Study May, 2002iv EM~.chemicals such as rotenone, chlorine or other chemicals in the pump wells may create waterconditions unsuitable for fish and prevent them from congregating in the area.Based on the data we collected during this study and discussion with site personnel whoobserved the size/species distribution associated with the Essential Cooling Water Pump 1Cstrainer clogging, the existing population in the ECP is not expected to cause a recurrence of thiscondition as long as precautionary measures are taken to preclude fish from utilizing thescreen/pump well areas during pump shut down and start up. Management recommendations formonitoring and control of the existing population are discussed in the body of the report.05727-800/STPEGS/Fish Population StudyMay, 2002V | ,qQ-4EK1RLSouth Texas ProjectElectric Generating StationWadsworth, TexasEssential Cooling PondFish Population StudyPrepared For:STP Nuclear Operating CompanyP.O.

Sheepshead minnows and sailfin molliesare both common species in Texas and are indigenous to coastal streams, rivers, and estuaries.Mean sizes for both species ranged from 27 to 62 mm total length (TL) (1 inch to 2.5 inches)and were evenly distributed across all sample sections. Sheepshead minnows were mostabundant in quadrant Q2A and sailfin mollies were more abundant in Q4A near the intakestructure. Relative abundance for both species was evenly distributed across quadrants Q2 and03. The total number of fish caught in quadrant Q1, near the discharge, was significantly lowerthan the total number of fish caught in quadrants Q2, Q3, and Q4. Total abundance estimatesderived from the total number of fish caught, total amount of trawling effort and total area covered,indicate that a population of 535,000 fish comprised of both species exists in the ECP. Thisestimate is an extrapolation from the data collected and is based on assumptions about theexisting populations and the sample gear used. Therefore, interpretation of such data may resultin an over estimate of total abundance. It is, however, our belief that fish populations in the ECPare not overabundant.Fish congregating at or near the intake structures may be attributed to the availability of food,structure or cover, and protection from environmental stresses. Under normal operating andenvironment conditions, both species would be expected to avoid the higher water velocitiesfound immediately adjacent to the intake structure. Excessive impingement and entrainment oforganisms is a factor more of how the pumps are operated rather than the total number of fishpresent in the ECP. Prevention of fish congregating in the intake structures may be achieved bymaintaining a constant flow rate at the intake screens and in the pump wells and/or by changingthe chemical composition of the water in the pump wells. If pumps must be shut down, adding05727-800/STPEGS/Fish Population Study May, 2002iv EM~.chemicals such as rotenone, chlorine or other chemicals in the pump wells may create waterconditions unsuitable for fish and prevent them from congregating in the area.Based on the data we collected during this study and discussion with site personnel whoobserved the size/species distribution associated with the Essential Cooling Water Pump 1Cstrainer clogging, the existing population in the ECP is not expected to cause a recurrence of thiscondition as long as precautionary measures are taken to preclude fish from utilizing thescreen/pump well areas during pump shut down and start up.

This document presents a summarized report for the Fish Population Study performed on the 47acre Essential Cooling Pond (ECP) at the South Texas Project Electric Generating Station(STPEGS), Wadsworth, Texas. The objective of this study was to determine baselinecharacteristics of the fish population (Nekton Population) in the 47 acre ECP and to providemanagement recommendations for monitoring and controlling said fish population. Section 1presents the materials and methods arranged categorically. Section 2 discusses the datacollected. Section 3 presents a discussion of the results and provides managementrecommendations.1.1 MATERIALS AND METHODSThe fish population study was conducted in accordance with techniques described inFISHERIES TECHNIQUES by Nielson and Johnson (1983), published by the AmericanFisheries Society.The ECP was divided into four quadrants (Q1, Q2, Q3, Q4) based on linear shorelinemeasurements of approximately 1000 feet (Figure 1). Each quadrant was divided into twoapproximately equal sections and labeled as section A or B for each quadrant starting in aclockwise direction from the discharge structure around to the intake structure. A total of eightsections were identified in the ECP. A GARMIN 48 handheld GPS unit was used to verifysample quadrants and sections. Latitude and longitude coordinates were recorded for allsamples collected. Per the request of site management (Pre-Job Brief) no gill nets or hoop netswere set within 1000 feet of the intake structure. Gill net and hoop net sets designated for Q4were set on or immediately adjacent to the 1000-foot line in Q3 (Figure 2).

These data included pH and conductivity. Conductivitywas converted to salinity [parts per thousand (ppt)] using a conversion nomogram. Hydrologicaldata collected during this study were used only as base-line reference points for currentconditions in the ECP.1.3 NEKTONThe following gear types were used to establish sample size (numbers) and species (kinds) of fishpresent in the ECP. These gear types are routinely used by fisheries biologists for conductingtotal fish population assessments.Trawl samples were collected in the ECP using a 6.1 m (20 ft) otter trawl measured along thehead-rope from shackle to shackle. A trawl door measuring 1.2 m long and 0.6 m tall (48 inch x21 inch) was attached to each wing of the net. Each door was shackled to a 30.4-m (100 ft) longbridal and then attached to the stern of the towing vessel. The trawl was comprised of 3.8-cm (13/8-inch) stretched-nylon mesh and the cod end of the trawl was covered by a 6.3-mm (1/4 inch)nylon mesh sock. Trawl samples were towed for ten minutes behind a 16-foot center-consoleboat powered by a 40 hp motor. In the initial work scope, tow speed was set at 3.0 knots for allsamples; however, trawls were towed at approximately 2.0 knots in an effort to minimize netavoidance caused by engine prop wash. A total of eight trawl samples were collected (2 per eachQuadrant). All finfish species were measured for total length (TL) to the nearest mm. If more than50 individuals of a species occurred in sample, a random subsample of 50 was measured and theremaining individuals were counted to obtain a total number for each species.UD~ CI'tAJO~Q I rcuors~,I r~JIJut4utJ,, oiuuy 2 tviay ctnJc057 7- -F -O rEl/isl rpuI~u oln i u iy2Maey =w Gill net samples were collected in the ECP using four (4) experimental gill nets constructed ofmonofilament mesh.

Two 15-lb concrete blocks were used toanchor each gill net to the bottom and one 15-lb block was used to anchor each gill net on theshore. Gill nets were set in randomly selected sections within each quadrant. Quadrant 4 gillnet was set on or immediately adjacent to the 1000-foot boundary line separating Quadrant 3and Quadrant 4 (the net was essentially set in Quadrant 3) per the Pre-Job Brief requirementthat no nets be set within 1000 ft of the intake structure. Gill nets were set starting shortlybefore sunset (6:18 pm) and were retrieved within 2 hours after sunrise (6:38 am) on thefollowing morning. No fish were captured in any of the gill net sets. Had fish been captured inthe gill nets, they would have been sorted according to each section of mesh, identified byspecies, and measured for TL to the nearest millimeter.Four hoop net samples were set in the ECP using hoop nets constructed of fiberglass rings and cottonnetting material. Each net measured 3.6-m (12-ft) in length, had an opening hoop diameter of 0.91--m(3-ft), and was covered by 5.1-cm (2-inch) stretched cotton mesh netting dipped in nylon coating.Hoop nets were set in a randomly selected section within each quadrant.

Each net was baited with a fish attractant (one can of dog food,recommended by local commercial fishermen). Hoop nets were set with the opening facing downcurrent, anchored by two 15-lb concrete blocks and marked with buoys for easy retrieval. No fish werecaptured in any of the hoop net sets. Had fish been captured in the hoop nets, they would have beensorted by species and measured for TL to the nearest millimeter.1.4 DATA ANALYSISData analysis was conducted for eight trawl samples and included the following parameters:total number of fish for each species captured, calculation of average size and range of sizes foreach species, cumulative length frequencies for each species, and an estimate of relativeabundance for each species.U572/-0t-UU/: IH'tU6:/F-ISn Population Study3 Relative abundance was calculated by dividing the total number of each species captured bythe amount of effort (time) the gear was used.

Latitude and longitudecoordinates for each sample site are presented in Table 1. A total of 16 samples were collectedduring this study. Hydrological and nekton data are presented below.2.2 HYDROLOGICAL DATAHydrological data (water temperature, dissolved oxygen, salinity, and pH) are presented inTable 2.Water temperature during the study was 20.5 'C at the start of the study and 20.4 °C at thecompletion of the study.Dissolved oxygen (DO) readings during the study period ranged from 7.8 mg/I to 9.8 mg/I. DOreadings were the highest in Quadrant 1 and the lowest in Quadrant 4. DO readings decreasedincrementally from quadrant to quadrant as the sample stations moved further away from thedischarge structure. This is to be expected, based on the turbulence near the discharge servingas an aerator. Dissolved oxygen readings were higher on day 1 than day 2 for all samplestations. Lowest dissolved oxygen readings were recorded on the second day of the study duringthe retrieval of the gill nets and hoop nets. A reading of 7.8 mg/I was recorded at Q4. Quadrant 1dissolved oxygen readings on day 2 dropped down to 8.0 mg/l.STPEGS' Project Manager provided additional water quality data. Their data during the studyperiod indicated the pH to range from 8.87 to 8.89 and conductivity to be 1114 qS/cm to 1131.qS/cm. Conversion of conductivity readings to salinity parts per thousand (ppt) indicated thatsalinity was <2.0 ppt. Additional water quality data provided by STPEGS'sChemistry/Environmental personnel indicated that pH in the ECP has fluctuated between 8.3 and9.5 since November 1999 (Appendix A).UOICt~tAJOIOI rcuoIrIbII rupumirurr otuuy 5 gv~y ~uueU5727-ýSII Ipu atiUI on U y5M~ay 2002, 2.3 NEKTONA total of 5,589 fish representing 2 species was caught during this study (Table 3). Speciescollected during sampling were Cyprinodon variegatus, (Sheepshead minnow) and Poecilialatipinna, (Sailfin molly). The trawl was the only gear type to capture fish. A discussion of eachsampling gear is detailed below.2.3.1 TrawlsA total of eight (8) trawl samples-were collected on the 47 acre ECP. Trawl samples werecollected from eight different sections (Q1A, Q1 B, Q2A, Q2B, Q3A, Q3B, Q4A, and Q4B) of theECP (Figure 2). Each section was trawled for 10 minutes at a tow speed of 2 knots. However,trawl sample Q4A was trawled for 8 minutes due to a twist in the trawl door that occurred duringsampling. No attempt was made to redo the sample due to the proximity to the intake structure(within 1000 ft) and because the area was already covered during the initial trawl samplecollection. Trawling twice in the same sample area during the same sample period could resultin even fewer fish being caught. CPUE was adjusted according to different trawl times. A two-sample t-statistic was run to test for difference in sample population means between Q4A andQ4B. T-statistic results indicated there was no significant (95% level) difference between thetwo sample population means; further indicating there was no bias introduced by the shortenedtrawl time.Total catch (by number and catch rate) for each section is presented in Table 3. Section Q2Ahad the largest number of fish captured of all sections sampled. Section Q1 B had the fewestnumber of fish captured. ANOVA test results across all eight samples indicated that there wasno significant (95% level) difference between sample means, thus indicating that all eight trawlsamples were homogeneous.Total fish caught by quadrant indicates a significantly lower number of fish were caught in Q1 ascompared to the other three quadrants. However, the total number of fish caught in Q2, Q3, andQ4 were not significantly different from one another.UO~~t-LflJN~I rtu~,rwfI ropuwtivri otutiy 6 May ~UU~-opu t~onl ou y6may 2002=: | ||
Catch rates for each section and quadrant are listed in Table 4. Catch rates by speciesindicates that sheepshead minnows were most prevalent in section Q2A and least abundant inQ1B. Sailfin mollies were most prevalent in section Q4A and least abundant in sections QIA,Q1 B, and Q3A. Species relative abundance was most evenly distributed across Q2 and Q3.The abundance of sailfin mollies in Q4 can be attributed to a number of different components;however, the availability of food and habitat (structure) as it relates to the intake structure aremost likely the key components. Mean sizes for both species were the same across all samplesections (Table 5). The widest range was for sailfin mollies, which ranged from 27 to 62 mm TL(1 inch to 2.5 inches). The abundance of sailfin mollies was most prevalent in the 40 to 55 mmTL (1.5 to 2.25 inches) size class. Cumulative length frequencies for both species arepresented in Figures 3 and 4.2.3.2 Gill NetsFour experimental gill nets were set in the ECP; one net per quadrant in randomly selectedsections of each quadrant. No fish were captured in any of the gill net samples. Gill net fishingtimes (effort) are listed in Table 6. Average fishing time for gill nets was 13.24 hours.2.3.3 Hoop NetsFour hoop nets were set in the ECP; one net per quadrant in randomly selected sections of eachquadrant. No fish were captured in any of the hoop net samples. Hoop net fishing times (effort)are listed in Table 6. Average fishing time for hoop nets was 14.01 hours.u~LeI-LAJ~ I rtu~irisn rupui~uun ~iuuy 7 IVIdY CUUC05727-00/1 IE~is opulatton Sludy7Maliy 2LqJ EKr RNITA.3.0 DISCUSSIONDiscussions of the results for our study and management recommendations are detailed below.3.1 RESULTSHydrological data were collected during this study for the purpose of establishing baseline waterquality parameters in the ECP. No statistical correlation between fish abundance and waterquality was performed using these data. Any inferences concerning possible correlation wouldbe speculative at best and would require more data.Trawling was the only successful method of capturing fish in the ECP. Trawl samples collectedin each of the four quadrants contained fish. Although only two species were captured, the totalnumber and catch rate for each species indicates these fish are prevalent in all areas of theECP. Quadrant 1 was the only quadrant sampled which had a significant difference in totalnumber of fish. This fact can most likely be attributed to the amount of water being dischargedby the plant into quadrant 1 of the ECP. Despite the fact that most fish species are attracted towater currents, flow rates from the discharge structure into Quadrant 1 are judged to be highenough to discourage most fish from residing in this area, specifically smaller fish such as thosecollected in our samples. In fact, it may be great enough to flush them from the area or limittheir presence to the perimeter of the pond. A similar difference in distribution could beexpected directly in front of the intake structure. However, it would be impossible to discernwhere exactly the fish in our study were caught because trawling methods used covered bothshoreline and open water areas. Furthermore, trawl samples were not collected immediately infront of the intake structure for safety reasons.Data from the four gill net and four hoop net samples indicate the absence of larger fish speciesin the ECP. Although it is possible the sampling gears may have been selective for species andsizes, it is highly unlikely that all eight samples would have resulted in zero catches if fish of anysize over 3 inches were present in the ECP. Furthermore, the lack of species diversity collectedduring trawl samples indicates no other species were present in the pond. Trawling is typicallyselective for the size of the individual captured, but not selective for species.-~a -C.JUC0512 -0viyo I s PoL/InFpulaionl~ oudy8May 2002 EKR.The lack of species diversity has been further validated by data collected by STPEGS sitepersonnel. Their preliminary data indicated that only sheepshead minnows and sailfin mollieswere the species present (Appendix B). Their data were collected using baited minnow traps ator near the intake structure and the discharge structure. Comparative analysis of catch ratesbetween gears is very difficult. Although no direct correlation between STPEGS data and thedata we collected was conducted, the use of minnow traps to collect data as it pertains torelative abundance, size distribution, and species composition could prove valuable assumingproper sampling techniques are followed. These would include standardizing sample stations,sample times (soak time), placement depths, and baiting techniques to name a few.Data analysis of the eight trawl samples indicated the fish populations sampled werehomogeneous. Mean sizes of fish captured in all four quadrants were similar for both species.Data analysis of sample size and catch rates indicate that Q1 was significantly different fromQ2, Q3, and Q4. This significant difference can most likely be attributed to the velocity water inQI. Total abundance of fish was determined based on total number of fish caught andestimates of area covered during trawl samples.In an effort to estimate the total number of fish in the ECP, we made several basic assumptions,the validity of which we cannot verify based on a single set of samples. We have taken a "worstcase" approach, which could overestimate the actual population size.We have assumed that there is a uniform distribution of fish throughout the ECP, both in depthand in width. We have also assumed that our trawling effort covered 5% of the total watervolume and caught all fish that encountered the gear. Therefore, we collected 5% of the totalpopulation during our sampling effort. Based on these assumptions and extrapolation of thedata, there is a population of 535,000 fish in the ECP, comprised of both species. However, weknow that the fish are not uniformly distributed (Q1 was statistically different than Q2, Q3, Q4 inour data) and the size of the area sampled was not precisely 5% of the total area.Consequently, the actual population size could be less than this. As both species are morecommonly found in shallow water or shoreline areas rather than open- or deep-water areas, it ishighly probable that fish collected in the trawls were captured only from the shoreline zones. Ifs opua on u9,vay this is true, the total population would be expected to be less than what we estimated, as theestimate is based on the total volume, not just the shallow shoreline area. Having determinedthat this is likely the case, we do not feel that either species is overpopulated.Congregation of these species at or near the intake structure may be attributed to the availabilityof food, structure or cover, and protection from environmental stresses such as extensive coldspells. During normal environmental conditions, fish in the ECP should tend to seek out naturalhabitats or niches. The occurrence of fish in the intake wells during cold weather conditions is anatural response. Fish will seek protected waters that provide relief from existing environmentalconditions. The intake structure could provide such habitat. This could be particularly truewhen pumps are shutdown, creating a calm water refuge in the screen/pump wells. If this infact happens, one would expect an increase in impingement when pumps are turned back on.Under normal operating and environmental conditions, both species would be expected to avoidthe higher water velocities found immediately adjacent to the intake structure. Therefore, webelieve that excessive impingement could occur only when pumps are shut down for anextended time period and fish either seek shelter within the intake structure pump wells, orutilize it as new habitat due to additional food availability and/or cover. Preventing fish fromcongregating in the intake structures may be achieved by maintaining a constant flow ratethrough the screens and/or by changing the chemical composition of the water around thepumps. This may be accomplished by dispersing chemicals, such as rotenone, chlorine, orother chemicals, directly into the water in the pump wells prior to restarting of pumps.The species captured from the ECP, Cyprinodon variegatus (sheepshead minnow) and Poecilialatipinna (sailfin molly) are common to brackish waters of the Texas Gulf Coast and bothspecies are found in the many rivers and streams that enter the Texas bays. Make-up water forthe ECP was from the main cooling reservoir, which originally came from the adjacent ColoradoRiver. Both species are common in this river system (Texas Parks and Wildlife, personalcommunication).Although the possible sources of these fish were not evaluated in this study, ENSR is of theopinion that fish were introduced during the initial filling of the ECP. This means of introduction05127-0=6/ I Ftt;:gw-Sn' Hopulation Zjtucly10may 2002 is highly probable if surface water was used to fill the pond. In the case of the sheepsheadminnow, eggs could have also been carried in on the feet, legs, and plumage of various wadingand aquatic birds as their eggs are semi-adhesive and are capable of adhering to thesesurfaces. This mechanism of introduction is not deemed possible with sailfin mollies.Of the two species captured, sheepshead minnows were more prevalent by a ratio of 50:1.Mean sizes of both species caught in the ECP were within normal length ranges and themajority of fish were either subadult or adults. Maximum length for sheepshead minnows was55 mm TL (2.25 inches) and the maximum length for sailfin mollies was 62 mm TL (2.6 inches).No fish less than 20 mm TL were caught. The lack of juvenile fish in the samples is most likelya result of mesh size used on the trawl. A smaller mesh size would need to be used to capturethe juvenile fish.Sheepshead minnows are a very hardy species. They are tolerable of a wide range of waterquality conditions and are commonly found in marine, brackish, and freshwater habitats. Theyprefer shallow water habitats and are most common along sandy or silty shorelines.Sheepshead minnows can reach a maximum size of 3 inches and have an average life span ofabout three years. They are very prolific breeders reaching sexual maturity by the time they areone year old. They are egg layers and will spawn multiple times during the spring and summermonths allowing them to populate an area in a very short period of time. They will layapproximately 20-25 eggs per spawn and their eggs are semi-adhesive. Sheepshead minnowsare detritivores and prefer to feed over substrates of silt and detritus. They are known to burrowinto soft substrate during adverse conditions, such as large temperature fluctuations andextreme tidal changes; which enables them to survive these situations.Sailfin mollies are primarily a brackish water species. They are known to be very adaptable inthe wild and are commonly found in freshwater rivers and streams as well as saltwaterenvironments. They feed mostly on algae and other plant matter that is available. Sailfinmollies are surface dwelling and swim freely in open areas, and they are particular to watersthat are high in calcium (hard water) and more alkaline waters ranging in pH from 7.5 to 8.5.Sailfin mollies are typically 4 to 6 inches in length and have an average life span of 3 years.Po ulation StuA, Ma 2002F1"1 ENsRThey are live bearers, giving birth to 20 to 80 fully developed young in each brood. The femalesailfin molly will give birth once every six to eight weeks during the breeding season (April toSeptember). They can produce young year round; however, they normally do not give birthwhen water temperatures are below 21.1°C.Beneficial aspects of these fish species in the ECP were not evaluated during our study.However, both species are known to feed on algae as well as other plant matter such as detritusand therefore could have a positive impact on the ECP. Furthermore, the ability of these fish tomaintain healthy populations in the ECP is a good indication that the present ecosystem isproviding necessary food, habitat, and water quality. It should be noted however, that currentturbidity levels in the ECP are too high to allow establishment of large quantities of algaethroughout the entire pond. Most of the algae should be isolated along the shoreline whereavailable sunlight can penetrate the water and allow algae to grow. It is our opinion that if algaelevels were to get to problematic levels in the ECP, it would require a larger population than thecurrent population of fish to alleviate the problem.3.2 MANAGEMENT RECOMMENDATIONSManagement of undesirable fish populations is achieved by using three basic methods:chemical, biological, and mechanical. Chemical and biological means are favored overmechanical controls for most species of fishes (Kohler and Hubert, 1993). Before determiningwhat management approach will be most effective, several factors should be considered andevaluated. These include cost, size of the water body, water temperature and quality, targetspecies, environmental concerns, and location of the water body (Kohler and Hubert, 1993).The use of chemical methods to control undesirable fish populations has become a very populartool for fisheries managers. Most chemicals are easily applied, require a short time to getresults, and very inexpensive when compared to other methods. Chemical methods aretypically used to treat an entire system where the goal is the removal of all fish. Chemicals canalso be used to partially treat particular sections, or spawning sites of selected fishes in an effortU~727-COWi I PL(~S/HSfl I~opuIation ~tudy 12 May ~UO205727-008/Zi 1 PE(35/I-I$1 Population 12may z200 EN, .to remove a major portion of the population. This approach usually requires the introduction ofa predatory species to forage on the remaining residual population.Chemicals used as fish toxicants must meet the needs* of the fishery managers. The toxicantshould be specific for the targeted species, easy and safe to apply, degrade to a harmlessconstituent, must be effective over a broad range of water quality conditions, and be registeredfor use in the aquatic environment (Lennon et al. 1970).There are four approved and registered toxicants in the United States, two of which areregistered for "general" use and will be discussed; rotenone and Antimycin. Fisheries managerscommonly use both of these toxicants.Rotenone is the most common fish toxicant used by fisheries managers. Rotenone works byshutting down the oxygen transfer system in fish, which eventually causes suffocation. Thechemical is safe and effective when applied properly and has almost no adverse affect on birdsor mammals. Rotenone comes in liquid and powder formulations and can be dispersed byvarious methods. Liquid forms are easier to handle; however, they work best in shallower lakesand ponds. Rotenone is usually applied in the summer or fall when the water temperatures areabove 20'C. There are several factors that affect the toxicity of rotenone; water temperature,light, dissolved oxygen, turbidity, and alkalinity. Some species of fish can tolerate low levels ofoxygen and are therefore less susceptible to the effects of rotenone.Antimycin is an antibiotic and is the only other chemical registered as a "general" fish toxicant(Kohler and Hubert 1993). It is available only in a liquid form and is not as effective in deeperlakes. Antimycin is commonly referred to as Fintrol; however, it is not a common product foundon the market. Antimycin is most effective in lakes, ponds, and streams that are comprised of asoft-water chemistry.n.10ý 0 1 -i stuý, M -02op vsuau 13jay IKRIBiological methods used to control undesirable fish species include the use of predation byother species of fish, birds, mammals, etc. It also includes the use of pathogens andbiomanipulation to achieve the desired ecological balance. The use of biological methodsusually requires adding one or more biological mechanism(s) into the natural system. Addingnew species or managing for a particular species to control an undesirable species can haveadverse effects on the overall management goals. Before choosing this approach, fisheriesmanagers must evaluate whether the predator-prey combination will be effective as a controlagent. Biological control methods are less expensive than chemical methods; however, thedesired result is not attained as rapidly as with chemical methods, but often it is a morepermanent method.Mechanical methods used to control undesirable fish species include water level manipulation,traps, barriers, commercial fishing, and electricity. Other methods include seines, trawls, gillnets, and cast nets. All of these gears are labor intensive and require multiple applications overan extended period of time to have an overall impact on the fishery.Complete eradication of undesirable fish species is seldom possible. However, control of existingspecies can be achieved by using methods that are applied at a time and location when theundesirable species is most vulnerable. The use of an integrated management approach mayprove to be more effective than any one single approach.Based on the fish species present and the present population structure, management of thesespecies may be best achieved by utilizing a combination of management approaches. Somepossible approaches could include the following:* Complete removal of both species through the use of chemicals such as Rotenone;* Management of species using both mechanical and chemical methods such as trawls,seining, and traps, followed by supplemental Rotenone applications;* Management of species using mechanical methods described and supplemented by stockingof predator species; and* Management of species using only mechanical methods.U3,C-~AOOrcurisi rpuiwuiiowuyIV~Y CUC 15U 7-00/-JIoI Po'pulation Study14auy -'u All things considered, total removal of all fish from the Essential Cooling Pond may not bepossible and or desirable due to beneficial aspects such as algae control. Using chemicals canbe quite costly and will most likely not kill all the fish in the pond. Remaining individuals would beable to repopulate the pond in time. Furthermore, a massive kill could require a considerableamount of manpower and there is the possibility that dead fish would clog the screens at theintake structure.Managing the species using multiple methods may prove most beneficial. First, capture of the fishusing trawls or other gear will provide continuing data on the productivity of the fish population.Second, the cost associated with sampling will not be as high. Third, sampling could take placeduring times of the year when fish populations are the highest and pose the greatest threat to thepumps. For example, changes in numbers or species distribution detected in minnow traps couldbe used to implement control methodology. Fourth, supplementing the sampling with heavydosages of rotenone in specific areas of the lake during peak spawning periods and before orduring the coldest winter months could help manage the populations. An additional approachincludes managing the pond by having a commercial fisherman harvest the two fish species.Both species are popular on the tropical fish market and/or are used by commercial laboratoriesfor toxicity testing.The use of biological methods does work in some well managed lakes and ponds. However, theuse of a biological control in the ECP would require continued management of stocked predatorspecies and could eventually become a management problem in and of itself in the future.Given the dynamics of the ECP and the species present, managing the fish population will requirean established monitoring and control plan based on the recommendations above. Periodicmonitoring of the fish population in the pond should be used to determine if any controlmethodology is required based on plant operational considerations. For example, quarterlysampling using minnow traps with a standardized sampling program would provide size andspecies distribution information that could serve as a basis for initiating additional actions.Jug C, tJv0,c, r~~orICI H FUWUHGIIUI H CtUU~Uol~ ~ ~~ op a, lliFVInU Ituy15ay S:~RIn an effort to prevent impingement after extended periods when a pump may be shut down, it isrecommended that chemicals could be applied to the screen/pump wells prior to shut down toexclude or eliminate fish. Additionally, the placement of stop logs in the intake structure shouldhelp to preclude fish from utilizing the screen/pump wells during the down periods. | Catch rates for each section and quadrant are listed in Table 4. Catch rates by speciesindicates that sheepshead minnows were most prevalent in section Q2A and least abundant inQ1B. Sailfin mollies were most prevalent in section Q4A and least abundant in sections QIA,Q1 B, and Q3A. Species relative abundance was most evenly distributed across Q2 and Q3.The abundance of sailfin mollies in Q4 can be attributed to a number of different components;however, the availability of food and habitat (structure) as it relates to the intake structure aremost likely the key components. Mean sizes for both species were the same across all samplesections (Table 5). The widest range was for sailfin mollies, which ranged from 27 to 62 mm TL(1 inch to 2.5 inches). The abundance of sailfin mollies was most prevalent in the 40 to 55 mmTL (1.5 to 2.25 inches) size class. Cumulative length frequencies for both species arepresented in Figures 3 and 4.2.3.2 Gill NetsFour experimental gill nets were set in the ECP; one net per quadrant in randomly selectedsections of each quadrant. No fish were captured in any of the gill net samples. Gill net fishingtimes (effort) are listed in Table 6. Average fishing time for gill nets was 13.24 hours.2.3.3 Hoop NetsFour hoop nets were set in the ECP; one net per quadrant in randomly selected sections of eachquadrant. No fish were captured in any of the hoop net samples. Hoop net fishing times (effort)are listed in Table 6. Average fishing time for hoop nets was 14.01 hours.u~LeI-LAJ~ I rtu~irisn rupui~uun ~iuuy 7 IVIdY CUUC05727-00/1 IE~is opulatton Sludy7Maliy 2LqJ EKr RNITA.3.0 DISCUSSIONDiscussions of the results for our study and management recommendations are detailed below.3.1 RESULTSHydrological data were collected during this study for the purpose of establishing baseline waterquality parameters in the ECP. No statistical correlation between fish abundance and waterquality was performed using these data. Any inferences concerning possible correlation wouldbe speculative at best and would require more data.Trawling was the only successful method of capturing fish in the ECP. Trawl samples collectedin each of the four quadrants contained fish. Although only two species were captured, the totalnumber and catch rate for each species indicates these fish are prevalent in all areas of theECP. Quadrant 1 was the only quadrant sampled which had a significant difference in totalnumber of fish. This fact can most likely be attributed to the amount of water being dischargedby the plant into quadrant 1 of the ECP. Despite the fact that most fish species are attracted towater currents, flow rates from the discharge structure into Quadrant 1 are judged to be highenough to discourage most fish from residing in this area, specifically smaller fish such as thosecollected in our samples. In fact, it may be great enough to flush them from the area or limittheir presence to the perimeter of the pond. A similar difference in distribution could beexpected directly in front of the intake structure. However, it would be impossible to discernwhere exactly the fish in our study were caught because trawling methods used covered bothshoreline and open water areas. Furthermore, trawl samples were not collected immediately infront of the intake structure for safety reasons.Data from the four gill net and four hoop net samples indicate the absence of larger fish speciesin the ECP. Although it is possible the sampling gears may have been selective for species andsizes, it is highly unlikely that all eight samples would have resulted in zero catches if fish of anysize over 3 inches were present in the ECP. Furthermore, the lack of species diversity collectedduring trawl samples indicates no other species were present in the pond. Trawling is typicallyselective for the size of the individual captured, but not selective for species.-~a -C.JUC0512 -0viyo I s PoL/InFpulaionl~ oudy8May 2002 EKR.The lack of species diversity has been further validated by data collected by STPEGS sitepersonnel. Their preliminary data indicated that only sheepshead minnows and sailfin mollieswere the species present (Appendix B). Their data were collected using baited minnow traps ator near the intake structure and the discharge structure. Comparative analysis of catch ratesbetween gears is very difficult. Although no direct correlation between STPEGS data and thedata we collected was conducted, the use of minnow traps to collect data as it pertains torelative abundance, size distribution, and species composition could prove valuable assumingproper sampling techniques are followed. These would include standardizing sample stations,sample times (soak time), placement depths, and baiting techniques to name a few.Data analysis of the eight trawl samples indicated the fish populations sampled werehomogeneous. Mean sizes of fish captured in all four quadrants were similar for both species.Data analysis of sample size and catch rates indicate that Q1 was significantly different fromQ2, Q3, and Q4. This significant difference can most likely be attributed to the velocity water inQI. Total abundance of fish was determined based on total number of fish caught andestimates of area covered during trawl samples.In an effort to estimate the total number of fish in the ECP, we made several basic assumptions,the validity of which we cannot verify based on a single set of samples. We have taken a "worstcase" approach, which could overestimate the actual population size.We have assumed that there is a uniform distribution of fish throughout the ECP, both in depthand in width. We have also assumed that our trawling effort covered 5% of the total watervolume and caught all fish that encountered the gear. Therefore, we collected 5% of the totalpopulation during our sampling effort. Based on these assumptions and extrapolation of thedata, there is a population of 535,000 fish in the ECP, comprised of both species. However, weknow that the fish are not uniformly distributed (Q1 was statistically different than Q2, Q3, Q4 inour data) and the size of the area sampled was not precisely 5% of the total area.Consequently, the actual population size could be less than this. As both species are morecommonly found in shallow water or shoreline areas rather than open- or deep-water areas, it ishighly probable that fish collected in the trawls were captured only from the shoreline zones. Ifs opua on u9,vay this is true, the total population would be expected to be less than what we estimated, as theestimate is based on the total volume, not just the shallow shoreline area. Having determinedthat this is likely the case, we do not feel that either species is overpopulated.Congregation of these species at or near the intake structure may be attributed to the availabilityof food, structure or cover, and protection from environmental stresses such as extensive coldspells. During normal environmental conditions, fish in the ECP should tend to seek out naturalhabitats or niches. The occurrence of fish in the intake wells during cold weather conditions is anatural response. Fish will seek protected waters that provide relief from existing environmentalconditions. The intake structure could provide such habitat. This could be particularly truewhen pumps are shutdown, creating a calm water refuge in the screen/pump wells. If this infact happens, one would expect an increase in impingement when pumps are turned back on.Under normal operating and environmental conditions, both species would be expected to avoidthe higher water velocities found immediately adjacent to the intake structure. Therefore, webelieve that excessive impingement could occur only when pumps are shut down for anextended time period and fish either seek shelter within the intake structure pump wells, orutilize it as new habitat due to additional food availability and/or cover. Preventing fish fromcongregating in the intake structures may be achieved by maintaining a constant flow ratethrough the screens and/or by changing the chemical composition of the water around thepumps. This may be accomplished by dispersing chemicals, such as rotenone, chlorine, orother chemicals, directly into the water in the pump wells prior to restarting of pumps.The species captured from the ECP, Cyprinodon variegatus (sheepshead minnow) and Poecilialatipinna (sailfin molly) are common to brackish waters of the Texas Gulf Coast and bothspecies are found in the many rivers and streams that enter the Texas bays. Make-up water forthe ECP was from the main cooling reservoir, which originally came from the adjacent ColoradoRiver. Both species are common in this river system (Texas Parks and Wildlife, personalcommunication).Although the possible sources of these fish were not evaluated in this study, ENSR is of theopinion that fish were introduced during the initial filling of the ECP. This means of introduction05127-0=6/ I Ftt;:gw-Sn' Hopulation Zjtucly10may 2002 is highly probable if surface water was used to fill the pond. In the case of the sheepsheadminnow, eggs could have also been carried in on the feet, legs, and plumage of various wadingand aquatic birds as their eggs are semi-adhesive and are capable of adhering to thesesurfaces. This mechanism of introduction is not deemed possible with sailfin mollies.Of the two species captured, sheepshead minnows were more prevalent by a ratio of 50:1.Mean sizes of both species caught in the ECP were within normal length ranges and themajority of fish were either subadult or adults. Maximum length for sheepshead minnows was55 mm TL (2.25 inches) and the maximum length for sailfin mollies was 62 mm TL (2.6 inches).No fish less than 20 mm TL were caught. The lack of juvenile fish in the samples is most likelya result of mesh size used on the trawl. A smaller mesh size would need to be used to capturethe juvenile fish.Sheepshead minnows are a very hardy species. They are tolerable of a wide range of waterquality conditions and are commonly found in marine, brackish, and freshwater habitats. Theyprefer shallow water habitats and are most common along sandy or silty shorelines.Sheepshead minnows can reach a maximum size of 3 inches and have an average life span ofabout three years. They are very prolific breeders reaching sexual maturity by the time they areone year old. They are egg layers and will spawn multiple times during the spring and summermonths allowing them to populate an area in a very short period of time. They will layapproximately 20-25 eggs per spawn and their eggs are semi-adhesive. Sheepshead minnowsare detritivores and prefer to feed over substrates of silt and detritus. They are known to burrowinto soft substrate during adverse conditions, such as large temperature fluctuations andextreme tidal changes; which enables them to survive these situations.Sailfin mollies are primarily a brackish water species. They are known to be very adaptable inthe wild and are commonly found in freshwater rivers and streams as well as saltwaterenvironments. They feed mostly on algae and other plant matter that is available. Sailfinmollies are surface dwelling and swim freely in open areas, and they are particular to watersthat are high in calcium (hard water) and more alkaline waters ranging in pH from 7.5 to 8.5.Sailfin mollies are typically 4 to 6 inches in length and have an average life span of 3 years.Po ulation StuA, Ma 2002F1"1 ENsRThey are live bearers, giving birth to 20 to 80 fully developed young in each brood. The femalesailfin molly will give birth once every six to eight weeks during the breeding season (April toSeptember). They can produce young year round; however, they normally do not give birthwhen water temperatures are below 21.1°C.Beneficial aspects of these fish species in the ECP were not evaluated during our study.However, both species are known to feed on algae as well as other plant matter such as detritusand therefore could have a positive impact on the ECP. Furthermore, the ability of these fish tomaintain healthy populations in the ECP is a good indication that the present ecosystem isproviding necessary food, habitat, and water quality.

However, we have reviewedthe information you submitted and based on our best professional judgement, we consider your facility tobe a closed-cycle recirculating system. As mentioned in your letter, the federal rule governing the 316(b)Phase I1 cooling water intakes is currently in the process of being suspended.

==Dear Mr. Gangluff:== | |||
I received your letter dated May 24, 2007, requesting that the Main Cooling Reservoir (MCR) bedesignated as a closed-cycle recirculating system and as not water in the state.The Texas Commission on Environmental Quality (TCEQ) does not have an official method of"designating" a facility's operation as a closed-cycle recirculating system. However, we have reviewedthe information you submitted and based on our best professional judgement, we consider your facility tobe a closed-cycle recirculating system. As mentioned in your letter, the federal rule governing the 316(b)Phase I1 cooling water intakes is currently in the process of being suspended. For the time being,implementation of the 316(b) requirements will be based on best professional judgement (BPJ) andsubject to EPA Region VI review.We also concur that the Main Cooling Reservoir (MCR) at your facility does not meet the definition ofwater in the state.If you have any questions, please contact me at (512) 239-2369.Sincerely,Kelly Ilolligan, LeaderIndustrial TeamWater Quality DivisionKH!jpP.O.

The operational studies involve a continuationof procedures established during construction phase monitoring,which covered the period 1978-1987.Species selected for monitoring were considered to beindicators of general environmental quality. Both Americanalligators (Alligator mississippiensis) and bald eagles(Haliaeetus leucocephalus) were originally chosen because oftheir endangered and threatened species status. Since the studywas initiated the status of the American alligator in Texas hasbeen changed from endangered to threatened by similarity ofappearance (Federal Register 1983). Other species selected formonitoring were white-tailed deer (Odocoileus virginianus) andwaterfowl (family Anatidae) because of their recreational andeconomic importance to the region. Selected resident waterfowland shorebirds were also monitored for changes in populations.Presented in this report are the results of fieldinvestigations conducted on and near the STP site betweenSeptember 1987 and May 1988. These data are summarized andcompared with data obtained in earlier years (1978-1987). Theresults of studies conducted in previous years were reported bySpringer (1980), Leavens et al. (1981), Davis (1952, 1983), Davisand Wilkinson (1984), Greene et al. (1985), Baker et al. (1986),Greene et al. (1987), and Baker and Greene (1988).STUDY AREAThe STP site is located in southern Matagorda County,approximately 16 km south of Bay City, on the west bank of theColorado River (Figure 1). Over half of the 5000 ha site isoccupied by a cooling reservoir which presently has an averagedepth of about 3.5 m.Vegetationally, the study area is part of the Gulf Prariesand Marshes region (Gould 1975). Five basic wildlife habitatshave been identified on the site: (1) the disturbed constructionarea, (2) the cooling reservoir, (3) the woodlands between thereservoir and the Colorado River, (4) drainage and irrigationcanals, and (5) Kelly Lake.1 I ý'OKLAHOMAI68ýww M0,00Art0tRa~EIC OrtF -& | .1987 -1988SPECIAL ECOLOGICAL STUDIES FOR THE SOUTH TEXAS PROJECTMATAGORDA COUNTY, TEXASFINAL REPORTbyWilliam B.

Location of the South Texas Project site METHODSAlligator SurveyAlligators at the STP site were surveyed along previouslyestablished transects. Figure 2 shows transect locations andlengths. Transects 1 and 5 (Kelly Lake and Relocated LittleRobbins Slough) were surveyed on 3 consecutive nights. Transect10 was surveyed on three consecutive days. The night surveyswere conducted no earlier than 1 hour after sunset and no laterthan 30 minutes before sunrise. All surveys were conducted on17-19 May 1988 during the dark phase of the moon (new moon).Surveys have been conducted during the dark phase of the moonsince the monitoring study began to ensure high count accuracyand to standardize the procedures (Chabreck 1966). Surveys wereconducted in May, the peak of the breeding season, whenalligators of both sexes travel a great deal and are moreconspicuous than at other times of the year (Joanen and McNease1975, Nichols et al. 1976).Transect 1 was surveyed by canoe, the other two by truck. A400,000 candlepower spotlight was used to locate the alligatorsat night. Their eyes reflect a characteristic amber glow thatcan be easily recognized and detected from several hundred yards(Chabreck 1966). With a light shining in their eyes, mostalligators will remain stationary long enough to be approachedwithin range for reliable size estimation. The alligators wereeasily approachable by truck during the day as well. Intransects 1 and 5 the alligators were assigned to size classes byestimating the distance from their eyes to the tip of theirsnout. The total body length was estimated using the formula:x = -0.5113 + 1.1456ywhere x is total length in feet and y is snout length in inches.This formula was derived by linear regression from data reportedfor coastal Louisiana alligators (Chabreck 1966). Alligatorsgreater than 1.8 m (6 ft) in length were considered adults(Nichols et al. 1976). On transect 10 (the Entire Dike), lengthestimates were made from observations of the entire animal whenvisible or from snout length when the entire animal was notvisible. The highest count for each survey period was used asthe minimum population estimate for that period.White-tailed Deer SurveyWhite-tailed deer surveys were conducted on five consecutivedays during the week of September 27-October 2, and during thefirst full week of November and December.3 | ||

Deer were observed from two fixed observation points and adriving transect between these two points. The two fixed pointswere located on the dike adjacent to the makeup right-of-way andthe blowdown canal (Figure 3). Observers watched the fixedsurvey areas for 30 minutes starting at sunrise and 30 minutesprior to sunset. Observation times for a site were rotated onalternate days, e.g., if the blowdown canal was surveyed in themorning on the first day, it would be surveyed in the evening onthe second day. The driving transect was along the western edgeof the woodlands adjacent to the reservoir. It was surveyed inthe morning and evening of each day by driving along the dikeafter each fixed survey, stopping to count and identify deer asnecessary. A 22X spotting scope was used to help classify deeraccording to age and sex. Incidental deer observations were alsorecorded while conducting waterfowl surveys.Waterfowl SurveysDucks, geese and other waterfowl are most abundant on theSTP cooling reservoir during the fall and winter months.Population estimates were made on five consecutive days duringthe week of September 27-October 2, and the first full week ofNovember and December. Observations began after the dawn deersurvey and ended before the dusk deer survey. Species wereidentified with the aid of a 22X spotting scope. The highestdaily count of each species in each month was used as the minimumpopulation estimate of that species.Additional data were obtained from the annual aerial surveysof duck and goose populations wintering in Texas, which werecoordinated by the U.S. Fish and Wildlife Service (USFWS) andconducted by the Texas Parks & Wildlife Department (TPWD). Forsurvey purposes, Texas is currently divided into five waterfowlzones by TPWD: Northeast Texas, Northwest Texas, North-centralTexas, Lower Coast and Upper Coast. Matagorda County is in theUpper Coast zone. Total goose estimates were derived fromcombined totals of Texas Coastal Goose Inventory Zones 1-3. Ducktotals were derived by combining totals in Texas Mid-winterWaterfowl Inventory Zones A,B,C, and D.Bald Eagle SurveyAll large raptors are carefully observed during waterfowlsurveys to see if they are bald eagles. In addition, reports ofbald eagle sightings in the vicinity of the STP site weresolicited from specified site personnel.5 F.'.oSITEBOUNDARYINt'COOLING RESERVOIRRESERVOIR DIKE* *OBSERVATION POINTS........ ! TRANSECT LINEWhite-tailed deer observation points and transect line on the east side ofthe STP cooling reservoir.406 An extensive aerial search for bald eagle nests in easternand coastal Texas was conducted by TPWD personnel in January,February and early March of 1988. Nests found to be active wereexamined again in March and later to determine the number ofyoung produced (Mabie 1988). When new eagle nests were located,TPWD biologists contacted landowners to acquire nest historydata.7 RESULTS AND DISCUSSIONAlligator SurveyThe maximum number of alligators observed on transects atthe STP site in 1988 was 53 (Table 1). The highest mean densityof alligators seen was 7.0 alligators/km on the Kelly Laketransect (Table 2). This represents a reduction in the densityof alligators from the 1987 census, which was apparent in all 3observation transects (Table 3). The total number of alligatorson the site continues to decline, but should begin to stabilizenow that the plant is operational, although seasonal variationsin population level will probably remain.Results of the Entire Dike survey in the Spring of 1988showed a total of 23 alligators. This represents a reduction of27 animals from the 1987 Fall survey, 7 from the 1987 Springsurvey, and 58 from the 1986 Spring survey (Table 4). Thisdecline was predicted to occur as reservoir fill operationsinundated nesting habitat in the Main Cooling Reservoir (MCR)(Baker and Greene 1988). Now that the water level is atoperational design levels the population of alligators in the MCRshould remain relatively constant, being dominated by adultmales. Based on total length estimates, the 1988 Spring surveyof the MCR showed a 98% adult population present.Results of the Kelly Lake transect indicate a maximum numberof 27 alligators. This is slightly lower than the Spring 1987survey of 32. The 1988 density in Kelly Lake was 7.0alligators/km which is well above densities recorded from1978-1985, but slightly below the density of 8.3 alligators/kmrecorded in 1987. The 1988 Kelly Lake population consisted of69% adults and 31% juveniles. Kelly Lake remains as the primealligator nesting habitat site at the STP.The Relocated Little Robbins Slough transect had a maximumcount of 3 alligators in the Spring 1988 survey, down about 50%from 1986 and 1987. This decline can probably be attributed to amajor construction project which involved dredging the entiretransect channel and resurfacing it with a layer of sand, matmaterial, and irregular shaped stone. The renovation of theSlough was completed in early 1988, just prior to the survey.Subsequent to these activities, the alligator population in theLittle Robbins Slough should stabilize. All alligators observedon this transect in 1988 Spring survey were juveniles.White-tailed Deer SurveyIn 1987 the greatest number of deer observed per day was 29,which occurred in the October survey (Table 5).

The following text includes these conditions andincorporates them into this permit. All definitions in Section 26.001 of the Texas Water Code and 30 TAC Chapter 305 shallapply to this permit and are incorporated by reference. Some specific definitions of words or phrases used in this permit areas follows:1. Flow Measurementsa. Annual average flow- the arithmetic average of all daily flow determinations taken within the preceding 12 consecutivecalendar months. The annual average flow determination shall consist of daily flow volume determinations made bya totalizing meter, charted on a chart recorder and limited to major domestic wastewater discharge facilities with a Imillion gallons per day or greater permitted flow.b. Daily average flow -the arithmetic average of-all determinations of the daily flow within a period of one calendarmonth. The daily average flow determination shall consist of determinations made on at least four separate days. Ifinstantaneous measurements are used to determine the daily flow, the determination shall be the arithmetic average ofall instantaneous measurements taken during that month. Daily average flow determination for intermittent dischargesshall consist of a minimum of three flow determinations on days of discharge.c. Daily maximum flow -the highest total flow for any 24-hour period in a calendar month.d. Instantaneous flow -the measured flow during the minimum time required to interpret the flow measuring device.e. 2-hour peak flow (domestic wastewater treatment plants) -the maximum flow sustained for a two-hour period duringthe period of daily discharge. The average of multiple measurements of instantaneous maximum flow within a two-hour period may be used to calculate the 2-hour peak flow.f. Maximum 2-hour peak flow (domestic wastewater treatment plants) -the highest 2-hour peak flow for any 24-hourperiod in a calender month.2. Concentration Measurementsa. Daily average concentration -the arithmetic average of all effluent samples, composite or grab as required by thispermit, within a period of one calendar month, consisting of at least four separate representative measurements.i. For domestic wastewater treatment plants -When four samples are not available in a calendar month, thearithmetic average (weighted by flow) of all values in the previous four consecutive month period consisting ofat least four measurements shall be utilized as the daily average concentration.ii. For all other wastewater treatment plants -When four samples are not available in a calender month, the arithmeticaverage (weighted by flow) of all values taken during the month shall be utilized as the daily averageconcentration.b. 7-day average concentration -the arithmetic average of all effluent samples, composite or grab as required by thispermit, within a period of one calendar week, Sunday through Saturday.c. Daily maximum concentration -the maximum concentration measured on a single day, by the sample type specifiedin the permit, within a period of one calender month.d. Daily discharge -the discharge of a pollutant measured during a calendar day or any 24-hour period that reasonablyrepresents the calendar day for purposes of sampling. For pollutants with limitations expressed in terms of mass, the"daily discharge" is calculated as the total mass of the pollutant discharged over the sampling day. For pollutants withlimitations expressed in other units of measurement, the "daily discharge" is calculated as the average measurementof the pollutant over the sampling day.The "daily discharge" determination of concentration made using a composite sample shall be the concentration of thecomposite sample. When grab samples are used, the "daily discharge" determination of concentration shall be thearithmetic average (weighted by flow value) of all samples collected during that day.e. Fecal coliform bacteria concentration -the number of colonies of fecal coliform bacteria per 100 milliliters effluent.The daily average fecal coliform bacteria concentration is a geometric mean of the values for the effluent samplescollected in a calendar month. The geometric mean shall be determined by calculating the nth root of the product ofall measurements made in a calender month, where n equals the number of measurements made; or, computed as thePage 2 Outfall Number 001EFFLUENT LIMITATIONS AND MONITORING REQUIREMENTS1.

The following text includes these conditions andincorporates them into this permit. All definitions in Section 26.001 of the Texas Water Code and 30 TAC Chapter 305 shallapply to this permit and are incorporated by reference. Some specific definitions of words or phrases used in this permit areas follows:1. Flow Measurementsa. Annual average flow -the arithmetic average of all daily flow determinations taken within the preceding 12 consecutivecalendar months. The annual average flow determination shall consist of daily flow volume determinations made bya totalizing meter, charted on a chart recorder and limited to major domestic wastewater discharge facilities with a Imillion gallons per day or greater permitted flow.b. Daily average- flow ý the arithmetic average of-all-determinations of-the-daily flow within a-period of-one-calendar -month. The daily average flow determination shall consist of determinations made on at least four separate days. Ifinstantaneous measurements are used to determine the daily flow, the determination shall be the arithmetic average ofall instantaneous measurements taken during that month. Daily average flow determination for intermittent dischargesshall consist of a minimum of three flow determinations on days of discharge.c. Daily maximum flow -the highest total flow for any 24-hour period in a calendar month.d. Instantaneous flow -the measured flow during the minimum time required to interpret the flow measuring device.e. 2-hour peak flow (domestic wastewater treatment plants) -the maximum flow sustained for a two-hour period duringthe period of daily discharge. The average of multiple measurements of instantaneous maximum flow within a two-hour period may be used to calculate the 2-hour peak flow.f. Maximum 2-hour peak flow (domestic wastewater treatment plants) -the highest 2-hour peak flow for any 24-hourperiod in a calender month-2. Concentration Measurementsa. Daily average concentration -the arithmetic average of all effluent samples, composite or grab as required by thispermit, within a period of one calendar month, consisting of at least four separate representative measurements.i. For domestic wastewater treatment plants -When four samples are not available in a calendar month, thearithmetic average (weighted by flow) of all values in the previous four consecutive month period consisting ofat least four measurements shall be utilized as the daily average concentration.ii. For all other wastewater treatment plants -When four samples are not available in a calender month, the arithmeticaverage (weighted by flow) of all values taken during the month shall be utilized as the daily averageconcentration.b. 7-day average concentration -the arithmetic average of all effluent samples, composite or grab as required by thispermit, within a period of one calendar week, Sunday through Saturday.c. Daily maximum concentration -the maximum concentration measured on a single day, by the sample type specifiedin the permit, within a period of one calender month.d. Daily discharge -the discharge of a pollutant measured during a calendar day or any 24-hour period that reasonablyrepresents the calendar day for purposes of sampling. For pollutants with limitations expressed in terms of mass, the"daily discharge" is calculated as the total mass of the pollutant discharged over the sampling day. For pollutants withlimitations expressed in other units of measurement, the "daily discharge" is calculated as the average measurementof the pollutant over the sampling day.The "daily discharge" determination of concentration made using a composite sample shall be the concentration of thecomposite sample. When grab samples are used, the "daily discharge" determination of concentration shall be thearithmetic average (weighted by flow'value) of all samples collected during that day.e. Fecal coliform bacteria concentration -the number of colonies of fecal coliform bacteria per 100 milliliters effluent.The daily average fecal coliform bacteria concentration is a geometric mean of the values for the effluent samplescollected in a calendar month. The geometric mean shall be determined by calculating the nth root of the product ofall measurements made in a calender month, where n equals the number of measurements made; or, computed as thePage 2 STP Nuclear Operating CompanyTPDES Permit No. WQOOO 1908000antilogarithm of the arithmetic mean of the logarithms of all measurements made in a calender month. For anymeasurement of fecal coliform bacteria equaling zero, a substituted value of one shall be made for input into eithercomputation method. The 7-day average for fecal coliform bacteria is the geometric mean of the values for all effluentsamples collected during a calender week.f. Daily average loading (lbs/day) -the arithmetic average of all daily discharge loading calculations during a period ofone calender month. These calculations must be made for each-day of the month that a parameter is analyzed. Thedaily discharge, in terms of mass (lbs/day), is calculated as ( Flow, MGD x Concentration, mg/I x 8.34).g. Daily maximum loading (lbs/day) -the highest daily discharge, in terms of mass (lbs/day), within a period of onecalender month.3. Sample Typea. Composite sample -For domestic wastewater, a composite sample is a sample made up of a minimum of three effluentportions collected in a continuous 24-hour period or during the period of daily discharge if less than 24 hours, andcombined in volumes proportional to flow, and collected at the intervals required by 30 TAC § 319.9 (a). For industrialwastewater, a composite sample is a sample made up of a minimum of three effluent portions collected in a continuous-24-hour-period-or-during-the-period of daily-discharge-if-less-than-24-hours,- and combined-in-volumesproportional toflow, and collected at the intervals required by 30 TAC § 319.9 (b).b. Grab sample -an individual sample collected in less than 15 minutes.4. Treatment Facility (facility) -wastewater facilities used in the conveyance, storage, treatment, recycling, reclamation and/ordisposal of domestic sewage, industrial wastes, agricultural wastes, recreational wastes, or other wastes including sludgehandling or disposal facilities under the jurisdiction of the Commission.5. The term "sewage sludge" is defined as solid, semi-solid, or liquid residue generated during the treatment of domesticsewage in 30 TAC Chapter 312. This includes the solids which have not been classified as hazardous waste separated fromwastewater by unit processes.6. Bypass -the intentional diversion of a waste stream from any portion of a treatment facility.MONITORING AND REPORTING REQUIREMENTS1.

The following text includes these conditions andincorporates them into this permit. All definitions in Section 26.001 of the Texas Water Code and 30 TAC Chapter 305 shallapply to this permit and are incorporated by reference. Some specific definitions of words or phrases used in this permit areas follows:1. Flow Measurementsa. Annual average flow -the arithmetic average of all daily flow determinations taken within the preceding 12 consecutivecalendar months. The annual average flow determination shall consist of daily flow volume determinations made bya totalizing meter, charted on a chart recorder and limited to major domestic wastewater discharge facilities with a Imillion gallons per day or greater permitted flow.b. Daily average- flow ý the arithmetic average of-all-determinations of-the-daily flow within a-period of-one-calendar -month. The daily average flow determination shall consist of determinations made on at least four separate days. Ifinstantaneous measurements are used to determine the daily flow, the determination shall be the arithmetic average ofall instantaneous measurements taken during that month. Daily average flow determination for intermittent dischargesshall consist of a minimum of three flow determinations on days of discharge.c. Daily maximum flow -the highest total flow for any 24-hour period in a calendar month.d. Instantaneous flow -the measured flow during the minimum time required to interpret the flow measuring device.e. 2-hour peak flow (domestic wastewater treatment plants) -the maximum flow sustained for a two-hour period duringthe period of daily discharge. The average of multiple measurements of instantaneous maximum flow within a two-hour period may be used to calculate the 2-hour peak flow.f. Maximum 2-hour peak flow (domestic wastewater treatment plants) -the highest 2-hour peak flow for any 24-hourperiod in a calender month-2. Concentration Measurementsa. Daily average concentration -the arithmetic average of all effluent samples, composite or grab as required by thispermit, within a period of one calendar month, consisting of at least four separate representative measurements.i. For domestic wastewater treatment plants -When four samples are not available in a calendar month, thearithmetic average (weighted by flow) of all values in the previous four consecutive month period consisting ofat least four measurements shall be utilized as the daily average concentration.ii. For all other wastewater treatment plants -When four samples are not available in a calender month, the arithmeticaverage (weighted by flow) of all values taken during the month shall be utilized as the daily averageconcentration.b. 7-day average concentration -the arithmetic average of all effluent samples, composite or grab as required by thispermit, within a period of one calendar week, Sunday through Saturday.c. Daily maximum concentration -the maximum concentration measured on a single day, by the sample type specifiedin the permit, within a period of one calender month.d. Daily discharge -the discharge of a pollutant measured during a calendar day or any 24-hour period that reasonablyrepresents the calendar day for purposes of sampling. For pollutants with limitations expressed in terms of mass, the"daily discharge" is calculated as the total mass of the pollutant discharged over the sampling day. For pollutants withlimitations expressed in other units of measurement, the "daily discharge" is calculated as the average measurementof the pollutant over the sampling day.The "daily discharge" determination of concentration made using a composite sample shall be the concentration of thecomposite sample. When grab samples are used, the "daily discharge" determination of concentration shall be thearithmetic average (weighted by flow'value) of all samples collected during that day.e. Fecal coliform bacteria concentration -the number of colonies of fecal coliform bacteria per 100 milliliters effluent.The daily average fecal coliform bacteria concentration is a geometric mean of the values for the effluent samplescollected in a calendar month. The geometric mean shall be determined by calculating the nth root of the product ofall measurements made in a calender month, where n equals the number of measurements made; or, computed as thePage 2 STP Nuclear Operating CompanyTPDES Permit No. WQOOO 1908000antilogarithm of the arithmetic mean of the logarithms of all measurements made in a calender month. For anymeasurement of fecal coliform bacteria equaling zero, a substituted value of one shall be made for input into eithercomputation method. The 7-day average for fecal coliform bacteria is the geometric mean of the values for all effluentsamples collected during a calender week.f. Daily average loading (lbs/day) -the arithmetic average of all daily discharge loading calculations during a period ofone calender month. These calculations must be made for each-day of the month that a parameter is analyzed. Thedaily discharge, in terms of mass (lbs/day), is calculated as ( Flow, MGD x Concentration, mg/I x 8.34).g. Daily maximum loading (lbs/day) -the highest daily discharge, in terms of mass (lbs/day), within a period of onecalender month.3. Sample Typea. Composite sample -For domestic wastewater, a composite sample is a sample made up of a minimum of three effluentportions collected in a continuous 24-hour period or during the period of daily discharge if less than 24 hours, andcombined in volumes proportional to flow, and collected at the intervals required by 30 TAC § 319.9 (a). For industrialwastewater, a composite sample is a sample made up of a minimum of three effluent portions collected in a continuous-24-hour-period-or-during-the-period of daily-discharge-if-less-than-24-hours,- and combined-in-volumesproportional toflow, and collected at the intervals required by 30 TAC § 319.9 (b).b. Grab sample -an individual sample collected in less than 15 minutes.4. Treatment Facility (facility) -wastewater facilities used in the conveyance, storage, treatment, recycling, reclamation and/ordisposal of domestic sewage, industrial wastes, agricultural wastes, recreational wastes, or other wastes including sludgehandling or disposal facilities under the jurisdiction of the Commission.5. The term "sewage sludge" is defined as solid, semi-solid, or liquid residue generated during the treatment of domesticsewage in 30 TAC Chapter 312. This includes the solids which have not been classified as hazardous waste separated fromwastewater by unit processes.6. Bypass -the intentional diversion of a waste stream from any portion of a treatment facility.MONITORING AND REPORTING REQUIREMENTS1.

This permit may be amended to require a Whole Effluent Toxicity (WET) limit, Chemical-Specific(CS) limits, a Best Management Practice (BMP), additional toxicity testing, and/or other appropriateactions to address toxicity. The permittee may be required to conduct additional biomonitoring testsand/or a Toxicity Reduction Evaluation (TRE) if biomonitoring data indicate multiple numbers ofunconfirmed toxicity events.e. Testing Frequency Reduction1) If none of the first four consecutive quarterly tests demonstrates significant lethal or sub-lethaleffects, the permittee may submit this information in writing and, upon approval from the WaterQuality Standards Team, reduce the testing frequency to once per six months for theinvertebrate test species and once per year for the vertebrate test species.2) If one or more of the first four consecutive quarterly tests demonstrates significant sub-lethaleffects, the permittee shall continue quarterly testing for that species until four consecutivequarterly tests demonstrate no significant sub-lethal effects. At that time, the permittee mayapply for the appropriate testing frequency reduction for that species.3) If one or more of the first four consecutive quarterly tests demonstrates significant lethaleffects, the permittee shall continue quarterly testing for that species until the permit is reissued.If a testing frequency reduction had been previously granted and a subsequent test demonstratessignificant lethal effects, the permittee will resume a quarterly testing frequency for that speciesuntil the permit is reissued.Page 17 STP Nuclear Operating CompanyTPDES Permit No. WQOOO 19080002. Required Toxicity Testing Conditionsa. Test Acceptance -The permittee shall repeat any toxicity test, including the control and all effluentdilutions, which fails to meet any of the following criteria:1) a control mean survival of 80% or greater;2) a control mean dry weight of surviving mysid shrimp of 0.20 mg or greater;3) a control mean dry weight for surviving unpreserved inland silverside of 0.50 mg or greater and(0.43 mg or greater for surviving preserved inland silverside.4) a control Coefficient of Variation percent (CV%) between replicates of 40 or less in the in thegrowth and survival tests.5) a critical dilution CV% of 40 or less in the growth and survival endpoints for either growth andsurvival test. However, if statistically significant lethal or nonlethal effects are exhibited at thecritical dilution,_a CV% _greater than_40 shall not'inalidatethe-test.....6) a PMSD range of 11 -37 for mysid shrimp growth;7) a PMSD range of 11 -28 for inland silverside growth.b. Statistical Interpretation1) For the mysid shrimp and the inland silverside larval survival and growth tests, the statisticalanalyses used to determine if there is a significant difference between the control and aneffluent dilution shall be in accordance with the methods described in the "Short-Term Methodsfor-Estimating the Chronic Toxicity of Effluents and Receiving Waters to Marine and EstuarineOrganisms, Third Edition" (EPA-821-R-02-014), or the most recent update thereof.2) The permittee is responsible for reviewing test concentration-response relationships to ensurethat calculated test-results are interpreted and reported correctly. The EPA manual, "MethodGuidance and Recommendation for Whole Effluent Toxicity (WET) Testing (40 CFR Part136)" (EPA 821-13-00-004) provides guidance on determining the validity of test results.3) If significant lethality is demonstrated (that is, there is a statistically significant difference insurvival at the critical dilution when compared to the control), the conditions of testacceptability are met, and the survival of the test organisms are equal to or greater than 80% inthe critical dilution and all dilutions below that, then the permittee shall report a survival NoObserved Effect Concentration (NOEC) of not less than the critical dilution for the reportingrequirements.4) The NOEC is defined as the greatest effluent dilution at which no significant effect isdemonstrated. The Lowest Observed Effect Concentration (LOEC) is defined as the lowesteffluent dilution at which a significant effect is demonstrated. A significant effect is hereindefined as a statistically significant difference at the 95% confidence level between the survival,reproduction, or growth of the test organism(s) in a specified effluent dilution compared to thesurvival, reproduction, or growth of the test organism(s) in the control (0% effluent).5) The use of NOECs and LOECs assumes either a monotonic (continuous) concentration-response relationship or a threshold model of the concentration-response relationship. For anytest result that demonstrates a non-monotonic (non-continuous) response, the NOEC should bedetermined based on the guidance manual referenced in Item 3 above and a full report will besubmitted to the Water Quality Standards Team6) Pursuant to the responsibility assigned to the permittee in Part 2.b.2), test results thatdemonstrate a non-monotonic (non-continuous) concentration-response relationship may besubmitted, prior to the due date, for technical review. The above-referenced guidance manualwill be used when making a determination of test acceptabilityPage 18 STP Nuclear Operating CompanyTPDES Permit No. WQOOO 19080007) The Water Quality Standards Team will review test results (i.e., Table I and Table 2 forms) forconsistency with established TCEQ rules, procedures, and permit requirements.c. Dilution Water1) Dilution water used in the toxicity tests shall be the receiving water collected as close aspossible to the discharge point, but unaffected by the discharge.2) Where the receiving water proves unsatisfactory as a result ofpre-existing instream toxicity (i.e.fails to fulfill the test acceptance criteria of item 2.a.), the permittee may substitute syntheticdilution water for the receiving water in all subsequent tests provided the unacceptablereceiving water test met the following stipulations:a) a synthetic lab water control was performed (in addition to the receiving water control)which fulfilled the test acceptance requirements of item 2.a;b) the test indicating receiving water toxicity was carried out to completion (i.e., 7 days);-------.c) thepermittee-submitted all-test results-indicating-receivvmg-water-toxxicity-with-thereports--and information required in Part 3.Upon approval, the permittee may substitute other appropriate dilution water with chemical andphysical characteristics similar-to that of the receiving water.d. Samples and Composites1) The permittee shall collect a minimum of three flow-weighted 24-hour composite samples fromOutfall 001. The second and.third 24-hour composite samples will be used for the renewal ofthe dilution concentrations for each toxicity test. A 24-hour composite sample consists of aminimum of 12 effluent portions collected at equal time intervals representative of a 24-houroperating day and combined proportionally to flow, or a sample continuously collectedproportionally to flow over a 24-hour operating day.2) The permittee shall collect the 24-hour composite samples such that the samples arerepresentative of any periodic episode of chlorination, biocide usage, or other potentially toxicsubstance discharged on an intermittent basis.3) The permittee shall initiate the toxicity tests within 36 hours after collection of the last portionof the first 24-hour composite sample. The holding time for any subsequent 24-hour compositesample shall not exceed 72 hours. Samples shall be maintained at a temperature of 0-6 degreesCentigrade during collection, shipping, and storage.4) If flow from the outfall being tested ceases during the collection of effluent samples, therequirements for the minimum number of effluent samples, the minimum number of effluentportions, and the sample holding time, are waived during that sampling period. However, thepermittee must have collected an effluent composite sample volume sufficient to complete therequired toxicity tests with daily renewal of the effluent. When possible, the effluent samplesused for the toxicity tests shall be collected on separate days if the discharge occurs overmultiple days. The effluent composite sample collection duration and the static renewalprotocol associated with the abbreviated sample collection must be documented in the fullreport required in Part 3 of this Section.3. ReportingAll reports, tables, plans, summaries, and related correspondence required in any Part of this Section shallbe submitted to the attention of the Water Quality Standards Team (MC 150) of the Water Quality Division.All DMRs, including DMRs with biomonitoring data, should be sent to the Water Quality ComplianceMonitoring Team of the Enforcement Division (MC 224).a.

Persistent ToxicityThe requirements of this Part apply only when a test demonstrates a significant effect at the critical dilution.A significant effect is defined as a statistically significant difference, at the 95% confidence level, betweena specified endpoint (survival, growth, or reproduction) of the test organism in a specified effluent dilutionwhen compared to the specified endpoint of the test organism in the control. Significant lethality is definedas a statistically significant difference in survival at the critical dilution when compared to the survival of thetest organism in the control. Significant sublethality is defined as a statistically significant difference ingrowth/reproduction at the critical dilution when compared to the growth/reproduction of the test organismin the control.a. The permittee shall conduct a total of 2 additional tests (retests) for any species that demonstrates asignificant effect (lethal or sublethal) at the critical dilution. The two retests shall be conductedmonthly during the next two consecutive months. The permittee shall not substitute either of the tworetests in lieu of routine toxicity testing. All reports shall be submitted within 20 days of testcompletion. Test completion is defined as the last day of the test. The retests shall also be reportedon the DMRs as specified in Part 3.d.-b.-- --fhf- t-ets-.arge--e-rf-rned~due-to-a-demonstration-of.significant-lethality and-one-orboth-ofthe-two-retests specified in item 4.a. demonstrates significant lethality, the permittee shall initiate the TRErequirements as specified in Part 5. The provisions of item 4.a. are suspended upon completion of thetwo retests and submittal of the TRE Action Plan and Schedule defined in Part 5.If neither test demonstrates significant lethality and the permittee is testing under the reduced testingfrequency provision of Part I.e., the permittee shall return to a quarterly testing frequency. for thatspecies.c. If the two retests are performed due to a demonstration of significant sublethality, and one or. both ofthe two retests specified in item 4.a. demonstrates significant lethality, the permittee shall againperform two retests as stipulated in item 4.a.d. If the- two retests are performed due to a demonstration of significant sublethality, and both retestspass, the permittee shall continue testing at the quarterly frequency until such time that the permittee.can invoke the reduced testing frequency provision specified in Part L.e.e. Regardless of whether retesting for lethal or sublethalIeffects, or a combination of the two, no morethan one retest per month is required for a species.5. Toxicity Reduction Evaluationa. Within 45 days of the last test day of the retest that demonstrates significant lethality, the permitteeshall submit a General Outline for initiating a TRE. The outline shall include, but not be limited to,a description of project personnel, a schedule for obtaining consultants (if needed), a discussion ofinfluent and/or effluent data available for review, a sampling and analytical schedule, and a proposedTRE initiation date.b. Within 90 days of the last test day of the retest that demonstrates significant lethality, the permitteeshall submit a TRE Action Plan and Schedule for conducting a TRE. The plan shall specify theapproach and methodology to be used in performing the TRE. A Toxicity Reduction Evaluation is astep-wise investigation combining toxicity testing with physical and chemical analysis to determineactions necessary to eliminate or reduce effluent toxicity to a level not effecting significant lethalityat the critical dilution. The TRE Action Plan shall lead to the successful elimination of significantlethal effects at the critical dilution for both test species defined in item I.b. As a minimum, the TREAction Plan shall include the following:I) Specific Activities -The TRE Action Plan shall specify the approach the permittee intends toutilize in conducting the TRE, including toxicity characterizations, identifications,confirmations, source evaluations, treatability studies, and/or alternative approaches. Whenconducting characterization analyses, the permittee shall perform multiple characterizations andfollow the procedures specified in the document entitled, "Toxicity Identification Evaluation:Characterization of Chronically Toxic Effluent, Phase I" (EPA/600/6-91/005F), or alternateprocedures. The permittee shall perform multiple identifications and follow the methodsPage 21 STP Nuclear Operating CompanyTPDES Permit No. WQOO0 1908000specified in the documents entitled, "Methods for Aquatic Toxicity Identification Evaluations,Phase II Toxicity Identification Procedures for Samples Exhibiting Acute and ChronicToxicity" (EPA/600/R-92/080) and "Methods for Aquatic Toxicity Identification Evaluations,Phase Ill Toxicity Confirmation Procedures for Samples Exhibiting Acute and ChronicToxicity" (EPA/600/R-92/08 1). All characterization, identification, and confirmation tests shallbe conducted in an orderly and logical progression;2) Sampling Plan -The TRE Action Plan should describe sampling locations, methods, holdingtimes, chain of custody, and preservation techniques. The effluent sample volume collected forall tests shall be adequate to perform the toxicity characterization/ identification! confirmationprocedures, and chemical-specific analyses when the toxicity tests show significant lethality.Where the permittee has identified or suspects specific pollutant(s) and/or source(s) of effluenttoxicity, the permittee shall conduct, concurrent with toxicity testing, chemical-specificanalyses for the identified and/or suspected pollutant(s) and/or source(s) of effluent toxicity;3) Quality Assurance Plan -The TRE Action Plan should address record keeping and dataevaluation, calibration and standardization, baseline tests, system blanks, controls, duplicates,--..----. spikes,-tox-icity-_persistenceein-:the:samplesrandomization; referencetoxicatt -cntrol ha-tsaswell as.mechanisms to detect artifactual toxicity; and4) Project Organization -The TRE Action Plan should describe the project staff, project manager,consulting engineering services (where applicable), consulting analytical and toxicologicalservices, etc.c. Within 30 days of submittal of the TRE Action Plan and Schedule, the permittee shall implement theTRE with due diligence.d. 'Te permittee shall submit quarterly TRE Activities Reports concerning the progress of the TRE. Thequarterly reports are due on or before April 20th, July 20th, October 20th, and January 20th. The reportshall detail information regarding the TRE activities including:1) results and interpretation of any chemical-specific analyses for the identified and/or suspectedpollutant(s) performed during the quarter;2) results and interpretation of any characterization, identification, and confirmation testsperformed during the quarter;3) any data and/or substantiating documentation which identifies the pollutant(s) and/or source(s)of effluent toxicity;4) results of any studies/evaluations concerning the treatability of the facility's effluent toxicity;5) any data which identifies effluent toxicity control mechanisms that will reduce effluent toxicityto the level necessary to meet no significant lethality at the critical dilution; and6) any changes to the initial TRE Plan and Schedule that are believed necessary as a result of theTRE findings.Copies of the TRE Activities Report shall also be submitted to the U.S. EPA Region 6 office.e. During the TRE, the permittee shall perform, at a minimum, quarterly testing using the more sensitivespecies; testing for the less sensitive species shall continiue at the frequency specified in Part 1 .b.f. If the effluent ceases to effect significant lethality (herein as defined below) the permittee may endthe TRE. A "cessation of lethality" is defined as no significant lethality for a period of 12 consecutivemonths with at least monthly testing. At the end of the 12 months, the permittee shall submit astatement of intent to cease the TRE and may then resume the testing frequency specified in Part 1 .b.The permittee may only apply the "cessation of lethality" provision once.This provision accommodate situations where operational errors and upsets, spills, or sampling errorstriggered the TRE, in contrast to a situation where a single toxicant or group of toxicants causePage 22 STP Nuclear Operating CompanyTPDES Permit No. WQOOO 1908000lethality. This provision does not apply as a result of corrective actions taken by the permittee."Corrective actions" are herein defined as proactive efforts which eliminate or reduce effluent toxicity.These include, but are not limited to, source reduction or elimination, improved housekeeping, changesin chemical usage, and modifications of influent streams and/or effluent treatment.The permittee may only apply this cessation of lethality provision once. If the effluent againdemonstrates significant lethality to the same species, the permit will be amended to add a WET limitwith a compliance period, if appropriate. However, prior to the effective date of the WET limit, thepermittee may apply for a permit amendment removing and replacing the WET limit with an alternatetoxicity control measure by identifying and confirming the toxicant and/or an appropriate controlmeasure.g. The permittee shall complete the TRE and submit a Final Report on the TRE Activities no later than28 months from the last test day of the retest that confirmed significant lethal effects at the criticaldilution. The permittee may petition the Executive Director (in writing) for an extension of the 28-month limit. However, to warrant an extension the permittee must have demonstrated due diligencein their pursuit of the TIE/TRE and must prove that circumstances beyond their control stalled theTIE/TRE. The report shall provide information pertaining to the specific control mechanism(s)on-oeduct-i.n-9f effluent-toxicity-to-no-significant-lethality-at the critical dilution. The report will also provide a specific corrective action schedule forimplementing the selected control mechanism(s). A copy of the TRE Final Report shall also besubmitted to the U.S. EPA Region 6 office.h. Based upon the results of the TRE and proposed corrective actions, this permit may be amended tomodify the biomonitoring requirements, where necessary, to require a compliance schedule forimplementation of corrective actions, to specify a WET limit, to specify a BMP, and/or to specify CSlimits.Page 23 STP Nuclear Operating CompanyTPDES Permit No. WQOOO 1908000TABLE I (SWEET 1 OF 4)MYSID SHRIMP SURVIVAL AND GROWTHDates and TimesCompositesCollectedDate TimeNo. 1 FROM:No. 2 FROM:No. 3 FROM:DateTimeTO:TO:TO:Test initiated: anm/pm __dateDilution water used:.Receiving water___ Synthetic Dilution waterMYSID SHRIMP SURVIVAL-Pei&&n PctSiram Mexecent:I ': -...* coefficient of variation = standard deviation x 100/meanDATA TABLE FOR GROWTH OF MYSID SHRIMPAte-- -:w ":. i -b"s'Re'nl.. icateB. ..

During the TRE, the permittee shall perform, at a minimum, quarterly testing using the more sensitivespecies; testing for the less sensitive species shall continue at the frequency specified in Part I .b.f. If the effluent ceases to effect significant lethality (herein as defined below) the permittee may endthe TRE. A "cessation of lethality" is defined as no significant lethality for a period of 12 consecutiveweeks with at least weekly testing. At the end of the 12 weeks, the permittee shall submit a statementof intent to cease the TRE and may then resume the testing frequency specified in Part I.b. Thepermittee may only apply the "cessation of lethality" provision once.This provision accommodate situations where operational errors and upsets, spills, or sampling errorstriggered the TRE, in contrast to a situation where a single toxicant or group of toxicants causelethality. This provision does not apply as a result of corrective actions taken by the permittee."Corrective actions" are herein defined as proactive efforts which eliminate or reduce effluent toxicity.These include, but are not limited to, source reduction or elimination, improved housekeeping, changesin chemical usage, and modifications of influent streams and/or effluent treatment.The permittee may only apply this cessation of lethality provision once. If the effluent againdemonstrates significant lethality to the same species, the permit will be amended to add a WET limitwith a compliance period, if appropriate. However, prior to the effective date of the WET limit, thePage 31 I-STP Nuclear Operating Company TPDES Permit No. WQ0001908000pennittee may apply for a permit amendment removing and replacing the WET limit with an alternatetoxicity control measure by identifying and confirming the toxicant and/or an appropriate controlmeasure.g. The pennittee shall complete the TRE and submit a Final Report on the TRE Activities no later than18 months from the last test day of the retest that demonstrates significant lethality.

Scope, Frequency and Methodologya. The permittee shall test the effluent for toxicity in accordance with the provisions below. Such testingwill determine if an appropriately dilute effluent sample adversely affects the survival, reproduction,or growth of the test organisms.b. The permittee shall conduct all toxicity tests utilizing the test organisms, procedures, and qualityassurance requirements specified below and in accordance with "Short-Term Methods for Estimatingthe Chronic Toxicity of Effluents and Receiving Waters to Marine and Estuarine Organisms, ThirdEdition" (EPA-821 -R-02-014), or the most recent update thereof:1) Chronic static renewal 7-day survival and growth test using the mysid shrimp (Mysidopsisbahia) (Method 1007.0 or the most recent update thereof). A minimum of eight replicates withfive organisms per replicate shall be used in the control and in each dilution. This test shall becondiimtd onc-per quarter.2) Chronic static renewal 7-day larval survival and growth test using the inland silverside(Menidia beryllina) (Method 1006.0 or the most recent update thereof). A minimum of fivereplicates with eight organisms per replicate shall be used in the control and in each dilution.This test shall be conducted once per quarter.The permittee must perform and report a valid test for each test species during the prescribed reportingperiod. An invalid test must be repeated during the same reporting period. An invalid test ishereindefined as any test failing to satisfy the test acceptability criteria, including Percent MinimumSignificant Difference (PMSD) boundary requirements, procedures, and quality assurancerequirements specified in the test methods and permit. All test results, valid or invalid, must besubmitted as described below.c. The permittee shall use five effluent dilution concentrations and a control in each toxicity test. Theseadditional effluent concentrations are 5%, 7%, 10%, 13%, and 17% effluent. The critical dilution,defined as 13% effluent, is the effluent concentration representative of the proportion of effluent inthe receiving water during critical low flow or critical mixing conditions.d. This permit may be amended to require a Whole Effluent Toxicity (WET) limit, Chemical-Specific(CS) limits, a Best Management Practice (BMP), additional toxicity testing, and/or other appropriateactions to address toxicity. The permittee may be required to conduct additional biomonitoring testsand/or a Toxicity Reduction Evaluation (TRE) if biomonitoring data indicate multiple numbers ofunconfirmed toxicity events.e. Testing Frequency Reduction1) If none of the first four consecutive quarterly tests demonstrates significant lethal or sub-lethaleffects, the permittee may submit this information in writing and, upon approval from the WaterQuality Standards Team, reduce the testing frequency to once per six months for theinvertebrate test species and once per year for the vertebrate test species.2) If one or more of the first four consecutive quarterly tests demonstrates significant sub-lethaleffects, the permittee shall continue quarterly testing for that species until four consecutivequarterly tests demonstrate no significant sub-lethal effects. At that time, the permittee mayapply for the appropriate testing frequency reduction for that species.3) If one or more of the first four consecutive quarterly tests demonstrates significant lethaleffects, the permittee shall continue quarterly testing for that species until the permit is reissued.If a testing frequency reduction had been previously granted and a subsequent test demonstratessignificant lethal effects, the permittee will resume a quarterly testing frequency for that speciesuntil the permit is reissued.Page 17 STP Nuclear Operating CompanyTPDES Permit No. WQOOO 19080002. Required Toxicity Testing Conditionsa. Test Acceptance -The permittee shall repeat any toxicity test, including the control and all effluentdilutions, which fails to meet any of the following criteria:1) a control mean survival of 80% or greater;2) a control mean dry weight of surviving mysid shrimp of 0.20 mg or greater;3) a control mean dry weight for surviving unpreserved inland silverside of 0.50 mg or greater and(0.43 mg or greater for surviving preserved inland silverside.4) a control Coefficient of Variation percent (CV%) between replicates of 40 or less in the in thegrowth and survival tests.5) a critical dilution CV% of 40 or less in the growth and survival endpoints for either growth andsurvival test. However, if statistically significant lethal or nonlethal effects are exhibited at thecritical dilution,_a CV% _greater than_40 shall not'inalidatethe-test.....6) a PMSD range of 11 -37 for mysid shrimp growth;7) a PMSD range of 11 -28 for inland silverside growth.b. Statistical Interpretation1) For the mysid shrimp and the inland silverside larval survival and growth tests, the statisticalanalyses used to determine if there is a significant difference between the control and aneffluent dilution shall be in accordance with the methods described in the "Short-Term Methodsfor-Estimating the Chronic Toxicity of Effluents and Receiving Waters to Marine and EstuarineOrganisms, Third Edition" (EPA-821-R-02-014), or the most recent update thereof.2) The permittee is responsible for reviewing test concentration-response relationships to ensurethat calculated test-results are interpreted and reported correctly. The EPA manual, "MethodGuidance and Recommendation for Whole Effluent Toxicity (WET) Testing (40 CFR Part136)" (EPA 821-13-00-004) provides guidance on determining the validity of test results.3) If significant lethality is demonstrated (that is, there is a statistically significant difference insurvival at the critical dilution when compared to the control), the conditions of testacceptability are met, and the survival of the test organisms are equal to or greater than 80% inthe critical dilution and all dilutions below that, then the permittee shall report a survival NoObserved Effect Concentration (NOEC) of not less than the critical dilution for the reportingrequirements.4) The NOEC is defined as the greatest effluent dilution at which no significant effect isdemonstrated. The Lowest Observed Effect Concentration (LOEC) is defined as the lowesteffluent dilution at which a significant effect is demonstrated. A significant effect is hereindefined as a statistically significant difference at the 95% confidence level between the survival,reproduction, or growth of the test organism(s) in a specified effluent dilution compared to thesurvival, reproduction, or growth of the test organism(s) in the control (0% effluent).5) The use of NOECs and LOECs assumes either a monotonic (continuous) concentration-response relationship or a threshold model of the concentration-response relationship. For anytest result that demonstrates a non-monotonic (non-continuous) response, the NOEC should bedetermined based on the guidance manual referenced in Item 3 above and a full report will besubmitted to the Water Quality Standards Team6) Pursuant to the responsibility assigned to the permittee in Part 2.b.2), test results thatdemonstrate a non-monotonic (non-continuous) concentration-response relationship may besubmitted, prior to the due date, for technical review. The above-referenced guidance manualwill be used when making a determination of test acceptabilityPage 18 STP Nuclear Operating CompanyTPDES Permit No. WQOOO 19080007) The Water Quality Standards Team will review test results (i.e., Table I and Table 2 forms) forconsistency with established TCEQ rules, procedures, and permit requirements.c. Dilution Water1) Dilution water used in the toxicity tests shall be the receiving water collected as close aspossible to the discharge point, but unaffected by the discharge.2) Where the receiving water proves unsatisfactory as a result ofpre-existing instream toxicity (i.e.fails to fulfill the test acceptance criteria of item 2.a.), the permittee may substitute syntheticdilution water for the receiving water in all subsequent tests provided the unacceptablereceiving water test met the following stipulations:a) a synthetic lab water control was performed (in addition to the receiving water control)which fulfilled the test acceptance requirements of item 2.a;b) the test indicating receiving water toxicity was carried out to completion (i.e., 7 days);-------.c) thepermittee-submitted all-test results-indicating-receivvmg-water-toxxicity-with-thereports--and information required in Part 3.Upon approval, the permittee may substitute other appropriate dilution water with chemical andphysical characteristics similar-to that of the receiving water.d. Samples and Composites1) The permittee shall collect a minimum of three flow-weighted 24-hour composite samples fromOutfall 001. The second and.third 24-hour composite samples will be used for the renewal ofthe dilution concentrations for each toxicity test. A 24-hour composite sample consists of aminimum of 12 effluent portions collected at equal time intervals representative of a 24-houroperating day and combined proportionally to flow, or a sample continuously collectedproportionally to flow over a 24-hour operating day.2) The permittee shall collect the 24-hour composite samples such that the samples arerepresentative of any periodic episode of chlorination, biocide usage, or other potentially toxicsubstance discharged on an intermittent basis.3) The permittee shall initiate the toxicity tests within 36 hours after collection of the last portionof the first 24-hour composite sample. The holding time for any subsequent 24-hour compositesample shall not exceed 72 hours. Samples shall be maintained at a temperature of 0-6 degreesCentigrade during collection, shipping, and storage.4) If flow from the outfall being tested ceases during the collection of effluent samples, therequirements for the minimum number of effluent samples, the minimum number of effluentportions, and the sample holding time, are waived during that sampling period. However, thepermittee must have collected an effluent composite sample volume sufficient to complete therequired toxicity tests with daily renewal of the effluent. When possible, the effluent samplesused for the toxicity tests shall be collected on separate days if the discharge occurs overmultiple days. The effluent composite sample collection duration and the static renewalprotocol associated with the abbreviated sample collection must be documented in the fullreport required in Part 3 of this Section.3. ReportingAll reports, tables, plans, summaries, and related correspondence required in any Part of this Section shallbe submitted to the attention of the Water Quality Standards Team (MC 150) of the Water Quality Division.All DMRs, including DMRs with biomonitoring data, should be sent to the Water Quality ComplianceMonitoring Team of the Enforcement Division (MC 224).a.

Persistent ToxicityThe requirements of this Part apply only when a test demonstrates a significant effect at the critical dilution.A significant effect is defined as a statistically significant difference, at the 95% confidence level, betweena specified endpoint (survival, growth, or reproduction) of the test organism in a specified effluent dilutionwhen compared to the specified endpoint of the test organism in the control. Significant lethality is definedas a statistically significant difference in survival at the critical dilution when compared to the survival of thetest organism in the control. Significant sublethality is defined as a statistically significant difference ingrowth/reproduction at the critical dilution when compared to the growth/reproduction of the test organismin the control.a. The permittee shall conduct a total of 2 additional tests (retests) for any species that demonstrates asignificant effect (lethal or sublethal) at the critical dilution. The two retests shall be conductedmonthly during the next two consecutive months. The permittee shall not substitute either of the tworetests in lieu of routine toxicity testing. All reports shall be submitted within 20 days of testcompletion. Test completion is defined as the last day of the test.

The provisions of item 4.a. are suspended upon completion of thetwo retests and submittal of the TRE Action Plan and Schedule defined in Part 5.If neither test demonstrates significant lethality and the permittee is testing under the reduced testingfrequency provision of Part I.e., the permittee shall return to a quarterly testing frequency. for thatspecies.c. If the two retests are performed due to a demonstration of significant sublethality, and one or. both ofthe two retests specified in item 4.a. demonstrates significant lethality, the permittee shall againperform two retests as stipulated in item 4.a.d. If the- two retests are performed due to a demonstration of significant sublethality, and both retestspass, the permittee shall continue testing at the quarterly frequency until such time that the permittee.can invoke the reduced testing frequency provision specified in Part L.e.e. Regardless of whether retesting for lethal or sublethalIeffects, or a combination of the two, no morethan one retest per month is required for a species.5. Toxicity Reduction Evaluationa.

If the effluent ceases to effect significant lethality (herein as defined below) the permittee may endthe TRE. A "cessation of lethality" is defined as no significant lethality for a period of 12 consecutivemonths with at least monthly testing. At the end of the 12 months, the permittee shall submit astatement of intent to cease the TRE and may then resume the testing frequency specified in Part 1 .b.The permittee may only apply the "cessation of lethality" provision once.This provision accommodate situations where operational errors and upsets, spills, or sampling errorstriggered the TRE, in contrast to a situation where a single toxicant or group of toxicants causePage 22 STP Nuclear Operating CompanyTPDES Permit No. WQOOO 1908000lethality.

No samples or portions of samples from one outfall may be composited with samples or portionsof samples from another outfall.I Scope, Frequency and Methodologya. The permittee shall test the effluent for lethality in accordance with the provisions in this Section.Such testing will determine compliance with the Surface Water Quality Standard, 30 TAC§307.6(e)(2)(B), of greater than 50% survival of the appropriate test organisms in 100% effluent fora 24-hour period.b. The toxicity tests specified shall be conducted once per six months. The permittee shall conduct thefollowing toxicity tests utilizing the test organisms, procedures, and quality assurance requirementsspecified in this section of the permit and in accordan e-with"Methods-for-Measuring--the-Acute-..... Effl-rits and Receiving to Freshwater and Marine Organisms, Fifth Edition"(EPA-82 1 -R-02-012), or the most recent update thereof:1) Acute 24-hour static toxicity test using the mysid shrimp (Mysidopsis bahia). A minimum offive replicates with eight organisms per replicate shall be used in the control and in eachdilution.2) Acute 24-hour static toxicity test using the inland silverside (Menidia beryllina). A minimumof five replicates with eight organisms per replicate shall be used in the control and in eachdilution.The permittee must perform and report a valid test for each test species during the prescribed reportingperiod. An invalid test must be repeated during the same reporting period. An invalid test is hereindefined as any test failing to satisfy the test acceptability criteria, procedures, and quality assurancerequirements specified in the test methods and permit. All test results, valid or invalid, must besubmitted as described below.c. In addition to an appropriate control, a 100% effluent concentration shall be used in the toxicity tests.Except as discussed in item 2.b., the control and/or dilution water shall consist of a standard, synthetic,moderately hard, reconstituted water.d. This permit may be amended to require a Whole Effluent Toxicity (WET) limit, a Best ManagementPractice (BMP), a Chemical-Specific (CS) limit, additional toxicity testing, and/or other appropriateactions to address toxicity. The permittee may be required to conduct additional biomonitoring testsand/or a Toxicity Reduction Evaluation (TRE) if biomonitoring data indicate multiple numbers ofunconfirmed toxicity events.e. If the biomonitoring dilution series specified in the Chronic biomonitoring requirements includes a100% effluent concentration, those results may fulfill the requirements of this Section. The results ofany test with a 100% effluent concentration performed in the proper time interval may be substitutedin lieu of performing a separate 24-hour acute test. Compliance will be evaluated as specified in itema. The greater than 50% survival in 100% effluent for a 24-hour period standard applies to all testsutilizing a 100% effluent dilution, regardless of whether the results are submitted to comply with theminimum testing frequency defined in item b.2.

The permittee shall submit quarterly TRE Activities Reports concerning the progress of the TRE. Thequarterly TRE Activities Reports are due on or before April 20th, July 20th, October 20th, and January20th. The report shall detail information regarding the TRE activities including:1) results and interpretation of any chemical-specific analyses for the identified and/or suspectedpollutant(s) performed during the quarter;2) results and interpretation of any characterization, identification, and confirmation testsperformed during the quarter;3) any data and/or substantiating documentation which identifies the pollutant(s) and/or source(s)of effluent toxicity;4) results of any studies/evaluations concerning the treatability of the facility's effluent toxicity;5) any data which identifies effluent toxicity control mechanisms that will reduce effluent toxicityto the level necessary to eliminate significant lethality; and6) any changes to the initial TRE Plan and Schedule that are believed necessary as a result of theTRE findings.Copies of the TRE Activities Report shall also be submitted to the U.S. EPA Region 6 office.e. During the TRE, the permittee shall perform, at a minimum, quarterly testing using the more sensitivespecies; testing for the less sensitive species shall continue at the frequency specified in Part I .b.f. If the effluent ceases to effect significant lethality (herein as defined below) the permittee may endthe TRE. A "cessation of lethality" is defined as no significant lethality for a period of 12 consecutiveweeks with at least weekly testing. At the end of the 12 weeks, the permittee shall submit a statementof intent to cease the TRE and may then resume the testing frequency specified in Part I.b. Thepermittee may only apply the "cessation of lethality" provision once.This provision accommodate situations where operational errors and upsets, spills, or sampling errorstriggered the TRE, in contrast to a situation where a single toxicant or group of toxicants causelethality. This provision does not apply as a result of corrective actions taken by the permittee."Corrective actions" are herein defined as proactive efforts which eliminate or reduce effluent toxicity.These include, but are not limited to, source reduction or elimination, improved housekeeping, changesin chemical usage, and modifications of influent streams and/or effluent treatment.The permittee may only apply this cessation of lethality provision once. If the effluent againdemonstrates significant lethality to the same species, the permit will be amended to add a WET limitwith a compliance period, if appropriate. However, prior to the effective date of the WET limit, thePage 31 I-STP Nuclear Operating Company TPDES Permit No. WQ0001908000pennittee may apply for a permit amendment removing and replacing the WET limit with an alternatetoxicity control measure by identifying and confirming the toxicant and/or an appropriate controlmeasure.g. The pennittee shall complete the TRE and submit a Final Report on the TRE Activities no later than18 months from the last test day of the retest that demonstrates significant lethality. The permitteemay petition the Executive Director (in writing) for an extension of the 18-month limit. However, towarrant an extension the permittee must have demonstrated due diligence in their pursuit of theTIE/FRE and must prove that circumstances beyond their control stalled the TIE/TRE. The reportshall specify the control mechanism(s) that will, when implemented, reduce effluent toxicity asspecified in item 5.g. The report will also specify a corrective action schedule for implementing theselected control mechanism(s). A copy of the TRE Final Report shall also be submitted to the U.S.EPA Region 6 office.h.

==Dear Mr. Holligan:== | |||
Thank you for meeting with my staff on May 15, 2007 to discuss the South Texas ProjectElectric Generating Station (STPEGS) cooling reservoir and other wastewater discharge permitissues. Based on our discussion, STP Nuclear Operating Company (STPNOC) is submitting thefollowing information regarding the Main Cooling Reservoir (MCR) and the applicability of theregulations for cooling water intake structures. We are confident that the South Texas ProjectStation (STP) complies with the regulation by employing a closed-cycle recirculating coolingsystem as defined in 40 CFR § 125.93. Pursuant to 40 CFR §125.94(a)(1)(i), cooling water flowfor this facility is commensurate with a closed-cycle recirculating cooling system, asdemonstrated below. Additional technical information is included in letters dated March 7, 2005and August 18, 2005 previously submitted to the Texas Commission on Environmental Quality(TCEQ).STP is located on 12,220-acres in Matagorda County, approximately 15 miles southwest of BayCity along the west bank of the Colorado River. The facility consists of two electric-generatingunits, which share a closed-cycle recirculating cooling reservoir. Water from the MCR is passedthrough the cooling loops of both units then returned to the MCR for heat dissipation beforecycling back through the cooling systems.The MCR is a perched, off-channel, on-site industrial cooling impoundment of approximately7,000 acres, impounding over 202,600 acre-feet of cooling water at its maximum operating level.Dikes are installed in the MCR that channel the water flow to maximize circulation time for heatdissipation before the water is recirculated back to the generating units. Blowdown from theMCR to the Colorado River has not occurred since March 1997. Should blowdown be requiredit would occur through an underground pipe that discharges back into the Colorado River. Thispoint is designated as Outfall 001 in the TPDES Permit No. 01908. The MCR is also equippedwith a gated spillway for emergency use. The MCR is not a "water of the U.S." as defined at 40CFR § 122.2. The MCR is not considered a "water of the State" based on internal and externaloutfall designations in the permit. The MCR is on private property and exists solely for Mr. Kelly HolliganMay 24, 2007Page 2industrial cooling. It is not a publicly managed water body and has no recreational uses. Thegeneral public has never had access to the NMICR nor is any planned in the foreseeable future.The only sources of new water to the MCR are direct rainfall and make-up water divertedperiodically from the Colorado River, primarily at high river flows. Water from the ColoradoRiver is pumped approximately I mile via a 108 inch pipe to the MCR. To protect inflows duringlow river flow conditions, the water right for STP includes a special provision to limit diversionfrom the Colorado River to 55% of the flow over 300 cubic feet per second, to protect inflowsduring low river flow conditions. Currently, the intake consists of irash racks, rotating screenswith 3/8 inch mesh and 4 pumps. In addition, the reservoir makeup pumping facility has thefollowing design:" The traveling water screens are flush with the river shoreline;* The maximum approach velocity to the traveling water screens is 0.5 feet per second;" Fish passageways were constructed in the wing walls between the traveling screens tofacilitate fish migration parallel to the screen surfaces; and* A sluice and discharge line was installed for the purpose of returning all impingedorganisms directly to the river, downstream of the intake structure, immediately afterbeing backwashed from the screens.The pumps are operated intermittently based on reservoir level, river flow, and the operability ofthe makeup pumping facility. A cooling reservoir evaporates less water per unit of heatdissipated than a cooling tower, thus dissolved solids build up more slowly over time. This iscomplemented by the designed seepage from the MCR, which maintains the structural integrityof the reservoir embankment. Rainfall further dilutes the dissolved solids in the MCR. Thesefactors minimize the blowdown and make-up required to maintain MCR water quality. As aresult, intake water flow for cooling purposes at STP reflects best technology available (closed-cycle recirculating systems) for minimizing adverse environmental impact.As was discussed in the May 15, 2007 meeting, several provisions of the Phase 11 rule are in theprocess of being suspended by the U.S. Environmental Protection Agency and the RegionalAdministrators have been authorized to review the applicability of the rule on a case by casebasis using Best Professional Judgment. Based on that authorization and the informationprovided, STPNOC is requesting that TCEQ designate the MCR as a closed-cycle recirculatingsystem. We are also requesting concurrence that the MCR does not meet the definition of a"water of the State". If you have any questions or require additional information, please contactMs. S. L. Dannhardt at (361) 972-8328.Sincerely,R. A.

Describe existing disturbances, vegetation & land useThe area surrounding the South Texas Project is characterized by coastal plain with farmland and pasturepredominating. Sixty-five of the 12,220 acres are occupied by the two current power plants. Plant facilities Includea 7,000-acre cooling reservoir and a 47-acre essential cooling pond. Many smaller bodies of water onsite Includewetlands, Kelly Lake, and natural and engineered drainage ditches. Much of the land east of the reservoir is leasedfor cattle grazing.

Describe the wastewater generating processes.Main Cooling Reservoir- Outfall 001Outfall 001 is Me discharge point for the 7,100-acre main cooling reservoir. This resetvo r Is part of the main recirculating cooling water loop used toremove heat from the steam-electric generating units. There has not been a discharge from Outfall 001 since March 1997 other than minor permittedleakage tihough the closed spillway gates and relief wells. If a discharge were to occur, blowdown from the main cooling reservoir would make up thelargest percentage of wastewater. A discharge from Outfall 001 would flow to the Colorado River (Colorado River Tidal in Segment 1401 of theColorado River Basin).All internal outfalls (Outfall 101, 201, 401, and 601) discharge to the main cooling reservoir. Outfall 501 would also discharge to the reservoir viaOutfall 101. but has not discharged since 1992.Low Volume Wastewater (Outfalla 101 and 201)Low volume wasutwator results from water treatment operations, boiler blowdown. HVAC bbowdown, floor drains and SPCC sources and theirassociated oily watet treatment system discharges, and other miscellaneous Sources. Boiler blowdown Is from one auxiliary steam boiler, released toreduce impurities In the water that can cause corrosion and boiler tube fallure. Service water Is denineralzed and regeneration of the demineralzerresin beds produces an acidic and caustic wastewater that is treated at the neutralization basins along with boiler blowdown. The floor drain systemcaptures condensate and water from production and maintenance areas that may contain oil or grease, which Is then transported to the oily wastetr"atment system where the oil is separated from the water. The first flush of storm water from production and storage area is also treated Inthe oily waste system. Other non-process storm water flow is directed through designated storm water outrfaIl.Treated Domestic Wastewater (Out lsts 401 and 601)Domestic wastewater Is treated onsite in two package treatment systems consisting of aeration, clarificaion, and disinfection. Car wash water, airconditioning condensate, HVAC cooling tower blowdown, and storm water are commingled with the domestic wastewater puior to treatment.Metal Cleaning Waste (Outfalla 501)Metal cleaning waste has not been discharged since 1992- Cleaning of metal using chemical or non-chemical liquids produces a waste that would bedischarged through Outfall 501 to the neutralization basins (Outfall 1t1).

The floor drain systemcaptures condensate and water from production and maintenance areas that may contain oil or grease, which Is then transported to the oily wastetr"atment system where the oil is separated from the water. The first flush of storm water from production and storage area is also treated Inthe oily waste system. Other non-process storm water flow is directed through designated storm water outrfaIl.Treated Domestic Wastewater (Out lsts 401 and 601)Domestic wastewater Is treated onsite in two package treatment systems consisting of aeration, clarificaion, and disinfection. Car wash water, airconditioning condensate, HVAC cooling tower blowdown, and storm water are commingled with the domestic wastewater puior to treatment.Metal Cleaning Waste (Outfalla 501)Metal cleaning waste has not been discharged since 1992- Cleaning of metal using chemical or non-chemical liquids produces a waste that would bedischarged through Outfall 501 to the neutralization basins (Outfall 1t1). Storm water may also be discharged through Outfall 501.d.

==Dear Mr. Holligan:== | |||
Thank you for meeting with my staff on May 15, 2007 to discuss the South Texas ProjectElectric Generating Station (STPEGS) cooling reservoir and other wastewater discharge permitissues. Based on our discussion, STP Nuclear Operating Company (STPNOC) is submitting thefollowing information regarding the Main Cooling Reservoir (MCR) and the applicability of theregulations for cooling water intake structures. We are confident that the South Texas ProjectStation (STP) complies with the regulation by employing a closed-cycle recirculating coolingsystem as defined in 40 CFR §125.93. Pursuant to 40 CFR §125.94(a)(1)(i), cooling water flowfor this facility is commensurate with a closed-cycle recirculating cooling system, asdemonstrated below. Additional technical information is included in letters dated March 7, 2005and August 18, 2005 previously submitted to the Texas Commission on Environmental Quality(TCEQ).STP is located on 12,220-acres in Matagorda County, approximately 15 miles southwest of BayCity along the west bank of the Colorado River. The facility consists of two electric-generatingunits, which share a closed-cycle recirculating cooling reservoir. Water from the MCR is passedthrough the cooling loops of both units then returned to the MCR for heat dissipation beforecycling back through the cooling systems.The MCR is a perched, off-channel, on-site industrial cooling impoundment of approximately7,000 acres, impounding over 202,600 acre-feet of cooling water at'its maximum operating level.Dikes are installed in the MCR that channel the water flow to maximize circulation time for heatdissipation before the water is recirculated back to the generating units. Blowdown from theMCR to the Colorado River has not occurred since March 1997. Should blowdown be requiredit would occur through an underground pipe that discharges back into the Colorado River. Thispoint is designated as Outfall 001 in the TPDES Permit No. 01908. The MCR is also equippedwith a gated spillway for emergency use. The MCR is not a "water of the U.S." as defined at 40CFR § 122.2. The MCR is not considered a "water of the State" based on internal and externaloutfall designations in the permit. The MCR is on private property and exists solely for Mr. Kelly HolliganMay 24, 2007Page 2industrial cooling. It is not a publicly managed water body and has no recreational uses. Thegeneral public has never had access to the MCR nor is any planned in the foreseeable future.The only sources of new water to the MCR are direct rainfall and make-up water divertedperiodically from the Colorado River, primarily at high river flows. Water from the ColoradoRiver is pumped approximately I mile via a 1 0 inch pipe to the MCR. To protect inflows duringlow river flow conditions, the water right for STP includes a special provision to limit diversionfrom the Colorado River to 55% of the flow over 300 cubic feet per second, to protect inflowsduring low river flow conditions. Currently, the intake consists of trash racks, rotating screenswith 3/8 inch mesh and 4 pumps. In addition, the reservoir makeup pumping facility has thefollowing design:" The traveling water screens are flush with the river shoreline;* The maximum approach velocity to the traveling water screens is 0.5 feet per second;* Fish passageways were constructed in the wing walls between the traveling screens tofacilitate fish migration parallel to the screen surfaces; and" A sluice and discharge line was installed for the purpose of returning all impingedorganisms directly to the river, downstream of the intake structure, immediately afterbeing backwashed from the screens.The pumps are operated intermittently based on reservoir level, river flow, and the operability ofthe makeup pumping facility. A cooling reservoir evaporates less water per unit of heatdissipated than a cooling tower, thus dissolved solids build up more slowly over time. This iscomplemented by the designed seepage from the MCR, which maintains the structural integrityof the reservoir embankment. Rainfall further dilutes the dissolved solids in the MCR. Thesefactors minimize the blowdown and make-up required to maintain MCR water quality. As aresult, intake water flow for cooling purposes at STP reflects best technology available (closed-cycle recirculating systems) for minimizing adverse environmental impact.As was discussed in the May 15, 2007 meeting, several provisions of the Phase II rule are in theprocess of being suspended by the U.S. Environmental Protection Agency and the RegionalAdministrators have been authorized to review the applicability of the rule on a case by casebasis using Best Professional Judgment. Based on that authorization and the informationprovided, STPNOC is requesting that TCEQ designate the MCR as a closed-cycle recirculatingsystem. We are also requesting concurrence that the MCR does not meet the definition of a"water of the State". If you have any questions or require additional information, please contactMs. S. L. Dannhardt at (361) 972-8328.Sincerely,R A.

==Dear Mr. Gangluff:== | |||
I received your letter dated May 24, 2007, requesting that the Main Cooling Reservoir (MCR) bedesignated as a closed-cycle recirculating system and as not water in the state.The Texas Commission on Environmental Quality (TCEQ) does not have an official method of"designating" a facility's operation as a closed-cycle recirculating system. However, we have reviewedthe information you submitted and based on our best professional judgement, we consider your facility tobe a closed-cycle recirculating system. As mentioned in your letter, the federal rule governing the 316(b)Phase II cooling water intakes is currently in the process of being suspended. For the time being,implementation of the 316(b) requirements will be based on best professional judgement (BPJ) andsubject to EPA Region VI review.We also concur that the Main Cooling Reservoir (MCR) at your facility does not meet the definition ofwater in the state.If you have any questions, please contact me at (512) 239-2369.Sincerely,Kelly Holligan, LeaderIndustrial TeamWater Quality DivisionKH/jpP.O.

Submission of driller's log records upon completion of adrilled water well became mandatory in 1985. The state of Texas has processed these records into several different filingsystems within two state regulatory authorities. The water well files, records and map locations are maintained by the TexasCommission on Environmental Quality (TCEQ) and the Texas Water Development Board (TWDB). Actual water well sitelocations of this report are geocoded and geoplotted directly from the drilling records, drilling schedules, and driller's logs andmaps submitted by the water well driller and maintained at these two primary water well regulatory authorities. Below is adescription of the filing systems utilized for well drilling records.Texas Water Development Board (TWDB)The Texas Water Development Board maintains two datasets of located water well records:TWDB Groundwater Data-These well files are water well site locations that have been verified with a field inventoryinspection by TWDB personnel. The wells are assigned a State Identification Number unique to that well (ex. 65-03-401) andplotted on county base maps, U.S.G.S. 7.5 minute topographical quadrangle maps, as well as in-house and on linegeographic information systems. Records may also include analytical data attached with each drilling record.TWDB Submitted Drillers Reports- A Database created from the online Texas Well Report Submission and Retrieval System(A cooperative TDLR. TWDB system) that registered water-well drillers use to submit their required reports. Reports thatdrillers submit by mail are geoplotted/geocoded by a TWDB staff member. These wells are assigned a unique trackingnumber by the Texas Well Report Submission and Retrieval System. This system was introduced in February 2001 as anoption for drillers to use, and will be mandatory in the future.Texas Commission on Environmental QualityThe Texas Commission on Environmental Quality (TCEQ) maintains two datasets of water well records.Water Utility Database*(WUD) -This database contains a collection of data from Texas Water Districts, Public Drinking WaterSystems and Water and Sewer Utilities who submit information to the TCEQ. These wells are assigned unique numbers withcorrelate to the Public Water System they act as a source for (example- $2200199A, G2200322A). The WUD does notcontain Drillers Reports or analytical data. This data was provided to Banks in digital format.TCEQ Central Records-Several different types of Driller's Reports are filed with TCEQ Central Records according to theState Grid Number.Plotted water well files are water well site locations that have been determined from map information submitted on water welllogs and subsequently plotted on TWDB county highway base maps. The accuracy and location of these wells is relative tothe information provided on the drillers report. TWDB assigned letters to the correlating grid number to identify these wells(example -65-59-1A). In some instances, a single well number can represent more than one well location. This type ofmapping and filing procedure ceased in June 1986.Partially numbered water wells -Well Reports that were provided a State Identification Number by the TWDB whichestablishes the well location somewhere within a 2.5 minute quadrant of a 7.5 minute quadrangle map. This method was thestandard procedure from 1986 through 1991. From 1991 to the 2001, Texas Well Reports contain a grid location box, wheredrillers are provided a place to mark an X where within the 2.5 minute quadrant is located. These locations have not beenverified by the state.Unnumbered water well files are water well site locations that have been processed since June 1990. These well records arefiled solely on their county location and are not provided a State Identifiation Number nor are they mapped.DisclaimerBanks Environmental Data has performed a thorough and diligent search of all wells recorded with the Texas WaterDevelopment Board and the Texas Commission on Environmental Quality. All mapped locations are based on informationobtained from the TWDB and the TCEQ. Although Banks performs quality assurance and quality control on all researchprojects, we recognize that any inaccuracies of the records and mapped well locations could possibly be traced to theappropriate regulatory authority or the water well driller. Many water well schedules may have never been submitted to theregulatory authority by the water well driller and, thus. may explain the possible unaccountability of private drilled wells. It isuncertain if the above listing provides 100% of the existing well locations within the area of review.

SUBJECT:
SWG-2007-786; South Texas Project Nuclear Operating Company, Units 3 & 4,Preliminary Jurisdictional Determination, Wadsworth, Montgomery County, TexasMr. Russell KieslingSouth Texas Project Nuclear Operating CompanyP.O. Box 289Wadsworth, Texas 77483
Dear Mr. Kiesling:
This letter is in response to your April 11, 2008 request for a jurisdictional determination onthe proposed project site for the construction of Units 3 & 4. The 1406.5-acre project site islocated on Farm-to-Market 521, approximately 8 miles west of Wadsworth, Matagorda County,Texas.Based on the review of the information associated with this request, we determined that therevised delineation map dated May 13, 2009 (enclosed) is a reasonable depiction of theapproximate locations of the aquatic resources with the tract. Computation ofjurisdiction madeon the basis of this preliminary jurisdictional determination will treat all waters, includingwetlands, on the 1406.5-acre tract as jurisdictional water of the United States. As such allaquatic resources, including 17.6 acres of wetlands and 24,639 linear feet of non-wetland watersare subject to Section 404 of the Clean Water Act and will require a Department of the Armypermit prior to the discharge of any dredged and/or fill material into these aquatic resources.Wetlands were identified on the tract using the 1987 Corps of Engineers Wetland DelineationManual which requires that under normal conditions wetlands exhibit wetland hydrology, hydricsoils, and hydrophytic vegetation.This determination has been conducted to identify the limits of the Corps' Clean Water Actjurisdiction for the particular site identified in this request. This determination may not be validfor the wetland conservation provisions of the Food Security Act of 1985, as amended. If you oryour tenant are USDA program participants, or anticipate participation in USDA programs, youshould request a certified wetland determination from the local office of the Natural ResourcesConservation Service prior to starting work. This preliminary jurisdictional determination is valid for 5 years from the date of this letter,unless new information warrants a revision prior to the expiration date. An approvedjurisdictional determination can be requested at any time. If you have any questions concerningthis matter, please reference file number SWG-2007-786 and contact Mr. Nicholas Laskowski atthe letterhead address or by telephone at 409-766-6381.Sincerely,Ke yy JaynsýýChief, Compliance SectionEnclosuresCc:U.S. Regulatory Commissionc/o Jessie Muir M/S T6-D3211555 Rockville PikeRockville, MD 20852 eV K~ca~ MII.gWd.-Waters (24,639.1 Linear Feet)EJ Wetlands (17.6 Acres)-]- Project Review Area (1406.5 Acres)=reliminary Jurisdictional DeterminationSouth Texas Project Units 3 & 4Matagorda County, TXW#1C fSWG-2007-786May 13, 20090 750 1,500 3.000P"4Cbo, NADI 193 SU"PUMJt.,.

In order to protect the integrity of a discovery the STPNOC Supervisor will take appropriate steps toprotect the discovery site by ceasing all work in an area of stoppage adequate to provide for the totalsecurity, protection, and integrity of the resource. Vehicles, equipment, and unauthorized personnelwill not be permitted to traverse the discovery site. Work in the immediate area will not resume untiltreatment of the discovery has been completed following provisions for treating archaeologicalcultural material contained in this addendum.C. The STPNOC Environmental Manager, arrange for the site to be evaluated by a qualified culturalresources management specialist. If the cultural resources find is determined to be significant; thecultural resource specialist/archaeologist or consulting archaeologist will immediately contact theTHC to seek consultation regarding the National Register eligibility of any further discovery.Construction will be halted within the immediate area of the discovery and the scene will be protecteduntil consultation to determine the appropriate course of action has been conducted. The STPNOCSupervisor may direct construction away from cultural resources to work in other areas prior tocontacting the concerned parties.D. Where cultural resources are encountered during construction, but additional project effects to theresources are not anticipated, project construction may continue while documentation and assessmentof the cultural resources proceed. The total area of work stoppage will be adequate to provide for thesecurity, protection, and integrity of the discovery. Construction may continue at the discoverylocation only after the process outlined in this addendum is followed and STPNOC and THC aresatisfied the caveats of Section 106 of the National Historic Preservation Act have been met.E. Routine documentation of newly discovered cultural material should not impact constructionschedules. Where complex or extensive cultural remains are encountered, the STPNOCEnvironmental Manager and archaeological personnel will determine the appropriate level ofdocumentation and treatment of the resource through consultation with THC.F. STPNOC will ensure the proper documentation and assessment of any discovered cultural resources incooperation with a contracted consultant and THC. All prehistoric and historic cultural materialdiscovered will be recorded by a professional archaeologist using standard techniques. Wherewarranted in the opinion of the qualified cultural resources professional, site overviews, features, andartifacts will be photographed; stratigraphic profiles and soil/sediment descriptions will be preparedfor subsurface exposures. Discovery locations will be documented on scaled site plans and sitelocation maps.G. All prehistoric and historic artifacts collected from the surface and from probes and excavation unitswill be analyzed, catalogued, and temporarily curated. Ultimate disposition of cultural materials willbe determined in consultation with the THC.H. Within 90 days of concluding fieldwork, a technical report describing any and all monitoring andresultant archaeological excavations will be provided to the STPNOC Environmental Manager. TheSTPNOC Environmental Manager will forward the report to the THC.I. If assessment activity exposes human remains (burials, isolated teeth, or bones) all defined proceduresoutlined in the following section will be followed. OPGP03-ZO-0025 Rev. 13 Page 50 of 50Site Environmental ComplianceAddendum 5 Unanticipated Discovery of Cultural Resources Page 3 of 3Special Procedures for the Discovery of Human Skeletal MaterialAny human skeletal remains regardless of ethnic origin, which may be discovered during this project willat all times be treated with dignity and respect.A. During all project operations if any STPNOC employee or any of the contractors or subcontractorsbelieves that they have made an unanticipated discovery of human skeletal remains, all work adjacentto the discovery shall cease. The area of work stoppage will be adequate to provide for the totalsecurity, protection, and integrity of the human skeletal remains. No persons other than the proper lawenforcement personnel, STPNOC Cultural Resource Consultant(s), and the THC will be authorizeddirect access to the discovery location after the area is secured. If the remains are determined to be ofNative American ancestry thorough consultation with the THC, tribal access will only be allowed tothe designated representative(s) of the affected tribes'. Coordination for tribal member access must gothrough the designated tribal representative. The strict control of a burial location is mandated toinsure the safety and integrity of the burial feature and remains.B. Representatives of STPNOC are responsible for taking appropriate steps to protect the discovery.. Theimmediate area will be secured to a distance adequate to provide for the total security, protection, andintegrity of the resource. Vehicles, equipment, and unauthorized personnel will not be permitted totraverse or enter the discovery site.C. STPNOC will immediately call the Matagorda County Sheriff's Office and will ensure that anindividual competent and qualified to identify human skeletal remains is present. If possible, theethnic origin, or ancestry, of the discovered human remains will be determined through consultationwith the THC, County Coroner and the THC-determined affected tribe. The local law enforcementofficial may arrange for a representative of the county coroner's office to assist the STPNOC CulturalResource Staff in the examination of the discovery and together will determine whether it should betreated as a crime scene or as a human burial of Native American ancestry.D. If disinterment of Native American human remains becomes necessary, the consulting parties, whichwill include STPNOC, THC, and the affected tribe(s), will jointly determine the final custodian of thehuman skeletal remains for reinterment.E. STPNOC and/or the FHWA will make a good faith effort at accommodating requests from theaffected tribe(s) to be present after they are notified of discoveries, and prior to the implementation ofmitigation measures related to the human remains.

I hope the following information meets your needs." Austin Energy (AE) last performed ROW vegetation management in 2006 with extensive ROWdearing of brush and trees in the 100 foot ROW." Austin Energy is scheduled to perform vegetation maintenance on our four-year cycle, scheduledmaintenance this year, 2010 We are scheduled to begin field work on this ROW sometime inMarch, 2010* AE has completed our property ownership research and we are beginning our field patrols of theROW to assess vegetation conditions. Preliminary findings are that the ROW vegetationconditions are still very good, with good clearances and access." AE has an aggressive and thorough vegetation management program utilizing herbicideapplications, tree removals and mowing to control vegetation to prevent outages and maintainfacility access." AE Forestry Transmission Program is managed according to AE Tree Pruning and Line ClearanceSpecifications (attached). The methods of ROW maintenance that more direct our practices onthis ROW are outlined on page 4, item B of these specifications. This is paraphrased as "anyvegetation in the AE right-of-way that has the potential to grow into the clearance zone (20 feetminimum clearance near poles or structures and 25 feet at mid-span) of the transmissionconductors, should be targeted for removal... As right of way conditions allow, the right of waymay be kept clear of woody vegetation by mowing or other appropriate methods." (specificallyherbicide applications)." AE's specifies removal of trees that have the potential of growing into the clearance zonesurrounding the conductors, which is a minimum of 20 to 25 feet; and in most cases much moreclearance distance is achieved; which allows for four to five years of above-average tree growth.These distances are in addition to the 9.4 feet minimum distance for 345kV from the IEEE 5162003 Clearances (table attached)." AE Transmission Construction and Maintenance personnel patrol this transmission ROW twice ayear and report any vegetation concerns to AE Transmission Forestry Section for immediateattention for vegetation maintenance.Please let me know if this is the appropriate information you need. If you require any additionalsupporting information, please don't hesitate to contact me via e-mail with the specifics needed, or call meat one of the phone numbers given below.Thank you,Carl SchattenbergUtility ForesterAustin Energy(512) 322-6931 (Office)(512) 801-4997 (Cell)1/7/20 10 TER-4. Austin Energy Tree Pruning and T-line Clearance Specs, November 7,2005, [STPLR-448] /4-- STPL_- 446AUSTIN ENERGYTREE PRUNING AND LINE CLEARANCE SPECIFICATIONSINTRODUCTIONThese Tree Pruning Specifications and Requirements, together with the American National StandardsInstitute ANSI A300, "Standard for Tree Care Operations" (as approved May 22, 2001, or subsequentrevision), shall govern all pruning and/or removal of any plant or tree growth interfering with the safeoperation of any City of Austin Energy (AE) facility. Where any discrepancy or contradiction existsbetween this contract document and the ANSI standard, the requirements of the contract document shallprevail.The primary goal for the line clearance tree pruning program is to maintain a safe and reliable electricaltransmission and distribution system. These specifications and requirements prescribe arboriculturalstandards to ensure consistent tree pruning practices, and efficient, economical line clearancemaintenance. They shall provide a basis for determining whether tree pruning is necessary orappropriate, and shall dictate the arboricultural methods to be adhered to in the performance of the workactivity described in this document.The AE is obliged and committed to compliance with the terms and conditions of City of Austin GeneralDevelopment Permit No. GP-05-0000.AEU, and any subsequent extension or renewal. The Vendor shallbe familiar with these terms and conditions, and will ensure that no violations occur as a result of theVendor's actions.All tree work shall conform to approved principles and techniques of modern arboriculture. Proper lineclearance tree pruning shall direct tree growth away from electrical conductors and facilities, extendpruning cycles, and reduce the overall amount of future pruning work required. The AE shall determinethe appropriate distances between all plant or tree growth and electrical facilities. Because of thedifficulty in developing line clearance tree pruning policies which would cover all circumstances, the AEreserves the right to assess, on a case-by-case basis, any special situations where the strict applicationof these specifications and requirements might be impractical or inappropriate.I. PRUNING SPECIFICATIONSThe following specifications shall apply to all tree pruning unless otherwise specified herein. For thepurpose of this line clearance tree pruning contract, a tree shall be considered to be a self-supportingwoody perennial plant, having a trunk diameter of no less than two inches (2") at maturity, measured atfour and one-half (4-1/2) feet (Qiameter at Breast Height, or DBH), with one (1) or more branchesdeveloping from the stem or trunk. Plants containing multiple trunks or stems, each of which exceeds twoinches (2") in diameter (DBH), will be considered to be one (1) tree when those stems originate from acommon root crown, or are less than six inches (6") apart.A) The most important technique in pruning a tree is the collar cut. This term refers to the final pruningcut to remove a limb just outside the raised portion (branch collar) of the branch junction with thetrunk or another limb. A proper collar cut will minimize the exposed surface area of the cut surface.All limb or branch removals shall be performed using the collar cut method.B) When removing a lateral branch at its point of origin on the trunk or parent limb, the final cut shall bemade in branch tissue close to the trunk or parent limb, without cutting into the branch bark ridge orcollar, or leaving a stub. (ANSI A300 Standard 5.3.2 and 5.3.3).C) When removing a dead branch, the final cut shall be made just outside the collar of live tissue. If thecollar has grown out along the branch stub, only the dead stub shall be removed. The live collar shallbe left intact and uninjured. (ANSI A300 Standard, 5.3.5).D) No stub and/or flush cuts shall be left on the trunk or supporting branch unless specifically requestedby the property owner and specifically approved by the AE, prior to the removal of branch or limb.11/07/05 1 Specifications and GuidelinesOriginal TreeSpec 97 05 Update.doc AUSTIN ENERGYTREE PRUNING AND LINE CLEARANCE SPECIFICATIONSE) Old stubs from prior stub cuts that have re-sprouted and re-grown into the electrical conductor cleararea shall be removed to the branch collar of the stubbed-off limb, or may be pruned to a lateral limb,behind the stub, large enough to assume the terminal role, consistent with these pruningspecifications and requirements.F) The three-cut method should be used in order to prevent ripping or peeling of the bark on the trunk orparent stem from which the limb is removed.G) When a leader, dominate or co-dominate stem is to be removed, it shall be removed back to a laterallimb or branch no less than one-third (1/3) of the diameter of the portion being removed.H) When removal of an entire lateral limb back to the branch collar on the parent stem would removeexcessive branch tissue and foliage, and is not necessary to obtain the required line clearance, theleader of a lateral limb may be pruned to a lateral limb large enough to assume the terminal role. Inmaking a thinning cut in this instance, the final cut shall be beyond the branch bark ridge of thecrotch.I) All final lateral pruning shall be concluded at a branch collar on the supporting branches or trunksgrowing away from the electrical facility, so that the growth of the tree is directed away from electricalfacilities (directional pruning).J) Directional pruning is used to redirect side growth away from the electrical facilities. Limbs growingtowards the facilities are removed to appropriate limbs or trunk to train the tree away from theelectrical facilities.K) Drop crotch pruning is used to reduce the height of a tree by removing dominant or co-dominantstems in the center of the crown of the tree and direct growth away from the electric lines overhead.This method of line clearance pruning is most often used when the conductors are involved with thecenter of the tree crown. Limbs should be cut at the branch bark ridge, consistent with properarboricultural techniques, as detailed in B) above.L) All tree pruning wounds and other wounds caused by AE operations on oak trees shall be treatedpromptly with a thin but complete covering of an approved non-phytotoxic tree wound dressing.Wounds on oaks shall be treated before moving to another part of the tree, and prior to descendingthe tree. All oak stumps shall be painted with a tree wound dressing, as required on all oak wounds.No other tree species shall be painted unless specifically requested by the property owner, ordirected by the AE. (ANSI A300 Standard, 5.4.1).M) Rips and peels are not acceptable and shall be avoided, but if they occur, tree wound dressing maybe applied, as a cosmetic treatment only. Tree wound dressing may be applied as a cosmetictreatment on large wounds.N) To help prevent the spread of various types of tree diseases, all cutting tools (hand and powered)shall be surface disinfected with a seventy percent (70%) or higher solution of alcohol and water.Other disinfectants, such as Lysol and 50% chlorine bleach (sodium hypochlorite) and water solutionmay be substituted. Disinfectants shall be applied prior to commencing any pruning on the job site,and immediately after pruning oaks suspected to be infected with oak wilt in a designated diseasedarea.11/07/05 2 Specifications and GuidelinesOriginal TreeSpec 97 05 Update.doc AUSTIN ENERGYTREE PRUNING AND LINE CLEARANCE SPECIFICATIONSII. LINE CLEARANCELine clearance distances attained during tree pruning operations shall vary depending on the power linevoltage and the type of trees encountered. Higher voltage power lines require greater clearances. Fastgrowing trees shall be pruned to provide more clearance from electrical facilities than slow growing trees.The tree pruning operation shall provide clearance as appropriate for the line voltage and average growthrate of the affected trees, with the overall objective of achieving a minimum four (4) to five (5) yearpruning cycle.Line clearing shall begin only after careful consideration of the position occupied by the electric facilityrelative to the adjacent trees, and the growth rate of the affected trees.The clearances specified shall be consistently achieved. Special efforts shall be undertaken forreasonable resolution of any property owner objections or disputes.DISTRIBUTION FACILITIESIf the pruning required to obtain adequate clearance from an electric facility (i.e., leaning pole, low poleheight, sagging wire) would significantly affect the shape of the tree, the Vendor shall consult with the AEInspector to determine if the electric facilities can be adjusted to reduce the pruning required.Telephone or TV Cable facilities shall not be considered in determining line clearances.A) Primary conductors 600 volts to 12,500 volts -Minimum clearance shall be 6 to 8 feet, dependingon the tree species. Additional line clearance may be required to allow for the annual growth of thevegetation to maintain a 4 -5 year right-of-way maintenance cycle. The Vendor shall remove alloverhang above the top of the pole or primary conductor, or as directed by the AE.B) Secondary conductors less than 600 volts -Minimum clearance shall be 4 to 6 feet, dependingupon tree species. Additional line clearance may be required to allow for the annual growth of thevegetation to maintain a 4 -5 year right-of-way maintenance cycle.C) Service drops and streetlight conductors -2 to 3 feet, depending upon tree species. Servicedrops and street light conductors will only be pruned when Vendor crews are working in the area andlimbs are applying pressure to the facilities. The cost effectiveness of re-routing the wires will beconsidered before any line clearance work is completed. Tree removals will not be done on thesewire types.D) Poles, Guy Wires, Down Guys, Transformers, and Other Electric Facilities -The Vendor shallfree guy wires and down guys of weight, strain or altered position caused by contact with tree limbs orbranches. Guy wires, down guys and poles shall be free of vines. The AE, at its sole discretion, shalldetermine whether to cut and/or remove all vines or plant growth obstructing or limiting accesses, atthe base of, or on the affected electric facility.E) Street lights and night watchmen lights will not be part of the Utility Forestry Section lineclearance program. Any trees that need to be maintained for illumination purposed are solely theresponsibility of the owner or PARD.F) New Construction -The customer requesting service will be asked to be responsible for clearing alltrees in the ground easement to meet the requirements of the AE. All required tree removal permitswill be the responsibility of the customer and will be completed by the customer. The AE's Vendorwill be responsible for pruning all trees to establish necessary aerial clearance to provide safe andreliable electric service.11/07/05 3 Specifications and GuidelinesOriginal TreeSpec 97 05 Update.doc AUSTIN ENERGYTREE PRUNING AND LINE CLEARANCE SPECIFICATIONSTRANSMISSION FACILITIES -69,000 volts to 345,000 voltsWherever possible, the following transmission specifications shall be obtained by the Contractor. TheVendor shall inform AE personnel where these clearances can not be obtained.A) Trees and other vegetation will be pruned or removed to allow for a minimum of 20 feet of clearancenear all transmission conductors, poles or structures and a minimum of 25 feet at mid-span, to allowfor sag and sway. Additional line clearance may be required to allow for the annual growth of thevegetation to maintain a 4 -5 year right-of-way maintenance cycle. The AE, at its sole discretion,shall determine whether to cut and/or remove plant growth obstructing access at the base of thetransmission facility.B) In rural or undeveloped areas, as right of way conditions allow, any vegetation in the AE right-of-waythat has the potential to grow into the clearance zone (20 feet minimum clearance near poles orstructures and 25 feet at mid-span) of the transmission conductors, should be targeted for removal.Any vegetation in the AE right-of-way, or beneath the transmission conductors, that has the potentialto obstruct right of way access, or access to the transmission structure should be targeted forremoval. This includes trees growing beneath conductors and structures, vegetation blocking AEaccess gates and any vines on facilities. As right of way conditions allow, the right of way may bekept clear of woody vegetation by mowing or other appropriate methods.C) The Contractor shall remove all overhang above the top of the transmission conductors andstructures.D) A corridor will be maintained free of any woody plants to provide access by AE to the transmissionfacilities to repair and maintain the transmission grid.E) Any hazardous tree within the right-of-way that poses a hazard to any transmission facility, at the solediscretion of the AE, should be pruned or removed to mitigate the hazard. Any vegetation outside ofthe AE right-of-way that presents a hazard to the transmission facilities will be pruned back orremoved to the limits of the right-of-way.F) Poles, Guy Wires, Down Guys, and Other Transmission Facilities -The Vendor shall clear tree limbsor branches a minimum of 4 -6 feet from guy wires and down guys. The Contractor shall cut and/ortreat all vines growing on all transmission facilities. The AE, at its sole discretion, shall determinewhether to cut and/or remove plant growth obstructing access at the base of the transmission facility.F) In designated Balcones Canyonlands Preserve (BCP) bird habitat areas, proposed line clearancework must be submitted for the BCP review process for approval. Access corridors shall not exceed20 feet in width, unless to allow for clearance of truck booms. In accordance with the review process,line clearing is limited to the removal of fast growing species directly below transmission conductorsand pruning to provide at least 20 feet of clearance from conductors. Line clearance activity, otherthan emergency response, is prohibited in these habitat areas between March 1 and September 1.G) In any other area determined to be endangered species habitat by the US Fish & Wildlife Service,anyproposed line clearance work must be submitted for review prior to initiating work. Work scheduling,and certain clearing methods may be restricted by the US Fish & Wildlife Service.TREE REMOVALSTree removals are an unavoidable component of a utility forestry program. Problem trees and othervegetation often need to be removed from near electrical facilities to correct a hazardous situation,improve service reliability, and to provide access to the electrical facilities. When considering a treeremoval, the AE personnel or Vendor needs to consider the condition and specie of the tree, itsplacement and the priority of the tree removal. Every reasonable effort should be made to communicate11/07/05 4 Specifications and GuidelinesOriginal TreeSpec 97 05 Update.doc AUSTIN ENERGYTREE PRUNING AND LINE CLEARANCE SPECIFICATIONSwith the customer to obtain informed consent prior to removal of these problem trees from near theelectrical facilities.TREE REMOVAL CANDIDATESA) Dead, dying, diseased, or unstable trees (danger trees) which presents a danger to utility facilities orwhere a tree is destabilizing utility structures.B) A tree that is totally involved with the utility facility and can not be effectively pruned to provideadequate clearance from electrical facilities and the continued health of the tree. Such trees locatednear schools, or other public areas where a person could easily climb and contact the electricalfacilities present a serious safety concern.C) Fast-growing trees that may interfere with the electrical facilities, present a safety concern and/orhinder service reliability before the next tree maintenance cycle.D) Trees with dominant terminal leaders (pines, etc.) that can not be directionally pruned away from theelectrical facilitiesE) Immature trees that can be economically removed from near the electrical facilities to prevent futurereliability concernTREE REMOVAL CONDITIONSA) With the informed consent of the property owner or customer, removal of trees should be limited tothe area within the distribution easement or up to ten feet either side of distribution conductors andwithin transmission rights of way, unless a dangerous situation exists.B) A tree removal should be cost effective to the AE. A tree removal should be limited to twice the timeit would take to prune the tree. Exceptions would include trees near the main line circuits and dangertrees,C) Low-growing trees, which have a mature height of less than 25 feet, should not be removed unlessdirected by the AE for access and clearance around electrical facilities.D) Stumps shall be cut as close to the ground as possible. All oak tree stumps shall be painted with atree wound dressing, as required on all oak wounds. With customer consent, the stump will betreated with an EPA -approved herbicide to prevent re-sprouting.E) All proposed removals of trees 8" in diameter at breast height (DBH), or larger, must be reported byAE or Vendor field personnel to the Utility Forester for review and submittal to the City Environmentalcontacts at least two days prior to removal. Any proposed removals of treesl9" DBH, or larger, mustbe have a signed permit approved prior to pruning 33% or more of the canopy, or prior to removal ofthe tree, as required by the City Protected Tree Ordinance.INDIVIDUAL REQUESTS FOR ASSISTANCE- TICKETSThe AE receives numerous requests from customers to prune trees on their property near the electricalfacilities. The Utility Forestry Section is responsible for evaluating and taking appropriate actions onthese requests. The following shall apply to individual requests for pruning trees near to AE facilities.General SpecificationsEach request shall be evaluated individually, and may require a site visit by AE or Vendor personnel.11/07/05 5 Specifications and GuidelinesOriginal TreeSpec 97 05 Update.doc AUSTIN ENERGYTREE PRUNING AND LINE CLEARANCE SPECIFICATIONSA) If is determined that the customer request should be granted on an expedited basis, at the directionof Owner, the Vendor shall schedule and perform the work as soon as possible.B) The customer may be directed, at the option of the AE, to request a temporary disconnection of theirservice drop to allow safe tree pruning or removal by the customer, without the services of theVendor.C) The Vendor will be required to provide the AE with information on work order status for customerrequest jobs on a weekly basis.TOPPING FOR REMOVALProperty owners will often request AE assistance with tree removals near the electrical facilities. TheInspector or Vendor will evaluate the removal and determine if its removal by the property owner wouldconstitute a threat to the electrical facilities. In cases where a threat is perceived, the Inspector or Vendorwill work with the property owner to remove any parts of the tree that are in danger of contacting theelectrical facilities. It is the property owner's responsibility to remove the rest of the tree. Listed beloware the AE procedures.A) At the request of a property owner, with notification and approval of appropriate City Environmentalauthorities, the AE will direct the Vendor to remove only those branches which could come intocontact with the electrical facilities for the property owner to safely complete the tree removal.B) If necessary, AE facilities shall be temporarily removed or de-energized by the AE to permit saferemoval of the tree by the property owner.C) For removal of trees sixty inches (60") or more in circumference, or nineteen inches (19") or more indiameter (DBH), measured four and one-half (4-1/2) feet from ground level, the property owner isrequired, under City ordinance, to obtain an approved tree removal permit from the City Arborist'soffice. The Vendor shall not commence work prior to verification of the required permit.DISPOSAL OF PRUNED MATERIALWood chips are usually disposed of at the specified locations agreed to by the Owner and Vendor. Anagreement between the City Parks Department and Austin Energy will allow the Vendor to dispose ofchips at designated park locations. The following shall apply to cleanup, removal and disposal of prunedmaterial.A) The Vendor shall remove and dispose of only those trees, plants or portions of trees pruned by theVendor. When possible, removal and cleanup shall be completed daily by the Vendor before leavingthe job site. No cut limbs, woody debris, trash or other debris will be left on the premises without priorconsent of the property owner and responsible AE personnel. No woody debris, trash or otherdebris will be left in roads or drainage ditches.B) Removal and disposal of portions of any tree pruned by the property owner, or portions of any treenot affecting the electrical facilities, are the responsibilities of the property owner.C) The Vendor shall promptly clean up and remove all debris produced by AE personnel performingroutine or emergency tree pruning when instructed by appropriate AE personnel.D) The Vendor should make every effort to find alternate dump sites for chips or woods, with propertyowner approval, near the work location if at all possible. Any alternate disposal sites must meet anyenvironmental restrictions for the particular area and must not be left in roads, ditches or adverselyaffect drainage or access.11/07/05 6 Specifications and GuidelinesOriginal TreeSpec 97 05 Update.doc & 'AUSTIN ENERGYTREE PRUNING AND LINE CLEARANCE SPECIFICATIONSE) Oak wood from Spanish, Blackjack or red oak trees suspected of being infected with oak wilt diseaseshall not be left on site and shall be disposed of at the appropriate location.F) Any woody debris generated by the crews that can not be disposed of near the work site shall betransported to a temporary dumpsite provided by the Vendor. Logs and chips must be separated atthe site or at the temporary dumpsite for transportation to the appropriate dumpsite.G) Any non-woody debris (paper, plastic, cans, metal, etc.) shall be disposed of separately from thewoody debris.11/07/05Original TreeSpec 97 05 Update.doc7Specifications and Guidelines TER-5.

The objective of Phase Two studies is todetermine the number and type of aquatic organisms which are (a) impinged onthe revolving screens and (b) entrained by the reservoir fill pumps during thefilling of the main cooling reservoir. Phase One studies, conducted in1975-76, resulted in predictions of impingement and entrainment losses andPhase Two is designed to confirm the accuracy of those predictions. Samplingmethods remain the same as in Phase One. Phase One samples were collected atfour locations in the Colorado River, designated as Stations 1,2,3 and 5.Phase Two samples are to be collected only at Station 2, i.e., in the ColoradoRiver adjacent to the Reservoir Makeup Pumping Facility (RMPF) and in theSiltation Basin, the body of water located between the RMPF revolving screenstructure and the pump structure.On 11 July 1983, cooling reservoir filling operations began at the SouthTexas Project in Matagorda County, Texas. This report presents data collectedduring July, August and September 1983. After the third week of September, nofurther reservoir filling occurred in 1983 or through the first six months of1984. The data presented in the following report therefore constitute theinformation collected during the period July, 1983, through June, 1984.1 METHODSSAMPLING SCHEDULE AND STATIONSThe aquatic ecology study is divided into two distinct types of studies,impingement and entrainment, requiring different gear types and methodologies.The impingement study is conducted on the revolving screen structure, whichextends 423.5 ft along the west bank of the Colorado River at River Mile 14.6.The entrainment study is conducted at two locations: 1) in the Colorado Riveradjacent to and slightly downstream of the screen structure, and 2) in thesiltation basin between the pump structure and the submerged weir.FIELD AND LABORATORY PROGRAMSImpingementImpingement samples are collected within one week of the start of eachpumping period and weekly thereafter as long as pumping continues. Each week,three samples are collected over a 24-hr period. Prior to the start of eachrevolving screen sample, 2 of the 24 screens are selected at random and runfor 15 min to clean them of accumulated debris. The two screens are thensampled for a 30-min period by placing a tight-fitting dip net with 1/4-inmesh at the lower end of the screenwash trough and filtering all the organismswashed off the screens. While the sample is being collected, hydrology andwater quality parameters are recorded from the siltation basin behind thescreen structure. Surface and bottom readings of water temperature (°C),conductivity (millimhos/cm) and dissolved oxygen (ppm) and a surface readingof pH are recorded as are the number and size of RMPF pumps operating at the2 time of sample collection. The Colorado River flow (cfs) is also noted on thefield data sheets.After the two screens have been sampled for 30 min, the collecting net ischecked for fish, shrimp and crabs. Those found are placed in a plasticsample jar, preserved with 10% buffered formalin and taken to the laboratoryfor identification and enumeration. In the laboratory, each sample is rinsed,sorted by species and the total weight by species and individual lengths(standard length for fish, total for shrimp) or widths (carapace width forcrabs) are recorded. If over 50 individuals of the same species occur in asample, a subsample of 50 is measured. The remainder are counted and theweight of the total is recorded.EntrainmentEntrainment sampling commences within one week of the start of eachcooling reservoir filling period and is conducted at least every other week aslong as pumping continues. A set of samples is collected every 6 hrs over a24-hr period. During the months of March-May and August-December, sampling isdone weekly when the salinity at the -8.5 ft level in the Colorado Riverexceeds 3 ppt. Salinity probes have been mounted on a piling in the rivernear the RMPF at that depth and are connected to a continuous chart recorderto provide a record of salinity fluctuations. The recorder is checked dailyand, if the 3 ppt level is exceeded, the appropriate personnel are notified toinitiate sampling. During the initial months of pumping in 1983,instrumentation and procedural problems resulted in the total loss of3 continuous salinity data. However, salinity data was collected in conjuctionwith biological sampling and is discussed later in this report.Colorado RiverPrior to the start of collection of each set of biological samples,surface and bottom readings of conductivity (which was later converted tosalinity), water temperature and dissolved oxygen were taken at mid-channel ofthe Colorado River near the northern end of the RMPF screen structure.Additional conductivity readings were made at 5-ft intervals between thesurface and bottom. The primary instrument used to measure these parameterswas a Hydrolab Model 8002 with 8100 series probe assembly. A Yellow SpringsInstrument Co. Model 51A temperature and dissolved oxygen meter and anAmerican Optical Co. hand-held refractometer were used as a backup to theprimary system. Surface pH was measured with a portable Altex Model 531153 pHmeter and water transparency was determined using a 200-mm diameter Secchidisc.A 0.5-m diameter, 3:1 (length:mouth diameter) plankton net with 0.5-mmsquare mesh was used to collect plankton samples at mid-channel of theColorado River. Samples were collected at the surface, mid-depth (10 ft) andnear the bottom. The plankton net was attached to a sled to keep the netabout 4 inches above the bottom during towing for the bottom sample. AGeneral Oceanics Model 2030 digital flowmeter mounted in the center of the netmouth was used to calculate the volume of water filtered during each tow. Theflowmeter reading was recorded prior to and at the conclusion of each plankton4 tow. Each mid-channel sample was collected by lowering the net to theappropriate depth with the boat in a stationary position. All tows were madein the direction of river flow, i.e. north to south. Each tow startedapproximately 50 yds upstream of the RMPF and continued to a pointapproximately 50 yds downstream of the RMPF. Bottom tows were made at aslower forward speed than either the mid-depth or surface tows to insure thatthe net sled remained on the bottom. A wire-angle indicator and graduatedtowline were used to verify the depth from which the mid-depth sample wascollected. This was maintained at about 10 ft as the depth of the channel isapproximately 20 ft. The surface sample was taken by towing the net with theupper edge of the net mouth a few inches below the water's surface. At theend of each tow, the boat was held stationary in the river while the net wasquickly brought to the surface. This was done in an effort to minimizecontamination of the sample due to the net being towed upward through thewater column above the level being sampled. At the end of each tow the netwas rinsed from the outside to wash the sample contents into the cod endbucket. The sample was then placed in a plastic jar, labeled and preservedwith 5% formalin. Rose Bengal was added to each sample several days beforesample workup to facilitate visual separation of the organisms from trash anddetritus.A 0.5-m diameter, 3:1 (length:mouth diameter) plankton net with 0.5-mmsquare mesh equipped with a General Oceanics model 2030 digital flowmeter anda cable depressor was used to collect oblique-tow plankton samples near thewest shoreline of the Colorado River. Before each sample was collected, theflowmeter reading was recorded. After lowering the net to the bottom at the5 north end of the RMPF screen structure, the net was towed downstream while thetowline and attached plankton net was slowly reeled in. When the net reachedthe surface, the boat was stopped, the net raised and the flowmeter readingrecorded. After rinsing the net down from the outside, the sample was placedin a plastic jar, labeled and preserved with 5% buffered formalin. RoseBengal was added to each sample as described above.A 20-ft (headrope length) otter trawl, with 1 1/4-in stretched mesh in theupper end and 3/8-in stretched mesh in the cod end, was towed on the bottomparallel to shore at mid-channel of the Colorado River to determine thespecies composition and abundance of the nekton (fish and macroinvertebrates).Tows were of 5 min duration and were made in the direction of water flow.Each trawl tow began approximately 50 yds upstream of the RMPF. Each samplewas emptied into a large tub and inspected for larger specimens of fish andinvertebrates. These were identitied, weighed, measured and returned to theriver. The remainder of the sample was preserved in 10% formalin and taken tothe laboratory for analysis.Shallow shoreline populations of fish and invertebrates in the vicinity ofthe RMPF were sampled by use of a two-man bag seine. A 20-ft long x 6-ft highx 6-ft deep seine, with 1/2-in stretched mesh in the body and 1/4-in acewebbing in the bag, was pulled for a distance of approximately 75 ft along thewest shore line downstream of the RMPF. The seine collections were made bypulling the seine in the upstream direction (south to north) as the currenthelps in holding the bag of the seine open. Specimens taken by seining werehandled as described above for trawl samples.6 Siltation BasinThe method originally chosen to sample organisms from the siltation basinwas to pump water to the top of the RMPF pump structure deck where it would befiltered through an ichthyoplankton net. During the first two collectingtrips, on 14-15 July and 27-28 July 1983, repeated attempts were made tocollect samples by this method. However, the pump could not overcome the headinvolved. Therefore, no siltation basin samples were collected on thosedates. On the third trip, surface plankton samples were collected byhand-towing a 0.5-m (mouth diameter) ichthyoplankton net, having 0.5-mm squaremesh, parallel to the front wall of the pump structure. Hand-towing the net ata deeper level in the water was not attempted because of the danger of the netbeing pulled into the mouth of one of the operating pumps. Towing the net byboat in the siltation basin was not possible because of the small size of thebasin and the presence of several submerged obstructions.7 RESULTS AND DISCUSSIONHYDROLOGY AND WATER QUALITYWater temperature, pH, turbidity (Secchi disc) and dissolved oxygen at theColorado River station are given in Table 1. Tables 2 & 3 show theconductivity measurements and the derived salinity values. Water temperature,salinity, dissolved oxygen and pH in the RMPF siltation basin are given inTable 4. Water temperature, conductivity, salinity, dissolved oxygen and pHat the RMPF revolving screens are given in Table 5.On 14-15 July a wedge of salt water was present in the Colorado Riverextending up to about 10 to 15 ft below the surface. The wedge was 2.3 to3.0 C warmer than the overlying fresh water and was low in dissolved oxygen(maximum of 0.9 ppm).On 27-28 July no salt wedge was present (0.9 ppt at bottom) and freshoxygenated water extended to the bottom. A salt wedge was re-established on9-10 August and 15-16 September extending up to 10 to 15 ft from the surfaceand even up to 5 ft on 9 August. The bottom oxygen was again very low onthese two days (0.1 to 0.5 ppm).In the RMPF siltation basin the water quality of the surface water wassimilar to that of the surface water in the river on the same dates.At the revolving screens the water quality was similar to that of theriver at comparable depths on the same dates.8 River flow during the sampling periods is shown in Table 6 and the dailyvolume of water pumped into the cooling reservoir during July -September,1983 is shown in Table 7.MACROZOOPLANKTON AND ICHTHYOPLANKTONSamples collected by 0.5-m plankton net in the Colorado River yielded 49taxa of invertebrates and 10 taxa of vertebrates, (Table 8). The dominantinvertebrate forms were cladocerans, or water fleas, which are all freshwaterorganisms; copepods, both freshwater and estuarine-marine in origin; andMalacostraca, consisting of estuarine mysid shrimp, freshwater and estuarineamphipods, estuarine-marine penaeids (commercial shrimp), freshwater andestuarine carideans (grass and river shrimp) and various species of crabs.The fish were represented by as many as 10 taxa, but they were rarely a majorcomponent of any single sample. On some occasions, however, the bay anchovydid occur in large numbers.Tables 9-12 show the temporal and spatial variations in density ofinvertebrates collected from the Colorado River on each of the four samplingtrips. The largest total numbers of organisms were collected in mid-depth,bottom and oblique tows and also innight collections. Higher densitiesappear to be closely related to the presence of a salt wedge at the -10 ftlevel and deeper, as occurred on 9-10 August and 15-16 September (See Table3). A salt wedge also occurred on 14-15 July, but no bottom samples werecollected on that trip because the bottom plankton net was lost during thefirst tow of the day.9 The most ubiquitous species, as well as the most abundant, was the zoealarval stage of the xanthid mud crab, Rhithropanopeus harrisii. The secondmost abundant forms were the zoeal and postlarval stages of the ghost shrimp,Callianassa spp. The postlarval stage of the brown shrimp, Penaeus aztecus,and the'white shrimp, P. setiferus, and the megalops and juvenile stages ofthe blue crab, Callinectes sapidus, were collected only sporadically and neverin very high densities. It is possible that some of the crab megalopsrepresented the non-commercial pygmy blue crab, C. similis, which isimpossible to differentiate from C. sapidus at this stage of development.A list of the common and scientific names of the egg, larval and juvenilestages of the fish taxa collected from both the Colorado River and thesiltation basin is found in Table 13.Tables 14-17 show the changes in abundance which were observed, bothtemporally and spatially, in the Colorado River ichthyoplankton during thestudy period. The most notable trends seen in this limited amount of dataare: (a) the relatively small numbers of ichthyoplankters from the surfaceand oblique tows compared to the large numbers from the mid-depth and bottomtows and (b) the greater numbers of larval and juvenile fish in samples col-lected at night, regardless of depth. The bay anchovy was the most abundantspecies, due primarily to its peak in abundance on 27-28 July. One possibleexplanation for the anchovy's apparent high level of abundance is due to thelow salinity observed from surface to bottom on those dates (see Table 3).The bay anchovy is an estuarine species preferring salinities in excess of 10ppt, and the fact they were caught in such large numbers during a period of10 high freshwater flow and salinities less than 1 ppt indicates they were understress. This made them more susceptible to capture by a plankton net thanthey would be under normal conditions, when they are probably just asabundant, especially in the salt wedge (mid-depth to the bottom). The onlyother taxa collected regularly were two species of gobies and one categorycalled Gobiidae larvae. The darter goby, Gobionellus boleosoma, and the nakedgoby, Gobiosoma bosci, are both estuarine, mid-depth to bottom dwellingspecies which are common over mud substrates in all Texas estuaries. Thelarvae of the two genera are indistinguishable below about 5 mm, thusresulting in the unidentified Gobiidae larvae category.Because ichthyoplankton were taken in such small numbers in the samplescollected in the siltation basin, they are included with the invertebrates onthe tables showing temporal changes in abundance of organisms at this location(Tables 18 and 19). Penaeus setiferus (white shrimp) postlarvae peaked inabundance during the night on both collecting dates, but were otherwise foundonly in low densities. Macrobrachium ohione, one of the river shrimps, andRhithropanopeus harrisii, a xanthid mud crab, were the most abundant speciesin the basin. M. ohione were much more abundant in the basin than they werein the Colorado River on the same dates (see Tables 11 and 12). This iseasily explained by the fact that river shrimp zoeae and juveniles, the lifestages collected in these samples, prefer shoreline areas with protectivevegetation cover to open river channel habitat. The front wall of the RMPFpump structure, along which the plankton net was towed, afforded a semblanceof shoreline habitat by accumulating floating pieces of wood, dead grasses andother types of vegetative material. Further evidence for the shoreline nature11 of the siltation basin sampling location is the occurrence of Gambusiaaffinis, a shallow shoreline species of fish known as the mosquitofish, onboth the 9-10 August and 15-16 September collecting dates. The megalops andjuvenile life stages of the blue crab, Callinectes sapidus, were the onlyother taxa occurring in fairly high densities, and this was only on 9-10August when they also peaked in abundance in river samples. Notable by itsabsence from the siltation basin were Callianassa spp. zoeae, which were veryabundant in the river. They are, however, primarily a mid-depth and bottomdwelling group and the sampling technique used was not adequate for detectingtheir presence.12 MACROINVERTEBRATES AND FISHTrawl and seine samples yielded eight macroinvertebrate species, fiveshrimp, two crabs and a crayfish (Table 20 and Tables 21-28). The grassshrimp, Palaemonetes paludosus, the river shrimp, Macrobrachium ohione, andthe crayfish, Procambarus blandingi acutus, are freshwater animals whereas thethree penaeid shrimp and the two crabs are estuarine and marine. The bluecrab, Callinectes sapidus, however, is tolerant ot fresh water and is known tomigrate far upstream in rivers.The river shrimp was the most common invertebrate (818) closely followedby the white shrimp, Peneaus setiferus (760). The majority of the rivershrimp were caught in trawls on 27-28 July while the majority of the whiteshrimp were caught in seines on 15-16 September.Twenty-nine species of fish were collected in trawl and seine samples. Ofthese, four species are freshwater and 25 are estuarine or marine. Thegreatest number of species of fish (16) as well as the greatest number ofindividuals (3697) were recorded from the trawls taken on 27-28 July.However, because the majority (97.7%) of the fish caught that day were bayanchovies, Anchoa mitchilli, the diversity for that day is low. Except forthe large number of anchovies on this one day, the catches in the trawls andseines were similar in number of species and total number of individualstaken.13 Impingement samples yielded 6 macroinvertebrate taxa, 2 of which werefound only in the impingement samples (Tables 29-33). Palaemonid shrimpdominated the species list (4 of 6 taxa), but the majority of individuals wereblue crabs. With few exceptions the individuals were small, less than 30 mmin length (or width in the case of crabs).Three species of fish were collected in the impingement samples, eachrepresented by one individual. The green sunfish, Lepomis cyanellus, was theonly freshwater fish and the only fish species caught by impingement that wasnot caught by trawl or seine.14 TABLE 1TEMPORAL VARIATIONS IN TEMPERATURE,

First cut at manpower loading for PIP # 081270- Spent Fuel management ProjectLast Thursday (Aug 11) there was a Pre-PRT review of the DRAFT for PIP #081270. The PIP waspresented to PRT on Wednesday (Aug 17).At the Pre-PRT meeting we recognized some changes to the first DRAFT manpower loadings. Some butnot all of these were incorporated into the PIP that was presented to PRT.Today I met with Joe Nagle and further changes were identified. Two changes were to re-assign "FuelMovers- Craft labor" and "Vendor Install the SFP Racks" from cost center 932 to the Refueling Team costcenter.With these changes, the following NFAD activities are identified in the latest working version of PIP #081270:* NFAD and DED are jointly identified for Design work support (to the vendor) for Installing the SFPRack Modules 12 and 16. This activity is assigned 556 hours for Ul in 2012 and 444 hour for U2 in2012." NFAD is the responsible group for the Criticality Analysis work to be done by a vendor to beselected. The funding is $100,000 in 2012 and $25,000 in 2013; this should be corrected to$250,000 in 2013." NFAD is the responsible group for the NRC's review of the Criticality Analysis. The funding is$200,000 in 2014 and $200,000 in 2015.* NFAD is the responsible group for the Poison Insert design work to be done by a vendor to beselected. The funding is $1,000,000 in 2015 which is identified as "Contingency"; and $1,000,000in 2016.These PIP funding amounts are consistent with NFAD's inputs to date.NFAD needs to consider additional NFAD manpower support that will be required for the on-going spentfuel management work, and which budgets (PIP, baseline, or other) will be used.8/18/2011 AQ-2.

The initial report (McAden et al. 1984)covered the period July 1983 -June 1984. This report presents data from thesampling period July -December 1984. Due to limited pumping during thisperiod, only one set of samples was collected.METHODSAll stations, schedules and methods employed were the same as thosedescribed in the initial report (McAden et al. 1984). A malfunction of the pHmeter precluded pH measurements during sampling.RESULTS AND DISCUSSIONHYDROLOGY AND WATER QUALITYWater temperature, turbidity and dissolved oxygen data from the ColoradoRiver station are shown in Table 1. Conductivity values are given in Table 2,and salinity values are given in Table 3. Water temperature, salinity anddissolved oxygen data from the Reservoir Makeup Pumping Facility (RMPF)siltation basin are given in Table 4. Water temperature, salinity anddissolved oxygen data from the RMPF revolving screens are given in Table 5.1 On 5-6 September a salt wedge was present in the Colorado River, extendingto within 5-10 ft of the surface. The wedge was up to 3.0 C warmer than thelow salinity surface water and contained low dissolved oxygen levels (maximum0.8 ppm at the bottom).Surface water quality in the RMPF siltation basin was similar to that ofthe surface water in the river. Bottom water quality measurements were notmade in the siltation basin.Surface water quality at the revolving screens was similar to the surfacewater quality in the river. However, bottom salinity at the screens was lower(as much as 6.3 ppt) than salinities at comparable river depths.River flow during the sampling period is shown in Table 6 and the dailyvolume of water pumped into the reservoir during July-December 1984 is shownin Table 7.MACROZOOPLANKTON AND ICHTHYOPLANKTONSamples collected by 0.5-m plankton net yielded 29 taxa of invertebratesand 7 taxa of vertebrates (Table 8). The most abundant invertebrates werejellyfish (medusae), copepods (especially Acartia tonsa and Oithona spp.),barnacle nauplii, the zoeae of the brackish water shrimps Palaemonetes spp.and Callianassa spp. and the zoeae of the brackish water crab Rhithropanopeusharrisii. All of the vertebrate taxa consisted of larval and juvenile stagesof both freshwater and estuarine fishes. A single sunfish larva (FamilyCentrarchidae) constituted the freshwater component of the ichthyoplanktonsamples, whereas the bay anchovy and at least two species of gobies dominatedthe estuarine taxa.2 Table 9 shows the variations in macrozooplankton abundance over the 24-hrsample period on 5-6 September 1984 in the Colorado River. The largest totalnumbers of organisms were taken in samples collected at mid-depth and in theoblique tows. Considerably smaller numbers of taxa, as well as numbers withintaxa, were collected at the surface and near the bottom. The reasons forthese spatial differences in abundance can be seen in the hydrological andwater quality measurements made at the times of sample collection(Tables 1-3). There was a layer of very low salinity water at the surface,which contained a paucity of both taxa and numbers of individuals within taxa.The reason for the relative scarcity of zooplankton near the bottom of theriver is the critically low dissolved oxygen levels near the river bottom(Table 1).By far the most commonly found and most abundant of the river zooplanktontaxa was the xanthid mud crab, Rhithropanopeus harrisii. Other abundant formswere jellyfish medusae and the zoeal stages of the ghost shrimp, Callianassaspp. Relatively low numbers of the commercial white shrimp, Penaeussetiferus, and the megalops stage of the blue crab, Callinectes spp., weretaken, although Callinectes spp. megalops did occur at a high density in the0300-hr oblique sample. It is possible that this taxon consisted of both thecommercial blue crab, C. sapidus, and the noncommercial pygmy blue crab, C.similis.A list of the common and scientific names of the larval and juvenilestages of fish taxa collected from both the Colorado River and the siltationbasin is found in Table 10.3 Table 11 shows the temporal and spatial variations in ichthyoplanktonabundance in the Colorado River. The data are too limited to draw anymeaningful conclusions, except to note the total absence of ichthyoplanktonnear the bottom. This is understandable given the low dissolved oxygen levelsnoted in the earlier discussion of macrozooplankton abundance.Table 12 depicts the changes in abundance of macrozooplankton andichthyoplankton over the sampling period. As in the river samples, the zoealstage of the xanthid mud crab, Rhithropanopeus harrisii, was the most abundanttaxon, but unlike the river samples, highest densities occurred during thehours of daylight. The reasons for this are unclear, because siltation basinsamples were collected at the surface and zooplankton abundance in surfacesamples is typically lowest in the daytime. Another commonly occurring,albeit in low densities, taxon was the parasitic fish louse, Argulus spp. 'Nopenaeid shrimp or blue crab larvae were taken from the siltation basin, andonly one ichthyoplankter, an unidentified yolksac larva.MACROINVERTEBRATES AND FISHRepresentatives of 27 species were captured in seine and revolving screensamples during the study (Table 13), but no organisms were captured in thetrawl samples. Critically low dissolved oxygen levels at the bottom of theriver (Table 1) appear to be the limiting factor.4 Six (6) species of macroinvertebrates, including 5 species of shrimp and 1crab, were taken in seine samples (Table 14). Macrobrachium ohione, a smallriver shrimp, was the only freshwater representative, while the estuarine/marine white shrimp, Penaeus setiferus, was the most abundant invertebrate(643 caught).Twenty species of vertebrates, all of which were fish, were caught in theseine samples (Table 14). Of these, only the spotted gar, Lepisosteusocculatus, is freshwater, with the remainder being estuarine and marine. Thefish most commonly caught was the bay anchovy, Anchoa mitchilli (170).Impingement samples (Table 15) yielded 4 macroinvertebrate species, one ofwhich was the pink shrimp, Penaeus duorarum, found only in the impingementsamples. The total catch was 15 individuals. In general, the animals weresmall, 5-64 mm in length.5 REFERENCES CITEDMcAden, D.C., G.M. Greene and W.B. Baker, Jr. 1984. Report #1.

Dear Mr. Gangluff:
I received your letter dated May 24, 2007, requesting that the Main Cooling Reservoir (MCR) bedesignated as a closed-cycle recirculating system and as not water in the state.The Texas Commission on Environmental Quality (TCEQ) does not have an official method of"designating" a facility's operation as a closed-cycle recirculating system. However, we have reviewedthe information you submitted and based on our best professional judgement, we consider your facility tobe a closed-cycle recirculating system. As mentioned in your letter, the federal rule governing the 316(b)Phase II cooling water intakes is currently in the process of being suspended. For the time being,implementation of the 316(b) requirements will be based on best professional judgement (BPJ) andsubject to EPA Region VI review.We also concur that the Main Cooling Reservoir (MCR) at your facility does not meet the definition ofwater in the state.If you have any questions, please contact me at (512) 239-2369.Sincerely,Kelly Holligan, LeaderIndustrial TeamWater Quality DivisionKH/jpP.O.

Dear Mr. Holligan:
Thank you for meeting with my staff on May 15, 2007 to discuss the South Texas ProjectElectric Generating Station (STPEGS) cooling reservoir and other wastewater discharge pennitissues. Based on our discussion, STP Nuclear Operating Company (STPNOC) is submitting thefollowing information regarding the Main Cooling Reservoir (MCR) and the applicability of theregulations for cooling water intake structures. We are confident that the South Texas ProjectStation (STP) complies with the regulation by employing a closed-cycle recirculating coolingsystem as defined in 40 CFR §125.93. Pursuant to 40 CFR §125.94(a)(1)(i), cooling water flowfor this facility is commensurate with a closed-cycle recirculating cooling system, asdemonstrated below. Additional technical information is included in letters dated March 7, 2005and August 18, 2005 previously submitted to the Texas Commission on Environmental Quality(TCEQ).STP is located on 12,220-acres in Matagorda County, approximately 15 miles southwest of BayCity along the west bank of the Colorado River. The facility consists of two electric-generatingunits, which share a closed-cycle recirculating cooling reservoir. Water from the MCR is passedthrough the cooling loops of both units then returned to the MCR for heat dissipation beforecycling back through the cooling systems.The MCR is a perched, off-channel, on-site industrial cooling impoundment of approximately7,000 acres, impounding over 202,600 acre-feet of cooling water at its maximum operating level.Dikes are installed in the MCR that channel the water flow to maximize circulation time for heatdissipation before the water is recirculated back to the generating units. Blowdown from theMCR to the Colorado River has not occurred since March 1997. Should blowdown be requiredit would occur through an underground pipe that discharges back into the Colorado River. Thispoint is designated as Outfall 001 in the TPDES Permit No. 01908. The MCR is also equippedwith a gated spillway for emergency use. The MCR is not a "water of the U.S." as defined at 40CFR § 122.2. The MCR is not considered a "water of the State" based on internal and externaloutfall designations in the permit. The MCR is on private property and exists solely for Mr. Kelly HolliganMay 24, 2007Page 2industrial cooling. It is not a publicly managed water body and has no recreational uses. Thegeneral public has never had access to the MCR nor is any planned in the foreseeable future.The only sources of new water to the MCR are direct rainfall and make-up water divertedperiodically from the Colorado River, primarily at high river flows. Water from tile ColoradoRiver is pumped approximately I mile via a 108 inch pipe to the MCR. To protect inflows duringlow river flow conditions, the water right for STP includes a special provision to limit diversionfrom the Colorado River to 55% of the flow over 300 cubic feet per second, to protect inflowsduring low river flow conditions. Currently, the intake consists of trash racks, rotating screenswith 3/8 inch mesh and 4 pumps. In addition, the reservoir makeup pumping facility has thefollowing design:" The traveling water screens are flush with the river shoreline;" The maximum approach velocity to the traveling water screens is 0.5 feet per second;" Fish passageways were constructed in the wing walls between the traveling screens tofacilitate fish migration parallel to the screen surfaces; and" A sluice and discharge line was installed for the purpose of returning all impingedorganisms directly to the river, downstream of the intake structure, immediately afterbeing backwashed from the screens.The pumps are operated intermittently based on reservoir level, river flow, and the operability ofthe makeup pumping facility. A cooling reservoir evaporates less water per unit of heatdissipated than a cooling tower, thus dissolved solids build up more slowly over time. This iscomplemented by the designed seepage from the MCR, which maintains the structural integrityof the reservoir embankment. Rainfall further dilutes the dissolved solids in the MCR. Thesefactors minimize the blowdown and make-up required to maintain MCR water quality. As aresult, intake water flow for cooling purposes at STP reflects best technology available (closed-cycle recirculating systems) for minimizing adverse environmental impact.As was discussed in the May 15, 2007 meeting, several provisions of the Phase II rule are in theprocess of being suspended by the U.S. Environmental Protection Agency and the RegionalAdministrators have been authorized to review the applicability of the rule on a case by casebasis using Best Professional Judgment. Based on that authorization and the informritionprovided, STPNOC is requesting that TCEQ designate the MCR as a closed-cycle recirculatingsystem. We are also requesting concurrence that the MCR does not meet the definition of a"water of the State". If you have any questions or require additional information, please contactMs. S. L. Dannbardt at (361) 972-8328.Sincerely,R. A.

Of thethree gear types used to sample the ECP, only the trawl was productive in catching fish. A total of5,589 fish representing two species, sheepshead minnow (Cyprinodon variegatus) and sailfinmolly (Poecilia latipinna), were caught during the study. Sheepshead minnows and sailfin molliesare both common species in Texas and are indigenous to coastal streams, rivers, and estuaries.Mean sizes for both species ranged from 27 to 62 mm total length (TL) (1 inch to 2.5 inches)and were evenly distributed across all sample sections. Sheepshead minnows were mostabundant in quadrant Q2A and sailfin mollies were more abundant in Q4A near the intakestructure. Relative abundance for both species was evenly distributed across quadrants Q2 and03. The total number of fish caught in quadrant Q1, near the discharge, was significantly lowerthan the total number of fish caught in quadrants Q2, Q3, and Q4. Total abundance estimatesderived from the total number of fish caught, total amount of trawling effort and total area covered,indicate that a population of 535,000 fish comprised of both species exists in the ECP. Thisestimate is an extrapolation from the data collected and is based on assumptions about theexisting populations and the sample gear used. Therefore, interpretation of such data may resultin an over estimate of total abundance. It is, however, our belief that fish populations in the ECPare not overabundant.Fish congregating at or near the intake structures may be attributed to the availability of food,structure or cover, and protection from environmental stresses. Under normal operating andenvironment conditions, both species would be expected to avoid the higher water velocitiesfound immediately adjacent to the intake structure. Excessive impingement and entrainment oforganisms is a factor more of how the pumps are operated rather than the total number of fishpresent in the ECP. Prevention of fish congregating in the intake structures may be achieved bymaintaining a constant flow rate at the intake screens and in the pump wells and/or by changingthe chemical composition of the water in the pump wells. If pumps must be shut down, adding05727-800/STPEGS/Fish Population Study May, 2002iv EM~.chemicals such as rotenone, chlorine or other chemicals in the pump wells may create waterconditions unsuitable for fish and prevent them from congregating in the area.Based on the data we collected during this study and discussion with site personnel whoobserved the size/species distribution associated with the Essential Cooling Water Pump 1Cstrainer clogging, the existing population in the ECP is not expected to cause a recurrence of thiscondition as long as precautionary measures are taken to preclude fish from utilizing thescreen/pump well areas during pump shut down and start up.

1.0 INTRODUCTION
This document presents a summarized report for the Fish Population Study performed on the 47acre Essential Cooling Pond (ECP) at the South Texas Project Electric Generating Station(STPEGS), Wadsworth, Texas. The objective of this study was to determine baselinecharacteristics of the fish population (Nekton Population) in the 47 acre ECP and to providemanagement recommendations for monitoring and controlling said fish population. Section 1presents the materials and methods arranged categorically. Section 2 discusses the datacollected. Section 3 presents a discussion of the results and provides managementrecommendations.1.1 MATERIALS AND METHODSThe fish population study was conducted in accordance with techniques described inFISHERIES TECHNIQUES by Nielson and Johnson (1983), published by the AmericanFisheries Society.The ECP was divided into four quadrants (Q1, Q2, Q3, Q4) based on linear shorelinemeasurements of approximately 1000 feet (Figure 1). Each quadrant was divided into twoapproximately equal sections and labeled as section A or B for each quadrant starting in aclockwise direction from the discharge structure around to the intake structure. A total of eightsections were identified in the ECP. A GARMIN 48 handheld GPS unit was used to verifysample quadrants and sections. Latitude and longitude coordinates were recorded for allsamples collected. Per the request of site management (Pre-Job Brief) no gill nets or hoop netswere set within 1000 feet of the intake structure. Gill net and hoop net sets designated for Q4were set on or immediately adjacent to the 1000-foot line in Q3 (Figure 2). Hydrological andnekton sampling methodology are detailed below.'4WC,-VIJOOI rLaorIbi, rupuiaiiui, ctuuy 17- -ý i" /p al tUJIL UI 1 1.2 HYDROLOGICAL DATAA YSI Model 58 temperature/oxygen meter was used to measure water temperature (00) anddissolved oxygen (mg/I). These parameters were measured at the start and end of eachsampling day. Both parameters were measured at mid-water depth. Water depths werereported by site personnel to be approximately 9 feet to 12 feet at the pump intake structure.South Texas Project's Nuclear Operating Company Chemistry/Environmental personnelprovided additional water quality data. These data included pH and conductivity. Conductivitywas converted to salinity [parts per thousand (ppt)] using a conversion nomogram. Hydrologicaldata collected during this study were used only as base-line reference points for currentconditions in the ECP.1.3 NEKTONThe following gear types were used to establish sample size (numbers) and species (kinds) of fishpresent in the ECP. These gear types are routinely used by fisheries biologists for conductingtotal fish population assessments.Trawl samples were collected in the ECP using a 6.1 m (20 ft) otter trawl measured along thehead-rope from shackle to shackle. A trawl door measuring 1.2 m long and 0.6 m tall (48 inch x21 inch) was attached to each wing of the net. Each door was shackled to a 30.4-m (100 ft) longbridal and then attached to the stern of the towing vessel. The trawl was comprised of 3.8-cm (13/8-inch) stretched-nylon mesh and the cod end of the trawl was covered by a 6.3-mm (1/4 inch)nylon mesh sock. Trawl samples were towed for ten minutes behind a 16-foot center-consoleboat powered by a 40 hp motor. In the initial work scope, tow speed was set at 3.0 knots for allsamples; however, trawls were towed at approximately 2.0 knots in an effort to minimize netavoidance caused by engine prop wash. A total of eight trawl samples were collected (2 per eachQuadrant). All finfish species were measured for total length (TL) to the nearest mm. If more than50 individuals of a species occurred in sample, a random subsample of 50 was measured and theremaining individuals were counted to obtain a total number for each species.UD~ CI'tAJO~Q I rcuors~,I r~JIJut4utJ,, oiuuy 2 tviay ctnJc057 7- -F -O rEl/isl rpuI~u oln i u iy2Maey =w Gill net samples were collected in the ECP using four (4) experimental gill nets constructed ofmonofilament mesh. Each net was 91.4-m (300 ft) long, 2-m (6 ft) deep and was comprised offour separate 22.9-m (75-foot) sections of 1.3-, 2.5-, 5.1-, and 7.6-cm (1/2-,1- , 2-, and 3-inch)stretched mesh connected in ascending mesh sizes. Two 15-lb concrete blocks were used toanchor each gill net to the bottom and one 15-lb block was used to anchor each gill net on theshore. Gill nets were set in randomly selected sections within each quadrant. Quadrant 4 gillnet was set on or immediately adjacent to the 1000-foot boundary line separating Quadrant 3and Quadrant 4 (the net was essentially set in Quadrant 3) per the Pre-Job Brief requirementthat no nets be set within 1000 ft of the intake structure. Gill nets were set starting shortlybefore sunset (6:18 pm) and were retrieved within 2 hours after sunrise (6:38 am) on thefollowing morning. No fish were captured in any of the gill net sets. Had fish been captured inthe gill nets, they would have been sorted according to each section of mesh, identified byspecies, and measured for TL to the nearest millimeter.Four hoop net samples were set in the ECP using hoop nets constructed of fiberglass rings and cottonnetting material. Each net measured 3.6-m (12-ft) in length, had an opening hoop diameter of 0.91--m(3-ft), and was covered by 5.1-cm (2-inch) stretched cotton mesh netting dipped in nylon coating.Hoop nets were set in a randomly selected section within each quadrant. Quadrant 4 hoop net wasset on or immediately adjacent to the 1000-foot boundary line separating Quadrant 3 and Quadrant 4(the net was essentially set in Quadrant 3) per the Pre-Job Brief requirement that no nets be set within1000-foot of the intake structure. Each net was baited with a fish attractant (one can of dog food,recommended by local commercial fishermen). Hoop nets were set with the opening facing downcurrent, anchored by two 15-lb concrete blocks and marked with buoys for easy retrieval. No fish werecaptured in any of the hoop net sets. Had fish been captured in the hoop nets, they would have beensorted by species and measured for TL to the nearest millimeter.1.4 DATA ANALYSISData analysis was conducted for eight trawl samples and included the following parameters:total number of fish for each species captured, calculation of average size and range of sizes foreach species, cumulative length frequencies for each species, and an estimate of relativeabundance for each species.U572/-0t-UU/: IH'tU6:/F-ISn Population Study3 Relative abundance was calculated by dividing the total number of each species captured bythe amount of effort (time) the gear was used. This value represents catch-per-unit-effort(CPUE). CPUE is directly proportional to the total abundance of fish in the stock and can beused to make further statistical analyses such as comparing catch rates from quadrant toquadrant or from year to year.Additional statistical analyses were performed in order to test for homogeneity between samplevariances (t-Test: Two-Sample Assuming Equal Variances) and to test for variability amongsample means (ANOVA) (Alder and Roessler, 1977; Ott and Mendenhall, 1993).n QJQTDCr_'QIC;ýk 0;ý-I.C- C-A, M _F04ay 2.0 RESULTSThe results of our study are presented below.2.1 SAMPLE LOCATIONSSample locations for gill nets, hoop nets, and trawls are shown in Figure 2. Latitude and longitudecoordinates for each sample site are presented in Table 1. A total of 16 samples were collectedduring this study. Hydrological and nekton data are presented below.2.2 HYDROLOGICAL DATAHydrological data (water temperature, dissolved oxygen, salinity, and pH) are presented inTable 2.Water temperature during the study was 20.5 'C at the start of the study and 20.4 °C at thecompletion of the study.Dissolved oxygen (DO) readings during the study period ranged from 7.8 mg/I to 9.8 mg/I. DOreadings were the highest in Quadrant 1 and the lowest in Quadrant 4. DO readings decreasedincrementally from quadrant to quadrant as the sample stations moved further away from thedischarge structure. This is to be expected, based on the turbulence near the discharge servingas an aerator. Dissolved oxygen readings were higher on day 1 than day 2 for all samplestations. Lowest dissolved oxygen readings were recorded on the second day of the study duringthe retrieval of the gill nets and hoop nets. A reading of 7.8 mg/I was recorded at Q4. Quadrant 1dissolved oxygen readings on day 2 dropped down to 8.0 mg/l.STPEGS' Project Manager provided additional water quality data. Their data during the studyperiod indicated the pH to range from 8.87 to 8.89 and conductivity to be 1114 qS/cm to 1131.qS/cm. Conversion of conductivity readings to salinity parts per thousand (ppt) indicated thatsalinity was <2.0 ppt. Additional water quality data provided by STPEGS'sChemistry/Environmental personnel indicated that pH in the ECP has fluctuated between 8.3 and9.5 since November 1999 (Appendix A).UOICt~tAJOIOI rcuoIrIbII rupumirurr otuuy 5 gv~y ~uueU5727-ýSII Ipu atiUI on U y5M~ay 2002, 2.3 NEKTONA total of 5,589 fish representing 2 species was caught during this study (Table 3). Speciescollected during sampling were Cyprinodon variegatus, (Sheepshead minnow) and Poecilialatipinna, (Sailfin molly). The trawl was the only gear type to capture fish. A discussion of eachsampling gear is detailed below.2.3.1 TrawlsA total of eight (8) trawl samples-were collected on the 47 acre ECP. Trawl samples werecollected from eight different sections (Q1A, Q1 B, Q2A, Q2B, Q3A, Q3B, Q4A, and Q4B) of theECP (Figure 2). Each section was trawled for 10 minutes at a tow speed of 2 knots. However,trawl sample Q4A was trawled for 8 minutes due to a twist in the trawl door that occurred duringsampling. No attempt was made to redo the sample due to the proximity to the intake structure(within 1000 ft) and because the area was already covered during the initial trawl samplecollection. Trawling twice in the same sample area during the same sample period could resultin even fewer fish being caught. CPUE was adjusted according to different trawl times. A two-sample t-statistic was run to test for difference in sample population means between Q4A andQ4B. T-statistic results indicated there was no significant (95% level) difference between thetwo sample population means; further indicating there was no bias introduced by the shortenedtrawl time.Total catch (by number and catch rate) for each section is presented in Table 3. Section Q2Ahad the largest number of fish captured of all sections sampled. Section Q1 B had the fewestnumber of fish captured. ANOVA test results across all eight samples indicated that there wasno significant (95% level) difference between sample means, thus indicating that all eight trawlsamples were homogeneous.Total fish caught by quadrant indicates a significantly lower number of fish were caught in Q1 ascompared to the other three quadrants. However, the total number of fish caught in Q2, Q3, andQ4 were not significantly different from one another.UO~~t-LflJN~I rtu~,rwfI ropuwtivri otutiy 6 May ~UU~-opu t~onl ou y6may 2002=: Catch rates for each section and quadrant are listed in Table 4. Catch rates by speciesindicates that sheepshead minnows were most prevalent in section Q2A and least abundant inQ1B. Sailfin mollies were most prevalent in section Q4A and least abundant in sections QIA,Q1 B, and Q3A. Species relative abundance was most evenly distributed across Q2 and Q3.The abundance of sailfin mollies in Q4 can be attributed to a number of different components;however, the availability of food and habitat (structure) as it relates to the intake structure aremost likely the key components. Mean sizes for both species were the same across all samplesections (Table 5). The widest range was for sailfin mollies, which ranged from 27 to 62 mm TL(1 inch to 2.5 inches). The abundance of sailfin mollies was most prevalent in the 40 to 55 mmTL (1.5 to 2.25 inches) size class. Cumulative length frequencies for both species arepresented in Figures 3 and 4.2.3.2 Gill NetsFour experimental gill nets were set in the ECP; one net per quadrant in randomly selectedsections of each quadrant. No fish were captured in any of the gill net samples. Gill net fishingtimes (effort) are listed in Table 6. Average fishing time for gill nets was 13.24 hours.2.3.3 Hoop NetsFour hoop nets were set in the ECP; one net per quadrant in randomly selected sections of eachquadrant. No fish were captured in any of the hoop net samples. Hoop net fishing times (effort)are listed in Table 6. Average fishing time for hoop nets was 14.01 hours.u~LeI-LAJ~ I rtu~irisn rupui~uun ~iuuy 7 IVIdY CUUC05727-00/1 IE~is opulatton Sludy7Maliy 2LqJ EKr RNITA.3.0 DISCUSSIONDiscussions of the results for our study and management recommendations are detailed below.3.1 RESULTSHydrological data were collected during this study for the purpose of establishing baseline waterquality parameters in the ECP. No statistical correlation between fish abundance and waterquality was performed using these data. Any inferences concerning possible correlation wouldbe speculative at best and would require more data.Trawling was the only successful method of capturing fish in the ECP. Trawl samples collectedin each of the four quadrants contained fish. Although only two species were captured, the totalnumber and catch rate for each species indicates these fish are prevalent in all areas of theECP. Quadrant 1 was the only quadrant sampled which had a significant difference in totalnumber of fish. This fact can most likely be attributed to the amount of water being dischargedby the plant into quadrant 1 of the ECP. Despite the fact that most fish species are attracted towater currents, flow rates from the discharge structure into Quadrant 1 are judged to be highenough to discourage most fish from residing in this area, specifically smaller fish such as thosecollected in our samples. In fact, it may be great enough to flush them from the area or limittheir presence to the perimeter of the pond. A similar difference in distribution could beexpected directly in front of the intake structure. However, it would be impossible to discernwhere exactly the fish in our study were caught because trawling methods used covered bothshoreline and open water areas. Furthermore, trawl samples were not collected immediately infront of the intake structure for safety reasons.Data from the four gill net and four hoop net samples indicate the absence of larger fish speciesin the ECP. Although it is possible the sampling gears may have been selective for species andsizes, it is highly unlikely that all eight samples would have resulted in zero catches if fish of anysize over 3 inches were present in the ECP. Furthermore, the lack of species diversity collectedduring trawl samples indicates no other species were present in the pond. Trawling is typicallyselective for the size of the individual captured, but not selective for species.-~a -C.JUC0512 -0viyo I s PoL/InFpulaionl~ oudy8May 2002 EKR.The lack of species diversity has been further validated by data collected by STPEGS sitepersonnel. Their preliminary data indicated that only sheepshead minnows and sailfin mollieswere the species present (Appendix B). Their data were collected using baited minnow traps ator near the intake structure and the discharge structure. Comparative analysis of catch ratesbetween gears is very difficult. Although no direct correlation between STPEGS data and thedata we collected was conducted, the use of minnow traps to collect data as it pertains torelative abundance, size distribution, and species composition could prove valuable assumingproper sampling techniques are followed. These would include standardizing sample stations,sample times (soak time), placement depths, and baiting techniques to name a few.Data analysis of the eight trawl samples indicated the fish populations sampled werehomogeneous. Mean sizes of fish captured in all four quadrants were similar for both species.Data analysis of sample size and catch rates indicate that Q1 was significantly different fromQ2, Q3, and Q4. This significant difference can most likely be attributed to the velocity water inQI. Total abundance of fish was determined based on total number of fish caught andestimates of area covered during trawl samples.In an effort to estimate the total number of fish in the ECP, we made several basic assumptions,the validity of which we cannot verify based on a single set of samples. We have taken a "worstcase" approach, which could overestimate the actual population size.We have assumed that there is a uniform distribution of fish throughout the ECP, both in depthand in width. We have also assumed that our trawling effort covered 5% of the total watervolume and caught all fish that encountered the gear. Therefore, we collected 5% of the totalpopulation during our sampling effort. Based on these assumptions and extrapolation of thedata, there is a population of 535,000 fish in the ECP, comprised of both species. However, weknow that the fish are not uniformly distributed (Q1 was statistically different than Q2, Q3, Q4 inour data) and the size of the area sampled was not precisely 5% of the total area.Consequently, the actual population size could be less than this. As both species are morecommonly found in shallow water or shoreline areas rather than open- or deep-water areas, it ishighly probable that fish collected in the trawls were captured only from the shoreline zones. Ifs opua on u9,vay this is true, the total population would be expected to be less than what we estimated, as theestimate is based on the total volume, not just the shallow shoreline area. Having determinedthat this is likely the case, we do not feel that either species is overpopulated.Congregation of these species at or near the intake structure may be attributed to the availabilityof food, structure or cover, and protection from environmental stresses such as extensive coldspells. During normal environmental conditions, fish in the ECP should tend to seek out naturalhabitats or niches. The occurrence of fish in the intake wells during cold weather conditions is anatural response. Fish will seek protected waters that provide relief from existing environmentalconditions. The intake structure could provide such habitat. This could be particularly truewhen pumps are shutdown, creating a calm water refuge in the screen/pump wells. If this infact happens, one would expect an increase in impingement when pumps are turned back on.Under normal operating and environmental conditions, both species would be expected to avoidthe higher water velocities found immediately adjacent to the intake structure. Therefore, webelieve that excessive impingement could occur only when pumps are shut down for anextended time period and fish either seek shelter within the intake structure pump wells, orutilize it as new habitat due to additional food availability and/or cover. Preventing fish fromcongregating in the intake structures may be achieved by maintaining a constant flow ratethrough the screens and/or by changing the chemical composition of the water around thepumps. This may be accomplished by dispersing chemicals, such as rotenone, chlorine, orother chemicals, directly into the water in the pump wells prior to restarting of pumps.The species captured from the ECP, Cyprinodon variegatus (sheepshead minnow) and Poecilialatipinna (sailfin molly) are common to brackish waters of the Texas Gulf Coast and bothspecies are found in the many rivers and streams that enter the Texas bays. Make-up water forthe ECP was from the main cooling reservoir, which originally came from the adjacent ColoradoRiver. Both species are common in this river system (Texas Parks and Wildlife, personalcommunication).Although the possible sources of these fish were not evaluated in this study, ENSR is of theopinion that fish were introduced during the initial filling of the ECP. This means of introduction05127-0=6/ I Ftt;:gw-Sn' Hopulation Zjtucly10may 2002 is highly probable if surface water was used to fill the pond. In the case of the sheepsheadminnow, eggs could have also been carried in on the feet, legs, and plumage of various wadingand aquatic birds as their eggs are semi-adhesive and are capable of adhering to thesesurfaces. This mechanism of introduction is not deemed possible with sailfin mollies.Of the two species captured, sheepshead minnows were more prevalent by a ratio of 50:1.Mean sizes of both species caught in the ECP were within normal length ranges and themajority of fish were either subadult or adults. Maximum length for sheepshead minnows was55 mm TL (2.25 inches) and the maximum length for sailfin mollies was 62 mm TL (2.6 inches).No fish less than 20 mm TL were caught. The lack of juvenile fish in the samples is most likelya result of mesh size used on the trawl. A smaller mesh size would need to be used to capturethe juvenile fish.Sheepshead minnows are a very hardy species. They are tolerable of a wide range of waterquality conditions and are commonly found in marine, brackish, and freshwater habitats. Theyprefer shallow water habitats and are most common along sandy or silty shorelines.Sheepshead minnows can reach a maximum size of 3 inches and have an average life span ofabout three years. They are very prolific breeders reaching sexual maturity by the time they areone year old. They are egg layers and will spawn multiple times during the spring and summermonths allowing them to populate an area in a very short period of time. They will layapproximately 20-25 eggs per spawn and their eggs are semi-adhesive. Sheepshead minnowsare detritivores and prefer to feed over substrates of silt and detritus. They are known to burrowinto soft substrate during adverse conditions, such as large temperature fluctuations andextreme tidal changes; which enables them to survive these situations.Sailfin mollies are primarily a brackish water species. They are known to be very adaptable inthe wild and are commonly found in freshwater rivers and streams as well as saltwaterenvironments. They feed mostly on algae and other plant matter that is available. Sailfinmollies are surface dwelling and swim freely in open areas, and they are particular to watersthat are high in calcium (hard water) and more alkaline waters ranging in pH from 7.5 to 8.5.Sailfin mollies are typically 4 to 6 inches in length and have an average life span of 3 years.Po ulation StuA, Ma 2002F1"1 ENsRThey are live bearers, giving birth to 20 to 80 fully developed young in each brood. The femalesailfin molly will give birth once every six to eight weeks during the breeding season (April toSeptember). They can produce young year round; however, they normally do not give birthwhen water temperatures are below 21.1°C.Beneficial aspects of these fish species in the ECP were not evaluated during our study.However, both species are known to feed on algae as well as other plant matter such as detritusand therefore could have a positive impact on the ECP. Furthermore, the ability of these fish tomaintain healthy populations in the ECP is a good indication that the present ecosystem isproviding necessary food, habitat, and water quality. It should be noted however, that currentturbidity levels in the ECP are too high to allow establishment of large quantities of algaethroughout the entire pond. Most of the algae should be isolated along the shoreline whereavailable sunlight can penetrate the water and allow algae to grow. It is our opinion that if algaelevels were to get to problematic levels in the ECP, it would require a larger population than thecurrent population of fish to alleviate the problem.3.2 MANAGEMENT RECOMMENDATIONSManagement of undesirable fish populations is achieved by using three basic methods:chemical, biological, and mechanical. Chemical and biological means are favored overmechanical controls for most species of fishes (Kohler and Hubert, 1993). Before determiningwhat management approach will be most effective, several factors should be considered andevaluated. These include cost, size of the water body, water temperature and quality, targetspecies, environmental concerns, and location of the water body (Kohler and Hubert, 1993).The use of chemical methods to control undesirable fish populations has become a very populartool for fisheries managers. Most chemicals are easily applied, require a short time to getresults, and very inexpensive when compared to other methods. Chemical methods aretypically used to treat an entire system where the goal is the removal of all fish. Chemicals canalso be used to partially treat particular sections, or spawning sites of selected fishes in an effortU~727-COWi I PL(~S/HSfl I~opuIation ~tudy 12 May ~UO205727-008/Zi 1 PE(35/I-I$1 Population 12may z200 EN, .to remove a major portion of the population. This approach usually requires the introduction ofa predatory species to forage on the remaining residual population.Chemicals used as fish toxicants must meet the needs* of the fishery managers. The toxicantshould be specific for the targeted species, easy and safe to apply, degrade to a harmlessconstituent, must be effective over a broad range of water quality conditions, and be registeredfor use in the aquatic environment (Lennon et al. 1970).There are four approved and registered toxicants in the United States, two of which areregistered for "general" use and will be discussed; rotenone and Antimycin. Fisheries managerscommonly use both of these toxicants.Rotenone is the most common fish toxicant used by fisheries managers. Rotenone works byshutting down the oxygen transfer system in fish, which eventually causes suffocation. Thechemical is safe and effective when applied properly and has almost no adverse affect on birdsor mammals. Rotenone comes in liquid and powder formulations and can be dispersed byvarious methods. Liquid forms are easier to handle; however, they work best in shallower lakesand ponds. Rotenone is usually applied in the summer or fall when the water temperatures areabove 20'C. There are several factors that affect the toxicity of rotenone; water temperature,light, dissolved oxygen, turbidity, and alkalinity. Some species of fish can tolerate low levels ofoxygen and are therefore less susceptible to the effects of rotenone.Antimycin is an antibiotic and is the only other chemical registered as a "general" fish toxicant(Kohler and Hubert 1993). It is available only in a liquid form and is not as effective in deeperlakes. Antimycin is commonly referred to as Fintrol; however, it is not a common product foundon the market. Antimycin is most effective in lakes, ponds, and streams that are comprised of asoft-water chemistry.n.10ý 0 1 -i stuý, M -02op vsuau 13jay IKRIBiological methods used to control undesirable fish species include the use of predation byother species of fish, birds, mammals, etc. It also includes the use of pathogens andbiomanipulation to achieve the desired ecological balance. The use of biological methodsusually requires adding one or more biological mechanism(s) into the natural system. Addingnew species or managing for a particular species to control an undesirable species can haveadverse effects on the overall management goals. Before choosing this approach, fisheriesmanagers must evaluate whether the predator-prey combination will be effective as a controlagent. Biological control methods are less expensive than chemical methods; however, thedesired result is not attained as rapidly as with chemical methods, but often it is a morepermanent method.Mechanical methods used to control undesirable fish species include water level manipulation,traps, barriers, commercial fishing, and electricity. Other methods include seines, trawls, gillnets, and cast nets. All of these gears are labor intensive and require multiple applications overan extended period of time to have an overall impact on the fishery.Complete eradication of undesirable fish species is seldom possible. However, control of existingspecies can be achieved by using methods that are applied at a time and location when theundesirable species is most vulnerable. The use of an integrated management approach mayprove to be more effective than any one single approach.Based on the fish species present and the present population structure, management of thesespecies may be best achieved by utilizing a combination of management approaches. Somepossible approaches could include the following:* Complete removal of both species through the use of chemicals such as Rotenone;* Management of species using both mechanical and chemical methods such as trawls,seining, and traps, followed by supplemental Rotenone applications;* Management of species using mechanical methods described and supplemented by stockingof predator species; and* Management of species using only mechanical methods.U3,C-~AOOrcurisi rpuiwuiiowuyIV~Y CUC 15U 7-00/-JIoI Po'pulation Study14auy -'u All things considered, total removal of all fish from the Essential Cooling Pond may not bepossible and or desirable due to beneficial aspects such as algae control. Using chemicals canbe quite costly and will most likely not kill all the fish in the pond. Remaining individuals would beable to repopulate the pond in time. Furthermore, a massive kill could require a considerableamount of manpower and there is the possibility that dead fish would clog the screens at theintake structure.Managing the species using multiple methods may prove most beneficial. First, capture of the fishusing trawls or other gear will provide continuing data on the productivity of the fish population.Second, the cost associated with sampling will not be as high. Third, sampling could take placeduring times of the year when fish populations are the highest and pose the greatest threat to thepumps. For example, changes in numbers or species distribution detected in minnow traps couldbe used to implement control methodology. Fourth, supplementing the sampling with heavydosages of rotenone in specific areas of the lake during peak spawning periods and before orduring the coldest winter months could help manage the populations. An additional approachincludes managing the pond by having a commercial fisherman harvest the two fish species.Both species are popular on the tropical fish market and/or are used by commercial laboratoriesfor toxicity testing.The use of biological methods does work in some well managed lakes and ponds. However, theuse of a biological control in the ECP would require continued management of stocked predatorspecies and could eventually become a management problem in and of itself in the future.Given the dynamics of the ECP and the species present, managing the fish population will requirean established monitoring and control plan based on the recommendations above. Periodicmonitoring of the fish population in the pond should be used to determine if any controlmethodology is required based on plant operational considerations. For example, quarterlysampling using minnow traps with a standardized sampling program would provide size andspecies distribution information that could serve as a basis for initiating additional actions.Jug C, tJv0,c, r~~orICI H FUWUHGIIUI H CtUU~Uol~ ~ ~~ op a, lliFVInU Ituy15ay S:~RIn an effort to prevent impingement after extended periods when a pump may be shut down, it isrecommended that chemicals could be applied to the screen/pump wells prior to shut down toexclude or eliminate fish. Additionally, the placement of stop logs in the intake structure shouldhelp to preclude fish from utilizing the screen/pump wells during the down periods. ~n~t ,~ -jQ.r11. o- -i Q ..1.116tivay II1IcR.4.0 LITERATURE CITEDAlder, H.

Dear Mr. Gangluff:
I received your letter dated May 24, 2007, requesting that the Main Cooling Reservoir (MCR) bedesignated as a closed-cycle recirculating system and as not water in the state.The Texas Commission on Environmental Quality (TCEQ) does not have an official method of"designating" a facility's operation as a closed-cycle recirculating system. However, we have reviewedthe information you submitted and based on our best professional judgement, we consider your facility tobe a closed-cycle recirculating system. As mentioned in your letter, the federal rule governing the 316(b)Phase I1 cooling water intakes is currently in the process of being suspended. For the time being,implementation of the 316(b) requirements will be based on best professional judgement (BPJ) andsubject to EPA Region VI review.We also concur that the Main Cooling Reservoir (MCR) at your facility does not meet the definition ofwater in the state.If you have any questions, please contact me at (512) 239-2369.Sincerely,Kelly Ilolligan, LeaderIndustrial TeamWater Quality DivisionKH!jpP.O.

The operational studies involve a continuationof procedures established during construction phase monitoring,which covered the period 1978-1987.Species selected for monitoring were considered to beindicators of general environmental quality. Both Americanalligators (Alligator mississippiensis) and bald eagles(Haliaeetus leucocephalus) were originally chosen because oftheir endangered and threatened species status. Since the studywas initiated the status of the American alligator in Texas hasbeen changed from endangered to threatened by similarity ofappearance (Federal Register 1983). Other species selected formonitoring were white-tailed deer (Odocoileus virginianus) andwaterfowl (family Anatidae) because of their recreational andeconomic importance to the region. Selected resident waterfowland shorebirds were also monitored for changes in populations.Presented in this report are the results of fieldinvestigations conducted on and near the STP site betweenSeptember 1987 and May 1988. These data are summarized andcompared with data obtained in earlier years (1978-1987). Theresults of studies conducted in previous years were reported bySpringer (1980), Leavens et al. (1981), Davis (1952, 1983), Davisand Wilkinson (1984), Greene et al. (1985), Baker et al. (1986),Greene et al. (1987), and Baker and Greene (1988).STUDY AREAThe STP site is located in southern Matagorda County,approximately 16 km south of Bay City, on the west bank of theColorado River (Figure 1). Over half of the 5000 ha site isoccupied by a cooling reservoir which presently has an averagedepth of about 3.5 m.Vegetationally, the study area is part of the Gulf Prariesand Marshes region (Gould 1975). Five basic wildlife habitatshave been identified on the site: (1) the disturbed constructionarea, (2) the cooling reservoir, (3) the woodlands between thereservoir and the Colorado River, (4) drainage and irrigationcanals, and (5) Kelly Lake.1 I ý'OKLAHOMAI68ýww M0,00Art0tRa~EIC OrtF -& 1 tWGULF O0FMEXICOFIGURE 1. Location of the South Texas Project site METHODSAlligator SurveyAlligators at the STP site were surveyed along previouslyestablished transects. Figure 2 shows transect locations andlengths. Transects 1 and 5 (Kelly Lake and Relocated LittleRobbins Slough) were surveyed on 3 consecutive nights. Transect10 was surveyed on three consecutive days. The night surveyswere conducted no earlier than 1 hour after sunset and no laterthan 30 minutes before sunrise. All surveys were conducted on17-19 May 1988 during the dark phase of the moon (new moon).Surveys have been conducted during the dark phase of the moonsince the monitoring study began to ensure high count accuracyand to standardize the procedures (Chabreck 1966). Surveys wereconducted in May, the peak of the breeding season, whenalligators of both sexes travel a great deal and are moreconspicuous than at other times of the year (Joanen and McNease1975, Nichols et al. 1976).Transect 1 was surveyed by canoe, the other two by truck. A400,000 candlepower spotlight was used to locate the alligatorsat night. Their eyes reflect a characteristic amber glow thatcan be easily recognized and detected from several hundred yards(Chabreck 1966). With a light shining in their eyes, mostalligators will remain stationary long enough to be approachedwithin range for reliable size estimation. The alligators wereeasily approachable by truck during the day as well. Intransects 1 and 5 the alligators were assigned to size classes byestimating the distance from their eyes to the tip of theirsnout. The total body length was estimated using the formula:x = -0.5113 + 1.1456ywhere x is total length in feet and y is snout length in inches.This formula was derived by linear regression from data reportedfor coastal Louisiana alligators (Chabreck 1966). Alligatorsgreater than 1.8 m (6 ft) in length were considered adults(Nichols et al. 1976). On transect 10 (the Entire Dike), lengthestimates were made from observations of the entire animal whenvisible or from snout length when the entire animal was notvisible. The highest count for each survey period was used asthe minimum population estimate for that period.White-tailed Deer SurveyWhite-tailed deer surveys were conducted on five consecutivedays during the week of September 27-October 2, and during thefirst full week of November and December.3

Deer were observed from two fixed observation points and adriving transect between these two points. The two fixed pointswere located on the dike adjacent to the makeup right-of-way andthe blowdown canal (Figure 3). Observers watched the fixedsurvey areas for 30 minutes starting at sunrise and 30 minutesprior to sunset. Observation times for a site were rotated onalternate days, e.g., if the blowdown canal was surveyed in themorning on the first day, it would be surveyed in the evening onthe second day. The driving transect was along the western edgeof the woodlands adjacent to the reservoir. It was surveyed inthe morning and evening of each day by driving along the dikeafter each fixed survey, stopping to count and identify deer asnecessary. A 22X spotting scope was used to help classify deeraccording to age and sex. Incidental deer observations were alsorecorded while conducting waterfowl surveys.Waterfowl SurveysDucks, geese and other waterfowl are most abundant on theSTP cooling reservoir during the fall and winter months.Population estimates were made on five consecutive days duringthe week of September 27-October 2, and the first full week ofNovember and December. Observations began after the dawn deersurvey and ended before the dusk deer survey. Species wereidentified with the aid of a 22X spotting scope. The highestdaily count of each species in each month was used as the minimumpopulation estimate of that species.Additional data were obtained from the annual aerial surveysof duck and goose populations wintering in Texas, which werecoordinated by the U.S. Fish and Wildlife Service (USFWS) andconducted by the Texas Parks & Wildlife Department (TPWD). Forsurvey purposes, Texas is currently divided into five waterfowlzones by TPWD: Northeast Texas, Northwest Texas, North-centralTexas, Lower Coast and Upper Coast. Matagorda County is in theUpper Coast zone. Total goose estimates were derived fromcombined totals of Texas Coastal Goose Inventory Zones 1-3. Ducktotals were derived by combining totals in Texas Mid-winterWaterfowl Inventory Zones A,B,C, and D.Bald Eagle SurveyAll large raptors are carefully observed during waterfowlsurveys to see if they are bald eagles. In addition, reports ofbald eagle sightings in the vicinity of the STP site weresolicited from specified site personnel.5 F.'.oSITEBOUNDARYINt'COOLING RESERVOIRRESERVOIR DIKE* *OBSERVATION POINTS........ ! TRANSECT LINEWhite-tailed deer observation points and transect line on the east side ofthe STP cooling reservoir.406 An extensive aerial search for bald eagle nests in easternand coastal Texas was conducted by TPWD personnel in January,February and early March of 1988. Nests found to be active wereexamined again in March and later to determine the number ofyoung produced (Mabie 1988). When new eagle nests were located,TPWD biologists contacted landowners to acquire nest historydata.7 RESULTS AND DISCUSSIONAlligator SurveyThe maximum number of alligators observed on transects atthe STP site in 1988 was 53 (Table 1). The highest mean densityof alligators seen was 7.0 alligators/km on the Kelly Laketransect (Table 2). This represents a reduction in the densityof alligators from the 1987 census, which was apparent in all 3observation transects (Table 3). The total number of alligatorson the site continues to decline, but should begin to stabilizenow that the plant is operational, although seasonal variationsin population level will probably remain.Results of the Entire Dike survey in the Spring of 1988showed a total of 23 alligators. This represents a reduction of27 animals from the 1987 Fall survey, 7 from the 1987 Springsurvey, and 58 from the 1986 Spring survey (Table 4). Thisdecline was predicted to occur as reservoir fill operationsinundated nesting habitat in the Main Cooling Reservoir (MCR)(Baker and Greene 1988). Now that the water level is atoperational design levels the population of alligators in the MCRshould remain relatively constant, being dominated by adultmales. Based on total length estimates, the 1988 Spring surveyof the MCR showed a 98% adult population present.Results of the Kelly Lake transect indicate a maximum numberof 27 alligators. This is slightly lower than the Spring 1987survey of 32. The 1988 density in Kelly Lake was 7.0alligators/km which is well above densities recorded from1978-1985, but slightly below the density of 8.3 alligators/kmrecorded in 1987. The 1988 Kelly Lake population consisted of69% adults and 31% juveniles. Kelly Lake remains as the primealligator nesting habitat site at the STP.The Relocated Little Robbins Slough transect had a maximumcount of 3 alligators in the Spring 1988 survey, down about 50%from 1986 and 1987. This decline can probably be attributed to amajor construction project which involved dredging the entiretransect channel and resurfacing it with a layer of sand, matmaterial, and irregular shaped stone. The renovation of theSlough was completed in early 1988, just prior to the survey.Subsequent to these activities, the alligator population in theLittle Robbins Slough should stabilize. All alligators observedon this transect in 1988 Spring survey were juveniles.White-tailed Deer SurveyIn 1987 the greatest number of deer observed per day was 29,which occurred in the October survey (Table 5).

Before the largest numbers werechosen, Unknowns were apportioned to Bucks, Does and Yearlingsin the percentage in which they occur in the population.13 survey showed a significant drop in deer totals in the Woodlands Aldrive transect and the Blowdown transect (Table 6). This declinewas probably due to intense construction activities on the upperhalf of the Blowdown transect and the associated traffic movingalong the Woodlands drive transect. Worker shift changes closelycoincided with the morning and evening drive transect schedules.This trend continued on the drive transect in December, butcounts increased on the Blowdown transect as heavy equipment workdeclined. Following these construction activities, deer totalsshould return to levels observed in the three previous annualsurveys.Approximately 63% of the deer sighted in all survey areaswere adult does (Appendix Tables I-IV). Bucks comprisedapproximately 17%, yearlings 19%, and unknowns 1% of thepopulation. These figures compare favorably to previous STP deersurveys. Downing et al. (1977) pointed out the inherent bias andthe unequal observability between sex and age classes ofwhite-tailed deer, so it is doubtful that these data representthe true proportion of sex and age classes.Only 2 deer were observed during the waterfowl survey at theMain Cooling Reservoir (Appendix Table IV). Both were does,observed during the October survey.Waterfowl SurveyThe total number of ducks observed in the 1987 maintained Aethe population decline that began in 1985. Species diversity alsocontinued to decline with only 16 duck species observed in thethree month survey of the Main Cooling Reservoir (Table 7). Inthe 1987 survey 84 ducks were observed in October, 1,768 inNovember, and 665 in December (Table 7). The most abundant duckin October was the Black-bellied whistling duck. In Novemberand December the most abundant duck was the Lesser scaup. Itshould be noted that other wetland habitats on site such as KellyLake and the Little Robbins Slough, along with numerousdrainages, continue to have high species diversity.The highest number of total geese was recorded in December.Snow geese were the most abundant species with 1,656 individualsobserved, followed by Canadian geese at 309, and theWhite-fronted goose at 130. Goose counts were significantlylower in 1987 than in any of the 5 previous years.As mentioned previously (Baker and Greene 1988), reservoirfill operations have inundated the temporary marshes and isolatedislands within the Main Cooling Reservoir, and have created adeep, open-water habitat. This change in habitat due toreservoir filling is the main reason for the decline in speciesdiversity and total numbers of waterfowl on the MCR. Aspredicted (STP ER-OL 1985), the dominant duck species on the MCRare now diving ducks (e.g. Lesser scaup and Ring-necked ducks)(Table 7).014 TABLE 6.

The Cormorant spp. was the most abundant species (287 seenin December), followed by the Anhinga (169 in October) and theGreat blue heron (111 in October).In general, species which require shallow water habitat,aquatic vegetation, and woody vegetation have declined inabundance since 1984 (Table 8). Examples of this are the Commongallinule, Purple gallinule, American coot and Pied-billed grebe.Waterfowl species which thrive in open water and non-vegetatedshorelines have maintained or increased their population numberssince 1983. Examples are the Great blue heron and Cormorant spp.This shift in populations can be attributed to the rise of thewater level within the reservoir. This trend will probablystabilize now that operational levels have been reached.Biologists from the Texas Parks and Wildlife Departmentannually survey set transects to assess the duck and goosepopulations in Texas. The goose survey was conducted during theperiod December 14-17, 1987, and the duck survey during theperiod January 11-13, 1988 (Lobpries 1988).Total geese for the 1987-88 survey was 700,300 (Table 9).This represents the lowest total in the six year period reported.The decline is in all three species of geese. The Snow goose andWhite-fronted goose totals represent an all time low in thesurvey of 584,200 and 65,000 respectively. Only in the 1982-83survey was the Canada goose total lower than the 51,100 reportedin the 1987-88 survey.Total ducks for the 1987-88 survey was 1,644,200 (Table 9).This total is significantly higher than the 1986-87 total of972,400, and is the highest total recorded in the last six yearsof the survey. Northern pintails and Green-winged teal were atpeak levels, accounting for almost 80% of the total duck survey.Bald Eagle SurveyA reliable source reported the sighting of one mature baldeagle on the STP site near the blowdown canal (Fig. 2) in April1988. This was the only observation of a bald eagle on the sitein 1988.During January, February and March 1988, the Texas Parks andWildlife Department conducted its annual bald eagle nest survey(Mabie 1988). Of 20 active nests in Texas, 16 were found in areaC, the counties surrounding the STP site (Figure 4). Ten of the16 active nests fledged 15 young.

Number of known active bald eagle nests in TPWD survey area C, 1987(Mabie, 1987).20 SUMMARYPopulation levels of alligators, white-tailed deer, waterfowl and baldeagles were monitored on the STP site to detect any changes that might beattributed to operational activities. Field studies were conducted betweenlate September 1987 and May 1988.The alligator population on the STP site continues to decline. Only53 alligators were counted in 1988, compared to 69 in 1987, and 94 in 1986.It appears that the main cause for the decline is the elimination ofsuitable habitat within the main cooling reservoir. The population shouldbegin to stabilize now that water has reached operational levels in themain cooling reservoir.A maximum of 29 deer were seen in 1987. The deer population wasrelatively stable during the previous 3 survey periods, but constructionactivities on the Blowdown transect during the 1987 survey resulted in aslight population decline. When construction activity is completed thedeer population should stabilize at previous levels. Adult does accountedfor 63% of the deer population, bucks 17%, yearlings 19% and unknown 1%.In the 1987 survey, 84 ducks were observed in October, 1,768 inNovember, and 665 in December. The most abundant duck in October was theBlack-bellied whistling duck. In November and December the most abundantduck was the Lesser scaup. Total numbers of ducks and species diversityhave declined since their peak in 1984.Geese were most abundant in the month of December. Snow geese werethe most abundant species with 1,656 individuals observed. Goose counts onthe site were at their lowest levels since 1981, which corresponds to TPWDcounts in Texas Coastal Zones.Of the 23 species of waterfowl other than ducks and geese, theCormorant spp. was the most abundant species (287 seen in December),followed by the Anhinga (169 in October) and the Great blue heron (111 inOctober).Reservoir fill operations in late summer and early fall of 1985inundated prime waterfowl habitat. This appears to be the major factor forthe recent decline in waterfowl population numbers and species diversity.As the lake level has risen, there has been a decline in the numbers ofdabbling ducks (e.g. Galdwall, Northern pintail and American wigeon) and anincrease in the number of diving ducks (e.g. Lesser scaup and Ring-neckedducks). Populations should begin to stabilize now that the reservoir waterlevel is at the operation design level.One bald eagle was observed on the STP site in 1987. In countiessurrounding the STP site, the Texas Parks and Wildlife Department recorded16 active nests. The total number of fledgling eagles was 15, which wasslightly lower than the 18 fledged in 1987.21 LITERATURE CITEDAmerican Ornithologists' Union. 1983.

It is recommendedthat hunting of each management unit be restricted to no morethan three (3) mornings per week.The Cooperator shall provide and/or perform the followingimprovement related wildlife habitat development activities:Units 1, 2, & 3 collectively comprise 110 acres of farmland thathas been taken out of agricultural production. The units will bedeveloped and managed to provide seasonal/semi-permanent wetlandhabitat for wintering migratory waterfowl, and other wetlanddependent wildlife.The units will be managed for the production of native moist soilvegetation, with a water depth averaging from 6"-18". Floodingof the impoundments should begin with the installation of someflash boards by August 15 or as soon as moist soil plants havebecome well established. All flashboards should be installed upto the designed maximum water level by November 1. TheCooperator agrees to "guarantee" 55 acres of surface water (bypumping or purchase from irrigation canal) if runoff conditionshave not provided same by November 1 of each year.The impoundments should remain flooded until at least March 1each year to provide habitat for waterfowl during the springmigration. A slow annual drawdown (over a 2-4 week period) atthis time will allow revegetation of valuable seed producingannual moist soil plants. If inundation of the impoundments doesnot interfere with spring/summer land use operations, annualdrawdown could be postponed as late as June 1. Late seasondrawdowns should be staggered and rotated annually for all unitsbetween the months of May and June. This type of late seasondrawdown will provide valuable brooding habitat for nestingmottled ducks and whistling ducks, encourage plant/habitatdiversity, and reduce mowing expenses.In some years (every 3-4), it may be necessary to lightly disc,shred, or burn the impoundment if undesirable plants (eg. senabean, and cattail) become dominant. This soil disturbance willset back plant succession and encourage the production of moredesirable waterfowl foods. All flashboards should be installedafter these moist soil plants have germinated and become firmlyestablished (typically by November 1).10 If vegetation within the project site is overly dense, it may benecessary to create several open areas by shredding, rolling, orlightly discing the vegetation. This will provide open waterareas to allow waterfowl access into the impoundments. However,if waterfowl will be hunted on the sites it is advised to consultcurrent federal "baiting" regulations for compliance before thehabitat is mechanically manipulated.Undesirable woody vegetation and rank wetland plants such ascattails should be controlled throughout the site. Mowing ofwoody vegetation on levees and within the impoundments shouldprevent more difficult control problems with larger trees andshrubs in the future.Impoundments with newly constructed levees should not be filledto capacity immediately following completion. The-slopes ofthese levees need to settle and vegetate to resist shorelineerosion. At no time should impoundments be held above designcapacity which provides at least 12" of freeboard to the tops oflevees.The Project Initiator and/or other Texas Prairie Wetland Projectrepresentatives shall periodically provide technical assistancefor the beneficial management of the wetland habitat developedunder this agreement.

The proposedProject is located at the South Texas Project Electric Generating Station (STPEGS) in Matagorda County,Texas, Figure 1. The scope of work included conducting an analysis of current and historic mapping andbiological data using Geographic Information System (GIS) data sets and data collected during onsite wetlanddelineations surveys, threatened and endangered species surveys, and routine site visits. In addition to thehabitat assessment, this report provides a summary of bird species and relative important species (RIS)associated with the documented habitats within the STPEGS property. Data in this report will be used tosupplement information in the Environmental Report for the COL application.1.1 Project and Site DescriptionSTPNOC is currently proposing to license, construct, and operate two additional generating units (Units 3 and4) at its STPEGS facility located on FM 521 approximately 8 miles west of Wadsworth, Texas. The STPEGSproperty currently consists of approximately 12,220 acres of land located adjacent to the Colorado River,Figure 1. The geographical and ecological region associated with the facility is referred to as the coastalplains, which historically was comprised of tall grass prairies, open grasslands, and bottomland habitat areasnear creeks and rivers. The current setting and habitat of the region consists almost entirely of agriculturalfarmland, pastureland, and bottomlands. The plant property is currently occupied by approximately 7,346acres of existing plant facilities which include an approximate 7,000-acre Main Cooling Reservoir (MCR), 300acres for the existing Units 1 and 2 and associated buildings and warehouses, and 46 acres for the EssentialCooling Pond. The remaining property (approximately 4,874 acres) is comprised of undeveloped lands thatinclude bottomland habitat, leased agriculture/pastureland, managed wetlands, scrub shrub and mix habitats.A detailed description of habitat areas is provided in Section 3 of this report.The proposed construction of Units 3 and 4 will require the additional use of approximately 244 acres of land.Figure 2 provides an overview of the proposed project layout for each of the following components. Thecurrent project scope includes the following construction and operating activities for Units 3 and 4:* Construction and operation of Units 3 and 4;* Construction of a new switchyard;* Clearing and maintenance of additional storage and materials laydown yards;* Clearing and maintenance of a new heavy haul road;* Construction of a radioactive waste storage building;* Relocation and construction of the existing drainage ditch;* Construction of a concrete batch plant;* Clearing and maintenance of materials spoil area;* Construction of a new Cooling Water Intake Structure (CWIS) and discharge system; and* Clearing and maintenance of additional contractor and craft parking areas for the construction of Units3 and 4.Habitat Report Document 1-1 June 2008 2.0 MethodsThe following section describes methods implemented by ENSR's biologists for completing the habitatassessment and summarization of bird species and relatively important species (RIS) at STPEGS. Data inthis report were compiled using available GIS data, data collected during onsite wetland delineations,threatened and endangered species surveys, Christmas Bird Counts, and routine site visits from 2006 through2008. GIS data sets were compiled using available data from the following sources:" U.S. Geological Survey (USGS) 7.5-minute Topographic Quadrangle Maps;* U.S. Fish and Wildlife Service (USFWS) National Wetlands Inventory (NWI) Maps;" Aerial Photographs (1974 and 2004);* Natural Resources Conservation Service (NRCS) Soil Surveys for Matagorda County, Texas; and* Texas General Land Office (GLO) Land Use Classification Data.GIS data were then incorporated into ArcGIS programs to create a geo-referenced base map for the property,Acreages were calculated by assigning GIS polygons to each of the different habitats by interpreting changesin vegetation and land use. These calculations are considered approximations or estimates of the acreagebased on aerial coverage of each polygon. Identified features in the GIS data set were then field verifiedduring routine site visits to document actual habitat types.Field surveys were conducted in conjunction with the wetland delineations and threatened and endangeredspecies surveys which occurred in December 2006, February 2007, and April 2008. Pedestrian surveys wereperformed by walking transects spaced 200 ft apart in areas where vegetative cover had distinct changes and500 feet apart in areas where vegetation remained similar. Data from these surveys were compiled intoindividual reports and submitted to the Habitat Assessment Branch of the Texas Parks and WildlifeDepartment (TPWD) in March 2007 and then to the TPWD Resource Protection and U.S. Fish and WildlifeService in December of 2007 (ENSR 2007). Habitats documented during these surveys were used to developa habitat map for the STPNOC property, Figure 3. Upon completion of the habitat map, areas were furthersurveyed by ENSR, NRG biologists, and a biologist from the Natural Resource Conservation Service (NRCS)to verify vegetative communities within the construction areas of the project.Data from the STP Section of the Audubon Society Mad Island Christmas Bird Counts, 1993-2007, were usedfor the bird evaluation. Data were summarized on an annual basis to determine yearly trends in speciesrichness and relative abundance. Bird counts at the STPEGS facility were collected from multiple locationsassociated with each of the different habitats. Documented species were grouped based on their knownhabitat assemblages and then categorized according to those habitats documented at STPEGS to identify keyareas associated with the project.A qualitative assessment of wildlife species at the STPEGS facility was completed by documenting wildlifespecies during multiple field activities conducted from 2006 to 2007(ENSR 2007). Emphasis was placed ondocumenting relative important species and their known habitats. Relative important species include thosespecies that belong to any of the following groups:* Those species listed as state or federal threatened and endangered species;* Species proposed for listing as a threatened and endangered or is a candidate for listing;* Commercially or recreationally valuable species;" Species that are critical to the structure and function of local terrestrial ecosystems; andHabitat Report Document2-1June 2008
- Species that may serve as biological indicators to monitor the effects of the proposed facilities on theterrestrial environment.During the initial licensing phase for Units 1 and 2 (1974-1987) species considered as "important" included thewhitetail deer, American alligator, bald eagle, and all waterfowl.Habitat Report Document/-4June 2008 3.0 ResultsThe results of the habitat assessment for the proposed Unit 3 and 4 licensing project are presented in thefollowing sections. Descriptions of habitat types and vegetation communities are discussed. Table 1 providesa summary of the habitat types, vegetation communities, and acreages for each identified community withinthe STPEGS facility and provides an overview of the habitats that will potentially be impacted by the project.3.1 Habitat DescriptionsFourteen habitats types were documented within the STPEGS property. Figure 3 illustrates the locations ofeach of the identified habitats and provides a summary of the potential habitat impacts. The documentedhabitat types include:1. Main Cooling Reservoir (MCR);2. Bottomland;3. Scrub Shrub;4. Maintained and disturbed areas;5. Forested communities;6. Forested/mixed pastureland/leased land;7. Mixed grass communities;8. Wetlands;9. Existing facilities;10. Unit 1 & 2 construction spoil area;11. Essential Cooling Pond (ECP);12. Reservoir levee system;13. Dredge materials disposal area; and14. Leased agricultural land.Main Cooling Reservoir and Essential Cooling PondThe MCR is an approximately 7,000-acre reservoir originally designed to provide closed cycle cooling for fourgenerating units. Make-up water for the reservoir is pumped from the Reservoir Make-up Pumping Facility(RMPF) approximately 1 mile from the Colorado River to the MCR. The MCR is a perched system constructedof earthen levees covered by grasses on the outside slopes and sandcrete on the inside slopes. There are aseries of levees inside the MCR which lengthen the flow path, providing extended circulation and cooling of thewater. The MCR is designed to handle a capacity of 49 ft MSL; however, it is currently maintained at a waterlevel .of 47 ft MSL. Water depth in the MCR averages 25 ft with the exception of a few deep holes that reach35 ft. These deep holes are associated with soil borrow areas used in the construction of the levees. Salinityin the reservoir remains constant at approximately 1.6 ppt. Fishery studies conducted on the MCR indicatethat both freshwater species and saltwater species are present (ENSR MS). There is little to no natural habitatwithin the MCR and any areas considered habitat are confined to the steep levee shorelines and the areasassociated with the cooling water intake structure.Habitat Report Document3-1June 2008 The Essential Cooling Pond (ECP) is a 46-acre perched pond designed to supply water to cool crucial plantcomponents. The pond is constructed of earthen levees covered by grasses on the outside slopes andsandcrete on the inside slopes providing a hard substrate surface. The ECP is considered openwater habitatand contains no natural structure. A fish study completed in 2002 indicated that the ECP supports a significantpopulation of sheepshead minnows, mosquito fish, and sailfin mollies. No large aquatic organisms such assunfishes or catfishes were documented.The MCR and ECP consist of both external and internal levees that are constructed of earthen materials coverby sandcrete on the inside slopes and grasses on the outside slopes. The internal levees for both areas arecovered entirely by sandcrete materials. The footprint of all the levees combined comprises approximately 759acres. The grasses on the outside of the levees consist primarily of angleton bluestem, King Ranch bluestem,dallisgrass, Bermuda grass, and perennial rye grass. These are mowed on a routine basis and provide limitedhabitat to wildlife. The shoreline around the MCR and ECP provides roosting and nesting habitat for a varietyof colonial shore birds.Bottomland and Forested HabitatsApproximately 1,176 acres of bottomland forest habitat exists along the eastern boundary of the STPEGSproperty. This habitat borders the Colorado River and is comprised of a mixture of trees, shrubs, and grasses.The dominant tree species include sugarberry/hackberry, pecan, cottonwood, water oak, live oak, Americanelm, willow, and Chinese tallow. Shrub species include yaupon, Chinese privet, McCartney Rose, andAmerican beautyberry. Grasses include woodoats, carpet grass, crab grass, broomsedge, and Bermudagrass. Vines include greenbriar, poison ivy, and southern dewberry.Three important components of the STPEGS facility are located within the bottomland area. These include theRMPF, the dredge materials disposal area, and the spillway/blowdown area. The RMPF is located in thenorthern portion of the bottomland area and occupies approximately 6 acres. The dredge materials disposalarea is a 133 acre area located just south of the RMPF. The area is used for the placement of dredgedmaterials from the RMPF and barge slip. The spillway/blowdown area consists of an approximate 1 mile long,man-made canal that is designed to provide emergency release of water from the MCR to the river.Additional forested communities are located on the east side of the property north of the heavy haul road andon the southeast section of the property between the MCR spillway and the Colorado River. The area north ofthe heavy haul road includes 53 acres of forested habitat that includes live oak, sugarberry/hackberry, andyaupon. This area surrounds Kelly Lake and extends north to FM 521. Just east of this section isapproximately 91 acres of forested/mixed pastureland habitat that is currently leased for cattle grazing. Treesin this area are comprised predominantly of sugarberry/hackberry with a few live oaks mixed throughout.Grasses in this area include Bermuda grass, carpet grass, crabgrass, smut grass, dallisgrass, and paspalumspp. The forested area near the spillway is a component of the bottomland habitat and contains similarspecies as described in the bottomland habitat.Scrub ShrubScrub shrub habitats dominate the western and northern portions of the property totaling 976 acres. The scrubshrub communities are comprised mostly of sea myrtle, goldenrod, ragweed, aster, southern dewberry,peppervine, sumpweed, and in some areas McCartney rose. Very few grass species are included in thishabitat primarily due to the dense coverage of the shrub vegetation. Grasses that are present includebroomsedge, bushy bluestem, paspalum spp., and bristle grass.Mixed GrassesApproximately 486 acres of the STPEGS property are comprised of predominantly mixed grass communities.These areas are located along the southern boundary of the MCR, north of the essential cooling pond (ECP),and two areas within the bottomland habitat. Grasses in all three areas are comprised predominately ofangleton bluestem, King Ranch bluestem, bristle grass, brownseed paspalum, vasey grass, smut grass, andBermuda grass. Part of the area north of the ECP includes several small disturbed areas with vegetation thatincludes goldenrod, aster, ragweed, and sumpweed.Habitat Report Document 3-2 June 2008 WetlandsWetland habitats located within the STPEGS property include Kelly Lake (34 acres), the managed wetlandsarea (110 acres), and delineated wetlands (11 acres). Kelly Lake is located on the northeast portion of theproperty and consists of open water areas surrounded by fringing wetland plants including cattails andarrowhead. The managed wetland area is located on the northern portion of the property along FM 521. Thisarea was developed in a partnership between STPNOC and Ducks Unlimited and various other agencies toprovide prairie wetland habitat for waterfowl and coastal wading birds. Delineated wetlands include 20 smallwetlands located in various locations around the property. Sixteen of the wetlands are less than 0.5 acres insize while the other four wetlands range from 0.63 acres up to 3.78 acres in size. None of the identifiedwetlands are associated with or have a significant nexus to waters of the U.S. Dominant wetland vegetationassociated with these wetlands includes: spikerush, cattail, water hyssop, knotgrass, bushy bluestem, seamyrtle, and rattlebox.Existing FacilitiesApproximately 300 acres of the STPEGS property is associated with the existing plant facilities for Units 1 and2. These facilities include the generating units, warehouses, storage yards, switchyard, intake structure,Nuclear Support Center (NSC) building and parking areas. Most of these areas are comprised of paved andcrushed rock surface areas that have some mixed grasses growing sporadically throughout the area. Anadditional component of the existing facilities includes the 41 acre Unit 1 and 2 construction spoil area locatedon the west side of the property. This area was used during the initial construction phase for stockpiling soils.The area is not currently being used and has established vegetative cover that includes grasses such asangleton bluestem, bushy bluestem, dallisgrass, and broomsedge. Other species present in the constructionspoil area include sea myrtle, sugarberry/hackberry, peppervine, and southern dewberry.Maintained and Disturbed AreasMaintained and disturbed habitats are associated with portions of the STPEGS that were used initially in theconstruction of Units I and 2. These areas consist of approximately 468 acres of land that are routinelymowed and the vegetation layers are kept less than 6 inches in height. Species include a dallisgrass,brownseed paspalum, carpet grass, Bermuda grass, crabgrass, King Ranch bluestem, plantain, muhly grass,poa, broomsedge, bushy bluestem, angleton bluestem, sumpweed, and clover.Leased Agricultural LandApproximately 536 acres of the STPEGS property is leased out for agricultural purposes. These lands arelocated north and west of FM 521 and are routinely used for growing cotton and soybean. Periodically thelands are changed from agricultural use over to cattle grazing. Habitat within these areas will vary during theyear due to the type of crop and frequency of growth and planting. The areas will provide vegetative coverduring growing season and open field habitat during the non-growing seasons.3.2 Bird DataThe annual Audubon Society Christmas Bird Count (CBC) is a volunteer effort conducted to take a census ofbirds across the western hemisphere. The Mad Island CBC is a single day event occurring between mid-December and early January, over a 15 mile area that includes Mad Island Marsh Preserve and also includesthe STPEGS facility. CBC data for STP has been collected over a 15 year period from 1993 through 2007.Species richness during this time period has remained relatively stable averaging 122 species and rangingfrom a low of 60 species in 1993 and a high of 142 in 2006, Figure 4. The low in 1993 was followed by anincrease to a 112 species in 1994 then followed by stable trend for the remainder of the survey years. Totalnumber of birds surveyed varies significantly from year to year, Figure 5. The lowest total of birds countedwas 1,274 in 1993 and the highest number of total birds was 8,630,645 in 2003. Number of individuals perspecies also varies significantly from year to year and ranges from 0 to as many as 700,000 for species suchas the red-winged black bird and the brown-headed cowbird. Red-winged black birds and the brown-headedcowbirds comprise 47% and 46% of the overall total birds counted for the entire period, Figure 6. These twospecies also account for the greatest variation in total number of birds for each of the years counted. ForHabitat Report Document 3-3 June 2008 example, 0 brown-headed cowbirds were counted in 1999, 2000, and 2001, twelve were counted in 2002, and Wthen a significant increase was documented in 2003, when a total count of 4,300,000 was recorded. A similartrend occurred for the red-winged blackbird, where low counts were recorded in 2000 at 1,950 birds,increasing to a high of 4,300,270 birds in 2003.A total of 28 waterfowl species have been documented annually during the Mad Island CBC. Annual countsfor waterfowl are highly variable with numbers ranging from a low of 442 birds in 1998 to a high of 19,906 in2004, Figure 7. Snow geese demonstrated the greatest variability from year to for all the species documented.The Snow goose, Cackling goose, and the Greater White-fronted goose represent the dominant species for allyears counted, Figure 8.3.3 Habitat UseRelatively important species and birds species documented during the CBC were grouped based on theirknown habitat associations and observations of these species on the STPEGS property. Five habitat groupswere designated including openwater, woodland, grasslands, shoreline, and scrub shrub. Table 2 provides asummary of those species found in each of the groups. Many species will be included in more than one groupdue to the overlap in habitat use. Openwater species include waterfowl such as ducks, geese, pelicans, andcormorants. Woodland species include those that commonly occur in habitats associated with forestcommunities such as the woodpeckers, flycatchers, vireos, bluejays, and wrens. Grasslands birds includethose species that commonly occur in open grassland areas such as the bobwhite quail, dove, vultures, andmany of the hawk species. Shoreline birds include species such as plovers, sandpipers, killdeer, stilts, terns,and egrets. Scrub shrub birds include the groove-billed ani and the pyrrhuloxia. Other common species listedfrom some of the other groups and associated with the scrub shrub include: the sparrows, wrens, dove,grackle, and cowbirds. The largest numbers of species are associated with woodlands and openwaterhabitats.Relative important species evaluated during this assessment included those species previously identifiedduring the initial licensing phase as well as those species considered to be commercially or recreationallyimportant. Table 3 provides a summary of these species and their associated habitats. Species consideredrelative important species based on their threatened and endangered or listed status were addressed as partof the threatened and endangered species review and included in a separate report (ENSR 2007).0Habitat Report Document3-4June 2008 4.0 Summary and ConclusionsThis document provides the results of ENSR's desktop review and field investigation for the proposedSTPNOC licensing project located in Matagorda County, Texas. A total of fourteen habitat types comprisingapproximately 12,220 acres of land were identified and verified within the STPEGS property. The largestcomponent of habitat consists of the 7,000-acre Main Cooling Reservoir which provides aquatic habitat for avariety of freshwater and saltwater species, as well as nesting and feeding habitat for waterfowl and shorebirds. The 1,176 acres of bottomlands provides the most diverse habitat located within the plant property.This area supports a variety of wildlife including whitetail deer, wild hogs, squirrels, raccoons, song birds, andmigratory birds. The scrub shrub habitat, maintained and disturbed areas, and the construction spoil area areconsidered low quality habitats. Vegetative communities present in each of these areas are comprised mostlyof weeds or invasive species that have characteristically low food and habitat values due to their lack of seedsand fruits and thick spatial coverage. Approximately 34 acres of the MCR (including the levee system) and87.5 acres of the scrub shrub habitat will be impacted, Figure 3.The forested communities, forested/mixed pastureland, and mixed grass lands provide a moderate to highquality habitat. These areas provide suitable food and cover essential for sustaining wildlife populations. Theforested and forested/mixed pastureland areas will not be impacted by the proposed project; however,approximately 7 acres of the mixed grass communities will be impacted.Wetland communities within the STPEGS property are considered low to high quality habitats. The managedprairie wetlands and the Kelly Lake wetland are considered high quality wetlands based on the diversity ofplant species present and the quantity of bird species and other wildlife that utilize the areas. The remainingwetlands are considered to be low quality wetlands based on the lack of plant species diversity, location ofwetlands within the overall habitat setting, and lack of extensive wetland functions. In addition, these wetlandsdo not appear to support any aquatic life. One small palustrine wetland totaling 0.17 acres located near whereUnit 3 will be located will be impacted by the project. The remaining 19 wetlands will not be impacted.The Essential Cooling Pond provides low aquatic habitat value, There is no natural habitat cover in the pondand aquatic life is limited to a few species of small fish including sheepshead minnows, mosquitofish, andsailfin mollies. However, the hard substrate surrounding the pond does provide good roosting habitat forshoreline birds. No impacts to the ECP are proposed.Habitats within the existing facilities and the maintained and disturbed areas are considered low quality basedon the limited food and cover. Additionally, the daily operational activities and continued disturbances withinthese areas limits the amount of wildlife that are present. Some of the abandoned parking or storage areascovered with gravel do provide nesting habitats for bird species such as the killdeer and roosting habitats forother shore birds. Approximately 42 acres of the existing facilities and 73 acres of the maintained anddisturbed areas will be impacted during construction of Units 3 and 4.The leased agricultural lands provide a low quality habitat based on the overall use of the land. These landsare routinely altered, and depending on the type of crop, may only provide a resting area or temporary coverfor wildlife. No impacts from construction or operation of Units 3 and 4 will occur to the leased agriculturallands.Bird data from the Mad Island Christmas Bird Counts indicate that more than 140 species of birds totaling asmany as 8.6 million individuals are documented in a given year at the STPEGS facility. These birds areassociated primarily with five different habitats including openwater, woodlands, shoreline, scrub shrub, andgrasslands. The largest numbers of birds are associated with woodlands and openwater habitats. There willbe no impacts to the woodland habitat and a 29 acre impact to the openwater habitat. The impact to theopenwater habitat will be associated with the construction and operation of the new Cooling Water IntakeHabitat Report Document 4-1 June 2008 Structure for Unit 3 and 4 that will also include an approximate 5 acre loss of shoreline habitat. The remainingimpacts will be temporary disturbances associated with noise and moving equipment.Relatively important species and their associated habitats will have minimal to no impacts associated with theconstruction or operation of Units 3 and 4. Of the seven habitats being impacted only the scrub shrub, MCR,and mixed grass communities support any of the RIS. Impacts to RIS will be through habitat loss and not fromdirect impacts. It is anticipated that displacement of these species into other areas of the STPEGS facility, aswell as to adjacent properties, will occur resulting in minimal impacts to RIS.STPNOC is proposing to license, construct, and operate two new electric generating units (Units 3 and 4) atthe STPEGS facility. Construction of Units 3 and 4 and the associated plant features will impact seven of thefourteen identified types of habitats totaling approximately 244 acres. These habitats include existing facilities,maintained and disturbed areas, scrub shrub habitats, mixed grass communities, the MCR, wetlands, and thereservoir levee system (Other). All seven habitats are considered to be of low to moderate quality based ontheir value as a food source for wildlife, their dense vegetative cover prohibiting adequate space for wildlifemovement, and vegetative cover only providing suitable nesting habitat for a small variety of bird species.Based on these facts, impacts to wildlife are anticipated to be small.Habitat Report Document4-2June 2008 5.0 References5.1 Reference DocumentsConant, R. and J.T.

The following text includes these conditions andincorporates them into this permit. All definitions in Section 26.001 of the Texas Water Code and 30 TAC Chapter 305 shallapply to this permit and are incorporated by reference. Some specific definitions of words or phrases used in this permit areas follows:1. Flow Measurementsa. Annual average flow- the arithmetic average of all daily flow determinations taken within the preceding 12 consecutivecalendar months. The annual average flow determination shall consist of daily flow volume determinations made bya totalizing meter, charted on a chart recorder and limited to major domestic wastewater discharge facilities with a Imillion gallons per day or greater permitted flow.b. Daily average flow -the arithmetic average of-all determinations of the daily flow within a period of one calendarmonth. The daily average flow determination shall consist of determinations made on at least four separate days. Ifinstantaneous measurements are used to determine the daily flow, the determination shall be the arithmetic average ofall instantaneous measurements taken during that month. Daily average flow determination for intermittent dischargesshall consist of a minimum of three flow determinations on days of discharge.c. Daily maximum flow -the highest total flow for any 24-hour period in a calendar month.d. Instantaneous flow -the measured flow during the minimum time required to interpret the flow measuring device.e. 2-hour peak flow (domestic wastewater treatment plants) -the maximum flow sustained for a two-hour period duringthe period of daily discharge. The average of multiple measurements of instantaneous maximum flow within a two-hour period may be used to calculate the 2-hour peak flow.f. Maximum 2-hour peak flow (domestic wastewater treatment plants) -the highest 2-hour peak flow for any 24-hourperiod in a calender month.2. Concentration Measurementsa. Daily average concentration -the arithmetic average of all effluent samples, composite or grab as required by thispermit, within a period of one calendar month, consisting of at least four separate representative measurements.i. For domestic wastewater treatment plants -When four samples are not available in a calendar month, thearithmetic average (weighted by flow) of all values in the previous four consecutive month period consisting ofat least four measurements shall be utilized as the daily average concentration.ii. For all other wastewater treatment plants -When four samples are not available in a calender month, the arithmeticaverage (weighted by flow) of all values taken during the month shall be utilized as the daily averageconcentration.b. 7-day average concentration -the arithmetic average of all effluent samples, composite or grab as required by thispermit, within a period of one calendar week, Sunday through Saturday.c. Daily maximum concentration -the maximum concentration measured on a single day, by the sample type specifiedin the permit, within a period of one calender month.d. Daily discharge -the discharge of a pollutant measured during a calendar day or any 24-hour period that reasonablyrepresents the calendar day for purposes of sampling. For pollutants with limitations expressed in terms of mass, the"daily discharge" is calculated as the total mass of the pollutant discharged over the sampling day. For pollutants withlimitations expressed in other units of measurement, the "daily discharge" is calculated as the average measurementof the pollutant over the sampling day.The "daily discharge" determination of concentration made using a composite sample shall be the concentration of thecomposite sample. When grab samples are used, the "daily discharge" determination of concentration shall be thearithmetic average (weighted by flow value) of all samples collected during that day.e. Fecal coliform bacteria concentration -the number of colonies of fecal coliform bacteria per 100 milliliters effluent.The daily average fecal coliform bacteria concentration is a geometric mean of the values for the effluent samplescollected in a calendar month. The geometric mean shall be determined by calculating the nth root of the product ofall measurements made in a calender month, where n equals the number of measurements made; or, computed as thePage 2 Outfall Number 001EFFLUENT LIMITATIONS AND MONITORING REQUIREMENTS1.

The following text includes these conditions andincorporates them into this permit. All definitions in Section 26.001 of the Texas Water Code and 30 TAC Chapter 305 shallapply to this permit and are incorporated by reference. Some specific definitions of words or phrases used in this permit areas follows:1. Flow Measurementsa. Annual average flow -the arithmetic average of all daily flow determinations taken within the preceding 12 consecutivecalendar months. The annual average flow determination shall consist of daily flow volume determinations made bya totalizing meter, charted on a chart recorder and limited to major domestic wastewater discharge facilities with a Imillion gallons per day or greater permitted flow.b. Daily average- flow ý the arithmetic average of-all-determinations of-the-daily flow within a-period of-one-calendar -month. The daily average flow determination shall consist of determinations made on at least four separate days. Ifinstantaneous measurements are used to determine the daily flow, the determination shall be the arithmetic average ofall instantaneous measurements taken during that month. Daily average flow determination for intermittent dischargesshall consist of a minimum of three flow determinations on days of discharge.c. Daily maximum flow -the highest total flow for any 24-hour period in a calendar month.d. Instantaneous flow -the measured flow during the minimum time required to interpret the flow measuring device.e. 2-hour peak flow (domestic wastewater treatment plants) -the maximum flow sustained for a two-hour period duringthe period of daily discharge. The average of multiple measurements of instantaneous maximum flow within a two-hour period may be used to calculate the 2-hour peak flow.f. Maximum 2-hour peak flow (domestic wastewater treatment plants) -the highest 2-hour peak flow for any 24-hourperiod in a calender month-2. Concentration Measurementsa. Daily average concentration -the arithmetic average of all effluent samples, composite or grab as required by thispermit, within a period of one calendar month, consisting of at least four separate representative measurements.i. For domestic wastewater treatment plants -When four samples are not available in a calendar month, thearithmetic average (weighted by flow) of all values in the previous four consecutive month period consisting ofat least four measurements shall be utilized as the daily average concentration.ii. For all other wastewater treatment plants -When four samples are not available in a calender month, the arithmeticaverage (weighted by flow) of all values taken during the month shall be utilized as the daily averageconcentration.b. 7-day average concentration -the arithmetic average of all effluent samples, composite or grab as required by thispermit, within a period of one calendar week, Sunday through Saturday.c. Daily maximum concentration -the maximum concentration measured on a single day, by the sample type specifiedin the permit, within a period of one calender month.d. Daily discharge -the discharge of a pollutant measured during a calendar day or any 24-hour period that reasonablyrepresents the calendar day for purposes of sampling. For pollutants with limitations expressed in terms of mass, the"daily discharge" is calculated as the total mass of the pollutant discharged over the sampling day. For pollutants withlimitations expressed in other units of measurement, the "daily discharge" is calculated as the average measurementof the pollutant over the sampling day.The "daily discharge" determination of concentration made using a composite sample shall be the concentration of thecomposite sample. When grab samples are used, the "daily discharge" determination of concentration shall be thearithmetic average (weighted by flow'value) of all samples collected during that day.e. Fecal coliform bacteria concentration -the number of colonies of fecal coliform bacteria per 100 milliliters effluent.The daily average fecal coliform bacteria concentration is a geometric mean of the values for the effluent samplescollected in a calendar month. The geometric mean shall be determined by calculating the nth root of the product ofall measurements made in a calender month, where n equals the number of measurements made; or, computed as thePage 2 STP Nuclear Operating CompanyTPDES Permit No. WQOOO 1908000antilogarithm of the arithmetic mean of the logarithms of all measurements made in a calender month. For anymeasurement of fecal coliform bacteria equaling zero, a substituted value of one shall be made for input into eithercomputation method. The 7-day average for fecal coliform bacteria is the geometric mean of the values for all effluentsamples collected during a calender week.f. Daily average loading (lbs/day) -the arithmetic average of all daily discharge loading calculations during a period ofone calender month. These calculations must be made for each-day of the month that a parameter is analyzed. Thedaily discharge, in terms of mass (lbs/day), is calculated as ( Flow, MGD x Concentration, mg/I x 8.34).g. Daily maximum loading (lbs/day) -the highest daily discharge, in terms of mass (lbs/day), within a period of onecalender month.3. Sample Typea. Composite sample -For domestic wastewater, a composite sample is a sample made up of a minimum of three effluentportions collected in a continuous 24-hour period or during the period of daily discharge if less than 24 hours, andcombined in volumes proportional to flow, and collected at the intervals required by 30 TAC § 319.9 (a). For industrialwastewater, a composite sample is a sample made up of a minimum of three effluent portions collected in a continuous-24-hour-period-or-during-the-period of daily-discharge-if-less-than-24-hours,- and combined-in-volumesproportional toflow, and collected at the intervals required by 30 TAC § 319.9 (b).b. Grab sample -an individual sample collected in less than 15 minutes.4. Treatment Facility (facility) -wastewater facilities used in the conveyance, storage, treatment, recycling, reclamation and/ordisposal of domestic sewage, industrial wastes, agricultural wastes, recreational wastes, or other wastes including sludgehandling or disposal facilities under the jurisdiction of the Commission.5. The term "sewage sludge" is defined as solid, semi-solid, or liquid residue generated during the treatment of domesticsewage in 30 TAC Chapter 312. This includes the solids which have not been classified as hazardous waste separated fromwastewater by unit processes.6. Bypass -the intentional diversion of a waste stream from any portion of a treatment facility.MONITORING AND REPORTING REQUIREMENTS1.

Scope, Frequency and Methodologya. The permittee shall test the effluent for toxicity in accordance with the provisions below. Such testingwill determine if an appropriately dilute effluent sample adversely affects the survival, reproduction,or growth of the test organisms.b. The permittee shall conduct all toxicity tests utilizing the test organisms, procedures, and qualityassurance requirements specified below and in accordance with "Short-Term Methods for Estimatingthe Chronic Toxicity of Effluents and Receiving Waters to Marine and Estuarine Organisms, ThirdEdition" (EPA-821 -R-02-014), or the most recent update thereof:1) Chronic static renewal 7-day survival and growth test using the mysid shrimp (Mysidopsisbahia) (Method 1007.0 or the most recent update thereof). A minimum of eight replicates withfive organisms per replicate shall be used in the control and in each dilution. This test shall becondiimtd onc-per quarter.2) Chronic static renewal 7-day larval survival and growth test using the inland silverside(Menidia beryllina) (Method 1006.0 or the most recent update thereof). A minimum of fivereplicates with eight organisms per replicate shall be used in the control and in each dilution.This test shall be conducted once per quarter.The permittee must perform and report a valid test for each test species during the prescribed reportingperiod. An invalid test must be repeated during the same reporting period. An invalid test ishereindefined as any test failing to satisfy the test acceptability criteria, including Percent MinimumSignificant Difference (PMSD) boundary requirements, procedures, and quality assurancerequirements specified in the test methods and permit. All test results, valid or invalid, must besubmitted as described below.c. The permittee shall use five effluent dilution concentrations and a control in each toxicity test. Theseadditional effluent concentrations are 5%, 7%, 10%, 13%, and 17% effluent. The critical dilution,defined as 13% effluent, is the effluent concentration representative of the proportion of effluent inthe receiving water during critical low flow or critical mixing conditions.d. This permit may be amended to require a Whole Effluent Toxicity (WET) limit, Chemical-Specific(CS) limits, a Best Management Practice (BMP), additional toxicity testing, and/or other appropriateactions to address toxicity. The permittee may be required to conduct additional biomonitoring testsand/or a Toxicity Reduction Evaluation (TRE) if biomonitoring data indicate multiple numbers ofunconfirmed toxicity events.e. Testing Frequency Reduction1) If none of the first four consecutive quarterly tests demonstrates significant lethal or sub-lethaleffects, the permittee may submit this information in writing and, upon approval from the WaterQuality Standards Team, reduce the testing frequency to once per six months for theinvertebrate test species and once per year for the vertebrate test species.2) If one or more of the first four consecutive quarterly tests demonstrates significant sub-lethaleffects, the permittee shall continue quarterly testing for that species until four consecutivequarterly tests demonstrate no significant sub-lethal effects. At that time, the permittee mayapply for the appropriate testing frequency reduction for that species.3) If one or more of the first four consecutive quarterly tests demonstrates significant lethaleffects, the permittee shall continue quarterly testing for that species until the permit is reissued.If a testing frequency reduction had been previously granted and a subsequent test demonstratessignificant lethal effects, the permittee will resume a quarterly testing frequency for that speciesuntil the permit is reissued.Page 17 STP Nuclear Operating CompanyTPDES Permit No. WQOOO 19080002. Required Toxicity Testing Conditionsa. Test Acceptance -The permittee shall repeat any toxicity test, including the control and all effluentdilutions, which fails to meet any of the following criteria:1) a control mean survival of 80% or greater;2) a control mean dry weight of surviving mysid shrimp of 0.20 mg or greater;3) a control mean dry weight for surviving unpreserved inland silverside of 0.50 mg or greater and(0.43 mg or greater for surviving preserved inland silverside.4) a control Coefficient of Variation percent (CV%) between replicates of 40 or less in the in thegrowth and survival tests.5) a critical dilution CV% of 40 or less in the growth and survival endpoints for either growth andsurvival test. However, if statistically significant lethal or nonlethal effects are exhibited at thecritical dilution,_a CV% _greater than_40 shall not'inalidatethe-test.....6) a PMSD range of 11 -37 for mysid shrimp growth;7) a PMSD range of 11 -28 for inland silverside growth.b. Statistical Interpretation1) For the mysid shrimp and the inland silverside larval survival and growth tests, the statisticalanalyses used to determine if there is a significant difference between the control and aneffluent dilution shall be in accordance with the methods described in the "Short-Term Methodsfor-Estimating the Chronic Toxicity of Effluents and Receiving Waters to Marine and EstuarineOrganisms, Third Edition" (EPA-821-R-02-014), or the most recent update thereof.2) The permittee is responsible for reviewing test concentration-response relationships to ensurethat calculated test-results are interpreted and reported correctly. The EPA manual, "MethodGuidance and Recommendation for Whole Effluent Toxicity (WET) Testing (40 CFR Part136)" (EPA 821-13-00-004) provides guidance on determining the validity of test results.3) If significant lethality is demonstrated (that is, there is a statistically significant difference insurvival at the critical dilution when compared to the control), the conditions of testacceptability are met, and the survival of the test organisms are equal to or greater than 80% inthe critical dilution and all dilutions below that, then the permittee shall report a survival NoObserved Effect Concentration (NOEC) of not less than the critical dilution for the reportingrequirements.4) The NOEC is defined as the greatest effluent dilution at which no significant effect isdemonstrated. The Lowest Observed Effect Concentration (LOEC) is defined as the lowesteffluent dilution at which a significant effect is demonstrated. A significant effect is hereindefined as a statistically significant difference at the 95% confidence level between the survival,reproduction, or growth of the test organism(s) in a specified effluent dilution compared to thesurvival, reproduction, or growth of the test organism(s) in the control (0% effluent).5) The use of NOECs and LOECs assumes either a monotonic (continuous) concentration-response relationship or a threshold model of the concentration-response relationship. For anytest result that demonstrates a non-monotonic (non-continuous) response, the NOEC should bedetermined based on the guidance manual referenced in Item 3 above and a full report will besubmitted to the Water Quality Standards Team6) Pursuant to the responsibility assigned to the permittee in Part 2.b.2), test results thatdemonstrate a non-monotonic (non-continuous) concentration-response relationship may besubmitted, prior to the due date, for technical review. The above-referenced guidance manualwill be used when making a determination of test acceptabilityPage 18 STP Nuclear Operating CompanyTPDES Permit No. WQOOO 19080007) The Water Quality Standards Team will review test results (i.e., Table I and Table 2 forms) forconsistency with established TCEQ rules, procedures, and permit requirements.c. Dilution Water1) Dilution water used in the toxicity tests shall be the receiving water collected as close aspossible to the discharge point, but unaffected by the discharge.2) Where the receiving water proves unsatisfactory as a result ofpre-existing instream toxicity (i.e.fails to fulfill the test acceptance criteria of item 2.a.), the permittee may substitute syntheticdilution water for the receiving water in all subsequent tests provided the unacceptablereceiving water test met the following stipulations:a) a synthetic lab water control was performed (in addition to the receiving water control)which fulfilled the test acceptance requirements of item 2.a;b) the test indicating receiving water toxicity was carried out to completion (i.e., 7 days);-------.c) thepermittee-submitted all-test results-indicating-receivvmg-water-toxxicity-with-thereports--and information required in Part 3.Upon approval, the permittee may substitute other appropriate dilution water with chemical andphysical characteristics similar-to that of the receiving water.d. Samples and Composites1) The permittee shall collect a minimum of three flow-weighted 24-hour composite samples fromOutfall 001. The second and.third 24-hour composite samples will be used for the renewal ofthe dilution concentrations for each toxicity test. A 24-hour composite sample consists of aminimum of 12 effluent portions collected at equal time intervals representative of a 24-houroperating day and combined proportionally to flow, or a sample continuously collectedproportionally to flow over a 24-hour operating day.2) The permittee shall collect the 24-hour composite samples such that the samples arerepresentative of any periodic episode of chlorination, biocide usage, or other potentially toxicsubstance discharged on an intermittent basis.3) The permittee shall initiate the toxicity tests within 36 hours after collection of the last portionof the first 24-hour composite sample. The holding time for any subsequent 24-hour compositesample shall not exceed 72 hours. Samples shall be maintained at a temperature of 0-6 degreesCentigrade during collection, shipping, and storage.4) If flow from the outfall being tested ceases during the collection of effluent samples, therequirements for the minimum number of effluent samples, the minimum number of effluentportions, and the sample holding time, are waived during that sampling period. However, thepermittee must have collected an effluent composite sample volume sufficient to complete therequired toxicity tests with daily renewal of the effluent. When possible, the effluent samplesused for the toxicity tests shall be collected on separate days if the discharge occurs overmultiple days. The effluent composite sample collection duration and the static renewalprotocol associated with the abbreviated sample collection must be documented in the fullreport required in Part 3 of this Section.3. ReportingAll reports, tables, plans, summaries, and related correspondence required in any Part of this Section shallbe submitted to the attention of the Water Quality Standards Team (MC 150) of the Water Quality Division.All DMRs, including DMRs with biomonitoring data, should be sent to the Water Quality ComplianceMonitoring Team of the Enforcement Division (MC 224).a.

Persistent ToxicityThe requirements of this Part apply only when a test demonstrates a significant effect at the critical dilution.A significant effect is defined as a statistically significant difference, at the 95% confidence level, betweena specified endpoint (survival, growth, or reproduction) of the test organism in a specified effluent dilutionwhen compared to the specified endpoint of the test organism in the control. Significant lethality is definedas a statistically significant difference in survival at the critical dilution when compared to the survival of thetest organism in the control. Significant sublethality is defined as a statistically significant difference ingrowth/reproduction at the critical dilution when compared to the growth/reproduction of the test organismin the control.a. The permittee shall conduct a total of 2 additional tests (retests) for any species that demonstrates asignificant effect (lethal or sublethal) at the critical dilution. The two retests shall be conductedmonthly during the next two consecutive months. The permittee shall not substitute either of the tworetests in lieu of routine toxicity testing. All reports shall be submitted within 20 days of testcompletion. Test completion is defined as the last day of the test. The retests shall also be reportedon the DMRs as specified in Part 3.d.-b.-- --fhf- t-ets-.arge--e-rf-rned~due-to-a-demonstration-of.significant-lethality and-one-orboth-ofthe-two-retests specified in item 4.a. demonstrates significant lethality, the permittee shall initiate the TRErequirements as specified in Part 5. The provisions of item 4.a. are suspended upon completion of thetwo retests and submittal of the TRE Action Plan and Schedule defined in Part 5.If neither test demonstrates significant lethality and the permittee is testing under the reduced testingfrequency provision of Part I.e., the permittee shall return to a quarterly testing frequency. for thatspecies.c. If the two retests are performed due to a demonstration of significant sublethality, and one or. both ofthe two retests specified in item 4.a. demonstrates significant lethality, the permittee shall againperform two retests as stipulated in item 4.a.d. If the- two retests are performed due to a demonstration of significant sublethality, and both retestspass, the permittee shall continue testing at the quarterly frequency until such time that the permittee.can invoke the reduced testing frequency provision specified in Part L.e.e. Regardless of whether retesting for lethal or sublethalIeffects, or a combination of the two, no morethan one retest per month is required for a species.5. Toxicity Reduction Evaluationa. Within 45 days of the last test day of the retest that demonstrates significant lethality, the permitteeshall submit a General Outline for initiating a TRE. The outline shall include, but not be limited to,a description of project personnel, a schedule for obtaining consultants (if needed), a discussion ofinfluent and/or effluent data available for review, a sampling and analytical schedule, and a proposedTRE initiation date.b. Within 90 days of the last test day of the retest that demonstrates significant lethality, the permitteeshall submit a TRE Action Plan and Schedule for conducting a TRE. The plan shall specify theapproach and methodology to be used in performing the TRE. A Toxicity Reduction Evaluation is astep-wise investigation combining toxicity testing with physical and chemical analysis to determineactions necessary to eliminate or reduce effluent toxicity to a level not effecting significant lethalityat the critical dilution. The TRE Action Plan shall lead to the successful elimination of significantlethal effects at the critical dilution for both test species defined in item I.b. As a minimum, the TREAction Plan shall include the following:I) Specific Activities -The TRE Action Plan shall specify the approach the permittee intends toutilize in conducting the TRE, including toxicity characterizations, identifications,confirmations, source evaluations, treatability studies, and/or alternative approaches. Whenconducting characterization analyses, the permittee shall perform multiple characterizations andfollow the procedures specified in the document entitled, "Toxicity Identification Evaluation:Characterization of Chronically Toxic Effluent, Phase I" (EPA/600/6-91/005F), or alternateprocedures. The permittee shall perform multiple identifications and follow the methodsPage 21 STP Nuclear Operating CompanyTPDES Permit No. WQOO0 1908000specified in the documents entitled, "Methods for Aquatic Toxicity Identification Evaluations,Phase II Toxicity Identification Procedures for Samples Exhibiting Acute and ChronicToxicity" (EPA/600/R-92/080) and "Methods for Aquatic Toxicity Identification Evaluations,Phase Ill Toxicity Confirmation Procedures for Samples Exhibiting Acute and ChronicToxicity" (EPA/600/R-92/08 1). All characterization, identification, and confirmation tests shallbe conducted in an orderly and logical progression;2) Sampling Plan -The TRE Action Plan should describe sampling locations, methods, holdingtimes, chain of custody, and preservation techniques. The effluent sample volume collected forall tests shall be adequate to perform the toxicity characterization/ identification! confirmationprocedures, and chemical-specific analyses when the toxicity tests show significant lethality.Where the permittee has identified or suspects specific pollutant(s) and/or source(s) of effluenttoxicity, the permittee shall conduct, concurrent with toxicity testing, chemical-specificanalyses for the identified and/or suspected pollutant(s) and/or source(s) of effluent toxicity;3) Quality Assurance Plan -The TRE Action Plan should address record keeping and dataevaluation, calibration and standardization, baseline tests, system blanks, controls, duplicates,--..----. spikes,-tox-icity-_persistenceein-:the:samplesrandomization; referencetoxicatt -cntrol ha-tsaswell as.mechanisms to detect artifactual toxicity; and4) Project Organization -The TRE Action Plan should describe the project staff, project manager,consulting engineering services (where applicable), consulting analytical and toxicologicalservices, etc.c. Within 30 days of submittal of the TRE Action Plan and Schedule, the permittee shall implement theTRE with due diligence.d. 'Te permittee shall submit quarterly TRE Activities Reports concerning the progress of the TRE. Thequarterly reports are due on or before April 20th, July 20th, October 20th, and January 20th. The reportshall detail information regarding the TRE activities including:1) results and interpretation of any chemical-specific analyses for the identified and/or suspectedpollutant(s) performed during the quarter;2) results and interpretation of any characterization, identification, and confirmation testsperformed during the quarter;3) any data and/or substantiating documentation which identifies the pollutant(s) and/or source(s)of effluent toxicity;4) results of any studies/evaluations concerning the treatability of the facility's effluent toxicity;5) any data which identifies effluent toxicity control mechanisms that will reduce effluent toxicityto the level necessary to meet no significant lethality at the critical dilution; and6) any changes to the initial TRE Plan and Schedule that are believed necessary as a result of theTRE findings.Copies of the TRE Activities Report shall also be submitted to the U.S. EPA Region 6 office.e. During the TRE, the permittee shall perform, at a minimum, quarterly testing using the more sensitivespecies; testing for the less sensitive species shall continiue at the frequency specified in Part 1 .b.f. If the effluent ceases to effect significant lethality (herein as defined below) the permittee may endthe TRE. A "cessation of lethality" is defined as no significant lethality for a period of 12 consecutivemonths with at least monthly testing. At the end of the 12 months, the permittee shall submit astatement of intent to cease the TRE and may then resume the testing frequency specified in Part 1 .b.The permittee may only apply the "cessation of lethality" provision once.This provision accommodate situations where operational errors and upsets, spills, or sampling errorstriggered the TRE, in contrast to a situation where a single toxicant or group of toxicants causePage 22 STP Nuclear Operating CompanyTPDES Permit No. WQOOO 1908000lethality. This provision does not apply as a result of corrective actions taken by the permittee."Corrective actions" are herein defined as proactive efforts which eliminate or reduce effluent toxicity.These include, but are not limited to, source reduction or elimination, improved housekeeping, changesin chemical usage, and modifications of influent streams and/or effluent treatment.The permittee may only apply this cessation of lethality provision once. If the effluent againdemonstrates significant lethality to the same species, the permit will be amended to add a WET limitwith a compliance period, if appropriate. However, prior to the effective date of the WET limit, thepermittee may apply for a permit amendment removing and replacing the WET limit with an alternatetoxicity control measure by identifying and confirming the toxicant and/or an appropriate controlmeasure.g. The permittee shall complete the TRE and submit a Final Report on the TRE Activities no later than28 months from the last test day of the retest that confirmed significant lethal effects at the criticaldilution. The permittee may petition the Executive Director (in writing) for an extension of the 28-month limit. However, to warrant an extension the permittee must have demonstrated due diligencein their pursuit of the TIE/TRE and must prove that circumstances beyond their control stalled theTIE/TRE. The report shall provide information pertaining to the specific control mechanism(s)on-oeduct-i.n-9f effluent-toxicity-to-no-significant-lethality-at the critical dilution. The report will also provide a specific corrective action schedule forimplementing the selected control mechanism(s). A copy of the TRE Final Report shall also besubmitted to the U.S. EPA Region 6 office.h. Based upon the results of the TRE and proposed corrective actions, this permit may be amended tomodify the biomonitoring requirements, where necessary, to require a compliance schedule forimplementation of corrective actions, to specify a WET limit, to specify a BMP, and/or to specify CSlimits.Page 23 STP Nuclear Operating CompanyTPDES Permit No. WQOOO 1908000TABLE I (SWEET 1 OF 4)MYSID SHRIMP SURVIVAL AND GROWTHDates and TimesCompositesCollectedDate TimeNo. 1 FROM:No. 2 FROM:No. 3 FROM:DateTimeTO:TO:TO:Test initiated: anm/pm __dateDilution water used:.Receiving water___ Synthetic Dilution waterMYSID SHRIMP SURVIVAL-Pei&&n PctSiram Mexecent:I ': -...* coefficient of variation = standard deviation x 100/meanDATA TABLE FOR GROWTH OF MYSID SHRIMPAte-- -:w ":. i -b"s'Re'nl.. icateB. ..

Box 13087Austin, TX 78711-3087Re: Cooling Water Intake Structures Phase II RulesSouth Texas Project Electric Generating StationTPDES Permit No. 01908
Dear Mr. Holligan:
Thank you for meeting with my staff on May 15, 2007 to discuss the South Texas ProjectElectric Generating Station (STPEGS) cooling reservoir and other wastewater discharge permitissues. Based on our discussion, STP Nuclear Operating Company (STPNOC) is submitting thefollowing information regarding the Main Cooling Reservoir (MCR) and the applicability of theregulations for cooling water intake structures. We are confident that the South Texas ProjectStation (STP) complies with the regulation by employing a closed-cycle recirculating coolingsystem as defined in 40 CFR § 125.93. Pursuant to 40 CFR §125.94(a)(1)(i), cooling water flowfor this facility is commensurate with a closed-cycle recirculating cooling system, asdemonstrated below. Additional technical information is included in letters dated March 7, 2005and August 18, 2005 previously submitted to the Texas Commission on Environmental Quality(TCEQ).STP is located on 12,220-acres in Matagorda County, approximately 15 miles southwest of BayCity along the west bank of the Colorado River. The facility consists of two electric-generatingunits, which share a closed-cycle recirculating cooling reservoir. Water from the MCR is passedthrough the cooling loops of both units then returned to the MCR for heat dissipation beforecycling back through the cooling systems.The MCR is a perched, off-channel, on-site industrial cooling impoundment of approximately7,000 acres, impounding over 202,600 acre-feet of cooling water at its maximum operating level.Dikes are installed in the MCR that channel the water flow to maximize circulation time for heatdissipation before the water is recirculated back to the generating units. Blowdown from theMCR to the Colorado River has not occurred since March 1997. Should blowdown be requiredit would occur through an underground pipe that discharges back into the Colorado River. Thispoint is designated as Outfall 001 in the TPDES Permit No. 01908. The MCR is also equippedwith a gated spillway for emergency use. The MCR is not a "water of the U.S." as defined at 40CFR § 122.2. The MCR is not considered a "water of the State" based on internal and externaloutfall designations in the permit. The MCR is on private property and exists solely for Mr. Kelly HolliganMay 24, 2007Page 2industrial cooling. It is not a publicly managed water body and has no recreational uses. Thegeneral public has never had access to the NMICR nor is any planned in the foreseeable future.The only sources of new water to the MCR are direct rainfall and make-up water divertedperiodically from the Colorado River, primarily at high river flows. Water from the ColoradoRiver is pumped approximately I mile via a 108 inch pipe to the MCR. To protect inflows duringlow river flow conditions, the water right for STP includes a special provision to limit diversionfrom the Colorado River to 55% of the flow over 300 cubic feet per second, to protect inflowsduring low river flow conditions. Currently, the intake consists of irash racks, rotating screenswith 3/8 inch mesh and 4 pumps. In addition, the reservoir makeup pumping facility has thefollowing design:" The traveling water screens are flush with the river shoreline;* The maximum approach velocity to the traveling water screens is 0.5 feet per second;" Fish passageways were constructed in the wing walls between the traveling screens tofacilitate fish migration parallel to the screen surfaces; and* A sluice and discharge line was installed for the purpose of returning all impingedorganisms directly to the river, downstream of the intake structure, immediately afterbeing backwashed from the screens.The pumps are operated intermittently based on reservoir level, river flow, and the operability ofthe makeup pumping facility. A cooling reservoir evaporates less water per unit of heatdissipated than a cooling tower, thus dissolved solids build up more slowly over time. This iscomplemented by the designed seepage from the MCR, which maintains the structural integrityof the reservoir embankment. Rainfall further dilutes the dissolved solids in the MCR. Thesefactors minimize the blowdown and make-up required to maintain MCR water quality. As aresult, intake water flow for cooling purposes at STP reflects best technology available (closed-cycle recirculating systems) for minimizing adverse environmental impact.As was discussed in the May 15, 2007 meeting, several provisions of the Phase 11 rule are in theprocess of being suspended by the U.S. Environmental Protection Agency and the RegionalAdministrators have been authorized to review the applicability of the rule on a case by casebasis using Best Professional Judgment. Based on that authorization and the informationprovided, STPNOC is requesting that TCEQ designate the MCR as a closed-cycle recirculatingsystem. We are also requesting concurrence that the MCR does not meet the definition of a"water of the State". If you have any questions or require additional information, please contactMs. S. L. Dannhardt at (361) 972-8328.Sincerely,R. A.

Electricity Is generated from steam driven turbines.b. SIC Code(s) 4911NAICS Code(s) 221113 ,c. Describe the wastewater generating processes.Main Cooling Reservoir- Outfall 001Outfall 001 is Me discharge point for the 7,100-acre main cooling reservoir. This resetvo r Is part of the main recirculating cooling water loop used toremove heat from the steam-electric generating units. There has not been a discharge from Outfall 001 since March 1997 other than minor permittedleakage tihough the closed spillway gates and relief wells. If a discharge were to occur, blowdown from the main cooling reservoir would make up thelargest percentage of wastewater. A discharge from Outfall 001 would flow to the Colorado River (Colorado River Tidal in Segment 1401 of theColorado River Basin).All internal outfalls (Outfall 101, 201, 401, and 601) discharge to the main cooling reservoir. Outfall 501 would also discharge to the reservoir viaOutfall 101. but has not discharged since 1992.Low Volume Wastewater (Outfalla 101 and 201)Low volume wasutwator results from water treatment operations, boiler blowdown. HVAC bbowdown, floor drains and SPCC sources and theirassociated oily watet treatment system discharges, and other miscellaneous Sources. Boiler blowdown Is from one auxiliary steam boiler, released toreduce impurities In the water that can cause corrosion and boiler tube fallure. Service water Is denineralzed and regeneration of the demineralzerresin beds produces an acidic and caustic wastewater that is treated at the neutralization basins along with boiler blowdown. The floor drain systemcaptures condensate and water from production and maintenance areas that may contain oil or grease, which Is then transported to the oily wastetr"atment system where the oil is separated from the water. The first flush of storm water from production and storage area is also treated Inthe oily waste system. Other non-process storm water flow is directed through designated storm water outrfaIl.Treated Domestic Wastewater (Out lsts 401 and 601)Domestic wastewater Is treated onsite in two package treatment systems consisting of aeration, clarificaion, and disinfection. Car wash water, airconditioning condensate, HVAC cooling tower blowdown, and storm water are commingled with the domestic wastewater puior to treatment.Metal Cleaning Waste (Outfalla 501)Metal cleaning waste has not been discharged since 1992- Cleaning of metal using chemical or non-chemical liquids produces a waste that would bedischarged through Outfall 501 to the neutralization basins (Outfall 1t1). Storm water may also be discharged through Outfall 501.d.

Box 13087Austin, TX 78711-3087Re- Cooling Water Intake Structures Phase II RulesSouth Texas Project Electric Generating StationTPDES Permit No. 01908
Dear Mr. Holligan:
Thank you for meeting with my staff on May 15, 2007 to discuss the South Texas ProjectElectric Generating Station (STPEGS) cooling reservoir and other wastewater discharge permitissues. Based on our discussion, STP Nuclear Operating Company (STPNOC) is submitting thefollowing information regarding the Main Cooling Reservoir (MCR) and the applicability of theregulations for cooling water intake structures. We are confident that the South Texas ProjectStation (STP) complies with the regulation by employing a closed-cycle recirculating coolingsystem as defined in 40 CFR §125.93. Pursuant to 40 CFR §125.94(a)(1)(i), cooling water flowfor this facility is commensurate with a closed-cycle recirculating cooling system, asdemonstrated below. Additional technical information is included in letters dated March 7, 2005and August 18, 2005 previously submitted to the Texas Commission on Environmental Quality(TCEQ).STP is located on 12,220-acres in Matagorda County, approximately 15 miles southwest of BayCity along the west bank of the Colorado River. The facility consists of two electric-generatingunits, which share a closed-cycle recirculating cooling reservoir. Water from the MCR is passedthrough the cooling loops of both units then returned to the MCR for heat dissipation beforecycling back through the cooling systems.The MCR is a perched, off-channel, on-site industrial cooling impoundment of approximately7,000 acres, impounding over 202,600 acre-feet of cooling water at'its maximum operating level.Dikes are installed in the MCR that channel the water flow to maximize circulation time for heatdissipation before the water is recirculated back to the generating units. Blowdown from theMCR to the Colorado River has not occurred since March 1997. Should blowdown be requiredit would occur through an underground pipe that discharges back into the Colorado River. Thispoint is designated as Outfall 001 in the TPDES Permit No. 01908. The MCR is also equippedwith a gated spillway for emergency use. The MCR is not a "water of the U.S." as defined at 40CFR § 122.2. The MCR is not considered a "water of the State" based on internal and externaloutfall designations in the permit. The MCR is on private property and exists solely for Mr. Kelly HolliganMay 24, 2007Page 2industrial cooling. It is not a publicly managed water body and has no recreational uses. Thegeneral public has never had access to the MCR nor is any planned in the foreseeable future.The only sources of new water to the MCR are direct rainfall and make-up water divertedperiodically from the Colorado River, primarily at high river flows. Water from the ColoradoRiver is pumped approximately I mile via a 1 0 inch pipe to the MCR. To protect inflows duringlow river flow conditions, the water right for STP includes a special provision to limit diversionfrom the Colorado River to 55% of the flow over 300 cubic feet per second, to protect inflowsduring low river flow conditions. Currently, the intake consists of trash racks, rotating screenswith 3/8 inch mesh and 4 pumps. In addition, the reservoir makeup pumping facility has thefollowing design:" The traveling water screens are flush with the river shoreline;* The maximum approach velocity to the traveling water screens is 0.5 feet per second;* Fish passageways were constructed in the wing walls between the traveling screens tofacilitate fish migration parallel to the screen surfaces; and" A sluice and discharge line was installed for the purpose of returning all impingedorganisms directly to the river, downstream of the intake structure, immediately afterbeing backwashed from the screens.The pumps are operated intermittently based on reservoir level, river flow, and the operability ofthe makeup pumping facility. A cooling reservoir evaporates less water per unit of heatdissipated than a cooling tower, thus dissolved solids build up more slowly over time. This iscomplemented by the designed seepage from the MCR, which maintains the structural integrityof the reservoir embankment. Rainfall further dilutes the dissolved solids in the MCR. Thesefactors minimize the blowdown and make-up required to maintain MCR water quality. As aresult, intake water flow for cooling purposes at STP reflects best technology available (closed-cycle recirculating systems) for minimizing adverse environmental impact.As was discussed in the May 15, 2007 meeting, several provisions of the Phase II rule are in theprocess of being suspended by the U.S. Environmental Protection Agency and the RegionalAdministrators have been authorized to review the applicability of the rule on a case by casebasis using Best Professional Judgment. Based on that authorization and the informationprovided, STPNOC is requesting that TCEQ designate the MCR as a closed-cycle recirculatingsystem. We are also requesting concurrence that the MCR does not meet the definition of a"water of the State". If you have any questions or require additional information, please contactMs. S. L. Dannhardt at (361) 972-8328.Sincerely,R A.

Dear Mr. Gangluff:
I received your letter dated May 24, 2007, requesting that the Main Cooling Reservoir (MCR) bedesignated as a closed-cycle recirculating system and as not water in the state.The Texas Commission on Environmental Quality (TCEQ) does not have an official method of"designating" a facility's operation as a closed-cycle recirculating system. However, we have reviewedthe information you submitted and based on our best professional judgement, we consider your facility tobe a closed-cycle recirculating system. As mentioned in your letter, the federal rule governing the 316(b)Phase II cooling water intakes is currently in the process of being suspended. For the time being,implementation of the 316(b) requirements will be based on best professional judgement (BPJ) andsubject to EPA Region VI review.We also concur that the Main Cooling Reservoir (MCR) at your facility does not meet the definition ofwater in the state.If you have any questions, please contact me at (512) 239-2369.Sincerely,Kelly Holligan, LeaderIndustrial TeamWater Quality DivisionKH/jpP.O.

Submission of driller's log records upon completion of adrilled water well became mandatory in 1985. The state of Texas has processed these records into several different filingsystems within two state regulatory authorities. The water well files, records and map locations are maintained by the TexasCommission on Environmental Quality (TCEQ) and the Texas Water Development Board (TWDB). Actual water well sitelocations of this report are geocoded and geoplotted directly from the drilling records, drilling schedules, and driller's logs andmaps submitted by the water well driller and maintained at these two primary water well regulatory authorities. Below is adescription of the filing systems utilized for well drilling records.Texas Water Development Board (TWDB)The Texas Water Development Board maintains two datasets of located water well records:TWDB Groundwater Data-These well files are water well site locations that have been verified with a field inventoryinspection by TWDB personnel. The wells are assigned a State Identification Number unique to that well (ex. 65-03-401) andplotted on county base maps, U.S.G.S. 7.5 minute topographical quadrangle maps, as well as in-house and on linegeographic information systems. Records may also include analytical data attached with each drilling record.TWDB Submitted Drillers Reports- A Database created from the online Texas Well Report Submission and Retrieval System(A cooperative TDLR. TWDB system) that registered water-well drillers use to submit their required reports. Reports thatdrillers submit by mail are geoplotted/geocoded by a TWDB staff member. These wells are assigned a unique trackingnumber by the Texas Well Report Submission and Retrieval System. This system was introduced in February 2001 as anoption for drillers to use, and will be mandatory in the future.Texas Commission on Environmental QualityThe Texas Commission on Environmental Quality (TCEQ) maintains two datasets of water well records.Water Utility Database*(WUD) -This database contains a collection of data from Texas Water Districts, Public Drinking WaterSystems and Water and Sewer Utilities who submit information to the TCEQ. These wells are assigned unique numbers withcorrelate to the Public Water System they act as a source for (example- $2200199A, G2200322A). The WUD does notcontain Drillers Reports or analytical data. This data was provided to Banks in digital format.TCEQ Central Records-Several different types of Driller's Reports are filed with TCEQ Central Records according to theState Grid Number.Plotted water well files are water well site locations that have been determined from map information submitted on water welllogs and subsequently plotted on TWDB county highway base maps. The accuracy and location of these wells is relative tothe information provided on the drillers report. TWDB assigned letters to the correlating grid number to identify these wells(example -65-59-1A). In some instances, a single well number can represent more than one well location. This type ofmapping and filing procedure ceased in June 1986.Partially numbered water wells -Well Reports that were provided a State Identification Number by the TWDB whichestablishes the well location somewhere within a 2.5 minute quadrant of a 7.5 minute quadrangle map. This method was thestandard procedure from 1986 through 1991. From 1991 to the 2001, Texas Well Reports contain a grid location box, wheredrillers are provided a place to mark an X where within the 2.5 minute quadrant is located. These locations have not beenverified by the state.Unnumbered water well files are water well site locations that have been processed since June 1990. These well records arefiled solely on their county location and are not provided a State Identifiation Number nor are they mapped.DisclaimerBanks Environmental Data has performed a thorough and diligent search of all wells recorded with the Texas WaterDevelopment Board and the Texas Commission on Environmental Quality. All mapped locations are based on informationobtained from the TWDB and the TCEQ. Although Banks performs quality assurance and quality control on all researchprojects, we recognize that any inaccuracies of the records and mapped well locations could possibly be traced to theappropriate regulatory authority or the water well driller. Many water well schedules may have never been submitted to theregulatory authority by the water well driller and, thus. may explain the possible unaccountability of private drilled wells. It isuncertain if the above listing provides 100% of the existing well locations within the area of review. Therefore, BanksEnvironmental Data cannot gaurantee the accuracy of the data or well location(s) of those maps and records maintained byTexas' regulatory authorities.1601 Rio Grande Suite 500 Austin, Texas 78701PH 512.478.0059 FAX 512.478.1433 E-mail banks@banksinfo.com THU.,F Il ~ ll ~Irl* £V. & 7;V , J flHMATERIAL SAFETY DATA SHEETALTI VIA Sodium Hypochlorite Solution 10-15%ALTIVIA 24 Hour Emergency Phone Number: 713-636-3189Transportation Emergencies CHEMTREC: 800-424-9300SECTION 1: PRODUCT AND COMPANY IDENIFICATIONPRODUCT NAME: Sodium Hypochloito Solution 10-16%CHEMICAL NAME/ FAMILY: Sodium HypochloriteTRADE NAMESI SYNONYMS: Bleach; hypochlorous acid, sodium salt, Soda bleach; sodium oxychloridePRODUCT USE: Bleaching agent, chemical intermnediate, disinfectant.MOLECULAR FORMULA: NaOCIMANUFACTURER; ALTIVIA, 1100 Louisiana, Suite 3160, Houston, TX 77002SECTION 2: COMPOSMONw INFORMATION ON INGREDIENTSCHEMICAL NAME CAS NUMBER % RANGESodium Hypochlorite 7651-52-9 9 16.5Sodium Hydroxide 131D-73-2 0-1%Water 7732-18-5 BalanceDonates chwmk:ll subet 10 r trfnr4s ol Section 313 of "I III Of Mhe 1986 Sipedurx Amonfrwrls wad ResJuttWwliOn Act(SARA) and 40 CFR P&At 372.SECTION 3: HAZARDS IDENTIFICATIONEMERGENCY OVERVIEWDangarl Corrosive.
