Form 2C, Attachment 1 Item II.C. Intermittent and Miscellaneous Flows Outfall Description of Flow 002/003 - Units 1 and 2 Cooling Tower These points represent the blowdown from the Unit 1 and Slowdown Unit 2 Turbine Plant Cooling Towers. Each tower recirculates river water used to cool turbine condensate via a heat exchanger. Periodic blowdown or discharge from the system is necessary to maintain the cycles of concentration in the circulating water system to prevent the build-up of solids. The estimated flow rate during a blowdown event is approximately 4,000 gpm for an approximate duration of 3-4 hours. The discharge is routed to the Slowdown Sump Mixing Box which is a final mixing chamber.

002N003A- Units 1 and 2 Cooling These points are utilized for cooling tower basin Tower Overflow to Storm overflow to storm drains. Overflow events occur Drains infrequently and are generally the result of an operational problem with the system. The estimated flow rate in the event of an overflow of the basins is 2,000 gpm for an approximate duration of 1-2 hours.

004/005- Units 1 and 2 Waste Water These points represent the permanent collection basins Retention Basins (420,000 gallon capacity each) for plant low volume waste streams. The basins provide aeration and retention time for the wastes. Each basin has two transfer pumps which discharge the effluent to the Slowdown Sump Mixing Box. The pumping capacity will all four pumps running is rated at 2,600 gpm.

006 - Sewage Treatment Plant This point represents the collection point for discharge Emergency Overflow from the plant sewage treatment plant in the event of an emergency. During normal operation, discharge from the sewage treatment plant is routed to the Waste Water Retention Basins. The discharge during emergency overflow is approximately 125 gpm, and emergency overflow events occur infrequently.

007/008 - Units 1 and 2 Liquid Radwaste These points represent wastewater generated in the Systems Discharge Reactor Building and Auxiliary Building which may be slightly radioactive. Radiologically contaminated fluids are treated and monitored for radioactivity levels in accordance with Nuclear Regulatory Commission (NRC) regulations prior to release. The maximum flow is approximately 200 gpm (combined for both units).

Form 2C, Attachment 1 (Continued)

Item II.C. Intermittent and Miscellaneous Flows Outfall Description of Flow 009 - Nuclear Service Cooling Towers This point represents the system which supplies cooling (Units 1 and 2) water for safety related equipment. Each unit has its own separate NSCW system which consists of two cooling towers. The discharge of each tower is routed to the Slowdown Sump Mixing Box. The maximum combined flow for both units is approximately 500 gpm.

010- Radwaste Dilution Flow This point represents an internal stream consisting of river water with no additives. The discharge is routed to the Slowdown Sump Mixing Box to provide dilution water for radwaste discharges. The maximum flow for this discharge point is approximately 46,000 gpm. *SNC requests that this outfall be removed from the final permit since no treatment is performed.

011 - Intake Screen Backwash This point represents a discharge consisting only of river water with no additives. The flow is used to backwash the intake screens, and is returned directly to the Intake Canal. Maximum flow for this discharge point is approximately 1,256 gpm.

If you are not requ1red to mark column 2-a (secondary industries, nonprocess wastewater outfalls, and nonreqwred GCIMS I fractions). mark "X" in column 2-b for each pollutant you know or have reason to believe is present. Mark *x* in column 2-c for each pollutant you believe IS absent. If you mark column 2a for any pollutant, you must provide the results of at least one analysis for that pollutant. If you mark column 2b for any pollutant, you must provide the results of at least one analysis for that pollutant if you know or have reason to believe it will be discharged in concentrations of 10 ppb or greater. If you mark column 2b for acrolein , acrylonitrile, 2.4 dimtrophenol , or 2-methyl-4 , 6 dinitrophenol, you must proVIde the results of at least one analysis for each of these ,

pollutants which you know or have reason to believe that you discharge in concentrations of 100 ppb or greater. Otherwise, for pollutants for which you mark column 2b, you must either submit at least one analysis or briefly describe the reasons the pollutant IS expected to be discharged. Note that there are 7 pages to this part; please review each carefully. Complete one table (all 7 pages) for each outfall . See instructions for additional details and requirements.

Mark "X" in column 2-a for all such GC/MS fractions that apply to your industry and for ALL toxic metals, cyanides, and total phenols. If you are not required to mark column 2-a (secondary industries, nonprocess wastewater outfalls, and nonrequired GC/MS fractions), mark *x* in column 2-b for each pollutant you know or have reason to believe is present. Mark *x* in column 2-c for each pollutant you believe is absent. If you mark column 2a for any pollutant, you must provide the results of at least one analysis for that pollutant. If you mark column 2b for any pollutant, you must provide the results of at least one analysis for that pollutant if you know or have reason to believe 1t will be discharged in concentrations of 10 ppb or greater. If you mark column 2b for acrolein, acrylonitrile, 2.4 dimtrophenol , or 2-methyl-4 , 6 dinitrophenol, you must provide the results of at least one analysis for each of these pollutants which you know or have reason to believe that you discharge in concentrabons of 100 ppb or greater.

NUMBER (copy from Item I <![Form I) OUTFALL NUMBER GA0026786 006 PART C- If you are a primary industry and this outfall contains process wastewater, refer to Table 2c-2 in the mstructions to determtne which of the GC/MS fractions you must test for. Mark "X" in column 2-a for all such GC/MS fractions that apply to your industry and for ALL toxic metals, cyanides, and total phenols. If you are not required to mark column 2-a (secondary industries, nonprocess wastewater outfalls, and nonrequired GCIMS fractions), mark "X" in column 2-b for each pollutant you know or have reason to believe is present. Mark "X" in column 2-c for each pollutant you believe is absent. If you mark column 2a for any pollutant, you must provide the results of at least one analysis for that pollutant. If you mark column 2b for any pollutant, you must provide the results of at least one analysis for that pollutant if you know or have reason to believe tt will be discharged in concentrations of 10 ppb or greater If you mark column 2b for acrolein , acrylonitrile, 2,4 dinitrophenol, or 2-methyl-4, 6 dinitrophenol, you must provule the results of at least one analysis for each of these pollutants which you know or have reason to believe that you dtscharge in concentrations of 1DO ppb or greater. Otherwtse, for pollutants for which you mark column 2b, you must either submit at least one analysis or briefly describe the reasons the pollutant is expected to be dtscharged. Note that there are 7 pages to this part; please revtew each carefully. Complete one table (a// 7 pages) for each outfall . See instructions for additional details and requirements.

NUMBER (copy ;;om/lem I of Form I) OUTFALL NUMBER GA0026786 011 PART C- If you are a primary industry and this outfall contains process wastewater, refer to Table 2c-2 in the instructions to determine which of the GC/MS fractions you must test for. Mark "X" in column 2-a for all such GC/MS fractions that apply to your industry and for ALL toxic metals, cyanides, and total phenols. If you are not required to mark column 2-a (secondary industries, nonprocess wastewater outfalls, and nonrequired GC/MS fractions) , mark "X" in column 2-b for each pollutant you know or have reason to believe is present. Mark "X" in column 2-c for each pollutant you believe Is absent. If you mark column 2a for any pollutant, you must provide the results of at least one analysis for that pollutant. If you mark column 2b for any pollutant, you must provide the results of at least one analysis for that pollutant if you know or have reason to believe it will be discharged In concentrations of 10 ppb or greater. If you mark column 2b for acrolein, acrylonitrUe, 2,4 dinitrophenol, or 2-methyl-4, 6 dinitrophenol , you must provide the results of at least one analysis for each of these pollutants which you know or have reason to believe that you discharge in concentrations of 100 ppb or greater. Otherwise, for pollutants for which you mark column 2b, you must either submit at least ooe analysis or bnefly describe the reasons the pollutant is expected to be discharged. Note that there are 7 pages to this part; please review each carefully. Complete one table (all 7 pages) for each outfall . See Instructions for additional details and requirements.

6. Operate any other combination of technologies, management practices and operational measures that the Director determines is the best technology available for impingement reduction; or (a) In the case of Option (6), the facility must submit a site-specific impingement study including two years of biological data collection demonstrating that the operation of the system of technologies, operational measures and best management practices has been optimized to minimize impingement mortality. If this demonstration relies in part on a credit for reductions in the rate of impingement already achieved by measures taken at the facility, an estimate of those reductions and any relevant supporting documentation must be submitted. The estimated reductions in rate of impingement must be based on a comparison of the system to a once-through cooling system with a traveling screen whose point of withdrawal from the surface water source is located at the shoreline of the source waterbody.

D Currently in operation 0 Request a compliance schedule

7. Achieve the specified impingement mortality performance standard.

(a) The impingement mortality performance standard in (7) requires that a facility must achieve a 12 -month impingement mortality performance of all life stages of fish and shellfish of no more than 24 percent mortality, including latent mortality, for all non-fragile species that are collected or retained in a sieve with maximum opening dimension of 0.56 inches and kept for holding period of 18 to 96 hours0.00111 days 0.0267 hours 1.587302e-4 weeks 3.6528e-5 months . The Director may, however, prescribe an alternative holding period.

The 12-month average of impingement mortality is calculated as the sum of total impingement mortality for the previous 12 months divided by the sum of total impingement for the previous 12 months. A facility must choose to demonstrate compliance with this requirement for the entire facility, or for each individual cooling water intake structure. Biological monitoring must be completed at a minimum frequency of monthly.

The owner or operator of a new unit at an existing facility must achieve one of two compliance alternatives under the national BTA standards for impingement mortality and entrainment for new units at existing facilities at§ 125.94(e) (hereafter, new unit standards).

0 Option No. 1 You must reduce AIF at the new unit, at a minimum, to a level commensurate with that which can be attained by the use of a closed-cycle recirculating system as defined at§ 125.92(c)(l).

0 Option No. 2 You must demonstrate to the Director that it has installed and will operate and maintain, technological or other control measures that reduce the level of adverse environmental impact from any cooling water intake structure used to supply cooling water to the new unit to a comparable level to that which would be achieved throughflow reductions commensurate with the use ofa closed-cycle recirculating system.

Under this alternative, the owner or operator of a facility must demonstrate entrainment mortality reductions that are equivalent to 90 percent or greater of the reduction that could be achieved through compliance with the first alternative entrainment standard for new units.

Supporting Information Required Under the Clean Water Act Section 316(b)

Vogtle Electric Generating Plant NPDES No. GA0026786 Submitted by Southern Nuclear Operating Company A Southern Nuclear September 2017

CWA Section 316(b) Supporting Information Vogtle Electric Generating Plant Units 1 & 2 Introduction Georgia Power Company (GPC), Oglethorpe Power Corporation, the Municipal Electric Authority of Georgia, and the City of Dalton, Georgia, an incorporated municipality in the State of Georgia acting through its Board of Water, Light, and Sinking Fund Commissioners (Dalton Utilities), are the owners of the Vogtle Electric Generating Plant (VEGP) site and its existing facilities (Units 1&2).

Southern Nuclear Operating Company (SNC) is the plant licensee and operates VEGP Units 1&2 under contract with the owners. GPC and SNC are subsidiaries of Southern Company. SNC is the licensed operator for all existing Southern Company nuclear generating facilities.

The 3,169 acre VEGP site is on the southwest side of the Savannah River in eastern Burke County, in east-central Georgia. The site is approximately 100 miles northwest of Savannah, Georgia, and approximately 26 miles southeast of Augusta, Georgia, and across the river from the U.S.

Department of Energy's Savannah River Site (SRS) in Barnwell County, South Carolina.

This document is intended to satisfy the additional permit application requirements under 316(b).

CWA Section 316(b) Supporting Information Vogtle Electric Generating Plant Units 1 & 2 CWA Section 316(b) Requirements According to the Clean Water Act. Section 316(b). existing facilities with a cumulative design intake flow greater than 2 MGD is subject to the BTA (best technology available) standards for impingement under paragraph 40 CFR 125.94(c) and entrainment under40 CFR 125.94(d). which include the following requirements:

(1) BTA Standards for Impingement Mortality- Compliance must be met with one of the alternatives listed in paragraphs (c)(1) through (7) of this section (40 CFR 125.94(c)).

(2) BTA Standards for Entrainment for Existing Facilities- The Director must establish BTA standards for entrainment for each intake on a site-specific basis (40 CFR 125. 94(d)).

The following application is intended to comply with the requirements for all existing facilities specific to 316(b), under 40 CFR 122.21(r)(1 )(ii)- Existing Facilities. lnfonnation meeting the requirements under sections 122.21(r)(2J through (r)(BJ is included below.

40 CFR 122.21 (r)(2) - Source Water Physical Data All existing facilities must provide the source water physical data required at 40 CFR 122.21 (r)(2) in their penn it applications. These data are needed to characterize the facility and evaluate the type of waterbody and species affected by the cooling water intake structure. This infonnation will also be used by the penn it writer to evaluate the appropriateness of the design and construction technologies selected by the applicant for use at their site in subsequent pennit proceedings. Specific data items that must be submitted include:

(i) A narrative description and scale drawings showing the physical configuration of all source water bodies used by the facility. including areal dimensions. depths. salinity and temperature regimes.

and other documentation that supports detennination of the water body type where the cooling water intake structure is located:

The 3,169-acre VEGP site occupies a Coastal Plain bluff on the southwest bank of the Savannah River in eastern Burke County, Georgia. VEGP Units 1&2 is approximately 220 feet above mean sea level (msl). This site is at River Mile (RM) 151; approximately 30 river miles upstream of the U.S. Highway 301 Bridge and directly across the river from SRS. The site is approximately 100 miles northwest of Savannah, Georgia, and approximately 26 miles southeast of Augusta, Georgia.

(NRC 2008)

VEGP Units 1&2 share a common CWIS and certain support structures such as office buildings, water, wastewater, and waste-handling facilities. VEGP Units 1&2 uses a closed-cycle, recirculating cooling system which includes two concrete natural-draft hyperbolic cooling towers (one per unit) and a common CWIS and discharge line. The Savannah River is the source for make-up water for the circulating water cooling system and provides water to replace cooling tower evaporative water losses, drift losses, and blowdown discharge.

The Savannah River is a freshwater river with portions of its watershed in South Carolina, North Carolina and Georgia. The total size of the Savannah River watershed is approximately 10,579 mi 2 ;

5870 mi 2 of which are in Georgia; 4530 mj2 in South Carolina; and 179 mi 2 in North Carolina (USACE 1996). The confluence of the Seneca and Tugaloo Rivers, which is now part of Hartwell Reservoir, is considered the upstream end of the Savannah River (USACE 1996). The Savannah River flows 288.9 mi from Hartwell Dam to its mouth, where it enters the Atlantic Ocean at Tybee 3

CWA Section 316(b) Supporting Information Vogtle Electric Generating Plant Units 1 & 2 Island, Georgia. The VEGP site is at River Mile (RM) 151 . Three large dams, constructed and operated by the United States Army Corps of Engineers (USAGE), lie upstream of the site; Hartwell Dam, at Savannah RM 288.9, is 138 mi upstream of the VEGP site and is capable of storing 4230 million m 3 (3,430,000 acre-feet (ac-ft)) of water (USACE 1996). The dam was completed and began filling in February 1961 (USACE 1996). Richard B. Russell Dam, at Savannah RM 259.1, is 108 mi upstream of the VEGP site and is capable of storing 1836 million m 3 (1 ,488,155 ac-ft) of water (USACE 1996). This was the last of the three large dams to be completed, and it began filling in October 1983. At Savannah RM 221.6, J. Strom Thurmond Dam is 71 mi upstream of the VEGP site. Its reservoir is capable of storing 4564 million m 3 (3, 700,000 ac-ft) of water. J. Strom Thurmond Dam, first of the three dams to be completed, began filling in December 1951 (USACE 1996).

Between J. Strom Thurmond Dam and the VEGP site lies Stevens Creek Dam (RM 208.1), the city of Augusta (approximately RM 200), New Savannah Bluff Lock and Dam (RM 187.7), and the mouths of several small creeks (USACE 1996). Stevens Creek Dam, operated by SCE&G, functions as are-regulating reservoir to mitigate the large flow variations from J. Strom Thurmond Dam and to generate hydroelectric power. New Savannah Bluff Dam, constructed and operated by USAGE, is part of the inactive Savannah River Below Augusta Navigation Project (USACE 1996).

Channel modifications have been made to the Savannah River to allow for a 9-ft deep by 90-ft wide navigation channel from the Savannah Harbor to the city of Augusta. By 1980, shipping along the river had essentially ceased, and maintenance of the channel was discontinued (USACE 2006a, p.

6). Consequently, Hartwell, Russell, and Thurmond dams are no longer operated for navigation, and minimum discharges from J. Strom Thurmond Dam are based on the needs of downstream water users with less concern for navigation (USACE 2006a).

In 2006, SNC performed a bathymetric survey in the Savannah River adjacent to the VEGP site (Figure 1 - Savannah River Bathometry at VEGP). The Savannah River in the vicinity of the VEGP Units 1&2 CWIS is approximately 325 ft wide with an average water depth between 7 and 10 feet.

The climate in the upper Savannah River watershed is temperate, with generally mild winters and long summers. The annual mean temperature for the basin is 60°F. January, which is usually the coldest month of the year, frequently has night temperatures of 20°F or lower. July and August, the hottest months of the year, have many days with temperatures over 90°F. In the lower section of the basin, the winters are milder and the summer temperatures higher (USACE 1996).

Savannah River water temperature data were collected monthly by the Georgia Department of Natural Resources (GDNR) at Shell Bluff Landing, approximately 11 river miles upstream of the VEGP site, from January 30, 1973 to August 13, 1996 (Frazier 2006). Savannah River water temperature data are also collected from multiple locations as part of the ongoing environmental monitoring at the Savannah River Site. From the 2009 data (SRS 201 0), the following water temperature statistics were generated:

CWA Section 316(b) Supporting Information Vogtle Electric Generating Plant Units 1 & 2 (ii) an identification and characterization of the source waterbody's hydrological and geomorphological features. as well as the methods used to conduct any physical studies to determine the intake's area of influence within the waterbody and the results of such studies: and As mentioned previously, the Savannah River watershed extends into the mountains of North Carolina, South Carolina, and Georgia near Ellicott Rock, the point where the borders of those three states meet.

Within the three states, the Savannah River basin includes portions of 44 counties and two major metropolitan centers, Augusta and Savannah. The lower 50 mi reach of the Savannah River is tidally influenced (USACE 1996). The Savannah River watershed and sub-basins, are delineated by the National Weather Service (NWS 2005) and further subdivided by USGS Hydrologic Unit Code (HUC-12) sub-basins (USGS 2006f). The Savannah River at the VEGP site lies within HUC-12- 030601061101.

The Savannah River watershed traverses three distinct physiographic provinces: the Mountain, Piedmont, and Coastal Plain. The Mountain and Piedmont provinces are within the Appalachian Mountain range, with the border between them extending from northeast to southwest, crossing the Tallulah River at Tallulah Falls (the Tallulah River and the Chattooga River form the Tugalo). The Fall Line, or division between the Piedmont province and the Coastal Plain province, also crosses the basin in a generally northeast to southwest direction, near Augusta, Georgia (USACE 1996).

Watershed elevations range from 5,030 ft msl at Little Bald Peak in North Carolina, to near sea level at Savannah and sea level where the river meets the ocean. The approximate range of elevations for each physiographic region is (USACE 1996): 5,030 to 1,800 ft msl within the Mountain province, 1,800 to 500 ft msl within the Piedmont province, and 500 to 0 ft msl within the Coastal Plain province.

The Savannah River, together with certain of its tributaries, forms the border between the states of Georgia and South Carolina. The confluence of the Seneca and Tugaloo rivers, formerly known as "The Forks" but now inundated by Hartwell Lake, marks the upstream end of the Savannah River.

The length of the Savannah River from The Forks to its mouth on the Atlantic Ocean is about 312 mi (USACE 1996).

The following principal streams make up the Savannah River stream system (USACE 1996):

The Tallulah and Chattooga Rivers combine to form the Tugaloo River at River Mile 358.1

Twelve Mile Creek and the Keowee River join to form the Seneca River at River Mile 338.5 .

The Tugaloo and Seneca rivers join to form the Savannah River proper at River Mile 312.1, at the point known as The Forks.

The entire 312-mi length of the Savannah River is regulated by a series of three USAGE multipurpose projects, forming a chain along the Georgia-South Carolina border 120 mi long. The three lakes, from upstream to downstream, are:

Hartwell Lake and Dam, with 3,430,000 ac-feet of storage

Richard B. Russell Lake and Dam, with 1,488, 155 ac-ft of storage

J. Strom Thurmond (also known as Clarks Hill) Lake and Dam, with 3,700,000 ac-ft of storage.

CWA Section 316(b) Supporting Information Vogtle Electric Generating Plant Units 1 & 2 There are generally two periods of maximum rainfall in the upper basin: February-March and July-August, although heavy rainfall has occurred in practically every month. The mean annual precipitation decreases from 83.5 in. at the upper end of the watershed, near Highlands, North Carolina, down to 49.2 in. at Savannah, Georgia (USACE 1996).

The VEGP site is bordered on the east by the Savannah River and by Beaverdam Creek to the south. The SRS is directly across the river to the east. The site is on a high, steep bluff on the west bank of the Savannah River. State Road 23 (River Road) runs roughly parallel to the river, about 4 miles from the VEGP site. It runs along the ridge line that separates local drainage running northeast to the river from runoff draining generally to the southwest. An unnamed, highly incised creek drains the area of the site north of River Road into the Savannah River just upstream of the site. To the west, the site is drained by the Red Branch and Daniels Branch, which join with Beaverdam Creek just upstream of Telfair Pond, south of the site. Beaverdam Creek intercepts three streams draining runoff from north of State Road 23 before it reaches the site. (Southern 2008a, p. 2.3.1-3)

In May, 2008, Southern Company personnel completed a hydraulic zone of influence survey at the VEGP Units 1&2 CWIS. The Savannah River adjacent to the intake canal was surveyed both upstream and downstream over a sufficient distance to define the hydraulically-affected zone.

Acoustic Doppler Current Profiling (ADCP) data were collected by navigating a boat-mounted ADCP unit parallel to the shoreline. The first transect was within 10 feet of the river bank of VEGP Units 1&2 cooling water intake canal and subsequent transects were performed at 10 foot intervals and concluded halfway across the river channel. Data from 11 parallel transects were collected and used to determine the hydraulic zone of influence. The boundary demarcating the area of greatest extent of hydraulic influence from VEGP Units 1&2 was determined to be where the occurrence of water velocities and vectors were predominantly unrelated to the VEGP Units 1&2 CWIS.

(Southern 2008b, Enclosure 1, p. 2)

During normal operations of VEGP Units 1&2, only two of the four available water intake pumps are in operation. When the ADCP survey was conducted, three water intake pumps were operating.

Based on a maximum of four operating pumps, intake flows at full pump design capacity would be 127 MGD or 196 cfs. During the May, 2008 survey, the intake flow was calculated at 71.2 MGD or 110 cfs (56% of full capacity). At the time of the survey, the average flow on the Savannah River at the Vogtle site was 4,482 cfs. Six ADCP transects were completed to measure the Savannah River flow (three prior to survey and three after survey). The river flows varied by less than 2% (4,443 -

4,506 cfs) during the monitoring event. (Southern 2008b, Enclosure 1, p. 2)

With the intake pump rates and Savannah River flows during the May, 2008 survey event as described, the VEGP Units 1& 2 CWIS zone of hydraulic influence occupied a total area of 1.10 acres, which includes the entire VEGP Units 1&2 intake canal and extends a short distance into the Savannah River. The area of VEGP Units 1&2 CWIS hydraulic influence in the Savannah River itself accounted for 12% (0.14 acres) of the total zone of hydraulic influence (Southern 2008b, , p. 2).

Information on the design of the intake structure and its location in the water column will allow the permit writer to evaluate which species or life stages would potentially be subject to impingement and entrainment. A diagram of the facility's water balance would be used to identify the proportion of intake water used for cooling.

make-up. and process water. The water balance diagram also provides a picture of the total flow in and out of the facilitY. allowing the permit writer to evaluate compliance with the 40 CFR 125.94 requirements. Specific data on the intake structure include:

(i) a narrative description of the configuration of each cooling water intake structures and where it is located in the waterbody and in the water column:

The VEGP Units 1&2 CWIS consists of the intake canal, the intake structure, the make-up pumps, and the chlorination system. The location of the intake system for VEGP Units 1&2 is shown in Figures 2 through 4. Engineering drawings of the CWIS and canal are also referenced in Item (5) below and show the CWIS and canal in greater detail.

VEGP employs a closed-cycle heat dissipation system designed to remove waste heat from the steam condensers. The circulating water system includes the intake canal, a four-bay intake structure, four intake pumps, condensers, two natural draft cooling towers, and an underground single port discharge pipe into the Savannah River. The intake canal is a 365-foot long, 140-foot wide structure with an earthen bottom at approximately 67 ft above mean sea level (MSL) and vertical sheet pile sides extending to 98ft MSL. The intake canal has a skimmer weir (elevation 78 ft MSL) with guide vanes at the river entrance. The skimmer weir consists of both fixed and removable sections with the fixed sections having elevations below 78 ft MSL. A canal weir is located approximately 100 ft inside the canal. Silting protection is provided by the sedimentation basin formed by the skimmer weir and canal weir. (Southern 2007, p. 3.1-2)

The intake structure consists of four bays, each with stop logs, a trash rack, traveling screens, and one pump. Intake velocity through the trash racks is less than 0.5 feet per second. The trash racks are made of vertical flat bars with a cross section of 3.5 inches by 0.5 inches and 3 inches on center. Traveling screens are annealed type 304 stainless steel with 3/8 inch mesh. Debris is rinsed from the traveling screen and sluiced into a debris basket located in a debris basin on the downstream side of the intake structure. The basket is emptied periodically and the contents disposed at an upland disposal site. (Southern 2007, p. 3.1-2)

(ii) latitude and longitude in degrees. minutes. and seconds for each of your cooling water intake structures:

The VEGP Units 1&2 CWIS is located at N 33° 08' 59.6" W 81° 45' 16.2".

CWA Section 316(b) Supporting Information Vogtle Electric Generating Plant Units 1 & 2 The maximum design flow rate from the Savannah River for VEGP Units 1&2 is approximately 88,000 gpm (22,000 gpm per pump). Typically, only one to two makeup pumps are operating at any given time, resulting in a general intake flow rate of about 44,000 gpm, or about 64 MGD.

VEPG Units 1&2 is used as a base load electric generating facility and are designed to operate year-round . The units are operated with a maximum capacity factor of about 93 percent (annualized), considering scheduled outages and other plant maintenance. Accordingly, the cooling water intake structure is projected to operate 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months a day, 365 days a year without any seasonal variation.

The applicant need only identify those species not already identified as fragile at 40 CFR 125.92(m);

No species have been identified at VEGP Units 1& 2 in addition to those listed in 40 CFR 125.92(m).

(xii) For the owner or operator of an existing facility that has obtained incidental take exemption or authorization for its cooling water intake structure(s) from the U.S. Fish and Wildlife Service or the National Marine Fisheries Services. any information submitted in order to obtain that exemption or authorization may be used to satisfy the permit application information requirement of paragraph 40 CFR 125. 95(0 if included in the application.

No incidental take exemption or authorization has been requested or obtained for VEGP Units 1 &

2, and therefore, this section does not apply.

40 CFR 122.21(r)(6)- Chosen Method(s) of Compliance with Impingement Mortality Standard The owner or operator of the facility must identify the chosen compliance method for the entire facility; alternatively, the applicant must identify the chosen compliance method for each cooling water intake structure at its facility.

The chosen method of compliance with the impingement mortality standard is the closed-cycle cooling option, as defined at 40 CFR 125.92.

VEGP Units 1 &2 currently utilizes a closed-cycle cooling system for each unit. Each unit's cooling tower is a hyperbolic natural draft structure with a design circulating water flow rate through the tower of 509,600 gallons per minute (gpm). The cooling tower basin has a storage volume of 6.0 x 106 gal of water. The cooling towers utilize natural convection to remove heat added by cooling the condenser from the water as it falls through the fill material located in the tower. The water falls to the basin beneath the tower and, in the process, gives up some of its heat to the atmosphere.

1. INTRODUCTION In February of 2008, Georgia Power Company's (GPC) Environmental Services staff based in Smyrna, Georgia responded to Southern Nuclear' s request to conduct an aquatic impingement and entrainment assessment of Plant Vogtle's make-up water intake structure. Following a site reconnaissance in early March 2008, GPC submitted a plan of study The sampling approach included four primary components including:

I) source water ichthyoplankton sampling in the Savannah River,

2) source water/intake canal ichthyoplankton (entrainment) sampling,

3) impingement sampling via the traveling screen screen-wash system, and

4) performance of work under a quality assurance/quality control plan to ensure that work was performed in high quality manner consistent with standard scientific practices, and as it pertains to sampling methodology, perform a comparison between collection gear types and data between two sampling locations upstream of the intake structure.

Following a brief period of internal review by Southern Nuclear, a sampling plan was established with authorization to proceed including implementations by Plant Vogtle to install temporary procedure modifications in order to provide GPC staff site access to aquatic impingement and entrainment sampling. Plant Vogtle Operations personnel have provided and continue to provide communications and staff resources to operate the traveling screen system for the ongoing impingement study component.

Field components of the study were initiated on I 0 March 2008. Study components 1, 2, and 4 described above have been completed for the entrainment portion of the study. The methods and results of those study components are described in the following section of this report. Study component 3, the impingement study, was designed as a 12-month study encompassing twice per month sampling currently scheduled to conclude in February 2009. Interim impingement data have reported in a separate report (GPC 2008).

Under direction and support provided by Southern Nuclear, the study approach, field sampling components, and data analysis of this study have been conducted and managed by Georgia Power Company's Environmental Services Group based at 5131 Maner Road in Smyrna, GA LAB 7600 5

Field methods used in this study are based on widely accepted, standard scientific practices and stem from Georgia Power Company staffs' previous experience in performing entrainment and impingement assessment studies following applicable EPA guidance.

Planning elements for this study include:

);> review of historical and recent studies characterizing the fish community in the vicinity of the site and potential fish community impacts via Plant Vogtle Operations

);> a sampling approach to support development of a scientifically valid estimate of entrainment rate at Plant Vogtle

);> an assessment of a fish communities susceptible to entrainment in the vicinity of the make-up water intake structure to include:

);> taxonomic identification of entrained fish species and their life stages to the lowest practical taxon

2. STUDY AREA DESCRIPTION 2.1 Environment The Plant Vogtle Site is located at Savannah River Mile (RM) 150.9. The plant is located approximately 26 miles south-southeast of Augusta, in Burke County, Georgia (Figure 2-1) directly across the river from the Department of Energy's Savannah River Site (SRS) property. The Savannah River, which provides the make-up-cooling water source for Plant Vogtle's cooling tower system, is a primary river that drains the eastern and western boundaries of Georgia and South Carolina, respectively. The Savannah River originates in the mountains of North Carolina, South Carolina, and Georgia and flows approximately 505 kilometers (km) to the Atlantic Ocean. The Savannah River in the vicinity of Plant Vogtle lies in the Coastal Plain physiographic province which is characterized by sandy or sandy loam soils with rolling hills and a mixed pine-hardwood vegetative association. The Savannah River upstream from the Plant Vogtle intake structure receives wastewater discharges from municipalities and industries. The river at the site is typical of large southeastern Coastal Plain rivers except that the channel was historically dredged and maintained by the Corps of Engineers (COE) so that it is highly channelized. Studies on the Savannah River have been conducted since 1951 (GPC. 1984b). In a recent publication by Marcy et al. 2005, Fishes ofthe Middle Savannah River Basin, the Savannah River was characterized as being high in fish diversity and home to at least 118 native fish species. The middle Savannah River in the vicinity of Plant Vogtle is home to at least 98 species of fish - fifteen of which are species introduced mostly for fisheries management purposes. Potential aquatic community entrainment at Plant Vogtle was initially characterized in early siting studies of the mid-1970s and reported later in GPC's 1984 Operations Environmental Report for licensing of Plant Vogtle (GPC 1984).

The 1984 report of site studies performed during January through August of 1974 suggested that prevailing biological and physical factors combined with the low intake canal velocities, would result in minimal entrainment of eggs and larvae and not have a significant effect on the fish population of the Savannah River.

2.2 Intake Canal and Structure Among its major components, the Plant Vogtle river water intake system consists ofthe intake canal structure and make-up pumps. The intake canal is 356 feet (ft) long, 140 ft wide with an earthen bottom at 67 ft above mean sea level (msl), at the time it was constructed, and vertical steel sheet pile sides (canal walls) extending to 98 ft msl.

The intake canal has a surface skimmer weir at about 78 ft msl with guide vanes at the river entrance. The skimmer weir consists of fixed and removable sections with the fixed sections having elevations less than 78 ft msl. A bottom canal weir is located approximately 100 ft from the mouth of the canal. Silting protection is provided by a sedimentation basin formed by the skimming weir and the canal weir. A floating trash boom is located in front of the skimmer weir to divert large floating debris (GPC 1984).

The component of river velocity parallel to the canal opening is small thus minimizing the potential for fish entering the canal. In addition, a lateral passageway is provided at the canal entrance which permits fish to escape (GPC 1984).

Flow through the intake canal is determined by plant operating conditions. Water velocities in the canal are also dependent on the river water level. Average velocity at the river intake canal ranges from 0.01 ft/second (s) at minimum plant withdrawal rate of 13,000 gallons per minute (gpm) and a river water level of 98 msl (top of the canal sheet pilings) to a 1.05 ft/s at a maximum plant withdrawal rate (72,000 gpm) based on all four make-up water pumps running and a minimum river water level of 78.4 ft msl (allowing for a 2 ft degradation of river bed elevation) at a flow of 5,800 cubic ft/s (ft 3/s). At average plant operating conditions (42,000 gpm with two intake makeup water pumps operating) and annual water level (84 ft msl based on average river flow of I 0,300 ft 3/s, the canal entrance velocity is 0.11 ft/s (GPC 1984).

The intake structure is a 14 7 ft long, 72 ft wide concrete structure with four chambers, each housing one pump, a traveling water screen, a trash rack, stop logs, and screen wash discharge to a common pit with course-grated steel insert basket. The traveling screens are FMC type-45A (3/8 -inch size steel mesh of ASTM A36 structural steel shape) that currently are set to rotate one cycle every eight hours (hrs) or on a high screen differential of six inches of water at the low-setting rotation speed of five ft per minute (min). The velocities of water through the traveling screens at average annual water level (84.0 ft msl) is 0.69 ft/s and 0.82 ft/s with river level at minimum stage (78.4 ft msl) (GPC 1984).

LAB7600 9

2.3 Make-up Water Pumps Four vertical pumps, each name-plate-rated at 22,000 gpm (or a maximum pump flow of 15.84 million gallons per day [MOD]) are located in the river intake structure.

The typical operating scenario utilizes two pumps. Total pumping rates can vary day to day based on operational needs. Pumping rates vary periodically due to make-up water needs based on cooling basin water levels. Also, periodically, cooling tower blow-down requires added dilution which requires increased pumping volumes for discharge compliance.

3. METHODS Copies of template field data sheets used for sampling source water and entrainment are included in Appendix A.

3.1 Source Water Early Life Stage Fish Community Assessment Ichthyoplankton (fish eggs and larva) samples were collected from the Savannah River near the Plant Vogtle make-up water intake structure as a means to characterize the component of the fish community most subject to entrainment. Field sampling began during the late winter/early spring of 2008 in order to capture a representative sample of early season migratory fish spawning. Source water community samples were collected twice per month (approximately at two-week intervals) during 10 March 2008 through 29 July 2008. The sampled period is typically representative of maximum spring and summer fish egg and larval drift- the most biologically productive season of the year for spawning resident and migratory fishes.

Each sample event consisted of an ichthyoplankton collection at approximately 6-hour (hr) intervals. Samples from each discrete station along across-sectional transect were composited - ultimately resulting in collection of samples representative of 12-hour diurnal (daytime) and 12-hr nocturnal (nighttime) periods to facilitate assessment of die I behavior in the drift community potentially subject to entrainment into the Plant Vogtle make-up water intake structure.

Ichthyoplankton samples were collected from one primary location, a cross-sectional transect, positioned approximately at RM 151.0 (at inland waterway marker No. 72) or about 300 ft upstream from the mouth of the intake canal. Additionally, samples were periodically collected from a second transect located about 0.3 miles farther upstream in a reach of the river in the vicinity of the area proposed as the new make-up water intake for Units 3&4 (Figure 2-l ). Three discrete ichthyoplankton stations were positioned along transects approximately 30-ft from the left bank, at mid-channel, and approximately 30 ft from the right bank. Ichthyoplankton samples were collected at the upstream location in the same left-, mid-, and right-bank positioning manner for an examination of between-gear and between-location analysis.

Samples collected from the second location (near the proposed Unit 3&4 intake) were used for analysis and comparison between gear types and efficiencies (e.g.,

LAB7600 11

plankton net vs. submersible pump) and locations (Savannah River main stem vs. inside the intake canal) in the source water and entrainment sampling locations.

Ichthyoplankton samples were collected at each station with a standard double plankton net rig comprised of a towing bridle, two 500-micron sized Nitex mesh 3: I ratio (length to diameter) nets mounted in a side by side 0.5 meter round net ring bracket. Each net captures samples with a plastic "sieve bucket" mounted at the cod end. A portion of the bucket has an opening screened with 500-micron stainless steel mesh wire to retain planktonic organisms.

The double net rig yielded a field sample and a replicate sample set aside for archival as a I: I fallback quality assurance measure. Field samples were submitted for laboratory taxonomic processing and the archived samples stored at Georgia Power Company's biology lab in Smyrna, GA. The net hoop/bracket was equipped with an 11 lb. wire depressor weight (Wildco Model 90-G I 0) to minimize tangential drag behind the boat as a result of river current/water column velocity. An additional 16 lbs of weight in the form of down-rigger "cannonball" weights" were also used to further increase slope and reduce the length of cable required to sample at desired depth intervals. A calibrated, propeller driven General Oceanics current meter (Model No.

2030R) was mounted in the mouth of one of the two nets to provide for calculation of sampled water volumes and velocity for each discrete sample.

Before deploying the plankton nets, the sample boat was positioned at a given sampling station by setting an anchor. Once anchored, the net rig was deployed into the river by means of a hoist, winch, and depth-marked-cable. Prior to deployment, the current meter start count was recorded on a field data sheet. Actual sampling depth during each event was determined prior to deployment based on maximum water depth.

The sampling method was based on adequately sampling the entire water column to yield a representative community sample by capturing both floating and demersal early life stages of fish in the drift community. Based on depth sounder readings on the boat depth finder (Garmin MapSounder 168), the net rig was initially deployed to the deepest optimal sampling depth (as a means to limit substrate materials from entering the sample) then retrieved by !-meter sampling intervals following five to ten-minute sampling effort at each depth interval. For example, if depths could be effectively sampled down to four meters based on river stage, the total sample time would be 20 minutes based on 5-minute sampling effort at all depth intervals. As river stage declined from spring into summer, sampling times were increased with each event to offset the reduced number of depth intervals and otherwise reduced sampling effort/volume. In LAB7600 12

that the goal of the study was to provide representative drift community samples by sampling at least between 100 to 150 cubic meters (m3) of river water per net per station.

Following the sampling effort at each station, the net rig was retrieved via hoist and winch. As the nets breeched the water surface upon retrieval, the current meter end-number was read from the current meter and recorded on the station data sheet. The plankton nets, partially suspended at the water surface were manually washed down from the outside with river water to rinse down and capture any sample debris and/or organisms clinging to the upper walls of the nets. Once rinsed, the nets were brought onboard and the sample buckets removed from each net by loosening stainless steel attachment bands. Bucket screens were back-washed with river water with a hand held squirt bottle. Once rinsed, the nets were brought onboard and the sample buckets removed from each net by loosening stainless steel attachment bands. Bucket screens were back-washed with river water with a hand held squirt bottle.

Sample materials were then dispensed from each net bucket into separately labeled 1-liter wide mouth plastic jars. Contents of each jar were fixed and preserved with 5-percent formalin. Label information was placed inside the jar with the sample and included the site name, station location, date and time of collection, indication of field sample vs archive sample, and collectors' initials. The jars were temporarily stored in coolers or an open organizer tray for transport under chain of custody to Georgia Power Company's biology lab located at 5131 Maner Road in Smyrna, GA. Once retrieved and signed for acceptance at the lab, sample jars destined for the processing lab (Normandeau Associates Laboratory, 25 Nashua Road, Bedford, New Hampshire) were assigned outer stick-on labels to match an inner jar label. Jar lids were taped, and the jars each double bagged in zip-lock bags before being packed into a cooler with a completed chain-of-custody form taped into the lid of each cooler. The back page carbon copy of each completed chain of custody form was retained by the task manager before sealing the shipping containers. Additional packing material was added before each cooler was securely taped and shut and labeled for overnight shipment (FEDEX) to the processing lab.

In addition to the sampling station identifiers, sample collectors, sample depths, sample times, and current meter readings, other supporting field data collection information was recorded on field data sheets. These data included measures of physicochemical water quality including pH (standard units), surface water temperature CCC), turbidity (NTU), conductivity (microSiemens/cm), and dissolved oxygen LAB7600 13

concentration (mg/L). Additionally, any observations regarding current weather, recent precipitation, equipment malfunction, or deviations from the intended sampling method were noted on field data sheets.

Following each sample event, provisional river discharge data corresponding to the days and nights of sampling dates was electronically retrieved from the USGS real-time data website for the Waynesboro, GA gage Station No. 021973269 (located at Plant Vogtle) and stored on Georgia Power Company's network computer system.

Samples received by the taxonomic processing laboratory were rinsed and sorted to remove any preserved fish eggs and larvae from detritus or other sample debris. Each egg and larva were identified to the lowest practical taxon and enumerated before a final quality assurance check and data entry. Lab results were submitted to Georgia Power in electronic form once the samples were fully processed. The lab data were further managed at Georgia Power in electronic spreadsheets for synthesis into this report.

3.1.1 Calculation of Source Water Sample Egg and Larval Densities Densities were calculated by dividing the total number of eggs and larvae for a given sample period by the total volume of river water filtered through the plankton net.

The densities were further examined by performing the same calculation separately for eggs and larvae.

3.2 Entrainment Assessment The first of nine of entrainment sampling events was conducted 26 March 2008.

This sample was collected in the mouth of the intake canal by means of a boat-mounted 425 gallons per minute (gpm) centrifugal pump. This event provided an opportunity to evaluate and validate pumping as a collection method for entrainment sampling. The boat-mounted pump collected entrainment samples by moving water through the pump through a 500 u mesh ichthyoplankton net mounted at the boat railing. During the same sampling event, source water samples were collected with the same net gear in the stationary, boat drift net sampling method described above. Both pumped- and netted samples yielded at least two life stages of fish larvae from multiple species in densities per species ranging from 0.004 to 0.03 fish per m3 for pumped samples and 0.00 I to 0.05 fish per m3 for net samples thus validating the use of pumping as a method for collection of entrainment/canal samples. Samples were confirmed by the taxonomic LAB7600 14

laboratory as being captured and preserved in good condition. This evaluation, and ultimately, change in sampling gear was made after the first event following investigator observations that sampling from the inner canal location and in the relatively uniform and quiescent hydraulic characteristics inside the canal would yield a more representative sample of the entrained community. Also, due to the canal configuration with two tiers of sheet piling, it was not feasible to sample further inside the canal with the boat mounted pump. Instead, the more portable dual submersible pump system was chosen for use at a deployment/sampling point located inside the canal closer to the intake screens. The submersible pump system was shore-based, powered by a portable electric generator, and positioned on the top of the south canal bulkhead about 150 ft upstream from the intake screens (Figure 2-1 ). The following eight entrainment sampling events were conducted using the submersible pump system.

Entrainment samples were collected twice per month (approximately at the same two-week intervals as riverine source water community samples) beginning on 26 March 2008 and ending on 29 July 2008. Each sample event consisted of approximately 6-hr sample collection time intervals which were ultimately composited to be representative of 12-hr diurnal and 12-hr nocturnal periods. This sample schedule provided a means to perform a direct comparison to the riverine drift community beyond the mouth of the canal.

The entrainment pump system consisted of two Tsurumi Model LB3-750 submersible pumps each with name plate capacity at level head of 73 gpm. This type of pump is capable of pushing water vertically through a two-inch hose as high a 37 ft.

The height of the canal wall from water surface to top of the wire rope hand railing during the survey ranged from approximately 23 to 24 ft. The distance from the water to the head of each net mouth was monitored during the study in order to calculate entrainment sample volume based on manufacturer curve rated head loss from maximum rated pump capacity at height. Canal water (entrainment samples) delivered by pump ultimately emptied through horizontal sections of hose into the same type of standard double plankton net rig mounted inside two side by side 55-gallon (gal) plastic drums located at the top of the canal wall. Each drum discharged sieved sample water through a two-inch diameter PVC drain fittings (45 degree elbows) which in turn emptied into a four-inch corrugated plastic storm drain hose ultimate carrying sieved water back into the canal at a location positioned about 20 ft downstream of the submersible pumps. The sampling goal was to collect between 50 to 100 m 3 of sample per net. Sample volume was calculated by multiplying head-rated pump capacity times the time (minutes) pumped then converted from units of gpm to m 3* Just as with the LAB7600 15

source water sampling, the double net rig was used to yield simultaneous field and replicate samples for archival during each event as a fallback quality assurance measure, if needed. Entrainment samples were collected from sieve buckets then handled and shipped in the same manner as the riverine source sampling. Any observations regarding equipment malfunction or deviations from the intended sampling method were noted on field data sheets.

3.2.1 Calculation of Entrainment Sample Densities Community (fish eggs and larvae) densities were calculated by dividing the total number of eggs and larvae for a given sample period by the total volume of river water filtered through the plankton net and the result reported in number of organisms per 1OOO-m 3 (1 000 cubic meters) 3.2.2 Calculation of Entrainment Rate The entrainment rate was developed based on actual daily make-up water intake pumping. In that diminished occurrence of source water fish eggs and larvae at the end of July clearly bracketed the end of the drift season, the five-month entrainment study result represents the annual entrainment estimate. To calculate the annual estimate, daily entrainment rate (number of organisms/1 OOO-m3) was established based on the result of each half-monthly entrainment sampling event result. Daily entrainment rates based on entrainment sample volumes were scaled-up by the appropriate multiplier to reflect actual daily make up water intake volumes. These adjusted daily entrainment rates were then summed to yield half-monthly entrainment rates. Half-monthly entrainment rates were summed to yield an unadjusted annual rate.

Additionally, for perspective and to account for expected natural and operational variability, a half monthly mean entrainment rate was calculated for all sampling events and statistically treated with the 95-percent confident interval. The upper limit was applied to the half-monthly mean entrainment rate which was in turn multiplied out by a factor of five in order to yield an upper estimate of "annual" entrainment for Plant Vogtle based on the upper 95% confidence limit.

3.3 Quality Assurance and Quality Control Project quality assurance/quality control (QA/QC) procedures for this study followed established procedures for general field and laboratory studies conducted by Georgia Power's Environmental Laboratory (GPC, 2002). Each sampling event LAB7600 16

included senior technical involvement and preparation of trip reports summarizing field observations on the performance of the collection system including the sample collection, handling, processing, record keeping, any health and safety issues on site and communication with plant personnel.

3.4 Plant Operations and Environmental Parameters Plant operational parameters were recorded at Plant Vogtle throughout the course of the study including intake make-up water flow rates and ambient and/or inlet water temperature. Environmental parameters such as river stage data and precipitation data were obtained from electronic sources. Appendix B contains tabular and/or graphical summaries of these supporting data.

3.4.1 Plant Operations The frequency of power generation, thus make-up cooling water, pump flows, at Plant Vogtle is very stable. Although, each of the four make-up water intake pumps at Plant Vogtle are design-rated to pump 22,000 gpm (63.36 mgd or 240,000 m 3/day),

actual pump flows through a given period of time can be affected by daily operational needs, periodic maintenance (outage), and to a minor degree, changes inflow head pressure due to fluctuations in river stage elevation. A summary of mean pumping rate per half monthly sampling period is as recorded during the study period is shown in Table B-1, Appendix B.

3.4.2 Environmental Parameters Table B-2 in Appendix B provides a summary of water quality parameters recorded during the source water study component. Water temperature data were collected through a variety of means during the study including manually recorded ambient river surface water temperatures via a multi-array Hydrolab water quality meter, and for the purpose of trend analysis electronic USGS daily water quality data records as available and applicable for the study area.

The river stage at Plant Vogtle change constantly in response to regulated flow conditions from Corps of Engineers operations upstream and influenced by local precipitation and/or riparian vegetation evapo-transpiration rates. Regional ambient air temperatures, river stage and discharge, and precipitation records were electronically obtained from the USGS Waynesboro gage (Station No. 021973269) and the University of Georgia weather monitoring net work (Figures B-1 through B-3; Appendix B).

4. RESULTS 4.1 Source Water (Savannah River) Early Life Stage Fish Community A total of 67 source water ichthyoplankton samples were collected from the Savannah River during the study period. Sixty (89.5 percent) of those samples were collected from the three sampling stations positioned along the primary sampling transect located upstream from the intake structure at its confluence with the Savannah River. The seven (11.7 percent) remaining samples, used as a measure of be!ween-gear and between-location analyses, were collected along the second transect located near the proposed location of the Units 3&4 intake structure (Figure 2-1 ).

4.1.1 Species Composition and Relative Abundance Table 4-1 provides a list of taxa and taxa groups (fish eggs and larvae identifiable in the lab to the lowest practical taxon) collected from the source water community.

Sixteen species were identified among 23 taxa groups representing 13 taxonomic families (Table 4-1 ). Among the seven remaining taxa groups, four were identifiable to Family-level, two groups to Genus-level, and one to Class-level. No protected species were collected from source water. All species or taxa groups except for yellow perch (Perea flavescens), an introduced species, and carp (Cyprinus carpio), an exotic species, are considered native to the drainage.

A total of 910 fish eggs and larvae were collected from source water samples (Table C-1; Appendix C). The single numerically most dominant taxa group was Unidentified Cyprinidae (minnows) with 184 specimens accounting for 20.2 percent of the total sample followed in decreasing order by American shad (Alosa sapidisimma) with 166 individual specimens (18.2 percent) and Unidentified Clupeidae (herrings)

(165 specimens or 18.1 percent).

Among the total source water sample, at least nine species represented by 18 specimens in three life stages (eggs, yolk-sac and post-yolk-sac larvae) were collected in a total of four daytime samples (-1.9 percent of the total source water sample) collected near the proposed location for Units 3&4. Species or taxa groups represented there included brook silverside, carp, northern hogsucker, spotted sucker, yellow perch, and unidentified members of Clupeidae, Cyprinidae, Unidentified darters, and the Class Osteichthyes. Unidentified darter was the most abundant taxon (Table C-2, Appendix C).

4.1.2 Temporal and Diel Distribution The relative variation in egg and larval sample abundance during the five months of survey varied from about two percent (early March and both July sample events) to almost 19 percent (late April into early May)(Table C-1, Appendix C). Peak organism abundance was observed from 23 April to 8 May 2008. Peak fish egg and larval abundance in riverine drift was marked primarily by relatively high numbers of egg, yolk-sac and post-yolk-sac life stages of Unidentified Cyprinidae, American shad, and Unidentified Clupeidae. The number of individual specimens per sampling event ranged from 0 to 170 with an average of 46 organisms per sampling event.

As shown in Figure 4-1, egg and larval drift abundance during the study period declined with elevated springtime river flows ranging upward near 13,000 cfs to a late-through summer low-flow average near 4,100 cfs. A sharp decline in egg and larval density was observed in mid-May which continued to an end-of-season bracket by mid July. Thus the opportunity for intake entrainment at Plant Vogtle is reduced with declining seasonal river flows. This trend is typical of southeastern, seasonal drift patterns in Piedmont and upper Coastal Plain systems.

As for die! effect, approximately 61.6 percent of all organisms collected were found in nighttime samples. The number of organisms was higher in night samples in 9 of 10 sample events. Night samples averaged 56.1 organisms per sample event whereas day samples averaged 34.9 organisms per sample event.

4.1.3 Life Stages As shown in Table C-3, Appendix C, peak drift in the Savannah River occurred in early May and with this peak node of egg and larval abundance bracketed between early April and mid-May. The most abundant life stage collected in source water samples was fish eggs which comprised 562 (61.8 percent) of the total 910 specimens collected.

Peak drift for eggs occurred during late April through early May 2008. Yolk-sac larvae and post-yolk-sac larvae comprised 16.4 and 16.2 percent of the source water community sample, respectively. Peak drift of yolk-sac larvae and post-yolk-sac larvae occurred during late April and early may, respectively. Yearling or older life stages in the samples were few in number comprising 4.4 percent of the sample {Table C-3 ,

Appendix C). Peak abundance for yearling or older life stages occurred during early June through mid-July.

c 2,000 Study Period Note: Savannah River egg and larval densities are presented as half-monthly steps as calculated from actual sampling events during the study period.

The most abundant taxa group, Unidentified Cyprinidae (minnows), exhibited four life stages in source water samples with the most abundant life stage occurring as yolk-sac larvae observable in peak proportions during late April and again in the month of June (Table C-5, Appendix C). This peak of yolk-sac larvae were followed by an earlier pulse of eggs in the drift in late April.

American shad, a migratory (anadromous) species, was the second most abundant drift organism collected from the Savannah River. American shad was encountered in two life stage forms including egg (165 specimens) and yolk-sac larvae (one specimen).

The bulk of egg and larval drift for American shad occurred primarily during mid-April through May with peak abundance noted in early May (Table C-5, Appendix D).

Unidentified Clupeidae, the third most abundant taxa group collected from source water was observed in three life stages including egg, yolk-sac larvae, and post-yolk-sac larvae. Egg life stage was the most abundant with peak occurrence in the drift between early April and mid-May (Table C-5, Appendix C).

4.1.4 Source Water Community Density Table C-4, Appendix C shows a summary of egg and larval density as collected in the riverine source ichthyoplankton samples. The summary provides density as number of specimens per 1000 m3.by sampling date and by day and night sampling periods.

Average daytime egg and larval density per sampling event varied from 7.8 organisms/1 000 m 3 (late July) to approximately 659.1 organisms/ I 000 m3 (late April) with an overall daytime mean of 19.2 organisms/1 000 m3 Nighttime densities varied from 21 organisms/1000 m3 (early March) to approximately 1999.7 organisms/1000 m3 (early May) with an overall mean per sampling event mean of33.5 organisms/1000 m3

For the entire study period, mean, per-event egg and larval density was 403.6 organisms/1000 m3

The Unidentified Cyprinidae yielded the highest day-time density for a single taxa group at 289.4 organisms/ I 000 m 3 American shad were observed in the highest density for nighttime samples as well as overall for any single species or event throughout the study period.

For the sake of comparison, source water samples were collected during the daytime near the proposed location of Units 3&4 during the two sampling dates of late May and early June resulting in a mean fish egg and larva density of 52.9 organisms/1000 m3

Unidentified darters yielded the highest density (17.7 LAB7600 20

organisms/}000 m3) among samples collected at the upstream location. During the same time as those sampling events, daytime egg and larval densities sampled at the primary transect were very comparable ranging from 29.5 to 52.8 organisms per I OOO-m3 (Table C-4, Appendix C). No one species was unique to the proposed intake location of Units 3&4.

Based on the USGS gage data, mean daily river flow during the five-month study period (156 bracketed days), was 11,403,000 m3 (- 11.4 million cubic meters) Source water organism density was 403.6 organisms per I OOO-m 3 (Table C-4, Appendix C).

4.2 Entrainment A total of 36 ichthyoplankton samples collected inside the intake canal (Figure 2-1) during the study period. Due to the apparent uniform and quiescent hydraulic conditions inside the intake canal, it was assumed that single point mid-depth location provided representative samples of the entrained community. Once com posited into 12-hr day and 12-hr night samples, following 6-hour sample collection intervals during each period, the 18 samples were processed for taxa identification and enumeration.

4.2.1 Species Composition and Relative Abundance As shown in Table 4-1 and Table D-1, Appendix D, a total of 25 individual specimens comprised of three fish species and four taxonomic families/groups were collected via pumped entrainment samples during March through July 2008. No protected species were collected.

Among the three species, yellow perch (Perea jlavescens) was the most abundant (40 percent) followed in decreasing order of ranked abundance by yellow bullhead (Ameiurus nata/is) and pirate perch (Aphredoderus sayanus), each accounting for four percent of the sample catch. As for the unidentified taxa, members of the Catostomidae (suckers) were thee most dominant (20 percent) followed by the Centrarchidae (sunfishes) with 16 percent ofthe sample (Table D-1 Appendix D).

4.2.2 Temporal and Diel Distribution As shown in Table D-1, Appendix D, relative change in sample abundance was quite variable (0 to 52 percent) during the 5-month study. Fifty-two percent of the entrainment sample organisms were collected in the month of March, 20 percent in April and 16 percent in the month of July.

LAB7600 21

The majority of entrainment sample organisms were collected at night (72 percent) vs. day (28 percent) (Table D-1, Appendix D).

4.2.3 Life Stages Table D-2, Appendix D provides a breakdown of life stage occurrence by sample dates for taxa collected in entrainment samples. The few egg and larval specimens collected in entrainment samples occurred between mid-March and late-July with peak abundance (52 percent of samples) observed in mid-March. The most relatively abundant life stage component of entrainment samples was post-yolk-sac larvae representing 68 percent of the samples. Yolk-sac larvae was the second most abundant life stage group represented in entrainment samples accounting for 24 percent of the total. No eggs were encountered in entrainment samples indicating their potential absence in entrained water due to early settling out of the water column between the mouth of the canal and the head of the intake structure.

The most abundant entrainment sample species was yellow perch which was encountered as being equally represented in two life stages (yolk-sac and post-yolk-sac larvae)(Table D-3; Appendix D). Yellow perch were collected from mid-march to late April in entrainment samples.

Five unidentified, individual specimens of Catostomidae (suckers) were the second most abundant group represented in entrainment samples. Catostomids were encountered only in post-yolk-sac larval form and from mid-March to late April Unidentified Lepomids (sunfishes), the third most abundant taxa group collected in entrainment samples, were represented by four specimens distributed in two life stages including yolk-sac and post-yolk-sac larvae. Unidentified Lepomids were collected from mid-June through late-July (Table D-3, Appendix D).

4.2.4 Entrainment Rate Table D-4, Appendix D shows a tabular summary of egg and larval density as collected in the entrainment sampling program. The summary provides density as number of specimens by 1000 m3.by sampling date and by day and night sampling periods. Per sampling-event daytime egg and larval density varied from 0 (zero) organisms/ ! 000 m3 to approximately 18.1 organisms/ ! 000 m3 (late March). Nighttime LAB7600 22

density varied from 0.01 to 29 organisms/ 1000 m 3 For the entire study period, mean per-event density was approximately 11 .3 organisms/] 000 m 3 .

Table D-5, Appendix D, provides a summary of actual sample entrainment compared to the annual estimate and the annual estimate derived by applying the 95%

upper confidence limit (UCL) to the half-monthly mean. The actual number of organisms enumerated in entrainment samples is 25. The annual estimate based on the sum of half monthly totals is 448,803. No organisms were collected in two of nine entrainment sampling events resulting a half-monthly mean entrainment rate of 49,867.

Source water samples did not reveal a correlating trend at the time (May samples).

When applying the 95% UCL, the statistical effect on the mean half monthly entrainment value results in a lower annual entrainment rate (568, 154 organisms including the calculated confidence level of 13,261 organisms).

Plant Vogtle's mean daily make-up water intake pumping flow (241,000 m 3) represents approximately 2.1 percent of the mean daily flow (II ,402,000 m 3) in the Savannah River (at Plant Vogtle based on study period flow records). Estimated daily entrainment rate is I ,230 organisms [eggs and larvae]) whereas the estimated daily source water drift abundance is 312,039 organisms (Table D-5, Appendix D).

4.3 Operational and Environmental Parameters 4.4.1 Operational Parameters Plant Vogtle conducted make-up water pumping through its intake structure throughout the entire study period. Copies of operational reports showing daily recorded make-up water pumping are included in Appendix B. Mean daily make-up water pumping rate for the entire 156-day study period was 64.3 mgd (or 243.400 m\

Compared to the mean daily discharge for the Savannah River of II ,402,000 m 3* make-up water up pumping at Plant Vogtle represents approximately 2.1 percent of the available Savannah River flow based on measurements recorded during March 2008 -

August 2008.

4.4.2 Environmental Parameters Water quality data were recorded by the field crew during each field sampling events (March 2009 - August 2008)(Table B-2, Appendix B). Surface water temperature ranged from 12.3 to 28.6°C). The pH (standard units) varied from 6.7 to LAB7600 23

8.4. Specific conductance ranged from I 03.4 to 140.1 uS/em with the highest measurements recorded at the end of the sampling period. Dissolved oxygen ranged from 6.7 to 9.0 mg/L consistent with inverse response to increasing water temperature.

Turbidity ranged from 0 to 6.4 NTUs varying with precipitation.

Regional air temperature ranged from 1.0 to 38.1 oc based on the Midville, Georgia weather monitoring station (Figure B-1, Appendix B). River stage ranged from 5.9 to 11.7 ft (USGS Waynesboro Gage Station) with a daily mean stage of 6.8 ft.

River flow ranged from 3, 760 to I 0,500 cfs with a daily mean flow of 4,646 cfs (or II ,367,000 m3). River stage exhibited decline consistent with seasonal trend from early spring to late summer (Figure B-2, Appendix B). Daily precipitation throughout the study period ranged from 0 to 2.0 inches with mean daily rainfall of 0.09 inches (Figure B-3, Appendix B) which is characteristic of severe drought conditions for the second consecutive year in the region.

Daily entrainment rates were statistically compared through regression analysis with daily data for these environmental variables. No significant correlation relationship was found between air temperature, water temperature, precipitation, or river stage for entrainment rate.

SUMMARY

AND DISCUSSION An entrainment study of Plant Vogtle's make-up water intake structure was conducted by GPC environmental field services staff during March through July of 2008. The study included two primary tasks including:

~ source water (riverine) sampling for fish eggs and larvae from the Savannah River upstream of the Plant Vogtle intake canal, and

~ entrainment sampling for fish eggs and larvae from the Plant Vogtle intake canal for fish eggs and larvae.

Results of the source water and entrained community descriptions are based on five months of"half-monthly" sampling during March through July 2008.

Entrainment sampling yielded seven species or taxa groups (29.2 percent) out of the 24 taxa groups represented in source water samples. Entrained taxa were also represented in the list of source water taxa. No protected fish species were encountered in source water or entrainment samples.

LAB7600 24

Peak organism abundance in the Savannah River occurred from 23 April to 8 May 2008 and was marked by relatively high numbers of egg, yolk-sac and post-yolk-sac life stages of Unidentified Cyprinidae and American shad. Source water samples yielded at least 23 species representing 13 taxonomic families. Most (-61.6 percent) of the eggs and larvae were present in nighttime samples. Eggs were the most abundant life stage collected overall accounting for 61.8 percent of the total sample. The density of source water organisms was calculated at 403.6 organisms per 1000 m 3 . Extrapolation of sample data results in a calculated source water drift rate of approximately 312,039 organisms per day.

Total entrainment sampling effort yielded 25 individual specimens representing at least seven species indicating a paucity of organisms present in canal intake waters.

Most (72 percent) life stage forms in entrainment samples were post-yolk-sac larvae.

No eggs were encountered in entrainment samples an indication that eggs may have settled out of the water column as water velocities substantially diminish at the mouth of the canal. Most organisms were collected at night. The density of entrained organisms was calculated as 11.3 organisms per 1000 m3 based on sample results.

Annualized extrapolation of sample data resulted in an entrainment rate of 1,230 organisms (eggs and larvae)/day.

Plant Vogtle's mean daily make-up water intake pumping flow of 241,000 m 3 represents approximately 2.1 percent of the mean daily flow 11,402,000 m3 in the Savannah River based on study period flow records. No statistically significant relationship was found between entrainment rate and trends of air temperature, water temperature, or river discharge. Empirical observations of river flow and riverine egg and larval drift during the study period (Figure 4-1) clearly demonstrated abrupt decline in drift abundance following the end of elevated springtime flows and the beginning of early summer flow norm.

Fish eggs and larvae source water samples were approximately 36.4 times more numerous than entrainment samples collected during the same period. The three most abundant source water taxa were not ranked the same as found in entrainment samples.

The numerically most dominant source water taxa were Unidentified Cyprinidae (20.2 percent), American shad (18.2 percent), and Unidentified Clupeidae (18.1 percent);

whereas, the most abundant entrainment sample taxa were yellow perch (40 percent),

Unidentified Catostomidae (20 percent), and Unidentified Lepomis (16 percent). By comparison, yellow perch accounted for 1.8 percent of source water samples, LAB7600 25

Unidentified Catostomidae (8.2 percent), and Unidentified Lepomis (2.3 percent) ofthe source water sample.

Pirate perch was the only species common to source water and entrainment samples. Although not the most common species among either source water or entrainment samples, pirate perch is known to be common in the study area and is well suited for habitation and spawning in a variety of habitat types including the intake canal. Pirate perch is known both as an egg broadcaster over a variety of substrates as well as being a cavity nester (Marcy et al. 2005).

Six other species or taxa groups were represented both in source water and canal entrainment samples (Table 4-1) in at least one life stage. They included yellow bullhead, yellow perch, Unidentified Catostomids, Unidentified Lepomids, and unidentifiable fish eggs (Class Osteichthyes). Although a common species in the region and in entrainment samples, yellow perch is not native to the middle Savannah River.

Its historical occurrence is more northern in range and it has been widely introduced elsewhere including the Savannah Basin (Marcy et al. 2005).

Table 5-1 provides a numerical comparison between species common to both source and entrainment sampling by sample type and life stage. No eggs were encountered in entrainment samples for any of the seven common species nor for any other species encountered during the source water study. Yolk-sac larvae were observed in both entrainment and source water samples for only one taxa group (Unidentified Lepomis). Post-yolk-sac larvae were encountered in both entrainment and source water samples in five of the seven common taxa/groups. The only species common to both source water and entrainment samples as a young-of-the-year life stage was yellow bullhead. Post-yolk-sac larvae represented 68 percent of the entrainment samples; whereas, eggs were the most abundant life stage collected from source water.

Although few samples were collected there, no single species was unique to the proposed intake location of Units 3&4 as compared to the primary transect sampling location. Source water samples were collected near the proposed location of Units 3&4 intake on two dates including late-May and early-June resulting in a mean fish egg and larva density of 52.9 organisms/ 1000 m3

During the same time as those sampling events, daytime egg and larval densities sampled from the primary transect were very comparable ranging from 29.5 to 52.8 organisms per 1OOO-m3 .

The siting study entrainment assessment performed in GPC' s 1974 studies of Plant Vogtle Units 1&2 relied on then-recent studies at the adjacent Savannah River Site LAB7600 26

(SRS) where intensive field studies demonstrated that fish eggs were rarely found in canal plankton samples. It was concluded then that eggs and larvae settled to the bottom of the intake canal before becoming entrained owing to substantially decreased water column velocities inside the canal as compared to the Savannah River (source water) where swifter current keep eggs and larvae in suspension in the drift. The indication was that eggs and larvae which entered the intake canal were not necessarily entrained further validated by the fact that sunfish, minnows, and silvers ides persisted in the SRS intake canal. Per the SRS studies, sunfish in particular were known to spawn in the intake canals and were the dominant species there year round. The early Plant Vogtle studies concluded that the Vogtle intake structure would be constructed in a similar manner as SRS intake structures and minimal entrainment would likewise result.

For perspective in evaluating the 2008 study results, findings from GPC's 1974 source water study and entrainment assessment were reviewed for comparison. The 1974 source-water study at Plant Vogtle utilized six sampling stations on the Savannah River (two net collection stations along three transects) and used ]-meter nets constructed of 760 u mesh. Egg and larval samples were collected during January through May and July through August with and average sample time per station of 15 minutes. A total of 89 day samples and 88 night samples were collected. The sampling resulted in collected of 1,423 eggs and 2,177 larvae with at least 34 species of fish represented. Overall, a greater number of eggs and larvae were collected at night. Peak drift abundance occurred during April and May with a sharp increase detected in July.

Crappie larvae were the largest contributor to the drift community accounting for 29.3 percent of the sample by American shad eggs (23.6 percent) and spotted sucker larvae (15. 7 percent). The highest densities, per 1000 m3 , were reported for Clupeidae, Catostomidae, and Centrarchidae.

For comparison, entrainment at the Savannah River Plant pump-house intakes, located a short distance upstream for Pant Vogtle, was estimated in 1982, 1983, 1984, and 1985. Several taxa especially gizzard shad in 1982 and 1983, crappie in 1983 and 1984, and spotted sucker in 1985 occurred in unusually high densities suggesting they were spawned in the canals. Species that spawned in the canals tended to exhibit increased entrainment. Entrainment losses averaged 10 x 106 eggs and 18.8 x 106 larvae annually (vs -3.1 x 10 5 total eggs and larvae at Plant Vogtle). Entrainment loses were primarily American shad and other herring species (clupeids). Entrainment was greatest during periods of high intake water usage which coincided with low river flow during the spawning season (in Kilgo et al. 2005).

LAB7600 27

Many aspects of the 2008 source water study at Plant Vogtle were comparable to the 1974 study. The 2008 study used a total ofthree sampling stations aligned along one of the same upstream river cross-sections used in the 1974 study. Additionally, three stations were sampled along a single cross-section near the proposed location of Units 3&4 on one occasion and again at one of those three stations on one other occasion. Samples were collected during longer periods (average time per station of 18.6 minutes) with nets using a smaller net opening and mesh size as compared to the 1974 study (15 minutes). Samples in 2008 were collected during March through July whish directly overlapped the 1974 sampling period .. Sixty-four day samples and 60 night samples were collected in 208 vs. 89 and 88 day and night samples in the 1974 study. More organisms were collected at night in 2008 just as observed in the 1974 study. Peak drift abundance in 1974 and 2008 occurred in April, May, with a sharp increase in July in 1974 and a pronounced peak in May in the 2008 study (without consideration for long- or short-term environmental, climatologic, or hydrological trends that may have influenced results during either study). Cyprinidae, in contrast to crappies (29 .3 percent were the single largest contributor to the drift population in 2008 accounting for 20.0 percent of the total. In 1974, American shad eggs accounted for 23.6 percent of the source water sample compared to 18.2 percent of the sample in 2008. In 2008, members of the Cyprinidae and Clupeidae were the largest contributors of yolk-sac and post-yolk-sac larvae in source water samples. The highest organism density recorded during the day in the 2008 study was exhibited by Unidentified Cyprinidae at 289.4 organisms/ I 000 m 3 American shad exhibited the highest density for nighttime samples as well throughout the study for a single species or event.

Highest organism densities in the 1974 study were observed in families of Clupeidae, Catostomidae, and Centrarchidae.

The 2008 source water study conducted at Plant Vogtle revealed the presence of egg and early larval forms through yearling life stage for a diversity (23) of fish species representative of recently documented fish fauna of the region. The observed trend in timing of recruitment and peak drift abundance were consistent with those documented in previous studies of the area. The 2008 entrainment study result was consistent with conclusions drawn from the 1974 siting studies in demonstrating that entrainment impact at Plant Vogtle is likely minimal owing to the relative absence of organisms in entrainment samples collected from the intake canal during period of peak riverine drift.

The low numbers of entrained organisms collected samples appear to likewise be related to the substantial differential decrease in water column velocity as source water is drawn from the river, partially deflected through the stop log gate and sediment catchment sheet pilings located in the mouth of the intake canal. Many semi-buoyant or LAB7600 28

demersal eggs and larvae that enter the canal, otherwise suspended in passing riverine currents, likely quickly settle into sedimentary substrates in the proximal end of the canal. Thus, most early life stage fishes entering the canal never reach the intake screens. The most abundant species entrained included only larval stages of yellow perch, unidentified suckers, and unidentified sunfishes. Owing to the type of habitat present in the canal, particularly sunfishes may even reside and spawn in the intake canal where suitable habitats and quiescent hydraulic conditions prevail. Localized and source water occurrence larval sunfishes in addition to abundance pulses of suckers and yellow perch from source water apparently contribute to the majority of entrainment based on sample results. The early GPC studies referred to SRP studies where it was stated that fish eggs carried by riverine flows were generally closer to the bottom and upon entering the intake canal encountered a sharp decrease in velocity and has a tendency to settle to the bottom resulting in low entrainment rates. The abundance of American shad eggs in particular in source water was not detected in entrainment samples indicating further that little entrainment occurs through the Plant Vogtle intake structure.

Overall, the 2008 entrainment assessment result combined with earlier GPC and SRP findings (and the fact that less than 2.2 percent of the Savannah River flow is withdrawn by the intake) indicate that entrainment effect at Plant Vogtle is minimal resulting in an insignificant effect on the fish population of the Savannah River.
