Dear Dr. Urban:

TENNESSEE VALLEY AUTHORITY (TVA) -WATTS BAR NUCLEAR PLANT (WBN) -NPDES PERMIT NO. TN0020168

-RENEWAL APPLICATION Enclosed are a signed original and a copy of the NPDES permit renewal application packet consisting of EPA Form 1, site map, Form 2C, Form 2C addendum, flow schematic, Form 2E, and a permit address form. Sampling for permit renewal occurred in December 2005 and historical data were compiled from the period of October 1, 2004, through September 30, 2005.TVA requests consideration of the following in the renewed permit application:

Outfall 101 Enclosed is a reasonable potential determination on the need for whole effluent toxicity (WET) testing for outfall serial numbers (OSNs) 101,102, 112, and 113 at WBN. WBN is currently required by the biocide corrosion treatment plan (BCTP) approved in July 2004 in conjunction with Part IV.B of the NPDES permit to monitor once per year during oxidizing biocide use and once per year during non-oxidizing biocide use. TVA requests that the NPDES permit be made consistent with that frequency by modifying the permit limits table to 2/year or to refer to a footnote indicating that WET testing would be required once per year for oxidizing biocides and once per year for non-oxidizing biocides.Outfall 102 Footnotes 4 and 6 appear to be incomplete sentences and should be corrected.

Printed on reycled paw Dr. Richard Urban Page 2 May 3, 2006 Internal Monitoring Point (IMP) 103 1. TVA requests that oil and grease (O&G) monitoring at IMP 103 be reduced to once per month. There have been no detectable values for more than five years. With zero variability and values that are well below the permit limit, this discharge represents a very low risk. In addition, this is an internal monitoring point that is routed to OSN 101, where O&G is monitored again and compared to a permit limit.2. TVA asks that the monitoring frequency for total suspended solids (TSS) be reduced to once per month. The maximum monthly average for the period from April 2001 to April 2006 was 23.6, below the permit limitation.

Since the Division's policy is to require compliance with the monthly average even when only one measurement is made per month, WBN should have no difficulties complying with the monthly average. In addition, this discharge is routed to OSN 101 where further TSS limits are applied.3. TVA requests that pH monitoring at this internal monitoring point be reduced to once per month since the pH is also monitored at OSN 101, the point at which the discharge reaches the receiving stream.Internal Monitoring Point (IMP) 107 1. TVA believes that the current monitoring frequency for pH on the metal cleaning waste pond should be changed to 1/batch, consistent with the monitoring frequency for TSS, O&G, etc. It is currently described as 1/week which is not appropriate since the discharge typically does not occur at that frequency.

2. TVA recently notified the Chattanooga Field Office requesting authorization for a discharge of waste water from condenser tube cleaning that had been filtered to 5 microns to address asbestos that may have been present. This discharge was authorized by email dated March 14, 2006. TVA requests that this intermittent wastewater be authorized in the renewed permit.Outfall 113 TVA requests that the requirement to monitor bottom temperatures at Outfall 113 be removed from the reissued permit. Reviewing data from April 2000 through April 2006 reveals that the maximum temperature recorded has been 29.3 degrees C while the permit limit is 33.5 degrees C. Removing this monitoring requirement appears to be very low risk as the data indicate no excursions and a reasonable margin of safety for protecting bottom temperatures.

Dr. Richard Urban Page 3 May 3, 2006 Part I1.C.3 TVA believes that the definition of overflow should be modified.

It is currently defined by this section of the permit as "Overflow means the discharge to land or water of wastes from any portion of the collection, transmission, or treatment system other than permitted outfalls." TVA believes the wording should be consistent with the wording of TCA 69-3-108(b)(5) which prohibits discharges of such wastes into waters or from "a location from which it is likely that the discharged substance will move into waters." Part Ill. E 1. TVA recently received written authorization to treat Pimephales promelas toxicity samples (both effluent and intake samples) with UV to address problems with pathogenic interference in WET testing. A copy of this authorization is enclosed for your convenience.

TVA requests that language be added to address this in the renewed permit. Suggested wording is; "The permittee is authorized to treat Pimephales promelas samples collected for toxicity testing at Outfall 112 with UV radiation for up to five minutes." 2. TVA believes the language regarding whole effluent toxicity being required during the first treatment after the effective date of the permit should be removed since the effective date is an unknown future date and the facility may already be in a treatment when the permit becomes effective.

TVA suggests that language requiring tests to be conducted within 180 days of the effective date of the permit if oxidizing or nonoxidizing treatments have been utilized should be sufficient.

Part Ill. I TVA requests inclusion of new language for the WBN permit, consistent with language found in Part Ill in all TVA fossil power permits in Tennessee which minimizes administrative burdens. The language is: The permittee shall be allowed to re-route flows past normal monitoring points as a temporary measure for maintenance purposes.

However, such re-routing must be done in such a way that permit limitations are still being met in the receiving waters and compliance with permit limitations is monitored and reported on the DMRs for the rerouted flows. The receiving waters must be the same for the rerouted flows as for the normal discharges.

TVA offers the following general information in support of the NPDES renewal application.

1. Outfall 102 was not discharging at the time of renewal sample collection; therefore, the data presented on the pages for Outfall 102 are only historical data Dr. Richard Urban Page 4 May 3, 2006 from the few times flow has emanated from there. OSN 102 is an alternate discharge to OSN 101 so the renewal data for 101 are representative of 102.2. Sampling for IMP 103 consisted of sampling Part II.A.-I.C.

parameters only.IMP 103 is internal to OSN 101 where all required categories of pollutants were evaluated and sampled per EPA Form 2C instructions.

3. IMP 107 was not discharging during permit renewal sampling.

This IMP is also internal to 101 where all required categories of pollutants were evaluated and sampled per Form 2C instructions; only historical data from IMP 107 are presented on the forms.4. Outfall 112 consists of sanitary wastewater, potential cooling tower blowdown and fire protection flushes and storm water runoff.5. Outfall 114 which consists of traveling screen backwash only from the supplemental condenser cooling water intake has been added to the permit application.

This outfall consists of screen reject and raw water only. TVA requests no monitoring requirements, consistent with other screen backwash discharges at TVA facilities.

6. TVA is providing a copy of the report "Biological Monitoring of the Tennessee River near Watts Bar Nuclear Plant Discharge 2004 (June 2005 Final)" for your use.TVA appreciates your consideration of the information provided herein in the development of the reissued permit. If you have any questions about this NPDES permit renewal application, please contact Lindy Johnson at (423) 751-3361 in Chattanooga, or you may contact her by email at Ipjohnson@tva.gov.

TVA requests an expeditious determination of completeness of the application.

'-'I EPA Form 3510-2C (8-90)Page 4 of 4 TNO020168 WBN PROCESSES 2C Addendum Chemicals Used~in Plant Processes Chemical additives are used in plant processes and may be found in trace quantities in the various NPDES discharge points due toblowdown, leakage, and system maintenance activities.

The following paragraph describes the most commonly used system additives.

A table on the next page summarizes all chemical additives including the raw water additives that may be found in each outfall as well. The raw water additives are biocides and corrosion treatment chemicals and are discussed in more detail in the Biocide Corrosion Treatment Plan (BCTP) approved in July 2004 by the Division of Water Pollution Control.Hydrazine, ammonia, boric acid, sodium tetraborate, monoethanolamine, sodium molybdate, sodium tolyltriazole, potassium hydroxide, and lithium hydroxide are routinely added to the Primary and Secondary Systems to control pH and corrosion.

Up to 300 pounds of modified alpha cellulose could be added to the condenser intake channel to temporarily plug pinhole tube leaks in the condenser.

Hydrogen peroxide may be added during refueling for Primary System cleanup to reduce radiation exposure to maintenance personnel.

Similarly, small quantities of ethylene glycol, a heat transfer medium used in building chiller packages, the ice condenser chiller packages, and diesel generators, could end up via leakage or maintenance activities in OSNs 101, 102, internal monitoring point (IMP) 103, and IMP 107.4/26/06 TNO020168 WBN PROCESSES 2C Addendum

Mark "X" in column 2-a for all such GCIMS 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 ouffalls, 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, acrylonitrile, 2,4 dinltrophenol, 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.

Dear Mr. Park:

This responds to the request made on behalf of TVA, dated February 7, 2006, for written division approval to allow effluent samples from outfall 112 at Watts Bar, outfall 002 at Cumberland, and outfall 002 at Kingston to be treated, for toxicity testing on Pimephalespromelas, with UV radiation.

The division has reviewed the request and hereby approves the use of UV radiation at the above referenced facilities as proposed in your letter.If you have any questions regarding this correspondence please feel free to contact me at 615-532-0672.Sincerely, Christopher S.

Re: question about UV letter Lindy -I agree that it is appropriate to treat both the effluent and intake samples. I think in drafting the letter responding to your request, we did not take into account that the permits allow testing of intake water. Please let me know if you need anything more formal than this email.Chris Moran, Manager Enforcement

& Compliance Division of Water Pollution Control>>> "Johnson, Lindy P." <lpjohnson@tva.gov>

04/14/06 8:43 AM >>>Hi Chris, We were getting together our next toxicity test for Watts Bar Nuclear Outfall 112 (happily with the ability to treat samples with UV). In the letter, you state that we are authorized to treat effluent samples with UV. My question is (after talking with our toxicologist), shouldn't we also be authorized to treat our intake samples so we are appropriately comparing intake to effluent? (I think our earlier request just requested authorization to treat samples.)Treating intake samples could also prevent us from having to invalidate tests due to intake toxicity due to pathogenic interference.

Would you be agreeable to treating intake samples as well under the same conditions authorized in your letter for effluent samples? Please advise.Thanks.Lindy Printz Johnson Tennessee Valley Authority Environmental Affairs, LP SD-C.phone: 423 751 3361 fax: 423 751 7011 email: /piohnsonctva.,gov 04/21/2006 TENNESSEE VALLEY AUTHORITY (TVA) -WATTS BAR NUCLEAR PLANT (WBN) -NPDES PERMIT NO.

= 2/year, one during oxidizing biocide treatment and one during non-oxidizing biocide treatment Outfalls 101 and 113: In accordance with EPA's recommendation (Technical Support Document for Water Quality-based Toxics Control, EPA/505/2-90-001), WBN Outfall OSN101 and Outfall OSN113 would not be required to have chronic WET limits based on a demonstration of no Reasonable Potential (RP) for excursions above the ambient water quality chronic (CCC) criterion using effluent data for current operating conditions.

Following guidance in the Technical Support Document (TSD), when no RP exists, biomonitoring would be conducted at a frequency of only once every 5 years as part of the permit renewal process to document acceptable effluent toxicity and toxicity at the instream wastewater concentration (IWC) would serve only as a hard trigger for accelerated toxicity biomonitoring.

However, raw water used at the facility is treated with corrosion inhibitors and biocide products.

These products, which can become concentrated in the cooling tower system, are discharged through Outfalls 101 and 113. The chemical makeup of the products used can change during the permit period and the combined toxicity effect of the chemicals is not known. Thus it is not feasible to control toxicity only by the application of chemical specific effluent limits to the discharge.

Toxicity testing is a reasonable method to evaluate the toxicity impacts of the products in the effluent.

Therefore, TVA believes it is appropriate to maintain the current WET requirements for WBN Outfalls OSN101 and OSNI 13 that are specified in the Biocide Corrosion Treatment Plan (BCTP), approved by letter on dated July 30, 2004, with one test per outfall during oxidizing biocide treatment and one test per outfall during non-oxidizing biocide treatment.

TVA is requesting permit language consistent with the BCTP.The following RP determination utilizes nine years (19 studies) and six years (13 studies) of WET biomonitoring data collected for Outfalls 101 and 113, respectively.

Only I025 based studies were used in this determination.

Table 1 summarizes Outfall 101 biomonitoring results while Table 3 summarizes Outfall 113 biomonitoring results.Outfall 102: Sampling and analysis of Outfall OSN 102 has not been required under the current permit since the conditions for biomonitoring were not met. No RP determination was made for this Outfall.

Outfall 112: In accordance with EPA's recommendation (Technical Support Document for Water Quality-based Toxics Control, EPA/505/2-90-001), WBN Outfall OSN112 should retain its WET chronic limit based on a demonstration of Reasonable Potential (RP) for excursions above the ambient water quality chronic (CCC)criteria usinq effluent data. The following RP determination utilizes nine years (28 studies) of WET biomonitoring data collected for Outfall 112. Only IC 2 5 based studies were used in this determination.

Table 2 summarizes Outfall 112 biomonitoring results obtained during the last twelve years.

SSS Spring Sport Fish Survey TRM Tennessee River Mile TVA Tennessee Valley Authority VS Vital Signs WBN Watts Bar Nuclear Plant Wr Relative Weight iv Introduction Section 316(a) of the Clean Water Act specifies that industrial, municipal, and other facilities must obtain permits if their discharges go directly to surface waters. Industries responsible for point-source discharges of heated water can obtain a variance from state water quality standards if the industry can demonstrate compliance with thermal criteria by documenting the maintenance of Balanced Indigenous Populations (BIP) of aquatic life in the vicinity of its discharge.

Historically, the Tennessee Valley Authority (TVA) used special studies to evaluate affects on aquatic life in the vicinity of its power plant discharges.

In July 1999, a Supplemental Condenser Cooling Water (SCCW) system went on line at TVA's Watts Bar Nuclear Plant (WBN). As required by WBN's National Pollutant Discharge Elimination System (NPDES) permit TN0020168,1 impacts to aquatic communities in the vicinity of WBN and Watts Bar Reservoir forebay were evaluated.

Baxter et al. (2001) recommended components of TVA's Vital Signs (VS) monitoring program (Dycus and Meinert 1993), the Reservoir Fish Assemblage Index (RFAI) and Benthic Macroinvertebrate Index (BI) to WBN management as a means of assessing Chickamauga and Watts Bar Reservoirs' aquatic community integrity while the SCCW is operational.

The purpose of this document is to briefly summarize-and prcvide results of the Calendar Year 2004 monitoring and analyses to the Tennessee Department of Environment and Conservation and compare these results with historical monitoring data.Prior to 1990, TVA reservoir studies focused on reservoir ecological assessments to meet specific needs as they arose. In 1990, TVA instituted a Valley-wide VS monitoring program which is a broad-based evaluation of the overall ecological conditions in major reservoirs.

Data is evaluated with a multi-metric monitoring approach utilizing five environmental indicators:

dissolved oxygen, chlorophyll, sediment quality, benthic macroinvertebrate community, and the fish community.

When this program was initiated, specific evaluation techniques were developed for each indicator, and these techniques were fine-tuned to better represent ecological conditions.

The outcome of this effort was development of multi-metric evaluation techniques for the fish assemblage (i.e., RFAI) and the benthic community, as described below. These multi-metric evaluation techniques have proven successful in TVA's monitoring efforts as well as other federal and state monitoring programs.

For consistency, only RFAI analyses between 1993 and 2004 will be utilized.

The BI is used primarily to support the RFAI analysis.The Sport Fishing Index (SFI) was developed to quantify sport fishing quality for individual sport fish species. The SFI relies on measurements of quantity and quality aspects of angler success and fish population characteristics.

This provides biologists with a reference point to measure the quality of a sport fishery. Comparison of the population sampling parameters and creel results for a particular sport fish species with expectations of these parameters from a high quality fishery (reference conditions) allows for the determination of fishing quality. Indices have been developed for black bass (largemouth, smallmouth and spotted bass), sauger, striped bass, bluegill, and channel catfish.I In recent years, SFI information has been used to describe the quality of the resident fishery in conjunction with compliance monitoring, thermal variance requests, and other regulatory issues at TVA nuclear plants in Tennessee.

Similar NPDES compliance monitoring programs using the methodologies described above are also being performed at Browns Ferry Nuclear, Colbert and Widows Creek Fossil Plants in Alabama.Based on the RFAI and benthic macroinvertebrate analyses, TVA biologists have concluded that the SCCW and WBN operation had no effect on the fish and benthic macroinvertebrate communities in the vicinity of WBN and Watts Bar Reservoir forebay during Calendar Year 2004.The TVA Spring Sport Fish Survey (SSS) is conducted to evaluate the sport fish population of TVA Reservoirs.

The results of the survey are used by state agencies to protect, improve and assess the quality of sport fisheries.

Predominant habitat types in the reservoir are surveyed to determine sport fish abundance.

In addition to accommodating TVA and state databases, this surveying method aligns with TVA Watershed Team and TVA's Reservoir Operations Study objectives.

Sample sites are selected using the shoreline habitat characteristics employed by the Watershed Teams. The survey predominantly targets three species of black bass (liargemouth, smallmouth, and spotted bass) and black and white crappie. These species are the predominant sport fish sought after by fisherman.

Methods Fish Community Reservoirs are typically divided into three zones for VS monitoring

-inflow, transition and forebay. The inflow zone is generally in the upper reaches of the reservoir and is riverine in nature; the transition zone or mid-reservoir is the area where water velocity decreases due to increased cross-sectional area, and the forebay is the lacustrine area near the dam. The Chickamauga Reservoir inflow zone sample site is located at Tennessee River Mile (TRM)529.0, the transition zone is sampled at TRM 490.5, and the forebay zone sample site is located at TRM 472.3. The VS inflow zone starts below Watts Bar Dam at TRM 529 and extends downstream to TRM 526.3. This station is used to provide downstream data for the 316(a)thermal variance studies performed in 1993 to 1995, 1997, and 1999 to 2004. Since the WBN discharge is located within Chickamauga Reservoir inflow zone, no upstream control site data are available for comparison.

Watts Bar Reservoir forebay site (TRM 531) will be used to document any notable changes in Tennessee River ecological conditions above the WBN discharge but will not be used for upstream/downstream comparisons of RFAI scores.Fish samples consisted of fifteen 300-meter electrofishing runs (approximately 10 minutes duration) and ten experimental gill net sets (five 6.1 meter panels with mesh sizes of 2.5, 5.1, 7.6, 10.2, and 12.7 cm) per site. Attained values for each of the 12 metrics were compared to reference conditions for transition zones of lower mainstream Tennessee River reservoirs and assigned scores based upon three categories hypothesized to represent relative degrees of degradation:

least degraded -5; intermediate

-3; and most degraded -1. These categories are 2 based on "expected" fish community characteristics in the absence of human-induced impacts other than impoundment.

Individual metric scores for a site are summed to obtain the RFAI score.Comparison of the attained RFAI score from the potential impact zone to a predetermined criterion has been suggested as a method useful in identifying the presence of normal community structure and function and hence existence of a BIP. For multi-metric indices, two criteria have been suggested to ensure a conservative screening for a BIP. First, if an RFA score reaches 70 percent of the highest attainable score (adjusted upward to include sample variability), and second, if fewer than half of RFAI metrics potentially influenced by thermal discharge receive a low (1) or moderate (3) score, then normal community structure and function would be present indicating that a BIP existed. Under these conditions the heated discharge would meet screening criteria and no further evaluation would be needed.The range of RFAI scores possible is from 12 to 60. As discussed in detail below, the average variance for RFAI scores in TVA reservoirs is 6 (+ 3). Therefore, any location that attains an RFAI score of 45 (42 + our sample variance of 3) or higher would be considered to demonstrate a BIP. It must be stressed that scores below this endpoint do not necessarily reflect an adversely fish community.

The endpoint is used to serve as a conservative screening levei; for example, any fish community that meets these criteria is obviously not adversely impacted.RFAI scores below this level would require a more in-depth look to determine if a BIP exist. If a score below this criterion is obtained, an inspection of individual RFAI metric results would be an initial step to help identify if WBN operation is a contributing factor. This approach is appropriate if a validated multi-metric index is being used and scoring criteria applicable to the zone of study are available.

The Quality Assurance (QA) component of VS monitoring deals with how well the RFAI scores can be repeated and is accomplished by collecting a second set of samples at 15-20 percent of the sites each year. Previous statistical analyses with the QA component of VS has shown that the comparison of RFAI index scores from 54 paired sample sets collected over a seven year period ranged from 0 to 18 points. Based on these findings, the 7 5 th percentile is 6 and the 9 0"h percentile is 12. The mean difference between these 54 paired scores is 4.6 points with 95 percent confidence limits of 3.4 and 5.8. Therefore, a difference of 6 points or less was the value selected for defining "similar" scores between upstream and downstream fish communities.

That is, if the downstream RFAI score is within 6 points of the upstream score, the communities will be considered similar. It is important to bear in mind that differences greater than 6 points can be expected simply due to method variation (25 percent of the QA paired sample sets exceeded that value). When this occurs, a metric-by-metric examination will be conducted to determine what caused the difference in scores and the potential for the difference to be thermally related.Benthic Macroinvertebrate Communitv Ten benthic grab samples were collected at equally spaced points along the upstream and downstream transects.

A Ponar sampler was used for most samples but a Peterson sampler was used when heavier substrate was encountered.

Collection and processing techniques followed standard VS procedures.

Bottom sediments were washed on a 5 33p. screen; organisms were then 3 picked from the screen and remaining substrate and identified to Order or Family level in the field using no magnification.

Benthic community results were evaluated using seven community characteristics or metrics. Results for each metric were assigned a rating of 1, 3, or 5 depending upon how they compared to reference conditions developed for VS sample sites. The ratings for the seven metrics were summed to produce a total benthic score for each sample site. Each reservoir section (inflow, transition, or forebay) differs in their maximum potential for benthic diversity; thus, the criteria for assigning metric ratings were adjusted accordingly such that the total benthic scores from sites on different reservoir sections are comparable.

Potential scores ranged from 7 to 35. Ecological health ratings ("Poor," "Fair,", or "Good") are then applied to scores. A similar or higher benthic index score at the downstream site compared to the Watts Bar forebay site is used as basis for determining WBN's absence of impact on the benthic community.

The QA component of VS monitoring shows that the comparison of benthic index scores from 49 paired sample sets collected over a seven year period ranged from 0 to 14 points, the 7 5 th percentile was 4, the 9 0 th percentile was 6. The mean difference between these 49 paired scores was 3.1 points with 95 percent confidence limits of 2.2 and 4.1. Based on these results, a difference of 4 points or less is the value selected for defining "similar" scores between upstream and downstream benthic communities.

That is, if the downstream benthic score is within 4 points of the upstream score, the communities will be considered similar. Once again, it is important to bear in mind that differences greater than 4 points can be expected simply due to method variation (25 percent of the QA paired sample sets exceeded that value). When this occurs, a metric-by-metric examination will be conducted to determine what caused the difference in scores and the potential for the difference to be thermally related.Sport Fishing Index Calculations described by Hickman (2000) were used to compare SFI values for selected quantity and quality parameters from creel and population samples to expected values that would occur in a good or high quality fishery. Quantity parameters include angler success and catch per unit effort from standard population samples (electro fishing, trap and experimental gill netting).Population quality is based on measurement of five aspects of each resident sport fish community.

Four of these aspects address size structure (proportional number of fish in each length group) of the community, Proportional Stock Density (PSD), Relative Stock Density of Preferred-sized fish (RSDP), Relative Stock Density of Memorable-sized fish (RSDM), and Relative Stock Density of Trophy-sized fish (RSDT) (Figure 1). Relative weight (Wr), a measure of the average condition of individual fish makes up the fifth population quality aspect.As described by Hickman (2000), observed values were compared to reference ranges and assigned a corresponding numerical value. The SFI value is calculated by adding the scores for quantity and quality from existing data and multiplying by two when only creel or population data are available.

Species received a low score when insufficient numbers of individuals were captured to reliably determine proportional densities or relative weights for particular parameters.

SFI scores are typically compared to average Tennessee Valley reservoir scores; however, Valley-wide scores are unavailable from natural resource agencies.

Therefore, Chickamauga 4

Reservoir fish species scores will be compared to previous years. The 2004 State Fisheries gillnetting and creel data were not available for analysis before this report was published; therefore 2003 SFI data were used for analysis.Spring Sport Fish Survey A spring sportfish survey was conducted on Watts Bar Reservoir April 2004. Twelve sites at four locations including Watts Bar Dam, Blue Springs, Caney Creek and Center's Ferry were sampled using boat-mounted electrofishers.

Each run consisted of thirty minutes of continuous electrofishing in the littoral zones of prominent habitat types represented in the reservoir.

Summer pool lex el for Watts Bar is 741.0 msl and sampling was conducted at 740.5 msl.TVA Fisheries Biologists use electrofishing equipment to sample fish at selected locations.

In that process an electric current is used to temporarily stun the fish so they float to the surface of the water. The fish are collected with nets, counted, weighed, measured, and released unharmed.Each run consisted of thirty minutes of continuous electrofishing, a total of twenty-four hours, in the littoral zones of prominent habitat types represented in the reservoir.

Results of the SSS monitoring were calculated using Shoreline Assessment Habitat Index (SAHI), Relative Stock Density (RSD), PSD, and Wr.Habitat type is evaluated using the SAHI metric and is a critical component incorporated into the spring sport fish survey. The resultant habitat designations (good, fair and poor) are correlated to black bass abundance (numbers/hour).

RSD is the number of fish greater than a minimum preferred length in a stock divided by the number of fish greater than or equal to a minimum stock size.PSD is the number of fish greater than or equal to a minimum quality length in a sample divided by the number of fish greater than or equal to a minimum stock length.Wr is an index that quantifies fish condition and the preferred range value is 90-105% for moderate density bass populations such as those found in the Tennessee Valley latitudes.

Results and Discussion Fish Community In the autumn of 2004, R.FAI results from the downstream site received the RFAI score of 42 (Good) indicating that resident fish community below the WBN discharge was above the screening level and considered to have BIP (Table 1). In fact, the inflow site averaged an RFAI score of 46 for the last ten sample years (Table 2). The RFAI scores for the inflow site remained in the good to excellent ecological health range for all sampling seasons (Figures 2 and 3). Watts Bar Reservoir RFAI forebay data collected between 1993 and 2004 reflect little change in the overall ecological health of the fish communities at this site (Figure 3). Five of the eight sample seasons scored in the good range; the other three sample seasons were only slightly below the good range illustrating only slight variability in ecological health. Watts Bar Reservoir forebay 5 reached 75 percent of its highest potential RFAI score (Tables 2 and 3) and Chickamauga inflow reached 70 percent of its highest potential score in sample year 2004 (Tables 1 and 2) indicating that a BIP exists downstream of the WBN discharge and that neither the operation of WBN or SCCW are adversely affecting fish communities in the vicinity of the discharge.

Electrofishing and gill netting catch rates for individual species collected in Chickamauga Reservoir downstream of the discharge are listed in Tables 4 and 5. Thirty two species were collected at the inflow site in 2004 (Table 5) compared to 29 species collected in 2003 (Baxter and Gardner 2004).Benthic Macroinvertebrate Community Table 6 provides results and ratings for each metric as well as the overall benthic index score for three monitoring sites: one site upstream and two sites downstream from WBN. Table 7 summarizes density by taxon at the downstream collection site (TRM 527.4). The sample from Watts Bar Reservoir forebay (TRM 532.5) was field processed and no lower level taxonomic identifications were made. In 2004 samples, the Watts Bar forebay station had a benthic index score of 17 ("Poor") while both the Chickamauga Reservoir downstream sites (TRM 527.4 and TRM 518) scored 33 ("Good").

Therefore, WBN has not had an effect on the benthic macroinvertebrate community immediately downstream from the plant.Table 8 provides benthic index scores from VS monitoring at the forebay, inflow, and transition zone sites on Chickamauga and Watts Bar reservoirs from 1994 through 2004. The Chickamauga transition zone sample site (TRM 490.5) is of sufficient distance downstream (37 miles) such that results would not be expected to reflect plant effects. In 2004, both sites immediately downstream from WBN (TRM 527.4 and TRM 518) produced a score of 33 (excellent).

This suggests that WBN has had no effect on the macroinvertebrate community immediately downstream from the plant.Sport Fishing Index In the autumn of 2003, Chickamauga Reservoir's sport fish population received similar SFI scores compared to the seven year average. Black bass, largemouth bass, smallmouth bass, spotted bass, crappie and white bass received higher scores than their seven year averages (Table 9 and Figure 4). Both sauger and striped bass received lower scores in 2003 compared to scores in 2002. The score for sauger was the lowest it has been since 1997 when this analysis technique was implemented by TVA. This quality assessment is not necessarily indicative of a trend.Historical data indicate that SFI scores typically vary across years. However if future scores continue to decline, further investigation would be warranted.

Channel catfish, crappie and white bass received their highest SFI scores to date. Crappie and white bass scores increased from 38 to 42 and 30 to 40, respectively (Table 9 and Figure 4).SFI results for Watts Bar Reservoir's black bass species received lower scores in 2003 compared to their seven year averages (Table 10). Bluegill, white and striped bass received higher scores than their seven year averages (Table 10 and Figure 5).6 Tables 11 and 12 illustrate SFI scoring criteria for population metrics and creel quantity and quality.Sauger, striped bass, and channel catfish are easily caught during their spring migration to preferred spawning habitats.

Fishing creel surveys conducted in the spring would better describe and evaluate these species compared to only using autumn fisheries surveys.Spring Sport Fish Survey Chickamauga Reservoir A total of 18 hours2.083333e-4 days <br />0.005 hours <br />2.97619e-5 weeks <br />6.849e-6 months <br /> of electrofishing resulted in 736 black bass collected; of these, 60.2% were harvestable size (10" or greater).

Of the total black bass collected, 579 were largemouth, 120 were spotted and 37 were smallmouth bass. Overall catch rate (40.9 fish/hr.)

was less than the 2003 survey (62.0/hour) (Table 13). The average weight of harvestable sized black bass was 1.3 pounds. The largest black bass collected was s 6.6 pound largemouth bass taken from Skull Island. Numbers of lunker bass were well represented with a total of 21 bass greater than three pounds, 13 greater than four pounds and 6 over five pounds. In 2003, 23 bass over four pounds were collected and eight of them were five pounds plus.Length frequency histograms illustrated a bimodal distribution with the dominant size classes being the 10-11 inch and 13-14 inch groups (Figure 6). Good representation of the memorable category sized fish was also evident.Habitat type is a critical component that has been incorporated into the spring sportfish survey.This metric is derived from the SAHI developed by Resource Stewardship.

The resultant habitat designations (good, fair and poor) are correlated to black bass abundance (numbers/hour).

A positive correlation of habitat type-to-black bass abundance was evident on Chickamauga Reservoir during the 2004 survey. Among the three areas sampled, the correlations at Skull Island were positive but Sale Creek and Harrison Bay showed some variability among habitat types, i.e., the catch rates (abundance) did not align with the habitat designation types (Table 14).Overall catch rates for the reservoir were 49, 42 and 31 at the good, fair and poor habitats, respectively (Table 15).RSD is the number of fish greater than a minimum preferred length in a stock divided by the number of fish greater than or equal to a minimum stock size. The RSD value (15) fell within the desirable range (10-25) (Figure 7). The PSD is the number of fish greater than or equal to a minimum quality length in a sample divided by the number of fish greater than or equal to a minimum stock length. The PSD value (53) was also within the preferred range (40-70) (Figure 8). Wr is an index that quantifies fish condition and the preferred range value is 90-105% for moderate density bass populations such as those found in the Tennessee Valley latitudes.

The values shown in Figure 9 are designated by inch groups which reflect the classical categories, i.e., 0-7 = substock, 8-11 = stock, 12-14 = quality, 15-19 = preferred, 20-24 = memorable and 25+ =trophy. All categories fell within the desired range, which reflects excellent condition of black bass in all size groups of the population.

Field observations of large numbers of prey fish indicate an abundance of forage for all size classes of black bass.7 A total of 106 crappie (88 black and 18 white crappie) were also collected during the survey.--- The crappies were collected predominantly from tree tops, stumps and other physical structures in shallow water.Watts Bar Reservoir A total of 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> of electrofishing resulted in 1,246 black bass collected; of these, 88.2% were harvestable size (10" or greater).

Of the total black bass collected, 1,011 were largemouth, 157 were spotted and 78 were smallmouth bass. Overall catch rate (51.9 fish/hr.)

was similar to the last three years surveyed (Table 16). The average weight of harvestable sized black bass was 1.5 pounds. The largest black bass was a 5.9 pound largemouth bass taken from Kingston.

Numbers of lunker bass were up from last year's survey. A total of 13 bass over four pounds were collected and 2 of these were over five pounds.Length frequency histograms illustrated a typical bell-shaped curve with the dominant size class being the 14-15 inch group (Figure 10). All size classes up to 22 inches were represented in the population.

Habitat type is a critical component that has been incorporated into the spring sportfish survey.This metric is derived from the SAHI dt 'eloped by Resource Stewardship Group. The iesultant habitat designations (good, fair and poor) are correlated to black bass abundance (numbers/hour).

A positive correlation occurred at Blue Springs and Kingston sites. At Watts Bar Dam and Caney Creek the catch rate-to-black bass abundance was more variable (Table 14). The overall reservoir catch rates were 68, 47 and 44 fish/hour at the good, fair and poor habitat types, respectively (Table 15).RSD is the number of fish greater than a minimum preferred length in a stock divided by the number of fish greater than or equal to a minimum stock size. The RSD value (24) fell within the desirable range (10-25) (Figure 7). The PSD is the number of fish greater than or equal to a minimum quality length in a sample divided by the number of fish greater than or equal to a minimum stock length. The PSD value (84) was outside the preferred range (40-70) (Figure 8).Wr is an index that quantifies fish condition and the preferred range value is 90-105% for moderate density bass populations such as those found in the Tennessee Valley latitudes.

Relative weight data for Watts Bar fell within the desirable range of 90-105% indicating a balanced population structure of healthy, robust fish (Figure 11).A total of 237 crappie (136 black and 101 white crappie) were collected during the survey.8 Literature Cited Baxter, D.
