INTRODUCTION The Tennessee Valley Authority (TVA) is evaluating potential environmental impacts associated with renewing the operating licenses for Units 1 and 2 at its Watts Bar Nuclear Plant (WBN). TVA began construction on WBN in 1973, but Unit 1 did not begin full operation until
,1996. Due to a predicted reduction in demand for power, TVA suspended the construction of Unit 2 in 1988. In 2007, the TVA board decided to reinitiate construction of Unit 2, which is predicted to be completed by 2013.
WBN is located in Rhea County, Tennessee. It is adjacent to the Chickamauga Reservoir near Tennessee River Mile (TRM) 528 on the right descending bank, approximately two river miles below Watts Bar Dam. WBN is operated in closed cycle mode, using one of the two cooling towers for heat dissipation. Blowdown from the cooling towers is discharged through multi-port diffusers located in the main river channel at TRM 527.8. Makeup water and other raw water requirements of the facility are obtained from the intake pumping station at TRM 528. The WBN Supplemental Condenser Cooling Water (SCCW) system became operational in July 1999. The SCCW system withdraws water from the intake structure located immediately upstream of Watts Bar Dam at TRM 529.9, which formerly served Watts Bar Fossil Plant. The temperature of the water in the SCCW system reduces the temperature of the Unit 1 'condenser flow when mixed within the Unit 2 Cooling Tower Basin, which enhances the performance of the steam cycle.
Water from the SCCW system is discharged through the old Watts Bar Fossil Plant discharge structure located on the Tennessee River approximately TRM 529.1, which is 1.1 miles upstream of the nuclear plant intake.
The purpose of this study is to evaluate the current status of mussels (Family: Unionidae),
snails, and their habitat at three long-term monitoring sites near WBN.
An additional sampling location was also surveyed to determine the efficacy of an experimental boulder field for enhancing mussel habitat within areas affected by releases from Watts Bar Dam (Figure 1, page 2).
TVA contracted Third Rock Consultants, LLC (Third Rock) to conduct a survey to characterize mussels, snails, and their habitat along the project area.
Third Rock coordinated with Mainstream Commercial Divers to conduct the dive effort.
Dr. Monte McGregor served as malacologist.

SITE DESCRIPTION A.
Mollusk Sampling Sites Three reaches of the Tennessee River in the vicinity of WBN were surveyed using semi-quantitative and quantitative sampling methods similar to those used in past monitoring efforts to facilitate collection of comparable mussel and habitat data (Figure 1, page 2) including additional characterization of the snail community. The Upstream Site (TRM 528-529L) is located on the opposite side of the river and upstream from WBN. The Middle Site (TRM 526-527R) is located on the same side of the river as WBN and immediately downstream from the mouth of Yellow Creek and WBN discharges.
The Downstream Site (TRM 520-521 L) is located six river miles downstream and on the opposite side of the river from WBN. All three sites are along the inside edge of the navigation channel (near the overbank) in water approximately 3 to 7 meters (approximately 10 to 20 feet) deep.
Each of the three sites consisted of four sampling locations (transects) resulting in a total of 12 transects. At each location, a 100-meter long sampling transect (lines weighted to the riverbed), marked at 10 meter intervals, was anchored perpendicular to the bank and was used as a sampling guide by divers.
Semi-quantitative samples were taken along each 10-Prepared by: Third Rock Consultants, LLC November 2010 For: Tennessee Valley Authority

GPS coordinates (Tennessee State Plane, NAD1983) of the transect endpoints and any other notable features were recorded.
B.
Boulder Field Site Additional sampling was conducted within a man-made boulder field at approximately TRM 529.5.
The Boulder Site is an experimental site where boulders were placed in the river to reduce riverbed substrate movement with the anticipation of improving habitat for mussels and fostering habitat suitable for reproduction (Figure 1, page 2).
Ill.
MUSSEL AND HABITAT SURVEY METHODS Semi-quantitative Sampling. A total of 120 semi-quantitative samples were collected during the survey (40 per site).
Four 100-meter long sampling transects were placed at historic collection locations in the three different sampling reaches (Upstream, Middle, and Downstream)
(Ahlstedt 1991; Fraley et al. 2002).
Divers collected all mussels (live and dead) and snails within 10 square-meter sample areas (1 meter wide by 10 meters long) along one side of each transect for a total sample area of 100 square meters per transect. Each 10 square meter area was exhaustively searched by the diver. A minimum of five minutes search time was spent per increment to ensure complete and thorough coverage, except where consistently poor habitat (e.g., bedrock or deep silt) was encountered.
Actual time spent per sample was recorded to facilitate catch per hour calculations in conjunction with estimates of mussel and snail densities.
The diver used visual and tactual (disturbing the substrate by hand) search methods, placing all live and dead mussels into a mesh collection bag that was retrieved and processed in the boat. The mesh size of the collection bag was 6 millimeters. Small juveniles and snails encountered during the survey were placed in a bag with a mesh size of 3 millimeters.
Quantitative Sampling.
Quantitative samples were collected at the end of each 10-meter transect, resulting in 40 quantitative samples per site.
For quantitative samples, the diver excavated a whole-substrate sample from a 0.5-meter by 0.5-meter (0.25 square meter) quadrat.
Samples were excavated to a depth of 10 to 15 centimeters, and material was placed into a 19-liter (5 gallon) bucket. Samples were sent to the boat for processing. Quantitative samples were processed by sieving the sample material through a series of nested sieves, with the smallest mesh size being no larger than 3 millimeters.
Quantitative samples were collected at the end of each 10-meter increment on the opposite side of the transect line from where the semi-quantitative sample was collected.
Boulder Sampling Site: In 2000, an experimental effort to enhance native mussel habitat by providing refuge from high flow events resulting from dam discharges an artificial boulder field was created approximately 1 mile downstream of Watts Bar Dam.
Specifically, the site was located along the right descending margin of the navigation channel between the loading facility at Watts Bar Fossil Plant and the intake structure for Watts Bar Nuclear Plant. Limestone boulders measuring at least 2 to 4 feet in any dimension were placed in six rows of 10 boulders each in an area covering approximately 70 by 100 feet (Fraley et al 2002). Mussels were then stocked in three experimental plots, four corners of which were delineated with steel bars (= rebar). During the 2010 survey, an attempt was made to relocate those plots to determine the effectiveness of the boulders to enhance mussel habitat.

Page 4 of 24 Mollusk Survey of the Tennessee River Near Watts Bar Nuclear Plant Rhea County, Tennessee Sample Processing. A qualified malacologist with valid state and federal collecting permits identified and counted all live mussels and snails.
Copies of current federal and state collecting permits to collect mussels were provided to the TVA Project Biologist prior to the survey (e.g.,
with the cost estimate) and were in-hand while on site. The onsite malacologist was responsible for ensuring proper handling of mussel and snail resources, accurate and complete collection of data, and adherence to the TVA work plan. All live unionid mussels (or up to 50 individuals of each common species if densities were high) were measured (length in whole millimeters) and aged (external annuli count) to document recruitment and age/size profiles of each population. An effort was made to measure and age all individuals within quantitative samples, with individuals from qualitative samples having lower priority if some individuals were omitted.
Sex of sexually dimorphic species was recorded along with reproductive state (gravid/non-gravid) of female mussels if possible.
Length, height, age, and digital image (with size reference) were recorded for all live individuals of federally listed species. Dreissena polymorpha (zebra mussel) infestation rates (e.g., percent coverage of shell) were noted for live unionid mussels.
Snails collected during the survey were quantified, but not measured.
During processing, live mussels were kept wet and cool within mesh collection bags submerged in the river, and out-of-water time during processing was less than five minutes. Exposure to extreme temperature changes was avoided.
All mussels from quantitative samples were processed via screening the contents of the bucket through a series of stacked sieves (12 millimeter and 6 millimeter mesh sizes).
Contents were rinsed with river water and all live mussels were handpicked from the screens.
Non-listed mussel species were carefully returned to the river from the water surface (boat) along each transect in the general area from which they were collected.
All federally listed mussels collected were returned by hand to the location from which they were collected. No live individuals of federally listed mussels were harmed or removed from the site. Digital images of each representative species encountered during the survey were recorded.
No live individuals were harmed or removed from the site.
Dead unionids (shells only) were scored as either freshly dead (with or without soft tissues, nacre lustrous, valves typically intact, periostracum worn; animal probably dead less than one year),
weathered dead (no soft tissues, nacre very dull or chalky, valves may or may not be intact, periostracum worn; animal probably dead more than one year), or relic (portion of a shell and/or extremely worn and chalky, valves not intact, little or no periostracum; animal dead from many years to many decades).
Only freshly dead shells were quantified to provide an estimate of recent mortality at the time of the study.
Habitat. Within the location of each quantitative sample, depth and relative proportion of each substrate particle size (Wentworth Scale) were characterized.
The substrate assessment accounted for all substrate within the sample (not just the surface) and was visually estimated by the diver.
Depth was measured using a pneumophathometer attached to the diver lying flat on the riverbed. Water velocity and water chemistry (temperature, dissolved oxygen, pH, conductivity, and turbidity) were measured within 0.5 meter of the water surface and near the substrate surface at the upstream and downstream end of each site. GPS coordinates of these locations were recorded. Digital images of the site were recorded. In addition, all aquatic snails collected by all sampling techniques were identified and enumerated.

RESULTS The field survey was conducted between September 28 and 30, 2010. For all sampling methods combined, a total of 907 live unionid mussels (mean density = 1.19 mussels/m 2, S2 (variation) = 1.01; CPUE = 86.12; S2 = 44.47) representing 17 species were recorded during the survey (Table 1, page 6).
One federally endangered species, Lampsilis abrupta, was collected in the first transect of the Middle Site (M1).
Additionally, a federal candidate species, Plethobasus cyphyus, was found in the second transect of the Middle Site (M2) (Exhibit 3, page 18). Both individuals were measured for length, width and thickness, photographed, and returned by hand to the same 10-meter segment from which they were collected.
Fingernail clam (Musculium transversum) and Asian clam (Corbicula fluminea) were also observed during the mussel survey but were not quantified. Also encountered during the survey (all methods combined) were 503 live snails (mean density =
3.32 mussels/m2, S2 = 4.8; CPUE = 29.45, S2 =
28.0) representing two species.
Semi-Quantitative Sampling.: A total of 120, 10 square meter semi-quantitative samples were collected during the survey, resulting in the collection of 852 mussels.
Elliptio crassidens, Pleurobema cordatum, Cyclonaias tuberculata, and Quadrula pustulosa accounted for over 90 percent of all live mussels collected over all three reaches.
E. crassidens was the most commonly collected mussel in all three reaches.
The Pleurobema cordatum was the second-most commonly collected mussel at the Upstream Site and Middle Site while the Cyclonaias tuberculata was the second-most abundant mussel in the Downstream Site.
Densities and catch per unit effort (CPUE) observed during the semi-quantitative search throughout the project area averaged 0.71 mussels/square meter.
Mean CPUE was 86 mussels per hour.
Semi-quantitative densities ranged from 0 to 3.7 mussels/square meter and 0 to 396 mussels per hour, respectively (Table 2, pages 7 through 11). Total mussels and mean density observed per site are as follows:
Upstream Site, 175 mussels (mean density =
0.44 mussels/square meter [M2], S2 = 0.10);
Middle Site, 341 mussels (mean density = 0.85 mussels/m 2, S2 = 0.16); Downstream Site, 336 mussels (mean density = 0.84 mussels/m2, S2 =
0.28). When examining mussel abundance for each 10 meter transect across the Upstream, Middle, and Downstream Sites mussels were relatively evenly distributed along most transects, though trends were apparent along some transects (Table 2, pages 7 through 11).
At Upstream Sites U2 and U3 mussels were more abundant between 5 and 55 meters, while sites M1 and M3 at the Middle Sites exhibited higher densities from 55 to 105 meters. At Downstream Site D3 abundance peaked from 35 to 74 meters and again from 95 to 105 meters, while at D4 mussel abundance was highest from 75 to 105 meters (Exhibits 1, 3, and 5, pages 16, 18, and 20; Tables 2 and 3, pages 7 through 15). A detailed spreadsheet of all survey results and GPS coordinates for all sampling locations are located in Appendices A and B, respectively. A photo log of representative mussels for each species is contained in Appendix C. A total of 312 snails representing two species - Pleurocera canaliculata and Viviparus georgianus - were collected from semi-quantitative samples. Total snails and mean density observed per site were as follows:
Upstream Site, 128 snails (mean density = 0.32 snails/m2, S2 = 0.04), Middle Site, 173 snails (mean density = 0.43 snails/m 2, S2 =
0.06), Downstream Site, 11 snails (mean density
= 0.03 snails/m 2, S2 = 0.0).

Page 22 of 24 Mollusk Survey of the Tennessee River Near Watts Bar Nuclear Plant Rhea County, Tennessee Quantitative Sampling: A total of
- 120, 0.25 square meter quantitative samples were collected from the three sites.
Quantitative samples resulted in the collection of 50 live mussels representing six species. The two most commonly occurring species were Q. pustulosa and E. crassidens, which is similar to the results of the semi-quantitative sampling. The average mussel densities from a 100-meter transect using quantitative sampling ranged from 0.4 to 4.4 mussels/square meter with an average of 1.7 mussels/transect (Table 3, pages 11 through 15).
Total mussels and mean density observed per site were as follows: Upstream Site, 8 mussels (mean density =' 0.8 mussels/m 2, S2 = 0.21);
Middle Site, 24 mussels (mean density = 2.4 mussels/m2, S2 = 2.88); Downstream Site, 18 mussels (mean density = 1.8 mussels/m2, S2 =
0.69).
Quantitative sampling resulted in the identification of 188 snails representing two species. Total snails and mean density observed per site are as follows: Upstream Site, 82 snails (mean density = 8.2 snails/m2, S2 = 9.87); Middle Site, 101 snails (mean density = 10.1 snails/m 2, S2 = 17.64); Downstream Site, 18 snails (mean density = 0.5 snails/m2, s2 = 0.25). Sand was the most abundant substrate at the Downstream (49 percent) and Middle Site (61 percent), with gravel compromising another 28 percent and 23 percent, respectively. Gravel accounted for 64 percent of the Upstream Site.
Cobble was present in varying degrees at all three sites, silt only at the Downstream and Middle Site, and bedrock only at the Middle and Upstream Site.
Boulder, clay, and wood were also found at the Downstream Site.
Little variation in substrate was observed at the Upstream and Middle Site; however, at the Downstream Site the abundance of sand was limited to D1 and D2.
Clay (at transects D3 and D4) and boulder (at D4) accounted for an increased proportion of the substrate.
Average depth was similar at the Upstream and Downstream Sites, 16.4 feet (SD 2.9) and 15 feet (SD 2.3), respectively.
At the Middle Site, average depth was 20.3 (SD 4.1). Within sites, trends were similar with depths typically gradually increasing from near the bank to the channel.
Water chemistry (as measured with a Hydrolab turbidity meter) was relatively similar at each site, though several trends were noticed (Table 4, page 24).
DO gradually increased from upstream to downstream, starting at Ul with 4.49 mg/L and ending at D4 with 7.1 mg/L, while spC gradually decreased from 186.6 pS at Ul to 180.7 pS at D4. Also, pH levels were generally higher at the Middle and Downstream sites.
Turbidity was 0.0 throughout the project area.
While many weathered dead and relic shells were encountered, fresh dead shells were relatively few. Of the 907 live mussels recorded during the survey only 61 fresh dead mussels were encountered, yielding an estimated recent mortality rate of 6.3 percent. The fresh dead mussels were represented by the six most commonly encountered mussels E. crassidens, P cordatum, C. tuberculata, Q. pustulosa, P.
alatus, and E. lineolata.
No Dreissena polymorpha were encountered during the survey, though Corbicula fluminaea (Asian clams) were observed.
On average, the length of mussels collected in quantitative samples (47.9 millimeters) was nearly half that of mussels collected in semi-quantitative samples (98.1 millimeters), which characterizes the bias of semi-quantitative samplese to miss smaller and completely buried mussels.
Recruitment does appear to be occurring within the project area for some species. A total of 28 of the 907 individuals collected were estimated to be three years of age or younger.
These young individuals represented only 4 of the 17 observed species:
Leptodea fragilis, Obliquaria reflexa, Potamilus Prepared by: Third Rock Consultants, LLC November 2010 For: Tennessee Valley Authority
Page 23 of 24 Mollusk Survey of the Tennessee River Near Watts Bar Nuclear Plant Rhea County, Tennessee alatus, and Utterbackia imbilicis. Though snail lengths were not measured, various size classes were observed for both snail species.
A summary of age and length for each species is represented in Table 5, page 24.
Experimental Boulder Field: A total of three sites (two historic, one control) were sampled in or near the experimental boulder field. During the survey, only two historic sampling stations were re-located within the boulder field.
Sampling stations within the boulder field were determined by the presence of pieces of concrete embedded with steel rods (re-bar) driven into the river bottom. Divers were unable to re-locate all four pieces of re-bar that were originally placed to delineate boulder field sampling stations.
Sampling was conducted in these areas since no other areas with re-bar were located. A "control" site upstream of the survey area was also surveyed (Exhibits 1 and 2, pages 16 and 17).
While the last several quantitative samples were being processed on the boat, a 20-minute qualitative search was conducted through the boulder field to determine if any live mussels were present.
Quantitative sampling at three locations according to the boulder field sampling protocol failed to yield any mussels (mean density = 0.0 mussels/m 2, S2 = 0.0). The 20-minute qualitative sampling yielded a total of five live mussels (CPUE = 15 mussels/hour) and three snails (CPUE = 9 snails/hour) (Table 1, page 6; Exhibits 1 and 2, pages 16 and 17).
