Introduction Kingston Fossil Plant KIF placed into operation in 1955 withdraws condenser cooling water COW from Watts Bar Reservoir and is subject to compliance with the Tennessee Water Quality Act and the federal Clean Water Act CWA Section 316 b of the CWA requires the location design construction and capacity of cooling water intake structures to reflect the best technology available for minimizing adverse environmental impact Impingement mortality is a component of 316 b and is defined as an impact in which fish and or shelfish are trapped or impinged against an intake screen and often killed in the process In response to the Environmental Protection Agency EPA issuance of a 2004 rule for implementing Section 316 b a
rule subsequently suspended in 2007 and in accordance with the Proposal for Information Collection submitted to the Tennessee Department of Environment and Conservation TDEC in 2005 Tennessee Valley Authority TVA conducted impingement monitoring at KIF from November 2004 through November 2006 to assess the effects of impingement on the aquatic community of Watts Bar Reservoir This report presents impingement data collected from the CCW intake screens during 2004 2006 with comparisons to historical data collected during 1974 1978 Per an agreement reached in September 2001 with TDEC Division of Water Pollution Control TVA performs Reservoir Fish Assemblage Index RFAI Hickman and Brown 2002 sampling once every two years to demonstrate that KIF operation is not impacting the balanced indigenous population BIP TVA conducted these RFAI studies to evaluate fish communities in areas immediately upstream and downstream of KIF during the 2001 2003 and 2005 Scott 2006 The primary reason for gathering these data is to support the continuation of Section 316 a thermal variance for KIF However the RFAI monitoring also gives an indication of the overall impact of plant operations on the reservoir fish assemblage and benthic community including potential impacts from the plants cooling water intake Plant Description KIF is located on a peninsula formed by the Clinch and Emory River embayments of Watts Bar Reservoir approximately 4.4 km 2.7 miles above the confluence of the Clinch and Tennessee Rivers Figure 1 The final unit of the nine unit plant was placed in commercial operation December 2 1955 bringing the total capacity to 1,700 megawatts With an average summer water temperature of 23.90C 75.02 F Units 14 each require 6.6 m3s 241 cfs CCW and Units 59 each require 9.2 m3sec 324.8 cfs for an approximate plant total flow of 73.3 m3s 2,587 cfs for condenser cooling purposes The 18 condenser circulating water pumps each withdraw from separate suction pits Water enters the intake structure through trashracks constructed of vertical 1.59 cm 58 in steel bars with 9.21 cm 358 in openings The racks are periodically cleaned by a rake operated by the intake gantry crane Following the trashracks the CCW passes through the vertical traveling screens These are constructed of 0.6 X 3 m 2 X 10 ft screen panels of 12 gauge galvanized wire with 9.5 mm 38 in square openings The panels are fastened top to bottom to form an endless belt and attached to chains operating between sprockets at the bottom and drive sprockets supported on the intake deck Debris and fish collected on the traveling screens are washed off into a sluice trench that extends the length of the pumping station deck and empties into a 68.6 cm 27 in concrete pipe which conveys the screen backwash discharge underground in a southerly direction for 440 m 1,442 ft to empty into the CCW discharge basin 1
Intake Channel and Skimmer Wall An intake channel extends 1,372 m 4,500 ft from the pumping station to the original streambed of the Emory River in the Swan Pond Embayment of Watts Bar Reservoir Figure 1 A 126 m 413 ft long skimmer wall is positioned across the intake channel and extends 7.5 m 24 ft below the water surface The maximum depth of the intake channel is 12.5 m 40 ft The skimmer wall provides water at a substantially lower temperature to the plants condensers during the summer months A still further significant temperature reduction was obtained by the construction of a submerged dam or barrier on the Clinch River near kilometer 6.3 mile 3.9 downstream from the mouth of the Emory River The computed reduction in intake temperatures has been as much as 2.5 C 4.50F resulting in a substantial saving in fuel consumption at KIF The dam is built of quarry run limestone dumped into position from barges The 1.8 m 6 ft wide submerged dam crest is at an approximate elevation of 220 m 722 ft which ensures an adequate navigation depth at all times Methods Weekly impingement monitoring began on November 16 2004 and continued through November 6 2006 To simplify comparisons in this report data from November 16 2004 through November 8 2005 will be referred to as Year One and from November 16 2005 through November 6 2006 as Year Two To collect each sample the plant intake screens were rotated and washed on a prearranged schedule by the plant Assistant Unit Operator to remove all fish and debris After 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> screens were again rotated and washed with an Aquatic Monitoring and Management crew on site Fish and debris were collected in a catch basket constructed of 9.5 mm 38 in mesh at the end of the sluice pipe where the monitoring crew removed and processed the sample Fish were sorted from debris identified separated into 25 mm 1 in length classes enumerated and weighed Data were recorded by one member of the crew and checked and verified signed by the other for quality control Quality Assurance Quality Control procedures for impingement sampling TVA 2004 were followed to ensure samples were comparable with historical impingement mortality data Historical impingement sampling was conducted by TVA from August 1974 through April 1975 TVA 1976 Additional sampling was conducted three days per week by Oak Ridge National Laboratory personnel during the periods November 1976 through April 1977 and September 1977 through April 1978 TVA 1981 Moribund Dead Fish The majority of fish collected from a 24hr screen wash were dead when processed Incidental numbers of fish which appeared to have been dead for more than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> ie exhibiting pale gills cloudy eyes fungus or partial decomposition were not included in the sample Also during winter threadfin shad occasionally suffer die offs and are often impinged after death or in a moribund state Griffith and Tomljanovich 1975 Griffith 1978 If these die off incidents were observed they were documented to specify that either all or a portion of impinged threadfin shad during the sample period were due to cold shock and would not have been impinged otherwise Any fish collected alive were returned to the reservoir after processing 2
Data Analysis Impingement data from weekly 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> samples were extrapolated for each week to provide estimates of total fish impinged by week and an estimate for each year of the study In rare situations when less than a 24hr sample occurred data were normalized to 24 hrs Historical data collected during 1976 1978 TVA 1981 were collected during three days per week and weekly estimates were extrapolated accordingly For annual estimates data collected from September or November through April were extrapolated to annual totals impinged These annual estimates even though based on less than full year samples should be relatively comparable to current data presented here 2004 2006 since sampling covered the period of peak impingement To facilitate the implementation of and compliance with the EPA regulations for Section 316 b of the CWA prior to its suspension by EPA impingement losses of fish were evaluated by extrapolating the losses to equivalent reductions of adult fish or of biomass production available to predators In conformance with methods utilized by EPA in its Technical Development Documents in support of the Phase II Rule EPA 2004 EPRI formerly known as the Electric Power Research Institute has identified two models Barnthouse 2004 for extrapolating losses of fish eggs larvae and juveniles at intake structures to numbers or production of older fish The Equivalent Adult EA model quantifies entrainment and impingement losses in terms of the number of fish that would have survived to a given future age The Production Foregone PF model applies to forage fish species to quantify the loss from entrainment and impingement in terms of potential available forage for consumption by predators Required inputs to the models are site specific data on the distribution and abundance of fish populations vulnerable to entrainment and impingement TVA in turn also used these models to determine the biological liability of the COW intake structure Results and Discussion Numbers of fish collected by year and species are presented in Table 1 During Year One and Year Two of recent impingement monitoring 26,511 and 32,171 fish were collected respectively Table 1 The total number of species collected each year was similar with 30 species in Year One and 33 in Year Two Table 1 Total numbers estimated impinged by extrapolation by species and year for Year One and Year Two are presented in Table 2 Threadfin shad comprised 95 of the two year total followed by gizzard shad freshwater drum and channel catfish at 1 each Table 2
In Table 3 the estimated total fish impinged and percent of the annual total by month for both years are presented The estimated annual impingement extrapolated from weekly samples was 185,577 during Year One and 225,197 during Year Two Table 4 Peak impingement occurred during October through December at KIF Table 3 and Figure 2 The proportion of total fish impinged during October through December each year was 86 in Year One and 69 in Year Two A plot of daily 24hour average ambient intake water temperatures for KIF during each of the two years sampled is presented in Figure 3 Lower temperatures appear to be generally correlated with peak impingement as previously reported in numerous studies 3
EPRI 2005 Griffith and Tomljanovich 1975 Griffith 1978 McLean et al 1980 A recent study by Fost 2006 also indicated that cold stressed threadfin and gizzard shad can be classified as either impaired or moribund Impaired shad could recover if environmental conditions improved and would therefore not die if not impinged Moribund fish on the other hand are assumed to not be able to recover and die regardless of impingement Fosts data indicated that threadfin shad began to exhibit reduced or impaired swimming performance at 7.500 45.5F Figure 3 also presents average KIF intake temperatures from 1986 2006 for comparison While winter temperatures during both Year One and Year Two dropped below the Fost threshold these temperatures did not appear to coincide with specific impingement peaks in this study period Figure 2 Threadfin and or gizzard shad typically comprise over 90 of fish impinged on coolingwater intake screens of thermal power stations in the Southeastern U S EPRI 2005 They also comprise an average of 3556 of total fish biomass where they occur Jenkins 1967 No state or federal protected fish species were collected or are known to occur in the vicinity of KIF Application of the EA and PF models to the estimated total numbers of impinged fish indicated that 7,893 and 8,216 in Year One and Year Two respectively Table 4 would have been expected to survive to either harvestable EA sizeage or to provide forage PF This reduced number is considered the biological liability resulting from plant CCW impingement mortality based on the guidance developed for the now suspended 316 b regulations As part of TVAs Vital Signs Monitoring Program Scott 2006 resident fish communities were sampled in Watts Bar Reservoir upstream and downstream of KIF in 2001 2003 and 2005 Results indicated Good fish communities at both sites and TVA concluded that operations at KIF are not impacting the fish community of Watts Bar Reservoir Comparison with Historical Data Estimated impingement from historical sampling conducted during 1974 1978 including the extrapolated annual totals for number of fish impinged and the numbers estimated after EA and PF reduction are presented in Table 4 The extrapolated total for 1974 1975 was 335,076 for 1976 was 1,163,232 and for 1977 1978 was 2,881,039 Table 5 presents the percent composition by number of major species impinged during 1974 1978 and 2004 2006 Threadfin shad dominance was consistent at between 95 and 98 except during 1977 1978 when threadfin shad comprised only 48 of the total Peak impingement during October through January for the historical data Figure 4 agrees with that observed during 2004 2006 Figure 3 For the historical study it was concluded that based on data collected during 1974 1975 impingement of fish at KIF resulted in no adverse environmental impact TVA 1976 The Watts Bar Reservoir area experienced an unusually cold winter during 1976 1977 which caused a significant die off of threadfin shad from cold shock McLean et al 1979 1980 conducted studies at KIF to determine 1 the physical and biological causes of impingement of threadfin shad and 2 the effects of impingement on the threadfin shad population and on the threadfin shad predator population of Watts Bar Reservoir Impingement samples taken three times per week from midNovember 1976 through April 1977 produced an estimate of 240,000 threadfin shad impinged during this 51 2 month period The impingement rate for threadfin shad was strongly associated 4
with temperature Approximately 3,000 threadfin shad were impinged per day during November On December 7 water temperature decreased from 700 44.6 F to 400 39.20 F and the following day 42,000 threadfin were impinged Water temperature later decreased to 2.700 36.86 F which is below the lower lethal limit for threadfin shad Griffith and Tomljanovich 1975 and stressed shad were observed in large numbers in the KIF intake channel Dead and moribund threadfin shad were observed in shallow embayments and along the reservoir shoreline during this period The heated CCW discharge channel at KIF was the only place that healthy threadfin shad were observed throughout the winter Schneider and Tuberville 1981 Despite the obvious significant mortality in the threadfin shad population that was estimated at 95 in Watts Bar Reservoir more than twice as many threadfin shad were impinged the following winter 1977 1978 From late September 1977 through the end of April 1978 an estimated 560,000 threadfin shad were impinged at KIF McLean et al 1980 As observed during the previous year almost all threadfin shad were impinged before January 25 Total numbers of all fish estimated impinged during the winter of 1977 1978 2,881,039 were also higher Table 4 While the percent composition of threadfin shad was lower 48 during this period skipjack herring composition 28 as well as gizzard shad at 22 was significantly higher during 1977 1978 Table 5 The fact that threadfin shad demonstrated the ability to rebound from a reservoir wide non plant induced mortality cold stress indicates that impingement mortality at KIF does not represent an adverse impact to the threadfin shad population of Watts Bar Reservoir Summary and Conclusions Impingement of fish by the KIF COW was monitored during 2004 2006 and compared with historical data collected during 1974 1978 Total numbers of fish estimated to be impinged annually were lower during 2004 2006 than during 1974 1978 The average number estimated to be impinged during 2004 2006 two years was 205,387 compared to 1,459,782 per year during 1974 1978 Annual fish impingement totals were noticeably lower during 2005 2006 than during historical monitoring periods 1974 1978 RFAI scores in 2003 and 2005 of 43 and 44 for downstream and upstream samples respectively indicated good fish communities at both sites Resident fish communities at these locations reached 71.1 and 73.3 of their potential scores for downstream and upstream sites respectively All the score averages for the Tennessee River stations in the vicinity of KIF indicate Good fish communities and the nearest downstream Watts Bar Reservoir average met the adjusted 70 screening criteria for designation as BIP These factors as described above provide evidence of a balanced and healthy fish community and indicate that the KIF COW intake has not adversely impacted the Watts Bar Reservoir biota 5
