I l BIOLOGICAL CONCLUSIONS l' I
- 1. The concentrations of a majority of the water quality parameters I associated with ;: nogical studies varied seasonally; however, no differences tha', would have biological significance were detected between I upstream control and downstream discharge sites.
- 2. Variations in phytoplankton and zooplankton densities occurred over the course of the study; however, there were no qualitative or quantitative l
changes in plankton communities of the adjacent Chattahoochee River that were attributable to the operation of the Farley Nuclear Plant intake.
- 3. Larval fish studies in the vicinity of the plant failed to indicate any-significant effects of plant intake operation on larval fish in the
{ Chattahoochee River.
- 4. Impingement studies at the Farley Nuclear Plant intake indicated low impingement rates were occurring relative to game and comercial species.
Impingement rates for other species were also considered insignificant relative to any effect on fish populations existing in the Chattahoochee River. ,I
- 5. The results of biological studies of the Chattahoochee River near Farley riuclear Plant failed to indicate any significant changes in biological I communities which could be associated with intake operation.

I STUDY AREA 5 The section of tne Chattahoochee River (CR) included in this study ex+. ended from kiver Mile 45.2 (CRM 45.2) downstream to River Mile 41.0 (CRM 41,0) (Fig. 1). The Joseph M. Farley Nuclear Plant is located on the banks of the Chattahocchee River between CRM 43 and 44. Sample station 1, located at CRM 45, is 1.5 miles below Andrews Lock and Dam and a;mroximately one mile aDove the Farley Plant. Sample station 2 is located in the river water intake canal at CRM 43.8, Station 3 extended from the discharge structure to 1/2 mile downstream (CRM 43.0-43.5), and Station 4 is located l in tne Smith's Bend section of the river (CRM 41.0-41.5).
~
Plankton and water samples were collected from depths of 0.3,1, 2, 4 - and B meters (when river depth allowed), and larval fish samples were collected from depths of 1.5, 3.0 and 4.5 meters (when river depth allowed). This section of the Chat.-hoochee River is subject to a large degree of sand sedimentation so that watr- depth was seldom more than 4-6 meters on most g dates. IE ll I E I I I i -

I WATER STUDIES I Sampling Procedures Samples were collected about the middle of each month beginning in August, 1981 and continuing through January, 1983 for a total of eighteen sampling dates. Water quality variables measured at each site and depth included temperature and dissolved oxygen (DO). These measurements were made I- using a YS1 Model 51A oxygen meter. Secchi disc visibility was also measured at each station. Water samples for chlorophyll analyses were collected with a submersible pump and hose and stored in Nalgene plastic containers. All water samples were held in ice" chests for transport back to laboratory facilities
- I located at Auburn University, Auburn, Alabama. For the analyses of chlorophyll a_, b and c_, a 100 ml aliquot of water from each depth was filtered onto a 0.45 y pore size, Millipore filter pad, macerated in a tissue grinder and the pigments extracted in 90% acetene. Chlorophyll concentrations were estimated using the Trichromatic Method (APHA et el. 1980).
I Water samples for plankton analyses were also collected with a submersible pump and hose apparatus. For phytoplankton analysis, a 500 ml water sample was collected at each depth and placed in a one liter flat-bottomed Nalgene jar containing 18 ml of merthiolate preserving solution. Zooplankton samples were collected at each depth by pumping 80 liters of water through a I standard Wisconsin style (80 u mesh) plankton net. Zooplankters were washed from the net bucket into 100 ml Nalgene plastic containers and preserved in Si fomalin. Plankton samples were counted and identified using Sedgwick-Raf ter counting chambers following the procedures recommended by Weber (1973). I 4
I I. Plankton data reported by station and depth include standing crops for phytoplankton and zooplankton. By station, data included chlorophyll concentrations, dominant plankters and for zooplankton communities, species diversity (3) and equitability (e) values. , I I I I I I I I - I I

I RESULTS AND DISCL'SSION Water Variables Secchi Disc Readings Light transmission through the water was measured by Secchi disc . readings at each station. Visibility as measured by the Secchi disc provides an estimate of turbidity. When the turbidity in the river is not due primarily to suspended sediment, Secchi disc readings correlate well with phy-toplankton density. Summaries of the Secchi disc visibility data are provided in Table 1. The limited visibility of waters near the Farley Nuclear Plant result from two primary sources: 1) the high degree of turbulence in the river as a result of hydroelectric power generation through Walter F. George Dam and the regeneration of this turbulence as the water passes through Andrews Dam;
- 2) the waters relea>ed from both dams contain higher standing crops of phytoplankton (which will reduce visibility giving lower Secchi disc readings) than would normally be encountered in a river transporting as much sediment as the Chattahoochee.
There is no evidence from visibility data provided by the Secchi disc readings that the intake or discharge from the Farley Nuclear Plant caused any change in the sediment or phytoplankton load of the waters in this reach of the Chattahoochee River. Temperature and Dissolved Oxygen (D0) Temperature and DO content in the water column at each station are shown in Tables 2 and 3. Additionally, temperature profiles of the water column at each station are provided on Figures 3-20 and 22-36 of plankton standing crops. Thes3 data show the seasonal variability expected for water temperatur<s, but no indication of significant variations between stations I l l LI J Table 1.

I or depths on a given sampling date. There was no evidence from the study that indicated any change in temperature or 00 concentration associated with the intake or discharge from the Farley Nuclear Plant. I Sumary of Water Variables The watershed upstream from the stretch of the Chattahoochee River studied provides an excess sediment load (primarily sand) to the water. Deposition and erosion of the sandy river bottom in the region of the Farley Nuclear Plant is a continuous process that resulted in decreasing water depths following channel dredging operations. Because of the close proximity l of the nuclear plant to Andrews Dam and Walter F. George Dam, this reach of the river is essentially like a modified tailrace below a major river - impoundment. Water temperature and dissolved oxygen content measured on each sampling trip indicated that within this stretch of the river these water quality variables were favorable for the support of aquatic life. The waters discharged by the Farley Nuclear Plant were at no time observed to appreciably alter temperature or dissolved oxygen values. Secchi disc visibility of the water at each station on all dates sampled also indicated no unfavorable conditions for the support of aquatic l ccmmuni ties. 1 I I I I Plankton studies Phytoplankton Mean phytoplankton abundance by group (algal division) and chlorophyli a concentrations for the 18 month study are shown in Figure 2. The vertical I - distribution of phytoplankton in the water column, temperature profiles and mean chlorophyll a, b and c concentrations for each station and date are shown in Figures 3 through 20. Data on numerical dominance by phytoplankton group (algal division) and species appear in Tables 4 and 5, respectively. Mean chlorophyll a, values ranged from a low of 2.6 mg/m3in September of 1982 to a high of 12.1 mg/1 3 in October of 1981 (Fig. 2). Winter and spring phytoplankton communities were dominated by diatoms (Chrysophyta) mostly, except for one date when green algae (Chlorophyta) were dominant (Fig. 2 and Table 4). The diatoms were mostly various unidentified pennate and centric diatoms (Table 5). The summer and I fall samples were dominated by various green and blue-green (Cyanophyta) algae. During the warm months of July, August and September 1982, olue-green blooms dominate phytoplankton (Fig. 2). The phytoplankton standing crops in this reach of the Chattahoochee River are higher than similar riverine habitats around Alabama. This is attributable to the influence a' pools formed by Walter F. I George Lock and Dam and Columbia Lock and Dam, both located upstream from the Farley Nuclear Plant. The vertical distribution of phytoplankters in the water column was relatively uni form. Between stations the phytoplankton distribution patterns, densities and chlorophyll concentrations were remarkedly similar on any given date (Figs. 3-20). I I

I The most abundant and frequently encountered diatoms were Melosira granulata, M. varians, M. distans. Cyclotella spp. and various unidentified pennate diatoms (Table 5). Dominant green algae included Chlamydomonas sp., I severa*. species of Scencdesmus and Ankistrodesmus convolutu h Blue-green algae were dominated by Spirulina laxa, Radhidiopsis sp., Oscillatoria angustissima, Lyngbya sp. and Gomphosphaeria sp. (Table 5). Seasonal shif ts in dominance were observed but no biologically significant differences between stations were detected on any given date.

l Zooplankton ( Zooplankton densities (by group) for the 18-month study appear in Figure 21. The vertical distribution of zooplankters in the water column and tenperature profile for each station and date appear in Figures 22 through 36. The three numerically dominant taxa in each zooplankton group for each station and date appear in Table 6. Mean density, numbers of taxa, diversity IB) and equitability (e) for zooplankton collections on each date appear in Table 7. Rotifers dominated zooplankten communities on all dates with cladoceran and copepod density usually much lower (Fig. 21). Zooplankton density ranged from a low of 51 organisms / liter during October 1982 to a high of 560 organisms / liter the following month (November). The data in Figure 21 show that rotifer density exhibited much greater fluctuation during the 18-month study than the other two groups. Based on results of plankton studies conducted in comparable streams in Alabama, zooplankton standing crops in this reach of the Chattahoochee River were considerably higher than expected. This again was apparently due to the influence of the pools above Walter F. George and Columbia Lock and Dam upstream from the study area. The vertical distribution of zooplankters at each station reflects the tendency of these organisms to migrate up and down in the water column (Figs. 22-36). A comparison of the data in these figures generally shows that rotifers were more uniformly distributed in the water column than copepods and cladocerans. Both copepods and cladocerans have a greater tendency to migrate vertically than do rotifers, often occurring in greater numbers well below the surface of the water. Patterns of distribution varied considerably betwen dates but variations between staticns on any given date were minimal. The most abundant and frequently occurring zooplankters in each major group were:
I , rotifers--Keratella cochlearis, Polyarthra spp., Synchaeta spp, and k Brachionus,spp.; copepods--imature copepods and Cyclops spp.; cladocerans--Bosmina longirostris, Bosminopsis deitersi, Diaphanosoma 500. and Ceriodaphnia lacustris (Table 6). Diversity (6) and equitability (e) indices were strikingly similar I at all stations on any given date (Table 7). The variations in 8 and e between dates were apparently due to seasonal changes in environmental conditions. Diversity of a hypothetical community consisting of 100 organisms evenly divided among ten taxa would be a 8 = 3.32 and an e = 1.43, whereas a comunity of 100 organisms with 90 in one taxon and 10 in the other would have a 8 = 0.47 and an e = 0.75. Based on the results of this study, there appears to be no evidence l that the operation of the Farley Nuclear Plant has had measurabit adverse effects on zooplankton comunities in this reach of the Chattahoochee River.

I Larval Fish Fishes in the Chattahoochee River near Farley Nuclear Plant can be classified generally as warm-water species which will spawn anywhere the habitat is suitable. Studies to determine the densities and types of larvae in the vicinity of the plant were conducted every two weeks during the period March through June,1982. Larval fish collected during the study were obtained from four sample areas in the vicinity of the plant. Sample stations included: (1) an upstream station located approximately 0.9 miles above the plant intake; (2) an intake canal sample station; (3) a discharge sample station; and (4) a downstream station located approximately two miles below the plant discharge. Samples were collected at depths of 1.5, 3.0 and 4.5 meters. (Sampling at the 4.5 meter depth was dependent upon sufficient water depth). Samples were obtained by towing a plankton net with attached flowmeter and represent larvae obtained from approximately 100 cubic meters of water. Larval fish densities were computed for each sample area and sample date during the study period. Table 8 provides the number of cubic meters sampled, total larvae per cubic meter, and the taxonomic identification of larvae for each sample area and depth. Table B shows that the Clupeidae (herring family), which includes the shad, represented the dominant taxonomic group in all sample areas during the study. The groups less represented during the study were the Castostomidae, Centrarchidae and Cyprinidae. A total of 184 larvae were collected during the 1982 study period. The number and percent of the total represented by each of the previously mentioned groups is as follows: Clupeidae, 175/95.1%; Catastomidae, 2/1.1".; Centrarchidae, 4/2.2%; Cyprinidae 1/0.5%; and Unidentified, 2/1.1*.. An attempt to describe the distribution of larvae in each of the four sample areas, based on taxonomic differences, could only be conjectural based on the numbers and percentages listed above.

I I, The low densities of non-Clupeids is probably due to lack of suitable spawning habitat in the vicinity of the plant. The extremely unstable sand and gravel bottom of the Chattahoochee River in the vicinity of the plant and the 0.6 to 0.9 meter per second velocities resulting from a narrow river ^ channel and operation of Andrews Dam (located approximately 0.5 miles above the upstream sample station) make this portion of the river under study psor spawning habitat, especially for those species which build nests or require semi-lentic spawning conditions. The average number of larvae collected from each sample area, ., during each sample period, is presented in Table 9. Temperature and dissolved oxygen data collected during each of the larval fish sample periods are presented in Table 10. . . Larval fish studies conducted in the Chattahoochee River near Farley Nuclear Plant during 1982 indicated poor spawning success for fishes other than the Clupeidae, Unstable bottom conditions resulting from high , river velocities and associated operation of Andrews Lock and Dam are expected to be the primary contributing factors for icw larval densities. Data collected during the study did not indicate that any differences among the three areas could be attributed to plant operation, but were closely tied to variations in natural environmental conditions in that portion of the river under study. The results of the 1982 larval fish study, which was designed to evaluate the effects of two unit operation at the Farley Nuclear Plant, failed to indicate any significant effects of plant operation on larval fish in the Chattahoochee River.

I 1r91ngement Studies Impingement monitoring at Farley Nuclear Plant began on February 18, 1982 and extended through January 17, 1983. Fish and other aquatic organisms impinged on intake screens were collected for one continuous 24-hour period every two weeks during the study. Organisms impinged during the 24-hour sample periods were obtained by passing the d effluent from the screen wash system through a collection basket. Fish l collected during the study were identified and individually counted, weighed and measured. The weights of fish were obtained as previously noted, with tne exception of small shad (Dorosoma spp), which were weighed in aggregate in order to increase the occuracy of weight determinations for this species. Impingement data were collected on 26 sample periods during the 12-month study. Impingement data collected during the study are presented in Table 11, which includes the number and weight of each species collected during each of the 24-hour sample periods. Impingement monitoring at Farley Nuclear Plant resulted in the collection of 14,103 aquatic organisms (see totals in Table 11). The clam Corbicula fluminea and the Clupidae hncluding gizzard and threadfin shad) were the most numerous of the orgarisms collected. The Corbicula and shad accounted for 6.49% and 91.50%, respectively, of the total organisms collected during the study. Thus, these two groups, collectively, represented 97.99% of all organisms collected , during the 12-month study. Aquatic organisms collected during the impingement study were l divided into three general categories which included game species, comercial species, and other species. Organisms collected during the impingement I studies, and classified as previously described, are presented in Table 12. The total number and weight of each species collected are presented, as well as the estimated daily and annual impingement rates for each species identified. The estimateo annual impingement rates for game, comercial,
~ - .
I other fish species, and Corbicula (see Table 12) were detennined to be 723; 2383; 166,756 and 12,565, respectively. The estimated annual impingement rate e of 166,756, as shown for the classification of other fish species, includes ! an impingement esticate of 166,212 for the Clupeidae. Thus, the estimated annual impingement rate for all non-Clupeid spe:tes of fish is 3,650. The estimated annual weight of fish impinged on intake screens as determined to l be 50.27 pounds (22.80 kg.) for game species, 156.06 pounds (70.79 kg.) for commercial species, 1390.66 pounds (630.80 kg.) for other fish species, and 33.22 pounds (15.07 kg.) for Corbicula. The Clupeidae account for 1353.65 pounds (614.02 kg.), thus the estimated annual impingement rate for non-Clupeid species of fish is 243.34 pounds (110.38 kg.). The estimated annual weight for all organisms impinged on intake screens was determined to be 1630.21 pounds - (739.46 mg.). The distribution of fishes and shellfish over the 26 sample periods is presented in Figure 37. Most of the fish collected during the impingement study occurred during the late winter and early sprin5 The impingement of fish during this period has been seen at other power plants throughout the State and is thought to be related to increased movement of fishes associated with feeding and spawning behavior. Impingement rat.es for C_orbicula were relatively constant throughout the study with the exception of the period late June to early July, during which significantly larger nun.bers were observed. Table 13 and Figure 38 present the minimum and maximum rates of water withdrawal which could have occurred through the in',ake system during each of the impingement sample periods. Average flow rates for each 24-hour period could not be obtained since available information on pump operation was limited to the number of pumps running in continuous mode and the number of pumps set in the automatic mode. Thus, tne data in Table 13 shows flows known to cccur (minimum flows) and flows which could have occurred (maximum I I< I W 6 m c s w

I flows), based on the number of pumps set on automatic. The rate of water withdrawal did not appear to be relatee to impingement rates for fish, with the peak impingement rates occurring during a period of relatively low intake flow rates. The peak impingement rates for Corbicula did occur during a period of high flow rates. However, taking into consideration the relatively low rate of impingement for Corbicula during other periods that had equally high rates of flow, this peak was assumed to be coincidental. The results of impingement studies at the Farley Nuclear Plant indicate that the removal of fish and other aquatic organisms from the Chattahoochee River is sufficiently low that no significant harm to aquatic communities is expected to occur. Impingement rates for game species were determined to be extremely low. The estimated daily impingement rate f,or game species of 2.17 is less than 5?. of the daily creel limit per fishermen for sunfish, as set by the Alabama Department of Conservation & Natural Resources. The impingement rate for commercial species was also considered to be low, with an estimated daily rate of 7.16 fish. Biological studies conducted near Farley Nuclear Plant prior to and during the first year of operation of Unit #1 indicated that threadfin shad, gizzard shad, and Corbicula represent the majority of aquatic organisms living in the vicinity of the plant. Thus, impingement rates for shad and Corbicula, while appearing relatively high in comparison to impingement rates for other groups, are not considered sufficiently high to cause any detrimental effects to populations of these species.

l I BIOLOGICAL CONCLUSIONS
- 1. An analysis of macroinvertebrate populations, using density, diversity and equitability values, did not indicate any significant differences l in populations of these organisms which could be contributed to the operation of Farley Nuclear Plant.
- 2. The concentrations of a majority of the water quality parameters associated with biological studies varied seasonally; however, no differences that would have biological significance were detected between upstream control and downstream discharge sites.
- 3. Variations in phytoplankton and zooplankton densities occurred over the course of the study; however, there were no qualitative or quantitative changes in plankton communities of the adjacent Chattahooctiee I River that were attributable to the operation of the Farley Nuclear Plant.
- 4. Larval fish studies in the vicinity of the plant failed to indicate any noticeable changes in larval fish densities or spawning periods during tne four-year study.
- 5. Studies of adult fish populations, using n lative abundance and condition values, did not indicate any major changes in fish populations had occurred as a result of the operation of Farley Nuclear Plant.
- 6. Impingement studies at the Farley Nuclear Plant intake indicated low l impingement rates were on.urring relative to game and commercial species.
Impingement rates for other species were also considered insignificant relative to any effect a fish populations existing in the Chattahoochee River.
- 7. The results of the four-year biological study of the Chattahoochee River near Farley Nuclear Flant failed to indicate any significant changes in biological communities which could be associated with plant operation.

W. / I Results and Discussions Introduct y Mennoring of aquatic connunities in the Chattahoochee River near Farley Nuclear Plant was begun in 1975 in accordance with conditions of tne NRC FES-OL for the Farley Nuclear Plant. The program, as described below, provided for the Jampling of aquatic comunities in the Chattahoochee River and the comparison of data collected curing pre-operational monitoring with data collected during operational nonitorit.g. The comparison of data collected during pre-operational monitoring with date collected during operational nonitoring provided the basis for evaluating the impact of the operation of Farley Nuclear Plant on the aquatic environment. The change , from pre-operational to operational monitoring is based on the December 1, 1977 com creialization of Unit 1. Macroinvertebrate Studies An aquatic macroinvertebrate sampling program was initiated on the Chattshoochee River near Farley Nuclear Plant in June,1975. Macroinvertebrate populations were assessed using Hester-Dendy multiple-plate samplers (Weber 1973)l . Samples were taken quarterly frnm both the east and west banks of the river at these sample stations. Macroinvertebrate sample areas included: (1) an upstream sample area lecated approximately 1.2 miles above the plant discharge, (2) a discharge sample area, and (3) a downstreem sample area located approximately two miles below the plant discharge. Macroinvertebrate studies were conducted over a period of forty-two months and included fifteen sample periods. Studies were begun in June,1975 and terminated in November,1978. Macroinvertebrate studies conducted during tht, previously mentioneC period provided information ralative to the types 1 Weber, Cernelius I, 1973. BioloA.g4-7g0prd Fi U.S. E.P.A., Cincinnati. E.P.

4 and densities of organisms present in er-h of the three sample breas. Tabins 1 through 4 list the macroinvertebrate taxa identified from each s sampic area during each sample period, as well as the numbcr of organisms collected per square meter of sr.mpler. Data presented in the previously , referenced tables does not indicate any noticeable differences in dominant taxa among the three sample areas during the study. Macroinvertebrate population densities (number /m2) changed considerably from season to season and year to year in all sampla areas, as determined from multiple-plate samples. Table 5 is a summary of macroinvertebrate densities for each sample area during each of the sample periods, it is obvious from the data presented in the pre',iously referenced l table that macroinvertebrate densities in all sample areas were lower in the spring and winter sample period 2 than in the sumer and fall sample periods during each of the study years. Peak macroinvertebrate densities occurred in all sample areas during the fall sample period of each year. Figure 1 is a graphical presentation of average macroinvertebrate densities in each l sc.mple area during each sample period. While information presented in Figure 1 does not indicate equa', densities in each samnle area during the study, it does indicate that fluctuations in population densities followed the same trend during each sample year. Yearly average population densities are shown for each sample area and year in Figure 2. A statistical evaluation of macroinvertebrate densities was conducted to determine if any differences existed between sample areas during each sample year. The results of 3 " student's t" test did not indicate any significant differences in macroinvertebrate densities among the three sample area, when computed for each sample year, using an 80% confidence limit. A comparison of sample areas, using data from all sample years. L -

I indice.ted that the discharge sample area had significantly (80% C.L.) higher population densities than the upstream and downstream sample areas. I Macroinvertebrate diversity and equitability values (ibid., g Weber, 1973) were calculated from data collected during each of the sample periods. Diversity and equitability values, computed for each sample area, are presented in Tables 6 through 9. The diversity and equitability values computed from multiple-plate data indicate similar macroinvertebrate populations in each of the three se>nple areas. Average diversity values for the upstream, discharge and downstream sample areas during the four-year j study were 1.91,1.88 and 1.91, respectively. Figure 3 is a graphical presentation of population diversity values computed for each sample period during the study. While diversities were not the same in eacn of the three areas, fluctuations within each sample area followed the same general trend during the study. A comparison of diversities using a " student's "t" test indicated significant differences among the three areas within sample years. Diversity values computed for the downstream sample area were found to be i significantly greater (90% C.L.) than values computed for the upstream area during 1977. Significant differences detected during the 1978 sample year included: (1) diversities in the discharge area greater than diversities I in the downstream area (95% C.L.) and (2) diversities in the upstream area greater than diversities in the downstream area (90% C.L.). No other l significant differences (90% C.L.) were detected among the threc sample areas during each of the sample years. An analysis of diversity values using data from all sample years failed to indicate any significant difference among the three areas, even at the 60% confidence level. Equitability values computed from data collected at each sample area are presented in Tables 6 through 9. Macroinvertebrate equitability values varied ennsiderably from sea 3cn to season in each of the three sample areas. However, fluctuation in each sample area (as depicted in Figure 4 ) l

followed the sarre g2neral trend during the four-year study. Equitability values computed for each of the three sample areas were compared using the
" student's t" test to detennine if any tignificant differences existed within sample years. The results of the previously mentioned test indicated only one significant difference an,ong the three sample areas.
Equitability values computed for the upstream sample area were found to be significantly greater (i,0% C.L.) than values computed for the discharge area daring the 1978 sample year. An analysis of equitability values using data from all sample periods indicated significantly greater (95% C.L.) values occurred in the upstream area as compared to the discharge area. Conclusions The collection of aquatic _ macroinvertebrates from three sample stations on the Chattahoochee River near Farley Nuclear Plant indicated considerable fluctuations in population parameters throughout the four-year rtudy. Differences in macroinvertebrate density, diversity and equitability values betveen the three stations, during the four s. ample years, were few and sporatic i.' occurrence. Differences between the three areas, based on quarterly values obtained from all sample years, indicated significantly higher densities (80% C.L.) in the dischcrge area as compared to the upstream and downstream sample areas. The upstream sample area had significantly higher (95% C.L.) equitability values than the discharge sample area when values for all sample periods were compared. It is concluded that differentes in density, diversity and equitability values associated with macroinvertebrate populations in the three sample areas do not indicate any change in community structure between the three sample areas during the four-year study. However, the data collected does indicate a seasanal fluctuation in comunity structure that is shared by all sample areas. i 1 _Sampitg and Analytical Procedures for Water Quality Studies.

l I l I Light Tranemission in Waters I Light transmission into water at all sampling stations on all sampling dates was measured by secchi disc readings and on occasima by determination of the point of 99 percent extinction of surfact light intensity. Summaries of I the secchi disc visibility data are given in Table 10 . l It is evident from these data that visibility into the water showed slight variations from station to station on a given sampling date, but variations in I the visibility into the water between sampling dates was much mc,re pronounced. l The limited visibliity into waters in this reach of the river was partially the result of the high degree of turbulence in river waters as a result of genera 4 I tion releases by Walter F. George Dam and the regercration of this turbulence as thesa released waters passed through Andrews Dam. Plus the fact that nor-mal water depths were relatively shallow throughout the sample area (ranging I from 4 to 6 int.ters on a majority of sampling dates). It is also noted that the waters released by the Walter F. George Dam contained more phytoplankton (which will reduce visibility into water) than would normally be encountered in a Southeastern river. Further evidence that turbidity of the Chattahoochee 111ver waters within this reach of the river varied only slightly betwen stations on a given sampling day, but varied significantly between sampling dates was provided by measure-ments of Jackson Turbidity Units (JTU'c) and suspended solids in the laboratory. These measurement data are summarized in Tables 11 & 12 , respectively, and are in general agreement with the Secchi disc visibility information. t

From these data summaries it is evident that TOC, particulate C, and total C concentrations in these river waters varied within very limited ranges - I between r'stions on a given sampling date, but wider variations existed between different sampling dates. No real evidence exists in these data accumulated between May,1975 and I December,1978 that indler.ted real differences in concentrations of these C forms associated with stations on a given arJaple date. Thus, there is no evi-dence of any change in C concentration in the Chattahoochee River that can be attributed to the discharge from the Farley Nuclear Plant. Information on the ash-free (organic matter) content in these water samples is given In Table 16 . I I l' l -u. 7

hiacro- and Micronutrients in Source and Receiving Bodies of Water. ( The concentration of ortho and ortho + particulate phosphorus and total nitrogen (including ammonia, nitrite, and nitrate forms)in samples of water collected on each sampling date are given in Tables 17 ,18, and 19 . It is noted that for a majority of the sampling period the total nitrogen concentration was adequate to excessive while the ortho phosphorus concentration appeared to l be limiting for maintaining anything greater than a moderate population of phyto-plankton. The 24-hour flows of ortho and ortho + particulate phosphorus for each sampling date are given in Table 20 Dat- on ammonia N and nitrate N concentrations at this site z.re given in Tables 21 and 22 - The micrountrients (including calcium, magnesium, potassium, iron, and
. manganese) concentratiocs in the filtered waters frem the Chattahoochee River and in the removed suspended matter on varicus sampling dates are given in Table 23 The presence of moderate concentrations of calcium and iron (in-cluding those quantities found in suspended matter) in these waters was probably responsible for the reduced quantities of phosphorus generally present. All elements included in the macronutrient list were present in sufficient quantities at all stations and sampling dates to support a greater population of phytoplankton than was found to exist.
Concentrations of some heavy metals (including zinc, chromium, cadmium, copper, lead, and nickel) in water samples from the Chattahoochee River at Far-ley Nuclear Plant are given in Table 24 None of these elements were present in sufficient concentrations to exert any detrimental effects upon the biological l l community.

5 lI '( Other Water Quality Parameters I Temperature and dissolved oxygen (D.O.) content in the water column on given sampling dates are shown in Tables 25 & 26 . These data indicate that while water temperatures varied seasonally, there was no evidence of significant I variations between stations and depths on a given sampling date. No evidence war gathered in this study that indicated any change in temperature or D.O. concen-tration a rociated with the discharge from the Farley Faclear Plant. I Data on other water qualf ty parameters, including pH, specific conductanm, free carbon dioxide, total alkalinity, sulfates, and chlorides are summarized in Tables 27 through 32. Variations in concentrations of each of these para-I meters from each station on each sampling date are negligile. Variations be-tween sampling dates are more evident, but are insignificant so far as indicating any drastic change in the aquatic habitat that might be associated with the Farley Nuclear Plant's discharge water.

,( Summary Discussion I Sampling of the Chatteoochee River in the environ of the Parley Nuclear Plant was an exercise in sampling a modified tailra?.e below a major river im-poundment. Due to the terreFtrial makeup of the upstream watershed there was an excessive sitt load (primarily sand) transported into the sampling arel. Con-sequently, the deposition onto and shifting of the sand bottom in this stretch of the river was a continuous process that resulted in decreasing water depths fol-lowing the yearly navigation channel dredging operation.
Water temperature and dissolved oxyeen concent.st on dsterminations, made on each sampling trip, indicated that within this stretch o. the river these ' water quality parameters were always favorable for the support d aquatic life. The waters discharged by the Farley Nuclear Plant at no time were observed to alter these favorable temperature and D.O conditions. Other water quality parameters, such as pH, free CO 2, speciuc conductance, etc. were also invorable for the support of aquatic life throughout the course of this study. There was no evidence that the waters discharged by the Farley Nuclear
.I Plant altered any of the water quality parameters that were under observation.
I I I I I
I II l s Sampling and Analytical Procedures for Plankton Studies I Location of phyto- and zooplankton sampling stations and depths and sam-pling dates were the same as those described for water quality analyses (page 18 ). Plankton samples were taken between 1200 and 1400 hr on most sampling dates. A submersible pump and hose apparat.us was used to collect water at the various sample depths. Forty liter) of roter were passed through a standard Wisconsin style (80 micron mesh) plankton net and all zooplankters ware washed from the net bucket into a 100 ml Nalgene container and preserved in a 5% for-malin solution. For phytoplankton analyses, a 500 ml water sample was tr. ken at each depth snd transferred to a 1-1 flat-bottomed Nalgene jar containing 18 ' ml of a merthiolate preserving solution. Samples were transported to labora-tory facilities located at Auburn University, Auburn, Alabama, and analyzed as outlined in Table 33. Starting in 1976, chlorophyll concentrations were men-sured in waters collected at each station and depth on all sampling dates except 22 April and 25 August 1976. Phytoplankters from a 200 ml aliquot of reservoir water were collected on 0.45m pore size Millipore filters, macerated in a tissue grinder, and the pigments extracted in 90% acetone. The chlorophyll content was estimated using the Trichromatic Method (Table 33 ). I I I I l

Phytoplankton L ~ Variations in phytoplankton numbers and chlorophyll concentrations were pronounced at indicated in Figures 6 and 7 . Winter and spring phytoplank-ton communities were dominated by centric diatoms and summer and fall com-munities by various green and blue-green algae. Mean chlorophyll a concentra-3 tions ranged from a low of 2.3 mg/m3 15 February 1978 to a high of 45,9 mg/m 10 February 1977. Mean phytoplankton densities ranged from a low of 241 organ-1sms/ml 15 Febnlary 1978 to a high of 37,638 organisms /ml 25 February 1976. High turbidities caused by suspended inorganic particles depressed phytoplank-ton standing crops in May 1975 (40.3 JTU's), February 1976 (41.4 .1TU's), and
- March '.978 (33.1 JTU's) (Table 1I and Figures 6 and 7 ). Phytoplankton standing crops in this reach of the Chattahoochee River are abnormally high when compared to data from other plankton community studies conducted in similar habitats. This is attributable to the influence of the two upstrcam impoendments l
(Walter F. George Lake and Columbia Lock and Dam) on the r+ndy area. Vertical distribution of phytoplarkters in the water column, temperature profiles and mean chlorophyll a_, b ar 3 c_ concentrations at each sampling site I are illustrated in Figures 8 throut;h 34. Phytoplankters were uniformly dispersed through the water column and the distributton patterns, organism den-sities and chlorophyll concentrations at the various stations were simliar on any given sampling date. 4

I Data on numerical dominacce by phytoplankton group (algal Division) ap-pear in Table 34. Diatomp were the dominant organisms on 18 of the 27 sam-pilng datos followed by the green and blue-green algal groups with 5 and 4 dates respectively. Greens and blue-greens were dominant only during the warmer months (Figures 6 and 7). A numerical dominance ranking of the plankton algse encountered by sam-pling station and date appears in Table 35 . The most abundant and frequently encountered diatoms were Melostra granulata, M. varians, pyclatella spp. and various unidentified pennate diatoms. Dominant green algae included Scenedes-mus quadrienuda, Ankistrodesmus convolutus, and Cosmarium spp. Blue-green dominant phytoplankters were Raphidiopsis curvata. Oscillatoria angustisrtmn.
~ - Anabaena sp. and Lyngbra op., Seasonal sh1fts in dominance were observed but there appear to be no biologically significant differences between stations on any given sampling date.
Results of this study have failed to demonstrato any measurable qualitative or quanttative effects of the operation of the Farley Nuclear Plant on puytoplank-ton communities in the Mjacent Chattahoochee River. lI lI !I 'I l l

Zooninnkton I Zooplankton densities varied seasonally as illustrated in Figure 35. With the exception of the January 1978 sample, zooplankton standing crops were lowest in winter months and highest in spring and fall months. High rotifer den-I sity in the January 1978 sample was unusual for this time of year and was appa-rently attributable to lov.Jr than normal water flows and low turbidity (Table ll). Based on results of plankton studies conducted in comparable streams in Ala-I bama and c?her adjoining states, zooplankton standing crops in this reach of the Chattahoochee River were considerably higher than would be expected. The great abundance of the cladoceran, Bosmina longirostris, in April 1977 and Maf 1978 is very unusual under rtwrine conditions. This is apparently due to the influence of the two upstream impoundments (Walter F. George Lake and Colum-bla Lock and Dam) on the study area. The abundance and vertical distribution of zooplankters in the water column at each station on each sampling date are illustrated in Figures 36 through 49. Patterns of distribution varied considerably between sampling dates but varia-tions betwen stations on any given date were minimal. Dominant zooplankters encountered during the course of this study are pre-sented in Table 36. The most abundant and frequently occurring organisms were: Kerstel'.'. cochlearts, Triebocerca spp. , Brachionus spp. Polvartbra spp. , Boamina longirostris, Cvelops spp. , Bosminopsis detterst, Ceriodaphnia spp. and Pseudosida bidentata.

I I' bestenfensis in cooler weather and the cladoceran Bosminopsis detterst in wwmer I weather was notable. Diversity (3) and equitability (e) indices were calculated for zooplankton communities at each station on each sampling date (Table 37 ) (Weber 1973). A hypothetical community consisting of 100 organisms evenly divided among 10 tan would have a 3 = 3.32 and an e = 1.43, wherets a community of 100 organisms with 90 in one taxon and 10 in the other wmld have a a = 0.47 and an e - 0. 7s. Variktion in Il and e was pronounced between sampling dates but these shifts were apparently due to seasonal changes in environmental conditions. On any given date organism density, number of taxa. 3 and e values were strikingly similar at all stations. Based on the results of this study there appears to be no evidence that the operation of the Farley Nuclear Plant beginning in June 1977 bas had detectable adverse effects on zoopinnkton communities in the adjacent Chattahoochee River.

I I Larval Fish Fishes in the Chattahoochee River near Farley Nuclear Plant can be cit.ssified generally as warm-water species, which will spawn anywhere g the habitat is suitable. Studies to determine the densities and types of , l larvae in the vicinity of the plant were conducted annually from 1975 through 1978. Samples were collected every two weeks. during the period March through June, with the exception of 1975 when studies were started in April because of flood conditions. Larval fish collected during the four-year study were obtained from four sample areas in the vicinity of Farley Nuclear Plant. Sample stations included: (1) an upstream station located approximately 0.9 miles above the plant intake, (2) an intake canal sample station, (3) a discharge
~
sample station, and (4) a downstream station located approximately 2 miles below the plant discharge. Larval fish were collect 1d from the intake canal station only during 19~B, which was the first sample season following comercial operation of Farley Unit 1. Ssmies were collected at depths of g 1.5, 3.0 and 4.6 meters. Sampling at the 4.6 meter depth was infrequent due to insuffici ntt water depth. Each sample was obtained by towing a plankton not with attached flowmeter and represented larvae obtained from approximately 100 cubic meters of watcr. Larval fish densities were computed for each sample area and sample peri d during the four-year study. Tables 38 througn 41 provide the results of larval fish monitoring during each of the study years.

1 f Tables 38 through 41 show that the Clupeidae (herring family), which includes the shad, represented the dominant taxonomic group in all sample areas throughout the study. The lesser groups represented during the study were the Cyprinidae, Catostomidae, Percidae, Ictaluridae, Percichthyidae and Pomoxis. A total of 662 larvae were collected during the four year study. The number and percent of the total representej by each of the previously mentioned groups is as follows; Clupeidae 619/93.5%, Catostomidae 11/1.7% Cyprinidae 6/0.9%, Percidae 4/0.6%, Ictaluridac 1/0,2%, Percichthyidae 1/0.2%, Pomoxis,1/0.2%, and unidentified 19/2.9%. Any attempt to describe the distribution of larvae in each of the three sample areas based on taxonomic differences would be less than conjactural based on the
; numbers previously described. The low densities of non-Clupeids is most probably due to lack of suitable spawning habitat in the vicinity of the plant.
The extremely unstable sand and gravel bottom of the Chattahoochee River in the vicinity of the plant and the 0.6 to 0.9 meter per second velocities resulting from a narrow river channel and operation of Andrews Dam (approximately 0.5 miles above the upstream sample station) make that portion of the river under study poor spawning habitat especially for these species which build nest or require semi-lentic spawning conditions.
)
The average number of larvae collected from each sample area, during each sample psriod, is presented in Table 42. Data presented in the previously referenced table indicates peak spawning (at least for the Cyprinidae) occurs during the months of May and June. Temperature and dissolved oxygen data collected during each of the larval fish sample periods are presented in Tables 43 through 46.

E Conclusions Larval fish studies conducted in the Chattahoochee River near Farley Nuclear Plant, during the period 1975 through 1978, indicated poor spawning success for fishes other than the Cyprinidae or Shad. Unstable bottom conditions resulting from high river velocities and associated operation of Andrews Lock and Dam are expected to be the primary contributing factors for low larval densities. Data collected during the study did not indicate that any differences among the three areas could be contributed to plant operation, but were closely tied to variations in natural environmental conditions in that portion of the river under study.

I Adult Fish Studies The collaction of fishery data on the Chattahoochee River near the Farley Nuclear Plant was begun in April 1975 and terminated in Novembe r,1978. Fish were collected from both the east and west banks of the river at three sample stations. Sample stations included. (1) an upstream sample area located approximately 1.2 miles above the plant discharge (2) a discharge sample area, and (3) a downstream sample area located approximately 2.0 miles below the plant discharge. Fish were collected from each of the previously mentioned areas on a quarterly basis, with the exception of the first quarter of 1975, during the four-year study. Electrofishing studies conducted in the vicinity of Farley Nuclear Plant resulted in the identification of 35 species. Table 47 contains a list of the connen and scientific names of the fish collected, es well as the sample areas in which they occurred. Fishery data obtained from electrofishing studies were used to detennine relative abundance and relative conditions (Kn) values for each species collected. The relative abundance of fishes collected during the study is based on the nuter of captures per minute of electrofishing. Catch per minute (or relative abundance) values were computed for each species collected during each of the 15 sample periods. Catch per minute values are presented in Tables 48 through 51. Catch per minute values computed for each species collected during the four-year study fluctuated considerably from season to season and year to year. Total catch per minute values were also computed for each of the sample areas for each sample period and averaged for each sample year. Total catch values and average yearly values for each sample srea are presented in Table 52. Average yearly catch values for each sample year indicate higher densities occurred in the discharge sample area during all yecrs, with the exception of 1977. A comparison of

I catch per minute values using the " student's t" test indicated significantly higher (95% C.L.) catch per minute values were obtained in the discharge area when compared to the downstream sample area using quarterly values from all sample periods. Catch per minute values were also found to be significantly higher (80% C.L.) in the discharge aret when compared to values computed for the downstream san;,le area. Total catch per minute values computed for each sample area during each sample period are prasented graphically in Figure 50. The relative condition (Kn) of selected fish species was computed for each fish collected and averaged for each species by sample periods. Relative condition values were computed by dividing the weight of a particular fish by a computed weight for a fish of that species and length. The length-weight data used for computing Kn values were obtained from a fifteen-year study conducted by the Department of Fisheries and Allied I Ac,uacultures, Auburn UniversityI . Condition values were computed for each fish for which data was available, and averaged for each species during the fifteen samp?? periods. l Average relative condition values computed for each species are presented by sample year and period in Tables 53 through 56. Relative condttion values for each species varied considerably fmm sample period to sample period, both witnin and among sample areas. The average conditior value for all species within each sample area was r.omputed and is presented by sample period and year in Table 57. The average condition values for all species which appear in the previously referenced table were compared statistically to determine if any differences existed between sample areas within sample years .

) following differences at a 95% C.L.: (1) condition values of fish in the discharge area were significantly greater than values computed for fish in l the downstream area during the 1975 sample year, and (2) condition ,41ues of fish in the downstream sample area were greater than values computed for fish in the upstream area during the 1976 sample year. A statistical
' comparison of fish conditions using quarterly averages for all sample years showed no significant differences existed among the three sample areas, even at a confidence limit of 60%. Graphical presentations of quarterly and yearly condition values, averaged for all species in each of the three sample a*reas, are shown in Figures 51 and 52.
I Conclusions Fish population values computed for each of the three sample areas-in the vicinity of Farley Nuclear Plant fluctuated considerably from season to season and year to year. Catch per minute values computed for each of the sample areas indicated the presence of higher fish densities in the discharge area, as compared to the upstream and downstntam areas. Di f ference in condition values computed for fish in each of the three areas indicated significant differences existed among sample areas during only two sample periods during the four-year study. It is concluded, based on the data collected, that variations in fishery population parameters do not indicate any significant changes in fish populations among the three sample areas during the study, but represent normal population fluctuations and habitat differences.

I I t Impingement Studies Impingement monitoring at Farley Nuclear Plant began on L December 1,1977 anc' extended through November 28, 1978. Fish and other equatic organisms impinged on intake screens were collected for one continuous 24-hour period every two weeks during the study. Organisms impinged during the 24-hour sample periods were obtained by passing the effluent from the screen wash system through a collection basket. Fish collected d ring the study were identified and individually counted. l wieghed and measured. The weights of fish were obtained as previously no!.ed, with the exception of small shad (Dorosoma sp.). Small shad were weighed in aggregate in order to increase the accuracy of weight determinations for this species. Impingement data were collected on 27 sample periods during the 12-month study. Impingement dcta collected during the study are presented in Table 58, which includes the number and weight of each species collected during each of the 24-hour sample periods. Impingement monitoring at Farley Nuclear Plant resulted in the collection of 2,537 aquatic organisms (see totals Table 58). The clam Corbicula Fluminea and the shad (both gizzard and threadfin) were the most numerous of the organisms collected. The Corbicula ,I and shad accounted for 88.27% and 7.96%, respectively, of the total organisms collected during the study. Thus, these two groups represented 96.33% of all organisms collected during the 12-month study. Aquatic organisms collected during the impingement study were divided into three general categories, which included game species, comercial species and other species. Organisms collected during impingement studies, and ci .sified as previously described, are presented in Table 59. I

I I The previously referenced table includes the total number and weight of each species collected, as well as the estimated daily and annual impingement rates for species identified. Data presented in Table 59 shows that l estimateo annual impingement rates for game, commercial, and other species were determined to be 268, 929 and 33,779, respectively. The estimated annual impingement rate of 33,779 organisms, as shown for the classification of other species, includes an impingement estimate of 30,891 for Corbicula. I Thus, the estimated annual impingement rate for all species of fish is 4.016. The estimated annual weight of fish impinged on intake screens was g determined to be 5.69 pounds (2.58 Kg) for gama species, 57.69 pounds (26.22 Kg) for comercial species, and 220.16 pounds (99.86 Kg) for other species. The estimated annual weight for all orghnisms impinged on intake . screens was detemined to be 283.55 pourds (128,62 Kg). The distribution of fishes and shellfish over the 27 sample periods I is presented in Figure 23. Most of the fish collected during the impingement study occurred during the late winter and spring. The impingement of fish during the previously mentioned period has been seen at other power plants throughout the State and is thought to be related to increased movement of fishes associated with feeding and spawning behavior. Variations in impingement rates for corbicula (see Figure 53) were very pronounced over the 12-mcnth study and are without explanation. The withdrawal of water through the intake system at Farley Nuclear Plant is characterized in Figure 54. Data presented in the previously referenced table indicates the minimum and maximum rates of water withdrawal which could have occurred during each of the impingement sample periods. Average flow rates for each 24-hour period could not be obtained since available infonnation on pump operation indicated the number of pump; running in continuous mode and the number of pumps set in the automatic mode. Thus, 1

m r-i data in Figure 54 shows flows known to occur (minimum flows) and flows which could have occurred (naximum i ows), based on the number of pumps on automatic. Data presented in Figure 54 is also shown in Table 60, which also includes sample dates and periods. The rate of water withdrawal, as previously shown, did not appear to be related to impingement rates for fish. Periods with high flow rates typically had lower fish impingement rates. The impingement of Corbicula, especially during the latter part of the study, did coincide with periods of high flow rates. However, the peak impingement period for Corbicula occurred during the second sample period when flows were low. The results of impingement studies at the'Farley Nuclear Plant indicate that the removal of fish and other aquatic organisms from the Chattahoochee River is sufficiently low that no significant harm to the I aquatic communities is expected to occur. Impingement rates for game species 4 were deteminsd to be extremely low. Estimated daily impingement rates for 5 game species of 0.73 is less than 2% of the daily creel limit per fisheman l for sunfish, as set by the Alabama Department of Conservation and Natural Resources. The impingement rate for commercial species was also considered to be low, with an estimated daily rate of 2.54 Tish. Impingement rates for shad and Corbicula, which represented the majority of organisms collected, were lower than would be expected based on the abundance of these organisms in the vicinity of the plant.
