1 1.0 IN'rRC'.qIm This is the second annual postoperational report on the ecology of the York Haven Pond of the Susquehanna River in the vicinity of Three Mile Island Nuclear Station (TMI!:5). The study by Ichthyolo'gical Associates, Inc. was initiated in February 1974 Most data from 1974 were reported in Potter and Associates (1975). Data from 1974 not coc:pleted for the first annual report and data from January through a December 1975 are herein reported. Sections are presented to cieet the Environmental Technical Specifications (ETS) for TMI:;S, Unit 1, Appendix 3. Para =eters analyzed are the same as reported in Potter and Associates (1975) with the addition of surveillance for bird impaction on the natural draft cooling towers, and possible effects of salt drift on terrestrial plants near the station.

SUMMARY
1.1.1 Impinge-mnt of Fishes Twenty-three 24-hr surveys were done January through December 1975 at the IMLNS Unit 1 Intake. A total of 476 fish of 26 species weighing 2.37 kg (5.22 lb) was impinged. Most of the fish were dead. The mean number of specimens per 24-hr survey was 20.7; mean weight was 103.0 g. An esetmared 5,556 fish weighing 37.6 kg (82.7 lb) were impinged during 1975. More fish were impinged during 1974 (1222 specimens; 21 surveys) than in 1975 (476;23). Total biomass was higher in 1975. 1.1.2 Entrainment of Ichthyoplankton Entrainment surveys were done semi-monthly April through October 1975. Totals of 67 larval fish, 6 juvenile fish, and zero fish eggs were collected. Percids were most cocoon. Larvae were taken sporadically and in nu=bers too low to calculate station incurred mortality. Ichthyoplankton entrainment surveys are suonarized for 1974 and 1975. 1.1.3 Entrainment of Plankton 1.1.3.1 Phytoplankton Phytoplankton results fram August through October 1974 rnd April through October 1975 are presented. Phytoplankton composition was similar in samples taken simultaneously at the Intake and Discharge on each date. Eighty-nine genera of six divisions were identified in 1974 and 1975. l0

1.1.3.2 Zooplankten Zooplankton results from 26-27 Septe=ber through October 1974 and April through October 1975 are presented. 4 A total of 85 taxa of zooplaniten and other invertebrates was identified in 1974 Small diel differences in cocposition and nu=bers of major zooplankto,n taxa vere noted during late Septe=ser through October. The composition and numbers of zooplankton at both the Intake and Discharge were similar on each date. Rotifers were est abundant. , Cladocerans and copepods were taken in lower tnzsers. Nrtality estimates range from 3.2 to 8.87,. Results from 1974 are su:znarized herein. A total of 85 taxa of zooplankton and other invertebrates was identified in 1975. Small diel differences in composition and nu=bers of zooplankton were noted. The cocposition and density of the major zooplankton taxa at both the Intake and Discharge were similar on each date. Cladocerans, recifers, and copepods were the ::est abundant zooplankton taxa accounting for 42.0, 31.5, and 25.47., respectively, of the zooplankton. Mean values of percentage zooplankton nortality range from 0.6 to 9.67.. The percentages of zooplankton entrained by TMIh"i and lost to the closed cycle cooling system as condenser nake up and to other factors are estimated. 1.1.4 Fish Fishes were sampled by seine and trapnet fra March through October 1975. 1560 021 O

4 t A total of 138 trapnet collections yielded 1,610 spescimens ot 22 , species; the channel catfisn was most numerous. All species except the tesse11ated darter were taken in greater nu=bers downstream from the Discharge. , A total of 75 seine collections yielded 6,574 specimens of 30 species; most fishes were taken in greater nu=becs downstream from the - Discharge. The spotfin shiner cocprised 44.3 of the seine catch. Monthly seine and trapnet station diversity indices varied greatly and were affected most by the presence of young and juvenile fishes.
. Most fishes taken by trapnet were juvenile or adult while wst taken ly - seine were young or juvenile.
No appreciable differences were noted in condition factor values for fishes downstream and upstream from the Discharge when sufficient numbers of specimens were present. The fish leech, Illinobdella moorei, was a cocoon ectoparasite. 1.1.5 Macroinvertebrates Macroinvertebrate collections were taken semi-monthly April through October 1975. A catal of 90,213 specimens representing 72 taxa was taken. Limnodritus hoffmeisteri, Chironomus sp. and L. udekemianus were the most abundant taxa taken. Lienodritus hof feelsteri was usually cost abundant at all stations each month. Manchly estimates of diversity ranged from 0.57 to 3.43. Index of percent similaritf values between stations were in the intermediate to high affl.-ity range () 507. similarity). 1560 022
5 A comparison with 1974 data indicated an increase in total numbers of specimens and taxa in 1975. 1.1.6 Arbient Water hality d oou CUub u j\j fh 1.1.6.1 Physicochemical Parameters - Except for dissolved oxygen and total suspended' solids the monthly distribution of parameters was similar. hean values were generally higher in July through September. The monthly mean concentrations of some parameters at 11A1 (TMINS Discharge) were higher than at other stations; some were si:silar. 1.1.6.2 Pecal Coliform The highest overall mean density of fecal coliform was at LA1. For all stations the gecretric mean af fecal coliform densities exceeded the limit established for the Connonwealth of Pennsylvania. 1.1.7 Therma! Pluine Mapping Twenty-eight plume maps were done during various river flow com *- tions and station operation levels. The effluent temperatures were within the ranges established in the ETS. A return of ef fluent tempera-tures to within 2.7 C of ambient was used to define the plume. In 20 of 28 cases the plume was limited tu the point of discharge. 1.1.8 Bird Impaction on Cooling Towers Two bird mortalities due to impaction were observed. Tvracy dead birds were found at the trash racks serving the two operating cooling towers. 1560 023
6 1.1.9 Effects of Cooling Tower Salt Drift on Agricultural Crops and Natural Vegetation i 1.1.t'.1 Plant Pathology Transects , Examination of plant pathology transects was conducted April through October 1975. No dif ferences were noted in flowering time or a,,pearance of the 216 taxa pbser"ed with respect to the location of possible salt drift. Plant parasitic diseases were found on two agricultural crops and 24 taxa of. natural vegetation, and insect damage was noted on 13 taxa. , None of the damage caused significant defoliation and no pattern was observed relative to IMINS. 1.1.9.2 Quantitative Vegetation Studies Two forests and four tields were surveyed August through October 1975; results w re statistically compared with those obtained in 1973 and 1974. There were relatively few charges in the overstory and understory in the forests. Some of the statistically significant changes in ground cover in forests and fields were related to natural or hu=an disturbance; others were normal in the course of secondary succession. Increases in non-vegetative cover were partly due to sampling differences. No pattern of change was found that was attributed to the operation of the cooling towers at TMINS. 1560 024

-< m 2.0 I'iPIEEE?.T OF FTSH The ETS, Appendix B, Seccian 4.1.1A required semi-conthly 24-hr impingement surveys at the TH1:3 Unit 1 Intake.
The Unit 1 Intake is ecciosed in a concre c building along*the west shore of Three : tile Island and is flush with the shoreline. River vater passes under a skinner vall, which has trash bars with two feet vertical spacing, through auto =ated trash racks, with one inch vertica'. s bar spacings, and through vertical trav;1ing scresns of 3/8 inch mesh before going through the river water pu=pr. The flow velocity under normal and low river flows and normal operating conditior.a is 0.2 f t/sec (A.E.C. 1972). Chlorine is normally added at the Intake at 0100, 0900, and 1700 hr every day. The fish and refuse from the autoctated trash racks and vertical travelin7, screens are washed into separate vira cesh bins. The bin for the traveling screen also receives the discharge from all river water pump autocarte discharge strainers of 1/8 inch cesh. 2.1 MZTHODS Methods were similar to those described in Potter and Associates (1975). Hararka and Sharca (1975) designed a sampling program to esti= ate the magnitude of fish ic:pingement at a given level of confidence (P) within a specific margin of error (d). They suggested that a P value of 0.15 or 0.20 be used with a corresponding d of 257. or less to determine the nu=ner of sacrples necessary to estimate the magnitude of 1560 025 O
8 fish impingec-nt, the number of sa.:ples necessary to describe the impingen,ent fish populacion at TMISS was calculated af ter Elliott (1971): N = (t2 )(s2)/(d 2)(52) where t = t-value obtained from a t-table atsn-1 degrees of freedom for significance levels of 0.15 and 0.20. s2 = the sample variance d = the margin of error of 0.20 and 0.25 Y = the mean number per 24-hr survey N = the number of samples needed. n = the nu=be'r of samples taken. Estimates of total number and biomass impinged at THINS during 1975 were made using clie following formula: . T = (5)(365) where T = estimate of number or biomass Y = mean number or biomass per 24-hr survey. Estimates for 1974 were made and impingement results from 1974 (Potter and Associates 1975) and 1975 were compared. 2.2 RESULTS hrenty-three impingement surveys were performed, two each month except October when mechanical problems at the trash bins prevented sampling. Alive and dead totals for fishes taken during each time period and stae-maries of each 24-hr survey are presented in Tables 2.2-1 through 2.2-46. A total of 476 fish of 26 species weighing 2.37 kg (5.22 lb) was impinged (Table 2.2-47). Most of the fish (355 spen, 74.67.) were ,: ecd and were either young or juvenile. The four most common species accounted for 67,57. of the specimens; they were the tesse11ated darter (36.17.), channel catfish (15.87.), spot-tail shiner (9.57.), and spotfin shiner (6.17.) Table 2.2-47. Each of the remaining species represented less than 5.07. of the numbers. 1560 026
9 D** *D C ( wo vJ ,. > The nuser of fish i= pinged per 24-hr period ranged fro:n 0 to 75 (Table 2.2-47). The cuan number impinged per survey (X) was 20.7; the variance was 316.8. The coefficient of variation defined as C = 100 s/5 was 86.07. (s = standard deviation). ' The mean biocass per survey was 103.0 g; the variance was 26,082.25. The coefficient of variation was 156.S';. Mean weight per fish was 5.0 g. . The estir.ates of nu=bers of sac:ples needed to describe the impingement fish nopulation are presented in Table 2.2-48. At acceptance level8 d = 0.25 - and level, of significance P = 0.20 the number of samples taken during 1975 was adequate to describe the impinge:rtat fish population. The 1975 yearly estimate of number of fish imping,.d was 7,556; the estimate of biocass was 37.6 kg (82.7 lb). 2.3 M?cttSION lo?t. AND 1975 liste fish were i= pinged during 1974 (1,222 specimens; 21 surveys) than in 1975 (476; 23). Total biomass was higher during 1975 (2.4 kg) than in 1974 (1.9 kg) as a result of impingement of a few large specimens (eg. a carp,120.9 g on 23 January; and a quillback,145.0 g, smallmouth bass, 224.7 g, and black crappie,120.8 g all on 20-21 March). The same fishes were coc=en each year; the cesse11ated darter was uost abundant both years; channel catfish, spottail shiner, and spotfin shider were also cocnon. Estimates for nu=bers of collectices necessary to describe the 1974 impingement fish populations were calculated (Table 2.2-49). Because of the greater variance (4945.4) during 1974, core collections would h;ve been necessary to adequately describe the impinged fish populations. Based on the expansion of 1974 data it was estimated that 21,243 fish and 1560 027
b 33.5 kg (73.7 lb) of fish were impinged. This contrasted to fever fish (7,556) and greater bio = ass (37.6 kg) impinged during 1975. Many of the specimens reported impinged during both years were small especially in regards to the 3/8 inch mesh of the vertical traveling screens. Exper4-wen 1 sa=ph with a D-f.rame net at the discharge of the river water pu=p succentic strainers suggested that some of the fish thought impinged on the scree.as actually could be froci the pu=p strainers. Numbers and biomass i: pinged at TMINS vere low during approxicately two years of sampling. A cursory examination of fish vgight data presented in Section 5.0 shows that the biocass of fishes impinged in either 1974 or 1975 was small relative to the bio = ass'of fishes captured by trapnet upstream and dovustream of the Discharge. The impact of impingecent on the river ecosystem is therefore probably small. The Environmental Technical Specifications required sampling for two years. Sampling vill therefore be continued until the end of February 1976 as described in the ETS. A.E.C. 1972. Final envire=cental statement related to operation of Three Mile Island Nuclear Station.

~
Intake and Discharge at 4-hr intervals during the 24-hr surveys to deter-mine the nu=bers and composition of larval fish and to determine station . incurred mortality, a 3.1 METHODS Ichthyoplankton samples were taken using a Lindsay4torrisson plank-ton pump as described in Potter and Associates (1975) with the following modifications (Figure 3.1-1). The original collection chamber (14cm (5.5 inch) inside diameter, 96 cm (37.8 inch) height j was replaced with a modified pressure feed tank [35 cm (13.8 inch) inside diameter, 51 cm (20.1 inch) height) to decrease mortality due to impaction and turbulence within the cha=ber. The net (No.10 mesh; 0.158 cm) was fastened with a collar directly to the chamber intake. The videned part of the net was supported with a rattan ring seated on an iron flange velded to the inside of the chamber thereby suspendieg the collection cup above the chamber bottm. Samples were taken from the intake bays through a pipe which ran under the skicner vall. The pipe was pu= ped out prior to each 24-hr study to avoid contamination of samples. The above technique differed from that of 1974 in that it provided a standardized collection location i and ensured san:pling of entrained water. t i 1560 058 :
41 The Discaarge was sampled by attaching the cylinder intake hose to a cable at the mouth of the discharge pipe, to assure standardization of location of sa=pling. Collection of sa=ples and physicochemical data was done from a boat at each Iccation. 3 Two 400 gal (1.5 m ) ichthyoplankton saq.les were taken at each 4-hr interval; two samples were taken to les=:n the effect of collection on the larvae and still allow for a large sample volu::n. For tabulation and discussion the two samples were combined. The sa=ples were taken to a mobile laboratory located near the collection sites where they were e sorted as to live (larvae showin;; movement, transparent body) or dead (no movement, opaque to white color) conditi.on and preserved for later identification. Larvae were identified to the lowest feasible taxa using a stereoscopic dissecting scope, and measured to the nearest 0.1 tra with an ocular micrometer or a Helios precision hand caliper. Identifi-cations were aided by the following materiais: Fish (1932), Lippson and Moran (1974), Mansueti (19 %), Mansueti and Hardy (1967), Meyer (1970), Norden (1961), Snyder and Snyder (1975), and personal coc=unications, notes and refe.ence specimens provided by ether Ichthyological Associates. Inc. personnel. D**D *D'3' h 3.2 RESULTS oo ob - t m Results of each 24-hr study are given in Tables 3.2-1 t'arough 3.2-14 All fish discussed are larvae unless otherwise noted. Totals of 67 larvae and 6 juvenile fish were collected during 27 May through August; none were taken in April, on 12-13 May, in September, and October. No eggs were collected. 1560 059

Twenty-five larval fish including 8 cyprinids,13 catostomids, and 4 percids were collected in the 27-28 May survey (Table 3.2-4). Most were taken at night. The 16-17 June survey yielded three percids (Table 3.2-5). Two a cyprinids, 3 centrarchids, and 27 percids were taken on 23-24 June (Table 3.2-6). During the first July survey two juvenile Ieea1urus punctatus (channel e catfish) were taken (Table 3.2-7). The second July survey yielded six larval and three juvenile fish of four families (Table 3.2-8) The first August survey yielded one juvenile Notropis spilopterus (spotfin shiner) (Table 3.2-9). The second August survey yielded one larval Lepomis ribbosus (pumpkinseed) (Table 3.2-10). 3 Numbers and densities (n/m ) of fish collected are given in Table 3.2-15. The highest density recorded was 4.67/m3 at 0400 he on 24 June. Densities were higher at night and at the Intake than at the Discharge. Percids (perches) were most common with 35 specimen (47.97.) (Table 3.2-16). Yellow perch were identified; specimens of Etheostoma, spp. were probably E. olmstedt (tessellated darter) or E. zonale (banded darter). Cyprinids (minnovs) and catostemids (suckers) were equally represented (13 specimens,17.87.). Minnovs included cyprinus carpio (carp), Notropis hudsonius (spottail shiner), and spotfin shiner. caroiodes everinus (quillback) was the only sucker. - Centrarchids (sunfishes) =ade up 11.07. of the catch with eight speci-mens; I.epomis gibbosus (pumpkinseed) and L. macrochirus (bluegill) were represented. Larvae were taken sporadically and in too low nu=bers to calculate station incurred mortality. 1560 060
43 D**o P lo vyf 3.3 SU?^fARY 1974 1975 oo o AL AIUL Nus:bers and densities of larval fish collected during 1975 entraircent studies were lower than those taken in 1974 (Potter and Associates,1975). Createst densities were collected at night during both years. Percids were most co::::en (487. of the catch'in 1975, 697. in 1974). Entrairment studies during 1974 and 1975 indicated low densities of larval fish at the l' nit 1 Intake. This may be due to the depth of saj::pling, , usually greater than five feet, near the bottom of the skicz:er vall. The vall, designed to prevent the entrance of floating material, could reduce
'the entrainment of larval fish which tend to stay near the water surface.
The extremely low densities of larval fish at the Discharge c:ay be due to the operation of the river vster pu p discharge strainers. Estimates of station incurred mortality were not possible either year due to lov numbers of specimens collected. It is reasonable to expect near 1007. mortality due to the station because of 1/8 inch mesh strainers at the discharges of all river water pu=ps. The Enviroreental Technical Specifications required ichthyoplankton entrainment studies for two years. The requirements for sa=pling and report-ing were fulfilled as of this writing and the program has been terminated. Fish, Maria Poland. 1932.

53 4.0 EhTIAIhMEST OF PLANKTOM The ETS Appendix B, Section 4.1.lC required semi-monthly 24-hr sampling for plankton from April through October. Samples were taken at 4-hr intervalt ac both the THINS Intake and Discharge. 4.1 s THYTODUNKTON 4.1.1 METHODS AUGUST T M UCH OCTOBER 1974 Phytop,lankton samples were taken at the surface from in front of the trash rake unit in the Unit 1 Intake and from the Flow and Radiation Monitor Pit near the Discharge. One liter samples were collected at 4-hr intervals with a bucket. All sr ples were preserved and stained with 107. Lugol's solucion. Samples were concentrated after three weeks settling time to between 0.1 and 0.21 volumes by siphoning off the supernatant. Phytoplankton enumerations were made with a Palmer-Maloney cell at 200X cagnification. Subsa=ple size was 0.1 ml and the volume searched .ias 0.005 m1 to 0.1 al depending upon the phytriplankton density. Taxa were identified to genus or species at 400X or 1000X magnification. Counts were made in ter=s of
" units" a method codified by Ichthyological Associates (1972) from Tucker (1948).
With the exception of the Bacillariophyta (each cell in a chain was counted), one cell, colony, or 10 cell fila =ent was equivalent to one
" unit" (Table 4.1-1). Many phyto-flagellates were unidentifiable in the preserved sa=ples; these taxa were lumped and listed separately in the tables.

Intake and Discharge were co= pared usi=g the formula (Simpson et al.1960): t = d/YsUn where: d = cean difference between densities of a plankton division s2 = variance n = nu=ber of paired observations. 4.1.2 RESf7LTS AUGUST 1HROUCH OC Om 1974
- A total of 152 phytoplankton sa=ples was collected during thirteen 24-hr entrainment studies in 1974. analysis was con:pleted on 82 sa=ples taken on 25-26 April, 9-10 and 23-24 May, 6-7 and 20-21 June,11-12 and 25-26 July and vas reported in Potter and Associates (1975). The data and analysis for the re=aining 70 sa=ples collected on 15-16 and 29-30 August.
12-13 and 26-27 Septe=ber, and 10-11 a:d 24-25 October are herein reported. Two samples were not taken at 1600 and C500 hr on 10-11 October due to lack of access to the intake sa=pling site. Eighty-nine genera belonging to six divisions of phytoplankton were identified in 1974 (Table 4.1-2). The chlorophyta (green algae) were represented by 43 genera and the Bacillarfophyta (diatoms) by 26 genera. Nine genera of the Cyanophyta (blue green algae), 4 genera of Pyrrophyta (dinoflagellates), and three genera each of the Euglenophyta (euglenoids) and Chrysophyta (yellow-green algae) were identified. Common genera such as Pediastrum and Scenedesrus were represented by more than one species. Data on phytoplankton abundance and ca position in samples taken during each study are presented in Tables 4.1-3 through 4.1-8. Mean density and relative abundance of each phytoplankton division for each 2t-hr period are given in Table 4.1-9. Phytoplankton co= position was si-fin in sa=ples taken si=ultaneously O eOOb M S 1560 072
55 at the Intake and Discharge on each date. Although apparent differences were sometimes observed, phytoplankton density was not generally different at either site over an entire 24-hour period. Paired t-tests, calculated for each plankton division, indicated that apparent differences in abundance were not significant (P = 0.05), except on 15-16 August when slightly lower numbers and on 12-13 September, when slightly higher numbers of t'hlmeisyi.a were found in the Discharge. The co= position and relative abundance of the phytoplankton varied from month to conth. Only data from the Intake are discussed e-because of the above mentioned similarity of composition. Mean phytoplankton densities were higher in August than in Septe=ber and October (Table 4.1-10). Taxa belonging to the chlorophyts co= prised 477. to 487. and those belonging to the Bacillar!.ophyta 237. to 257. of the phytoplankton populations found on 15-16 and 29-30 August. Ankistrodesms fr.1catus, Colendinia radiata, Scenedesas c:uadricauda (all Chlorophyta), Cvelotella spp. and Tabe11 aria fecestrata (both Bacillartophyta) were the most abundant members of a diverse population. In Septe=ber, the Bacillariophyta and the Chlorophyts were equally dominant, each representing about 387. of the total population. Cyclotella spp. and Ankistrodesrus faleatJs were the most abundant taxa. The Bacillariophyta, especially Cvelotella_spp., Melostra spp. and Navicula spp accounted for 487 to 727. of the total population on 10-11 and 24-25 October. A nkistrodesms falcatus was the most abundant member of the chlorophyta (197. to 257.). h 1560 073
4.1.2.1 St"ARY 1974 Phytoplankton co= position and abundance were generally similar at the Intake and Discharge during all 24-hr studies (Table 4.1-10). The Bacillariophyta, particularly Cvelotella and Melostra, were cost i abundant in May, and were com:non throughout the year. Anterienella was e dominant in April, Navicula in April and October, Synedra from April to July and Tabe11 aria in August. Increasing numbers of Chlorophyta were found in the late spring and su=:ner; Ankistrodest:us, Scenedesnts, e Dietvowhaerius, Micractinitra, and Colenkinta were cost abundant. The Cyanophyta, especially Oscillatoria and Anaevstis were at their seasonal maximu:s in July; the phyto-flagellates peaked in August. 4.1.3 METHODS 1975 Methods were as state:: in Section 4.1.1 except that Discharge sa=ples were taken at the mouth of the discharge pipe at the river. 4.1.4 RrSUI.TS 1975 A total of 166 phytoplankton sa=ples was collected during fourteen 24-hr entrain =ent studies in 1975. Discharge san:ples were not taken at 1600 and at 2000 hr on 21 April 'te to a sa=pling mistake. Ninety-five genera belonging to six divisions of phytoplankton were identified in 1974 and 1975 (Table 4.1-11). The Chlorophyta were repre-sented by 49 genera and the Baci11ariophyta by 27 genera. Nine genera of Cyanophyta, 4 genera of Chrysophyta and 3 genera each of the Euglenophyta and Pyrrophyta were observed. Coc=on genera such as Pediasert=2 and Scenedescus were represented by more than one species. Data on phytoplankton abundance and co= position in sa=ples taken during each study are presented in Tables 4.1-12 to 4.1-25. Mean density 1560 074
57 and relative abundance of each phytoplankton division for each 24-hr period are given in Table 4.1-26. The species composition of the phytoplankton was similar in sa=ples taken at the Intake and Discharge during each 4-hr sampling period. Although apparent differences were soc:etimes observed, phytoplankton densities were not generally higher or lover at either site over an entire 24-hr period. Paired t-tests calculated for each plankton division . indicated that differences with few exceptions'in the abundance were not significant (P = 0.05). On 16 June the Chlorophyta were more abundant* and on 25 August the Cyanophyta vere slightly less abundant in the Discharge. The nu=ber of phyto-flagellates was significantly lover in the Discharge on 7-8 July. In the following discussion of seasonal distribution, only data from the Intake are used. In April and May taxa belonging to the Bacillario-phyta, particularly Cvelotella spp., Melostra spp., Svnedra spp., and Asterionella fo-coma, accounted for approximately 59% to 88*. of the total phytoplankton population (Table 4.1-26). The mean density of diatoes increased from 88,700 cells / liter on 7-8 April to 7,350,500 cells / liter on 27-28 May. In June the three most abundant phytoplankton divisions were the Bacillariophyta (27% to 52*. of the population), the chlorophyta (30% to 457.) and the cyanophyta (less than 5%). Prevalent species included Cyclotella spp., Svnedra spp., and Nitzschia spp. (all diatoms), and Mistrodes us falcatus, Actinastrum hantzscFM, Dicevosphaerium pulebellum, and Scenedestus spp. (all green algae). Phyto-flagellates were also cocx:en (157. to 23".). 1560 075
Bacillariopbyta were abundant (677. to 727. of the population) in July. Mean diatos densities were higher (13,114,999 cells / liter) on 7-8 July than at any ocher tima; Tabe11 aria fenestrata was dominant. Phyto-flagellates were emn (157, to 167.). In August and September the Chlorophyta, primarily Colendinea radiats, Scenedescus spp. and Ankistredeems falentus, represented 427. to 637. of the - population. The Baci11ariophyta, particularly cvelotella spp. and , Stephanodiscus spp., vere less n==erous (37. to 347.). Phyto-flagellates represented 177. to 22% of the population. ' Hean phytoplankton densities were lower in October than in August and Septe:ser. Diatoms such as Cvelotella spp. and Melostra spp. were the cost cornon taxa (617. to 647. of the population). Phyto-flagellates were also cocoon (237.). , As of this writing the EIS requirements for entrainment studies concetning phytoplankton are fulfilled. No further studies appear necessary, therefore analyses of phytoplankton entrainment in relation to TMI:s have been terminated. Ichthyological Associates. 1972.

94 4.2 200PIANKTON 4.2.1 METHODS SEMEMBC AND ocTO?ER 1974 Hethods were as described in Potter and Associates (1975). 4.2.2 RESUI,TS SEMEM3ER AND OCTOBER 1974 Analysis of sa=ples taken from 25-26 April through 12-13 Septe=ber 1974 was coc:pleted and reported in Potter and Associates (19U}. Analysis was cocpleted for samples taken on 26-27 Septeper,10-11 and 24-25 October; the results c.re herein reported. A total of 85 taxa of zooplankton'and other invertebrates was identified in 1974 (Taole 4.2-1). Data on the abundance and cocposition of zooplankton taken on each date are presented in Tables 4.2-2 through 4.2-7. Small diel differences in the composition and density of ciajor zooplankton taxa were noted (Tables 4.2-8 through 4.2-10). The ce= position and density of zooplankton at the Intake and DischarT.e were similar on each date (Tables 4.2-11 through 4.2-13). Seasonal fluctuations are described using data taken at the Intake. Rotifets were the most abundant taxon and accoup**' for 90.8 to 97.27. of the zooplankton. Brachionus cuadrmentatus and B,. calveiflorus were the most coc=nn species. Cladocerans and copepods were taken in low numbers and accounted for 1.2 to 4.87. of the zooplankton. Cyclopoid copepodids and nauplii (ic=:ature stages) were the most co:xaon copepods. No single cladoceran species was cocoon. 1560 112
Hortality estimates were made for all samples (Tables 4.2-14 through 4.2-16); mean values for each entrainment study were 8.87. (26-27 WMr), 3.27. (10-11 October), and 3.87. (24-25 October). 4.2.3
SUMMARY
1974 Zoachnkton compositiori and abundance were generally similar at the Intake and Discharge during each 24-hr study, April through October 1974. Diel differences were small. ~ Ratifers were the most abundant taxon during all entrainment studies except 15-16 August (Table 4.2-13). Brachionus cuadridentatus and 1. calve 1florus were the most comoit species. Cf =herans and copepods, cocoon throughout the year, were collected in greatest numbers in late July and Augt.)t. Bomins Innet rostris was the most ccaraon cladoceran collected. Cyclons vernalis, cyclopold copepodid, and nauplit were the most comon copepods. Estimates of zooplankton mortality were made for eight of thirteen 24-hr studies. Mean values for percentage zooplankton mortality ranged from -1.2 to 8.8'. with the grand mean for 1974 of 2.47.. 4.2.4 MET 1f0DS 1975 Replicate (2) samples were taken semi-monthly at 4-hr intervals for 24 hr, April through October. Additional sa=ples (3 to 4) were taken at 1200 hr at both the Intakes and Discharge from 7-8 April through 23-24 June. Samples were taken by pump (cuadiff. d from 1974) as described in Section 3.0 The pump was fitted with a No. 20 (0.08 m) mesh net. Sample size wrs either 0.38 m3 (100 gal) or 0.76 m3 (200 gal) dependent upon observed zooplankton densities. 1560 113

) l l b
A live count technique similar to that described in Potter and Associates (1975) was utilized for estimating percentsge zooplankton mortality due to entrainment. Sanples were concentrated icmediately after collection. Two 1 al subsamples were withdrawn using a Hensen-Steeple pipet. Each subsample was placed on a Sedgewick.-Raf ter counting
- cell and sorted for nu=bers of dead zooplankton; these were limited to abundant or prominent (size) rotifers (Brachio tus spp, and Euchlants sp.),
and all cladocerans and copepods. Mortality estimates were not possible
. during all entrainment studies because of low zooplankton densities or large amounts of suspended solids in the water.
The percentage of dead organisms per cubic meter was calculated from the ratio of the nu=ber of dead organisms per cubic e.eter and the total number of organisms per cubic meter; total nue:bers were determined from quantitative analysis of the samples. The mortality of zooplankton was derived by subtracting the percentage of dead organisms at the Intake (mortality due to sampling; all organisms were assucud alive when collected) from the percentage of dead organisms at the Discharge. The percentage influent used as condenser make-up (C) was calculated using the following forrula: C = { (I - E) + b - m] 100/I where: I = Influent (m3/ min) calculated using the number of pumps and their rated discharge (A.E.C.1971) E = Effluent (m3/ min) recorded by ntINS b = 7.6 m3 /min; estimated blowdown (A.E.C. 1971) m = 1.5 m3 / min; maximum evaporative loss at the cechanical draf t cooling tower (A.E.C. 1971) 1560 114
.~ v i
97 The percentage of entrained zooplankton lost (Z) was equated with the condensor make-up (C = Z) with the assumption that 100% of the zooplank-ton in the water used as condenser make-up was lost in the closed cycle cooling system. The total entrained zooplankton lost (N) was calculated using the formula: N = (I)(Dg ) - (E)(DE where: Dg = Zooplankton density at the Intake Dg = Zooplankton density at the Discharge For quantitative analysis, four one mi subsamples from each collection were analyzed (April through 3-4 Septe=ber). One mi subsamples were taken and analyzed until 200 organisms of one taxon were counted or up to a total of four one mi subsamples were withdrawn (22-23 September through October). For discussion densities were quantified as low (less than 1000/m3 ), 3 moderate (1,000 to 20,000/m ), and high (greater than 20,000/m3). 4.2.5 RESULTS 1975 A total of 85 taxa of zooplankton and other invertebrates was identified (Table 4.2-17). Data on the abundance and composition of zooplankton during each 24-hr study are presented in Tables 4.2-18 through 4.2-45. Small diel differences in the composition and density of major zooplankton taxa were noted (Tables 4.2-46 through 4.2-59). The composition and density of the major taxa at the Intake and Discharge were sLmilar on each date (Table 4.2-60). Because of these
,L
98 . I S similarities, seasonal variations were discussed in respect to only i Intake collections. Cladocerans, rocifers, and copepods were the most abundant zooplank-2 ton accounting for 42.0, 31.5, and 25.47., respectively, of the zooplankton. . Cladocerans were taken in low numbers in April through June; during July and early August e numbers increased, reaching a peak (134,807/m3) i on 11-12 August when cladocerans comprised 55.17. of the zooplankton 2 (Table 4.2-60). . Numbers were high through August and September; lov , I numbers were found in October. [ i Bomina foreirostris accounted for 88.87. of t he cladocerans. ; Numbers were low in April through early July; they increased to a peak , 3 (125,222/m ) on 11-12 August (Table 4.2-61). rachnia spp. and Diaphanosome spp. followed in abundance. Numbers of rotifers were low in April through 16-17 June; they increased to a peak (50,148/c3) on 25-26 August (Table 4.2-60). Numbers decreased in early September and increased to 98,048*E in late September. Rotifers accounted for 86.47 of the zooplankton on 22-23 September. Iow numbers were taken in October. nrachionus calveiflorus comprised 42.77. of the rocifers. Nu=bers . were low through 7-8 July (Table 4.2-61). Successively higher peaks . were observed on 21-22 July (2,955/c3), 25-26 August (24,143/m3 ), and 22-23 September (59,550/c3). Numbers were low between the peaks. None i was collected in October. 1. angularis (11.47.) was tsken in greatest numbers on 25-26 August, 1. budapestinensis (8.07.) and 1. caudatus ' (7.97.) were caost comon in September. Unidentified rocifers (6.37.) were taken in low to caoderate numbers throughout the year. 1560 116 :
~ -- T
_ _ _ ~,.. - m,. 99 Copepods were taken in low numbers in April through 7-8 July, moderate nu=bers in late July and peak nu=bers (97,835/cd) on 11-12 August (Table 4.2-60). Nu=bers declined in late August through October. Cyclopoid copepodids and nauplii (immature stages) were the most - abundant copepods and accounted for 49.6 and 37.07. of the copepods. Peak numbers of the iccature stages and Cvelops vernalis were taken ~ on 11-12 August (Table 4.2-61). Nematodes, tardigrades, oligochaetes, ostracods, and insects were collected in low numbers throughout the year. Ciliophorans were taken in low numbers at the Intake; they were more cocmon at the Discharge (Table 4.2-62). The percentages of zooplankton cortality varied during each 24-hr study (Tables 4.2-63 through 4.2-67); mean values were 3.67. (7-8 July), 2.67. (11-12 August), 0.6% (25-26 August), 0.7% (3-4 September), and 9.67. (22-23 September) with the grand mean of 3.47. for 1975. The percentages of rotifers and cladocerans entrained by TMINS and lost to the closed cycle cooling system as condenser make-up and to other factors were variable during periods of low zooplankton densities (Table 4.2-68). The percentage of rotifers lost was less than expected if 1007. is lost in the condenser make up. Percentages lost for cladocerans showed little or no correlation with the percentage of cladocerans in the condenser make-up. The percentages of copepods lost to the closed cycle cooling system were similar to the percentages of influent used as condenser =ake-up. 1560 117
100 During periods of higher zooplankton densities the percentage of cladocerans and copepods lost within TMINS was in all instances higher than the percentage of influent used as make up. Values for rocifers remained variable. 4.2.6 DIstmssION We examined only the effects of TMINS on entrained zooplankton populations. From this we could not determine the effect of entrain =ent loss )n the remaining river populations. If we assume random distri-bution of zooplankton in the river the amount of zooplankton lost from the river system amounts to less than one percent of the river zooplank-ton populations during most river flow conditions. Zooplankton densities and composition .ay be very different in any one section of river because of selective alimination and because the majority of zooplankton in the river comes from backwaters and ponds which adjoin the river (Hynes 1971). Thus, the loss of zooplankton may be gr ater than one percent of the river populations. The ETS requirements concerning entraic=ent of zooplankton were cocpleted as of this writing; studies therefore have been terminated. Anonytnus. 1971.
