1. INTRODUCTIUN This report presents the results of aquatic ecological studies conducted oy Ecological Analysts, Inc. (EA) during 1982 in the vicinity of tne Nine dile Point proinontory in soutneastern Lake Ontario. These aquatic studies were conducted in accordance with Environuental Technical Specifications for tne Nine Mile Point Unit 1 and the James A. FitzPatrick nuclear generating sto-tions, as prescribed by the United States Nuclear Regulatory Comuission.

The ecological interaction of the Nine Mile Point Unit 1 and James A.

FitzPatrick plants with the Lake Ontario environment in the vicinity of tne Nine Mile Point promontory has been under study since the 1960s. This 1982 study represents a continuation of those early studies which were initiated during construction of the two nuclear plants (Nine Mile Point Degan operation in December 1969, James A. FitzPatrick started operation in July 1975).

The two stations are located on the shore of Lake Ontario approximately 11 kilometers (seven miles) nortneast of the city of Oswego, New York. Nine Mile Point Unit 1 is a 620 MWe boiling water reactor with tne cooling water intake structure located off shore in approximately 7.6 meters (25 feet) of water and the discharge structure located near shore in approximately 5.2 meters (17 feet) of water. James A. FitzPatrick is an 821 MWe boiling water reactoe with the water intake structure located near shore in approximately 7.3 meters (24 feet) of water and the discharge, with a 236-meter (774-ft) diffuser, located off shore in approximately 9.1 meters (30 feet) of water.

This annual report consists of data descriptions and discussions of results fran the sampling progran conducted by EA fraa January 1982 througn Deceaber 1982. The sampling progran included impingeaent studies at both power plants throughout the year and gill net collections from thc vicinity of the tso nuclear generating stations from April through Decenber. Chapter 2 describes field fisheries, impingenent, and laboratory methodologies. Cnapter 3 treets the results of in-plant impingement studies and Lake Ontario Studies. Chapter 4 is a comparison of results froia gill net and impingeuent saupling. Chapter 5 l

provides an environmental impact assessuent as required by the Environmental Tecnnical Specifications.

2. METHODS AND MATERIALS i l

2.1 LAKE ONTARIO STUDIES  !

The sampling design and methods described in this section represent a continua-l tion of a program that has evolved as a result of cnanges which occurred during the spring of 1979 in U.S. Nuclear Regulatory Coanission Environmental Techni-cal Specifications for the Nine Mile Point Unit 1 and the daues A. FitzPatrick

[

nuclear power plants.

2.1.1 Gill Net Sampling Gill net sampling for the 1982 program was conducted along four transects extending perpendicular from the Lake Ontario snoreline (Figure 2-1). The transects HMPP (Nine dile Point Plant) and FIT 4 (Jeaes A. FitzPatrick Plant)

! represent a zone in the lake near the two plants submerded intake and discuarge structures. This zone can oe influenced by the removal of cooling water and by i subsequent thennal discharges and has been referred to as the experimental l area. The transect to the west of the power stations, f2iPW (Hine Mile Point West),is senerally upcurrent (approxiiaately 1.1 statute kilo.neters) of the experimental area with respect to the prevailing currents, and tnus represents a zone considered outside the influence of the intakes and toenaal discharges;

[ tnis area has been referred to as a control area. The f44PE (Nine Mile Point East) transect is usually downcurrent (approximately 1.9 statute kilometers) from the discharge structures with respect to tne prevailing carrents and represents an area that sometimes is influenced by the thennal discharges; this zone has been referred to as the far-field area.

Sampling of finfish with gill nets during 1982 was conducted twice a month fro.a April through August and montnly froia Septenber through December (Taole 2-1).

One experimental gill net was set at eacn of the four sampling stations. Eacn l gill net measured 2.4 meters (8-ft deep) and 45.7 meters (150-ft long), com-i prised of six 7.6-meter (25-ft) panels with bar-mesh , sizes ranging from 1.3 cm l to 6.4 cm in 1.3 cm (0.5 to 2.5 inches in 0.5-in.) increnents. All nets were set parallel to shore at the 9.1-meter (30-ft) depth contour. The nets were set at sunset of the night preceding an impingement collection and retrieved approximately 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> later.

2.1.2 Laboratory Processing After collection of the nets, the samples were returned to the laboratory and all organisias W re sorted, identified, and enumerated. Identification was made to the lowest possible taxonomic level, which was usually species. For the convenience of the reader co,amon names are used in tne text; nowever, a list of connon and their associated scientific names are included in Appendix E. For i each taxa collected, total number and total weight were detennined. In addi-l tion, individual lengths and individual weignts were recorded for a maximu.a of 40 speci,aens per species per gill net collection. Total lengtns were measured to tne nearest millimeter; weights were measured to tue nearest 0.1 gram for specimens less than 10 grams, to the nearest 1.0 gram for specimens between 10 and 2,000 grams, and to the nearest 25 grams for specimens over 2,000 grams based on the precision of the scales used for measurement. Any unusual cond-itions, abnormalities, or presence of fisn tags were noted on the data sheets.

2.1.3 Data Analysis Caten data from gill nets were expressed as a caten-per-unit-effort (c/f) wnere a unit of effort was defined as a 12-hour set:

12) c/f =

wnere X = number of fish caught in the sanple T = duration of set in nours.

2.2 IN-PLANT STUDIES 2.2.1 Impingeaent Sampling In accordance with the requireraents of the NRC's Environmental Tecnnical Speci-fications, innpingement catches were monitored on a frequency of 4 to 20 samples per month froin January through Decenber 1982 at the Nine Mile Point Unit 1 and the James A. FitzPatrick nuclear power stations (Table 2-2).

Samples were collected over a 24-hour period on randomly selected days.

Saaples were initiated around 1300 hours0.015 days <br />0.361 hours <br />0.00215 weeks <br />4.9465e-4 months <br /> of. tne sampling day and were ter-minated 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> later. Organisuis impinged on the traveling screens were mechanically washed into a collection basket with a 9.5 am (3/8-in.) stretch mesn net liner. The collection basket renained in place for the duration of the sample, unless high impingement or deoris loads required that it be emptied, in wnich case it was reaoved, enptied, and repositioned.

Plant operational data were obtained for eacn sampling date to document cooling water flow rates, intake and discnarge tenperatures, and power production.

Meteorulogical data sucn as wind speed and direction and air te.iperature were obtained twice during the iiapinseaent sample.

Plans existed for continuing impingenent monitoring at either power plant if impingement rates exceeded 20,000 fish per 24-hour period. In addition, plant procedures at Jaaes A. FitzPatrick required continued impingeraent sampling when limits of the fisn contingency plan were exceeded. The fish contingency plan specified a iaaximura nuaber of individuals for eacn species, based on historical impingenent patterns, which iaight oe expected to be iupinged during one 24-nour sanpling period.

2.2.2 Laboratory Processing Laboratory processing of organisms collected in inapingeaent was conducted as i described for organisms collected with gill nets (see Section 2.1.2).

2.2.3 Data Analysis Data were tabulated to present impingeiaent rates (number and weignt) for each species as well as all species combined. Total estiiaated impingeiaent for eacn month was calculated using the formula:

D=f(X) where c = the number of fish collected during the samplin9 period j v = the volurae of cooling water used during the sampling pe:iod

X = the total monthly volume of cooling water used.

7 The annual impingenent estimate was then calculated by adding the 12 inonthly impingement estimates.

2.3 WATER QUALITY DETERMINATIONS 2.3.1 Impingement Sampling

! At the onset and completion of each impingement sample, discharge temperature

(_+0.5 C) was determined with a bucket of water retrieved from the discharge.

2.3.2 Gill Net Sampling In association with each gill net sample, tenperature and dissolved oxygen were measured at each gill net station (NMPE, NMPP, FITZ, and NMPW) (Table 2-1).

Water was collected with a Keuaerer bottle at the 7.6-meter (25-ft) depth.

Temperatures were determined + 0.5 C).

3. RESULTS 3.1 LAKE ONTARIO STUDIES Tne 1982 Lake Ontario iaonitoring prograsa was designed to describe the coiapo-sition, relative aoundance, and seasonal patterns of fish in the vicinity of tne Nine rtile Point proiaontory. For ease in descricing seasonal gatterns, the months of the year were divided into winter (January througn Maren), spring (April througn June), sununer (July through September), and fall (Octooer through Decemoer). Tne aquatic studies also iaonicored water quality (teraper-ature and dissolved oxygen) in tne collection area. The results obtaisied during the 1982 gill net progra,a using tue saethods and iaaterials descrioed in Chapter 2 follow.

3.1.1 Species Coiaposition 1

Of the 14,395 specimens collected with gill nets froia tne Nine Mile Point study area during 1982, 23 species of fish and one taxa of crustacean were identified (Table 3-1). Alewife accounted for over 80 percent of all fish collected.

Spottail shiner conprised alraost 12 percent of the total catch, rainbow smelt conprised 3.3 percent, and tne remaining 4 percent of the total catch was represented by 21 taxa.

Spottail shiner and white sucker were the only species collected during all months sainpled in 1982. Alewife, brown trout, lake chub, and white perch were collected during seven of the nine saonths sampled. Tne reaaining species were collected in six or less of the months sarapled. The nuraber of species collected each inonth remained between 11 and 13, with toe exceptions of August when 16 different species were caught and October and Deceiaber when only four and eight species, respectively, were collected.

3.1.2 Temporal and Spatial Distribution The tenporal distribution of fish collected by gill nets showed that peak abundance occurred during spring and early sunner; July was tne raonth of highest abundance. Collections of fish dropped in Septeauer and continued low through the fall (Taule 3-1). Alewife was the doiainant species during eignt of the nine iaonths sampled. In Octouer, lake trout was the most nuuerous species collected.

Catch rates (catch per 12-hour set) among che transects ranged froia one fish per 12-hour set to 820 fisn per 12-hour set (Table 3-2). The lowest catcii rate occurred in October at transect NMPE and the highest catch rate was in July at transect NMPW. The annual iaean catch rates for all the transects, ItlPW, HMPP, FITZ, and it1PE were similar in 1982. However, the annual iaean caten rate for the FITZ transect was 5.0-7.7 percent lower than the annual mean caten rate for the other transects.

nine species of fish in the Nine Mile Point area as representative important species (RIS). The species so designated are alewife, brown trout, cono, rainbow saelt, saallinouth bass, spottail shiner, threespine stickleoack, wnite perch, and yellow perch. Of thesa nine species six nave been selected, uecause of their abundance and trophic level, for detailed studies in tne 1982 report.

These six include alewife, rainbow smelt, smallmouth bass, spottail sniner, white perch, and yellow peren. Tne following results relate to the temporal and spatial distribution (catch per 12-nour set) and the lengtu-frequency distribution of the six selected RIS species.

Alewife Gill net catches of alewives were nigh in tne spring and reacned a peak (aean CdtCil rate of 573 fisn) in July. Catches declined rapidly in August and ranained low (mean catch rate less than or equal to 101 fish) tnrougn tue fall (Appendix Taole A-1). These trends are consistent with gill net data fran previous years. Annual mean catch rates for alewife were nighest at transects NMPW, NMPP, and NMPE and were lower at transect FITZ (Taole A-2).

Alewife collected with gill nets during 1982 ranged fraa 105 to 240 inillimeters (an) in total length. Most alewife collected were adult fisn in the 150-190 mm range with a mean length of 172.7 an; tnis size group was most abundant during the spring and summer (Table A-3).

Rainbow smelt Gill net catches of rainbow smelt were highest in early spring and Hovember (mean catch rate greater than or equal to 8 fish). Catenes of smelt declined in late spring and no smelt were collected fran August through October (Table A-1). A large catch of rainbow spelt at transect FITZ in April resulted in the highest annual mean catch rate at tnis transect.

Total lengths of rainbow smelt collected with gill nets ranged from 124 to 254 an; with 163.3 mm as the mean lengtn. Most rainoow snelt collected in the spring were yearling or older and fell within the length intervals of 130-170 mm, whereas rainbow smelt from the fall collections fell within 150-190 an.

However, the mean lengths for rainbow smelt in all iaonths collected were quite silail ar.

Spottail shiner l Spottail shiner were collected with gill nets in each Month saapled during 1982. Low catch rates in the early spring gave way to larger collections in

! the su. Lier and declining catches in tne fall. Annual uean catcan rates were l identical at transects FITZ and NMPE (33 fish per 12-hour set), lower for L transect NMPW (20 fish per 12-hour set), and half tnat value for transect NdPP (1G fish per 12-hour set) (Taole A-2).

Spottail sniners from the gill net collections ranged in length from 97 to 138 na. The mean lengtn was 118.0 an and tne most abundant length interval was 110-130 an, generally adult fish in spawning condition. Approximately 94 percent of the adult spottail sniners caught were collected fran June tnrougn August (Table A-3).

3-5

Saallmouth bass Gill net catches of smallmouth bass were low throughout the year (Table A-1).

The higher catch rates in August and Septeaber were due to relatively large catenes of bass at transect FITZ (5 and 8 fisn per 12-hour set) in those iaonths

, (Table A-2).

1 Gill net collections yielded adult smallmouth bass ranging froia 298 to 456 mm in total length, witn a uean lengtn of 363.4 na. Altnough iaost of the l smallmoutn bass were caught in August and September, tue lengtns were evenly l distributed over five lengtn categories (310-410 sam) (Table A-3) .

l White perch Collections of white perch with gill nets were highest in late spring and

sunner (June through August) (> mean catch rate of 3 fish) and only one wnite i perch was caught in the fall (Table A-1). The iaost nulaerous collections of I

whita perch occurred at transect NMPW during the sunaer months (Table A-2).

White perch collected with gill nets varied from 91 to 311 nn. Almost 75 percent of the white perch caught were adults in the length range of 210-270

na, and the only white percn caught in the fall was a young of the year at 97 nn (Table A-3). ,

Yellow perch Gill net catches of jellow perch were highest (mean catch rates of 2-6 fisn) during the late spring, summer, and in Novenber. Catch rates (Table A-1) were near zero during the cold water samplinj montus in early spring and in October and December.

Yellow perch from gill net collections were fearling to adult and ranged froa 1 142 to 330 mm in total lengtn wito a mean lengtn of 239.7 aa. The most abundant caten for yellow perch occurred in July and approxiuately 45 percent of those individuals were adults between 190 and 230 mm in length (Taule A-3).

3.2 IN-PLAllT STUDIES Nine Mile Point Unit I and Ja.aes A. FitzPatrick power plants have once-through cooling systens with intake and discnarge structures located nearby in Lake Ontario. Aquatic organisms, detritus, and otner decris enter with the water pu. aped from tne vicinity of the submerged intake pipes. These organisms, detritus, and debris are iiapinged on trash racks, which are used for screening out large items, and the traveling screens are used for screening out smaller material s. The traveling screens are backwashed to remove any accumulation of organisms, detritus, and debris into a sluiceway wnich eapties into the impingenent collection baskets. Studies of fish impingement began in the Spring of 1972 at fline Mile Point Unit 1 and in 1975 at James A. FitzPatrick.

The fish impinged at both plants have been taonitored yearly in order to esti-mate abundance and biomass losses for each species.

The objectives of the 1982 impingeaent sampling program were to estimate annual l fish losses, to detenaine sper.ies composition of impinged fisn, and to describe 3-6

l seasonal patterns of fisa frapingenent. In addition, plant operating conditions (Table 3-3 and Appendix Tables B-1 and B-2) were logged during 1982. The results obtained during the 1982 impingement sampling program follow.

l 3.2.1 Nine Mile Point Unit 1 Nuclear Station 3.2.1.1 Species Composition and Estimated Lnpingement Impingaaent sampling at Nine Mile Point Unit 1 during 1982 resulted in the

! collection of 27 taxa. Twenty-six fish species or genera and one invertebrate l species, crayfish, were identified. Rainbow smelt was the most numerous I species collected comprising 66.8 percent of the total catch. Rainbow smelt I

together with alewife and the sculpin family accounted for 90 percent of all the taxa collected (Table 3-4). No single species was caught in all 12 montus.

l Sculpins, which were the most frequently caught taxa, were caught during nine months of tne year. Alewife were caugnt in six months of the year and rainbow smelt in only five launtns during 1982 (Table ti-3).

I Ninety-two percent of tne total biomass collected at Nine Mile Point Unit 1 during 1982 was comprised of gizzard snad, alewife, and rainbow siielt (Taule 3-5). Gizzard shed dominated biomass collections during the winter iaontns.

During the spring, su; amer, and fall months of 1932, fline rtile Point Unit 1 was l

shut down for repairs and impinged few fisn. Therefore, no one species l- dominated uiomass collections. Ratner, the dominant specias, by weignt, in each of the other months was determined by the largest fish caught in tHat month (Table B-4).

The total number of equatic organisms impinged at (11ne Mile Point Unit 1 during 1982 was estimated to be approxiaately 89,526 individuals (Taole B-6). Rainbow smelt were estimated at 59,921 which is 67 percent of the total. Total weight was estimated to be 1,860 kilograms with gizzard shad estimated at 1,409 Kilo-gra:as and 76 percent of the total biomass.

3.2.1.2 Tanporal and Length Distributions January was the month of peak impingeaent at Nine Mile Point Unit 1 in 1982.

However, overall impingement collections were very low in 1982. The fact that Nine Mile Point Unit 1 main circulating.watar pumps were shut down for repairs from March through Deceaber accounts for tne low impingaaent collections.

j Rainbow smelt dominated the winter irapingenent collections, couprising over 60 percent of the total catch during those sonths. Alewife ranked second in abundance in January, accounting for 14.5 percent of tne total catch. Sculpins I

ranked second in abundance in February and March comprising 22.4 and 15.1 l percent, respectively, of the total raontnly catch.

! Lengtn-frequency distributions are given for six representative iuportant species (RIS): alewife, rainbow smelt, spottail sniner, small.aoutn oass, white peren, and yellow perch (Table B-6). Alewife collected in the spring and summer at Nine Mile Point Unit 1 were subadult to adult fisn; a few young-of-the-year alewife were collected in the late summer. Young-of-the-year as opposed to adult rainbow smelt dominated impingement collections in tne mnter.

Adult spottail shiner and adult yellow perch were also collected during this period; whereas the white perch collected in the winter of 1982 were less than one year in age. Few snalliaoutn oass were iiapined.

3.2.2 James A. FitzPatrick Nuclear Power Plant 3.2.2.1 Species Conposition and Estimated liapingement Impingenent saapling at James A. FitzPatrick during 1982 resulted in the col-lection of 48 taxa; 45 fish species or genera were identified. Tnree of the 48 l taxa collected were non-fish species: a mollusk, a crustacean, and an l ampnibian. Alewife and rainbow smelt coaprised approximately 97 percent of tne total frapingement catch (Table 3-6) and were caught in eacn monch saapled.

Also caught in eacn of the 12 months were rock bass and yellow perch. White l perch and spottail shiner were collected during 11 uonths of the year and sculpin and saallmouth bass were found in 10 months (Table B-7).

Alewife comprised 78 percent of the total fish biomass collected in 1982 (Table 3-7). Gizzard shad and rainbow snelt comprised 13.9 percent of tne total bionass. Alewife dominated biomass collections in the spring, sunner, and fall. In January, gizzard shad presented the largest percentage of the total bionass collected. Brown trout comprised rou3nly half of February cistenes, by j weignt; rock bass and gizzard shad codorainated in March (Table B-8).

The total number of aquatic organisms impinged at Jaaes A. FitzPatrick during

, 1982 was estimated to De approximately 603,242 individuals (Table B-9).

Alewife were estiaated at 346,503 whica is 57 percent of the total. The rainbow saelt population impinged in 1982 was estimated at 235,289 (39 percent of the total). Total weight was estimated to be 11,235 kilograns and alewife were esti nated at 8,670 kilograias or 77 percent of the total bioiaass.

3.2.2.2 Teaporal and Length Distributions Periods of peak estimated iupingenent at James A. FitzPatrics in 1982 occurred during the spring and in July and Deceaber. In April and May, adult alewife and subadult to adult rainbow snelt contriouted to the large inapingenent.

July's peak impingenent was composed primarily of adult alewife and, in December, a large collection of young-of-the-year rainbow smelt increased tne estimated impingement numbers. Overall, rainbow saelt dominated tne winter and

[

early spring (>55 percent of total montnly catches) collections. Alewife pre-l vailed during the rest of the spring and sunner (>80 percent of total monthly catches) impingement catches. In the winter months, alewife and rainbow siaelt codaninated the collections, with the exception of Decenber when one large l rainbow smelt collection caused a sharp increase in the impingenent estimates.

White perch, which was the tnird .aost prevalent species impinged in 1982, were caught in large numbers in April (616 fish) and Decenber l(126 fish). Sculpins l were also collected in large numbers in April (545 fisn). Gizzard shad catenes were low (<270) in 1982.

Length-frequency distributions are given for the six representative important species (RIS): alewife, rainbow smelt, spottail shiner, saalliaouth udss, white perch, and yel1ow perch (Taole B-10). Adults were the principal aje yroup of alewife collected in 11 of tne 12 sampling months. In tne late summer (Septenber), young-of-the-year alewife predominated tne collections.

Young-of-the-year alewife were also caugnt in April and August. In contrast to the alewife, the young-of-tne-year age group dominated collections of impinged rainoow smelt throughout most of the year. Only in May did adult rainbow smelt outnumber the young-of-the-year smelt. The majority of white percn collected in the spring were adults; however, about one-third of the white peren measured in April were yearlings.

A few young-of-tne-year whita peren (<55) were collected in the winter and late fall (December). Adult yellow perch were collected ai. James A. FitzPatrick during most of the year with increased occurrence in tne spring and summer.

Few young yellow perch (<20) were collected during 1982. The size of the spottail shiners collected increased during the first nalf of tne year and then I declined in the latter half of tne year: yearling fisn in tne winter gave way to adult fish during the spring and early sunimer and then young-of-the-year fisn in late su. amer ana fall. Adult smallmouth bass were caught throu9nout the spring and suaner. In the fall, only young-of-tne-year saall.aoutn bass were col lected. Generally, at James A. FitzPatrick as at Nine Mile Point Unit 1, adult and subadult fish were impinged during the winter and spring iauntus.

Young-of-the-year fish appeared in impingement samples in the su. amer and doai-nated the fall collections.

3.3 WATER yVALITY 3.3.1 Gill Net Sampling Water teuperature and dissolved oxygen were measured during sampling efforts to indicate the water quality in the vicinity of the Nine Mile Point gill net transects. Collections were made near tne bottom of the 30-ft contour using the uethods and materials described in Chapter 2 of this report.

Water teaperatures taken at the four gill net transects ranged from 2.1 C to 21.4 C during the 1982 sampling program (Table 3-8) and are typical of a north-ern tenperate lake. Temperatures were lowest in April, increased gradually through June, increased rapidly through July and August, to a maxiiaum in mid-August. Water tenperatures declined slightly in Septenber, dropped rapidly in October (possibly as a result of an internal seiche), increased in Noveauer and declined again in Deceaber. Variations of 1 C or more betseen transects were rare in 1982. In April at transect WIPW, the water tenperature was about 4 C higner than the other transects. Influence frou nearoy streams and trioutaries may have contributed to the nigher tenperature.

f Dissolved oxygen (DO) concentrations were greatest (>9.5 ppa) in the spring and fall months when water tenperatures were low (Taole 3-8). Lower D0 values l occurred during the late sumner months wnen water te.aperatures were at tne highest values for the year, reflecting tne fact tnat oxygen solubility decreases with increasing water tenperature. The lowest 00 value recorded was 8.8 ppa un 24 August 1982 at transect FITZ. 00 concentrations were not low enough to cause stress in aquatic organis.as and were not likely to nave influenced distribution.

l 3.3.2 Impingaaent Sanpling Intake and discharge temperatures were masured at the beginning and end of each impingement salaple. Intake temperatures were taken from plant operational logs. Discharge temperatures were measured in the discuarge canal by EA personnel.

Intake tenperatures raeasured by EA on salapling days at Nine Mile Point Unit 1 ranged from a minimum of -0.3 C on 19 and 29 January to a maxilaum of 22.6 C on 20 August. Discharge temperatures (when the plant was operating nedr generating capacity during January through March) on sampling days varied from a los of 20.2 C on 20 January to a high of 24.9 C on 6 and 28 January (Table l B-1).

l At James A. FitzPatrick, intake tenperatures measured by EA on sampling days reacned a minfiauia of -1.1 C on 10 Marcn and a maxirauia of 22.2 C on 20 July.

Discharge tangeratures during plant operation (at least 75 percent of generating capacity) were lowest on 25 March and highest on 17 August. The lowest discharge tenperature .44s 17.7 and the highest was 38.5 C (Taule B-2).

Minimuia and maximuia teaperatures corresponded wita normal seasonal cycles in lake tenperatures.

4. COMPARISON OF SPECIES COMPOSITION AND TEMPORAL DISTRIBUTION FOR FISH COLLECTED IH GILL NETS AND IMPINGEMENT SAMPLES, 1982 Trends in the species composition and te:aporal distribution for fisu collected witn gill nets were generally comparable to trends observed in tne iupingement collections at Nine Mile Point Unit 1 and daues A. FitzPatrick during 19d2.

Differences in these trends were largely due to several factors: the selec-tivity of the gill net year to certain age or size class fisn, seneduled or unscueduled outages at the power plants, and the different lengths of tne sampling seasons.

l Size selectivity of the gill nets may account for soide differences in species l composition between impingenent and gill net collections. Although all of the 24 taxa (23 fish and one crustacean) with the exception of walleye collected with gill nets were present in the impingement collections, more tnan an additional 20 species were caught in impingenent at James A. FitzPatrick.

James A. FitzPatrick impinged 46 species of fisn and Nine Mile Point Unit 1 impinged 27 species of fish. Many species such as sculpins, darters, and sticklebacks were too small to be caught in the gill nets used.

Size selectivity of the gill nets and absence of winter gill net sampling also explained a difference in tenporal abundance of fish between gill nets and impingement collections. Gill net collections (catch per 12-hour set) of fish were hignest in spring and early sunvaer with peak catenes coinciding with the spawning runs of seyeral fish species. The highest impingement collections (number per 1,000 mJ of water pumped) for Nine tiile Point Unit 1 were in January (Figure 4-1) and for James A. FitzPatrick during early winter and late fall (January and December), spring (April and May),. and midsummer (July) montns (Figure 4-2). The impingenent abundance peaks in January reflected large collections of rainbow smelt. Because gill nets were not collected in January, coincidental peaks were not observed. A large collection of youn9-of-the-jear raisibow smelt in December contriouted to the impingenent peak at James A. Fitzpatrick. Gill nets do not effectively caten young-of-the-year fish, therefore, no similar abundance peak was observed in the December gill net catch.

A power plant outage can obscure the usual trends in tne temporal distrioution of impingenent catenes. For example, few fish were impinged at Nine Mile Point Unic 1 from Marcn through December during tne outage. In past years, hign numbers of alewife were impinged in the spring. Data from the Spring 1982 gill net collections reflected this crend as large numbers of alewife in spawning condition were caught. Spring collections of alewife in 1982 at James A.

FitzPatrick and in gill nets compared similarly. In both types of collections, adult alewife dominated the spring catches.

Another factor that made comparison of gill net data and impingement data difficult was the different lengths of the sampling seasons. Gill net collec-tions were made in nine months, April through December, wnereas impingeaent sampling was conducted year-round. In terms of species composition some fish species, for example whitefish and gizzard shad, were present and/or abundant during winter impingement samples but were absent or poorly represented in the Nine Mile Point area during the gill net sampling season (spring througn fall).

The gill net sarapling did not catch as many different species nor did it have identical temporal distribution patterns as did impingement collections.

Rainuow smelt, which were doininant in tne winter impingeuent collections, were not dominant in any uonth in the gill net catches.

Despite the differences mentioned above, the trends in species composition and tenporal distribution were similar for gill nets and impingenent collections.

Almost all of the same spacies collected with gill nets were also found in impingenent samples. In terms of nunerical abundance, alewife daninated both gill net and James A. FitzPatrick irapingenent catches. Rainbow smelt, wnich dominated Nine Mile Point Unit 1 impingenent catches, were second in abundance at Jeaes A. FitzPatrick and third in abundance in gill net catches. Taking into account the size selectivity of gill nets, temporal distribution patterns l between impingement and gill nets were similar. Spring and summer ilnpingement abundance peaks at Jaines A. Fitz atrick (composed raainly of alewife) coincided with gill net peak catenes (also mainly alewife). Spottail sniner were col-lected at James A. FitzPatrick and in gill nets for most of the sampling season. Rainbow smelt were present in higher numbers in the early spring and in the fall than during tne sunaer. Generally, these trends were evidence tnat species occurrence and abundance is largely due to temperature preference and migrations of spawning fish populations, and that subadul; and adult fisn are collected in the winter and spring wnile young-of-the-year fisn are Mainly caught in the summer and fall.

l S. ENVIROTEENTAL IMPACT ASSESSMENT

5.1 INTRODUCTION

Aquatic ecology studies were initiated for Nine Mile Point Unit 1 in the late 1960s and for J&aes A. FitzPatrick in mid-1975. These studies were designed to evaluate potential effects to the aquatic environment from power plant opera-4 tion in the vicinity of the Nine Mile Point promontory. A third nuclear station, Nine Mile Point Unit 2, is now under construction at this site.

The 1982 report is submitted to fulfill requirements of Niagara Mohawk Power i Corporation and the Power Authority of the State of New York as amended by Ene

! U.S. Nuclear Regulatory Commission in the Spring of 1979 to assess any environ-i mental impact. If total monthly impingement catches deviate from tne daily ranges as specified in Section 3.1.2 of the Nine Mile Point Unit 1 Environ-mental Technical Specifications (Table 5-1) or exceed the monthly maximun limit '

by greater than 50 percent as specified in Section 4.1.1-B of tne James A.

FitzPatrick Enviromental Tecnnical Specifications (Table 5-2), a discussion of

-events is to be included in the annual report. The results of impingement and -

gill net studies are detailed in Chapter 3 and discussed with respect to the effects of plant operation on the fish community.

5.2 IMPINGEMENT COLLECTIONS AT NINE MILE POINT UNIT 1 NUCLEAR STATION AND JAMES A. FITZPATRICK NUCLEAR PLANT, 1982 Periodic collections of impinged fish nave been conducted at Nine Mile Point Unit 1 since 1972 and at Janes A. FitzPatrick since~ 1975. The species compo-sition of impingement collections in 1982 was similar to tnat observed during the past years' impingement catches. Between 37 and 48 fisn species have been caught at Nine Mile Point Unit 1 in the past years. This year's collection of 26 fish taxa was lower than previous years and may be attributed to the fact tnat main circulating water pmaps were shut down during repairs for most of the year. At Jaaes A. FitzPatrick, impingement studies nave yielded between 43 and 54 fish species per year. The 1982 study resulted in the collection of 44 fish taxa.

hnpingement catches have consistently been dominated by alewife. However, there are two exceptions: in 1978 -threespine stickleuack was the dominant species and in 1979 rainbow smelt was tne dominant species. Rainbow saelt has been second in abundance during most years except in 1976 when threespine stickleoack was second in abundance and in 1979 when rainbow smelt was dani-nant. During 1982, alewife daninated impingement collections at James A.

FitzPatrick power plant constituting over 60 percent of the total catch.

During the tnree months of operation, January through 16 Marcn, at Nine tiile Point Unit 1, rainbow snelt was the dominant species constituting 66.8 percent of the total catch. Rainoow smelt was second in abundance during 1982 at James A. FitzPatrick accounting for 36.6 percent of the total caten, and alewife was second in abundance at Nine Mile Point Unit 1. White peren was the third most abundant species at James A. FitzPatrick with 0.5 percent of the total caten, and sculpins were third in abundance at Nine Mile Point Unit 1 witn 10.6 percent of the total catch. Threespine stickleback was low in aoundance at both power plants during 1982.

In terras of uloiaass, alewife has been the doiainant species during most years of impingenent study. Gizzard shad dominated biomass collection in 1978 because of an abundance of large individuals. Rainbow snelt nas been either second or third in dominance with other species such as smallmouth bass, unite perch, or rock bass dominating in other years. During 1982, alewife was the daainant species, in terms of biomass, at James A. FitzPacrick and second in weight at Nine Mile Point Unit 1. Gizzard shad was the dominant species by weight at Nine Mile Point Unit 1 and third in dominance at James A. FitzPatrick. Rainbow smelt was the second dominant species, by weignt, at Jaraes A. FitzPatrick and third in dominance at Nine Mile Point Unit 1.

Estimated annual impingenent at both power plants has been nia n ly variable over

! the years. Estimated annual impingenent at Nine Mile Point Unit 1 froia 1974 to i 1981 ranged froia a low of 135,000 fisn in 1977 to a nign of 3.4 iaillion fisn in 1976. James A. FitzPatrick annual estimated impingement ranged from 244,000 fish in 1979 to a high of 4.3 million fisn in 1976. Impingeaent estimates for 1982 were low compared to estimates for previous years. Nine Mile Point Unit 1 impinged 89,526 organisms; Janes A. FitzPatrick impinged 603,242 organisms. In canparison to tne standing stock estimates (O'Gonaan and Bergstedt 1983, personal communication) for the two iaost abundant iiapinged species, alewife (4 to 4.5 billion) and rainoos smelt (0.5 billion), tne nwabers isapinged at either power plant represented a negligible portion of tne fish coimaunity of Lake Ontario.

5.3 OCCASIONS WHEll SPECIFIED LIMITS WERE EXCEEDED During 1982, the average daily catch at Nine Mile Point Unit 1 was lower than the established daily ranges in March through July and October through Decenber (Table 5-1). Nine Hile Point Unit 1 main circulating water puiaps were shut

down from Maren through Decenber and therefore few organisins were impinged.

However, in January, tne estaDlished daily inapingeaent range was exceeded. Tne January impingement catch was approximately three and one-half times greater than the specified range. Of the total fish collected in January, over 68 percent were rainbow smelt, and of the total rainbow staelt collected, over 95 percent were young-of-tne-year fisn. According to the Oswego Fisn and Wildlife Station (FWS) (O'Gonaan and Bergstedt 1982, 1983 personal coumunication), the rainbow smelt population has oscillated during recent years resulting in nigner recruitment of saelt during the odd years. Impingenent cata on young-of-tne-year rainbow smelt collected during the 1981 and 1982 winter seasons at toe Nine Mile Point power plants was comparable witn the FWS data. Collections of rainbow saelt at both Nine Mile Point Unit 1 and Jaiaes A. FitzPatrick during l

the 1981 winter (EA 1982) were low (1,202 and 2,539, respectively). Young-of-i the-ystar saelt, whicn were spawned in spring 1980, caaprised a los percentage (less than 20 percent) of the total smelt caten. However, during the winter of 1982, the catches of rainbow smelt at outn power plants were nign and young-of-the-year sidelt, spawned in spring 19dl, couprised a nigh percentage (arouna 95 percent) of tne total smelt catch.

Established monthly liiaits at Jaaes A. FitzPatrick were exceeded oy 50 percent in Julf and Decemoer 1982 (Table 5-2). In July, large collections of alewives caused the monthly limics to be exceeded. At this time of the year, alewife move insnore in large nunbers to spawn. Gill net data collected in spring and early suniner 1982 pointed to a large spawning population of alewife in the vicinity of the Nine Mile Point promontory. In addition, one impingement 5-4

collection on 22 July contained almost 42 percent of the total fish collected for the montn. In December, one large collection of young-of-the-year rainbow smelt caused the monthly limits to be exceeded. The impingenent collection of 30 Decenber contained over 86 percent of the total fish collected for the monch. Of the fisn collected, over 93 percent were rainbow smelt and over 90 percent of the smelt caught were young-of-the-year fish. One very large collection can introduce a considerable bias to monthly impingement estimates if it is included in calculation of the saean iaontnly impingeaent collection.

Since large impingenent collections typically have oeen associated witu short-lived meteorological phenosaenon, an alternate method can be used to esti-mate the Decenbar total: the total nunber collected on 30 Decenber was added to i the estimate for the other 30 days of Decenber wnich was based on tne other m five 24-hour saaples collected that month. By this method the estimated impingenent for Decenber 1982 was approximately 40,000 as canpared to 118,508 l- using the mean of all six 24-hour sanples.

l The high impingement on 30 Decanber 1982 may be attributed to unusually high west winds of about 40 knots during the sampling period. Previous studies at the Nine Mile Point power plants have indicated that higher rates of impinge-ment may occur during specific weather conditions, such as nigh winds froia tne west or northwest. Studies oy Ecological Analysts, Inc. in the vicinity of Nine Hile Point have supported these observations. For exanple, on 25 and 2G

! e August, the wind blew fran the west to northwest at 15-40 knots. The impinge-ment collection at Jaaes A. FitzPatrick on 26 August constituted over SG

percent of cne total collection for that month. On four other dates Lin 1981 l (29 Septenber and 29 Decenber)'and 1982 (5 April and 26 August)] west ur north-west sinds exceeded 25 knots and impingenent collections were greater than on

! adjacent sampling dates witn lower wind velocity.

! Invironmental factors other than strong winds may also lead to higner impinge-

. ment at the power plants. Biological factors sucn as population size, migra-l tion patterns, scnooling, and spewning behavior in conjunction witn environ-l mantal factors such as water teaperature, currents, heavy waves, and plant operating parameters could affect innpingenerit. Migrations of large populations of adult alewife and rainbow smelt during the spring and early suaner seasons are triggered by responses tar certain environmental and biological conditions.

As tne water temperature of the lake increased,- tnese two species inove insnore to spawn. The high impingeaent of adult alewife and rainuow sinelt during spring and early sunmer has been well docunented at the Nine Mile Point power plants and elsewhere. Spigarelle et al. (1982) noted similar results at tnree power plants on Lake Michigan. After spawning, the adult fish iaoved offshore L to . deeper, cooler waters' and were impinged in fewer nunbers at tne power

plants. In- sumaer and early fall, the younJ-of-the-year alewife and rainbow n sdelt tended to renain insnore and appeared in the impingement collections, sonetimes in large nur.Ders. During late fall and_ early winter, alewife and Jrainbow smelt congregated at deep and midwater depths, respectively, in Lake

- Ontario (O'Gorman and Bergstedt 1983, personal caanunication). In 4ddition, "fran observations by Ecological Analysts, other fish species, such as wnite perch, although not as nuinerous as a)ewife and rainbow smelt, exnibited similar

-seasonal patterns of occurrence in tne impingenent collections.

Althcugh seasonal lake tenperatures, spawning behavior, and population size l were major factors contributing to high impingenent, other factors could alsc cause increases in impingement. Brandt et al. (1980) discussed the possibt.lity r \

5-S t

)

that the most abundant fish species in Lake Michigan were positioned at dif-ferent temperature strata to reduce competition for food resources. Shifts in the thermocline could cause fish to adjust their position in the water column.

In addition, schools and aggregates of certain fish species could induce localized increases in population densities of fish in the lake. O'Gorman and Bergstedt (1983 personal communication) noted that insnore schools and aggre-gates of fish can disintegrate at night and scatter throughout the water column. Because of tne forementioned influences on fisn behavior, it is possible tnat individual fisn or whole schools of fish could become more sus-

)

ceptible to impingement. Incidences of high impingeraent iaay not, therefore, De .

the direct result of power plant operation, but may have been caused by D10109-ical benavior of fish in canbination with external enviromaental influences.

5.4 EFFECTS OF POWER PLAliT OPERATION AT HINE MILE POINT ON THE FISH COMMUNITY One of the five Great Lakes in Nortn Aaerica, Lake Ontario is roughly oval in shape, 190 miles long, and 53 miles wide. The lake was fonaed by extensive l glaciation-some 10,000 years ago. It nas a surface area of 7,340 square uiles l with an average depth of 250-300 (TI 1978). Historically, Ldke Ontario Was l listed as an oligotrophic lake with tne principal offshore fish stocks con-sisting of coregonines, lake trout, and burbot (Christie 1974). Lake Ontario as well as tne otner Great Lakes have undergone some extensive biological changes. Lamprey invasion, overfisning, and cnanging water quality nave played an important role in the fish species and fish population shifts and changes through the years. Introduction of the alewife in tne 1870s and tne rainbow smelt in 1912 added additional pressure to the changing natural fisn consnunity.

l Aquatic collections in the vicinity of Nine Mile point have been in progress since the 1960s through 1982. During the 1960s and early 1970s, studies on the

' current flow patterns and aquatic populations were conducted by Dr. J.F. Storr under contract to Niagara Mohawk Power Corporation. From 1973 tnrough early 1977, Lawler, Matusky, and Skelly Engineers (LMS) employed gill nets, trawls, seines, and fish traps in Eneir survey of the Nine Mile Point nearfield. Texas Instruments (TI) continued sampling with various gears until'early 1979 wnen the current sampling prograa utilizing gill nets at four selected transects was initiated. Ecological Analysts has conducted this saapling progran since 1981.

In addition, trawls were conducted by the New York State Department of Environ-mental Conservation (NYSDEC) in the spring of 1977 (Elrod et al.1978) and by the U.S. Fish and Wildlife Service (FWS) and NYSDEC in 1978,1979 (Elrod et al .

1979, 1980), and'1980 and 1981 (O'Gorman and Bergstedt 1982, 1983 personal conaunication) .

Previous data collected by gill net suggest that the fish comaunity structure in the Nine Mile Point vicinity during any given year varies seasonally fron one of low species diversity during the winter and early spring to one of nigh species diversity from spring to fall. However species composition in the vicinity of Nine Mile Point has enanged little during the nine years of power plant operation. A total of 23 taxa of fish were collected during the 1982 gill net prograa. Collections during 1979,1980 and 1981 yielded 18 to 20 taxa. The similarity indices (Pinkham and Pearson,1976) Detween years were l consistently greater than 0.75 (wnere .1.0 indicates identical collections) indicating a relatively nigh level of similarity in the species composition of the fish conununity saiapled by gill nets between 1979 and 1982 (Table 5-3). Tne 5-6 l

occurrence of certain daainant species in gill net collections coincided with either spawning benavior (e.g., rainbow suelt and trout percn during spring and brown bullheads in summer) or tenperature preference (e.g., lake trout during spring and fall and rainbow smelt in fall). In contrast alewife, spottail sni-ner, and white sucker are ubiquitous, appearing througnout the sampling season.

Although species composition remained fairly constant, variations in the size of fisn populations nave been observed tnrougnout Lake Ontario, as well as

. localized fluctuations. Alewife and rainbow smelt, two species which doainate the fisn comiaunity in the vicinity of Nine Mile Point in terms of abundance, have exhibited distinct oscillations in population size. Christie (1974) using

experimental gill nets showed annual oscillations, which could vary ten-fold, i in the size of the spawning run of the alewife froia 1958 to 1970. Christie l

(1974) also correlated certain peaks in the gill net data with significant mortalities along the lakeshore. In the vicinity of the Oswego Steam Station in Oswego, New York, Lawler, datusky and Skelly Engineers (LMS 1975) reported fluctuations in natural concentrations of the alewife population by as mucn as 800 percent fraa year to year. LMS (1977) also reported tnat populations of alewife in the vicinity of fline Mile Point vary by as mucn as half an order of magniude. An important factor in the fluctuations in alewife aoundance appears ,

! to be periodic large die-offs of tue alewife stocks during the spring, possibly due to low temperature shock (Granam 1956, in ColDy 1971) reported since their introduction in the Great Lakes. In recent years the greatest numbers were recorded in 1974 and 1976 (LMS 1975, 1977). According to the FWS and tiYSUEC (Elrod et al. 1979,1980), the population of alewife declined because of a die-off during tne severe cold winter of 1976-1977. Losses were estimated as high as 60-75 percent of tne population in tne vicinity of the Nine Mile Point 4 promontory. This population decline was reflected by decreasing catenes of

alewife in impingement collections from 1975 tnrough 1978 wnich were not only recorded at Nine Mile Point power plants, but also at Ontario Hydro power '

stations in Canadian waters (TI 1981). According to tne FWS (O'Gonaan and Bergstedt 1983, personal connunication), lakewide populations of alewife increased through 1981 and then decreased slightly during 1982 as a result of a probable die-off during the winter of 1982 Increases in the adult alewife population in the 1982 gill net catches and impingenent collections at James A. FitzPatrick were local and did not correspond to tne lakewide population reduction as noted by the Oswego FWS.

Large impingement collections of young-of-the-year. alewife during August through October 1981 at the Nine Mile Point power plants were not experienced at the Ginna or Russell power plants near Rochester, New York (Dakin 1982, personal communication). Local fluctuations in the size of spawning alewife populations collected by gill nets are not unique to the Nine Mile Point vicinity but have also been recorded in the Bay of Quinte in Lake Ontario froa ~ ,

1958 to 1972 (Christie 1974). The size and condition of future alewife stocks would most likely be influenced uy climatic conditions and possfuly by tue

! numbers of salmonids stocked (0'Gonnan and Bergstedt 1982, 1983 personal conaunication).

Rainbow smelt populations have also displayed some oscillations in tne Great Lakes fran year to year. Introduced in 1912 in Lake Micnigan, populations of rainbow smelt became abundant in Lake Ontario in the late 1940s (Christie 1974). Tnis species nas also oeen noted to suffer large population losses

.possibly as a result of. disease (Van Oosten 1947, in Scott and Crossman 1973),

j 5-8

as noted in Lake Huron and Lake Michigan in 1942-1946 and in Lake Erie as recently as 1969 (Scott and Crossman 1973). Rupp (1968, in Kireneis and Stanley 1981). snowed ten-fold variations in rainbow saelt abundance during the spawning runs in Branch Lake, Haine over an 8-year period. Commercial yield of rainbow snelt (christie 1974) was noted to decline in Lake Ontario froni 1960 through 1970 and then increase after 1970. Studies by NYSDEC and FWS indicated an eleven-fold increase in rainbow saelt populations from 1972-1978 (TI 1981).

Yearly oscillations in the lakewide rainbow s.aelt population were noted by the biologists at the Oswego Fish and Wildlife Station (O'Gorman and Bergstedt 1982, 1983 personal comaunication). As gill net collections of rainbow saelt over the past four years were low when compared to population estimates and, because no age measureaent determinations of tne adults were iaade, a population j trend in the vicinity of Nine Mile Point cannot oe identified clearly.

However, the nuinber of snelt caught by gill nets in cne vicinity of Nine Mile Point nas shown an increase from 1979 (TI 1980) wnen only 103 rainuow suelt were caught coinpared with 466 rainbow snelt in 1981 (EA 1982) and 473 rainoow smelt collected in 1982. In conclusion, gill net surveys in the Nine dile Point vicinity during 1982 did not reveal any significant changes in the area's smelt populations. Nevertheless, increases in the local population of alewife were observed. RainDow Saelt also are not evenly distributed in Lake Ontario.

The FWS estimated that nearly half the rainbow suelt in all U.S. waters of Lake Ontario were concentrated around Cape Vincent (TI 1981).

Thus it appears that changes in relative abundance of fish populations in the vicinity of Nine Mile Point are the result of fluctuations in natural mortality and variation in both localized and lakewide spawning success of various species which compose the local fish community. Such oscillations in popula-tion size of various species should not be confused with community instability in an ecological sense. Stability has numerous definitions and connotations with respect to ecosystaas but very generally refers to the ability of a system to remain relatively similar to itself in the presence of perturbation (Levin 1975). That is stability is some measure of the response of a systen and its

! ability to oscillate aoout and return to some " equilibrium state." Therefore a i certain level of fluctuation in population size among various species in a canmunity is inherent in the concept of stability as an ecosysten responds to changes or extranes in natural and anthropogenic factors in the biotic and abiotic environment.

No long-tena trends toward reductions in the major fisn population in the

vicinity of Nine Mile Point have been apparent. The observed fluctuations in population size appear to nave occurred over a range within the ability of those populations to maintain themselves. Tne success of these populations will most likely be determined by natural environmental factors (e.g.,

temperature, disease) and man-induced changes in the tropnic structure (e.g.,

salmonid stocking programs).

5.5

SUMMARY

Impingement of fish oy Nine Hile Point Unit 1 and James A. FitzPatrick power plants appears to have little affect on the fish community structure or fish population size in the vicinity of Wine Mile Point or on the entire Lake 5-9 l

)

Ontario aquatic ecosystem. Impingernent of fisn at the power plants tends to affect the populations in the manner of a stationary predacor, as discussed by Voigtlander (1980); tne fish populations can generally adapt to the predator.

Species conposition in tiie vicinity of Nine Mile Point has shown little

-variation from year to year. Natural biological factors sucn as Habitat and teaperature preference, schooling, and migration behavior play an important role in seasonal variations in species occurrence or absence. Oscillations in fish abundance reflect the biology of species coupled with interactions anong species and variable environmental factors. While certain fish species around Nine Mile Point, such as alewife and rainDow smelt, exhibit wide fluctuations in population size, other species, such as white sucker, renain fairly static.

I

! In conclusion, no alterations to the existing fish couinunity or population levels occurred as a result of power plant operation in the Nine dile Point area during 1982 based on the impingenent study. No incidents of cold snock to fish due to shutdowns at either plant were reported or observed during 1982.

No rare, endangered, or tnreatened fish species were collected in the 141ne flile Point area during 1982.- No Corbicula sp. mollusks were found in the 1982 impingement collections at Nine Mile Point Unit 1 or Jaaes A. FitzPatrics power plants. High ispingaaent estimates at Nine Mile Point Unic 1 in January 1982 reflected a large recruitment of young-of-tne-year rainbow saelt. Hign impingeaent estimates at James A. FitzPatrick in July 1982 reflected a large local spawning population of alewife and in Decenber 1982 reflected one lerge, wind-induced catch of young-of-the-year rainbow smelt. Finally, no unusual or high occurrence of diseases, parasites, or other abnormalities were noted on the fisn collected in tne Nine Mile Point vicinity during 1982.

C-1 EXCEPTION TO STANDARD OPERATING PROCEDURES FOR IMPINGEMENT AT NINE MILE POINT UNIT 1 NUCLEAR STATION 13 JAN 1982 Rescheduled Impingement Sample - During the impingement saiaple, traveling screen No. 11 Decame inoperable. It could not be determined when the screen shut down, thus an accurate impinge-ment rate could not be calculated. The sample was rescheduled and completed on 15 January 1982.

NOTE: No impingement samples were missed during the 1982 sampling season. The sample was rescheduled using a randomly selected day as required by the Environmental Technical Specifications.

C-2 EXCEPTIONS TO STANDARD OPERATING PROCEDURES FOR IMPINGEMENT AT JAMES A. FITZPATRICK NUCLEAR POWER PLANT 29 JAN 1982 Time Delay in Starting Inpingenent Sample - Maintenance work on the traveling screens prevented wasning the screens at the scheduled onset of the impingement saaple. Washing of the traveling screens and sample initiation were accomplished at 1700 hours0.0197 days <br />0.472 hours <br />0.00281 weeks <br />6.4685e-4 months <br /> and the impingeaent sample was terminated 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> later.

9 JUL 1982 Rescheduled Impingenent Sample - Cleaning of the water boxes inadvertently introduced fish that were not part of the impinge-ment sample into the collection basket. The sample was rescheduled and completed on 20 July 1982.

10 AUG 1982 Rescheduled Impingenent Senple - A full scale test of the radiological emergency response system limited access to the power plant on the scheduled impingenent collection day of 11 August. The sample was rescheduled and completed on 10 August 1982.

NOTE: No impingement samples were missed during the 1982 sampling season. All samples were rescaeduled using randomly selected days as required by the Environmental Technical Specifications.

C-3 EXCEPTIONS TO STANDARD OPERATING PROCEDURES FOR GILL NET SAMPLING JUN 1982 The second gill net collection required by Nine Mile Point Unit 1 Technical Specifications could not be accomplished on the last two scheduled impingement days in June due to bad weather. A gill net set made on 30 June 1982 was voided because a tangled net reduced tne fiso caten. A successful 9111 net set and collection was made on 6-7 July 1982; weather conditions prevented gill net sampling between 30 June and 6 July.

l 19 Juli 1982 Weatner conditions: West to nortnwest winds at 15-25 knots, Wdves building to 3-5 feet, showers or thunderstonas, snall craft advisory issued.

29 JUN 1982 Weather conditions: Northwest winds at 10-20 knots, waves to 1-3 feet, hazy, huiaid, tnunderstorus, dense fog settled over lake.

DEC 1982 The gill net collection for Decenber could r.ot be accolaplished on tne first two scheduled impingenent dates because of Dad weatner. Since weather conditions are generally adverse and unpredictable during Decenber on Lake Ontario, the final gill net collection was scheduled and completed on tue next day witn favorable weatner conditions,14-15 Deceaber 1982.

7 DEC 1982 Weather conditions: West winds at 20-30 knots, waves to 5-8 feet, cloudy witn snow possible.

13 DEC 1982 Weather conditions: South to southwest winds at 15-25 knots, waves to 3-6 feet, fair weather.

APPENDIX 0 CONDITION OF FISH: ABNORMALITIES, DISEASES, AND EXTERNAL PARASITES Fish collected in the impingement and gill net samples were checked for any outstanding abnormalities, diseases, or external parasites and for general physical condition. Nineteen species from impingement and six species from gill nets were found to have some kind of abnormality or affliction.

Rainbow smelt and sculpins fran impingement collections were most commonly found to have afflictions. Sculpins exhibited an internal abdominal twnor characterized by one or nere small white sacs. Fungus (Saprolegnia) affected rainbow smelt caught in February, March, April, Fby, June, and October. Other abnormalities observed on rainbow smelt sere: two occurrences of a twnor-like infection of the intestine, one occurrence of " popeye" (projection of eye),

four occurrences of "pugnose" (deformity of snout), six occurrences of scoliosus (curvature of spine), and vertical lacerations on sides of body during April and May.

The three most common afflictions affecting other fish species were fungus, lamprey, and other scars, and black spot infection (characterized by small black spots scattered on body and fins). Black spot infection was noticed on white sucker, golden shiner, yellow perch, central mudminnow, enerald shiner, and pumpkinseed. In most cases, only one specimen of each species was found with the infection. Fungus affected a few individuals of each of the following species: gizzard shad, white perch, yellow perch, brown trout, trout perch, rock bass, snallmouth bass, and alewife. An occasional lamprey scar was observed on white sucker, brown trout, and rainbow trout in the impingement collections and on brown trout, lake trout, and a rainbow smelt from gill net collections. Other incidents of disease affected a variety of species. Two white perch exhibited " popeye." A spottail shiner and white sucker had a tumor-like growth on their bodies. A rock bass from gill net collections had "pugnose."

0verall, the physical condition of the fish collected in impingement and gill nets was healthy. However, alewife in the August impingement collections appeared emaciated. Some gizzard shad exhibited heamornaging around the head, and nine lake trout from gill net collections had scars or lacerations on their bodies. All of the aforementioned diseases, abnonnalities, and presence of scars are naturally occurring and do not generally result from power plant l operation.
