l. INTRODUCTION

(

The Nine Mile Point (NMP) Nuclear Station Unit 1 is solely owned and operated J by Niagara Mohawk Power Corporation. The station is located on a 900-acre site l in Osvego County, New York, and is approximately 6.8 miles north-northeast of the City of Oswego. The power conversion system utilizes a 1,850-megawatt thermal boiling water reactor (BVR) designed and manufactured by the General l Electric Corporation, and a 610,000-kilowatt (net) turbine-generator.

NMP Unit 1 has been operational since December 1969. The station is a critical, integral part of the New York State Master Energy Plan and, with the exception of installed hydroelectric capacity, the station is one of the most cost efficient sources of electrical energy within Niagara Mohawk's service area.

f NMP Unit I utilizes a once-through, non-contact cooling vater system to dissi-pate thermal energy from the main condensers and auxiliary cooling systems.

CoolingwaterisdrawnfromLakeOntariobymeansoftwomaincirculatingwater pumps rated at 946.25 m (250,000 gallons) pgr minute and two service water pumps which operate at approximately 68.13 m (18,000 gallons) per minute (total). Usually, one service water pump is operating except during the mid-summer months.

The lake intake structure is an open-sided hexagonal concrete structure located in approximately 5.5 meters (18 feet) of water and approximately 259 meters (850 feet) from the existing shoreline. The lake discharge structure is of a design that is similar to the intake structure. This structure is hexagonal with open-sided ports and is located approximately 102 meters (335 feet) from

[ the shoreline and 2.6 meters (8.5 feet) below the surface (lovest expected lake i

level).

Aquatic organisms, detritus, and other debris enter with the vater pumped from the vicinity of the submerged intake structure. Organisms, detritus, and debris flov through trash racks, which are used for removing large items, such as logs, and are impinged on traveling screens, which are used for screening out smaller materials. Periodically, the traveling screens are rotated and washed to remove any accumulation of impinged organisms or other material into a sluicevay which empties into an impingement collection basket. The aquatic organisms impinged at NMP Unit 1 have been monitored yearly since 1972 in order to estimate species abundance and composition.

This report presents the results of aquatic ecological studies conducted by EA Science and Technology, a Division of EA Engineering, Science, and Technology, Inc. during 1986 as required by the State Pollutant Discharge Elimination System (SPDES) Permit No. NY 000 1015,Section IV (dated 1 July 1983) covering Niagara Mohawk Power Corporation's NMP Unit 1.

Impingement catches (as required by Section IV.B of the permit) were monitored on a frequency of 4-9 samples per month from January through December 1986 (a total of 51 samples in 1986).

Impingement sampling at NMP Unit 1 in 1986 resulted in the collection and identification of 31 fish taxa. One was identified to the family level and I was identified to the genus levels the remaining 29 vere identified to the species level. Two invertebrates (crayfish and clam) were also represented in the 1986 collections. Alevife was the most numerous (16,075) comprising 66 percent of the total catch. Alevife, rainbov smelt, white bass, and sculpins accounted for 95 percent (23,125) of all fish collected (24,264).

As required by correspondence from Niagara Mohawk Power Corporation to the Nuclear Regulatory Commission, all fish impingement samples are checked for the presence of the Asiatic clam (Corbicula sp.). No Corbicula sp. molluscs were found in the 1986 impingement collections.

2. METHODS AND MATERIALS 2.1 SCHEDULE (PERMIT SECTION IV.B.1)

In accordance with permit requirements, 78 impingement collections were scheduled br.tveen 1 January and 31 December 1986 (Table 2-1). Samples were collected over a 24-hour period on randomly selected days. Randomly selected sample dates were scheduled such that no more than ten (10) days occurred between samples. Table 2-2 lists the scheduled sampling dates.

In 1986, 51 of the 78 scheduled samples were successfully completed (Appendix A). From 9 March 1986 to 19 June 1986, NMP Unit I was shutdown for refueling and maintenance. During the outage, the main circulating water pumps and the traveling screens were shut down for extended periods of time. Whenever the screens were operating, attempts were made to collect impingement samples regardless of whether the main circulating water pumps were operating, although the SPDES permit (No. 0001015 Section IV.B.1) does not require sampling when the pumps are shut down. Maintenance on the traveling screens, coupled with the shutdown of the main circulating water pumps, prevented sample collections in April 1986. A total of 9 of 20 scheduled samples were collected in May 1986. During May, scheduled sample dates were often changed to conform with circulating water pump and traveling screen operating conditions at the station. In June, one sample was rescheduled due to additional maintenance associated with the outage. This sample was rescheduled and successfully collected on another date in June (Appendix A).

2.2 SAMPLING PROCEDURE (PERMIT SECTION IV.B.2,3,4,5)

Samples were initiated around 1300 hours0.015 days <br />0.361 hours <br />0.00215 weeks <br />4.9465e-4 months <br /> of the sampling day. At the beginning of the sample collection period, the traveling screens were rotated and washed for five minutes. The collection basket, with a 9.5-mm (3/8-in.) stretch mesh l liner, was then positioned at the end of the sluiceway. The collection basket remained in place for the duration of the sample, unless high impingement or debris loads required that it be emptied, in which case it was removed, emptied, and repositioned.

At the end of the 24-hour period, the traveling screens were rotated and vashed for five minutes. The impinged organisms were vashed into the collection basket; the basket was removed and emptied.

Plant operational data were obtained from station records for each sample date to document cooling vater flow rates, intake and discharge temperatures, and power production (Appendix B).

A subsampling routine was utilized for occasions when high impingement rates or high debris loade vere encountered. The subsampling technique was based on volume, and the total 24-hour catch was estimated using the formula:

Estimated No. of Fish = Volume of Total Sample x No. of Fish in Aliquot in Total Sample Volume of Subsample 2-1 1

( The volume of the total sample was determined by repeatedly filling a volume-I trically graduated container, recording the values, and adding them. The total volume was thoroughly mixed by hand or with a shovel and spread out evenly over a flat surface. An aliquot (s) of the total sample was randomly selected and

{ this portion of the sample was removed and measured to determine its volume.

During 1986, subsamples constituted at least 25 percent by volume of the total

{ sample. The fish in the subsample were then processed according to regular laboratory procedures (Section 2.3).

2.3 LABORATORY PROCESSING (PERMIT SECTION IV.B.4)

After the impingement sample was collected, it was returned to the laboratory and all organisms were sorted, identified, and enumerated. Identification was made to the lowest possible taxonomic level, which was usually species. For the convenience of the reader, common names are used in the text; however, a list of common and their associated scientific names are included in Appendix C.

Specimens (to a maximum of 25 individuals) of the following species were analyzed for length and weights white perch, alevife, rainbov smelt, small-mouth bass, yellow perch, and each species of salmonid. Any other species present in the collections were enumerated and weighed to obtain a total count and total weight for each species (or lovest taxonomic level).

Total lengths. vere measured to the nearest millimeter. For the purposes of this report, 100 millimeters were used as a determinant of size class differ-entiation between young of the year and adults based on size range information f in Scott and Crossman (1973). Veights were measured to the 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 conditions, abnormalities, or presence of fish tags were noted on the data sheets.

2.4 VATER QUALITY DETERMINATIONS (PERMIT SECTION IV.B.5)

Intake and discharge temperatures were recorded from the station operating conditions listed in Appendix B.

i.5 DATA PRESENTATION (PERMIT SECTION IV.C)

In ake and discharge water temperatures were recorded from the plant operating corditions listed in Appendix B.

Monthly "mean" is equal to the total number of fish impinged by species on all sampling days in a given month divided by the total number of sampling days.

Anaual "mean" is equal t0 the total number of fish impinged by species on all sampling days in the yeat divided by the total number of sampling days in the year.

Total estimated impingement for each month was calculated using the formula:

D h (x) where D - total estimated impingement c = the number of fish collected during the sampling period v . the volume of cooling water used during the sampling period x - the total monthly volume of cooling water used.

The annual impingement estimate was then calculated by adding the 12 monthly impingement estimates.

3. RESULTS 3.1 IMPINCEMENT ABUNDANCE AND COMPOSITION (PERMIT SECTION IV.C.3) k Impingement sampling at NMP Unit I during 1986 resulted in the collection of 31 fish taxa; 1 was identified to the family level, 1 was identified to the

[ genus level, and 29 vere identified to the species level. Two invertebrates I

(crayfish and clam) were also represented in the 1986 collections (Table 3-1).

Alevife was the most numerous species, comprising 66 percent of the total l catch. Alevife, together with rainbow smelt, white bass, and sculpins, comprised 95 percent of the total catch for 1986.

In 1986, due to station outage conditions, temporal distributions of species collected were observed for only 11 months of the year (no samples were collected in April). Rainbov smelt were found in the collections from all 11 months. Alevife were collected in 9 months, absent only during the vinter f (February and March) collections. The other representative important species (RIS), white perch, yellow perch, and smallmouth bass, vere collected during 8, 6, and 5 months, respectively. White perch, yellow perch, and smallmouth

{ bass were generally collected during the fall and vinter months (January -

March October - December). Four species of salmonids (brown trout, lake trout, rainbow trout, and chinook salmon) were collected in January. Brown trout were also collected in June and December, lake trout in October, and l chinook salmon in May. Two species (spottail shiner and sculpin) were found in

' 10 of the 11 months sampled.

{ SMcles diversity in 1986 was highest in the fall (October, November, and December) and vinter (January). The highest species diversity occurred in January when 30 taxa vere collected. The lowest diversity occurred in September when 4 taxa vere collected.

{

Generally, greater impingement collections occur during the spring and early summer months as adult fish (particularly alevife and rainbov smelt) migrate inshore to spawn. Impingement abundance then decreases through the summer as the adults finish spawning and move offshore into deeper, cooler water.

Impingement rates increase again in the fall and vinter as young-of-the-year

{ (YOY) become susceptible to impingement. The predominance of YOY at this time can be associated with the r.ovement of large schools of YOY from their inshore nursery areas to overvintering grounds in the deeper waters of Lake Ontario.

Previous samples in the vicinity of NMP (EA 1982, 1983, 1984, 1985, and 1986) have indicated that the rates of impingement can also be affected by specific meteorological conditions such as high vinds from the vest or northvest, and f resulting vave action. These conditions seem particularly influential to YOY.

At NMP Unit 1, the above stated meteorological conditions occurred in October (sample of 16-17 October) and November (2-3 Novembet). On 16-17 October, vest

{ vinds of 10-20 knots and 2- to 4-ft waves resulted in the collection of Y0Y clevife. In November, 15- to 25-knot vinds from the southwest, which changed f 3-1

to the northwest during the sample period (vave height was 5-8 feet), resulted 1

in the collection of 81 percent of YOY alevife for the month. Lifton and Storr (1977) found statistically significant correlations between environmental factors (vave height, vater temperature, and vind action) and impingement at power plants on Lake Erie and Lake Ontario. Vave height was correlated at a

{ higher level than either of the other factors. They hypothesized that wave-induced turbulence and possibly turbidity interfere with a fish's normal

[

ability to detect and avoid an intake structure, resulting in a higher I impingement.

In 1986, a station outage occurred from 8 March - 20 June at NMP Unit 1. The

( main circulating water pumps were shut down for extended periods, consequently reducing impingement rates at a time when abundances vould have been high. The greatest impingement collections occurred in August, October, and November when YOY (Section 3.2) dominated the collections.

{

Rainbov smelt dominated impingement samples in January,(57 percent), February l

(72 percent), and December (62 percent). White bass dominated the samples in l March (42 percent). Alevife dominated the samples from May through November, ranging from 52 percent (August) to 97 percent (September and October) of the total monthly collections.

( The mean daily impingement rate (Table 3-2) was highest during the late summer (August) and fall (October and November) which corresponded with the actual impingement abundances reporteu for 1986 in Table 3-1.

Impingement rates based on flov (Toble 3-3) were slightly lover than the mean daily impingement rates expressed in Table 3-2. The exception is the data for f March where the impingement rate based on flov is higher than the mean daily impingement rate. Differences are primarily due to the differences in the manner of data expression. The impingement rate based on flov is expressed by volume (number of fish per million cubic meters) of circulating water pumped.

{ Outage conditions when little or no vater is pumped and changes in the volume of water pumped during day-to-day station operations vould influence the

impingement rate expressed by this method. In March 1986, NMP Unit 1 began an l outage for refueling and maintenance. A relatively small volume of water was pumped during the month which increased the rate of impingement based on flov for March.

( The estimated number of aquatic organisms impinged at NMP Unit 1 (based on daily average rate) was 163,522 (Table 3-4). The estimate of impinged organisms based on flov was 160,861 (Table 3-5). The differences in the two estimates may be attributed to the two bases from which the estimations were made and the influence of station operating conditions and weather on data collected. Overall, the estimates on Tables 3-4 and 3-5 are significantly lover due to the u.heduling of an extended outage during the spring (April, Hay, and June) when impingement is highest for species such as alevife and rainbov smelt. Estimated annual impingement of alevife for 1986 vas 110,152 and 108,309, respectively, for both methods (estimate by daily average rate precedes estimate by flov). These values represented 67 percent of the total estimated annual impingements (for both methods) in 1986. Estimated 3-3

impingement of rainbov smelt was 39,837 and 39,517 (24 and 25 percent),

[ respectively, for the two methods of determination. Estimated impingement for the other RIS collected in 1986 are as follows: yellow perch (179; 179), white perch (1,030'; 1,025), and smallmouth bass (372; 369). Annual impingement of the salmonid species was estimated as follows: brown trout (40; 37), lake trout (39; 39), chinook salmon (22; 13), and rainbow trout (8; 8). Both methods of calculation arrived at identical estimates for some of the species j (yellow perch, lake trout, rainbow trout). The small numbers of individuals I impinged vere probably a factor in the resulting equivalent estimations.

3.2 LENGTH DISTRIBUTIONS (PERMIT SECTION IV.B.4)

Length frequency distributions are given for nine representative important species (RIS): alevife, rainbow smelt, smallmouth bass, white perch, yellow perch, and salmonid species (brown trout, rainbow trout, lake trout, and chinook salmon) in Tables 3-6a through 3-6f. Alevife collections were dominated by adults and subadults from May through August. YOY alevife dominated impingement samples from October through December. Collections of alevife in January and September vere limited to only a few individuals, all of which were adults. No samples vere collected during a station outage in April.

Adult and subadult rainbov smelt dominated the smelt collections in the vinter n

(January, February, and March) and late fall (November and December). Collec-tions of rainbow smelt from May through August vere dominated by YOY. In some

[. months, particularly August, September, and October, the YOY rainbov smelt were 1 damaged and the required number of individual length measurements (25) could not be obtained accurately. In September, 23 rainbov smelt were collected, however, none were measurable.

In 1986, 89 percent of the white perch collected vere YOY. Collections of white perch in January and December were 89 and 91 percent YOY, respectively.

Yellow perch were generally collected as adults and subadults. Five YOY vere collected in December impingement samples.

Smal'Lmouth bass were collected as adults with the exception of 3 YOY collected in January, March, and December.

( The salmonid family was represented by brown trout, rainbow trout, lake trout, and chinook salmon at NMP Unit 1 in 1986. All brown trout collected vere collected as adults. One lake trout collected was a parr-marked YOY, the other was an adult. One parr rainbov trout was collected. In May, chinook salmon vere collected as parrs. One adult chinook salmon was collected in January.

3.3 BIOMASS (PERMIT SECTION IV.B.4)

Total biomass collected in the 1986 impingement samples at NMP Unit 1 was 211,013 grams (211 kilograms). Alevife (66,473 grams, 66 kilograms) comprised 32 percent of the total biomass for 1986. Smallmouth bass (28 kilograms, 3-8 s

13 percent), rainbov smelt (17 kilograms, 8 percent), gizzard shad

[ (16 kilograms, 7 percent), and burbot (14 kilograms, 7 percent) were second through fifth in rank, respectively, by veight (Table 3-7).

Estimated biomass for rainbov smelt was 121,940 (9 percent); for gizzard shad the estimated biomass was 119,378 grams (8 percent); and burbot was 108,502 grams (8 percent) of the total estimated ,

biomass. Biomass is generally more videly distributed among the species collected since a few heavy-bodied fish (basses and perches) can weigh more than larger numbers of the more fragile-bodied alevife and rainbov smelt.

3.4 VATER QUALITY (PERMIT SECTION IV.B.5)

Intake and discharge temperatures were recorded in the station operating conditions and are listed in Appendix B. The intake temperatures ranged from 0.0 C on 1 January 1987 to a maximum of 23.1 C on 5 August 1987. The discharge temperatures ranged from a minimum of 0.2 C on 24 January 1987 to a maximum of 39.6 C on 9 August 1986. These temperatures may have occurred on additional days, however, the dates given are the first date of occurrence for minimum and maximum temperatures in the intake and discharge at NMP Unit 1.

t APPENDIX A EXCEPTIONS TO STANDARD OPERATING PROCEDURES FOR INFINGENElfr AT NINE MILE POINT NUCLEAR STATION UNIT 1,1986 01 APR - 23 NAY Void Impinsement Samples - In 1986, 51 of the 78 scheduled samples were successfully completed. From 1 April to a 23 May, the traveling screens were inoperable (due to t required maintenance during an outage) and no samples could be collected. During this time, the main circulating water pumps were shut down and, according to SPDES Permit No.

0001015 Section IV.B.1, sampling was not required. Samples were rescheduled as soon as the traveling screens were operable, regardless of whether the main circulating water pumps were operating. Rescheduled samples were collected on every available date from 23 May to the end of the month.

Nine of the 20 scheduled samples were collected in May.

None of the scheduled samples for April were collected.

11 JUN Void Impintement Sample - At the time of collection on 11 June, tte impingement sample was declared void as a result of work conducted on valves and the shutdown of the main circulating water pumps. The traveling screens were unable to be washed. The sample was rescheduled and successfully collected on 17 June.

APPENDIX D COLLECTION EFFICIENCY (PERMIT SECTION IV.B.6)

To assess the efficiency of the. traveling screens in removing impinged crganisms from the circulating water intake system at NHP Unit 1, a collection efficiency study was conducted on 7-8 November 1984. Since collection officiency is a function of species and their respective sizes, and at no one time during the year are all species and size classes available to the impingement process, representative fish of each of the selected species and size classes to be tested were saved and frozen following routine impingement cnalysis. Species tested were alevife, rainbov smelt, white perch, yellow perch, and smallmouth bass (Table D-1).

t. The fish to be tested were thaved and marked using a visible dye (Rose Bengal) l cnd a fin clip, then sorted into size classes according to the following l

ranges:

Size Class It less than 10.0 cm II: 10.1 - 15.0 cm III:. 15.1 - 20.0 cm IV: greater than 20.1 cm The marked fish were released in the intake canal prior to the traveling screens and at a point below the surface of the water. The release was made at the beginning.of a regularly scheduled impingement sample immediately following the pre-wash. The results of the efficiency test are presented by species and size class in Table D-1.

The percent efficiency ranged from 67 percent to 100 percent. Size Class I

, fish (all species combined) had a mean collection efficiency of 94 percent i

(range: 88-100 percent). Size Class II fish had a mean collection efficiency of 89 percent (range: 67-100 percent). Size Class III fish had a mean collection efficiency of 88 percent (range: 80-92 percent). Size Class IV white perch were recovered at an efficiency of 93 percent. Overall collection officiency for all species and size classes combined was 91 percent.
