EXECUTIVE SUFdMARY This report, prepared by EA Engineering, Science, and Technology, presents the results of impingement abundance studies conducted during 1994, as required by the State Pollutant Discharge Elimination System (SPDES) Permit No. NY 000 1015,Section IV.C (dated 1 July 1983) for the Nine Mile Point Nuclear Station Unit 1 (NMP Unit 1).

Impingement abundance was monitored between 4 and 20 samples per month, for a total of 78 samples from January through December 1994.

Two brief outages occurred in April (8 days) and July (5 days) at NMP Unit 1.

Both main circulating water pumps were shut offduring the outage in July.

Impingement sampling at NMP Unit 1 in 1994 resulted in the collection and identification of 33 fish taxa.

One taxon (sculpin) was identified to the genus level and the remaining 32 taxa were identified to the species level.

Crayfish and zebra mussels were the only invertebrates found in the impingement collections in 1994.

Mudpuppy, an amphibian, was collected in an impingement sample in May 1994.

Alewife was the most numerous (38,323) comprising 81 percent of the total fish catch (47,127 excluding fragments).

Alewife, threespine stickleback, and trout-perch accounted for 90 percent (42,540) of all fish collected (47,127).

No rare, endangered, or threatened fish species were collected at NMP Unit 1 in 1994.

Zebra mussels (Dreissena polymorpha) were identified in the Nine Mile Point area in late Summer 1990.

Zebra mussels were first noted in the impingement sample collections in late 1991, and their presence (by volume) has been noted on applicable data sheets as part of the regular impingement sample analysis procedure since that time.

No Corbicula sp. mollusks were found in the 1994 impingement collections at NMP Unit 1.

1. INTRODUCTION Nine Mile Point Nuclear Station Unit 1 (NMP Unit 1) is solely owned and operated by Niagara Mohawk Power Corporation.

The station is located on a 900-acre site in Oswego 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 designed and manufactured by the General Electric Corporation, and a 610,000-kilowatt (net electric) turbine-generator.

NMP Unit 1 has been operational since December 1969.

The station is a critical, integral part of the New York State Energy Master Plan, and a cost efficient source of electrical energy withinNiagara Mohawk Power Corporation's service area.

NMP Unit 1 utilizes a once-through, non-contact cooling water system to dissipate thermal energy from the main condensers and auxiliary cooling systems.

Cooling water is drawn from Lake Ontario by means of two main circulating water pumps rated at 946.25 m~ (250,000 gal) per minute (total) and two service water pumps which operate at approximately 68.13 m'18,000 gal) per minute (total). Usually, one service water pump is operating except during the mid-summer months.

I The lake intake structure is an open-sided hexagonal concrete structure located in approximately 5.5 m (18 ft) of water (mean lake level) and approximately 259 m (850 ft) 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 m (335 ft) from the shoreline and 3.8 m (12.5 ft) below the surface (mean lake level).

Aquatic organisms, detritus, and other debris enter with the water pumped fr'om the vicinity of the submerged intake structure.

These materials flow through trash racks, which are used for removing large items, such as logs, and'are impinged on a total of three traveling screens constructed of 9-mm (0.375-in.) mesh, 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 sluiceway which empties into an impingement collection basket.

The aquatic organisms impinged at NMP Unit 1 have been monitored since 1972 in order to estimate species abundance and composition.

This report presents the results of the biological monitoring program conducted by EA during 1994, as required by the State Pollutant Discharge Elimination System (SPDES) Permit No.

Impingement 'sampling at NMP Unit 1 in 1994 resulted in the collection and identification of 33 fish taxa.

One taxon (sculpin) was identified to the genus level and the remaining 32 taxa were identified to the species level.

Crayfish and zebra mussels were the only invertebrates found in the impingement collections in 1994.

Mudpuppy, an amphibian, was collected in impingement samples in May 1994.

Alewife was the most numerous species (38,323) comprising 81 percent of the total fish catch (47,127).

Alewife, threespine stickleback, and trout-perch (42,540) accounted for 90 percent of all fish collected (47,127 excluding fragments).

Zebra mussels (Dreissena polymorpha) were identified in the Nine Mile Point area in late Summer 1990.

Zebra mussels were first noted in the impingement sample collections in late 1991.

Their presence has been noted (by volume) on impingement sample data sheets whenever applicable.

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. mollusks were found in the 1994 impingement collections.

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

In accordance with permit requirements, 78 impingement collections were scheduled between 1 January and 31 December 1994 as listed below:

78 (a)

Days assigned within each month were selected randomly using the formula (I+INT(RAND~31))

from Lotus 1-2-3, Release 2.3.

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

As required by the SPDES permit, selected sample dates were scheduled such that no more than 10 days occurred between samples.

When rescheduling samples became necessary,'every attempt was made to reschedule the samples to accommodate the 10-day requirement.

Table 2-1 lists the scheduled sampling dates.

In 1994, a total of 78 impingement samples were successfully collected.

Three impingement samples had to be rescheduled due to maintenance work involving the traveling screens.

One impingement sample had to be rescheduled due to a Clam-Trol treatment process in the intake/traveling screen area. Allsamples were successfully completed over the rescheduled sample periods.

Details of the rescheduled samples are available in Appendix A.

2.2 SAMPLING PROCEDURE '(PERMIT SECTION IV.B.2P,4)

Sample collection was initiated at approximately 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 approximately 5 minutes.

(Traveling screens may also be rotated and washed during the 24-hour sample period as part of the normal programmed wash cycle.)

The collection basket 2-1

l

with a 3.2-mm (0.125-in. stretched mesh) liner was then positioned at the end of the sluiceway.

The collection basket remained in place for the duration of the sample period, unless high impingement or debris loads required that it be emptied.

For such occasions, it was removed, emptied, and repositioned.

At the end of the 24-hour period, the traveling screens were rotated and washed for approximately 5 minutes.

Impinged organisms were washed 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 water flow rates, intake and discharge temperatures, and power production (Appendix B). When relevant to data analysis, intake water volumes are noted on the report tables.

Additionally, volume of water through the intake is apportioned for the time(s) when main circulating water pumps are operating or shut off("A" and "B" columns on applicable tables).

A subsampling routine was utilized for occasions when high impingement rates or high debris loads were encountered.

The subsampling technique was based on volume, and the total 24-hour catch was estimated using the formula; Est' dN "F'h '

Volume of Total Samplex No. of FishinSubsample Estimated No. ofFish in Total Sample Volume ofSubsample The total volume of the sample was determined by repeatedly fillinga volumetrically 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.

A subsample volume of at least 25 percent of the total sample volume was mathematically calculated.

Aliquots of the sample were randomly selected, removed, and measured to determine their volumes.

Aliquots were removed and combined until the required subsample volume was achieved.

When subsamples occurred in 1994, they constituted at least 25 percent by volume of the total sample.

Fish and invertebrates contained in the subsample were then processed according to regular laboratory procedures (Section 2.3).

2.3 LABORATORYPROCESSING (PERMIT SECTION IV.B.4)

Once the impingement sample was collected, it was returned to the laboratory and 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 scientific names is included in Appendix C.

Specimens (to a maximum of 25 individuals) of the following species were analyzed for length and weight: white perch, alewife, and rainbow smelt. Allcollected specimens of smallmouth bass, yellow perch, and salmonids were weighed and measured.

Other species present in the samples were enumerated and weighed to obtain a total count and total weight for each species (or lowest taxonomic level).

Total lengths were measured to the nearest millimeter. For the purposes of this report, 100 millimeters was used as a determinant of size class differentiation between young-of-the-year (YOY) and adults based on size range information in Scott and Crossman (1973).

Weights were measured to the nearest 0.1 g for specimens less than 10 g, to the nearest 1.0 g for specimens between 10 and 2,000 g, and to the nearest 25 g for specimens over 2,000 g based on the precision of the scales used for measurement.

When possible, measurements were recorded with greater accuracy than required (e.g., to the nearest 0.1 g for specimens between 10 and 2,000 g) ifthe scales would allow. Any unusual conditions, abnormalities, or presence of fish tags were noted on the data sheets.

2.4 WATER QUALITYDETERMINATIONS(PERMIT SECTION IV.B)

Intake and discharge temperatures were recorded from the station operating records and are presented in Appendix B.

2.5 DATAPRESENTATION (PERMIT SECTION IV.C)

Data are presented according to the requirements set forth in the SPDES permit:

a.

Monthly and annual total of impingement by species and grand total over all species.

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 volume of water pumped on sampling days..

3. RESULTS AND DISCUSSION 3.1 IMPINGEMENTABUNDANCEAND COMPOSITION (PERMIT SECTION IV.C.3)

In 1994, the seasonal patterns of fish species diversity and abundance were evident during the course of impingement sampling at NMP Unit 1.

Impingement abundance at NMP Unit 1 increases in the spring, corresponding to the migration of alewife, rainbow smelt, and other spawning species inshore.

Impingement abundance then decreases for the summer months as adult fish complete spawning and move offshore.

During this time, larval and juvenile fishes have not attained a size susceptible to the impingement process.

YOY generally reach an impingeable size in the late summer and autumn.

Impingement abundance of YOY then increases sporadically due to the frequency of late summer and fall storms and the inability of YOY to avoid the intake structure during storms.

Impingement at NMP Unit 1 continues to be less than historically observed and appears to be influenced by record low alewife biomass in Lake Ontario first noted in 1992 (Lange and Smith 1992).

The collections of impinged fish at NMP Unit 1 for 1994 followed the historical seasonal pattern:

April and May impingement collections increased in volume as fish came inshore to spawn followed by a decrease through late spring and summer (Table 3-1). Impingement increased slightly in November as a result of storm conditions coinciding with the presence of fish near shore.

Samples collected in January and December 1994 also reflect winter storm conditions and the presence of YOY near shore.

The largest fish impingement collections occurred in April (4,278) and May (41,561), accounting for 97 percent of the total 1994 fish impingement collections.

Alewife (38,323) continued to dominate annual impingement collections as in most previous years, accounting for 81 percent of the annual fish impingement totals for 1994.

Threespine stickleback (2,175), trout-perch (2,042), and spottail shiner (1,568) were also in abundance in the impingement samples (none are representative important species [RIS]). AllRIS combined (alewife, rainbow smelt, yellow perch, smallmouth b'ass, white perch, lake trout, brown trout, and Atlantic salmon) equaled 40,522 individuals, excluding fragments, and 86 percent of the annual impingement total. Historically, rainbow smelt are often second in abundance in the impingement, however, on occasion other species'opulations increase to replace rainbow smelt in rank as threespine stickleback did in 1994.

Daily impingement sample results for 1994 are presented in Appendix D.

In 1994, fish species diversity occurred in accordance with seasonal abundances and/or behavioral stimuli.

Species diversity ranged from a low of 6 species in July (partial station outage) to a high of 22 species in April. Low species diversity occurred in June, July, September, October, and December.

Generally, low diversity results from station outages (July) and periods with little meteorological or behavioral influence on fish populations in the vicinity of NMP Unit 1.

The highest diversities occurred in January, February, April, May, and November.

Species diversities in April and May correlate to inshore movements of many species toward their spawning grounds.

Species variety in January, February, and November illustrates the effect of storm conditions on young fish that remain in nearshore areas.

When 24-hour impingement collections coincide with storms, the size of the impingement sample may be several orders of magnitude larger than other samples for the same month (e.g., Appendix D - January and February).

In previous years, high rates of impingement occurred at NMP Unit 1 when strong winds from the west or northwest resulted in heavy wave action.

Lifton and Storr (1977) statistically correlated wave height, water temperature, and wind with impingement at power plants on Lake Erie and Lake Ontario.

Wave height was found to be the most significant factor contributing to the correlation.

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 rate of impingement.

YOY of most species of fish appear to be most susceptible to meteorological influences (Lifton and Storr 1977). In 1994, storm conditions influenced the size of the impingement collections on several occasions and are described further:

An impingement sample collected over the 24-hour period of 20-21 January resulted in the collection of 48 percent of the monthly impingement total.

The sample also contained 58 percent of the month's collection of rainbow smelt.

Winds were from the west at 15-25 knots which resulted in rough water.

In February, west winds of 20-30 knots occurring over the period 2-3 February resulted in the collection of 56 percent of the month's collection of rainbow smelt and 54 percent of the sculpins collected for the month.

In April, an impingement sample collected from 17 to 18 April contained 58 percent of the month's impingement total.

The sample also contained 46 percent of the month's collection of alewife, 68 percent of rainbow smelt, and 51 percent of threespine stickleback.

Winds were from the west 15'-30 knots and waves. of 5-8 ft.

An impingement sample collected over the 24-hour period of 29-30 August resulted in collection of 52 percent of the month's impingement abundance and 77 percent of the month's collection of rainbow smelt.

The winds were from the northwest at 15-20 knots and waves were 3-5 ft, Temporal presence or absence of species throughout 1994 followed seasonal behavior and meteorological influence.

Alewife and rainbow smelt were collected in 7 and 11 months of the year, respectively.

Alewife dominated the impingement collections in 3 of those months.

Rainbow smelt dominated the impingement collections made in January and February, months when alewife were absent from the samples.

Smallmouth bass and yellow perch, both RIS, were collected in 6 months of the year, and their occurrence is considered relatively common in the collections.

White perch, also an RIS, were collected during 5 months of 1994.

3-2

The salmonids (lake trout, brown trout, and Atlantic salmon) were collected sporadically during the year.

Non-RIS found commonly and in relative abundance throughout the seasons of 1994 include threespine stickleback, trout-perch, spottail shiner, stonecat, and sculpins.

Rates of impingement were calculated using two different methods, The mean daily impingement rate (Table 3-2) is defined as the average number of fish collected per day per month and is included for comparison.

The mean daily impingement rate based on flow (Table 3-3) is defined as the total number of fish impinged on sample days in the month divided by the volume of water pumped in million cubic meters (MCM) during those days.

Each table defines the rate per species per month and the total impingement rate for the month.

Impingement rates per MCM in Table 3-3 are further specified into columns "A"for the time period when at least one main circulating water pump was operating and "B" when only the service water pumps were operating (July 1994).

Rates of impingement, whether calculated over time (Table 3-2) or volume (Table 3-3),

generally demonstrate the same trends detected in the actual impingement collections, In the spring, rates peak as fish migrate inshore then decrease through the summer.

In autumn and winter, the rates of impingement increase in response to the occasional influx of YOY during storms.

When the main circulating water pump(s) were operated a portion of the time, the impingement rate per volume was higher when the pumps were operating than when only the service water pumps were running (e.g., July).

Fish impingement rates may be reflective of meteorological, environmental, and behavioral influences on fish movements near NMP Unit 1 regardless of water volume.

However, the volume of water pumped through the intakes willmirror these influences most when both main circulating water pumps are operating.

The mean daily impingement rate determined by volume (Table 3-3) was highest in April (198 fish/MCM) and May (1,421 fish/MCM). These impingement rates are reflective of adult alewife movements to inshore spawning areas.

Other months when increased impingement rates occurred were January (57 fish/MCM), February (47 fish/MCM), and November (51 fish/MCM), reflective ofthe,influx of YOY during, storm conditions.

If The lowest rates of impingement (when at least one main circulating water pump was operating) occurred in August (8 fish/MCM), September (4 fish/MCM), and October (2 fish/MCM). Weather conditions for the samples were relatively mild with no major storms, thereby reducing any meteorological influences on the fish impingement.

The collection of a particular species on a seasonal basis is also reflected in the daily rate of impingement.

The rates of impingement for April, May, and June are a direct result of alewife movements inshore.

Rainbow smelt also increased in rate of impingement in April and May as the result of inshore spawning movements.

Several species, including threespine stickleback, spottail shiner, and trout-perch, also increased in rate of impingement in April and May in response to their species-specific spawning behavior.

Threespine stickleback were prevalent during Spring 1994, to the extent that they replaced rainbow smelt as second in abundance.

Seasonal meteorological events, particularly winter storms, influenced the daily rate of impingement in the manner already addressed for Table 3-1.

The effects of storm conditions are particularly evident on the collection of several RIS during 1994:

alewife 3-3

I (November), smallmouth bass (November), and rainbow smelt (January, February, and November).

Non-RIS influenced by winter storms include bluegill (November) and threespine stickleback.

Generally, the monthly impingement rates based on flow volume (Table 3-1) willreflect the collection of fish at times of seasonal abundance and/or under storm conditions.

Calculations of the estimated number of organisms impinged at NMP Unit 1 during 1994 were based on the mean daily impingement rate (Table 3-4) and on the rate of impingement adjusted for flow (Table 3-5).

Estimates are similar for both methods of data expression.

Estimates of impingement based on daily average rate (Table 3-4) are given for comparison.

Based on volume, the estimated number of fish impinged was 82,358 (excluding fragments and crayfish).

The estimated annual impingement of alewife was calculated as 60,973 equaling 74 percent of the annual total.

The number of rainbow smelt estimated impinged in 1994 was 5,796 (7 percent of the total).

The RIS fish estimates were impinged in the following numbers:

white perch, 315; yellow perch, 270; smallmouth bass, 289; lake trout, 155; brown trout, 17; and Atlantic salmon, 3. AllRIS fish combined (67,818) comprised 82 percent of the annual estimated fish impingement.

For 1994, the estimated impingement generally followed the seasonal and meteorological patterns previously discussed.

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

Length-frequency distributions are determined in Tables 3-6a through 3-6f for the following species:

alewife, rainbow smelt, white perch, yellow perch, smallmouth bass; and the salmonids (lake trout, brown trout, and Atlantic salmon).

Length frequency for species such as alewife and rainbow smelt which are collected throughout the year generally follow a seasonal pattern.

Adults and subadults (>100 mm; >4 in.) of both species are most often collected during spring months when spawning migrations move adult fish to shallow, inshore waters.

Late summer and fall collections are primarily composed of YOY (<100 mm; <4 in.)

which are found in shallow inshore nursery areas.

(Scott and Crossman [1973] noted the late summer length attained by alewife as 5.1-75 mm [2-3 in.] and that of rainbow smelt as 51 mm

[2 in.].) At times during the year, YOY of,both species were collected damaged to an extent that made it impossible to accurately obtain length measurements on individual fish (i.e.,

August, October, and November).

(During the fall season, some'of these fish may have originated from the service water strainers and may not have been collected directly from impingement.)

In 1994, collections of alewife followed the seasonal length distribution pattern as described (Table 3-6a).

Alewife collected from April through July were adult and subadult fish. From August through December, all alewife collected were YOY. Alewife measured from samples collected in 1994 were comprised of 85 percent adults and subadults and 15 percent YOY.

The minimum length measured was 3.8 cm (1.5 in.); the maximum length recorded was 20.3 cm (8.1 in.).

Rainbow smelt collections in 1994 (Table 3-6b) were dominated by adults and subadults in April and May.

Overall, YOY rainbow smelt comprised 23 percent of the smelt measured.

The minimum length recorded was 3.8 cm (1.5 in.); the maximum length recorded was 21.9 cm (8.8 in.).

t ii l

White perch (Table 3-6c) measured from the 1994 impingement samples were predominantly YOY (77 percent).

Adult white perch were collected as individuals and were collected primarily in April and May. The minimum length measured for white perch was 5.3 cm (2.1 in.); the maximum length recorded was 29.9 cm (12.0 in.),

Yellow perch (Table 3-6d) were collected sporadically throughout 1994.

The yellow perch measured during impingement collections at NMP Unit 1 were comprised of 65 percent adults/subadults.

The minimum length measured was 5.3 cm (2.1 in.); the maximum length was 27.5 cm (11.0 in.) Yellow perch appear to have had a few seasons of successful spawning as evidenced by the increased number of YOY and subadults in the impingement samples (EA 1993, 1994).

Preliminary assessment data on yellow perch captured by National Biological Service trawls during the early 1990s also indicate successful spawning (O'Gorman 1993, 1995).

Smallmouth bass (Table 3-6e) collected during 1994 were predominantly YOY (75 percent) and were collected sporadically through the year with occasional increases due to meteorological influences (November).

The minimum length recorded for smallmouth bass collected in 1993 was 3.7 cm (1.5 in.); the maximum length recorded was 45.2 cm (18.1 in.).

Lake trout and brown trout (Table 3-6f) were only collected as adults in 1994.

The minimum length measured was 63.8 cm (25.5 in,); the maximum length measured was 79.0 cm (31.6 in.) for lake trout. Brown trout were recorded on three occasions during the year.

The minimum length recorded was 44.8 cm (17.9 in.); the maximum length recorded was 54,1 cm (21.6 in.). Two Atlantic salmon (Table 3-6f) were collected in May as fingerlings and were likely from recent stocking in the vicinityof NMP-1. The miiiimum length recorded was 14.8 cm (5.9 in.); the maximum was 15.9 cm (6.4 in.).

3.3 BIOMASS (PERMIT SECTION IV.B.4)

The total biomass (Table 3-7) collected. in the 1994 impingement samples at NMP Unit 1 was 969,571 g (970 kg), excluding invertebrates and fragments: 'Alewife accounted for 773,816 g (774 kg) or 80 percent of the annual total biomass.

Alewife and rainbow smelt (14,506 g; 14.5 kg) combined with the other RIS (white perch, 5;273 g; yellow perch, 5,463 g; smallmouth bass, 6,355 g; lake trout, 63,114 g; brown trout, 4,464 g; and Atlantic salmon, 56 g) comprised 90 percent of the annual total biomass at NMP Unit 1 ~ Biomass is generally more widely distributed among species collected since a few heavy-bodied fish (i.e., trout, basses, etc.) may weigh more than a more abundant fragile-bodied species such as rainbow smelt.

The estimated biomass (excluding fragments) (Table 3-8) calculated based on flow volume was 2,281,809 g (2,282 kg) of which alewife constituted 54 percent (1,226,756 g; 1,227 kg).

Alewife, rainbow smelt, and the other RIS collected in 1994 accounted for 80 percent (1,835,257 g; 1,835 kg) of the annual estimated biomass (excluding fragments).
