0 EXECUTIVE SUKGIARY This report, prepared by EA Engineering, Science, and Technology, presents the results of impingement abundance studies conducted during 1993, 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 1993.

A brief refuel outage occurred from 20 February to 17 April 1993 at NMP Unit 1. Both main circulating water pumps were usually shut off during the outage, though for brief periods, at least one main circulating pump was operating. The seasonal increase in fish impingement diminished during the outage due to the reduction in water volume.

Impingement sampling at NMP Unit 1 in 1993 resulted in the collection and identification of 28 fish taxa. One taxon (sculpin) was identified to the genus level and the remaining 27 taxa were identified to the species level. Crayfish and zebra mussels were the only invertebrates found in the impingement collections in 1993. Alewife was the most numerous (53,592) comprising 96 percent of the total fish catch (55,976 excluding fragments). Alewife, rainbow smelt, and spottail shiner accounted for 98 percent (54,993) of all fish collected

~ ~

(55,976). No rare, endangered, or threatened fish species were collected at NMP Unit 1 in

~

1993.~

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. molluscs were found in the 1993 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 mi 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 within Niagara 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 gal) per minute (total) and two service water pumps which operate at approximately m'250,000 68.13 m'18,000 gal) 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 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 from 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 comprised of 9-mm (3/8-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 1993, 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 collections (as required by Section IV.B of the permit) were monitored on a frequency of 4-20 samples per month from January through December 1993 (a total of 78 samples in 1993).

Impingement sampling at NMP Unit 1 in 1993 resulted in the collection and identification of

~

28 fish taxa. One taxon (sculpin) was identified to the genus level and the remaining 27 taxa

~

were identified to the species level. Crayfish and zebra mussels were the only invertebrates found in the impingement collections in 1993. Alewife was the most numerous species (53,592) comprising 96 percent of the total fish catch (55,976). Alewife, rainbow smelt, and spottail shiner (54,993) accounted for 98 percent of all fish collected (55,976 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. molluscs were found in the 1993 impingement collections, 1-2

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

In accordance with permit requirements, 78 impingement collections were scheduled between 1 January and 31 December 1993 as listed below:

Number of Sampling Days Month Scheduled Per Month" January 4 February 4 March 4 April 16 May 20 June 4 July 4 August 6 September 4 October 4 November 4 December 4 Total 78 (a) Days assigned within each month were selected randomly using the formula (1+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 1993, a total of 78 impingement samples were successfully collected. One impingement sample had to be rescheduled due to a Clamtrol treatment process in the intake/traveling screen area. The sample was successfully completed on the rescheduled date (Appendix A).

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

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. The collection basket with a 3.2-mm (1/8-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.

2-1

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:

Volume of Total Sample X No. of Fish in Subsample Estimated No. of Fish in Total Sample ~

Volume of Subsample The total volume of the sample was determined by repeatedly filling a 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 1993, 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 LABORATORY PROCESSING (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. All collected 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).

2-2

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 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.

When possible, measurements were recorded with greater accuracy than required (e.g., to the nearest 0.1 gram for specimens between 10 and 2,000 grams) if the scales would allow.

Any unusual conditions, abnormalities, or presence of fish tags were noted on the data sheets.

2.4 WATER QUALITYDE'H<MMINATIONS (PERMIT SECTION IV.B.5)

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

2.5 DATA PRESENTATION (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.
c. Total estimated impingement for each month was calculated using the following formula:

d (x)

C V+

where d = Total estimated impingement c = Number of fish collected during the period v* = Volume of cooling water used during the period

= Based on main circulating water pump(s) operating regime x = Total monthly volume of cooling water used.

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

2-3

d. Additional tables were calculated for mean daily impingement rate (total number of fishes impinged [by species] on all sampling days in a month divided by the total number of sampling days) and a monthly estimated impingement based on rate (mean daily impingement rate multiplied by the total number of days in a particular month) and are available for comparison of data presentation methods and for historical continuity with past data reports.
e. Monthly and annual total biomass (grams) by species and grand totals over all species.
f. Total estimated biomass (adjusted for flow) was calculated in the same manner as estimated impingement.

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

In 1993, the seasonal patterns of fish species diversity and abundance were evident during the course of impingement sampling at NMP Unit 1. Spring impingement abundance (March and April) are slightly diminished due at least in part to a station refueling outage that occurred from 20 February to 17 April. Both main circulating water pumps were usually shut off during the outage, though for brief periods at least one main circulating water pump was operating. During the outage the volume of water was reduced through the intake as a direct result of the shut down of the main circulating water pump(s). The seasonal increase in fish impingement abundance which typically begins in March and April was diminished until the station restarted in mid-April. 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).

Historically, impingement abundance at NMP Unit 1 increases in the spring, corresponding to the migration of alewife and rainbow smelt 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.

The collections of impinged fish at NMP Unit 1 for 1993 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 September and October as a result of storm conditions coinciding with the presence of fish near shore. Samples collected in January and December 199)'also reflect w'inter st'orm conditions and the presence of YOY near shore. The largest fish impingement collections occu'rred in April (22,781), May (30,613), and June (901) .

accounting for 97 percent of the total 1993 fish impingement collections.

Alewife and rainbow smelt continued to dominate annual impingement collections as in most previous years, accounting for 98 percent of the annual fish impingement totals for 1993.

Spottail shiner (231) and trout-perch (199) were third and fourth in abundance (neither are representative important species (RIS). All RIS combined (alewife, rainbow smelt, yellow perch, smallmouth bass, white perch, and lake trout) equaled 54,961 individuals and 98 percent of the annual impingement total. Daily impingement sample results for 1993 are presented in Appendix D.

~ ~ ~

In 1993, fish species diversity occurred in accordance with seasonal abundances and/or behavioral stimuli. Species diversity ranged from a low of 7 species in November to a high

~

of 18 species in December. Low species diversity occurred in March, September, October,

~ ~ ~

~ ~

~

3-1

~

and November. ~ Generally, low diversity results from station outages (March) and periods

~

with little meteorological or behavioral influence on fish populations in the vicinity of

~ ~ ~

NMP Unit 1. The highest diversities resulted in January, April, May, and December with

~

the highest diversity occurring in December (17 species). Species diversities in April and May correlate to inshore movements of many species toward their spawning grounds.

Species variety in January and December 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, February, October, and December).

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 1993, 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 26-27 January resulted in the collection of 54 percent of the monthly impingement total. The sample also contained 66 percent of the month's collection of rainbow smelt. Winds were from the northwest at 15 knots with rough water.

~ In February, an impingement sample collected from 2 to 3 February contained 80 percent of the month's impingement total (with both main circulating water pumps operating). Winds were from the northwest and west 15-25 knots. The sample resulted in the collection of 90 percent of February's collection of rainbow smelt.

~ In October, a 24-hour sample collected from 18 to 19 October during 10- to 20-knot northwest winds and 6-ft waves resulted in the collection of 91 percent of the monthly impingement totals and 99 percent of the October total for alewife. All of the alewife collected were YOY.

~ In December, a sample collected over the 24-hour period of 22-23 December contained 89 percent of the monthly impingement total and 81 percent of the total of rainbow smelt YOY. Winds were northwest at 10-20 knots; waves increased to 5-7 ft. This sample was also comprised of the most species for the year: 17 species plus sculpins.

3-2

Temporal presence or absence of species throughout 1993 followed seasonal behavior and meteorological influence. Alewife and rainbow smelt were collected in 7 and 9 months of the year, respectively. Alewife dominated the impingement collections in 5 of those months.

Rainbow smelt dominated the impingement collections made in January and February; months when alewife were nearly absent from the samples. Smallmouth bass and yellow perch, both RIS, were collected in 9 and 8 months, respectively, and their occurrence is considered relatively common in the collections. White perch, also an RIS, were collected during 6 months of 1993. Lake trout, the only salmonid collected in 1993, were found in samples from 6 'months of the year. Non-RIS found commonly and in relative abundance throughout the seasons of 1993 include stonecat, sculpins, spottail shiner, threespine stickleback, and trout-perch.

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 on 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.

~ ~

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, 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., February and March). 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 will mirror these influences most when both main circulating water pumps are operating (e.g., April impingement rates from 1-18 April and 19-30 April).

The mean daily impingement rate determined by volume (Table 3-3) was highest in April (1,852 fish/MCM), May (1,045 fiish/MCM), and June (154 fish/MCM). These impingement rates are reflective of adult alewife movements to inshore spawning areas. A slight increase in the rate of impingement was seen in October (67 fish /MCM), and December (49 fish/MCM), reflective of the influx of YOY during storm conditions.

The lowest rates of impingement (when at least one main circulating water pump was operating) occurred in August (5 fish/MCM), September (10 fiish/MCM), and November (2 fish/MCM). Weather conditions for the samples were relatively benign with no major storms thereby reducing any meteorological influences on the fish impingement.

3-3

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 the impingement in April and May as the result of inshore spawning movements. Several species, including spottail shiner, threespine stickleback, and white perch also increased in rate of impingement in April and May in response to their species specific spawning behavior. 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 1993: alewife (October), white perch, and yellow perch (December). Non-RIS influenced by winter storms include gizzard shad (January) and pumpkinseed and trout-perch (December). In general, the monthly impingement rates based on flow volume will reflect the collection of fish at times of seasonal abundance and/or under storm conditions seen in Table 3-1.

Calculations of the estimated number of organisms impinged at NMP Unit 1 during 1993 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 115,884 (excluding fragments and crayfish). The estimated annual impingement of alewife was calculated as 105,146 equaling 91 percent of the annual total. The number of rainbow smelt estimated impinged in 1993 was 4,607 (4 percent of the total). The RIS fish estimates were impinged in the following numbers: white perch, 675; yellow perch, 170; smallmouth bass, 285; and lake trout, 62. All RIS fish combined (110,945) comprised 96 percent of the annual estimated fish impingement. For 1993, 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 lake trout. 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 51-75 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 and October).

(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 1993, collections of alewife followed the seasonal length distribution pattern as described (Table 3-6a). Alewife collected from March through July were adult and subadult fish.

From August through December, most alewife collected were YOY. Alewife measured from 3-4

samples collected in 1993 were comprised of 94 percent adults and subadults and 6 percent YOY. The minimum length measured was 4.7 cm (1.9 in.); the maximum length recorded was 18.8 cm (7.5 in.).

Rainbow smelt collections in 1993 (Table 3-6b) were dominated by adults and subadults in April and May. The 1992 year class (yearling) rainbow smelt were collected sporadically throughout 1993 but dominated the impingement collections of rainbow smelt in January and February. Overall, YOY rainbow smelt comprised 26 percent of the smelt measured. The minimum length recorded was 4.6 cm (1.8 in.); the maximum length recorded was 18.5 cm (7.4 in.).

White perch (Table 3-6c) measured from the 1993 impingement samples were predominantly YOY (75 percent). Eighty percent of the YOY measured were collected in December; 89 percent (65 individuals) of those were found in one storm-influenced sample.

Adult white perch were collected as individuals and were collected primarily in April and May. The minimum length measured for white perch was 5.7 cm (2.3 in.); the maximum length recorded was 32.0 cm (12.8 in.).

Yellow perch (Table 3-6d) were collected sporadically throughout 1993. One storm-influenced impingement in April resulted in the collection of 13 yearlings (1992 year class).

The yellow perch measured during impingement collections at NMP Unit 1 were comprised of 84 percent adults/subadults. The minimum length measured was 5.0 cm (2.0 in.); the maximum length was 30.0 cm (12.0 in.) Yellow perch appear to have had a successful spawning in 1992 as evidenced by the increased number of YOY in the impingement samples (EA 1993) and the shift to yearling size in the 1993 collections. Preliminary assessment data on yellow perch captured by U.S. Fish and Wildlife Service trawls during 1992 also indicate a successful 1992 spawning (O'Gorman 1993).

Smallmouth bass (Table 3-6e) collected during 1993 were predominantly adult/subadult (53 percent) and were collected sporadically through the year. The minimum length recorded for smallmouth bass collected in 1993 was 4.3 cm (1.7 in.); the maximum length recorded was 44.6 cm (17.8 in.),

Lake trout, the only salmonid species collected in 1993, were found as adults in samples throughout the year. The minimum length measured was 63.6 cm (25.4 in.); the maximum length measured was 81.5 cm (32.6 in.).

3.3 BIOMASS (PERMIT SECTION IV.B.4)

The total biomass (Table 3-7) collected in the 1993 impingement samples at NMP Unit 1 was 1,621,504 grams, excluding invertebrates and fragments. Alewife accounted for 1,474,592 grams (1,475 kilograms) or 91 percent of the annual total biomass. Alewife and rainbow smelt (10,523 grams; 11 kilograms) combined with the other RIS (white perch, 5,059 grams; yellow perch, 1595 grams; smallmouth bass, 18,526 grams; and lake trout, 25,726 grams) comprised 95 percent of the annual total biomass at NMP Unit 1. Biomass is 3-5

~

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 3,516,558 grams (3,517 kilograms) of which alewife constituted 76 percent (2,670,455 grams; 2,670 kilograms). Alewife, rainbow smelt, and the other RIS collected in 1993 accounted for 85 percent (2,973,614 grams; 2,974) of the annual estimated biomass (excluding fragments).

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

Intake and discharge temperatures recorded along with station generating conditions are listed in Appendix B. From the Appendix B tables, intake temperatures ranged from a minimum of 0.0'C on 12 February to a maximum of 23.4'C on 1 September. The discharge temperatures (when the plant was operating at full power) ranged from a minimum of 18.3'C on 20 January to a maximum of 40.9'C on 15 August 1993. Temperatures discussed above may have occurred on additional days, however, the dates given are the first dates of occurrence for minimum and maximum temperatures in the intake and discharge canals at NMP Unit 1 during 1993.

APPENDIX A EXCEPTIONS TO STANDARD OPERATING PROCEDURES FOR IMPINGEMPlT AT NINE MILE POINT NUCLEAR STATION UNIT 1, 1993 (PERMIT SECTION IV.B.5) 10 MAR Void Impingement Sample. The impingement sample scheduled for collection over the period 10-11 March 1993 could not be collected as planned. A Clam-Trol chemical treatment of the intake for zebra mussel control was in process during the scheduled sample collection period.

The sample was rescheduled and successfully collected over the period 22-23 March 1993.

(NOTE: Normally, Clam-Trol treatments do not interfere with impingement sampling.

However, this treatment occurred during the refuel outage. During this time, the station was isolated from the lake in a recirculation mode for the treatment period with no flow to or from the lake. Impingement sampling was not permitted during this treatment while the station's intake and discharge were in this configuration.)
