SUMMARY

Fish impingement averaged 0.52 fish / hour during the period January-Jene 1990.

Atlantic,silverside (Menidia menidia),

grubby (M_yoxocephal us aenaem ),

Atlantic-herring (Clupea harenaus harenaus) and winter flounder (Pseudopleuronectes americanus) accounted for 78.0% of the fishes collected.

Ini t 1_ al ' impingement survival for all fishes. from static screen wash collections was approximately 26% and from continuous screen washes 5%.

The collection rate (no./hr.) for all invertebrates captured from January-June

.1990 was '0.58.

Sevenspine _ bay shrimp (Crangon septemspinosa) and longfin

. squid -(Lolico. pealet i' ec:ounted for 60.5% of the invertebrates' impinged.

Mixed species of algae-collected on intake screens amounted to 1,587 pounds.

L The relatively high fish impingement rates from January-June 1989 (0.55) and 3

i 1990 -(0.52),- compared to the'same period in 1988, reflected circulating water pumps _ operating during-these entire periods.

The relatively low invertebrate impingement was not as reflective of increased intake flow, l:

y e

The Pilgrim Nuclear Power Station capacity fcctor was 67% from January -

June _ '1990.

5 Il SECTION 2 INTRODUCTION Pilgrim Nuclear Power Station (lat. 41'56' N,

long. 70'34' H) is located on the northwestern shor.e of Cape Cod Bay (Figure 1) with a licensed capacity of 655 MWe.

The unit has two circulating water pumps with a capacity of i

approximately 345 cfs each and five service water pumps with a combined

-capacity of 23 cfs.

Water is drawn under a skimmer wall, through vertical bar I:

racks spaced approximately 3 inches on center, and finally through vertical travelling. water screens of ' 3/8 inch wire mesh (Figure 2).

There are two travelling' water screens for each circulating water pump, 4

This' document is a. report pursuant to operational environmental _-monitoring and i

reporting requirements of. NPDES Permit No. 0003557 (EPA) and. No. ' 359 (Mass.

DHPC)- for Pilgrim Nuclear Power Station, Unit I.

The report describes impingement of organisms carried onto the ' vertical travelling water screens at Ui11 t I.

It presents analysis of the relationships between impingement, environmental factors, and plant operational variables.

I The report is based on data collected from screen wash samples during January-June 1990.

SECTION 3 METHODS AND MATERIALS lI Three screen washings each week were, performed from January-June 1990 to 7

provide data for evaluating the magnitude of marine biota impingement and 1

associated survival.

The total weekly collection time was 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> (three separate 8-hour periods:

morning, afternoon and night).

Two collections represented dark period sampling and one represented light period sampling, At the beginning of each collectior, pariod, all four travelling screens were i

i washed.

Eight hours later, the screens were again washed (minimum of 30 minutes each) and all organisms collected.

When screens were being washed continuously, one hour collections were made at the end of the regular sampling periods, and 'they represented two light periods and one dark period I;

on a weekly basis.

I Water nozzles directed at the screens washed impinged organisms and debris into a sluiceway that flowed into a trap.

The original trap is made of galvanized screen (3/8-inch mesh). attached to a -removable steel frame and LE W

collected ' impinged biota, in tho' screenhouse, shortly after being washed off the screens. A second trap was designed and used for sampling, in conjunction l

with-. slutceway survival studies,, consisting of a section 'of half 18" j

corrugated. metal pipe with _3/16-inch _ nylon, delta mesh netting attached.

Impinged; blota sampled ' by this trap were collected' at the end of a. 300' I

,g i 5' sluiceway where initial, one-hour and latent (56-hour) fish survival were

~' determined for static (8-hour) and continuous screenwash cycles.

LI

=_

I' Variables recorded for organisms were total numbers, and individual total lengths -(mm) and weights (gms) for up to 20 specimens of each species.

A l

random sample of. 20 fish or invertebrates was taken whenever the total number for a species exceeded 20; if the total collection for a species was less than

'20, all. were measured and weighed.

Field work was conducted by Marine Research, Inc.

I Intake seawater temperature, power level output, tidal stage, number of circulating water pumps in operation, time of day and date were recorded at time of collections.

The collection rate (#/ hour) was calculated as number of-organisms' impinged per collecting period divided by the total number of hours

.in that collecting period.

All common and scientific names in this report follow the American Fisheries Society (1980) and Smith (1964).

meu RESULTS AND DISCUSSION I-4.1 fis.hn In'441 collection. hours, 231 fishes of twenty species (Table 1) were_ collected from Pilgrim Huclear Power Station intake screens during January-June 1990.

.The collection rate was 0.52 fish / hour.

Atlantic silverside (Henidia menidia) was the most abundant species accounting for 55.8% of all fishes collected (Table 2).

Hinter flounder (Pseudooleuronectes americanus), Atlantic herring.

(Clup.e_4 hAr_engM.1 harenaus) and grubby. (Hvoxoce.phahti Aflutens) accounted for 8.2, 7.8 and 6.1% of the total number of fishes collected.

Atlantic silverside_ were impinged in highest numbers during February and March.

These were primarily adult _ fish that averaged 102 mm total length.

Hinter flounder were mostly impinged - in January, Atlantic herring in May and grubby during January.

The January-June-1990' fish impingement rate was comparable to the

. same period in 1989 (0.55).

This increase for the past two years from the 1988 rate (0.30) is possibly attributable to greater circulating water pump

~

operating capacity in 1989 and 1990.

4.2-Invertebrates In 441 collection hours, 256 invertebrates of 16' species (Table 3) were collected from Pilgrim Station intake -screens between January-June 1990.

The collection rate was 0.58 invertebrates / hour.

Sevenspine bay shrimp (Crangon igpiemsplDRIA) and longfin squid (Lojigo - nealeli), - accounted for 50.0 and 10.5%, respectively, of the total number of invertebrates collected.

The collections of sevenspine bay shrimp occurred primarily in January, and longfin squid during June.

In 1989 from January - June, blue mussels and

= mussel predator s_ dominated possibly due to the lack of effective macrofouling I

controls then.

Sixteen specimens of the commercial;y important American

- lobster.(Homarus americanus) were captured which is high compared with previous years.

I Approximately 1,587 pounds of mixed algae species were recorded during impingement samaling, or 3.6 pounds / hour.

Like the January-June 1989 and 1990 fish impingeme it rates, the algal impingement rate for these years was notably higher than recorded for-the same period in 1988.

Ei 4.3 -Fish' Survival Fish survival data collected while impingement monitoring was conducted are shown 'in Table 4.

Static screen wash collections provided much higher numbers of ) fishes and; revealed' higher initial. impingement survival rates for most species.- Continuous. screen wash collections had low initial survival rates, although'.so few fishes were sampled that this is not a good indicator of, continuous wash survival. ' After 1-hour and 56-hour holding periods data were a limited because of ~ survival pump - freezing problems --in the winter, or fishes b'elng lost, or collected in the screenhouse where no survival facilities are-located.

SECTION 5 CONCLUSIONS I

1.

The average Pilgrim collection rate for the period January-June 1990 was 0.52 fish / hour. ' The collection rate was comparatively lower in 1988, than in 1989 and 1990, possibly due to more circulating water pump capacity during the latter years.

2.

T'wenty species of fish were recorded in 441 impingement collection hours.

3.

The major species collected and their relative percentages of the total collections were Atlantic silverside, 55.8%; winter flounder, 8.2%;

Atlantic herring,-7.8%; and grubby, 6.1%.

g 4.

The hourly collection rate for' invertebrates was 0.58 with severspine_ bay shrimp 50.0% and longfin squid 10.5% of the catch.

Sixteen American lobsters were, caught.

Impingement rates for invertebrates were higher and algae lower for this period in 1988 than in 1989 and 1990.

I 5.

Initial impinged fish survival was' relatively high for species 'during static screen washes, compared to continuous washes.

lW II.

Pilarim Station-1989/90 oDerational review I-

. Bob' Anderson reviewed recent Pilgrim operational. history, beginning with Nuclear Regulatory Commission permission.to resume i:

power generation in December 1988.

By March 1989, Pilgrim was at

,'m 25% power, -increased to 50% by' August, and: attained 100% for a

,E~

briar Pariod in mid-ootober befora und r90ing a planned one month outage.

Since then, the plant has run at near 100% capacity for majority. of time.

The '1989 year can thus-be viewed as the I.

transitional in regards to operational status.

Boston Edison (BEco) anticipatos high operational years for Pilgrim in 1990/1991.

1

.I;

1 L

Jim Blake inquired regarding the number of circulating sea water

-(CSW) pumps operating during 1989.

Bob explained that if a CSW j

pump is on for more than 15 days in a particular month, it is a:

. considered operational for the month in env4.ronmental analysis, g

[

Bob mentioned that BECo will not likely consider increasing j

E Pilgrim's maximum power generating capacity by 10% (60-70 MW ) in l

the near future. There is no definitive timetable for this requ,est.

With an allowed T of 32 F above an ambient 7 0*F Intake temperature, Pilgrim has a maximum allowable discharge temperature by EPA permit of-102'F.

In reality, dischargo temperatures g

typically do not exceed the mid-90s in the warmer months.

With a g

10% increase in power generation, more cooling water would be needed with some concomitant change in the thermal plume to maintain current temperat.ure limits.

III. Imoincement/overflicht monitorina results for 1989 l

Impingement sampling at the intake embayment followed the same schedule of previous years.

In 1989, the first year since early 1986 of relatively consistent two pump operation, the impingement-g rateL was 0.8 fish / hour for an extrapolated annual total of

'g' approximately 7,000 fish impinged.

T1.is was lower than the l impingement average for 1973-89 of 17,000 fish / year. The rates for 1987 and 1988 were very low due to shutdown at times of both CSW pumps.

In' 1990/1991, with both CSW pumps in operation, impingement rates should increase.

In the report, it'is the initial survival Lof-impinged-fish that ' is stated.

Latent survival (56 hours6.481481e-4 days <br />0.0156 hours <br />9.259259e-5 weeks <br />2.1308e-5 months <br />)

~g

. studies of impinged fish in the holding pool have not been possible 5

for some time; - Mike = Scherer explained' that pump maintenance-problems have curtailed the water supply to the holding pool, g

After some discussion, the Committee asked Ted Landry of EPA to g

officially inquire. of BECo as to the repair status of intake'. sample -

pumps located by the intake wall and to express concern that latent impingement mortality presently cannot be measured.

BEco should be allowed one month to rectify these pump deficiencies.

Don _ asked if the Fisheries subcommittee has investigated the sampling design of the. impingement study to see whether the right-j' questions are being asked, since Pilgrim may increase its capacity E

by;10% inlthe.near future.

Carolyn noted that with Mike now on that ? subcommittee, they. Will look closer at entrainment:.and a

impingement.

g Bob Anderson mentioned that the overflight pilot sighted three large fish schools within one mile of-Pilgrim Station in 1989,'but regulators were not notified as the plant was operating at lesa than 50% thermal-capacity at those times, hence th? fish were at

. minimal _ risk-to gas bubble disease.

IV.

Marine Fisheries Monitorina Results for 1989

. Bob ' Lawton stated that DMF is. considering' changing to a a

species _ approach in reporting its study results and would

-g appreciate comments from the Fisheries subcommittee at their I

Il a

g

^

meeting in July.

Brian Kelly noted that the DMF commercial lobster monitoring near PNPS showed a slight increase in the area-wide legal catch rate (CTH - ~ catch per trap haul).

The CTH increased in both the J

reference (36%) and impact (20%) quadrats.

Brian mentioned that 1989 was the fourth year of the research

'I lobster study,-and that the legal catch rate (CTHSOD - catch per trap haul. per - set-over day), weighted by soak time, increased slightly.

The long-term outage (1986-1988) at Pilgrim provided a

-g-three year baseline period of no heat but some current, while 1989

-g_

was a transitional year relative to thermal output.

Data analyses follow a design suggested by Thomas and van Voris (1978) for impact studies of a single site - (treatment) compared with two control sites.

The baseline period was used to establish the relationship.

(ratio) of the CTHSOD in-the impact site versus the average of the two control sites.

Size frequency differences of legal lobster I

will be compared between sites.

With this study,'DMF can control several variables (bait type and trap design, trap soak-time, and trap placement) which often confound data interpretation from studies of actual commercial lobsterman catches.

Vin Malkoski: talked about DMF's cunner tagging initiative.

Gillnet catches of cunner at the Pilgrim discharge area have-declined since 1981.

Cunner populations are typically. Very

.E

discrete, and hence may ' be especially susceptible to-local B'

environmental-perturbations (overfishing or thermal impact).

DMF is considering investigating the cunner in the discharge area in g

more detail.

Potential cunner attraction to the discharge current gl

.is one facet that could be explored via tagging.

Vin presented slides of DMF's preliminary cunner tagging operation.

Bob Lawton mentioned that'the DMF final report on the Jones

~I~

River Smelt Study is-complete-and the comments of reviewers have been incorporated.

Bob presented a-slide show highlighting the smelt' sampling activities-involved, and briefly described the j:

evolution of1-the study.. Smelt eggs, larvae, and adults were each 3'

focused upon in the study.

Marine Fish and Benthic Subcommittees.

Membershio and Schedules for 1990 Regarding -the Fisheries -subcommittee, Ted Landry suggested filling the EPA slot vacated by Mike Bilger with John Paar of the-B

' Lexington laboratory.

Ted will send a letter to-Chairman Szal.

notifying him that Paar will serve on the Committee.

Fisheries subcommittee chairperson, Jack Finn, Will contact Paar once Chairman Szal receives Ted's letter.

Bob Maietta will talk with

Steve Halterman to determine which one of them will be the' DWPC -

representative. Fisheries subcommittee membership follows: 1. Jack Finn, Chairman, U Mass;

Don Miller sees no problem with DMF being~on the subcommittee if the membership is ' full' and it.has I

fisheries expertise, which it will have with the addition of Paar

~and Higgins.

Don cautioned about expanding the subcommittees as it intrinsically creates more. work for those

involved, and he recommended that the subcommittees invite the necessary contractors-to. meetings'rather than formalizing the contractors as committee l

members.

The Fisheries subcommittee will meet at 10 AM on 5

- Wednesday, July 18 at Pilgrim's I&S building.

The Benthic subcommittee needs a regulatory EPA representative 3.

with benthic experience; Chairman Miller is from the non-regulatory g;,

EPA Narragansett Lab.

Ted Landry will talk to Lexington's Peter

. Nolan concerning a qualified candidate who can make the time

. commitment to serve on the subcommittee.

Judith Pederson will

- replace Nancy Maciolek as the Coastal Zone Management representative.

The Benthic subcommittee will meet at 10 AM on Tuesday, July 31 at the EPA Narragansett Lab.

Bob Anderson g'

reminded Committee members that he needs to submit budget requests W

by the first week of August in order to begin next year's monetary planning.

Benthic Monitorina Results - 1989 Jim Blake described. the extent of the Chond rus delineated denuded-stunted-normal, zones off the plant discharge 'in 1989.

J

' These zones have been defined for years on the observations of

Jim briefly reviewed Battelle's 1989 g

Pilgrim report, stating that future data analyses by.SAIC should concentrate. more ~ on long-term trends of-dominant species (e.g.,

' blue mussel) than on species diversity, measures.

SAIC will i

contract out one-half of its Pilgrim taxonomic work.

Don : mentioned ~

Battelle's claim of being underfunded to, do-the annual' Pilgrim L

VIII. Entrainment Monitorino Results - 1989 It

- remained ~ the same as in previous years.

Forty species were Mike Scherer explained that MRI's entrainment sampling scheme entrained in 1989.

Data highlights included the paucity of cod eggs from January through March for the second year in a row, the

'B-abundance of fourbeard rockling, hake and mackerel eggs in May and June, and the low number of larval winter flounder observed in May.

a-Data from 1989 follow the previously noted pattern of egg'

'g' entrainment being relatively independent of circulating ceawater pump operation.

Entrained eggs are assumed to have zero survival; previous limited studies demonstrated a 45% survival for entrained labrid eggs, however.
