1 Introduction -

(a The purpose of this report is to document the ciecumstances, surrounding the death of several thousand: Atlantic menhaden (Brevoortia tyrannus) in:the discharge canal of the Oyster Creek Nuclear Generating Station (OCNGS) during the period July 14-28, 1987 The OCNGS had been operating at nearly full' power, within' the temperature limits of its NJPDES Discharge Permit, since mid-May, 1987. A large school of Atlantic menhaden was obse rved in the condenser discharge throughout .the spring. Sometime during the summer these fish moved f rom.the condenser discharge area into the dilution pump discharge, piesunably to avoid.the relatively high water temperature in the former area. From July 14 through July 28, eight separate instances of fish mortality were observed-in the e

discharge canal. On the morning of July 30, the OCNGS shut down and no further fish mortality has been observed as of this stiting.

Materials and Methods -

The discharge canal of the OCNGS is inspected on a routine basis'by plant security personnel who are instructed to notify the Group Shift Supervisor I l

1 (GSS) if any dead or stressed fish are observed. When the GSS is notified of such an occurrence, he alerts the Environmental Controls Department from which Environmental Scientists are dispatched to investigate the situation. The Environmental Scientists measure intake and discharge water temperatures, I

other water quality parameters as necessary, and determine the number of dead or stressed fish. If the number of fish involved is equal to or greater than l

lu:), as was the case on July 14 and July 28, the incident is considered a reportable'fishkill according to the U.S. , Nuclear Regulatory Commission's Appendix B Environmental Technical Specifications'. In such instances, the investigation continues and includes the following:

1) Notification of the USNRC and the NJDEP.

2) Continuous water temperature monitoring at the condenser intake and discharge and the U.S. Route 9 Bridge.- Temperatures are measured 4 ft. below the surface. Subsequent to four of the eight instances of fish mortality, dissolved oxygen was;also measured at the condenser discharge and dilution discharge (3-5 ft. below the surface) using a Yello 4 Springs Instruments dissolved oxygen meter.

3) Collection of fish - The discharge canal and Oyster Creek, including the residential lagoons, were surveyed by boat and on foot. All dead

,or severely stressed fish were collected, identified, and enumerated. ~ The actual number of fish counted was corrected by a-factor of 25% to account for individuals lost to predators (crabs, fish and birds) and those picked up by local residents. The lengths I

(fork length) of a representative sample of fish were ' measured to the nearest millimeter. All fish were stored in plastic bags and held for at least 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> pending i.ispection by NJDEP personnel.

4) Disposition of dead fish - Whenever possible, an attempt is made to find a beneficial use for these fish. Due to the high air and water tamperatures during these fish kills, decomposition occurred at a rapid rate. As a result, except for several dozen individuals given to local residents for crab bait, all of the fish were buried on the

]

farm property across from the OCNGS.

l

, .~

5) If it is suspected that a.significant number cf fish sank to the bottom, trawl samples .are collected in the discharge canal and the residential lagoons. Subsequent to the fishkill'of July 14, bottom trawl' samples were collected at three locations in Oyster. Creek and in two of the residential lagoons (Fig. 1). Trawl samples were collected using a 4.9 m semiballoon otter trawl with a 3.8 cm nylon stretch mesh body and a 3.2 cm stretch mesh codend, fitted with a 1.3 cm stretch mesh inner liner.

Results and Discussion -

Approximately 5,071 fish were killed in eight separate incidents.(Table 1). Only two of the incidents involved 100 or more dead fish (7/14 and 7/28) and the Atlantic menhaden was the only species involved.

During the evening of July 14, approximately 2,978 Atlantic menhaden were killed. Prior to this event, condenser intake (ambient) temperature ranged from 85.3 to 89.l'F. The condenser discharge temperature ranged f rom 104.8 to 105.8 and the condense r delta T ranged f rom 16,4 to 19.5'F during the same period (Fig. 2). The average length of these fish was 22.9 cm (range =

19.7-30.5 cm) and they were observed floating in the condenser discharge area l

and along the discharge canal as far downstream as the residential lagoons.. -l Approximately 10-15% of the dead fish showed signs of attack by predators (clean bites taken out of the caudal fin and ventral portion of the body). At the same time as the dead fish were observed, a large school of apparently healthy menhaden remained in the dilution pump discharge area (Fig. 3). All of the dead menhaden were found floating except for a 'small number pulled down i

2

F. . ..

by crabs near the shoreline. No menhaden (dead or alive) were taken in the trawl samples collected the following day ,(7/15) .

_ Six smaller fishkills (18-75 fish) occurred during the July 19-25 period when ambient water temperatures were among the highest recorded during the past ten years (in excess of-91*F). Condenser discharge temperatures approached the maximum level (106'F) allowed by the NJPDES permit and condenser delta T's during these events ranged f rom 14.1 to 20.8'F (Table 1) .

All of these incidents occurred betweer. 2100 and 2330 hours0.027 days <br />0.647 hours <br />0.00385 weeks <br />8.86565e-4 months <br />.

Qualitative observations by Environmental Scientists during this period indicated a large amount of feeding activity by predatory fishes in_the dilution pump discharge area where the Atlantic menhaden were concentrated (Fig. 3). Hook and line sampling yielded bluefish (Po;natomus saltatrix; approx. 45 cm) and weakfish (Cynoscion regalis; approx. 40 cm). Large schools of Atlantic needlefish (Strongylura marina; approx. 15-40 cm) were also observed. Predatory activity seemed to increase at about 2000 hour0.0231 days <br />0.556 hours <br />0.00331 weeks <br />7.61e-4 months <br />s-and continued at a high level until about 2330 hours0.027 days <br />0.647 hours <br />0.00385 weeks <br />8.86565e-4 months <br />. It was also apparent that the school of menhaden partially dispersed after dark. Portions of the school sete found much further downstream in the dilution pump discharge at night, I 3

whereas they were densely concentrated in the upstream portion of the dilution discharge during the day. Dead menhaden first appeared in the area between the condenser and dilution pump discharges (Fig. 3) at about 2100 hours0.0243 days <br />0.583 hours <br />0.00347 weeks <br />7.9905e-4 months <br /> and continued to appear until about 0100 hours0.00116 days <br />0.0278 hours <br />1.653439e-4 weeks <br />3.805e-5 months <br />. Throughout this period a large number of apparently healthy menhaden was observed in the dilution pump discharge.

On July 28, 1987, approximately 1,855 Atlantic menhaden were killed under circumstances similar to those described above. Intake temperature at the v-time the fishkill began (2245 hrs) was 84.l'F, condenser discharge temperature was 104.~2*F and the delta T was 20.l'F (Ta,ble 1; Fig. 4). The dead fish ranged in length f rom 20.0 to 30.8 cm, the average length being 22.9 cm.

Roughly 10% of these fish showed signs of predation as described above.

Four ' circulating water pumps and two dilution pumps were operated without interruption and the maximum condenser discharge temperature and delta T were ms.intained within NJPDES permit limitations.throughout'the July 14-28' period.

Dissolved oxygen concentrations in the condenser discharge were at 70-80%

saturation and were very similar to those in the dilution pump discharge, where a large school of menhaden remained during the fishkills, suggesting that dissolved oxygen was not a limiting factor (Table 1).

The fish mortalities described above can be attributed to thermal shock resulting f rom the movement of menhaden f rom the dilution pump discharge, 4here ambient temperatures were extant, to the condenser discharge area, where water temperatures were 14-21'F nigher. Heat shock studies on Atlantic menhaden have shown that mortalities of greater than 50% can oe. expected when fish acclimated to 77-81*F are exposed to experimental temperatures above 91.4'P or delta T's greater than 18'F (Jersey Central Power and Light Company, 1978). In two experiments where menhaden were acclimated to 81*F, 1004 mortality was observed within 3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> of exposure to a delta T of 13'F and within 12 minutes of exposure to a delta T of 18'F (Jersey Central Power and Light Company, 1978). The menhaden concentrated in the dilution pump l

discharge during July 1987 were acclimated to ambient temperatures ranging from 82 to 91*F. The experimental data suggest that the high end of this  !

l range of ambient temperatures may have been stressful for the fish. Movement into the condenser discharge area resulted in substantial additional stress I

j l

l

~

associated with exposure to temperatures as high as 105.8'F and delta T's as high as 20.8'F (Table 1; Figs. 2, 4). ,

Circumstantial evidence suggests that the menhaden were forced by predatory fishes to move into an area characterized by water temperatures they -

would normally avoid. The increase in predatory activity 'af ter dark, concurrent with the daily maximum delta T's-(Figs. 2, 4) and the dispersal of the school of menhaden, resulted in a situation where these fish were highly susceptible to thermal shock. It is reasonable to assume that portions of the school of menhaden were chased out of the dilution pump discharge area by predators each night, thereby being exposed to extremely stressful increases in water temperature. The consistent timing of these events, the presence of predatory fish in the canal, the bite marks observed on dead fish, and the ,

variable numbers of fishes killed each night, all seem to corroborate this explanation.

When the OCNGS shut down on July 30, several thousand Atlantic menhaden remained in the dilution pump discharge. The two operating dilution pumps were turned off af ter the discharge canal water temperature had f allen to-ambient levels in an attempt to reduce the attractiveness of this area to i

i these fish. When the station was restarted on August 5, the dilution pumps were not turned on until the water temperature at the US Route 9 bridge -l approached 87'F (as required by the NJPDES permit), thereby eliminating the ambient temparature ref uge af forded by the dilution flow. It is hoped that these actions have induced the Atlantic menhaden remaining in the' discharge canal to move out of the canal and into the bay, precluding any additional thermal shock mortalities. 1

Noncompliance with item 9b(6)b, page 6 of the permit.

CAUSE OF NONCOMPLIANCE:

The discharge-intake temperature difference of the cooling water of Augmented Offgas - New Radwaste System exceeded the permit limit of 27*F. The temperature dif ference was 33*F.

DESCRIPTION OF NONCOMPLYING OISCHARGE:

There was an overload of heat in the New Radwaste System which caused the noncompliance. The one heat exchanger and one evaporator in service at the time were unable to accommodate the excessive heat load.

DURATION OF NONCOMPLIANCE:

Unknown. i CORRECTIVE ACTION TO REQUCE NON-COMPLYING OISCHARGE:

No corrective action taken because the noncompliance was not identified until the data were collected and analyzed.

CORRECTIVE ACTION TO PREVENT RECURRENCE:

1 Temperature data for previous months was reviewed which indicated that the system was in compliance with the permit. It is believed that this was an isolated incident. Additionally, one Radwaste System service water pump is out of service for repair. Once it is returned to operation the pump can be used to prov'de additional flow to the Radwaste System to aid in mitigating future events, if one should occur.

CAUSE OF NONCOMPLIANCE:

!ntake screen number 5 has been taken out of service and port 5 has been closed, causing the intake velocity to be exceeded. 1 DESCRIPTION OF NONCOMPLYING DISCHARGE:

With only five screens and five ports in service at the intake structure, the i

condenser cooling water flow is obtained through a smaller area, thereby increasing the intake velocity over the normal operating regime of six screens-six ports.

The average intake velocity for at ports 3, 4, and 6, was 1.15, 1.14 and 1.28 respectively.

DURATION OF NONCOMPLIANCE:
