1.0 Introduction This document is the Oyster Creek Nuclear Generating Station (OCNGS)

Annual Environmental Operating Report (AEOR) for 1988. This report is required by Oyster Creek Environmental Technical Specification (OCETS)

Section 3.5.1(A).

The OCNGS is a single cycle, forced circulation, boiling water reactor of 620 MNe maximum (summer) dependable net capacity, owned by Jersey Central Power 8 Light Company and operated by GPU Nuclear Corporation.

The OCNGS is located in Lacey Township, Ocean County, New Jersey. The plant is subject to Provisional Operating License No. DPR-16 pursuant to Docket No. 50-219. The date of initial reactor criticality was May 3, 1969 and the commercial generation of power began on December 23, 1969.

This AEOR covers the period from January 1, 1988 through December 31, 1988. The report is organized in the following format:

Section 1.0- ti Intro due on Section 2.0- Environmental Monitoring Section 3.0- Special Monitoring and Study Activities Section 4.0- Additional Information 2.0 Environmental Monitorin This section outlines the environmental monitoring programs to be conducted under Section 1.1 of the OCETS, and provides the status of submission of reports on these various programs. Reporting and notification requirements of events (planned shutdowns and/or fish kills) are specified in Sections 1.1.1 and 3.5.2 of the OCETS and, where applicable, have been met. The results of the monitoring programs are included below in accordance with Section 3.5.1 of the OCETS.

Section 1.1.1 of OCETS specifies the following stu+:

A) Fish Kill Monitoring Program One (1) reportable fish kill occurred during the reporting period (ll/8/88). A'Fish Kill Monitoring Program report covering this event was submitted to the NRC on December 8, 1988. An additional copy of that report is provided as Attachment I.

3.0 S ecial 'Monitoring and Study Activities This section is intended to present the results of any special monitoring and study activities required by Section 2.0 of the OCETS.

Section 2.0 of the OCETS does not require the performance of any special monitoring or stug activities.

4.0 Additional 'nformation This section reports any additional information that is required by Section 3.5.1 of the OCETS which includes a summary of:

a) All OCETS non-compliances (i.e., all NEORs) and the corrective action taken to remedy them.

b) Changes made to State and Federal permits and certificates which pertain to the requirements of the OCETS.

c) Changes in station design which could involve an environmental impact.

d) Changes to the OCETS.

4.1 Summary of OCETS Non-Com liances A Non-routine Environmental Operating Report (NEOR) was filed with the NRC during the reporting period. As mentioned in Section 2.1 of this report, the December 8, 1988 transmittal of information concerning a fish kill event is attached (reference Attachment I).

Included as Attachment II are copies of noncompliance reports submitted to the New Jersey Department of Environmental Protection during this reporting period for noncompliance with NJPDES Permit No. NJ 0005550. These permit noncompliances were minor in nature and did not result in an impact to public health or the environment.

Summary'f Changes Made'to Federal'and'State Permits'and ert> locates"w sc 'rta>n to t e equirements o An application was submitted on February 11, 1988 to the New Jersey Department of Environmental Protection (NJDEP) for the renewal of the Forked River Site (FRS) lfater Diversion Allocation Permit No. 2164P. This application requested authorization to consolidate all existing and proposed wells at both the OCNGS and the FRS (two registered existing wells at OCNGS, two proposed wells for the combustion turbine project at the FRS and three registered existing wells at the FRS), and requested changes in the nature and amount of the existing allocation. This application was still under review as of December 31, 1988.

i On April 21, 1987, a request was made to the NJDEP to delist the FRS Hazardous Waste Generator Identification Number (EPA ID No. NJD980786081). After an inspection of the facility on November 20, 1987, the NJDEP recommended to the Environmental Protection Agency (EPA) that the FRS be removed from the active generator list. On July 20, 1988, the EPA approved the delisting. As of that date, any hazardous waste generated at the site is done so under the OCNGS generator number, EPA ID No. NJD980649172.

On February 19, 1988, a request was made to the NJDEP to amend the FRS NJPDES DSW/DGW Permit No. NJ0031097 to include stormwater runoff from a combustion turbine project at the site. The stormwater runoff would be piped to an oil/water separator before discharge. This request was still under review as of December 31, 1988.

Summary'of-Changes in Station Desi n Which Could Involve an nv>ronmenta m act There were no changes in, or modifications of, station design during the reporting period which could involve an environmental impact.

4.2 Summary'of Chan es"to 'the OCETS There was no change to the OCETS during the reporting period.

n=roduct ion T?:e purpose oi ".his report is <<o document <<he circumstances surrounding he death of approximately 1,429 Cist: .in,the discharge canal of t?:e Oyster Creek Nuclear Genera<<ing Station (OCNGS) on Novem'oer 8, 1988.

The OCNGS had been shut down for refueling and maintenance since September 30, 1988. A large school of Atlantic mennaden (Brevoortia tyrannus) 'had been observed in the condense .discharge since early fal'l. On the morning of November 8, divers oerforming maintenance on the'discharge structure observ d stressed fish near the waters surface, as 'well as dead fish on .t?e bottom, in the vicinity of the condenser discharge. The cause of the fish mortality was r

undetermined. No additional fish mortality has been observed since November 8, Nater iais .and methods If Plant operational data, including Circulating vlater and Dilution Pump status, and intake and discharge water temperature (measured approximately 4 ft. below the surface) data were obtained from the OCNGS Environmental Data og. All of ..he aforementioned oarameters are monitored on a continuous-basis.

Dissolved Oxygen was measured at.- the condenser- discharge and dilution discharge (approximately 3 ft. below t?e surface) using a Yellow Springs instruments dissolved oxygen meter.

Chlorination System operating times and the .results of Total Residual Chlorine (TRC) measurements were obtained from the OCNGS Chemistry Department.

l Ti:e discharge "anal and Oyster Creek, including the residential lagoons, were surveyed oy boat and on foot on November 8. All,dead or stressed f ish obse ved j., >he e areas were collected, ident ified and enumerated . A representative subsample of eac?'. species was measured (fork length) to ti:e nearest cen" imeter.

Trawl sampling and diver surveys were conducted in order to determine the extent to wi:ich dead fish may i:ave accumulated on the bottom. Five bottom trawl samples were collected in Oyster Creek and in two of the residential lagoons (Fig. 1) on November 9. 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 mesi: inner liner.

Diver surveys were conducted along 16 transects, traversing the disci..arge canal perpendicular to the shore, oetween the condenser discharge and t?.e US Route 9 Bridge (Fig. 1) on November 10. Based upon the diver's observation that the majority of ti:e dead fish on the "oottom were concentrated in the area close to ti:e condenser discharge, the diver survey effort was concentrated in that area. Twelve transects were surveyed between the condenser disc?:arge and the old railroad trestle, and four transects were surveyed between the old railroad trestle and the US Route 9 Bridge (Fig. 1). Ti:e diver's field of view was 5 feet on either side of tl:e transect line. All -dead fish along ti..is 10 ft. wide swath were counted and identified. The number of fish per square foot of bottom along each transect was calculated as follows:

At -1045 hours, after being notified of the fisi..kill, ti:e Ci:emistry Department took a second TRC measurement wi.ici: showed, a level of 0, 03 ppm in ti:e condense r disc'na rge, S?:oreline surveys along the banks of ti:e disci:arge canal and Oyster Creek yielded 125 dead or stressed Atlantic menhaden (14.0-27.9 cm FL) and 9 spot (Leiostomus xanthurus; 12.7.-14.6 cm ."-L) .(Table 1).

No dead or stressed fish were found in t}:e 5 bottom trawl samples collected in Oyster Creek and ti:e residential lagoons (Tables 1 and'; ."-'ig.

1). Only live specimens of Atlantic menhaden, spot, winter flounder and several oti:er species were found.

Diver surveys in the discharge canal, between the condenser discharge and ti:e US Route 9 bridge, yielded 96 spot, 49 A" lantic menhaden, 4 winter Eloundes (oseudooleuconectes amecicanusi, and 4 Amesican eel (~An uilla rostrata) (Table 1). The higi..est densi" ies of fish on the bottom were observed in ti:e area between t?e condenser discharge and the old railroad trestle (:"ig. 1). T?e estimate of the total number of dead fish on the bottom, based upon the densities measured. along each diver transect, was 1,295 (Table 1). Adding this figure to ti e 134, fisl: collected in t?.e si:oreline surveys yields an estimated total of 1,429 fish killed during this event.

The cause of ".:".is f'shkill is unknown at ti:is time. The water quality si ow t,.at; no t..e mal shock occurred and that dissolved oxygen ~as not limiting. Chlorine measurements in the condenser disci..arge just orior to and immediately af".,e the first observa" ion of stressed Eisn indicated that TRC levels were ~el.l below the NJPDES oermit l,imit of 0.2 oom and below the lethal concentra" ions reported Eor the eEfected soecies (FpRl 1980) . Interviews of OCVGS Operations personnel indicated tl.at no other chemicals were discharged, The fact that a large school of apparently healthy Atlantic menhaden remained in the condenser discharge after this fishkill indicates that only a oortion of the discharge canal oopulation was effected.

Bruce Halgren and Bill Stansley of the NJDEP were contacted for advice on i:ow the cause of the fishkill might be determined utilizing the frozen tish specimens. They suggested that it would be difficult at best to determine the cause of death based upon cytological examination of the tissues of frozen fish. <Vo Eurther investigation is planned.

Ini ti al Tel ephone Report Date:, Date of yerba]1 Coranunicated to Harr Van Sciver Occurrence: Februar 1 and 17, 1988 on t arc REPORT OF NONCOMPLIANCE WITH CONDITIONS OF NJPDES PERMIT NO. NJ 000 5550 REPORT NUMBER 000 5550/88/01 IDENTIFICATION OF OCCURRENCE:

Noncompliance with Part III, page 3 of the permit. High delta temperature at outfall No. 002 - Heat Exchanger Cooling Water; DESCRIPTION OF NONCOMPLIANCE DISCHARGE,:

The delta temperature (effluent temperature minus intake temperature) at outfall No. 002 exceeded the permit limit of 33.0'F. The temperature difference on February 1, 1988 was 36.3'F and the temperature difference on February 17, 1988 was 41.1'F.

CAUSE OF NONCOMPLIANCE DISCHARGE:

The major cause of both noncompliances is attributed to degraded service water pumps not providing adequate flow to the, system. The design flow for the system is 2000 gal/min. However, the flow for the period of these noncompliances was between 1000 gal/min and 1500 gal/min. This condition was anticipated during the early fall of 1987 which resulted in the ordering of a new pump in October 1987. The new pump was recei'ved on February 19, 988 and 1

was installed and operating by February 26, 1988. The two degraded pumps will be rebuilt with one installed in the system and another placed in storage as a spare.

Another contributing cause of the February 1, 1988 noncompliance was that the measurement was taken duri,ng an upset condition of the Boiler/Evaporator systems.

The measurement taken on February 17, 1988 was obtained when the service water flow was approximately 1'000 gal/min.

Although the maximum delta temperature was exceeded, the maximum discharge temperature of 113'F and the maximum heat load to the receiving body of water were not. In fact, the heat load to the receiving water was only 61% of what it would have been had the design flow rate of 2000 gal/min and the maximum permitted delta temperature of 33'F been achieved.

It should also be noted that .100% of this effluent stream is mixed with water which serves as cooling for the station's main condenser and subsequently discharged again as a part of outfall No. 001 further downstream. Continuous monitoring of the effluent and delta temperature at outfall No. 001 indicated no noncompliances for the reporting period.

DURATION OF NONCOMPLIANCE:

These noncompliances were not identified'ntil the data were collected and analyzed for the preparation of the monthly report. From this analysis it was-determined that both delta temperature calculations for the month were not in compliance. As a result, additional data were analyzed which indicated that the delta temperature w'as not in compliance for other periods during the month as well. However, following the installation of the, new pump on February 26, 1988 the delta temperature remained in. compliance.

CORRECTIVE ACTION TO REDUCE NON-COMPLYING DISCHARGE:

The major corrective active taken was the installat'ion of a 'new service water, pump on February 26, 1988. Additional -actions were taken- immediately upon determining the noncompliance condition to change existing procedures to provide more frequent delta temperature monitoring and recording. Appropriate personnel also were immediately trained on the revised procedure.

CORRECTIVE ACTION TO PREVENT RECURRENCE:

0 The two degraded service water,'pumps, will be rebuilt with one installed in the system and the other placed in'torage as a backup.'ormal lesson plans will .be revised to reference the new procedural changes and all appropriate personnel will be 'giv'en formal'ized cia'ssroom training accordingly.
