Ejf 1.0 . Int roduct ion This document is the Oyster Creek Nuclear Generating Station (OCNGS) Annual Environmental Operation Report (AEOR) for 1990. This report is rcquired by Oyster Creek Environmental Technical Specification (OCETS) Section 3.5.l(A).

The OCNGS is a single cycle, forced circulation, bol'.ing water reactor of 620 MWe maximum (summer) dependable not capacity, owned by Jersey Central Power & 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. 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, 1990 through December 31, 1990.

The report is organized in the following format:

Section 1.0 - Introduction Section 2.0 - Environmental Monitoring Section 3.0 - Special Monitorir,g and Study Activities Section 4.0 - Additional Information 2.0 Environmental Monitorine This section is intended to address the results of environ antal monitoring programs required to be implemented by Section 1.1 of the UCETS during the report period. The Fish Kill Monitoring Program was not initiated during this report period.

3.0 special Monitorino and Study Activitiea 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 did not require the perf' , a of any special monitoring or study activities during this report period.

4.0 Additional Information 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 requirementa cf the OCETS.

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

d) Changes to the OCETS 330204491

C330-91-3044 Page 2 4.1 Summary of OCETS Non-Compliances There were no NEORs during this reporting period. As part of this report, however, GPUN is including as Attachment I copies of non-compliance reporte submitted to tt'e New Jersey Department of Environmental Protection during this reporting period for non-compliance with NJPDES Permit No. NJ 0005550.

These permit non-compliances were minor in nature and did not result in an impset~to public health or the environment. l l

Summarv of Chances Made to Federal and State Permite and Certificates which Eprtain to the Recuirements of OCETS On April 19, 1990 the OCNGS received a corrective action NJPDES discharge to ground water permit (NJ 0076147) for the purpose of removing oil contamination in the " Cape Hay" aquifer which had resulted from an underground pipe leak.

A renewal application for the NJPDES DSW permit (NJ 0005550) was submitted l to the New Jersey Department of Environmental Protection on January 31, i 1990. The renewal application also requested the consolidation of the I Forked Rive' ilte DSW permit (NJ 0031097) into permit NJ 0005550. The application was still under review as of December 31, 1990.

Sammarv of Chances in Station Desion Which could Involve and Environmental Imnact l

There were no changes in, or modifications of, station design during the !

reporting period which could involve an environmental impact.

4.2 Eggmary of Chances to the OCETS There were no changes to the OCETS during the reporting period.

Noncompliance with the delta temperature limitation at DSN-002 (Heat Exchanger Cooling Water); Part III, Page 3 of the pertnit.

CAUSE OF NONCOMPLIANCIL Excessive-debris accumulation on the intake pump strainer caused a reduction of cooling water flow which resulted in a temperature increase of the affluent water and corresponding delta temperature.

L DESCRIPTION OF NONCOMPLIANCE DISCHARGE:

The delta temperatura between the intake and discharge of the Heat Exchanger Cooling Water (DSN 002) exceeded the permit limit of 33'F. The temperature difference was measured at 38'F. It is important to note that this effluent stream is brought back into the plant and discharged again through DSN 001, where no violations occurred.

DURATION OF MONCOMPLIANCE:

Duration of noncompliance was approximately one hour.

CORRECTIVE ACTION TO REDUCE NON-COMPLYING DISC M ,

The pump was removed from service and the strainer cleaned. The reserve intake water pump was placed in service.

CORRECTIVE ACTION TO PREVENT RECURRENCE,t Use of two heat exchangers and maximum cooling water flow to minimize the delta temperature. Continued intake pump strainer maintenance.

The OCNGS is a single cycle, forced circulation, boiling water : eactor of ;

, 620 MWe maximum (summer) dependable net capacity, owned by Jersay Central -l l Power & Light ~ Company and operated by GPU Nuclear Corporation. The OCNGS is located in Lacey Township, Ocean County, New Jersey. The plart is subject ,

to Provisional Operating License No. DPR-16.' The date of inittal reactor j criticality was May 3, 1969 and the commercial generation of power began on !

December 23, 1969.

This AEOR covers the period from January 1, 1990 through Deceiber 31, 1990.

4.1 Summary of 'V'ETS Non-Comolianggg l

ihere were no NEORs during this reporting period. As part of this report, however, GPUN is including as Attachment I copierJ of non-compliance reports submittod to the New Jersey Department of Environmenta? Protection during tnis reporting period for non-compliance with NJPDES Permit No. NJ 0005550.

These permit non-compliances were minor in nature and did not result in an impact to public health or the environment.

Summary of Chances Mide to Federal and State Permite and Cert ificates which Pertain to the Recuiremente of OCETS on April 19, 1990 the OcNCS received a corrective action NJPDES discharge to ground water permit (se u076147) for the purpose of removing oil contamination in the 'ats9 May" aquifer which had resulted from an 4 underground pipe lea) .

A renewal application for the NJPDES DSW permit (NJ 0005550) was submitted to the New Jersey Departmeat of Environmental Protection o. Januarj 31, 1990. The renewal application also requested the consolidation of the Forked River Site DSW permit (NJ 0031097) into permit NJ 0005550. The application was still under review an of December 31, 1990.

Summarv of Chances in Station Desion Which could Involve and Environmental Imnact There were no changes in, or modifications of, striion design Curing the reporting period which could involve an environme..;al impact.

4.2 _Summarv of Chances to the OCETS There were no changes to the OCETS during the reporting period.

lEPORT OF NONCOMPLIANCE WITH CONDJTICJS OF NJPDES PERMIT No. NJ 000 5550 REPORT NUMBER 000 5550/90/03.

IDENTIFICATION OF OCCURRENCEt Noncompliance with the delta temperature limitation at DSN-002 (Heat Exchanger Cooling Water); Part III,-Page 3.of the permit.

.o

-CAUSE OF NONCOMPLIANCEt Excessive. debris accumulation on the intake pump strainer caused a reduction of cooling water flow which resulted in a temperature increase of the effluent we.ter and corresponding delta terrporature.

E DESCRIPTION OF NONCOMPLIANCE DISCHARGE:

-The delta temperature between the intake and discharge of the Heat Exchanger Cooling Water (DsN 002) exceeded the permit limit of 33*F. The temperature difference was ;

messured at:38'F. . It is important to note that this effluent stream is brought back -

-into the plant and discharged again through DSN 001, where no violatic a occurred.

DURATION OF NONCOMPLIANCEt Dtwation of noncompliance was approximately one hour.

CORRE;;TIVE ACTION TO RfDUCI NON-COMPLYING DISCHARGE

4. The pump was removed fram service and the strainer cleaned. The reserve intake water

pump was placed in service.

CORRECTIVE ACTION TO PREYEAT RECURRENCE 1 Use of two heat exchangers and maximum cooling water flow to minimize the delta s

temperature. Continued intake pump strainer maintenance.
