1.0 Introducticn This document.is the Oyster Creek Nuclear Generating Station (0CNGS)

Annual Environmental Operating Report (AEOR) for 1984. It is submitted in accordance with Section 4.5.1 of the Oyster Creek Environmental Technical Specifications (OCETS).

~0CNGS is a single cycle, forced circulation, boiling water reactor of 620 MWe maximum (summer) dependable net capability, 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 a 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, 1984 through December 31, 1984. The report is organized such that Sections 2.0 and 3.0 correspond to those same sections in OCETS. However, due to differences in the required reporting dates of various studies conducted in accordance with OCETS, reports of those studies.have been or will be submitted under separate cover and will not be duplicated in this report. In each of these instances, a confirmation of the filing of the required reports is provided in the appropriate sections of the AEOR. All data which are otherwise required to be presented in the AEOR are included in this report.

2.0 ~ Environmental Monitoring This Section of the AEOR outlines the various environmental monitoring programs to be-conducted under'Section 2.0 of the OCETS, and provides the status of submission of reports on these various programs. The reporting requirements of the studies required in Section 2.0 do not coincide with the required due date of the AEOR.

Meterological data are contained in the Semi-Annual Effluent Release Reports which were submitted on August 31, 1984 covering the first six (6) calendar months of 1984 and on March 1, 1985 covering the.lcst six (6) calendar months of 1984. These data are therefore incorporated by reference into this AE0R.

2.1 Biotic - Aquatic Section 2.1.1 of OCETS specifies the following studies:

a)- Impingement of Organisms

1. Conventional Travelling Screens

2. Fish Return System b) Fish Kill Monitoring Program The OCETS requires these studies be submitted annually in February of each year. However, since the plant did not operate during the reporting year for these studies (September 1,1983 through August 31,1984), they were not performed.

- 3.0 Special Monitoring and Study Activities This Section of the AE0R presents the results of the two special

+

monitoring and study activities required by the OCETS.

3.l' Woodborer Monitoring Program This program has reporting requirements which are different from the other OCETS programs. During the reporting periods the following submittals were made.-

a) The 35th Quarter Report covering the period from October 21, 1983 to January 31, 1984 was submitted on February 29, 1984.

b) The 36th Quarter Report covering the period from February 1, 1984 to April 30, 1984 was submitted on May 31, 1984.

c) .The 37th Quarter Report covering the period from May 1, 1984 to July 31, 1984 was submitted on August 31, 1984.-

d) The 38th Quarter Report covering the period from August 1, 1984 to October 31, 1984 was submitted on November 30, 1984.

-In addition, as per OCETS, the annual report for.the program will 1

be submitted by the-end of May.1985. Therefore, no results of '

this program are presented herein.

3.2 Unusual or Important Environmental Events There were no occurrences of unusual or important' environmental events during this reporting period.,

l 4.0 Additional Information This Section of the AEOR reports any additional information that is I required by Section 4.5.1 of the OCETS:

a) All OCETS non-compliances and the corrective action taken to remedy them.

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

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

d) Changes to OCETS.

4.1 Summary of OCETS Non-Compliances There were no Nonroutine Environmental Operating Reports filed with the NRC during this reporting period.

However, the following NJPDES noncompliance reports were submitted to the New Jersey Department of Environmental Protection as required by the provisions of NJPDES permit No. 000 5550. For additional detail, please see the noncompliance reports which have been previously submitted to the NRC:

1. On January 23, 1984, the discharge / intake temperature difference of the cooling water for the Augmer.ced Offgas--New Radwaste System was 33 F and exceeded the pennit limit of 27*F for approximately seven hours. GPUN believes that the present limit is inappropriate because of equipment operating constraints and unnecessarily stringent because of lack of environmental effects. Therefore, GPUN has requested the New Jersey Department of Environmental Protection to increase the allowable temperature difference for this discharge to 33*F so that the affected equipment can om oparated efficiently without causing permit violations.

2. On April 17, 1984, the discharge /'atake temperature difference of cooling water for 6he Augmented Offgas--New Radwaste System was 32.6*F and exceeded the permit limit of 27 F for an undertermined period of time. As stated in number 1 above, GPUN believes that the present limit is i appropriate because of equipment operating constraints and unnecessarily stringent because of lack of environmental effects. Therefore, GPUN has requested the New Jersey Department of Environmental Protection to increase the allowable temperature difference for this discharge to 33 F so that the affected equipment can be operated efficiently with out causing permit violations.

3. On August 20, 1984 an improperly set chlorine cycle control switch may have caused the discharge of chlorine from the B South Condenser Section for more than the two hours allowed I

by the permit. Upon discovery, station personnel reset the control switch to the proper mode.

4. During the period from September 15 through Septerber 30, 1984, four circulating cater pumps were operated however the intake water velocity measurements were not taken as required by the permit. Although the missed measurements were a noncompliance, estimates of the water velocity were made l based on the operating conditions at that time and the regulatory approved velocity prediction chart. Those estimates indicated that the actual intake water velocity limits were not exceeded.

5. On December 6, 1984, low seal and lube cooling water pressure in the 1-1 dilution pump caused it to trip off line for 23 minutes leaving only one dilution pump (pump 1-2) in service for eight minutes longer than the 15 minutes allowed by the permit.

6. On December 19, 1984, low seal and lube cooling water pressure in the 1-2 and 1-3 dilution pumps caused them to trip off line for 20 minutes which was five minutes more than the 15 minute's allowed by the permit.

4.2 Summary of Changes Made to Federal and State Permits Which Pertain to the Requirements of OCETS There were no changes to Federal or State permits which impacted on OCETS during the reporting period.

4.3 Summary of Changes in Station Design Which Could Involve an Environmental Impact a) The new fish trough used for the removal of impinged organisms and screen wash water from the intake traveling screens was completed and placed into service during November, 1984. The new trough will reduce the mortality rate of impinged organisms because its design reduces the velocity of the wash water and contains other features which reduce the potential for damage to organisms transported by the trough.

b) The new fish sampling pool was also completed and placed into service during November, 1984. The sampling pool allows for more accurate interpretation of the data used in our Section 316 Demonstration and will also significantly improve our ability to assess the impact of plant operations on nearby fisheries.

4.4 Summary of Changes to OCETS There were no changes to the OCETS during this reportir.g period.
