sl.0 . INTRODUCTION 4

... ~ This : document is the'. Oyster Creeki -Nuclear Generating Station '.(OCNGS) Annual Environmental Operating Report'(AEOR)_ for 1997. . This report is required by, Oyster Creek Environmental Technical Specification (OCETS) Section 3.5.l(A).

LThe OCNGS is ~a smgle' cycle, forced circulation, boiling water reactor of 620 MWe maximum (summer) dependable net capacity, owned by Jersey' Central Power & Light Company and operated by GPU Nuclear, Inc. The OCNGS is located in Lacey Township, Ocean County, New Jersey. The plant is subject to Operating License No. DPR-16. The date ofinitial reactor criticality was May 3,1969 and the commercial generation of power began on December 23,1969.

This AEOR covers the period from January 1,1997 through December 31,1997. The report is organized in the following format:

,Section 1.0 - Introduction Section 2.0 - Environmental Monitoring Se'c tion 3.0 - Special Monitoring and Study Activities Section 4.0 - Additional Information 2.0 Environmental Monitoring This section is intended to address the results of environmental monitoring required to be implemented by Section 1.1 " Fish Kill Monitoring Program" of the OCETS during the report period. There were no fish kill events at the OCNGS during this report period, 3.0 Special Monitoring and Study' Activities An incident report concerning the capture of an endangered sea turtle entitled " Sea Turtle Incidental Capture Report 97-1", was submitted to the NRC on October 2,1997 (and is provided as Attachment I). This was the first incidental capture of a sea turtle at Oyster Creek since 1994.

- 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-Routine Environmental Operating Reports 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)L ' Changes in station design which could involve an environmental impact.

,4 d)' . Changes to the OCETS.-

' 4.ll Summary of'OCETS Non-Routine Environmental Operating Reports (NEOR)

.There were no NEORs during the report period. Although not required by the OCETS, GPUN included (Attachment II) a copy of a notification of upset / affirmative defense submitted. to the. New Jersey Department' of Environmental Protection during this reporting period for a non-compliance with NJPDES Permit No NJ 0005550. The permit non-compliance was minor in' nature, was the result 'of an upset condition beyond our reasonable control and did not result in an impact to public health or the environment.

During the June 17-18 water sepamtor was disassembled and cleaned and the accessible portions of the pipe, leading from separator to the point of discharge to the emironment. were also cleaned. When the system w fL seal water ibw to the oillwater separator was restored, the resulting discharge water exhibited signs of oil 1- - _ _.__n_____

(

At that point, on the morning of June 19, all discharges from this system to the emironrnent were terminated and the flow from the oil / water separato has been divened into drums since that time.

Dinking that the problem might be the result of oil recidue in the pipe leading from the oil / water separator to the point of discharge, major portions of this pipe were replaced during the June 20-24 period. This activity was observed by Mr. liarry Van Sciver of the NJDEP Central Bureau of Enforcement during an inspection on June 23.

The system was again reassembled and flushed with intake (salt) water but the discharge from the oil / water separat, continued to exhibit signs of oil residue. The system was then flushed with fresh water from our drinking water system, in order to rule out the possibility of any oil residue being introduced from the intake water which flows b3 many marinas and other areas frequented by boats. Despite these effons, the discharge from the oil water separator continued to exhibit signs of oil residue.

On June 26 and 27, the combined seal water flow from the three dilution pumps into the oil / water separator was divided into three separate flows, through clear plastic tubing, so that the quality of the seal water from each pump could be observed prior to entry into the separator. This effon demonstrated that the seal water from dilution pump number three had a milky appearance, while the seal water from pumps one and two was relatively clear. These results indir:ated that the oil in the seal water from pump num5cr 'hree was being emulsified to a point where it could not be removed by the oil / water separator. This was conarmed on the aftemoon of June 27 when dilution pump munber three was turned off and the seal water flow from pump three to the oil / water separator was terminated. As a result of this actim. the discharge from the oi!' water separator exhibited a notable increase in clarity. Two samples of the water Awing out of the oil / water separator on June 28 had petroleum hydrocarbon levels of 12.29 rug /l and 0.92 mg'l; four samples collected on June 29 had levels ranging from <0.5 to 5.94 mg/1. As a precaution, GPUN continues to diven the flow from this system into containers until we are sure that the

/ petroleum hydrocarbon levels will remain in compliance with the permit limitations.

( Re cause of the emulsification of the oil in the seal water from dilution pump number three has been traced to a faulty float switch on the pump that moves the seal water / oil mixture from the dilution pump to the oil / water separator. Apparently, the float switch was activating the pump even when there was an insuflicient amount of mixture to be pumped. This resulted in execssive agitation and emulsification of the mtxture prior to its delivery to the~ oil / water separator. %c shon-term solution to this problem has been to disable the faulty float switch and operate the system manually when necessary. The long-term solution will be to replace the pumps that deliver the {

{

mixture to tie separator with a gravity dmin system, thereby climinating the possibility of a recurnng problem.

' As esidenced by the excellent compliance history of this system described above, GPUN has a record of properly operating and maintaining the dilutmn pump seal water system. Funhermore, GPUN has devoted a significant amount of resources to the tcsolutiori of this problem (e.5,., approximately 400 person hours), including the containerization of the entire discharge flow, cleaning of the oil / water separator, replacement of discharge piping and a major trouble-shooting effon. The emulsincation of the oil in the seal water flow from dilution pump number three is a phenomenon previously not experienced in the approximately twenty-eight years of operating experience at the OCNGS. As such, the event was clearly unintentional and beyond the reasonable control of GPUN. The event was ternporary, the discharge being terminated immediately after GPUN determined that cleaning the oil / water separator and associated discharge piping did not solve the problem.

Accordingly, the temporary exceedances'of the ' daily maximum and monthly. average effluent limitations for -

L petroleum hydrocarbons from DSN 007 reflect an upset condition and support a determination that the exceedances
