Box 236 Hancocks Bridge, New Jersey 08038 Nuclear Department CERTIFIED MAIL JUL 0 2 1993 RETURN RECEIPT REQUESTED ARTICLE NUMBER: P 346 404 623 NLR-E93209 Mr. Steven R. Mathis N. J.

Dear Mr. Mathis:
SALEM GENERATING STATION NJPDES PERMIT NO. NJ0005622 ROOT CAUSE INVESTIGATION CASE NO. 93-05-13-0938-21 On May 13, 1993, Public Service Electric and Gas Company (PSE&G) reported a discharge of oil to the Delaware River from the Salem Generating Station's West Yard Drain, DSN 488. The discharge was reported to both the NJDEPE Hotline (Case No. 93-05-13-0938-21) and the National Response Center (Case No. 173-364). In PSE&G's May 18, 1993 discharge report (NLR-E93154), several sources of the oil were being evaluated as potential causes of the discharge. As a result, PSE&G committed to conduct a root cause investigation of the incident and to provide this report on the investigation results and corrective actions.
PSE&G believes the sheen is due to oil washing from the walls of the collection system piping during precipitation events. The most probable source of oil was identified as either the turbine building roof drains or flood pump. Attached for your review is a summary of the investigation results and recommendations.
In order to correct the deficiencies identified, PSE&G shall perform the following activities:
- 1. Install a 1 inch drain valve on the flood pump discharge piping (Completed June 28).
- 2. Inspect and clean (as necessary) the turbine building roof drains.
130035 The power is in your hands.

- 3. Clean the flood pump discharge line.
- 4. Clarify the wording on the caution Tag located on the turbine building flood pump to specifically require Chemistry Department approval prior to operation.
In addition, PSE&G shall continue the program to inspect and replace oil absorbant boom installed in West Yard Drain manholes as discussed in the May 18 discharge report. Ninety (90) days following completion of the items listed above, PSE&G shall reevaluate the need for the absorbant boom and the inspection program.
If you have any questions or require additional information, Sincerely,
~F~.-
I please contact Pat McCabe of my staff at (609) 339-1245.

Executive Summary Presented here is a Root Cause Investigation of the May 13, 1993 oil sheen discharge from the West Yard Drain outfall DSN 488.
The sheen was approximately 10 ft. by 20 ft. (less than 1 pint of oil is needed to cause this) and was largely contained within the oil containment boom that was in_place between the Service Water and Circulating Water Intake Structures.
The oil sheen is coincident with a heavy rainfall that occurred the previous evening. The actual source of oil is indeterminant; however, it is believed to have come from either the Turbine Building roof drains or the low point of the Flood pump discharge line.
Events & causal Factors May 13, 1993 (times are approximate) 09:30 An oil sheen {approximately 10 ft. by 20 ft.) was observed on the Delaware River in the vicinity of the West Yard Drain, outfall DSN 488.
09:35 The sheen was reported to the Shift Supervisor.
10~00 Representatives from Chemistry, Licensing, Site Services and Technical departments gathered at the scene.
10:45 Walked down the Turbine Building roof drains.
13:00 U.S. Coast Guard arrives and investigates. They photographed the area and took water samples.
May 20, 1993.
09:30 Obtained a sample from the flood pump discharge pipe.
May 21, 1993 14:30 Traced Diesel sump pump discharge line.
Conclusions
- The oil sheen that appeared by the West Yard Drain is coincident with a heavy rainfall that occurred the previous evening. The actual source of oil is indeterminant; however, it is believed to have come from either the Turbine Building roof drains or the low point of the Flood pump discharge line. The following facts support this conclusion:
There have been reported oil leaks on the Turbine Building pedestal.
- Unit 1 Turbine Building roof drains tie into the Flood pump discharge pipe.
A sample of water taken from the Flood pump discharge pipe (on May 20, 1993) contained an oil sheen, a greasy residue and a brownish sediment.
There was a heavy downpour the evening before the oil sheen was detected.
A contractor to Site Services (Video Pipe) inspected and cleaned the yard drains. No evidence of oil was found except in Manhole No. 9 and associated piping.
The Unit 1 Diesel sump pump discharge line is disconnected and 1BD28 (sump pump discharge isolation valve) is Red tagged shut.
Recommendations
- 1. Continue the monitoring program to inspect and replace the oil absorbant boom in the yard drain manholes. Upon completion of the other recommendations, reevaluate need for boom and inspections.
- 2. Install the 1 inch drain valve in the flood pump discharge line.
- 3. Inspect and clean (as necessary) the Turbine Building roof drains.
- 4. Clean the Flood pump discharge line from check valve lBDlO to Manhole No. 9.
- 5. Revise the wording on the Flood pump Caution Tag to convey the potential consequences of operating the Flood pump.
