DISCHARGE CONFIRMATION REPORT - SUPPLEMENTAL INFORMATION RELATED TO DISCHARGE OF LUBRICATING OIL FROM SALEM GENERATING STATION - CASE # 91-11-03-1734-02 MEASURES TAKEN TO CONTAIN, CLEANUP AND REMOVE THE DISCHARGE:

Upon discovery, the leaking valve was tightened, terminating the discharge. Absorbant pads were immediately placed on the floor in the spill area to recover any remaining oil.

The pads were then placed into a 55 gallon drum for disposal as hazardous waste.

CORRECTIVE MEASURES:

The Operations Department, responsible for operation and maintenance of the intake structure and equipment, has placed caps on the drain valves for each of the traveling screen oil baths to prevent future leaks.

INDIVIDUAL INVOLVED IN CONTAINMENT/CLEANUP:

Cleanup activities associated with the release of the lubricating oil, consisting of tightening the drain valve and placing absorbant pads on the floor in the area of the spill, were conducted by Operations personnel. Site Services personnel were responsible for disposal of the used pads as hazardous waste. These individual(s) are:

DISCHARGE CONFIRMATION REPORT - SUPPLEMENTAL INFORMATION RELATED TO DISCHARGE OF LUBRICATING OIL FROM SALEM GENERATING STATION - CASE # 91-11-03-1734-02 TYPE, QUANTITY, LOCATION AND DATE OF SAMPLES:

No samples were collected of this discharge. However, based upon a worst case scenario in which all oil leaked from the drain valve to, the intake bay within one (1) minute, and the oil was dispersed through only one outfall, the estimated concentration of petroleum hydrocarbons in the discharge is 13.5 mg/l. This is below the maximum daily discharge limitation of 15 mg/l imposed by the NJDEPE for similar discharges. Information on this characterization may be obtained from:
