RE OIL SPILL 7/4/91 - NORTH ANNA POWER STATION

Dear Mr. Kregloe:

An oil spill occurred at North Anna Power Station on July 4, 1991.

This letter confirms our report of the incident to Mr. Sineath at the Department of Emergency Services at 1415 on the 4th.

As Mr. Daniel James discussed with you by telephone on August 22,

-due to changes in personnel and misunderstanding of reporting duties, this follow-up letter regarding the oil spill evant has been delayed.

At approximately 1330 on July 4,-station personnel observed an oil sheen on standing water at the site during on unusually heavy rainfall event. Upon investigation, it was determined that fuel oil from the fuel oil truck unloading area spill basin had been carried into a storm drain, north of the spill basin. Due to the large quantity of water, the oil separator weir at the discharge canal did not contain the oil. Oil soak pads were plLced at the fuel oil truck unloading area spill basin, the storm drain area, the oil separator weir at the discharge canal, the oil boom at the discharge canal and oil booms at the end of the discharge canul.

Oil was noted at the east side of the booms at the end of the discharge canal and was contained by these booms. The total amount of oil spilled was estimated at two gallons. The oil booms and absorbent pads appeared to have been successful in containing and capturing the spilled oil. No evidence of oil contamination was found cutside the discharge canal and no environmental damage was detected.

Although hydraulic overload was the causative factor in this event, the spill nasin is being evaluated to detarmine if any design modifications could help precluda future oil washout. Otherwise, the established procedures and equipment were found to be effective in preventing a discharge to waters outside of the canal.
