Description of Event

On August 8, 1980, an oil sheen was observed on the Conowingo Pond in the area near the berm which separates Conowingo Pond from the C, D,

and E cooling towers.

Consequences of Events:

The amount of oil involved appears to be minimal in that only an oil sheen was visible on Concwingo Pond.

There was no evidence of any droplets or accumulation of oil reaching the river and the environmental impact is considered minimal.

Cause of Event

on the afternoon of August 7, 1980, d rusel oil was delivered to the Peach Bottom site.

This oil was pumped into the

'A' diesel storage tank.

Because the level gauge in the tank was reading an incorrect low value, the tank was overfilled before the level indicator indicated that the tank was full (tank reading was 34,000 gallons when tank was full containing 37,500 gallons).

The

'A' storage tank overflowed to an oil intercepter and then to a waste oil tank with a capacity of 500 gallons.

This waste oil tank also overflowed a slight amount resulting in some oil reaching a drain system.

This drain discharges to an area in the discharge canal which has an oil boom permanently installed.

The overflow was contained within the oil boom.

A minimal amount of oil, however, leaked from the oil boom, mixed with the normal plant circulating water system resulting in the oil sheen extending to the discharge canal.

l

Corrective Action

On August 7, 1980, when the level gauge was noted to be reading incorrectly, the gauge was recalibrated to properly read a full storage tank volume.

At this time, the site was not aware that the storage tank had actually overflowed.

On August 8, 1980, when the oil sheen was observed, immediate steps were taken to remove the oil from within the oil boom and empty the waste accomp'lished by August 8, 1980.
