Dear Mr. Kregloe:

Re: OIL SPILL AT NORTH ANNA POWER STATION This letter is to confirm our report of an oil spill on Saturday, August 27, 1988. The s Office (Roberts) pill was hours.

at 1122 reported by telephone to the Valley Regional The spill occurred at 0900 hours0.0104 days <br />0.25 hours <br />0.00149 weeks <br />3.4245e-4 months <br />, August 27, 1988 as an operator

' attempted to dewater che oil / water separator. Over the past several weeks the separator has been operating at full capacity due to condensate from the steam cF.ellers entering turbine building sumps. These chillers are only used 'n hot weather. As the operator initiated dewatering some 10-20 gal of oil were carried over, discharging to the discharge caral at Outfall 004. The operator imediately terminated dewatering and began cleanup.

A permanent boom around Outfall 004 was adjusted to contain most of the oil and absorbent pads were used to soak up the oil from the water's surface. No oil escaped the boom permanently deployed at the end of the discharge canal. No oil was deposited on the shoreline and no adverse environmental impact was observed.

Operation of the steam chillers will be curtailed in the near future as the weather cools. This will reduce the volume of water entering the sump system and therefore lessen the risk of a reoccurrence of such a spill. Until then operators will exercise even more caution during the dewatering operation.
