NORTH ANNA POWER STATION - OIL SPILL 2/26/92
Dear Mr. Kregloe:
An oil spill occurred at North Anna Power Station on February 26, 1992.
This letter confirms our report of the incident to Mr. Sineath at the Department of Emergency dervices at 2030 hours0.0235 days <br />0.564 hours <br />0.00336 weeks <br />7.72415e-4 months <br /> en that date.
At approximately 1915 hours0.0222 days <br />0.532 hours <br />0.00317 weeks <br />7.286575e-4 months <br /> on February 26, ntation parsonnel discovered a diesel fuel oil leak at the fuel pumphouse.
Upon investigation, it was determined that the diesel fuel was coming from the fuel oil transfer system supplying the auxiliary boiler which was - in operation at that time.
A broken fuel oil pump strainer drain had leaked the fuel into the sump.
This equipment 9
f ailure resulted in the discharge of approxiuately 1000 gallons to the ctorm-drain system.
The majority of the lost diesel fuel was contained within the storm drain pipe with an estimated less than 5 gallons discharging into the discharge canal at outfall 004.
The fuel which escaped the storm drain was captured by the oil boom in the canal and removed with absorbents.
None of the fuel reached the Waste Heat Treatment Facility outside the discharge canal. No evidence of environmental damage was found.
Diesel fuel trapped in the storm drain pipe was pumped out into a vacuum tank truck.
The storm drain pipe was. flushed with water to remove as much residual as possible with all fuel being removed at the 004 catch basin.
The fuel / water mixture from the storm drain and catch basin was pumped into drums to be held with the contaminated absorbent materials for proper disposal.

Mr. Wil31am L.
Kregloe March 4, 1992 Page 1 In order to preclude future recurrence of this
- incident, an increased preventive maintenance program
- for, and increased surveillance of, the equipment involved will be implemented.
It is expected that some residual fuel remaining in the storm drain pipe may continue to be fluched out.in small quantities until the pipe is completelf cleansed.
However, the existing practice
>f maintalning absorbents at the 004 basin will ensure capture of any remaining fuel.
Should you desire additional information or have any questions about this matter, plessa contact Daniel Janea at (804) 273-2996.
