NORTH ANNA POWER STATION - OIL SPILL 5/1/94
Dear Mr. Loyd:
An oil soill occurred at the Lake Anna Dam on May 1,1994. This letter confirms our report of the incident to the Department of Emergency Services at 1030 hours0.0119 days <br />0.286 hours <br />0.0017 weeks <br />3.91915e-4 months <br /> on that date.
At approximately 0920 hours0.0106 days <br />0.256 hours <br />0.00152 weeks <br />3.5006e-4 months <br /> on May 1,1994, a hydraulic oil leak was discovered on the SA hydro unit that is located below the Lake Anna Dam. The unit was immediately shut down and the oil cleaned up from around the leak area. From a measurement of the fluid remaining in the hydraulic oil reservoir, approximately 2 to 3 gallons may have been lost over the previous 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> period. It appears that most of this oil remained on the structure and only a small portion reached the river. The oil was subsequently cleaned off of the structure. A small oil sheen was visible below the hydro unit when the leak was discovered but this dissipated before it could be removed due to the turbulence of the water below the dam.
No evidence of environmental damage, residual ficating oil, or sludges were found during an inspection of the river downstream. The leak wes repaired and the hydro unit was returned to operation on May 2,1994. This event is being evaluated to determine if there are any remedial actions which could prevent a similar leak from entering the river in the future.
Should you desire additional information or have any questions about his matter, please contact Daniel James at (804) 273-2996 Sincerely, Y
