NOTIFICATION TO KENTUCKY ERT DUE TO EXCEEDING PERMIT LIMITS AT OUTFALL
"At 1750, 6/21/2008 CDT, the Kentucky Emergency Response Team (Report Number 2008-2125) was notified of the following issue. The C-637 RCW (Recirculating Water) 'H' Supply loop was being repaired and a residual RCW leak from the valve vault was being pumped back to the pump house basin when the portable pump shutdown causing an overflow condition at a Commonwealth of Kentucky permitted outfall 002. The Commonwealth of Kentucky's permit limit for the outfall is 1 mg/L for total phosphorus and the chlorine level is to be below detectable limits. Contrary to this, the total phosphorus level was slightly above 1 mg/L and residual chlorine was approximately 0.1to 0.3 mg/L. Control of the RCW leak in the valve vault was re-established.
"This event is reportable as 'USEC shall notify NRC of any event or situation, related to the health and safety of the public or on-site personnel, or protection of the environment, for which a news release is planned or notification to other government agencies has been or will be made. Such an event may include an on-site fatality or inadvertent release of radioactively contaminated materials.'
"The NRC Resident Inspector has been notified of this event.
