ENS 40354 | 25 November 2003 20:10:00 | On November 25, 2003 at 1730, offsite notification was made regarding a 692 pound leak of ethylene glycol from the north cooling tower de-ice system. The de-ice system was shutdown after the event. The National Spill Response Center, EPA Regional Response Center, the Michigan Stale Police Operations Center, State of Michigan Department of Environmental Quality, and US Coast Guard were notified. Site permit requires state notification of any leak above 500 pounds. The material leaked into the cooling pond associated with the cooling tower and the cooling pond water will be slowly decanted into Lake Erie per normal procedure. The cause of the leak is being investigated. There is currently no affect to the plant due to loss of the de-icing system. The Licensee notified the NRC Resident Inspector. |
