ENS 4449115 September 2008 16:39:00

On September 15, 2008 a severe windstorm moved through Oswego County and resulted in local area power outages. Seven (7) of thirty-seven (37) emergency notifications sirens are out of service. Tracking for station reporting criteria of 'four or more sirens out of service for 12 hours or more' was initiated at 02:44 with seven sirens out of service at that time. Five of the original seven out of service sirens remain out and two additional sirens have subsequently lost power. Sirens affected provide coverage to Oswego County. The sirens are utility owned and shared with the James A. FitzPatrick site. In the event the sirens are needed, the County has it's Hype-Reach (911 call back system) on standby. 10 CFR 50.72(b)(3)(xiii) requires reporting within 8 hours when a significant portion of the emergency communication system has been lost. The site emergency procedures defines loss of 4 or more sirens for 12 hours or 19 or more sirens for 1 hour as a significant loss of emergency communications. Since the restoration activities did not result in restoring the siren system to less than 4 sirens out of service by 14:44 this reporting criteria is met. The event has been entered into the corrective action program and the resident inspector has been briefed. There are no other adverse impacts to the station based on this event.
