On December 04, 2007 at approximately 07:00 Mountain Standard Time (MST), the Palo Verde Emergency Preparedness Department discovered sirens 17, 18 and 23 out of service. Siren #23 was restored to service at 09:34 and siren 18 was restored to service at 10:32. Siren 17 remains out of service and is estimated to impact approximately 206 members of population in the emergency planning zone (EPZ) within 5 miles. Palo Verde's reporting criterion is a loss of capability to inform greater than 5% of the population within 5 miles. This call is being placed due to the relatively large segment of the population affected [10 CFR 50.72(b)(3)(xiii)]. During an event, the Palo Verde Emergency Plan has a contingency for dispatching Maricopa County Sheriff's Office (MCSO) vehicles with loud speakers to alert persons within the affected areas when sirens are inoperable. In order to activate this contingency, Maricopa County Department of Emergency Management was notified of the failed siren at 12:58 [10 CFR 50.72(b)(2)(xi)]. | On December 04, 2007 at approximately 07:00 Mountain Standard Time (MST), the Palo Verde Emergency Preparedness Department discovered sirens 17, 18 and 23 out of service.
