The specific cause of this siren being inoperable has not been determined. Based on evidence from previous testing, this loss of siren #36 has been established to have occurred sometime between 22:00, Friday, 03/11/2005 and 03:00, Saturday, 03/12/2005. The affected siren is estimated to impact approximately 82 members of population (5.1 %) in the emergency planning zone (EPZ) within 5 miles.
