Sirens around Oconee Nuclear Station will be tested Wednesday, January 9 around 11:50 a-m. No public action is required during the three-minute test. By testing the sirens, state and county officials and Duke Energy ensure the sirens are operating properly. The full-cycle test is scheduled once every three months. County officials are responsible for sounding the sirens. Hearing a siren does not mean to evacuate. The siren sounding is a signal for residents to tune to a radio or TV station in their area that would carry an emergency alerting message. County officials would use the stations to provide information to the public.
