Duke Energy and County Officials to Test Sirens
Around McGuire Nuclear Station

HUNTERSVILLE -- Sirens located around McGuire Nuclear Station will be tested Wednesday, July 9, 2008, at approximately 11:50 a.m.
No public action is required during this three-minute test. By testing the sirens, state and county officials and Duke Energy ensure the sirens are operating properly. This full-cycle siren test is performed once each quarter. County emergency 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 these stations to provide information to the public.
