State and local officials will test the early warning siren system around the North Anna Power Station Wednesday, Nov. 21, 2012, at approximately 11:10 a.m. A steady three-minute tone will be sounded by 68 sirens in Caroline, Hanover, Louisa and Spotsylvania counties.
The sirens are located within a 10-mile radius of the plant. Siren tests take place quarterly on the third Wednesday of February, May, August and November. The Virginia Department of Emergency Management, Dominion Virginia Power and the localities where the sirens are located participate in the quarterly tests. If there were an actual emergency at North Anna Power Station, residents would hear four separate three-minute activations, each separated by a one-minute silent interval. Total elapsed time for actual emergency notification is 15 minutes. When sirens sound, people should listen to a local radio or TV station that is broadcasting emergency information for instructions.
Additional information about the siren system and emergency notification can be found in the annual North Anna Power Station emergency information calendar mailed to households in the region. The next test of the North Anna siren system will be Wednesday, Feb. 20, 2013.
