If there were an actual emergency at the 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. During an emergency when sirens sound, residents should listen to local officials and local media outlets that broadcast emergency information for updates and instructions.
Emergency guides are mailed to surrounding households and additional information about the siren system, emergency notifications and safety planning can be found on Dominion Energy’s website.
Siren tests take place at the North Anna Power Station quarterly on the third Wednesday of the month for 2018: February 21, May 16, August 15 and November 21.
