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.
For questions related to this siren test, please call the Catawba Nuclear Station (800-777-0006, select option 1). Questions about the tests can also be directed to county emergency management agencies.
Catawba Nuclear Station is owned jointly by North Carolina Municipal Power Agency Number 1, North Carolina Electric Membership Corp., Piedmont Municipal Power Agency and Duke Energy.
