DENVER––Some Denver residents probably wondered why they were hearing a siren Thursday morning.

But according to Lincoln County Operations Co-ordinator Ronald Rombs, there was no cause for alarm. As Rombs explained Thursday, citing Charlotte-Mecklenburg Emergency Management, an inadvertent siren activation for the McGuire Nuclear Station came that morning at 10 a.m., sounded by Charlotte Fire Communications. A silent test, which typically happens weekly per established procedures, was intended.

There was and is no existing cause for concern. There was and is no emergency, and no action is required. Residents were asked not to call 911 to report the sounding of the siren. Notifications were issued as soon as possible.

Public safety agencies, as well as Mecklenburg County leadership officials, were notified. Additionally, the McGuire Nuclear Task Force has been working with the Charlotte-Mecklenburg Emergency Management Office (or CMEMO), Duke Energy and North Carolina Emergency Management (or NCEM) to ensure that all residents, businesses and supporting agencies have been notified.

Duke Energy also released a statement on the matter. It reads:

“The McGuire Nuclear Station is operating safely. There is no emergency at the station. As a reminder, if you hear sirens and are not sure if it is a test or emergency, tune to a local radio or television station in your area. During an emergency, these stations stop regular programming to provide information to the public. Duke Energy is working with local county and state emergency management to determine the cause of the inadvertent siren activation. Again, the McGuire Nuclear Station is operating safely.”
