Duke Energy and County Officials to Test Sirens around Catawba Nuclear Station

  • Three-minute test scheduled between 11 a.m. and 1 p.m. on Wednesday, April 14
  • No public action required

YORK, S.C. – The outdoor warning sirens around the Catawba Nuclear Station will be tested between 11 a.m. and 1 p.m. on Wednesday, April 14.
The 89 sirens within 10 miles of the Catawba Nuclear Station will sound for three minutes. To ensure they are functioning properly, it may be necessary to test some sirens more than once. Testing is performed in cooperation with emergency officials in York, Gaston and Mecklenburg counties, who are responsible for sounding the sirens.

This information is reflected in the 2021 Catawba Nuclear Station Preparedness booklets sent to residents living within the 10-mile Catawba Nuclear Station emergency planning zone.

Because this is a test, local broadcasting stations will not interrupt regular programming to broadcast Emergency Alert System (EAS) messages. If there were ever a real emergency at the plant requiring the sirens to be sounded, local radio and television stations would broadcast information and instructions to the public.
For more information about the outdoor warning sirens, residents can refer to information available at duke-energy.com/NuclearEP.
