The Harris Nuclear Plant's annual full-volume siren test will be conducted Tuesday, Sept. 22 between 10 - 11 a.m.

The 83 alert notification sirens within 10 miles of Progress Energy's Harris Plant will be tested at full-volume for approximately 3 minutes. This test is conducted in cooperation with the State of North Carolina as well as Chatham, Harnett, Lee and Wake counties.

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. In the event of severe weather, the siren test will be postponed until a later date.

Progress Energy performs full-volume tests annually. Silent tests are conducted every two weeks and short duration full-volume tests every three months.

Questions about the tests may be directed to county or state emergency management agencies.

Residents with questions may also call the Harris Plant at (919) 362-3261.
