Residents in the 10 miles around the Limerick Generating Station will hear sirens on Monday, April 2 when Exelon Nuclear conducts a test of its new siren system.
Beginning at 2 p.m., residents will hear two sets of tones lasting three minutes each. All testing will be done by 2:30 p.m.
The required tests are part of Exelon's plan to replace all 165 emergency sirens in the 10 miles around the Limerick Generating Station with state-of-the-art sirens that include battery back up.
The effort is part of a $13 million investment to upgrade emergency sirens at Exelon Nuclear stations.
Residents may contact the counties if they have concerns during testing: Montgomery County (610) 631-6530; Berks County (610) 374-4800; and Chester County (610) 344-5000.
The sirens are one of several methods used by county emergency managers to warn of emergencies. They may include fires, floods, tornados, hazardous material releases, or nuclear energy plant events.
The sirens are not a signal to evacuate. In an actual emergency, residents would tune to one of the county Emergency Alert System radio frequencies or television stations for instructions.
