Regularly scheduled low-volume tests of the early warning system sirens within the Diablo Canyon nuclear power plant's Emergency Planning Zone will be performed Tuesday and Wednesday.

Repeat: The sirens sounding Tuesday and Wednesday are only a test.

The San Luis Obispo County Office of Emergency Services announced Thursday that 131 sirens within the zone will sound at low-volume for a few seconds each, and there is no action required from the public.

The sirens cover an area from Cayucos south to the Nipomo Mesa, the Five Cities area, Avila Bay, the See Canyon and Squire Canyon areas, Price Canyon, Baywood Park/Los Osos, Morro Bay and the city of San Luis Obispo.

The early warning system was installed and is maintained by the county and Pacific Gas & Electric Co. as a requirement for the operation of Diablo Canyon, but the sirens also will be used in any local emergency such as tsunami, dam failure or other disasters.

In the case of a real activation of the emergency alert system, the public should tune to a local television or radio station for emergency information.
