Pacific Gas and Electric Co. will be conducting a series of growl tests Tuesday and Wednesday on its network of emergency warning sirens.
The tests will last from 8 a.m. to 4 p.m. on both days, said Tom Cuddy, PG&E spokesman.
PG&E maintains a network of 131 sirens in San Luis Obispo County from Cayucos to the Nipomo Mesa and as far inland as San Luis Obispo that would be sounded in the event of radiation release at Diablo Canyon nuclear power plant. The sirens can also be used during any other kind of public safety emergency.
The sirens are partially sounded several times a year in what are called growl tests. They are fully tested once a year, usually during the summer.
