What is the Community Alert Siren System?

In the unlikely event of an emergency at the San Onofre Nuclear Generating Station (SONGS), federal regulations require that an alert and notification system be in place to help protect the health and safety of the public. The Community Alert Siren System is a network of sirens strategically located within the plant's Emergency Planning Zone (EPZ) to provide that service. The EPZ is the area surrounding SONGS and includes:

• City of Dana Point
• City of San Clemente
• City of San Juan Capistrano
• Marine Corps Base Camp Pendleton
• California State Parks
• Orange County (unincorporated areas south of Ortega Highway)

Remember - This is Only a Test

You do not need to take action. Please do not call 911.

Federal regulations require that this test be conducted each year.

You will hear a long, steady siren sound. The sirens will be sounded several times for approximately three minutes each time.

Sirens will be heard in Dana Point, San Clemente, San Juan Capistrano, State Parks, Marine Corps Base Camp Pendleton, and throughout the unincorporated areas of Orange County within 10 miles of the plant.

In some areas, a separate test of the Public Address feature may be conducted. This feature may be used to alert local populations to other emergencies or to provide specific directions.
