Dear IPC Member:
SUBJECT:
SONGS Community Alert Siren System. Test The annual test of the Community Alert Siren System surrounding the San Onofre Nuclear Generating Station, as required by the Federal Emergency Management Agency, is scheduled for Wednesday, September 22, 1993.
All 52 sirens around the plant will sound twice for two to five minutes each time between 10:00 am and noon.
They will be heard in the area around the plant, includingSan Onofre State Park and Camp Pendleton, and the cities of San Clemente, San Juan Capistrano and Dana Point.
As in the past, public awareness of the test will be enhanced by a direct-mail notice to every customer in the Emergency Planning zone, posters to beach and park visitors, video tape to local public facilities, care facilities, hotels and cable companies and a news release (see attached ).
In addition, a radio message will be submitted through the Emergency Management Division for activation of the Emergency Broadcast System on the morning of the test. A copy of the Community Alert Siren System is enclosed for your information.
It is possible, but unlikely, that your customer telephone information personnel may receive calls regarding the siren test. Such calls may be referred to me at PAX 88334.
Sincerely, J'Tck E. Wallace Supervisor, Emergency Planning Enclosure 9312010249 930916 PDR ADOCK 05000206 P
