The Contra Costa County Community Warning System (CWS), a partnership between government, industry and news media to alert and inform the community in case of an emergency, is scheduled to conduct tests of its telephone alert system tonight.
Tests of the Telephone Emergency Notification System (TENS) — which includes voice calls to landlines and cellphones, as well as text messages and emails to devices pre-registered with CWS — will occur between 5:30 p.m. and 8:30 p.m. countywide.
The tests in the Richmond/San Pablo area surrounding the Chevron Richmond Refinery will occur at 7 p.m.
Below are the times in which testing in other zones will occur:
5:30 PM—Pittsburg/Antioch areas surrounding Dow Chemical facility
6:00 PM—Martinez/Pacheco area surrounding Shell Refinery
6:30 PM—Crockett/Rodeo area surrounding Phillips 66 Refinery
Those receiving the alert will see the phone number listed as 000-000-0000. During the tests, you should also see this message:
“This is a test of the telephone portion of the Contra Costa County Community Warning System. This is only a test. There is currently no emergency in your area. For more information about this test or to register to receive alerts on your cell phone or email during actual emergencies go to www.cococws.us or do an Internet search for CWS Alerts. This is only a test.”
The testing will examine call capacity, capabilities and quality of the TENS vendor for the CWS. Following the test, a brief online survey will be offered to residents to determine call quality and system behavior. For the survey, go to www.cococws.us. At this time, CWS will NOT be testing sirens, Emergency Alert System, NOAA weather radios, Facebook or Twitter.
