Siren Testing Continues July 14 for Nuclear Plants

FULTON – Full volume tests of the new sirens installed by Exelon Generation and Entergy Nuclear will continue Tuesday, July 14 and Tuesday, July 28, with three-minute soundings of all sirens at once at approximately 10 a.m.

Postcards mailed to residents of the 10-mile Emergency Planning Zone surrounding the nuclear power plants inadvertently gave an incorrect date on the full-system tests.

The tests on July 14 and July 28 could be followed by short bursts (growl tests) of individual sirens if any issues are identified.

On Wednesday, Aug. 12, four three-minute soundings will be held throughout the day beginning at 9 a.m. During these tests, technicians will be stationed near the siren sites to verify that the actual sound coverage is the same as what was predicted in the design. The rain date for these tests is Thursday, Aug. 13.

The installation project is a joint effort by Exelon Generation, which owns and operates Nine Mile Point Nuclear Station, and Entergy Nuclear, which owns and operates the James A. FitzPatrick Nuclear Power Plant, to upgrade the public warning system.  It includes replacing the 37 existing sirens and installing two additional sirens, as well as the addition of battery backup-power to all 39 sirens in the 10-mile radius around the nuclear power plants.

The system is operated by Exelon Generation and serves both of Oswego County’s nuclear facilities. In an emergency, the sirens would be sounded prior to an Emergency Alert System message on broadcast stations participating in the Oswego County Emergency Alert System, which would tell people why the sirens sounded and what they should do. “The sirens are not a signal to evacuate,” Oswego County Emergency Management Office Director Dale A. Currier stressed. “People should always consult an EAS station to hear instructions by Oswego County officials on what they should do.”

EAS stations are listed in the 2015 Public Emergency Response Information Calendar, available on the Oswego County website at www.oswegocounty.com/emo.
