Testing of new Peach Bottom warning siren system to begin Wednesday

The Harford County Department of Emergency Services, in conjunction with Exelon Power, is notifying residents about testing dates this month and next for a new emergency warning siren system for the Peach Bottom Atomic Power Station in neighboring York County, Pa.

The testing, which begins Wednesday and will run weekly into early August, is being conducted in accordance with the Federal Emergency Management Agency requirements for new siren systems, according to a department of emergency services news release.


The sirens are not a signal to evacuate, the news release emphasizes, noting that while the sirens are an outdoor waning system, they may be heard indoors during the testing. In an actual emergency, residents should tune to the Emergency Alert System radio or television stations for further information.

Exelon, which owns the nuclear generating plant, has installed a new state-of-the art siren system within Peach Bottom's 10-mile Emergency Planning Zone, which includes northern Harford County. According to the new release, the 97 new outdoor warning sirens incorporate a battery powered backup system and an upgraded communication system that enable full functionality in the event of an electrical power outage.


The testing will involve a full volume three minute sounding of the sirens and will occur on the following dates and times:

• Wednesday, July 17, 1 p.m.
