 TMI to Conduct Annual Siren Test 

 Three Mile Island will test all 96 emergency sirens 

 

LONDONDERRY TOWNSHIP, PA (June 21, 2010) – On Thursday, June 24 at 12:15 p.m. EDT all 96 emergency notification sirens in the 10-mile radius around Three Mile Island Generating Station will be sounded for three minutes.  Exelon Nuclear is conducting the test in cooperation with Cumberland, Dauphin, Lancaster, Lebanon and York Counties and the Pennsylvania Emergency Management Agency (PEMA). 

A full three-minute sounding of the sirens is required on an annual basis.  TMI conducts routine electronic testing of the sirens on a weekly basis. 

Cumberland, Dauphin, Lancaster, Lebanon, and York counties will activate the sirens from their county 911 Communications Centers.  Personnel from TMI cannot sound the sirens; only county emergency management officials have the capability and authority to do so. 

The purpose of the sirens is to notify residents to tune into an Emergency Alert System (EAS) radio or television station in case of an emergency at TMI or tornadoes, floods, or other events requiring notification to residents.
