Exelon to test all TMI warning sirens today
Exelon Generation will conduct its semi‑annual, full volume test of the emergency warning sirens surrounding Three Mile Island Generating Station today, June 2, at approximately 12:15 p.m. This is one of two semi‑annual tests performed each year.
The TMI emergency warning siren system consists of 96 sirens located in parts of Cumberland, Dauphin, Lancaster, Lebanon and York counties that are located within a 10‑mile radius of TMI. The purpose of the sirens is to alert residents to tune to an Emergency Alert Broadcast Station for information from
Pennsylvania state officials. During the test the Emergency Alert Broadcast System will not be activated.
