Press Release, St. Mary’s County Public Information Office 

Leonardtown, MD – A full-cycle test of the alert and notification sirens throughout St. Mary’s, Calvert and Dorchester counties will take place on Monday, December 3 at noon.

The test includes a three-minute activation of all sirens within the 10-mile area around the Calvert Cliffs Nuclear Power Plant. Citizens are asked to remember the scheduled testing and relay the information to friends, family and neighbors.

Testing is conducted to check siren operation and increase public awareness of the alert and notification siren system. If the sirens sound at any other time, residents should tune to one of the local radio stations for information and instructions.

Knowing what to do before, during and after an emergency is a critical part of being prepared and may make all the difference, when seconds count
