For Immediate Release - December 03, 2012


At 12:30 p.m. on Wednesday, December 5, 2012, the Commonwealth of Massachusetts and the state of New Hampshire, in conjunction with Seabrook Nuclear Power Station, will conduct an audible demonstration of all 121 of the Public Alert and Notification System (PANS) sirens that are located within Seabrook Station’s 10-mile Emergency Planning Zone (EPZ).  There are 27 sirens located in Massachusetts, within the communities of Amesbury, Merrimac, Newbury, Newburyport, Salisbury and West Newbury, with 94 in New Hampshire.

While the PANS sirens can be used to notify the public of any kind of emergency (i.e. weather, homeland security event, etc.), the purpose of this December 5th demonstration is to provide the public within the 23 Seabrook Station EPZ communities an opportunity to again hear the siren tone that would be utilized by Massachusetts and New Hampshire to alert the public of an emergency at Seabrook Station. 

The siren demonstration will last from 3-5 minutes, and will be ending at approximately 12:35pm.  No public action will be necessary.

The demonstration is intended to complement information published annually in the Emergency Public Information Calendars for Neighbors of Seabrook Station in Massachusetts and New Hampshire.  The annual emergency public information calendars advise the public that if they hear the PAN siren tone, for three to five minutes, tune to the Emergency Alert System (EAS) radio station for their state (93.7 FM, 92.5 FM, 98.5 FM, 1030 AM, and 1450 AM in MA; 97.5 FM in NH) for specific information and directions.  The demonstration is intended to reinforce that message.

The siren demonstration, conducted by the Massachusetts Emergency Management Agency (MEMA), in conjunction with the New Hampshire Division of Homeland Security & Emergency Management (NHHS & EM) and the utility, is in compliance with the regulations of the Federal Emergency Management Agency (FEMA) to ensure the effectiveness of the public notification system. 

Notifications of this event have been disseminated to the public through local stakeholder meetings, mailings to households, traditional Media outlets, Social Media (Facebook and Twitter), and on Wednesday morning via ping4alerts! (MEMA’s new mobile communications app for alerting the public in emergencies and disasters).
