There are three types of mutual aid agreements, which can be utilized by communities and state agencies. This includes intrastate, interstate and international agreements.    

Intrastate Mutual Aid

Massachusetts has two types of intrastate mutual aid programs:

  • Statewide Mutual Aid Agreement — Cities and towns in Massachusetts that choose to opt in to this agreement can request emergency response assistance from any participating community in the state. Statewide mutual aid opt-in communities pdf format of Statewide Mutual Aid Map

The mutual aid agreement is defined by Massachusetts General Law Chapter 40 Section 4J, which specifies the handling of legal issues related to the lending of resources between cities, towns, and government entities.
  • Public Works Mutual Aid Agreement Public works mutual aid opt-in communities pdf format of Public Works Mutual Aid Opt In Communities
can send or request mutual aid for everyday purposes, rather than during a public safety emergency. This mutual aid agreement is outlined in Massachusetts General Law Chapter 40, Section 4K. Participating mutual aid communities also have advisory boards and are able to activate the agreement with neighboring out-of-state towns.

Interstate Mutual Aid

The Emergency Management Assistance Compact (EMAC) is an interstate agreement among all 50 states, the District of Columbia, Puerto Rico, the U.S. Virgin Islands, and Guam. EMAC enables the Governor to request disaster recovery assistance from other states after a declared state of emergency.

EMAC is governed by the National Emergency Management Association (NEMA).  This mutual aid agreement enables states to send emergency response equipment, personnel, assets, and commodities during times of natural, man-made, or technological disasters that pose a public safety threat. The mutual aid agreement is outlined in the Commonwealth’s Chapter 339 of the Acts of 2000.

EMAC is unique among mutual-aid compacts because it allows the deployment of any resource a state is willing to send to another state, including law enforcement, firefighting, public health, transportation and human services.

International Mutual Aid

The International Emergency Management Assistance Compact (IEMAC) is a mutual aid agreement between the Eastern Canadian provinces and the New England states. IEMAC functions similarly to the interstate mutual aid agreement, but the Governor is not required to declare a state of emergency in order to request assistance through IEMAC. The signatories of the mutual aid agreement, which is outlined in the Commonwealth’s Chapter 300 Section 58 of the Acts of 2002, are Massachusetts, New Hampshire, Connecticut, Rhode Island, Vermont, Maine, New Brunswick, Prince Edward Island, Nova Scotia, Quebec, and Newfoundland and Labrador.
