The Emergency Management Assistance Compact, or EMAC, is a state-to-state mutual aid agreement intended to provide material and personnel resources to states or territories affected by major disasters. It is designed to supplement disaster response resources that states possess on their own and resources that may be made available through the Federal Emergency Management Agency or other federal sources.
EMAC is supported administratively by the National Emergency Management Association. It evolved from a regional group of several southeastern states in the wake of Hurricane Andrew in 1992 to a compact of 49 states, Puerto Rico, the Virgin Islands and the District of Columbia in 2005.
An EMAC member requesting assistance sends an e-mail with the details of that request to all members of the group through their emergency management agencies. Responses are sent back to the requesting state or territory, which is responsible for making arrangements to accept the resource.
In New Hampshire, EMAC requests are processed through the Department of Safety's Bureau of Emergency Management. This Web page is used to make state, local or private agencies aware of pending requests and to notify BEM or available assets.
