Emergency Management Assistance Compact logo

What is EMAC? The Emergency Management Assistance Compact (EMAC) is a congressionally ratified mutual aid compact that legally establishes a national system to facilitate resources across state lines during an emergency or disaster.  

Its ratification in 1996 as Public Law 104-321 made EMAC the first national disaster compact to be ratified by Congress since the Civil Defense Act of 1950.

  • Is EMAC an organization? +

    EMAC is not an organization but, rather, an agreement between states.

    The Compact is administered by the National Emergency Management Association (NEMA), a professional nonprofit association of, and for, state emergency management directors—but EMAC is not in itself an organization.

  • What does "state" mean in terms of EMAC membership? +

    When referring to “states” in terms of EMAC, what does “state” mean? Only the fifty states of the nation?

  • How many states are members of EMAC? +

    To date, all fifty states, the District of Columbia, Puerto Rico, Guam, and the U.S. Virgin Islands are EMAC members.

  • What makes EMAC different from other mutual aid agreements? +

    EMAC’s distinctive character among mutual aid agreements lies in its governance structure; its relationship with states, regions, territories, national membership, and federal organizations; and its ability to move any type of needed resource from one state to another.

  • Who administers EMAC? +

    NEMA logoThe National Emergency Management Association (NEMA) has administered EMAC since 1995.

    NEMA is the professional association of and for emergency management directors from all fifty states, eight territories, and the District of Columbia.

  • What types of resources may be deployed through EMAC? +

    EMAC resources may include any capabilities — no matter how large or small, how typical or specialized — that one member state possesses that can be shared with another member state. The law says that states will make use of all of the resources within their state to make them deployable through EMAC (including local government resources). 

    With such resources as emergency operations center support, disaster recovery, security, fire fighting, law enforcement, medical personnel and resources, public utilities management, public health, GIS support, engineering, transportation, and community outreach, the capabilities that states can share with one another are nearly limitless.

  • Who provides workers compensation benefits? +

  • Who provides tort liability and immunity under EMAC? +

    Tort liability and immunity protection is provided by the Requesting State under EMAC law so long as personnel are acting in good faith.
