CDC Support for the Emergency Management Assistance Compact (EMAC)

Ratified by Congress and signed into law in 1996, the Emergency Management Assistance Compact (EMAC) is an interstate mutual aid agreement that provides a mechanism for sharing personnel, equipment and resources among states during emergencies and disasters. EMAC has traditionally been used by states for National Guard, emergency management and other types of response assistance. More recently, it has been used to provide public health and medical assistance with much success. Some benefits of using EMAC include

  • Increased collaboration among states during emergency preparedness, response and recovery;
  • Better awareness and understanding of state and local needs;
  • Increased access to personnel, equipment and resources;
  • Consideration of legal issues related to worker compensation, liability, credentialing and reimbursement.

All 50 states, three territories (U.S. Virgin Islands, Puerto Rico and Guam), and the District of Columbia have enacted legislation to become members of EMAC. To use EMAC in the most effective manner possible, health departments are encouraged to collaborate with their emergency management agencies and other response partners to increase their awareness and understanding of the EMAC system, organization, components and principles. Health departments are also encouraged to participate in education and training on EMAC whenever possible.

The Centers for Disease Control and Prevention's (CDC) National Center for Environmental Health (NCEH), Division of Emergency and Environmental Health Services (EEHS) coordinates the EMAC Environmental Health Assistance Initiative.

  • Encourage the increased use of EMAC among states in the provision of public health and environmental health assistance and resources during emergencies and disasters;

  • Define and establish the roles of CDC in providing consultation, technical expertise and support to public health and environmental health departments during emergencies and disasters when EMAC is being used to provide state-to-state assistance and resources.

CDC facilitates and supports efforts to provide education, awareness and training on EMAC to local, state and federal public health professionals.
