Both Intrastate Mutual Aid Compact (IMAC) the Emergency Management Assistance Compact (EMAC) are tools to connect Parishes with needed resources.

Difference Between IMAC + EMAC

Created by an act of the State Legislature, IMAC is an intrastate agreement that enables Parish-to-Parish assistance when a mutual aid agreement (MAA) between Parishes is not already in place.

EMAC is an interstate mutual aid compact providing State-to-State assistance and requiring an agreement between States.

Louisiana State Police officers were deployed to assist the state of New Jersey following Hurricane Sandy in response to a direct request through EMAC.


IMAC is a developing program that provides and promotes mutual assistance in the prevention of, response to and recovery from an emergency or any other event that exceeds a Parish’s resource capability. The system was created by Louisiana Revised Statute (LRS) Title: 29:739 and enables Parish-to-Parish assistance when a mutual aid agreement between Parishes is not already in place. 

By executing an IMAC request, authorized representatives from both the assisting and requesting Parish, enter into a contract to provide and reimburse for services to be rendered under the IMAC.

Parishes requesting assistance, Parishes providing assistance and the State have specific responsibilities when using the IMAC system.

Requesting Parish Must . . .

  • Declare a State of Emergency prior to requesting assistance.
  • Document the mutual aid process from declaration through reimbursement.
  • Identify what resources are needed.
  • Agree on a price and scope.

Assisting Parish Must . . .

  • Verify the details of the request for assistance.
  • Ensure receipt of proper authorization from a requesting Parish prior to deploying resources.
  • Agree on price and scope.

Both Requesting + Assisting Parish Must . . .

  • Utilize the State emergency management process (In WebEOC) for requesting assistance.
  • Adhere to guidelines set forth in the National Incident Management System (NIMS).
  • Participate in an After-Action Review (AAR) and implement corrective actions.

State Responsibilities

  • Overseeing and maintaining the State emergency management process in order to facilitate the IMAC process.
  • Maintaining Parish authorization representative list.


The Emergency Management Assistance Compact (EMAC) is a nationally adopted mutual aid agreement (MAA) that enables States to share resources during emergency events or disasters.

EMAC has been ratified by Congress and is law in all 50 states, the District of Columbia (DC), Puerto Rico, Guam and the U.S. Virgin Islands. EMAC was passed by the U.S. Congress in 1996 as Public Law 104-321. EMAC acts as a complement to the national disaster response system, providing timely and cost-effective assistance to disaster-impacted States and is the Nation’s most efficient, effective and preeminent interstate mutual aid system.

EMAC is implemented by the State emergency management agency on behalf of the Governor. EMAC requests must go through GOHSEP.

How EMAC Works

  • Governor declares a state of emergency due to a natural or man-made emergency or disaster.
  • Resource needs and identifies shortfalls for which assistance is needed.
  • State requests resources from EMAC member States through the State emergency management agencies.
  • State emergency management personnel and local resource provider’s work together to identify available resources and estimated mission costs.
  • Resources are sent to the Requesting State from the Assisting State (i.e. mobilized and deployed).
    Requesting State reimburses Assisting State.

Developing Your Response-Specific Mission Ready Package

When disaster strikes, immediate access to essential resources is necessary if emergencies and disasters are to be managed effectively.

Mission Ready Packages (MRPs) are specific response and recovery capabilities that are organized, developed, trained and exercised prior to an emergency or disaster — YOU can help make this happen.

MRPs are based on NIMS resource typing – defining and categorizing, by capability, the resources requested, deployed and used in incidents – and taking the concept one step further by considering the:

  • Mission.
  • Limitations that might impact the mission.
  • Equipment, commodities and required support.
  • Footprint of the space needed to stage and complete the mission.
  • Estimated costs.

MRPs also include credentialed personnel – those who are identified by the Resource Provider as having the knowledge, skills and abilities needed to conduct the specific mission for which MRP is to be deployed.

Resource Providers should work in cooperation with State emergency management agencies to develop MRPs.
