Mutual Aid Escalation and EMAC Framework
When local emergency management resources are overwhelmed, the mutual aid system provides a structured mechanism for obtaining assistance from other jurisdictions without pre-incident contracts for every possible resource type. Mutual aid operates in a tiered escalation. Local mutual aid: neighboring cities and counties have standing automatic mutual aid agreements (particularly common in fire services) that pre-authorize resource sharing without a formal request process — a neighboring fire department automatically responds to a major structure fire regardless of a formal request. Statewide mutual aid: the state emergency management agency (SEMA/OES/EMD, named differently by state) coordinates statewide resource sharing under a statewide mutual aid plan. Local emergency managers request state assistance when local resources are insufficient. Federal assistance: when state resources are exhausted, the governor requests a Presidential Disaster Declaration under the Stafford Act, triggering FEMA Individual Assistance and Public Assistance programs and federal resource mobilization. The Emergency Management Assistance Compact (EMAC) is the interstate mutual aid agreement ratified by all 50 states, DC, and most territories. EMAC allows states to request specific resources (personnel, equipment, or expertise) from other member states during declared emergencies. The requesting state provides a written EMAC request (a REQB — Request for Assistance) specifying the resource type, quantity, qualifications required, deployment duration, and location. The assisting state responds with an EMAC offer (OFAB — Offer of Assistance) specifying what resources are available, their credentials, and estimated arrival time. EMAC's critical legal protections: rendering state personnel (deployed out of state) have their professional licenses automatically recognized in the receiving state, have workers compensation covered by their home state, and are protected from liability for good-faith emergency actions under EMAC. These protections remove the major barriers that previously prevented interstate resource sharing.
