Interagency Incident Management Group

The Interagency Incident Management Group is a multi-agency coordinating entity that integrates capabilities from federal, state, tribal, and local partners for large-scale disaster response and complex wildfire incidents. It combines personnel and authorities drawn from Federal Emergency Management Agency, United States Forest Service, Bureau of Land Management, National Park Service, and other agencies to provide unified incident command system leadership, strategic planning, and resource allocation. The group operates within the National Incident Management System framework and often interfaces with regional entities such as the FEMA Region 9 and interagency centers like the National Interagency Fire Center.

Overview

The Interagency Incident Management Group serves as an interoperable cadre that aligns policy from Department of Homeland Security, United States Department of Agriculture, Department of the Interior, and state-level emergency management offices to support incident objectives. It delivers strategic incident management, logistics coordination, finance and administration oversight, and public information integration among partners including State Emergency Operations Center (EOC), Tribal Emergency Management Offices, and municipal emergency services. The group’s remit frequently overlaps with specialized teams such as Incident Management Teams (IMTs), BlueSky-type mapping units, and regional coordination centers like the Western Regional Coordination Center.

History and Development

The IIMG concept evolved from cross-agency collaboration dating to post-1988 Yellowstone fires reforms and the establishment of the Federal Emergency Management Agency reorganization in the 1990s. Influences include lessons learned from the 1991 Oakland Hills firestorm, the multi-jurisdictional responses to Hurricane Katrina, and the institutionalization of the National Incident Management System after the September 11 attacks. Interagency protocols codified through the National Response Framework and memoranda among the United States Forest Service and Bureau of Land Management shaped the modern IIMG structure. Significant milestones include adoption of common standards from the Incident Command System and joint exercises with entities such as the National Guard Bureau and Centers for Disease Control and Prevention.

Organization and Composition

An IIMG typically comprises senior representatives from federal agencies—Federal Emergency Management Agency, United States Forest Service, Bureau of Land Management, National Park Service, United States Fish and Wildlife Service—as well as state emergency management directors, tribal leaders, and municipal emergency chiefs. Functional sections mirror the Incident Command System: Command, Operations, Planning, Logistics, and Finance/Administration, staffed by personnel credentialed through programs like the Emergency Management Institute and interagency qualification standards such as the Red Card system used by wildland fire communities. Liaison roles often include officers from Environmental Protection Agency, Department of Transportation, Federal Communications Commission, and regional National Weather Service offices to ensure cross-domain integration.

Roles and Responsibilities

IIMG responsibilities include establishing incident objectives that reconcile policy from Department of Homeland Security and Office of the President guidelines, coordinating multi-jurisdictional resource requests through mechanisms like the Emergency Management Assistance Compact and federal mission assignments, and overseeing strategic demobilization plans. The group provides unified public information products in coordination with Department of Health and Human Services and state public health authorities, advises on hazardous materials mitigation with the Environmental Protection Agency, and manages interagency logistics via partnerships with General Services Administration and Defense Logistics Agency where applicable.

Activation and Deployment

Activation of an IIMG can be triggered by state governor requests, regional FEMA activation, or interagency agreements during escalating incidents such as major wildfires, hurricanes, or radiological events. Deployment protocols reference the National Response Framework, state emergency declarations, and mutual aid compacts including the Emergency Management Assistance Compact. Once activated, the group establishes an Incident Command Post or Area Command near the affected region—typical coordination nodes include National Interagency Fire Center and regional FEMA Regional Response Coordination Centers—and coordinates with tactical assets like Type 1 Incident Management Teams and regional strike teams.

Training, Qualifications, and Certifications

Personnel assigned to IIMG roles are commonly required to complete standardized courses from the Emergency Management Institute, National Wildfire Coordinating Group training modules, and position-specific qualifications tracked through systems such as IQCS and interagency credentialing programs. Certifications include professional credentials like the Certified Emergency Manager designation and wildland qualifications documented by the Incident Qualifications and Certification System. Regular joint exercises, including national-level exercises coordinated with FEMA National Exercise Division and regional drills with the National Guard Bureau, maintain interoperability and readiness.

Notable Operations and Case Studies

IIMG formations have been integral to responses for incidents including the multi-state coordination during Hurricane Irene and Hurricane Sandy, complex wildland fire campaigns such as the Camp Fire (2018) and large-scale incidents following the 2017 California wildfires. Case studies highlight interagency coordination during the Deepwater Horizon oil spill, where federal, state, and tribal authorities leveraged joint incident management practices, and in cross-border emergency scenarios involving collaboration with United States–Mexico border agencies. After-action reports from events like Hurricane Maria informed updates to IIMG protocols and influenced policy changes within Department of Homeland Security and associated agencies.
