Wyoming Office of Homeland Security: Emergency Preparedness

The Wyoming Office of Homeland Security (WOHS) coordinates emergency preparedness, mitigation, response, and recovery operations across Wyoming's 23 counties and 2 incorporated municipalities classified as cities. Operating under the Wyoming Governor's Office, WOHS functions as the primary state-level interface between federal emergency management infrastructure and local government emergency managers. This reference covers the agency's structural authority, operational mechanisms, common activation scenarios, and the boundaries that define its jurisdiction versus adjacent federal and local responsibilities.

Definition and scope

The Wyoming Office of Homeland Security is established under Wyoming Statute Title 19, Chapter 13, which governs civil defense and emergency management within the state. WOHS holds statutory authority to develop and maintain the Wyoming Comprehensive Emergency Management Plan (CEMP), coordinate resource allocation during declared emergencies, and administer federal preparedness grant programs distributed through the Federal Emergency Management Agency (FEMA).

The agency's scope encompasses four recognized emergency management phases:

  1. Mitigation — Pre-disaster actions to reduce the likelihood or impact of hazardous events, including hazard vulnerability assessments and floodplain management coordination.
  2. Preparedness — Training programs, exercise design, public alert system maintenance, and county Emergency Operations Plan (EOP) development.
  3. Response — Activation of the State Emergency Operations Center (SEOC), resource deployment, and interagency coordination during active incidents.
  4. Recovery — Administration of disaster assistance programs, federal reimbursement facilitation, and long-term community restoration coordination.

WOHS administers the Homeland Security Grant Program (HSGP) and the Emergency Management Performance Grant (EMPG), both funded through FEMA (FEMA Homeland Security Grant Program). EMPG funding requires a 50% cost-share match from the state or local recipients, a condition established under 6 U.S.C. § 762.

Scope and coverage limitations: WOHS authority applies to all 23 Wyoming counties and municipalities operating under Wyoming law. It does not apply to federal lands administered by the Bureau of Land Management, National Park Service units, or operations falling exclusively under tribal sovereignty on the Wind River Reservation. Emergency management operations on the Wind River Reservation are governed by Eastern Shoshone and Northern Arapaho tribal governments, with coordination through the Wyoming Tribal Government Relations framework. Interstate emergency compacts, such as the Emergency Management Assistance Compact (EMAC), activate WOHS authority to request or provide resources across state lines, but command authority over out-of-state resources remains with the originating state.

How it works

WOHS operates the State Emergency Operations Center in Cheyenne, which activates at one of three operational levels depending on incident severity. Level 3 represents routine monitoring; Level 2 represents partial activation with relevant agency liaisons; Level 1 represents full activation with 24-hour staffing across all Emergency Support Functions (ESFs).

The 15 ESFs, defined by the National Response Framework (FEMA National Response Framework), assign lead and support agencies to functional areas including transportation, communications, firefighting, mass care, and public health. WOHS serves as the coordinating body, while operational lead for each ESF may fall to a different state agency — for example, the Wyoming Department of Health leads ESF-8 (Public Health and Medical Services) and the Wyoming Department of Transportation leads ESF-1 (Transportation).

County Emergency Managers, employed at the county level but operationally linked to WOHS through required EOP submissions and annual compliance reviews, serve as the primary local points of contact. Wyoming has 23 county emergency managers, one per county, each responsible for maintaining a locally adopted emergency operations plan that conforms to WOHS standards.

The Wyoming Information Analysis Center (WIAC), co-located with WOHS, functions as the state fusion center for threat intelligence, connecting local law enforcement, federal agencies, and WOHS into a shared situational awareness network consistent with the 28 C.F.R. Part 23 standards for criminal intelligence systems.

Common scenarios

Wyoming's geographic and demographic profile — low population density, high wildland-urban interface exposure, significant pipeline and energy infrastructure, and seismic activity near Yellowstone — produces distinct emergency activation patterns.

Wildfire: Wyoming's largest wildfire events trigger coordinated activation between WOHS, the Wyoming State Forestry Division, and the U.S. Forest Service. The SEOC may reach Level 1 activation when fires exceed local suppression capacity, typically measured in acreage thresholds specified in the CEMP. Under EMAC, Wyoming may request strike teams from adjacent states when in-state resources are exhausted.

Severe weather and flooding: Wyoming experiences rapid weather transitions, particularly in mountainous terrain. Flash flooding in areas such as Park County and Fremont County requires coordination between the National Weather Service and county emergency managers operating under WOHS protocols.

Hazardous materials incidents: Wyoming's energy sector, including crude oil pipelines, natural gas infrastructure, and coal transport corridors, creates hazmat risk concentrations. WOHS coordinates with the Wyoming Department of Environmental Quality (WDEQ) and the Pipeline and Hazardous Materials Safety Administration (PHMSA) under shared regulatory authority.

Public health emergencies: Declared public health emergencies bring WOHS into operational coordination with the Wyoming Department of Health. The Wyoming Department of Health retains primary statutory authority under Title 35 health statutes, while WOHS provides logistics, communications infrastructure, and SEOC coordination support.

Decision boundaries

The critical operational distinction within Wyoming's emergency management structure is the difference between a gubernatorial disaster declaration and a local emergency declaration.

A local emergency declaration, issued by a county commission or municipality, activates local EOPs and may request state resource assistance without triggering WOHS SEOC full activation. A gubernatorial declaration — issued under Wyoming Statute § 19-13-111 — activates the full emergency powers framework, enables state agency resource redirection, and positions Wyoming to request a Presidential Major Disaster Declaration through FEMA under the Robert T. Stafford Disaster Relief and Emergency Assistance Act (42 U.S.C. § 5121 et seq.).

Presidential Major Disaster Declarations unlock federal assistance categories including Public Assistance (PA), Individual Assistance (IA), and Hazard Mitigation Grant Program (HMGP) funding. PA cost-share is typically set at 75% federal / 25% state-local, though FEMA may adjust the federal share under exceptional circumstances (FEMA Public Assistance Program).

WOHS does not hold independent law enforcement authority. That authority rests with the Wyoming Attorney General and county sheriffs. WOHS also does not administer unemployment or social services during disasters — those functions belong to the Wyoming Department of Workforce Services.
