Tennessee Emergency Management Agency: Disaster Preparedness and Response

The Tennessee Emergency Management Agency (TEMA) functions as the state's primary coordinating body for disaster preparedness, mitigation, response, and recovery operations. This page covers TEMA's organizational structure, its operational authority under Tennessee law, the categories of emergencies it addresses, and the boundaries that define when state-level intervention supersedes or supplements local and federal action.

Definition and scope

TEMA operates under Tennessee Code Annotated § 58-2-101 et seq., which establishes the Tennessee Emergency Management Act as the statutory foundation for statewide emergency management. The agency sits within the executive branch and works in direct coordination with the Tennessee Department of Safety and Homeland Security.

TEMA's mandate covers all 95 Tennessee counties, extending preparedness infrastructure to county-level Emergency Management Agencies (EMAs), which are required by state law to maintain local emergency operations plans. The agency administers federal grant funding distributed through the Federal Emergency Management Agency (FEMA), including Hazard Mitigation Grant Program (HMGP) funds and Emergency Management Performance Grants (EMPG). EMPG funding nationwide totaled $355 million in federal fiscal year 2023 (FEMA EMPG Program).

Scope boundaries and coverage limitations: TEMA's authority is bounded by Tennessee state law and applies exclusively within Tennessee's geographic and jurisdictional limits. Federal disaster declarations under the Robert T. Stafford Disaster Relief and Emergency Assistance Act (42 U.S.C. § 5121 et seq.) supersede or parallel state authority when the President formally declares a major disaster. Nuclear facility incidents on federally licensed sites fall under joint jurisdiction with the Nuclear Regulatory Commission and are not exclusively within TEMA's scope. Interstate compacts, including the Emergency Management Assistance Compact (EMAC), define mutual aid obligations between Tennessee and other signatory states but are governed by separate interstate agreement terms. Detailed information on the broader executive branch framework within which TEMA operates is available on the Tennessee Executive Branch page, and the full Tennessee government landscape is accessible through the Tennessee Government Authority site index.

How it works

TEMA's operational structure follows the National Incident Management System (NIMS) and the National Response Framework (NRF), both administered federally by FEMA. The agency activates the State Emergency Operations Center (SEOC) in Nashville at one of three operational levels:

1. Level 3 (Normal Operations): Routine monitoring, training, and grant administration. No active incident requiring centralized coordination.
2. Level 2 (Partial Activation): Specific agencies and Emergency Support Functions (ESFs) activated to address a localized or developing event. County EMAs may be engaged but incident command remains distributed.
3. Level 1 (Full Activation): Complete SEOC staffing across all 18 Emergency Support Functions. This level corresponds to events requiring statewide resource mobilization or a gubernatorial emergency declaration.

A gubernatorial emergency declaration under T.C.A. § 58-2-107 authorizes the suspension of specific regulatory statutes, activation of the Tennessee National Guard, and the request for federal major disaster or emergency declarations. The Governor may declare a state of emergency for up to 60 days without legislative concurrence; extensions beyond 60 days require General Assembly approval.

TEMA coordinates with the Tennessee Department of Health for public health emergencies, the Tennessee Department of Transportation for infrastructure damage assessment, and the Tennessee Department of Environment and Conservation for hazardous material releases and environmental remediation.

Common scenarios

Tennessee's geography and population distribution produce a recurring set of disaster categories that TEMA plans for and responds to:

• Severe weather and tornadoes: Tennessee lies within a secondary tornado corridor. The National Oceanic and Atmospheric Administration (NOAA) Storm Prediction Center records the state as averaging 15 tornadoes per year, with Middle Tennessee and West Tennessee counties at highest frequency.
• Flooding: Flash flooding is the most common natural disaster type in Tennessee. The 2010 Nashville flood caused an estimated $2 billion in damages (FEMA DR-1909-TN), making it one of the costliest natural disasters in Tennessee history.
• Hazardous materials incidents: Interstate highway corridors and industrial facilities across Hamilton County, Shelby County, and Knox County generate hazmat response calls coordinated through TEMA's ESF #10.
• Radiological incidents: Proximity to the Tennessee Valley Authority's nuclear generating stations — Browns Ferry (Athens), Sequoyah (Soddy-Daisy), and Watts Bar (Spring City) — requires TEMA to maintain active radiological emergency preparedness plans in coordination with the NRC and TVA.
• Winter storms: Ice storms affecting East Tennessee mountain counties and Middle Tennessee urban corridors routinely trigger Level 2 activations and mutual aid requests.

Decision boundaries

The triggering thresholds that determine when TEMA escalates from monitoring to active state coordination are structured around resource exhaustion and legal authorization:

• Local-to-state escalation: A county EMA director formally requests state assistance when local resources — personnel, equipment, or funding — are insufficient to manage an incident. This request does not require a gubernatorial declaration but activates TEMA liaison support.
• State declaration vs. federal request: The Governor issues a state emergency declaration before requesting a Presidential disaster declaration. Federal declarations under the Stafford Act require a preliminary damage assessment (PDA) conducted jointly by TEMA, FEMA, and affected county officials to establish that damage thresholds exceed state and local capacity.
• EMAC activation: When Tennessee requires resources from another state, TEMA initiates an EMAC request. When Tennessee provides resources to another state, the sending agency retains command authority over deployed personnel under EMAC Article VI terms.
• Public Assistance vs. Individual Assistance: Following a federal disaster declaration, TEMA administers two distinct FEMA program tracks. Public Assistance funds repair of government infrastructure and eligible nonprofit facilities. Individual Assistance — including FEMA's Individuals and Households Program — provides direct support to disaster survivors and operates through a separate registration and eligibility process managed jointly by FEMA and TEMA.
