HMAG Act of 2025

The Heat Management Assistance Grant Act of 2025 (HMAG Act) would add a new program to the Robert T. Stafford Disaster Relief and Emergency Assistance Act to help states and local governments prevent and respond to extreme heat events. Through a new Section 431, the President (via FEMA) could provide grants, equipment, supplies, and personnel to mitigate and manage extreme heat events, in coordination with the National Oceanic and Atmospheric Administration (NOAA). The bill requires states and localities to submit planning and impact information to qualify for assistance and allows continued hazard mitigation support even if a major disaster is not declared. A 90-day deadline is set to develop a formal threshold for what constitutes an “extreme heat event,” to be determined by FEMA, NOAA, and the CDC. In short, HMAG creates a federal mechanism to fund and coordinate heat-related mitigation and response at the state/local level, with health and weather agencies playing a key role in defining when such events qualify and what costs may be eligible for assistance.
