Wildfire Emissions Prevention Act of 2025

This bill amends the Clean Air Act to change how air quality monitoring data influenced by prescribed fires and exceptional events is handled. It updates definitions, sets deadlines for new regulations, and clarifies processes for state determinations and multi-jurisdictional events.

Sec. 2, Air quality monitoring data influenced by exceptional events and prescribed fires: This section revises Section 319(b) of the Clean Air Act. It adds 'prescribed fires' to the subsection heading and defines a prescribed fire as a planned ignition following laws and regulations to meet specific objectives. It updates the definition of an exceptional event to include prescribed fires and events unlikely to recur unless mirroring a natural event. It requires the Administrator to publish proposed regulatory revisions within 270 days of enactment, after consulting with federal and state agencies, and finalize them within 180 days of the comment period. It also clarifies that air quality data can be excluded if influenced by a prescribed fire, and allows the Administrator to review state determinations for exceptional events or prescribed fires related to exceedances or area designations. Finally, it requires the Administrator to lead multi-jurisdictional exceptional event demonstrations at the request of multiple agencies or tribal authorities.
