The bill shifts more authority and faster decision timelines to states and clarifies that prescribed burns can be treated as exceptional events—offering regulatory certainty and improved regional coordination—but at the cost of reduced federal oversight, broader exemptions that could harm local air quality, and compressed EPA rulemaking that may weaken stakeholder review.
State and tribal air regulators gain primary authority to designate exceptional air-monitoring events and the bill explicitly includes 'prescribed fire,' reducing regulatory uncertainty for land managers, fire practitioners, and communities on tribal lands.
The EPA must complete rulemaking on exceptional-event designations faster (proposed rules within 270 days; final within 180 days), accelerating regulatory clarity for states, tribes, and affected stakeholders.
Expanded EPA authority to support multi-state and tribal demonstration projects can improve coordination and consistency in how regional air-quality events are handled.
Rural, tribal, and other local communities could face increased health risks if human-caused events that 'mirror' natural events are treated as exceptional and excluded from regulatory pollutant counts.
Shifting presumptive control to states reduces EPA oversight and could allow divergent or weaker protections in some jurisdictions, potentially worsening air quality for affected populations.
Tight, mandatory EPA deadlines for rulemaking may strain agency resources and shorten time for stakeholder input, increasing the risk of less-vetted or lower-quality regulations.

Rewrites Clean Air Act exceptional-event rules to include prescribed fires, give States primary determinations, and impose deadlines for EPA rule revisions.
Official title: Amend the Clean Air Act to modify the handling of air quality monitoring with respect to prescribed fires, and for other purposes.
Introduced October 23, 2025 by John R. Curtis · Last progress October 23, 2025
Amends the Clean Air Act to change how air-quality monitoring data affected by "exceptional events" are defined and reviewed. The bill explicitly adds "prescribed fire" and certain human-caused events to the exceptional-event definition, makes State determinations controlling unless the EPA Administrator overturns them under new review procedures, and sets firm deadlines for revised rulemaking and intergovernmental collaboration on multistate and tribal demonstrations. The changes shift more initial decisionmaking to States, revise consultation and timing rules for promulgating updated regulations, and preserve prior-day non-exceptional determinations for stationary-source emissions while updating the process for future determinations and demonstrations.
