Latest action (28 Jul 2026): Read twice and referred to the Committee on Environment and Public Works.
What this bill does
The Wildfire Air Quality Sensor Expansion Act of 2026 would amend how certain Clean Air Act grant funds can be used for air quality monitoring. It clarifies that air pollution control agencies receiving existing grants under sections 103 and 105 of the Clean Air Act may use those funds to purchase and operate portable air sensors, which are lower-cost, non-regulatory devices that measure pollutants like PM2.5 and ozone. The bill also creates a new competitive grant program for such sensors, expands existing EPA air sensor loan programs (including the Wildfire Smoke Air Monitoring Response Technology program) into regions, states, and tribal lands not currently served, and directs EPA to provide technical assistance and develop standardized quality assurance templates for these programs.
The bill primarily affects state, local, and tribal air pollution control agencies, particularly those in rural or remote areas with limited air quality monitoring, and communities affected by wildfire smoke. Priority for funding and assistance would go to underserved and wildfire-prone areas. The new sensors are intended to supplement, not replace, existing regulatory air monitors.
The bill authorizes $10 million annually for fiscal years 2027–2032 for the new sensor grant program, plus unspecified funding for the loan program expansion and technical assistance. It was introduced in the Senate on July 28, 2026, and referred to the Committee on Environment and Public Works. It has not yet been voted on, and further committee action would be required before any floor vote.
