Wildfire Air Quality Sensor Expansion Act of 2026

The Wildfire Air Quality Sensor Expansion Act of 2026 directs the Environmental Protection Agency to provide grants and loans to help local air pollution control agencies purchase and operate portable air sensors in rural and remote areas. These low-cost devices are intended to measure smoke pollutants like PM2.5 and ozone in locations where traditional monitoring equipment is scarce, thereby improving the accuracy of air quality data for communities affected by wildfires. To ensure success, the bill also authorizes funding for technical assistance to help agencies install and maintain these sensors, while requiring that the data collected be shared with the EPA to update public air quality maps. The legislation authorizes $10 million annually through 2032 for grants and provides additional unspecified funding for loan programs and technical support, with a specific focus on expanding coverage to Indian tribes and areas lacking existing monitoring infrastructure.
