## Summary

**Expand portable air sensor deployment for wildfire smoke monitoring.** This bill would clarify that Clean Air Act section 103 and 105 grant funds can buy and operate portable air sensors and would create competitive grant, loan, and technical assistance programs plus nationally consistent quality-assurance templates. - Families and communities: Residents in rural, remote, and data-scarce areas would get better local smoke readings and public maps, including integration with the AirNow Fire and Smoke Map. - Air pollution control agencies and tribal governments: Could compete for Air Sensor Grants to buy and operate portable sensors and related equipment, with grants authorized at $10 million per year for fiscal 2027–2032. - States and regions: Expands EPA regional sensor loan programs to areas that do not currently participate and funds technical assistance for sensor placement, maintenance, data management, and QA plan development. *Would authorize $10 million per year for grants from 2027 through 2032 and additional funds as necessary, increasing federal spending to support expanded wildfire air monitoring.*

- More portable wildfire sensor grants: benefit, low. This bill would create a competitive EPA grant program to fund portable air sensors for air pollution control agencies. Grants would pay to buy and operate non-regulatory sensors that measure PM2.5, ozone, or other wildfire smoke pollutants. Grant-funded sensors would have to supplement, not replac…
- Technical help and QA templates: benefit, low. This bill would require EPA to provide technical assistance to recipients of the sensor grants and loans and to Clean Air Act section 103 and 105 grant recipients buying sensors. Assistance would cover sensor placement, type selection, maintenance, data management, and quality assurance plan develo…
