## Summary

**Expands national monitoring of hazardous air pollutants and fencelines.** This bill would create a national program to require fenceline and stack monitors at priority industrial sites, expand ambient and community sensors, and publish near-real-time data to the public. - Residents and communities: Neighborhoods near industrial facilities would get more local data and public alerts. The bill would deploy at least 1,000 low-cost air quality systems for community clusters. - Industrial sources and operators: About 100 highest-priority facilities would face multi-year fenceline and stack monitoring, extra inspections, and mandatory corrective actions when fenceline levels hit set thresholds. - EPA, science, and enforcement: EPA would have to update and approve new test methods within set deadlines, add 80 NCore multipollutant stations with at least 40 focused on vulnerable populations, and treat community-monitoring rules as enforceable Clean Air Act obligations. *This bill would authorize new federal appropriations including $146 million for Section 3, $50 million for Section 4, $75 million for Section 5, and $6 million for Section 6, and would therefore increase federal spending.*

## Provisions PRIA read

- Better pollution data, methods, and mapping: benefit, medium. If enacted, EPA would be allowed to use hybrid methods that mix monitors, sensors, models, and satellites for technical determinations. EPA must consult with NASA and set rules to use satellite data for design values, with regulations due within 18 months and implementation by January 1, 2028. The…
- Community air sensors and upgrades: benefit, medium. If enacted, EPA would deploy at least 1,000 community air quality systems within 2 years. Each system would cost no more than $5,000 unless EPA explains why a pollutant monitor over $5,000 is required. Systems must be placed in clusters of at least five and at least 500 must measure ozone, PM2.5, N…
- More federal air monitors and repairs: benefit, medium. If enacted, the government would authorize $75,000,000 for fiscal year 2026 to expand and restore national multipollutant monitoring. The EPA would add 80 new NCore stations and must use 5–10% of funds to fix nonoperational monitors in areas not meeting ozone or particle standards. EPA would comple…
- New toxics monitoring and reporting rules: benefit, medium. If enacted, EPA would design and launch a community air toxics emissions and fenceline monitoring program within 18 months after notice and public comment. EPA must publish a list of stationary sources lacking public fenceline monitoring within 270 days and write rules within 2 years that require b…
