Public Health Air Quality Act of 2025

Enhanced Health Risk Monitoring: The bill requires fenceline monitoring for stationary sources of hazardous air pollutants that are linked to health threats (Section 3(a)(1)). This helps identify and address emissions that cross property boundaries.

Increased Data Accessibility: The Administrator must publish air quality measurement results on the EPA website in a highly accessible format and a centralized database maintained in multiple languages (Section 3(b)(1)). This allows communities to better understand the air they breathe.

Community Alert Systems: The regulations would allow for an option to sign up for community-wide or source-specific alerts when emissions exceed certain health reference levels (Section 4(f)(3)(A)).

Targeted Monitoring for Vulnerable Areas: NCore monitoring stations are to be prioritized in census tracts with high rates of health conditions like asthma or heart disease, or those with higher poverty levels (Section 5(d)(1)(B)).

Deployment of Local Air Quality Systems: The bill authorizes the deployment of 1,000 air quality systems to provide more localized data to communities (Section 6(a)(1)).

Improved Mapping Tools: The act directs the restoration of the EJSCREEN mapping tool or the creation of a new nationwide geospatial mapping tool to integrate air quality data (Section 8).
