This bill, the Public Health Air Quality Act of 2025, directs the Environmental Protection Agency (EPA) to expand air monitoring and public access to air quality data. It requires creation of a Health Emergency Air Toxics Monitoring Network with fenceline and emissions measurement systems at at least 100 high‑priority stationary sources. The bill sets deadlines for EPA to start monitoring (generally within 18 months), keep monitoring for a minimum period (generally 6 years), and make monitoring data publicly available (electronic submission within 1 month and public posting within 7 days). It calls for use and updating of specific EPA test methods (including Method 325A, 325B, 327, and TO‑15A), development of continuous real‑time monitoring for key sites, and routine maintenance and public reporting requirements.
The bill also directs EPA to issue regulations for community air toxics monitoring for specified source categories within 2 years, including required fenceline monitoring, corrective action levels for top hazardous air pollutants, required corrective actions and public reports when levels are exceeded, and enforceability under section 112 of the Clean Air Act.
For ambient monitoring, the bill requires deployment of 80 additional NCore multipollutant stations (using Federal reference or equivalent methods) within 18 months, plus at least 100 additional Federal reference/equivalent monitors in unmonitored or undermonitored areas. It sets siting priorities that focus on vulnerable or overburdened communities and requires public input on siting decisions. The bill calls for procedures to use satellite data to help calculate design values for PM10, PM2.5, ozone, and oxides of nitrogen, with regulations and implementation deadlines.
The bill requires EPA to deploy at least 1,000 low‑cost community air quality systems (clusters of at least 5 per selected area) within 2 years; at least 500 of those must measure ozone, PM2.5, oxides of nitrogen, or sulfur dioxide. If these systems show pollutant levels at or above 98% of an applicable national ambient air quality standard over one year, EPA must install Federal reference or equivalent monitors in that area within 180 days unless EPA waives the requirement with public notice and comment.
The bill also requires EPA to update reporting rules so major and non‑major sources report additional emissions data (including hazardous air pollutants and PFAS) and to restore or create a nationwide mapping and screening tool (similar to EJSCREEN) that integrates data collected under the Act. The bill includes multiple reporting requirements to Congress and the public about staffing and results of monitoring programs.
The bill authorizes specific appropriations (not estimates of total costs beyond those authorizations):
The bill states its purpose is to protect clean air and public health by expanding fenceline and ambient monitoring and by increasing public access to timely air quality information. It emphasizes protecting communities affected by pollution and improving data for health‑based decisions.
