Dodaro\nComptroller General\nU.S. Government Accountability Office\n441 G Street, N.W.\nWashington, D.C.\u00a0 20548\n\u00a0\nDear Mr. Dodaro:\nWe write to request that the Government Accountability Office (GAO) evaluate the Environmental Protection Agency\u2019s (EPA) air quality monitoring networks for ambient and hazardous air pollutants. These networks play a critical role in protecting public health, especially for children, seniors, and members of other vulnerable populations and disadvantaged communities with chronic and acute health problems such as asthma.\n\u00a0\nThe EPA operates multiple networks to monitor compliance with the Clean Air Act\u2019s National Ambient Air Quality Standards and to track hazardous air pollutants regulated under the act. These networks include the State and Local Air Quality Monitoring Network, the National Air Monitoring Network (which targets areas of high population density with a variety of air pollution sources), Special Purpose Monitoring Stations (used for short-term studies and other purposes), Photochemical Assessment Monitoring Stations (used to measure pollutants that contribute to ground-level ozone, a harmful air pollutant), and the National Air Toxics Trends Stations, among others.\n\u00a0\nThese air quality monitoring networks are increasingly important in implementing and tracking compliance with the Clean Air Act, protecting public health, sharing monitoring data with other agencies, state and local governments, and the public, and informing policy decisions. Given the importance of these networks, we request that GAO respond to the following questions, with an emphasis on data quality, the siting and operation of monitors, trends in public health, the effects of air pollution on vulnerable populations, and shifts in the sources of air pollution, including those associated with vehicles, and industry:\u00a0\u00a0\u00a0\u00a0\u00a0\n\u00a0\n \nWhat strategies does EPA use to deploy and operate its air quality monitoring networks?\nWhat improvements, if any, are needed to guide EPA\u2019s air quality monitoring networks?\nWhat is known about the performance of EPA\u2019s air quality monitoring networks with respect to the number and location of monitors, data quality, and the suitability of data for measuring progress toward air quality standards and other purposes?\u00a0\u00a0\n \n\u00a0\nThank you for your assistance with this request.\u00a0 Should you or members of your GAO staff have any questions about this request, please coordinate with Aaron Goldner (Senator Whitehouse) at (202) 224-2921, Laura Gillam (Senator Carper) at (202) 224-8832, and Olivia Kurtz (Senator Collins) at (202) 224-2523.", 1, "2026-03-30T12:14:52Z", "2026-03-30T12:14:52Z"]], "columns": ["url", "title", "date", "year", "month", "party", "chamber", "state", "member_name", "bioguide_id", "domain", "scraper", "source", "date_source", "text", "has_text", "collected_at", "updated_at"], "primary_keys": ["url"], "primary_key_values": ["https://www.collins.senate.gov/newsroom/collins-whitehouse-carper-request-gao-review-air-quality-monitoring-networks"], "units": {}, "query_ms": 1.322109019383788, "source": "dwillis/congress-press", "source_url": "https://github.com/dwillis/congress-press", "license": "MIT", "license_url": "https://github.com/dwillis/congress-press/blob/main/LICENSE"}
