Providing for congressional disapproval under chapter 8 of title 5, United States Code, of the rule submitted by the Environmental Protection Agency relating to "Reconsideration of the National Ambient Air Quality Standards for Particulate Matter".

This joint resolution would nullify a 2024 Environmental Protection Agency (EPA) rule that tightened federal air quality standards for fine particulate matter, commonly known as soot. The EPA rule lowered the allowed annual level of these microscopic particles from 12.0 to 9.0 micrograms per cubic meter to reduce health risks like heart attacks and lung disease. If this resolution becomes law, the stricter standards would be repealed, and the EPA would be prohibited from issuing a substantially similar rule in the future. Supporters of the resolution argue the new standards create unworkable compliance burdens for manufacturers and the energy sector, while opponents emphasize the public health benefits of reduced air pollution.
