This legislative proposal aims to nullify a specific final rule promulgated by the Environmental Protection Agency (EPA). The rule, officially titled "Reconsideration of the National Ambient Air Quality Standards for Particulate Matter" and published in the Federal Register on March 6, 2024, would be entirely invalidated. Should this bill become law, the EPA's reconsideration of the particulate matter air quality standards would lose all legal force and effect , effectively preventing its implementation. The bill's passage would therefore reverse the regulatory changes outlined in that particular EPA action.
