Fair Air Enforcement Act of 2025

Repeals Section 304 of the Clean Air Act and makes a set of precise conforming edits across the Clean Air Act and one provision of the American Innovation and Manufacturing Act of 2020. The changes remove or redesignate specific sentences, subsections, subparagraphs, and cross-references in the named statutes so the U.S. Code is internally consistent after the repeal.

Implementation will require federal agencies and other stakeholders to update statutory citations, regulatory text, guidance, and administrative references, but the measure does not itself create new programs, funding, or explicit new regulatory requirements.
