Summary

Repeals 42 U.S.C. § 7604 (the Clean Air Act enforcement provision commonly cited for private "citizen suits") and makes multiple conforming edits across the Clean Air Act and one related statute to remove or update cross‑references and language tied to that provision. The bill deletes or narrows statutory text in several air provisions, renumbers subsections where needed, and removes two citations to the repealed provision in a related statute, producing a net narrowing or elimination of statutory authorities and references that relied on the repealed enforcement provision. These changes can reduce or eliminate private-party enforcement pathways, alter which enforcement or assessment authorities remain in statute, require agencies and courts to adjust to renumbered provisions, and may create transitional legal uncertainty about enforcement options and statutory interpretation.

• Repeals 42 U.S.C. § 7604 (the Clean Air Act provision that authorized certain private civil enforcement actions).
• Makes conforming deletions, cross‑reference removals, and renumberings across multiple Clean Air Act provisions and one related statute to account for that repeal.
• Some deletions go beyond punctuation and remove whole sentences or list items, which substantively narrows or eliminates statutory enforcement or assessment references tied to the repealed provision.
• Removes two explicit citations to the repealed provision in the American Innovation and Manufacturing Act of 2020.
• Renumbering and redrafting of subsections will change statutory structure and could create interpretation or transition issues for agencies and courts.
• Does not create new enforcement mechanisms or appropriate funds; it is textual and structural rather than budgetary.
• Likely reduces private-party enforcement pathways and increases reliance on federal or state enforcement authorities to police violations.
• Could prompt litigation to clarify the scope of remaining enforcement authorities and the effect of deleted language.
