Trump signed three CRA resolutions revoking California Clean Air Act waivers; GAO and Senate parliamentarian found CRA inapplicable
On June 12, 2025, President Trump signed H.J. Res. 87, 88, and 89 into law, revoking three EPA Clean Air Act waivers that authorized California to enforce stricter-than-federal vehicle emissions standards under its longstanding § 209(b) authority. Both the Government Accountability Office and the nonpartisan Senate parliamentarian had issued findings that the Congressional Review Act does not legally apply to EPA waiver decisions. The three resolutions' enactment permanently bars EPA from issuing any "substantially similar" waiver, ending California's decades-long independent emissions authority without a statutory basis for the prospective ban.
