Summary

Disapproves an EPA action that had granted California a waiver to enforce its "Advanced Clean Cars II" motor-vehicle pollution standards and declares that waiver to have no force or effect. The single-section measure targets the EPA Federal Register notice at 90 Fed. Reg. 642 (Jan. 6, 2025).

Key Points

• Disapproves and nullifies the EPA decision granting California a waiver for Advanced Clean Cars II (90 Fed. Reg. 642).
• Makes the identified waiver "no force or effect" — the specific EPA administrative action is voided by statute.
• Targets California's authority to enforce its Advanced Clean Cars II motor vehicle emission/clean-car standards under the waived preemption.
• Affects manufacturers, states that follow California standards, and businesses planning for stricter state vehicle rules.
• Does not appropriate funds, change taxes, or create new federal programs — it is a single-action disapproval of an agency decision.
• Could generate regulatory uncertainty and litigation as agencies, states, and regulated parties respond.
• Does not itself substitute a federal standard; it removes the specific EPA waiver decision only.
