Summary

Rejects and nullifies an EPA rule that granted California a waiver to implement the "Advanced Clean Cars II" motor vehicle and engine pollution control standards (90 Fed. Reg. 642, Jan. 6, 2025). The resolution declares that the EPA rule has no force or effect, without specifying additional actions, dates, or funding.

Key Points

• Declares the EPA's waiver decision for California's Advanced Clean Cars II rule (90 Fed. Reg. 642) has no force or effect.
• Contains a single, direct disapproval and does not create new regulatory standards or funding.
• Does not specify an effective date or require follow-up agency actions in the statutory text.
• Targets a Clean Air Act waiver decision that would have allowed California-specific vehicle emission standards.
• Likely affects automakers, states that align with California standards, and communities concerned with vehicle emissions.
• Does not itself change federal emissions rules or provide replacement standards.
• Creates legal and regulatory uncertainty for parties who had planned to rely on the waived decision.
• No appropriations, tax changes, or mandates for state spending are included.
