01 · The brief
CRA DisapprovalWhat this resolution actually does

This resolution uses the Congressional Review Act to overturn a rule issued by the Environmental Protection Agency. If both chambers of Congress pass it and the President signs it, the rule is void and has no force. The law also prevents the agency from issuing a substantially similar rule in the future unless Congress enacts new legislation. If the President vetoes it, Congress would need to override the veto to nullify the rule.

Rule targeted

California State Motor Vehicle and Engine Pollution Control Standards; Heavy-Duty Vehicle and Engine Emission Warranty and Maintenance Provisions; Advanced Clean Trucks; Zero Emission Airport Shuttle; Zero-Emission Power Train Certification; Waiver of Preemption; Notice of Decision (88 Fed. Reg. 20688 (April 6, 2023)).

Issuing agency

Environmental Protection Agency (EPA)

Passage rules

This disapproval is a joint resolution under the Congressional Review Act that must be passed by both chambers and presented to the President. In the Senate it is considered under a fast-track process that prevents filibusters and requires only a simple majority, though the President may still veto.

This joint resolution uses the Congressional Review Act to disapprove an EPA rule that granted California a waiver and addressed heavy-duty vehicle emission warranty and maintenance provisions, Advanced Clean Trucks, zero-emission airport shuttles, and related certifications.

If enacted, the resolution would nullify the specified EPA rule (88 Fed.

Reg. 20688 (April 6, 2023)).

Passage30/100

Narrow but highly partisan subject with strong opposition potential; success depends on chamber alignment and executive acceptance.

CredibilityAligned

Relative to its intended legislative type, this bill is a narrowly focused Congressional Review Act disapproval resolution that clearly identifies the target rule and states the singular legal effect (no force or effect). It relies on the CRA framework and requires no complex implementing provisions to achieve its stated purpose.
