Providing congressional disapproval under chapter 8 of title 5, United States Code, of the rule submitted by the Environmental Protection Agency relating to "California State Motor Vehicle and Engine and Nonroad Engine Pollution Control Standards; The 'Omnibus' Low NOX Regulation; Waiver of Preemption; Notice of Decision".
Became Public Law No: 119-17.
This joint resolution, enacted under the Congressional Review Act, disapproves and nullifies an EPA rule that granted California a waiver to implement its Low NOx motor vehicle, engine, and nonroad engine pollution standards (90 Fed.
Reg. 643, Jan 6, 2025).
The resolution declares that the EPA rule "shall have no force or effect." It removes the specific waiver decision and prevents that rule from taking effect absent new statutory or administrative action.
Narrow and administratively simple but ideologically charged and affecting state authority; success depends on chamber votes and executive approval.
Relative to its intended legislative type, this bill is a concise Congressional Review Act disapproval resolution that precisely identifies the targeted EPA rule and declares it to have no force or effect. It performs the core statutory function with clear specificity but provides minimal supplementary material.
Environmental/health benefits of California's rule vs regulatory burden concerns
Who stands to gain, and who may push back.
- Targeted stakeholdersCould increase NOx emissions compared with California's stricter standards, worsening air quality.
- Targeted stakeholdersMay cause negative public health outcomes, especially respiratory harms in exposed communities.
- StatesUndermines California's established waiver authority under the Clean Air Act, reducing state regulatory flexibility.
Why the argument around this bill splits.
Environmental/health benefits of California's rule vs regulatory burden concerns
Likely strongly opposed.
They would view the resolution as blocking stronger air pollution controls and undermining state authority to protect public health.
They would see it as setting a negative precedent restricting EPA and state climate and air quality leadership.
Mixed/conditional.
Appreciates concerns about regulatory fragmentation and manufacturer burdens, but worries about environmental and public health impacts.
Would favor a compromise: national standards that achieve emissions goals while minimizing inconsistent state rules.
Likely supportive.
Views the resolution as restoring regulatory uniformity, protecting manufacturers from state-specific mandates, and restraining EPA expansion.
Sees blocking the waiver as sensible to avoid burdensome California-imposed rules on other states and industry.
