HB346, titled the “Preserving Choice in Vehicle Purchases Act,” would amend the federal Clean Air Act to restrict the Environmental Protection Agency’s ability to approve or maintain state vehicle-emissions standards that directly or indirectly limit the sale or use of new motor vehicles with internal combustion engines. In practical terms, the bill targets state policies that could phase out gasoline- or diesel-powered vehicles, and it would bar EPA from treating post-enactment state amendments as covered by existing Clean Air Act waivers.
The bill also directs EPA to revoke certain waivers granted between January 1, 2022, and the date of enactment if the agency determines those waivers conflict with the new prohibition. Because the measure amends Section 209(b) of the Clean Air Act, it would affect the federal waiver framework that allows California and other states to adopt more stringent vehicle emissions standards than federal baseline rules. The bill’s effect would be to narrow state authority over vehicle sales and emissions-related mandates, especially those associated with electric-vehicle transition policies or internal-combustion-engine restrictions.
Impact
HB346 would change the Clean Air Act by adding a new limitation on state standards that restrict internal combustion engine vehicles and by constraining EPA’s waiver authority. It would likely affect California and any other states relying on California-linked waivers to implement stricter vehicle standards, including policies that encourage or require a shift away from gasoline-powered vehicles. The bill would also require EPA to review and potentially revoke certain waivers issued since January 1, 2022, creating possible legal and regulatory disruption for existing state clean-vehicle programs.
Sentiment
Based on the bill text and the absence of committee debate or recorded votes, the measure appears to be framed by its sponsors as a consumer-choice and anti-mandate bill. The title and structure suggest support from lawmakers opposed to state-level phaseouts of internal combustion engines and supportive of preserving gasoline and diesel vehicle options. No opposing statements are provided in the record here, but the policy is likely to be viewed favorably by critics of electric-vehicle mandates and unfavorably by supporters of state clean-air and decarbonization initiatives.
Contention
The main point of contention is the balance between federal oversight, state autonomy, and environmental regulation. Supporters are likely to argue that states should not be able to effectively ban internal combustion engine vehicles through emissions waivers, while opponents are likely to argue that the bill undermines long-standing Clean Air Act waiver authority and state efforts to reduce pollution and greenhouse gas emissions. The most affected parties would be states with aggressive vehicle electrification policies, automakers subject to those standards, and consumers who may be caught between competing federal and state rules.
