Federal Government News
EPA Partially Approves, Partially Disapproves California’s Heavy-Duty Vehicle Inspection and Maintenance SIP
The U.S. EPA issued a final rule on February 6, 2026, partially approving and partially disapproving California’s Heavy-Duty Inspection and Maintenance Regulation for vehicles over 14,000 pounds. While California's rule is approved for vehicles registered within the state, the partial disapproval rejects enforcement against out-of-state vehicles on Commerce Clause grounds, citing undue burdens on interstate commerce and possible conflicts with federal law. The rule will not trigger sanctions or a federal implementation plan. The EPA's decision spans more than 150 Federal Register pages, addressing extensive public and industry comment, and confirms that approval is limited to in-state vehicles and fleets.
