The Diesel Engine Flexibility Act establishes a ten-year regulatory stability period for diesel engines used in on-road vehicles, non-road equipment, and heavy-duty trucks. During this time, the Environmental Protection Agency is prohibited from issuing new or stricter emission standards beyond the 2007 and 2010 rules for on-road vehicles, or the Tier 4 rules for non-road engines, unless specific exceptions for repairs or fraud enforcement apply. After the decade concludes, any new regulations must include a five-year delay before taking effect and must consider the financial and operational impacts on vehicle owners and manufacturers. The bill also provides legal protection for manufacturers using specific guidance documents to manage engine performance and monitor fluid quality without facing penalties.
The End EPA Abuse Act of 2026 amends the Clean Air Act to limit the Environmental Protection Agency's authority to create new regulations. Specifically, it prohibits the EPA Administrator from issuing rules that restrict the sale or use of internal combustion engine vehicles, force power plants to switch fuel sources, or reduce the reliability of the electric grid. The bill also bars the agency from mandating technologies that are commercially unavailable, too expensive without subsidies, or technically unfeasible due to geographic or infrastructure limitations. Additionally, the law prevents the EPA from expanding its regulatory power beyond what Congress originally intended. These changes directly affect the EPA's ability to enforce environmental standards and impact industries such as automotive manufacturing and energy production.
This bill, titled the Stop Subsidizing Private Jets of 2026, prevents taxpayers from deducting expenses related to private fixed-wing aircraft on their federal income tax returns. It directly affects individuals and businesses that purchase, maintain, or operate personal planes, effectively removing the tax benefit previously available for these costs. The law allows deductions only for specific exceptions, such as aircraft used for property transport, agriculture, firefighting, emergency medical services, or commercial activities like flight instruction and sightseeing tours. These changes will apply to any expenses incurred after December 31, 2025.
The Connected Vehicle Security Act of 2026 restricts the importation, sale, and manufacture of vehicles and related technology from specific countries, including China, Russia, Iran, and North Korea, to address national security concerns. The law defines prohibited items as connected vehicles, their software, and hardware components and sets different effective dates, with vehicle bans starting in 2027 and hardware restrictions beginning in 2030. A government official can grant exceptions for specific items after reviewing security risks and notifying Congress, while the agency must publish annual reports on enforcement actions and compliance.
HR 346, the Preserving Choice in Vehicle Purchases Act, amends the Clean Air Act to clarify that state emissions standards directly or indirectly limiting sales of new internal combustion engine vehicles (ICE) would not qualify for federal EPA waivers. It adds a specific definition to the law, requiring states to avoid restrictions on ICE vehicle sales to maintain waiver eligibility. The bill also mandates the EPA to revoke existing waivers granted between January 2022 and the bill's enactment if those waivers didn't comply with the new definition. This directly affects states with their own vehicle emission standards (like California), the EPA's waiver approval process, and automakers selling vehicles in those states.
HR 2165, the Choice in Automobile Retail Sales Act of 2025, amends the Clean Air Act to prevent the Environmental Protection Agency (EPA) from writing future tailpipe emissions regulations that mandate specific vehicle technologies (like electric or hydrogen systems) or limit the availability of new vehicles based on engine type (e.g., gasoline vs. electric). The bill requires the EPA to update its regulations within 24 months to ensure new rules comply with these restrictions. This directly affects the EPA’s regulatory authority and automakers, as it limits how emissions standards can be structured. The law aims to preserve consumer choice in vehicle types by preventing regulations from favoring one engine technology over others.
This bill codifies existing protections for designated roadless areas within the National Forest System by prohibiting new road construction, road reconstruction, and logging in these areas. It directly affects National Forest lands already identified as "inventoried roadless areas" under the current Roadless Rule, which covers roughly 58 million acres. The key mechanism requires the Secretary of Agriculture to enforce these prohibitions, maintaining current protections without expanding restrictions to other lands or altering existing multiple-use management. The bill does not create new protected areas but legally solidifies the existing regulatory framework to preserve ecological and recreational values.
HR 1137, the "No Kill Switches in Cars Act," repeals Section 24220 of the Infrastructure Investment and Jobs Act (Public Law 117-58), which previously required vehicle manufacturers to implement advanced impaired driving technology. This bill directly affects car manufacturers by removing a mandate to integrate specific safety technology designed to detect driver impairment. The key provision is the repeal itself, eliminating the requirement without creating new obligations or altering existing vehicle safety standards.
The Roadless Area Conservation Act of 2025 would maintain existing protections for designated roadless areas within the National Forest System by prohibiting new road construction, reconstruction, or logging in those areas. It directly affects National Forest lands managed by the U.S. Department of Agriculture’s Forest Service, where the Roadless Rule already restricts such activities. The bill’s key mechanism requires the Secretary of Agriculture to enforce these current restrictions without adding new limitations. This policy change preserves existing protections for watersheds, wildlife habitats, recreation opportunities, and culturally significant sites within these roadless areas.
This bill prohibits the Department of Transportation from providing any federal grants or funds to local governments (including cities, counties, or other state subdivisions) that are classified as "sanctuary cities." A sanctuary city is defined as any local government that restricts sharing immigration status information with federal authorities or refuses to comply with certain immigration detainer requests from Homeland Security. The Secretary of Transportation may grant a limited waiver for specific projects if they certify it serves national interest and notify Congress 15 days in advance. The law directly affects jurisdictions with policies limiting cooperation on immigration enforcement, withholding all DOT funding for transportation projects.
