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 Modernizing Aeronautical Standards Act requires NASA to conduct a study on updating current aviation standards to account for changing atmospheric conditions. This study will analyze how variations in temperature and other weather factors over the past 50 years impact the performance, maintenance costs, and operational limits of the top ten most-used commercial aircraft at the nation's busiest airports. The report will also assess necessary infrastructure investments and design modifications for future planes, with results to be shared with Congress within 18 months.
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 redesignates the existing National Parks and Public Land Legacy Restoration Fund as the America's Legacy Restoration Fund to address deferred maintenance on federal lands. It directs revenue from recreation fees and a portion of energy development income into the fund, which must be used primarily for repairing critical infrastructure like roads, trails, and buildings managed by agencies such as the National Park Service and the Forest Service. The legislation establishes strict rules requiring that most funds go toward non-transportation projects, mandates transparency through public dashboards tracking project status, and sets aside a small percentage for matching private donations. Additionally, the bill increases entrance fees for foreign visitors to ensure they contribute to the fund, while prohibiting the use of these specific funds for land acquisition or employee bonuses.
The Southeastern Rail Technologies Mapping Act of 2026 directs the Federal Railroad Administration to study how to improve rail performance and integrate new power technologies in the southeastern United States. This study will examine rail segments between Florida and Washington, DC to identify areas suitable for electrification or battery and fuel cell systems while noting any implementation challenges. If certain segments are found unsuitable for these technologies, the report must explain the reasoning and suggest specific infrastructure updates with estimated costs to make them viable. The Administrator is required to submit the findings of this study to Congress within 18 months of the bill's enactment.
The Improving Travel for Military Members Act directs the Transportation Security Administration to create a pilot program that allows active-duty military personnel and their families to use expedited security lanes at select airports. This initiative requires that all participants still undergo standard vetting checks and mandates that security staff verify eligibility before allowing access to these faster lanes. The program will prioritize airports located near military bases with large numbers of stationed troops and must operate for a period of three years. Additionally, the TSA Administrator is required to provide a briefing to Congress on the program's progress within nine months of its launch.
The American Electric Rail Mapping Act of 2026 directs the Federal Railroad Administration to conduct a study on the feasibility of electrifying passenger and freight rail lines across the United States. This study will identify existing and planned rail corridors, determine how current systems are powered, and assess which segments could adopt clean rail technologies. The Administrator must consult with railroad operators, state and local governments, and other relevant entities while using existing resources to minimize costs. The agency is required to submit an initial progress report to Congress within one year of enactment, followed by a final report on the study's results a year later.
The Rail Motive Power Source Integration Act of 2026 directs the Federal Railroad Administration to launch a pilot program exploring how trains can switch between different power sources like batteries, electricity, hydrogen, and diesel. The bill requires the agency to research these technologies, design rail cars that allow for easy power source changes, and test these designs through demonstration projects. Additionally, the Administrator must study locations where trains currently need to change power sources due to limitations and report the findings to Congress within one year of the law's enactment.
The Complete America's Great Trails Act creates a new federal tax credit to encourage private landowners to donate land or conservation easements that include National Scenic Trails. This provision allows taxpayers to claim a credit equal to the fair market value of their donation, provided the land covers a trail corridor of at least 50 feet on each side, while also preventing them from taking a separate tax deduction for the same gift. The bill permits continued recreational or agricultural use of the donated land as long as it does not harm conservation goals. Additionally, the legislation requires the Secretary of the Interior to study the credit's effectiveness and report to Congress on whether it should be made refundable or transferable within four years.
The American High-Speed Rail Act expands federal funding and streamlines regulations to support the development of high-speed and higher-speed rail projects across the United States. It authorizes billions of dollars in grants for corridor planning, technology improvements, and construction, while allowing the federal government to cover up to 100% of project costs under specific conditions. The bill also introduces new provisions to facilitate land acquisition, prioritize border projects, and extend labor protections to workers involved in federally funded rail infrastructure. Additionally, the legislation defines higher-speed rail as trains traveling between 110 and 186 miles per hour and includes tax incentives for rail carriers that sell or lease property to support these projects.
