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.
The Stop Climate Shakedowns Act of 2026 prohibits state and local governments from suing energy companies for damages related to climate change or greenhouse gas emissions. This bill declares that regulating emissions is exclusively a federal responsibility and voids any state laws that hold energy businesses liable for alleged climate harms. Consequently, all pending lawsuits of this nature against energy producers must be dismissed immediately, preventing states from imposing retroactive penalties for past lawful operations. The legislation directly affects companies involved in the production, refinement, and sale of oil, gas, and coal by shielding them from civil liability in both state and federal courts.
This bill nullifies a specific decision made by the Endangered Species Committee regarding oil and gas operations in the Gulf of America. It immediately cancels any exemptions previously granted to these activities under the Endangered Species Act and bars federal agencies from using funds to enforce the canceled order. For a three-year period starting when the bill is enacted, the committee is prohibited from issuing any new exemptions for Gulf oil and gas projects. Consequently, all standard environmental protections required by the Endangered Species Act will continue to apply fully to these activities.
This bill, known as the State Emissions Authority Act of 2026, modifies the Clean Air Act to reduce federal mandates on vehicle inspection and maintenance programs. It primarily affects state governments by removing requirements for them to maintain specific inspection schedules and by limiting the federal government's ability to credit states for emissions reductions achieved through these programs. Additionally, the legislation adjusts rules regarding how states must report their environmental plans and clarifies compliance standards for federal vehicles and installations. By striking several existing sections of the law, the bill effectively shifts more authority over vehicle inspection policies from the federal level to the states.
This bill, titled the "End Polluter Welfare for Enhanced Oil Recovery Act of 2026," eliminates federal tax credits related to enhanced oil recovery (EOR). It directly affects oil and gas companies that utilize or plan to utilize EOR methods. Specifically, the bill strikes Section 43 of the Internal Revenue Code, thereby ending the existing Enhanced Oil Recovery Credit. Furthermore, for new facilities constructed after the bill's enactment, it removes eligibility for the carbon capture tax credit (Section 45Q) when captured carbon oxide is used for enhanced oil recovery. These changes discontinue tax incentives that support specific oil extraction techniques.
HR 2819, the DRIVE Act, prohibits the Federal Motor Carrier Safety Administration from requiring speed limiting devices on trucks weighing over 26,000 pounds operating in interstate commerce. This directly affects commercial truck drivers and carriers that operate large vehicles across state lines. The bill blocks the agency from implementing any rule mandating speed limiters that would cap these trucks' maximum speed. It prevents a potential new federal requirement for trucking companies without altering existing safety standards.
HJRES 57 is a congressional resolution seeking to reject a specific rule issued by the Department of the Interior. It targets the rule titled "Oil and Gas and Sulfur Operations in the Outer Continental Shelf-High Pressure High Temperature Updates" (published in the Federal Register on August 30, 2024). If approved, this resolution would formally disapprove the rule under Chapter 8 of Title 5, U.S. Code, meaning the rule would have no legal effect. This action directly affects the regulatory framework governing oil and gas operations in high-pressure, high-temperature areas on the Outer Continental Shelf. The resolution is procedural and does not create new policy, but rather seeks to nullify an existing regulation.
HR 6213, the Heat Workforce Standards Act of 2025, prohibits the U.S. Department of Labor from finalizing, implementing, or enforcing OSHA's proposed "Heat Injury and Illness Prevention" standard (published August 30, 2024). This bill directly blocks the specific regulatory proposal targeting heat safety in both outdoor and indoor work settings. It does not create new requirements or affect workers; it solely prevents the implementation of the existing OSHA proposal. The bill is procedural, focusing on halting a regulatory action rather than establishing new policy.
HJRES 130 is a congressional disapproval resolution that blocks a specific rule issued by the Bureau of Land Management (BLM) for its Buffalo Field Office. The resolution, enacted December 11, 2025, prevents the "Buffalo Field Office Record of Decision and Approved Resource Management Plan Amendment" from taking effect under federal law. This action directly affects the BLM's management of public lands in the Buffalo area by invalidating the resource management plan amendment. The resolution follows the Congressional Review Act process, which allows Congress to reject agency rules within a specified timeframe.
