This joint resolution (SJRES 119) seeks congressional disapproval of an Environmental Protection Agency (EPA) rule approving Montana's regional haze plan for the second implementation period under federal air quality standards. If passed, it would nullify the EPA's rule (published in the Federal Register on November 28, 2025), meaning the EPA's approval of Montana's plan would have no legal effect. The bill directly affects Montana's air quality management by blocking federal approval of its haze reduction plan for the second phase. It uses the statutory disapproval process under Title 5 of the U.S. Code to override the EPA's action without changing Montana's underlying air quality plan.
The CLEAR Act (HR 4218) amends the Clean Air Act to streamline state compliance with air quality standards. It extends the review cycle for national air quality standards from five to ten years, requires states to consider economic feasibility alongside technical achievability when developing plans, and gives states up to three years (instead of two) to fix deficiencies before federal intervention. The bill also creates a new exception for wildfire mitigation actions like prescribed fires, allowing states to exclude wildfire-related air quality data from violation determinations. These changes primarily affect states responsible for implementing air quality plans under federal oversight.
This bill amends the Clean Air Act to prevent states from imposing standards that limit the sale or use of new internal combustion engine vehicles. It adds a new requirement that state standards must not directly or indirectly restrict such vehicles, and it prohibits the EPA from considering pre-2025 state standards as valid under existing waivers. The bill also requires the EPA to revoke certain existing waivers granted between January 2022 and the bill's enactment date if those waivers don't comply with the new standard. This directly affects states with their own vehicle emission rules (like California's ZEV program), limiting their ability to regulate internal combustion engine vehicles through EPA-approved standards.
This bill modifies Clean Air Act regulations to expand vehicle fuel options. It allows aftermarket conversions of older vehicles to run on alternative fuels (like natural gas or biodiesel) without being classified as "tampering," provided they meet engineering standards and include required labels. It also creates a new "fuel choice enabling manufacturer" category for companies with 50%+ of their fleet as vehicles designed for non-petroleum fuels (e.g., plug-in electric, flexible fuel, or hydrogen), granting them an 8 MPG bonus in fuel economy calculations. Additionally, the bill prohibits EPA from regulating biomass fuels under the Clean Air Act and adjusts ethanol blending requirements. These changes apply to vehicles manufactured for model year 2026 and later.
The Cold Weather Diesel Reliability Act of 2025 requires the Environmental Protection Agency (EPA) to revise Clean Air Act regulations to address diesel vehicle challenges in extreme cold. It allows diesel vehicle manufacturers to temporarily disable engine power reductions or shutdowns caused by emissions system faults when temperatures are at or below freezing, but only until temperatures rise above freezing. The bill also grants a year-round exemption from diesel exhaust fluid (DEF) system requirements for vehicles primarily operating north of 59°N latitude or in regions with prolonged freezing conditions that make DEF use impractical. This exemption prevents engine derates or shutdowns due to DEF system issues, ensuring critical transportation and emergency services remain functional. The bill does not change overall emissions standards but provides targeted relief for safety and operational needs in cold weather regions.
HR 4117, the Fuel Emissions Freedom Act, would repeal all federal and state fuel emissions standards for motor vehicles. It specifically targets Clean Air Act sections 202 and 209, as well as Corporate Average Fuel Economy (CAFE) standards under 49 U.S.C. 32902-32918, and nullifies all existing regulations under these provisions. The bill prohibits both the federal government and states from establishing or enforcing any future fuel emission standards for vehicles. This would directly affect automobile manufacturers, who would no longer need to comply with emissions regulations, and states, which would lose authority to set their own standards. The bill’s key mechanism is the complete removal of regulatory requirements related to vehicle emissions.
This bill repeals Section 304 of the Clean Air Act, which established civil penalty provisions for violations. It removes the specific penalty framework for air pollution enforcement but does not create new regulations or directly affect any entities. The bill includes minor conforming amendments throughout the Clean Air Act to update references to the repealed section. This is a procedural change with no new policy implementation or direct impact on regulated parties.
This bill amends the Clean Air Act to clarify how air quality data affected by wildfires and planned fire management is handled. It adds "prescribed fire" (a planned fire set for forest management) to the definition of "exceptional events" that states can use to explain temporary air quality spikes. States must now determine if wildfire or prescribed fire emissions qualify as exceptional events, and the EPA must review these state decisions within 180 days. This directly affects state air quality agencies, federal land managers, and wildfire management programs by changing how they report and handle air quality data during fire events.
This bill prohibits the Environmental Protection Agency from reallocating renewable fuel requirements from small refineries that have extended exemptions under the Clean Air Act. It directly affects small refineries with extended exemptions and the companies that would otherwise cover their renewable fuel obligations. The key provision requires the EPA to include gasoline or diesel refined by these exempt small refineries in the total fuel volume calculation for the year, preventing other entities from bearing their share of the renewable fuel mandate. This changes how renewable fuel obligations are calculated to protect consumers from potential cost increases tied to reallocated requirements.
HCONRES 44 is a symbolic resolution recognizing a health and safety emergency for children linked to the Trump administration's climate policies. It claims these policies - unleashing fossil fuel production, blocking renewable energy, and suppressing climate science - disproportionately harm children through increased air pollution, extreme weather, and denied access to climate data. The resolution calls for reversing these policies, restoring the EPA's mission, and ensuring climate action aligns with protecting children's rights. It does not enact new laws or change policy, but serves as a formal congressional statement of concern.
