EPA Nods to California's Antelope Valley Pollution Permit Fixes
Published Date: 3/23/2026
Proposed Rule
Summary
The EPA is proposing to approve updated air pollution permit rules for the Antelope Valley Air Quality Management District in California. These changes fix earlier problems and help control pollution from new or changed factories and businesses. People have until April 22, 2026, to share their thoughts before the EPA makes a final decision.
Analyzed Economic Effects
3 provisions identified: 3 benefits, 0 costs, 0 mixed.
Federal Sanctions Stay Remains
Because EPA is proposing full approval of the amended Rule 1314, the Agency's March 26, 2025 interim final determination that stayed the application of an offset sanction and deferred a highway sanction remains in effect while EPA moves toward final action. This keeps those sanctions from taking effect for now.
Updated Permits for New Polluting Sources
If you operate or plan to build or modify a factory or other stationary source in the Antelope Valley portion of the West Mojave Desert, the EPA is proposing to approve the District's amended New Source Review permitting rule (Rule 1314) adopted July 15, 2025 and submitted October 16, 2025 into the California SIP. If finalized, this will make the amended permitting rule federally enforceable for that local area.
Stronger Controls on New Sources
If you live or work in the Antelope Valley portion of the West Mojave Desert (designated a "Severe" nonattainment area for the 2015 ozone standard), the amended Rule 1314 updates how new or changed stationary sources are reviewed to control ozone precursor emissions. The October 16, 2025 submittal and the July 15, 2025 adoption are intended to address prior EPA-identified deficiencies and to help meet nonattainment permitting requirements.

2026-19071, Partial Repeal of the Carbon Pollution Standards for Fossil Fuel-Fired Electric Generating Units
The EPA is rolling back most of the 2024 rules that limited carbon pollution from fossil fuel power plants. This change affects coal and gas plants by easing some strict limits on emissions and carbon capture technology. The new rules kick in on November 16, 2026, potentially saving money for power plants but raising questions about pollution control.
2026-19072, Rescission of the Greenhouse Gas Findings for Fossil Fuel-Fired Power Plants and Repeal of Regulations for Power Plant Greenhouse Gas Emissions Under Clean Air Act Section 111
The EPA is proposing to cancel all greenhouse gas rules for fossil fuel power plants, saying the law doesn’t let them regulate these emissions for climate reasons. This change affects power plants across the U.S. and could impact future pollution limits and costs. Comments on this proposal are open until November 2, 2026, so now’s the time to speak up!
2026-18317, Updated Definition of “Waters of the United States”
The purpose of this supplemental notice of proposed rulemaking is for the U.S. Environmental Protection Agency (EPA) and the Department of the Army ("the agencies") to supplement and seek additional comment on certain aspects of an earlier proposal, published on November 20, 2025, to revise the regulations defining the scope of waters federally covered under the Clean Water Act in light of the U.S. Supreme Court's 2023 decision in Sackett v. Environmental Protection Agency. As stated in the agencies' November 20, 2025 Notice of Proposed Rulemaking (NPRM), the agencies intend for this rulemaking to provide greater regulatory certainty and increase Clean Water Act program predictability and consistency by clarifying the definition of "waters of the United States." After consideration of the public comments received on the NPRM, the agencies are issuing this notice to supplement the NPRM with additional regulatory options on certain aspects of the proposed rule.
2026-14112, Amendments and Nonconformance Penalties for Model Year 2027 and Later Heavy-Duty Highway Engines and Amendments to Inducement Provisions for SCR-Equipped Diesel Engines
Starting with model year 2027, the EPA is updating rules for big truck engines to make sure they last longer and pollute less. They’re also letting engine makers pay penalties if their engines don’t meet standards, and tightening rules for special pollution-control systems on diesel engines. These changes affect truck and engine makers and kick in soon, with public feedback due by August 29, 2026.
2026-13667, Minor New Source Review Program Air Permitting Public Participation Requirements for State Implementation Plans
The EPA wants to give states more freedom to decide how much public input is needed when approving small air pollution sources or changes. This means local air agencies can tailor public participation to fit their community’s needs while still protecting air quality. If you’re involved in air permits, watch for comment deadlines and possible virtual hearings this summer!
2026-13263, Revisions To Establish the Sixth Unregulated Contaminant Monitoring Rule (UCMR 6) for Public Water Systems
The EPA is rolling out the sixth Unregulated Contaminant Monitoring Rule (UCMR 6) to check for new, sneaky chemicals in public drinking water. Big water systems serving 3,300+ people and some smaller ones will test for 30 different contaminants, including certain PFAS and pesticides, to keep our water safe. Comments and feedback are open until late August 2026, and the EPA will host fun online meetings to chat about the plan!

The EPA is proposing to approve Louisiana’s statement that no old solid waste incinerators exist in certain areas, so no new pollution controls are needed there. This means fewer rules for local businesses and no extra costs for cleanup. People can share their thoughts with the EPA by April 22, 2026.
