EPA Proposes Approval of Alabama Air Conformity Rules
Published Date: 7/2/2026
Proposed Rule
Summary
The EPA is proposing to approve Alabama’s updated plan for making sure transportation projects follow clean air rules. This update improves teamwork between agencies, clears up how the public can get involved, and tightens rules to keep the air cleaner. If you want to share your thoughts, you’ve got until August 3, 2026, to speak up—no extra costs or delays expected.
Analyzed Economic Effects
3 provisions identified: 2 benefits, 1 costs, 0 mixed.
Project Sponsors Must Secure Written Controls
If you sponsor a federally funded transportation project in Alabama, the updated MOA and SIP require that written commitments to control measures and mitigation be obtained before a conformity determination and that project sponsors comply with those commitments (see 40 CFR 93.122(a)(4)(ii) and 40 CFR 93.125(c)).
1997 Ozone Conformity Ends in Birmingham Area
For the Birmingham Ozone Area (Jefferson and Shelby Counties), transportation conformity for the 1997 8-hour ozone standard ceases to apply as of June 12, 2026, meaning federally supported transportation activities in that area no longer need conformity determinations under that revoked standard.
No New Federal Burdens for Alabama Small Entities
EPA proposes to approve Alabama's April 7, 2026 SIP revision and states this action does not impose requirements beyond state law, does not create an information collection burden, and is certified as not having a significant economic impact on a substantial number of small entities.

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 EB-5 Reform and Integrity Act of 2022 shakes up the investor visa program by making sure only serious investors who create real jobs get green cards. It affects foreign investors and regional centers, adds new rules to stop fraud, and sets a deadline for public comments by August 31, 2026. This means more trust and transparency in the program, with changes rolling out soon and investments under closer watch.

The FAA wants to let supersonic planes fly over land again by updating old rules that banned them because of loud sonic booms. Thanks to new tech that keeps booms quiet, this change will open the door for faster, cooler flights across the U.S., helping America lead the world in supersonic travel. People and companies interested in supersonic flight should share their thoughts by August 17, 2026.
