EPA Greenlights Utah's Plan to Zap Tiny Air Pollutants
Published Date: 7/16/2025
Proposed Rule
Summary
The EPA is set to approve Utah’s updated plan to clean up tiny air pollution particles (PM2.5) in Salt Lake City. This plan updates rules for five local facilities to use better pollution controls, helping the air get cleaner faster. Businesses and residents can expect healthier air soon, with changes rolling out after May 2025 and no big new costs announced yet.
Analyzed Economic Effects
2 provisions identified: 1 benefits, 1 costs, 0 mixed.
Cleaner Air for Salt Lake City
The EPA is proposing to approve Utah’s revisions to the State Implementation Plan to address the 2006 24-hour PM2.5 standard in the Salt Lake City nonattainment area. The revisions update rules so five local facilities will use better pollution controls, which the EPA says will help the air get cleaner faster; changes begin rolling out after May 2025.
Updated Controls for Five Facilities
The SIP revisions include updated best available control measures / best available control technology (BACM/BACT) determinations for five facilities in the Salt Lake City nonattainment area, per the State of Utah draft dated May 20, 2025. Those facilities will be subject to revised pollution-control requirements as the changes roll out after May 2025, and the proposal notes no big new costs have been announced.

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!
2026-19071, 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.
2026-18317, 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 giving a thumbs-up to Guam’s updated plan that tracks pollution from sulfur dioxide in the Piti-Cabras area. This helps make sure the air gets cleaner and meets the 2010 air quality rules. People living or working in Guam’s Piti-Cabras area can expect better air quality, with no extra costs or delays announced.

The EPA says the San Joaquin Valley in California has cleaned up its air enough to meet the 1997 fine particle pollution standards by the end of 2024. This means the area is on track to breathe easier, thanks to better air quality from 2022 to 2024. People living and working there can expect healthier air, and the EPA is asking for feedback before making it official.
