EPA Agrees Washington D.C. Has No Big Polluters to Regulate
Published Date: 5/29/2026
Rule
Summary
The EPA just gave a thumbs-up to the District of Columbia saying they don’t have any big pollution sources like waste burners, oil and gas plants, or power plants that need special air quality rules. This means no new pollution controls or costs for these facilities in D.C. The rule kicks in on June 29, 2026, keeping things simple and clean for the city.
Analyzed Economic Effects
4 provisions identified: 3 benefits, 1 costs, 0 mixed.
Discovered Facilities Subject to Federal Plan
The EPA notes that if any designated facilities subject to the 111(d)/129 rules are later discovered in the District, those discovered sources would be subject to the applicable Federal plan until the State submits an approvable State plan. This approval is effective June 29, 2026.
No Large Pollution Sources Identified
The EPA approved the District of Columbia's negative declarations saying there are no large municipal waste combustors, crude oil and natural gas facilities, or electric utility generating units subject to the listed Clean Air Act rules in the District. Because of that approval, no new pollution-control requirements or costs under those 111(d)/129 emission guidelines are being imposed in the District of Columbia as of June 29, 2026.
No Significant Small-Business Impact
The EPA certified under the Regulatory Flexibility Act that this approval of the District's negative declarations will not have a significant economic impact on a substantial number of small entities. That certification accompanies the final rule effective June 29, 2026.
No New Reporting or Paperwork Required
The EPA states this approval does not impose any new reporting or recordkeeping requirements and that the Paperwork Reduction Act does not apply. The final rule is effective June 29, 2026.

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!
