Summary
The EPA has made it easier for businesses and facilities to understand if they’re following air pollution rules under the Clean Air Act. Since May 2019, the EPA has shared clear answers about what counts as new or changed pollution sources and how to monitor them. This helps companies avoid fines and plan ahead, saving time and money while keeping our air cleaner.

EPA posts CAA rulings on public Dashboard
The EPA has posted written applicability determinations, alternative monitoring decisions, and regulatory interpretations for Clean Air Act sections 111, 112, and 129 to a public Dashboard. The Dashboard contains determinations signed after May 2019, was put into use on October 2, 2023, and 62 documents were added to it on June 25, 2025; entries are searchable by facility name, affected subpart, response date, or free-text search.
EPA offers alternative monitoring and interpretations
Under existing regulations the EPA responds to written inquiries and can issue applicability determinations, alternative monitoring decisions, and regulatory interpretations (for example under 40 CFR 60.13(i), 61.14(g), 63.8(b)(1), 63.8(f), and 63.10(f)). Facilities can request EPA permission to use monitoring or recordkeeping that differs from the rule text and can ask whether planned actions count as construction, reconstruction, or modification.

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 FDA just released new guidance to help companies making generic injectable, eye, or ear medicines when they want to change the pH adjusters from the original drug. This makes it clearer how to ask for permission to use different pH adjusters, speeding up approvals and possibly saving money. The guidance is effective starting November 17, 2025, so drug makers should get ready to follow these new rules.
