EPA Backs NY's PM2.5 Plan: Metro Air Stays Breathable Till 2036
Published Date: 2/12/2026
Proposed Rule
Summary
The EPA is proposing to approve New York’s plan to keep the air clean in the New York metro area for another ten years by controlling tiny pollution particles called PM2.5. This plan affects ten counties and helps make sure the air stays safe to breathe through 2036. People can share their thoughts on this plan until March 16, 2026, but no new costs or big changes are expected.
Analyzed Economic Effects
3 provisions identified: 3 benefits, 0 costs, 0 mixed.
Triggers for Action If PM2.5 Exceeds Limits
The plan requires the State to act if monitors show high PM2.5: if any New York Metropolitan Area monitor’s 98th percentile 24‑hour concentration exceeds 35.5 µg/m3 in a year, NYSDEC will analyze the cause and implement needed control measures; if monitors show exceedances for two consecutive years, NYSDEC will determine additional control measures and implement emissions‑reduction controls by regulation.
NY Metro PM2.5 Plan Keeps Air Safe Through 2036
The EPA is proposing to approve New York State’s limited maintenance plan (submitted October 15, 2024) to keep the 2006 24-hour PM2.5 standard (35 micrograms per cubic meter) met in the New York Metropolitan Area through the second ten‑year maintenance period (through 2036). This action covers ten New York counties (Bronx, Kings, Nassau, New York, Orange, Queens, Richmond, Rockland, Suffolk, and Westchester) and, if approved, would satisfy the Clean Air Act section 175A requirement for the second ten‑year period.
State Must Keep PM2.5 Monitors Running
New York will continue to operate an approved PM2.5 air monitoring network in the NY Metropolitan Area to verify attainment; the submission says there are currently ten monitoring sites and EPA approved New York’s 2023 Annual Monitoring Network plan on January 3, 2024. Continued monitoring is part of the maintenance plan so regulators can track air quality and check that the 35 µg/m3 24‑hour standard is met.

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!
2026-12927, U.S. Ecology Nevada, Inc. High Mercury Subcategory Wastes Land Disposal Restrictions Variance
The EPA is giving U.S. Ecology Nevada a special green light to handle and dispose of high-mercury waste a bit differently than usual. This means mercury waste treated in Pennsylvania can now be safely sent to U.S. Ecology’s Nevada site for disposal under new rules starting July 27, 2026. This change helps protect people and the environment while keeping mercury waste management efficient and cost-effective.
2026-11047, National Emission Standards for Hazardous Air Pollutants From Hazardous Waste Combustors: Residual Risk and Technology Review
