EPA Backs New York's Sulfur Dioxide Neighborly Air Plan
Published Date: 4/10/2026
Proposed Rule
Summary
The EPA is proposing to approve New York’s plan showing it won’t send too much sulfur dioxide pollution to other states, keeping the air cleaner for everyone. This affects New York and its neighbors by helping meet air quality rules from 2010. People can share their thoughts by May 11, 2026, and no new costs are expected from this approval.
Analyzed Economic Effects
3 provisions identified: 3 benefits, 0 costs, 0 mixed.
Large Point Sources Are the Focus
The EPA's review focused on large point sources in New York—facilities reporting more than 100 tons per year (tpy) of SO2—especially those within about 50 kilometers (km) of another State's border. The EPA found these large, near-border sources account for most point-source SO2 and proposes that they are not contributing significantly to out-of-state violations, so no additional federal controls are proposed for those sources.
EPA Proposes Approval of New York SIP
The EPA is proposing to approve New York's plan showing it meets the Clean Air Act 'good neighbor' tests (Prong 1 and Prong 2) for the 2010 1-hour sulfur dioxide (SO2) standard set at 75 parts per billion (ppb). The EPA says this approval would not add new federal requirements or new costs and is based on monitoring and analyses (including 2020 emissions data) focused on sources near state lines.
No Significant Small-Entity Economic Impact
The EPA certified that approving New York's SIP will not have a significant economic impact on a substantial number of small entities, will not impose information collection burdens, and does not create unfunded mandates. The proposed approval therefore is not expected to create new costs or paperwork for small businesses in New York.

The EPA is delaying some rules about the chemical TCE until court decisions are finished. This delay affects certain allowed uses of TCE that had special workplace rules. Businesses using TCE under these exemptions get more time before new restrictions kick in, helping them avoid sudden costs or changes.
2026-07061 — Hazardous and Solid Waste Management System: Disposal of Coal Combustion Residuals From Electric Utilities; Legacy/CCRMU Amendments
The EPA is updating rules on how electric utilities handle coal waste to make cleanup safer and smarter. These changes affect power plants by easing some rules, adding new ways to monitor and close waste sites, and allowing more beneficial reuse of coal waste. Comments are open until June 12, 2026, so utilities and communities can weigh in before the new rules take effect.
2026-06808 — Reconsideration of Standards of Performance for New, Reconstructed, and Modified Sources and Emissions Guidelines for Existing Sources: Oil and Natural Gas Sector Climate Review
The EPA is making some smart tweaks to rules for oil and natural gas companies about how they handle gas flaring and monitoring. These changes fix technical details without changing pollution limits and bring back some important reporting rules accidentally removed last year. The new rules kick in on June 8, 2026, so companies should get ready to follow the updated steps without extra costs.
2026-06275 — Renewable Fuel Standard (RFS) Program: Standards for 2026 and 2027, Partial Waiver of 2025 Cellulosic Biofuel Volume Requirement, and Other Changes
The EPA just set new rules for renewable fuels in 2026 and 2027, including how much biofuel must be used. They’re also easing the 2025 cellulosic biofuel goals because production fell short and removing renewable electricity from the program. These changes affect fuel producers and sellers, kick in mostly mid-2026, and aim to keep cleaner fuels flowing without breaking the bank.
2026-05167 — National Emission Standards for Hazardous Air Pollutants: Ethylene Oxide Emissions Standards for Sterilization Facilities Residual Risk and Technology Review Reconsideration
The EPA is updating rules for sterilization facilities that use ethylene oxide, a chemical that can be harmful if not controlled. They’re rolling back some strict standards from 2024, fixing technical errors, and changing how facilities prove they’re following the rules. If you run or work with these facilities, get ready for new deadlines and ways to stay in compliance by mid-2026.
2026-04646 — Standards of Performance for New Stationary Sources and Emission Guidelines for Existing Sources: Large Municipal Waste Combustors Voluntary Remand Response and Five-Year Review
The EPA is updating pollution rules for big trash-burning plants to cut harmful emissions like lead, mercury, and dioxins. These changes affect both new and existing facilities, tighten limits, remove some loopholes, and improve reporting, all starting May 11, 2026. This update will clean up the air by reducing over 3,200 tons of pollution each year, helping communities breathe easier without breaking the bank.
