EPA Yanks Coke Oven Polluters' Extra Cleanup Time Abruptly
Published Date: 12/5/2025
Rule
Summary
The EPA is canceling a recent rule that gave coke oven facilities extra time to meet pollution limits. This means these plants must now follow the original deadlines set in 2024 to reduce harmful air pollution. Coke oven operators should get ready to comply on time, avoiding delays that could cost them money or cause trouble.
Analyzed Economic Effects
4 provisions identified: 0 benefits, 4 costs, 0 mixed.
Original Compliance Deadlines Reinstated
If you operate a coke oven manufacturing facility, the EPA cancelled the interim extension and restored the original 2024 compliance dates. Key dates reinstated include July 7, 2025 for many Coke Oven Batteries (COB) requirements and January 5, 2026 for Pushing, Quenching, and Battery Stacks (PQBS) MACT standards; the rescission is effective December 5, 2025. The EPA notes about 11 operating coke facilities are subject to these NESHAP requirements.
Fenceline Monitoring Starts July 7, 2025
If you run a by-product coke oven battery facility, you must begin sampling along the facility property boundary no later than July 7, 2025 and analyze those samples under the specified procedures. This requirement is reinstated by the rescission and is part of Subpart L (Sec. 63.314).
Electronic Reporting Deadlines via CEDRI
You must submit certain compliance certification and other reports electronically through the EPA’s CEDRI portal beginning July 7, 2025 for COB subpart reports (or one year after the subpart template is available, whichever is later) and beginning July 7, 2026 for PQBS subpart reports (or one year after that subpart template is available, whichever is later). Confidential business information must still follow the specified CBI procedures.
Good Combustion Practices Required by Jan 5, 2026
If you operate PQBS-affected batteries, beginning January 5, 2026 you must identify and implement site-specific good combustion practices for each battery. These practices should align with your operating procedures to maintain proper and efficient combustion within battery waste heat flues.

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!
