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.
