## Abstract

The U.S. Environmental Protection Agency (EPA) is taking interim final action on revisions to the National Emission Standards for Hazardous Air Pollutants (NESHAP) for the Coke Oven Batteries (COB) source category and the Coke Ovens: Pushing, Quenching, and Battery Stacks (PQBS) source category by revising certain compliance deadlines for standards finalized in 2024. Specifically, the EPA is amending the compliance deadlines for certain 2024 revisions to the COB and PQBS NESHAPs from July 7, 2025 and January 6, 2026, to July 5, 2027. The EPA seeks comment on this final action and will respond to comments received and revise this final action as appropriate.
