This action finalizes amendments to the national emission standards for hazardous air pollutants (NESHAP) for the Coal- and Oil-Fired Electric Utility Steam Generating Units (EGUs) source category. These final amendments are the result of the EPA's review of the 2020 Residual Risk and Technology Review (RTR). The changes, which were proposed under the technology review in April 2023, include amending the filterable particulate matter (fPM) surrogate emission standard for non-mercury metal hazardous air pollutants (HAP) for existing coal-fired EGUs, the fPM emission standard compliance demonstration requirements, and the mercury (Hg) emission standard for lignite-fired EGUs. Additionally, the EPA is finalizing a change to the definition of “startup.” The EPA did not propose, and is not finalizing, any changes to the 2020 Residual Risk Review.This final rule is effective on 8 July 2024. The incorporation by reference of certain material listed in the rule was approved by the Director of the Federal Register as of 16 April 2012.Title 40 Code of Federal Regulations (CFR) Part 63This final rule and the proposed rule notified as G/TBT/N/USA/1837/Rev.1 are identified by Docket Number EPA-HQ-OAR-2018-0794. The Docket Folder is available from Regulations.gov at https://www.regulations.gov/docket/EPA-HQ-OAR-2018-0794/document and provides access to primary and supporting documents as well as comments received.
