Supplementary Information

Rationale. On December 13, 2024, pursuant to its statutory duty to review and, if appropriate, revise NSPS under section 111(b)(1)(B) of the Clean Air Act, the EPA proposed to strengthen the limits for emissions of nitrogen oxides (NOX) from most new, modified, and reconstructed stationary combustion turbines under new subpart KKKKa of 40 CFR part 60. In addition, the EPA proposed amendments to address specific technical and editorial issues in the current regulations for new, modified, and reconstructed stationary combustion turbines and stationary gas turbines under 40 CFR part 60, subparts KKKK and GG. The EPA received multiple requests for an extension of the initial 90-day comment period to allow stakeholders additional time to review and comment on the proposed rule. This initial comment period ended March 13, 2025. The EPA has decided to reopen the comment period for 21 days. The public comment period will now end on April 15, 2025. Docket. The EPA has established a docket for this rulemaking under Docket ID No. EPA-HQ-OAR-2024-0419. All documents in the docket are listed in https://www.regulations.gov.
