This site displays a prototype of a “Web 2.0” version of the daily Federal Register. It is not an official legal edition of the Federal Register, and does not replace the official print version or the official electronic version on GPO’s govinfo.gov.
The documents posted on this site are XML renditions of published Federal Register documents. Each document posted on the site includes a link to the corresponding official PDF file on govinfo.gov. This prototype edition of the daily Federal Register on FederalRegister.gov will remain an unofficial informational resource until the Administrative Committee of the Federal Register (ACFR) issues a regulation granting it official legal status.

The OFR/GPO partnership is committed to presenting accurate and reliable regulatory information on FederalRegister.gov with the objective of establishing the XML-based Federal Register as an ACFR-sanctioned publication in the future. While every effort has been made to ensure that the material on FederalRegister.gov is accurately displayed, consistent with the official SGML-based PDF version on govinfo.gov, those relying on it for legal research should verify their results against an official edition of the Federal Register. Until the ACFR grants it official status, the XML rendition of the daily Federal Register on FederalRegister.gov does not provide legal notice to the public or judicial notice to the courts.

Environmental Protection Agency (EPA).
Proposed rule; reopening of comment period.
The Environmental Protection Agency (EPA) is reopening the public comment period for 15 days for a proposed rule published August 30, 2024. Reopening the public comment period is focused exclusively on the references to various permit conditions within three Director's Final Findings and Orders (DFFOs) included in the docket that were issued by the Ohio Environmental Protection Agency (Ohio EPA) as those conditions apply to the limits in the DFFOs for Cardinal Power Plant, Ohio Valley Electric Corp.—Kyger Creek, and General James M. Gavin Power Plant.
The comment period for the proposed rule published August 30, 2024, at 89 FR 71124, which ended on September 30, 2024, and was extended until October 15, 2024, at 89 FR 76442, is being reopened. Comments must be received on or before March 17, 2025.
Submit your comments, identified by Docket ID No. EPA-R05-OAR-2021-0544, at https://www.regulations.gov, or via email to langman.michael@epa.gov. Additional instructions to comment can be found in the notice of proposed rulemaking published August 30, 2024 (89 FR 71124).

On August 21, 2024 (89 FR 71124), EPA proposed to approve the Regional Haze State Implementation Plan (SIP) revision submitted by Ohio EPA on July 30, 2021, as satisfying applicable requirements under the Clean Air Act and EPA's Regional Haze Rule for the program's second implementation period. The previous public comment period for the proposed rule ran for 45 days and ended October 15, 2024. In the notice of proposed rulemaking, EPA proposed, among other things, to incorporate by reference three DFFOs issued by Ohio EPA into Ohio's SIP at 40 CFR 52.1870(d). Although the DFFOs were included in the docket at the time when the notice of proposed rulemaking was published on August 30, 2024, the permit conditions referenced within the ( printed page 10877) three DFFOs were not made available in www.regulations.gov until December 23, 2024, due to an oversight. EPA is, therefore, reopening the public comment period for 15 days focused exclusively on the references to the various permit conditions within these three DFFOs as they apply to the limits in the DFFOs.
The referenced permit conditions that were not included in the docket for this rulemaking at the time of the initial public comment period are contained in the permits listed below:
Cardinal Power Plant: title V Permit, Ohio EPA Permit P0133672
Ohio Valley Electric Corp.—Kyger Creek: title V Permit, Ohio EPA Permit P0089199
General James M. Gavin Power Plant: title V Permit, Ohio EPA Permit P0134437
These three permits were publicly available through Ohio EPA's website [1] when the notice of proposed rulemaking was published on August 30, 2024, and EPA has now added them to the docket for this rulemaking.
EPA proposed to incorporate by reference these three DFFOs as well as a DFFO for Miami Fort and Zimmer Power Stations into Ohio's SIP at 40 CFR 52.1870(d) in the notice of proposed rulemaking. EPA is clarifying that EPA is doing so in accordance with requirements of 1 CFR 51.5 and by including regulatory text in the final rule.
As noted in the notice of proposed rulemaking, the DFFOs provide for on-the-way controls. The DFFO for Miami Fort Power Station provides for the permanent shutdown of coal-fired Boilers B015 and B016, and for Zimmer Power Station, provides for the permanent shutdown of coal-fired Boiler B006. The DFFO for Cardinal Power Plant provides for a sulfur dioxide (SO2) emission limit on coal-fired Boilers B001, B002, and B009, which was previously approved by EPA into Ohio's SIP on October 22, 2019 (84 FR 56385), and references conditions of Ohio EPA permit number P0133672 for C.1.d)(1)-(11), C.1.e)(1)-(5), and C.1.f)(1)-(2). The DFFO for Ohio Valley Electric Corp.—Kyger Creek provides for a new nitrogen oxides emission limit on coal-fired Boilers B001, B002, B003, B004, and B005, and references conditions of Ohio permit number P0089199 for C.4.d)(1)-(7), C.4.e)(1)-(6), and C.4.f)(1)-(3). The DFFO for General James M. Gavin Power Plant provides for a new SO2 emission limit on coal-fired Boilers B003 and B004, and references conditions of Ohio permit number P0134437 for C.8.d)(1)-(11), C.8.e)(1)-(4) and, C.8.f)(1)-(2).
