[EPA-R05-OAR-2021-0544; FRL-12175-04-R5]
Air Plan Approval; Ohio; Regional Haze Plan for the Second
Implementation Period
AGENCY: Environmental Protection Agency (EPA).
ACTION: Proposed rule; reopening of comment period.
-----------------------------------------------------------------------
SUMMARY: 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.
DATES: 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.
ADDRESSES: Submit your comments, identified by Docket ID No. EPA-R05-
OAR-2021-0544, at https://www.regulations.gov, or via email to
[email protected]. Additional instructions to comment can be
found in the notice of proposed rulemaking published August 30, 2024
(89 FR 71124).
FOR FURTHER INFORMATION CONTACT: Alisa Liu, Air and Radiation Division

SUPPLEMENTARY INFORMATION: 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
[[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.
---------------------------------------------------------------------------
\1\ General James M. Gavin Power Plant: title V Operating
Permit, Ohio EPA Permit P0134437: https://edocpub.epa.ohio.gov/publicportal/ViewDocument.aspx?docid=2661778; Cardinal Power Plant:
title V Operating Permit, Ohio EPA Permit P0133672: https://edocpub.epa.ohio.gov/publicportal/ViewDocument.aspx?docid=2628351;
Ohio Valley Electric Corp.--Kyger Creek: title V Operating Permit,
Ohio EPA Permit P0089199: https://edocpub.epa.ohio.gov/publicportal/ViewDocument.aspx?docid=1777386.
---------------------------------------------------------------------------
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).
