40 CFR Part 52

[EPA-R05-OAR-2024-0549; FRL-12784-02-R5]


Air Plan Approval; Ohio; Carmeuse Lime, Inc. SO2

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: The Environmental Protection Agency (EPA) is approving new 
emissions limits for the Carmeuse Lime Maple Grove, Inc. facility into 
the Ohio State Implementation Plan (SIP) for the National Ambient Air 
Quality Standard (NAAQS) for sulfur dioxide (SO2). The Ohio 
Environmental Protection Agency (Ohio EPA) submitted Director's 
Findings and Orders that establish a new emission limit for 
SO2 emissions from two rotary lime kilns at the Carmeuse 
Lime Maple Grove, Inc. facility (hereafter referred to as Carmeuse 
Lime) in Seneca County, Ohio. EPA proposed to approve this action on 
August 7, 2025.

DATES: This final rule is effective on January 12, 2026.

ADDRESSES: EPA has established a docket for this action under Docket ID 
No. EPA-R05-OAR-2024-0549. All documents in the docket are listed on

I. Background Information

    On August 21, 2015 (80 FR 51052), EPA finalized the Data 
Requirements Rule (DRR), which required State air agencies to 
characterize ambient SO2 levels in areas with large sources 
of SO2 emissions to identify sources that may be causing air 
quality problems. Under the DRR (40 CFR 51.1205), for any area where 
modeling of actual SO2 emissions served as a basis for 
designating such area as attainment for the 2010 SO2 NAAQS, 
the State air agency shall submit to EPA an annual SO2 
emissions report of applicable sources by July 1 of each year, 
including an assessment of the cause of any emission increases from the 
previous year and a recommendation regarding the need for additional 
dispersion modeling to determine if an area is still meeting the 2010 
SO2 NAAQS.

[[Page 57375]]

    In August 2023, in preparation for Ohio's 2024 Annual SO Emissions 
Review, Ohio EPA conducted new modeling for Carmeuse Lime due to 
increased emissions at the facility. This new modeling showed 
violations of the SO2 NAAQS near the facility. In response, 
Ohio EPA conducted additional modeling to determine what allowable 
emissions limit to adopt at the Carmeuse Lime facility, that would 
model compliance with the 2010 SO2 NAAQS in the area.
    On November 13, 2024, Ohio EPA submitted a request to EPA to 
incorporate DFFOs that establish a new allowable 30-day rolling average 
SO2 emissions limit of 1,170 pounds per hour (lbs/hr) for 
the combined lime kiln stack shared by two rotary lime kilns. On August 
7, 2025 (90 FR 38093), EPA proposed to approve Ohio EPA's DFFOs to 
ensure continued attainment of the NAAQS. An explanation of the Clean 
Air Act (CAA) requirements, a detailed analysis of the revisions, and 
EPA's reasons for proposing approval were provided in the notice of 
proposed rulemaking (NPRM) and will not be restated here. The public 
comment period for this proposed rule ended on September 8, 2025.

II. EPA's Response to Comments

    During the comment period, EPA received one comment expressing 
general concerns over increased SO2 emissions. The comment 
did not specify a source with increased emissions or the area being 
impacted. In response, EPA clarifies that the addition of the limit in 
the DFFOs being approved in this action establishes a new emission 
limit at the facility and will reduce emissions at Carmeuse Lime. The 
new limit will allow the area around the facility to show modeled 
compliance with the NAAQS and is protective of the environment and 
human health. EPA does not consider the comment to be germane or 
relevant to this action and is therefore, finalizing the action as 
proposed. The comment on the proposed rule is included in the docket 
for this action.

III. Final Action

    EPA is approving Ohio EPA's DFFOs issued to the Carmeuse Lime 
facility submitted on November 13, 2024, into the Ohio 2010 
SO2 NAAQS SIP. The DFFOs establish a new SO2 
emissions limit of 1,170 lbs/hr for the combined lime kiln stack that 
receives and emits SO2 emissions from two rotary kilns, 
ensuring continued attainment of the 2010 SO2 NAAQS.

IV. Incorporation by Reference

    In this rule, EPA is finalizing regulatory text that includes 
incorporation by reference. In accordance with requirements of 1 CFR 
51.5, EPA is finalizing the incorporation by reference of the Ohio 
DFFOs for Carmeuse Lime described in sections I and III of this 
preamble and set forth in the amendments to 40 CFR part 52 below. EPA 
has made, and will continue to make, these documents generally 
available through https://www.regulations.gov, and at the EPA Region 5 
Office (please contact the person identified in the FOR FURTHER 
INFORMATION CONTACT section of this preamble for more information). 
Therefore, these materials have been approved by EPA for inclusion in 
the SIP, have been incorporated by reference by EPA into that plan, are 
fully federally enforceable under sections 110 and 113 of the CAA as of 
the effective date of the final rulemaking of EPA's approval, and will 
be incorporated by reference in the next update to the SIP 
compilation.\1\

V. Statutory and Executive Order Reviews

    Under the CAA, the Administrator is required to approve a SIP 
submission that complies with the provisions of the CAA and applicable 
Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in 
reviewing SIP submissions, EPA's role is to approve State choices, 
provided that they meet the criteria of the CAA. Accordingly, this 
action merely approves State law as meeting Federal requirements and 
does not impose additional requirements beyond those imposed by State 
law. For that reason, this action:
     Is not a significant regulatory action subject to review 
by the Office of Management and Budget under Executive Order 12866 (58 
FR 51735, October 4, 1993);
     Is not subject to Executive Order 14192 (90 FR 9065, 
February 6, 2025) because SIP actions are exempt from review under 
Executive Order 12866;
     Does not impose an information collection burden under the 
provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
     Is certified as not having a significant economic impact 
on a substantial number of small entities under the Regulatory 
Flexibility Act (5 U.S.C. 601 et seq.);
     Does not contain any unfunded mandate or significantly or 
uniquely affect small governments, as described in the Unfunded 
Mandates Reform Act of 1995 (Pub. L. 104-4);
     Does not have federalism implications as specified in 
Executive Order 13132 (64 FR 43255, August 10, 1999);
     Is not subject to Executive Order 13045 (62 FR 19885, 
April 23, 1997) because it approves a State program;
     Is not a significant regulatory action subject to 
Executive Order 13211 (66 FR 28355, May 22, 2001); and
     Is not subject to requirements of section 12(d) of the 
National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 
note) because application of those requirements would be inconsistent 
with the CAA.
    In addition, the SIP is not approved to apply on any Indian 
reservation land or in any other area where EPA or an Indian Tribe has 
demonstrated that a Tribe has jurisdiction. In those areas of Indian 
country, the rule does not have Tribal implications and will not impose 
substantial direct costs on Tribal governments or preempt Tribal law as 
specified by Executive Order 13175 (65 FR 67249, November 9, 2000).
    This rule is exempt from the Congressional Review Act because it is 
a rule of particular applicability.
    Under section 307(b)(1) of the CAA, petitions for judicial review 
of this action must be filed in the United States Court of Appeals for 
the appropriate circuit by February 9, 2026. Filing a petition for 
reconsideration by the Administrator of this final rule does not affect 
the finality of this action for the purposes of judicial review nor 
does it extend the time within which a petition for judicial review may 
be filed, and shall not postpone the effectiveness of such rule or 
action. This action may not be challenged later in proceedings to 
enforce its requirements. (See section 307(b)(2).)
