ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 52

[EPA-R08-OAR-2025-2070; FRL-13177-02-R8]


Air Plan Approval; Montana; Revisions to Western Sugar 
Stipulation

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is approving 
revisions to the Montana State Implementation Plan (SIP). These 
revisions specifically address sulfur dioxide (SO2) emission 
limits and associated requirements related to the Western Sugar 
Cooperative facility in Billings, Montana. The EPA is taking this 
action pursuant to the Clean Air Act (CAA).

DATES: This rule is effective on June 15, 2026.

ADDRESSES: The EPA has established a docket for this action under 
Docket ID No. EPA-R08-OAR-2025-2070. All documents in the docket are 
listed on the https://www.regulations.gov website. Although listed in

SUPPLEMENTARY INFORMATION: Throughout this document ``we,'' ``us,'' and 
``our'' means the EPA.

I. Background

    The background for this action is discussed in detail in our 
January 23, 2026 proposal (91 FR 2892). In that document we proposed to 
approve Montana's September 25, 2025 revisions to Exhibit A of a 1998 
Stipulation adopting an SO2 control plan for the Billings 
Western Sugar Cooperative facility (hereon ``Western Sugar 
Stipulation'') into the Montana SIP. These revisions included the 
removal of the continuous emission monitor and flow rate monitor 
requirements on the boiler house stack, replacement of the 190-day 
annual campaign limit with a heat input limit, removal of the 
SO2 emission limits and monitoring and reporting 
requirements for the pulp dryer units and the addition of a requirement 
to burn natural gas, and the removal of ``facility modifications'' 
requirements, which have already been completed.
    We received four comments, all from individuals, on our January 23, 
2026 proposed approval. Our responses to the comments are below.

II. Response to Comments

    Comment: All of the commenters expressed support for the EPA's 
proposed action.
    Response: The EPA acknowledges and appreciates the comments in 
support of this rulemaking action.
    Comment: One commenter generally stated that there should be more

[[Page 27210]]

resources allocated to the regulation and monitoring of methane.
    Response: The EPA acknowledges the comment. However, we do not find 
the comment to be sufficiently specific or relevant to the action we 
are taking today to warrant a specific response.

III. Final Action

    The EPA is approving Montana's September 25, 2025 revisions to 
Exhibit A of the Western Sugar Stipulation into the Montana SIP. The 
EPA is taking this action pursuant to the CAA.

IV. Incorporation by Reference

    In this document, the EPA is finalizing regulatory text that 
includes incorporation by reference. In accordance with requirements of 
1 CFR 51.5, the EPA is finalizing the incorporation by reference 
``Western Sugar June 12, 1998 Exhibit A. Emission Limitations and Other 
Conditions,'' as discussed in section I. of this preamble. The EPA has 
made, and will continue to make, these materials generally available 
through https://www.regulations.gov and at the EPA Region 8 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 the EPA for inclusion in the SIP, 
have been incorporated by reference by the 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 the 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 Act and applicable 
Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in 
reviewing SIP submissions, the EPA's role is to approve State choices, 
provided 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 an Executive Order 14192 (90 FR 9065, February 6, 
2025) regulatory action because this action is not significant 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 the 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).
    The Congressional Review Act (CRA), 5 U.S.C. 801 et seq., as added 
by the Small Business Regulatory Enforcement Fairness Act of 1996, 
generally provides that before a rule may take effect, the agency 
promulgating the rule must submit a rule report, which includes a copy 
of the rule, to each House of the Congress and to the Comptroller 
General of the United States. Section 804, however, exempts from 
section 801 the following types of rules: rules of particular 
applicability; rules relating to agency management or personnel; and 
rules of agency organization, procedure, or practice that do not 
substantially affect the rights or obligations of non-agency parties. 5 
U.S.C. 804(3). Because this is a rule of particular applicability, the 
EPA is not required to submit a rule report regarding this action under 
section 801.
    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 July 13, 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)).
