SUPPLEMENTARY INFORMATION:
I. Background
Each State has a SIP containing the control measures and strategies
used to attain and maintain the national ambient air quality standards
(NAAQS). The SIP is extensive, containing such elements as air
pollution control regulations, emission inventories, monitoring
networks, attainment demonstrations, and enforcement mechanisms.
Each State must formally adopt the control measures and strategies
in the SIP after the public has had an opportunity to comment on them
and then submit the proposed SIP revisions to the EPA. Once these
control measures and strategies are approved by EPA, and after notice
and comment, they are incorporated into the federally approved SIP and
are identified in part 52, ``Approval and Promulgation of
Implementation Plans,'' of title 40 of the Code of Federal Regulations
(40 CFR part 52). The full text of the State regulation approved by the
EPA is not reproduced in its entirety in 40 CFR part 52 but is
``incorporated by reference.'' This means that the EPA has approved a
given State regulation or specified changes to the given regulation
with a specific effective date. The public is referred to the location
of the full text version should they want to know which measures are
contained in a given SIP. The information provided allows the EPA and
the public to monitor the extent to which a State implements a SIP to
attain and maintain the NAAQS and to take enforcement action for
violations of the SIP.
The SIP is a living document which the State can revise as
necessary to address the unique air pollution problems in the State.
Therefore, the EPA from time to time must take action on proposed
revisions containing new or revised State regulations. A submission
from a State can revise one or more rules in their entirety, or
portions of rules. The State indicates the changes in the submission
(such as by using redline/strikethrough text) and the EPA then takes
action on the requested changes. The EPA establishes a docket for its
actions using a unique Docket Identification Number, which is listed in
each action. These dockets and the complete submission are available
for viewing on <a href="http://www.regulations.gov">www.regulations.gov</a>.
On May 22, 1997 (62 FR 27968), the EPA revised the procedures for
incorporating by reference, into the Code of Federal Regulations,
materials approved by the EPA into each SIP. These changes revised the
format for the identification of the SIP in 40 CFR part 52, streamlined
the mechanisms for announcing the EPA approval of revisions to a SIP,
and streamlined the mechanisms for the EPA's updating of the IBR
information contained for each SIP in 40 CFR part 52. The revised
procedures also called for the EPA to maintain ``SIP Compilations''
that contain the federally approved regulations and source-specific
permits submitted by each State agency.
The EPA generally updates these SIP Compilations every few years.
Under the revised procedures, the EPA must periodically publish an
informational document in the rules section of the Federal Register
notifying the public that updates have been made to a SIP Compilation
for a particular state. The EPA began applying the revised IBR
procedures to the Idaho SIP on January 25, 2005 (70 FR 3479) and
subsequently published updates to the IBR materials in the Idaho SIP on
December 28, 2012 (77 FR 76417), April 1, 2015 (80 FR 17333), July 24,
2020 (85 FR 44741), November 18, 2024 (89 FR 90592), and June 27, 2025
(90 FR 27470).
II. EPA Action
In this action, the EPA is providing notification of an update to
the materials incorporated by reference into the Idaho SIP as of
January 6, 2026, and identified in 40 CFR 52.670(c) and (d). This
update includes SIP materials submitted by Idaho and approved by the
EPA since the last IBR update. See 90 FR 27470 (June 27, 2025). This
action also corrects a minor typographical error from a previous EPA
approval for the P4 Production LLC, Soda Springs, Idaho facility in
which we inadvertently cited the nonexistent permit condition ``13.33''
instead of the correct citation ``13.23.'' See 90 FR 42821 (September
5, 2025).
III. Good Cause Exemption
The EPA has determined that this action falls under the ``good
cause'' exemption in section 553(b)(3)(B) of the Administrative
Procedure Act (APA) which, upon finding ``good cause,'' authorizes
agencies to dispense with public participation and section 553(d)(3)
which allows an agency to make an action effective immediately (thereby
avoiding the 30-day delayed effective date otherwise provided for in
the APA). This administrative action simply codifies provisions which
are already in effect as a matter of law in Federal and approved state
programs and makes a correction a table in the CFR. Under section 553
of the APA, an agency may find good cause where procedures are
``impracticable, unnecessary, or contrary to the public interest.''
Public comment for this administrative action is ``unnecessary'' and
``contrary to the public interest'' since the codification (and
corrections) only reflect existing law. Immediate notice of this action
in the Federal Register benefits the public by providing the public
notification of the updated Idaho SIP Compilation and notification of
corrections to the Idaho ``Identification of Plan'' portion of the CFR.
Further, pursuant to section 553(d)(3), making this action
[[Page 31933]]
immediately effective benefits the public by immediately updating both
the SIP Compilation and the CFR ``Identification of plan'' section
(which includes table entry corrections).
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 of
regulations promulgated by Idaho previously approved by the EPA and
federally effective before January 6, 2026, contained in 40 CFR
52.670(c) and (d) as described in section I of this preamble. The EPA
has made, and will continue to make, these materials generally
available through <a href="http://www.regulations.gov">www.regulations.gov</a> and at the EPA Region 10 Office
(please contact the person identified in the FOR FURTHER INFORMATION
CONTACT section of this preamble for more information).
V. Statutory and Executive Order Reviews
Under the Clean Air Act, the Administrator is required to approve a
SIP submission that complies with the provisions of the Clean Air 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 that they meet the criteria of the Clean Air Act.
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:
<bullet> 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);
<bullet> Is not an Executive Order 14192 (90 FR 9065, February 6,
2025) regulatory action because this action is not significant under
Executive Order 12866;
<bullet> Does not impose an information collection burden under the
provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
<bullet> 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.);
<bullet> 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);
<bullet> Does not have federalism implications as specified in
Executive Order 13132 (64 FR 43255, August 10, 1999);
<bullet> Is not subject to Executive Order 13045 (62 FR 19885,
April 23, 1997) because it approves a State program;
<bullet> Is not a significant regulatory action subject to
Executive Order 13211 (66 FR 28355, May 22, 2001); and
<bullet> 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 Clean Air Act.
In addition, this action 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).
This action is subject to the Congressional Review Act, and the EPA
will submit a rule report to each House of the Congress and to the
Comptroller General of the United States. This action is not a ``major
rule'' as defined by 5 U.S.C. 804(2).
The EPA also believes that the provisions of section 307(b)(1) of
the Clean Air Act pertaining to petitions for judicial review are not
applicable to this action. This is because prior EPA rulemaking actions
for each individual component of the Idaho SIP Compilation previously
afforded interested parties the opportunity to file a petition for
judicial review in the United States Court of Appeals for the
appropriate circuit within 60 days of such rulemaking action. Thus, the
EPA believes judicial review of this action under section 307(b)(1) is
not available.

\1\ EPA does not have the authority to remove these source-specific requirements in the absence of a
demonstration that their removal would not interfere with attainment or maintenance of the NAAQS, violate any
prevention of significant deterioration increment or result in visibility impairment. Idaho Department of
Environmental Quality may request removal by submitting such a demonstration to EPA as a SIP revision.
\2\ Only a small portion of this facility is located on State lands. The vast majority of the facility is
located in Indian Country. It is EPA's position that unless EPA has explicitly approved a program as applying
in Indian country, State or local regulations or permits are not effective within the boundaries of that
Indian country land for purposes of complying with the CAA. See 68 FR 2217, 2220 (January 16, 2003).
