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, including such elements as air pollution
control regulations, source-specific permit requirements, emission
inventories, monitoring networks, attainment demonstrations, and
enforcement mechanisms.
Each State must formally adopt air pollution control measures and
strategies and submit the associated regulatory materials to the EPA
for approval into the SIP. Upon EPA approval, regulatory materials are
incorporated into the federally approved SIP in title 40 of part 52,
``Approval and Promulgation of Implementation Plans,'' of the Code of
Federal Regulations (40 CFR part 52). The full text of a State
regulation approved by the EPA is not reproduced in its entirety in 40
CFR part 52, rather, it is ``incorporated by reference (IBR).'' This
means that the EPA has approved a given State regulation, or changes to
that regulation, based on a specific effective date. The public is
referred to the location of the full text version of the regulation.
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.
Each SIP is a living document revised as necessary by a State to
address Clean Air Act requirements and the unique air

[[Page 27471]]

pollution problems in the State. Therefore, the EPA must routinely take
action on SIP revisions that include new or revised State regulatory
materials. A State may revise one or more regulations in their
entirety, or portions of regulations. The State indicates the submitted
changes by using redline/strikethrough text, for example, and the EPA
takes action on the changes. The EPA establishes a docket for each
action using a unique Docket Identification Number and places the
submitted regulations and other materials supporting the action in the
docket. Dockets are available for viewing on <a href="http://www.regulations.gov">www.regulations.gov</a>.
On May 22, 1997 (62 FR 27968), the EPA, in coordination with the
Office of the Federal Register, revised the procedures used to
incorporate State regulatory materials by reference into the CFR for
each SIP. These changes revised the format for the identification of
the SIP in 40 CFR part 52, streamlined the mechanism for announcing EPA
approval of revisions to a SIP, and consolidated the process for EPA
updates to the IBR materials in 40 CFR part 52. The revised IBR
procedures called for the EPA to maintain ``SIP Compilations'' with the
full text of the federally approved State regulatory materials.
The EPA generally updates each SIP Compilation every few years, or
more frequently when large amounts of regulatory materials have been
incorporated by reference. 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 specific SIP Compilation. 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), and November 18, 2024 (89 FR 90592).

C. Corrections and Clarifications to CFR Tables

The EPA is notifying the public of corrections and clarifications
to the CFR tables that identify the IBR materials in the Idaho SIP. The
EPA has made minor wording changes to the ``Explanations'' column of
the tables for consistency. We have also removed the text from the
``Explanations'' column for entries ``600'' through ``616'' because the
text referred to a prior EPA approval date of July 11, 2005 that was
then removed in response to a court remand. Entries ``600'' through
``616'' have been revised and approved numerous times since 2005 and
therefore the text referencing the prior July 11, 2005, EPA approval
date is obsolete.

II. EPA Action

In this action, the EPA is notifying the public of an update to the
regulatory materials incorporated by reference into the Idaho SIP and
federally effective as of January 6, 2025. This update includes
regulatory materials submitted by Idaho and approved by the EPA since
the last IBR update. See 89 FR 90592 (November 18, 2024).

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, makes corrections and clarifying changes to the tables in the
CFR, and makes ministerial changes to the prefatory heading to the
tables 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 immediately effective benefits
the public by immediately updating both the SIP Compilation and the CFR
``Identification of plan'' section (which includes table entry
corrections and clarifications).

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, 2025 as described in section I.
of this document. 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 (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, The 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:
<bullet> Is not a significant regulatory action subject to review
by the Office of Management and Budget under

[[Page 27475]]

Executive Order 12866 (58 FR 51735, October 4, 1993);
<bullet> Is not subject to Executive Order 14192 (90 FR 9065,
February 6, 2025) because SIP actions are exempt from review 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 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 it 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, 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. The EPA will submit a report containing this action and
other required information to the U.S. Senate, the U.S. House of
Representatives, and the Comptroller General of the United States prior
to publication of the rule in the Federal Register. A major rule cannot
take effect until 60 days after it is published in the Federal
Register. 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 CAA 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).

(e) EPA approved nonregulatory provisions and quasi-regulatory
measures.
