I. Background
A. Description of a SIP
Each state has a SIP containing, among other things, 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.
B. How EPA Enforces SIPs
Each state must formally adopt the control measures and strategies
to attain and maintain the NAAQS after the public has had an
opportunity to comment on them and then the state must submit the
proposed SIP revisions to EPA. Once these control measures and
strategies are approved by EPA through notice and comment rulemaking,
EPA uses the IBR process to make them part of the federally approved
SIP. IBR is a method of incorporating material into EPA regulations in
the Code of Federal Regulations (CFR) by referencing the original
document(s) without publishing the full text of the material in the
CFR. In this case, the SIP rules are identified in part 52 (Approval
and Promulgation of Implementation Plans), title 40 of the CFR (40 CFR
part 52). These rules are approved by EPA with a specific effective
date, but are not reproduced in their entirety in 40 CFR part 52. This
format allows both EPA and the public to identify which regulations are
contained in a given SIP and to help determine whether the state is
enforcing those regulations. This format also assists EPA and the
public in taking enforcement action, should a state not enforce its
SIP-approved regulations.
C. How the State and EPA Update the SIP
The SIP is periodically revised as necessary to address the unique
air pollution problems in the state. Therefore, EPA must periodically
take action on state SIP submissions containing new and/or revised
regulations and other materials; if approved by EPA, they become part
of the SIP. On May 22, 1997 (62 FR 27968), EPA revised the formatting
procedures of 40 CFR part 52 for incorporating by reference federally-
approved SIP revisions. These procedures include: (1) A revised SIP
document for each state that would use the IBR process under the
provisions of 1 CFR part 51; (2) a revised mechanism for announcing EPA
approval of revisions to an applicable SIP and updating both the
document that has gone through the IBR process and the CFR; and (3) a
revised format of the ``Identification of plan'' sections for each
applicable subpart in 40 CFR part 52 to reflect these revised IBR
procedures. The description of the revised SIP document, IBR
procedures, and ``Identification of plan'' format are discussed in
further detail in the May 22, 1997, Federal Register document.
D. How EPA Compiles the SIPs
The federally-approved regulations and statutes and source-specific
requirements (entirely or portions of) submitted by each state agency
have been compiled by EPA into a ``SIP compilation,'' which is
incorporated by reference. The SIP compilation does not contain the
nonregulatory provisions (entirely or portions of) submitted by each
state agency approved by EPA through previous rulemaking actions in the
Federal Register.
E. How EPA Organizes the SIP Compilation
Each SIP consists of three parts. Part one contains the regulations
and statutes, part two contains the source-specific requirements, and
part three contains nonregulatory provisions. Each state's SIP contains
a table for each of the three parts that identifies each SIP-approved
regulation and statute, source-specific requirement, and nonregulatory
provision. In this action, EPA is publishing the SIP tables that
summarize the applicable SIP requirements for Connecticut and that will
be codified at 40 CFR 52.370. The effective dates in the table indicate
the date of the most recent revision to an approved regulation. EPA
Regional Offices have the primary responsibility for updating the state
SIPs, and the SIP compilations that are incorporated by reference, and
ensuring their accuracy.
F. Where You Can Find a Copy of the SIP Compilation
EPA Region 1 has developed and will maintain the SIP compilation
for Connecticut.
G. The Format of the New Identification of Plan Section
In order to better serve the public, EPA revised the organization
of the section titled ``Identification of plan'' at 40 CFR 52.370 and
included additional information to clarify the enforceable elements of
the SIP. The revised format does not affect Federal enforceability of
the SIP and is consistent with the requirements of section 110(h)(1) of
the Clean Air Act (CAA) concerning comprehensive SIP publication.
The revised ``Identification of plan'' section contains five
subsections:
1. Purpose and scope
2. Incorporation by reference
3. EPA approved regulations
4. EPA approved source specific requirements
5. EPA approved nonregulatory and quasi-regulatory provisions.
H. When a SIP Revision Becomes Part of the SIP and Federally
Enforceable
All new requirements and revisions to the applicable SIP become
federally enforceable as of the effective date of the revisions to
paragraph (c), (d), or (e) of the applicable ``Identification of plan''
section found in each subpart of 40 CFR part 52.
I. The Historical Record of SIP Revision Approvals
To facilitate enforcement of previously approved SIP provisions and
provide a smooth transition to the new
[[Page 5677]]
SIP processing system, EPA will retain the original ``Identification of
plan'' section, previously appearing in the CFR as the first or second
section of part 52 for each state subpart. For Connecticut, the
original Identification of plan section will be moved from Sec. 52.370
to Sec. 52.388.
II. What EPA Is Doing in This Action
We are revising the format of 40 CFR part 52 ``Identification of
plan'' section for Connecticut regarding incorporation by reference, by
adding Sec. 52.370(c), (d), and (e), to be consistent with the format
described above and in 62 FR 27968 (May 22, 1997). We are adding Sec.
52.370(b)(1) to further clarify that all SIP revisions listed in Sec.
52.370(c) and (d), regardless of inclusion in the most recent ``update
to the SIP compilation,'' are federally enforceable under sections 110
and 113 of the CAA as of the effective date of the final rulemaking in
which EPA approved the SIP revision. We are adding Sec. 52.370(b)(2)
to certify that the materials provided by EPA at the addresses in
paragraph (b)(3) are an exact duplicate of the official state rules/
regulations. We are adding Sec. 52.370(b)(3) to update address and
contact information.
This action constitutes a recordkeeping and organizational exercise
to ensure that all revisions to the state programs that have occurred
are accurately reflected in 40 CFR part 52. SIP revisions are
controlled by EPA regulations at 40 CFR part 51.
EPA has determined that this action falls under the ``good cause''
exemption in sections 553(b)(4)(B) and 553(d)(3) of the Administrative
Procedure Act (APA), which, upon finding ``good cause,'' authorizes
agencies to dispense with public participation and allows an agency to
make a rule effective immediately, thereby avoiding the 30-day delayed
effective date otherwise provided for in the APA. This action simply
reformats and codifies provisions which are already in effect as a
matter of law in Federal and approved state programs. Under section
553(b)(4)(B) of the APA, an agency may find good cause where notice and
public procedure are ``impractical, unnecessary, or contrary to the
public interest.'' Public comment is unnecessary for this action
because EPA is merely reformatting and codifying existing law.
Immediate notice in the CFR benefits the public by removing outdated
citations and making the IBR format clearer and more user-friendly.
III. 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 regulations
promulgated by Connecticut, previously approved by EPA and federally
effective before August 25, 2025, contained in 40 CFR 52.370(c) and
(d), described in section II. of this preamble. EPA has made, and will
continue to make, these documents generally available through
<a href="http://www.regulations.gov">www.regulations.gov</a> and at the EPA Region 1 office (please contact the
person identified in the FOR FURTHER INFORMATION CONTACT section of
this preamble for more information).
IV. 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 addresses administrative requirements related to
previously approved state law found to meet Federal requirements and
does not impose additional requirements beyond those previously 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 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 is an administrative action related to state
program approval;
<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 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 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).
EPA has also determined that the provisions of section 307(b)(1) of
the CAA pertaining to petitions for judicial review are not applicable
to this action. Prior EPA rulemaking actions for each individual
component of the Connecticut SIP compilation 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, EPA believes judicial review of
this action under section 307(b)(1) is not available.
