I. Background and Purpose

    On March 15, 2021 (86 FR 14299), EPA published a Notice of Proposed 
Rulemaking (NPRM) for the State of Connecticut.
    The NPRM proposed approval of Connecticut's SIP revision, which 
replaced two definitions within the previously approved Regulations of 
Connecticut State Agencies (RCSA) Section 22a-174-22e, Control of NOx 
Emissions from Fuel-burning Equipment at Major Stationary Sources of 
NOX. The revision proposed to add to the State's SIP a 
recent amendment to 22a-174-22e concerning the definitions of 
``emergency'' and ``emergency engine,'' which became effective as a 
state requirement on October 8, 2019. Additionally, two compliance 
options were removed from RCSA section 22a-174-22e(g) in light of the 
revised definitions for emergency and emergency engine.
    The formal SIP revision was submitted by Connecticut on December 
20, 2019. The rationale for EPA's proposed action is explained in the 
NPRM and will not be restated here. There were no public comments 
received on the NPRM.

II. Final Action

    EPA is approving Connecticut's December 20, 2019 SIP revision 
request pertaining to its definitions for emergency and emergency 
engine and the removal of compliance options affected by the revised 
definitions.

III. Incorporation by Reference

    In this rule, 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 the 
definitions for emergency and emergency engines and the removal of 
compliance options affected by the revised definitions described in the 
amendments to 40 CFR part 52 set forth below. The EPA has made, and 
will continue to make, these documents generally available through 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).https://www.regulations.gov 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 Clean Air Act, 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, EPA's role is to approve state 
choices, provided that they meet the criteria of the Clean Air Act. 
Accordingly, this proposed 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 proposed action:
     Is not a significant regulatory action subject to review 
by the Office of Management and Budget under Executive Orders12866 (58 
FR 51735, October 4, 1993) and 13563 (76 FR 3821, January 21, 2011);
     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 an economically significant regulatory action based 
on health or safety risks subject to Executive Order 13045 (62 FR 
19885, April 23, 1997);
     Is not a significant regulatory action subject to 
Executive Order 13211 (66 FR 28355, May 22, 2001);
     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; and
     Does not provide EPA with the discretionary authority to 
address, as appropriate, disproportionate human health or environmental 
effects, using practicable and legally permissible methods, under 
Executive Order 12898 (59 FR 7629, February 16, 1994).
    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).
