40 CFR Part 52

[EPA-R07-OAR-2021-0378; FRL-10024-86-Region 7]

Air Plan Approval; Iowa; Infrastructure State Implementation Plan 
Requirements for the 2015 Ozone National Ambient Air Quality Standard

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is proposing to 
approve certain elements of a State Implementation Plan (SIP) 
submission from the State of Iowa addressing the applicable 
requirements of section 110 of the Clean Air Act (CAA) for the 2015 
Ozone (O3) National Ambient Air Quality Standard (NAAQS). 
Section 110 requires that each state adopt and submit a SIP revision to 
support the implementation, maintenance, and enforcement of each new or 
revised NAAQS promulgated by the EPA. These SIPs are commonly referred 
to as ``infrastructure'' SIPs. The infrastructure requirements are 
designed to ensure that the structural components of each state's air 
quality management program are adequate to meet the state's 
responsibilities under the CAA.

DATES: Comments must be received on or before July 29, 2021.

I. Written Comments

    Submit your comments, identified by Docket ID No. EPA-R07-OAR-2021-
0378, at https://www.regulations.gov. Once submitted, comments cannot 
be edited or removed from Regulations.gov. The EPA may publish any 
comment received to its public docket. Do not submit electronically any 
information you consider to be Confidential Business Information (CBI) 
or other information whose disclosure is restricted by statute. 
Multimedia submissions (audio, video, etc.) must be accompanied by a 
written comment. The written comment is considered the official comment 
and should include discussion of all points you wish to make. The EPA 
will generally not consider comments or comment contents located 
outside of the primary submission (i.e., on the web, cloud, or other 
file sharing system). For additional submission methods, the full EPA 
public comment policy, information about CBI or multimedia submissions, 
and general guidance on making effective comments, please visit https://www.epa.gov/dockets/commenting-epa-dockets.

II. What is being addressed in this document?

    The EPA is proposing to approve the infrastructure SIP submission 
received from the state on November 30, 2018 in accordance with section 
110(a)(1) of the CAA. Specifically, the EPA is proposing to approve the 
following infrastructure elements of section 110(a)(2) of the CAA: (A) 
through (C), (D)(i)(II)--prevention of significant deterioration of air 
quality (prong 3) and protection of visibility (prong 4), (D)(ii), (E) 
through (H), and (J) through (M). Elements of section 
110(a)(2)(D)(i)(I)--significant contribution to nonattainment (prong 1) 
and interfering with maintenance of the NAAQS (prong 2) will be 
addressed in a separate action.
    Section 110(a)(2)(I) was discussed in the submission, however, the 
EPA does not expect infrastructure SIP submissions to address element 
(I). Section 110(a)(2)(I) requires states to meet the applicable SIP 
requirements of part D of the CAA relating to designated nonattainment 
areas. The specific part D submissions for designated nonattainment 
areas are subject to different submission schedules than those for 
section 110 infrastructure elements. The EPA will act on part D 
attainment plan SIP submissions through a separate rulemaking governed 
by the requirements for nonattainment areas, as described in part D.
    A TSD is included as part of the docket to discuss the details of 
this proposed action, including an analysis of how the SIP meets the 
applicable 110 requirements for infrastructure SIPs.

III. Have the requirements for approval of a SIP revision been met?

    The state submission has met the public notice requirements for SIP 
submissions in accordance with 40 CFR 51.102. The submission also 
satisfied the completeness criteria of 40 CFR part 51, appendix V. The 
state provided a public comment period for this SIP revision from 
September 18, 2018 to October 19, 2018, and received two comments 
related to a request for more stringent ozone requirements and an 
increase in ozone monitors. The state provided an adequate response to 
these comments. In addition, as explained in more detail in the TSD 
which is part of this docket, the revision meets the substantive SIP 
requirements of the CAA, including section 110 and implementing 
regulations.

IV. What action is EPA taking?

    The EPA is proposing to approve elements of the November 30, 2018, 
submission addressing the infrastructure elements for the 2015 
O3 NAAQS. Specifically, the EPA is proposing to approve the 
following infrastructure elements of section 110(a)(2): (A) through(C), 
(D)(i)(II) prong 3 and prong 4, (D)(ii), (E) through (H), (J) through 
(M). The EPA is not acting on the elements of section 
110(a)(2)(D)(i)(I)--prong 1 and prong 2 at this time. Section 
110(a)(2)(I) was discussed in the submission as not being an applicable 
element and the EPA does not expect section 110(a)(2)(I) to be 
addressed in an infrastructure SIP submission. The EPA's analysis of 
the submission is addressed in a TSD which is part of this docket.
    We are processing this as a proposed action because we are 
soliciting comments on this proposed action. Final rulemaking will 
occur after consideration of any comments.

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 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 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 Orders 12866 (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 the National Technology 
Transfer and Advancement Act (NTTA) because this rulemaking does not 
involve technical standards; 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).
    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).
