II. What is being addressed in this document?

The EPA is proposing to approve the infrastructure SIP submission received from the State of Nebraska on September 24, 2018. Specifically, EPA is proposing to approve the following infrastructure elements of section 110(a)(2): (A) through (C), (D)(i)(I)—prongs 1 and 2, (D)(i)(II)—prong 3, (D)(ii), (E) through (H), and (J) through (M).

A Technical Support Document (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(a)(1) and (2) requirements for infrastructure SIPs. As explained in the TSD, EPA plans to take separate action on the infrastructure elements under section 110(a)(2)(D)(i)(II)—prong 4. The EPA is not taking action on section 110(a)(2)(I)—Nonattainment Area Plan or Plan Revisions Under Part D.

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 August 7, 2018 to September 7, 2018, and at the same time, offered an opportunity for a public hearing. The state received no comments and no requests for a public hearing. The public hearing scheduled for September 11, 2018 was canceled. In addition, as explained in more detail in the TSD, 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 September 24, 2018, infrastructure SIP submission from the State of Nebraska, which address the requirements of CAA sections 110(a)(1) and (2) as applicable to the 2015 O₃ NAAQS. Specifically, the EPA is proposing to approve the following infrastructure elements of 110(a)(2): (A) through (C), (D)(i)(I)—prongs 1 and 2, (D)(i)(II)—prong 3, (D)(ii), (E) through (H), and (J) through (M). As explained in the TSD, the EPA intends to act on section 110(a)(2)(D)(i)(II)—prong 4, in a ( printed page 20319) subsequent rulemaking. The EPA is not taking action on section 110(a)(2)(I)—Nonattainment Area Plan or Plan Revisions under part D.

Based upon review of the state's infrastructure SIP submissions and relevant statutory and regulatory authorities and provisions referenced in those submissions or referenced in Nebraska's SIP, the EPA believes that Nebraska's SIP will meet all applicable required elements of sections 110(a)(1) and (2) (except as otherwise noted) with respect to the 2015 O₃ NAAQS. 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.

VI. 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 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);
• Is not anExecutive Order 13771 (82 FR 9339, February 2, 2017) regulatory action because SIP approvals are exempted under Executive Order 12866.
• 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 inExecutive Order 13132 (64 FR 43255, August 10, 1999);
• Is not an economically significant regulatory action based on health or safety risks subject toExecutive Order 13045 (62 FR 19885, April 23, 1997);
• Is not a significant regulatory action subject toExecutive 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, underExecutive 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).

For the reasons stated in the preamble, EPA proposes to amend 40 CFR part 52 as set forth below:

1. The authority citation for part 52 continues to read as follows:

Authority: 42 U.S.C. 7401 et. seq.

2. In § 52.1420 paragraph (e), the table is amended by adding entry (35) in numerical order to read as follows:

84 FR 20318
