Environmental Protection Agency (EPA).


Proposed rule.


The Environmental Protection Agency (EPA) is proposing to approve elements of a State Implementation Plan (SIP) submission from the State of Missouri for the 2012 Annual Fine Particulate Matter (PM2.5) National Ambient Air Quality Standard (NAAQS). States are required to have a SIP that provides for the implementation, maintenance, and enforcement of the NAAQS. Whenever EPA promulgates a new or revised NAAQS, states are required to make a SIP submission to establish that they have, or to add, the provisions necessary to address various requirements to address the new or revised NAAQS. 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. In this action EPA is proposing to approve the interstate transportion obligations of the State's 2012 PM2.5 NAAQS infrastructure SIP submittal.

Throughout this document “we,” “us,” and “our” refer to EPA. This section provides additional information by addressing the following:

I. What is being addressed in this document?

II. Have the requirements for approval of a SIP submission been met?

III. What action is EPA taking?

IV. Incorporation by Reference

V. Statutory and Executive Order Reviews

I. What is being addressed in this document?

EPA is proposing to approve the submittal as meeting the submittal requirement of section 110(a)(1). EPA is proposing to approve certain elements of the infrastructure SIP submission from the State of Missouri received on October 14, 2015. Specifically, EPA is proposing to approve the following elements of section 110(a)(2)(D)(i)(I)—significant contribution to nonattainment (prong 1), and interfering with maintenance of the NAAQs (prong 2). EPA has already addressed elements of 110(a)(2) including: (A) Through (C), (D)(i)(II)—prevention of significant Start Printed Page 25980deterioration of air quality (prong 3), (D)(ii), and (E) through (M) in separate rulemaking (see docket EPA-R07-OAR-2017-0513). EPA intends to act on section 110(a)(2)(D)(i)(II)—protection of visibility (prong 4) in a subsequent rulemaking.

A Technical Support Document (TSD) is included as part of this docket to discuss the details of this action, including analysis of how the SIP meets the applicable 110 requirements for infrastructure SIPs.

II. Have the requirements for approval of a SIP submission been met?

The state's submission has met the public notice requirements for SIP submissions in accordance with 40 CFR 51.102. The state held a public comment period from July 27, 2015, to September 3, 2015. The state received no comments during the public comment period. A public hearing was held on August 27, 2015. The submission satisfied the completeness criteria of 40 CFR part 51, appendix V. As explained in more detail in the TSD, which is part of this docket, the submittal meets the substantive SIP requirements of the CAA, including section 110 and implementing regulations.

III. What action is EPA taking?

EPA is proposing to approve the following elements of October 14, 2015, infrastructure SIP submission from the State of Missouri: Section 110(a)(2)(D)(i)(I)—significant contribution to nonattainment (prong 1), and interfering with maintenance of the NAAQs (prong 2) as applicable to the 2012 Annual PM2.5 NAAQS.

IV. Incorporation by Reference

In this action, EPA is proposing to include in a final EPA rule regulatory text that includes incorporation by reference. In accordance with requirements of 1 CFR 51.5, EPA is proposing to incorporate by reference the Missouri Regulations described in the amendments to 40 CFR part 52 set forth below. EPA has made, and will continue to make, these materials generally available through and at the EPA Region 7 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 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);
  • Is not an Executive 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 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).
