II. What is being addressed in this document?

The State revised title 10, division 10 of the code of state regulations, 10 CSR 10-6.062 “Construction Permits by Rule”, which creates a process for exempting certain sources from construction permit obligations by establishing conditions under which these sources can construct and operate without going through the State's formal construction permitting process. Specifically, the revisions to the rule provide crematories and animal incinerators a compliance option and modify restrictions on what these units can incinerate, matches Federal sulfur limits on Number 2 diesel oil, remove “restrictive” words, add definitions specific to the rule, and make other minor edits. 10 CSR 10-6.062 is SIP approved in the Code of Federal Regulations at 40 CFR 52.1320(c). The State submitted its revisions to 10 CSR 10-6.062 to the EPA as a SIP revision on March 7, 2019. In this action, the EPA is proposing to approve these revisions to the Missouri SIP.

The revisions do not impact air quality. The EPA's analysis of the revisions can be found in the technical support document (TSD) included in this docket.

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 public notice of the revisions from August 1, 2018, to October 4, 2018, and held a public hearing on September 27, 2018. The State received and addressed four comments from three sources, which includes EPA. As explained in more detail in the TSD which is part of this docket, the SIP revision submission meets the substantive requirements of the Clean Air Act (CAA), including section 110 and implementing regulations.

IV. What action is EPA taking?

The EPA is proposing to amend the Missouri SIP by approving the State's request to revise 10 CSR 10-6.062, “Construction Permits by Rule.” Approval of these revisions will ensure consistency between State and federally-approved rules. The EPA has determined that these changes will not adversely impact air quality.

The EPA is processing this as a proposed action because we are soliciting comments on the action. Final rulemaking will occur after consideration of any comments.

V. Incorporation by Reference

In this document, the EPA is proposing to include regulatory text in an EPA final rule that includes incorporation by reference. In accordance with requirements of 1 CFR 51.5, the EPA is proposing to incorporate by reference the Missouri Regulations described in the proposed amendments to 40 CFR part 52 set forth below. The EPA has made, and will continue to make, these materials generally available through www.regulations.gov 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).

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 Act and applicable Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in reviewing SIP submissions, the EPA's role is to approve state choices, if 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, the 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 § 52.1320, the table in paragraph (c) is amended by revising the entry “10-6.062” to read as follows:

85 FR 3304
