ACTION:

SUMMARY:

The Environmental Protection Agency (EPA) is taking final action to approve a request from the Missouri Department of Natural Resources (MoDNR) to redesignate the Missouri portion of the St. Louis-St. Charles-Farmington, MO-IL fine particulate matter (PM_2.5) unclassifiable area (“St. Louis area” or “area”) to unclassifiable/attainment for the 2012 annual fine particulate matter (PM_2.5) National Ambient Air Quality Standard (NAAQS). The Missouri portion of the St. Louis area comprises of the City of St. Louis and the counties of Franklin, Jefferson, St. Charles, and St. Louis. The EPA now has sufficient data to determine that the St. Louis area is in attainment of the 2012 PM_2.5 NAAQS. Therefore, EPA is approving the state's December 11, 2018 request to redesignate the area to unclassifiable/attainment for the 2012 PM_2.5 NAAQS based upon valid, quality-assured, and certified ambient air monitoring data showing that the PM_2.5 monitors in the area are in compliance with the 2012 PM_2.5 NAAQS. The EPA will address the Illinois portion of the St. Louis area in a separate rulemaking action.

DATES:

This final rule is effective on July 29, 2019.

This final rulemaking takes final action on MoDNR's December 11, 2018, request to change the designation of the Missouri portion of the St. Louis area from unclassifiable to unclassifiable/attainment for the 2012 PM_2.5 NAAQS, based on quality-assured and certified monitoring data for 2015-2017, and approves that the Missouri portion of the St. Louis area has met the requirements for redesignation under section 107(d)(3)(E) of the CAA. The background for this action is discussed in detail in the EPA's proposed rulemaking published in the Federal Register on May 16, 2019 (84 FR 22101).

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 MoDNR held a thirty-day comment period, and a public hearing on October 25, 2018. No oral or written comments were received. The submission satisfied the completeness criteria of 40 CFR part 51, appendix V.

IV. What action is the EPA taking?

The EPA is approving the MoDNR's December 11, 2018, request to redesignate the Missouri portion of the St. Louis area from unclassifiable to unclassifiable/attainment for the 2012 primary annual PM_2.5 NAAQS. This final rulemakng changes the legal designation, found at 40 CFR part 81, of the City of St. Louis and the counties of Franklin, Jefferson, St. Charles, and St. Louis from unclassifiable to unclassifiable/attainment for the 2012 primary annual PM_2.5 NAAQS.

V. Statutory and Executive Order Reviews

Under the CAA, a redesignation of an area to unclassifiable/attainment is an action that affects the status of a geographical area and does not impose any additional regulatory requirements on sources beyond those imposed by state law. A redesignation to unclassifiable/attainment does not create any new requirements. Accordingly, this action merely takes final action to approve to redesignate an area to unclassifiable/attainment and does not impose additional requirements. 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).

This action 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).
