Approval and Promulgation of Implementation Plans; State of Missouri

AGENCY: Environmental Protection Agency (EPA).
ACTION: Direct final rule.

These revisions make Missouri's rules consistent with Federal regulations and improve the clarity of the rules. EPA's approval of this SIP revision is being done in accordance with the requirements of the Clean Air Act (CAA).
DATES: This direct final rule will be effective November 19, 2012, without further notice, unless EPA receives adverse comment by October 22, 2012.

Outline I. What is being addressed in this document? II. Have the requirements for approval of a SIP revision been met? III. What action is EPA taking? I. What is being addressed in this document?

EPA is approving revisions to the Missouri SIP submitted to EPA on September 21, 2010. EPA has conducted an analysis of the State's amendments and has concluded that these revisions do not adversely affect the stringency of the SIP. Missouri's revisions include amendments to rules 10 CSR 10-6.010Ambient Air Quality Standards,10 CSR 10-6.040Reference Methods,and 10 CSR 10-6.130Controlling Emissions During Episodes of High Air Pollution Potential,as detailed in the technical support document which is part of this docket.

The revisions to 10 CSR 10-6.010Ambient Air Quality Standardsupdate the standards to reflect changes promulgated by EPA through December 21, 2008, for the National Ambient Air Quality Standards (NAAQS) for particulate matter 10 microns or less, particulate matter 2.5 microns or less, ozone and lead. This amendment also corrects the 1971 nitrogen dioxide standard in Missouri. States are not required to adopt ambient air quality standards, but are required to implement the standards adopted by EPA pursuant to section 110 of the CAA. Missouri has adopted standards which are consistent with the EPA standards, and, therefore, this revision to update the state standards is approvable.

The revisions to 10 CSR 10-6.040Reference Methodsupdate the reference methods for measuring ambient air concentrations to determine whether areas are attaining the 2008 ozone and lead NAAQS. Additionally, the amendment incorporates by reference all reference methods found in 40 CFR Part 50 Appendices A-R as well as equivalent methods found in 40 CFR Part 53 into this rule. These appendices describe the methods for measuring ambient concentrations of various pollutants for which NAAQS have been established, and describe how attainment of various NAAQS is determined.

The revisions to 10 CSR 10-6.130Controlling Emissions During Episodes of High Air Pollution Potentialupdate the breakpoint values in Table A of the Air Quality Index (AQI) for eight-hour ozone. The breakpoint values are used to determine whether contingency measures should be implemented during periods of excessive air pollutant concentrations.

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

The state submittal has met the public notice requirements for SIP submissions in accordance with 40 CFR 51.102. The submittal also satisfied the completeness criteria of 40 CFR part 51, appendix V. In addition, as explained above and in more detail in the technical support document which is part of this docket, the revision meets the substantive SIP requirements of the CAA, including section 110 and implementing regulations.

III. What action is EPA taking?

EPA is approving the request to amend the Missouri SIP by approving the State's request to amend 10 CSR 10-6.010Ambient Air Quality Standards,10 CSR 10-6.040Reference Methods,and 10 CSR 10-6.130Controlling Emissions During Episodes of High Air Pollution Potential.Approval of these revisions will ensure consistency between state and Federally-approved rules. EPA has determined that these changes will not relax the SIP or adversely impact air emissions.

We are processing this action as a direct final action because the revisions make routine changes to the existing rules which are noncontroversial. Therefore, we do not anticipate any adverse comments. Please note that if EPA receives adverse comment on part of this rule and if that part can be severed from the remainder of the rule, EPA may adopt as final those parts of the rule that are not the subject of an adverse comment.

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 Order 12866 (58 FR 51735, October 4, 1993);

• Does not impose an information collection burden under the provisions of the Paperwork Reduction Act (44 U.S.C. 3501et 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. 601et 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 Section 12(d) of the National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 note) because application of those requirements would be inconsistent with the CAA; 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).

In addition, this rule does not have tribal implications as specified by Executive Order 13175 (65 FR 67249, November 9, 2000), because the SIP is not approved to apply in Indian countrylocated in the state, and EPA notes that it will not impose substantial direct costs on tribal governments or preempt tribal law.

The Congressional Review Act, 5 U.S.C. 801et seq.,as added by the Small Business Regulatory Enforcement Fairness Act of 1996, generally provides that before a rule may take effect, the agency promulgating the rule must submit a rule report, which includes a copy of the rule, to each House of the Congress and to the Comptroller General of the United States. EPA will submit a report containing this action and other required information to the U.S. Senate, the U.S. House of Representatives, and the Comptroller General of the United States prior to publication of the rule in theFederal Register. A major rule cannot take effect until 60 days after it is published in theFederal Register. This action is not a “major rule” as defined by 5 U.S.C. 804(2).

Under section 307(b)(1) of the CAA, petitions for judicial review of this action must be filed in the United States Court of Appeals for the appropriate circuit by November 19, 2012. Filing a petition for reconsideration by the Administrator of this final rule does not affect the finality of this action for the purposes of judicial review nor does it extend the time within which a petition for judicial review may be filed, and shall not postpone the effectiveness of such rule or action. Parties with objections to this direct final rule are encouraged to file a comment in response to the parallel notice of proposed rulemaking for this action published in the proposed rules section of today'sFederal Register, rather than file an immediate petition for judicial review of this direct final rule, so that EPA can withdraw this direct final rule and address the comment in the proposed rulemaking. This action may not be challenged later in proceedings to enforce its requirements. (See section 307(b)(2).)
