SUPPLEMENTARY INFORMATION:

I. Background

Upon promulgation of a new or revised NAAQS, sections 110(a)(1) and (2) of the CAA require states to address basic SIP requirements, including emissions inventories, monitoring, and modeling to assure attainment and maintenance for that new NAAQS. Section 110(a) of the CAA generally requires states to make a SIP submission to meet applicable requirements in order to provide for the implementation, maintenance, and enforcement of a new or revised NAAQS within three years following the promulgation of such NAAQS, or within such shorter period as EPA may prescribe. These SIP submissions are commonly referred to as “infrastructure” SIP submissions. Section 110(a) imposes the obligation upon states to make an infrastructure SIP submission to EPA for a new or revised NAAQS, but the contents of that submission may vary depending upon the facts and circumstances. In particular, the data and analytical tools available at the time the state develops and submits the infrastructure SIP for a new or revised NAAQS affect the content of the submission. The contents of such infrastructure SIP submissions may also vary depending upon what provisions the state's existing SIP already contains. In the case of the 2008 8-hour ozone NAAQS, states typically have met the basic program elements required in section 110(a)(2) through earlier SIP submissions in connection with previous ozone NAAQS.

More specifically, section 110(a)(1) provides the procedural and timing requirements for SIPs. Section 110(a)(2) lists specific elements that states must meet for infrastructure SIP requirements related to a newly established or revised NAAQS. As mentioned above, these requirements include basic structural SIP elements such as modeling, monitoring, and emissions inventories that are designed to assure attainment and maintenance of the NAAQS. The requirements of section 110(a)(2) are summarized below and in EPA's September 13, 2013, memorandum entitled “Guidance on Infrastructure State Implementation Plan (SIP) Elements under Clean Air Act Sections 110(a)(1) and 110(a)(2).” ^[1]

• 110(a)(2)(A): Emission Limits and Other Control Measures
• 110(a)(2)(B): Ambient Air Quality Monitoring/Data System

110(a)(2)(C): Programs for Enforcement of Control Measures and ( printed page 11132) for Construction or Modification of Stationary Sources ^[2]

• 110(a)(2)(D)(i)(I) and (II): Interstate Pollution Transport
• 110(a)(2)(D)(ii): Interstate Pollution Abatement and International Air Pollution
• 110(a)(2)(E): Adequate Resources and Authority, Conflict of Interest, and Oversight of Local Governments and Regional Agencies
• 110(a)(2)(F): Stationary Source Monitoring and Reporting
• 110(a)(2)(G): Emergency Powers
• 110(a)(2)(H): SIP revisions

110(a)(2)(I): Plan Revisions for Nonattainment Areas ^[3]

• 110(a)(2)(J): Consultation with Government Officials, Public Notification, and Prevention of Significant Deterioration (PSD) and Visibility Protection
• 110(a)(2)(K): Air Quality Modeling and Submission of Modeling Data
• 110(a)(2)(L): Permitting fees
• 110(a)(2)(M): Consultation and Participation by Affected Local Entities

On November 24, 2014, EPA proposed to approve in part and disapprove in part, the May 29, 2012, and July 26, 2012, 2008 8-hour ozone NAAQS infrastructure SIP submissions with the exception of the PSD permitting requirements for major sources of sections 110(a)(2)(C) and (J), the interstate transport requirements of section 110(a)(2)(D)(i)(I) and (II) (prongs 1 through 4), and the visibility requirements of section 110(a)(2)(J), which EPA will address in a separate action. EPA also proposed to disapprove a portion of Mississippi's infrastructure submission for section 110(a)(2)(E)(ii) pertaining to state board majority requirements respecting significant portion of income. See79 FR 69787. EPA did not receive any comments, adverse or otherwise, on the Agency's November 24, 2014, proposed action. In this rulemaking, EPA is taking final action to approve in part and disapprove in part Mississippi's May 29, 2012, and July 26, 2012, infrastructure submissions as demonstrating that the State meets the applicable requirements of sections 110(a)(1) and (2) of the CAA for the 2008 8-hour ozone NAAQS, as proposed in the Agency's November 24, 2014, rulemaking. EPA will act on portions of Mississippi's submissions not addressed in today's rulemaking in a separate action.

II. Final Action

With the exceptions described below, EPA is taking final action to approve that MDEQ's infrastructure SIP submissions, submitted May 29, 2012, and July 26, 2012, for the 2008 8-hour ozone NAAQS have met the above described infrastructure SIP requirements. EPA is disapproving in part section 110(a)(2)(E)(ii) of Mississippi's infrastructure submissions because the majority of members of boards that approve permits or enforcement orders in Mississippi may still derive a significant portion of income from persons subject to permits or enforcement orders issued by such Mississippi boards, and therefore, its current SIP does not meet the section 128(a)(1) majority requirements respecting significant portion of income. This final approval in part and disapproval in part, however, does not include the PSD permitting requirements for major sources of section 110(a)(2)(C) and (J), the interstate transport requirements of section 110(a)(2)(D)(i)(I) and (II) (prongs 1 through 4), and the visibility requirements of section 110(a)(2)(J), which will be addressed by EPA in a separate action. With the exceptions noted above Mississippi has addressed the elements of the CAA 110(a)(1) and (2) SIP requirements pursuant to section 110 of the CAA to ensure that the 2008 8-hour ozone NAAQS is implemented, enforced, and maintained in Mississippi.

III. 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 underExecutive 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. 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 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, 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 as specified by Executive Order 13175 (65 FR 67249, November 9, 2000), nor will it impose substantial direct costs on tribal governments or preempt tribal law.

The Congressional Review Act, 5 U.S.C. 801 et 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 the Federal Register . A major rule cannot take effect until 60 days after it is published in the Federal 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 May 1, 2015. Filing a petition for reconsideration by the Administrator of this final rule does not affect the ( printed page 11133) 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. This action may not be challenged later in proceedings to enforce its requirements. See section 307(b)(2).

Approval status.

* * * * *

(b) Disapproval. Submittal from the State of Mississippi, through the Mississippi Department of Environmental Quality (MDEQ) on May 29, 2012, and July 26, 2012, to address the Clean Air Act (CAA) section 110(a)(2)(E)(ii) for the 2008 8-hour Ozone National Ambient Air Quality Standards concerning state board majority requirements respecting significant portion of income. EPA is disapproving MDEQ's submittal with respect to section 128(a)(1) because a majority of board members may still derive a significant portion of income from persons subject to permits or enforcement orders issued by the Mississippi Boards, therefore, its current SIP does not meet the section 128(a)(1) majority requirements respecting significant portion of income for the 2008 8-hour Ozone National Ambient Air Quality Standards.
