I. Background

On April 12, 2012 (77 FR 21911), EPA proposed to approve a SIP revision submitted by the State of Arizona to address the requirements regarding air pollution emergency episodes in CAA section 110(a)(2)(G). Section 110(a)(2)(G) requires that each SIP provide for authority comparable to that in section 303 of the Act (“Emergency Powers”) and adequate contingency plans to implement such authority. EPA proposed to approve Arizona's SIP revision as meeting the authority and contingency plans for the 1997 8-hour ozone National Ambient Air Quality Standard (NAAQS).

The rationale supporting EPA's action, including the scope of infrastructure SIPs in general, is explained in the Notice of Proposed Rulemaking (NPR) and in the technical support document (TSD) for that action and will not be restated here. The TSD is available online at, Docket ID number EPA-R09-OAR-2012-0244. No public comments were received on the NPR.

II. Final Action

EPA is approving Arizona's SIP revision as meeting the authority and contingency plans for the 1997 8-hour ozone National Ambient Air Quality Standards (NAAQS or standards).

The Arizona Emergency Episode Plan is substantively identical to the CAA section 110(a)(2)(G) rule currently approved into Arizona's SIP (R9-3-219, “Air pollution emergency episodes”), which EPA approved in 1982 (47 FR 42572, September 28, 1982), with one exception which makes it more stringent than the SIP program. We determine that our approval of this submittal would comply with CAA section 110(l), because the SIP revision would not interfere with the ongoing process for ensuring that requirements for reasonable further progress (RFP) and attainment of the NAAQS are met, and the submitted SIP revision is more stringent than the rule previously approved into the SIP. We also determine that our approval of the submittal would comply with CAA section 193, to the extent it applies, because the SIP revision would ensure equivalent or greater emission reductions of ozone precursors compared to the SIP-approved rule. Therefore, EPA is removing the superseded Rule R9-3-219 from the SIP and approving Rule R18-2-220 and the “Procedures for Prevention of Emergency Episodes,” into the SIP.

III. Statutory and Executive Order Reviews

Under the Clean Air Act, 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 Clean Air Act. 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. 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 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 Clean Air Act; and
  • Does not provide EPA with the discretionary authority to address disproportionate human health or environmental effects with practical, appropriate, 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 country located 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. 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 Clean Air Act, petitions for judicial review of this action must be filed in the United States Court of Appeals for the appropriate circuit by December 14, 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. This action may not be challenged later in proceedings to enforce its requirements (see section 307(b)(2)).
