SUPPLEMENTARY INFORMATION:

I. Background

On January 18, 2011 (76 FR 2853), EPA published a notice of proposed rulemaking (NPR) for the State of Delaware. The NPR proposed approval, and in the alternative, proposed disapproval of Delaware's infrastructure SIP submittal intended to address significant contribution to nonattainment or interference with maintenance in another state with respect to the 2006 PM_2.5 NAAQS, as required by section 110(a)(2)(D)(i)(I) of the CAA. The formal SIP revision was submitted by the Delaware Department of Natural Resources and Environmental Control (DNREC) on September 16, 2009. As discussed in EPA's January 18, 2011 NPR (76 FR 2853), DNREC supplemented its September 16, 2009 submittal with a technical analysis submitted to EPA for parallel-processing on December 9, 2010. Since the time of EPA's January 18, 2011 NPR, DNREC took the supplemental technical analysis, for which it has requested parallel-processing, through the public notice and hearing procedures required for SIP revisions by section 110 of the CAA. On April 27, 2011, DNREC submitted the technical analysis to EPA as a formal supplement to its September 16, 2009 submittal. The technical analysis submitted on April 27, 2011 is exactly the same as the technical analysis for which DNREC requested parallel-processing on December 9, 2010, and which was included in the rulemaking docket (EPA-R03-OAR-2010-1027) for EPA's January 18, 2011 NPR (76 FR 2853).

This final action addresses only those portions of Delaware's September 16, 2009 submittal that address the 110(a)(2)(D)(i)(I) requirements relating to significant contribution to nonattainment or interference with maintenance in another state with respect to the 2006 PM_2.5 NAAQS. EPA has taken separate action on certain other portions of Delaware's September 16, 2009 submittal. (See Docket ID No. EPA-R03-OAR-2010-0158.)

II. EPA's Evaluation of the SIP Revision

In the January 18, 2011 NPR (76 FR 2853), EPA proposed to approve, and in the alternative, proposed to disapprove Delaware's SIP revision to address significant contribution to nonattainment or interference with maintenance in another state with respect to the 2006 PM_2.5 NAAQS. The NPR explained that if in the course of reviewing and preparing responses to the comments submitted on the proposed “Federal Implementation Plans to Reduce Interstate Transport of Fine Particulate Matter and Ozone” (75 FR 45210, August 2, 2010, also known as the Transport Rule), EPA's additional modeling and the adjustments made to its technical analyses indicate that the State of Delaware should not be subject to or covered by the final Transport Rule, EPA would take final action to approve DNREC's SIP. Alternatively, if in the course of reviewing and preparing responses to the comments submitted on the proposed Transport Rule, EPA's additional modeling and the adjustments made to its technical analyses indicate that the State of Delaware should be subject to and covered by the final Transport Rule, EPA would to take final action to disapprove Delaware's SIP revision for infrastructure element 110(a)(2)(D)(i)(I) for the 2006 PM_2.5 NAAQS. The full explanation and rationale for EPA's proposed action is discussed in the NPR and will not be restated here.

On July 6, 2011, EPA promulgated the Transport Rule, now referred to as the “Cross-State Air Pollution Rule” (CSAPR). EPA's review of the comments submitted on the proposed Transport Rule and the additional modeling and adjustments made to the technical analyses for the final CSAPR indicate that the State of Delaware is meeting its obligations to address the requirements of CAA section 110(a)(2)(D)(i)(I). EPA has, therefore, determined that Delaware is not subject to or covered by the CSAPR. For additional information on the final CSAPR, including the technical support documents and the rationale for EPA's final determination that Delaware does not significantly contribute to any other state's ability to attain or maintain the 2006 PM_2.5 NAAQS, please see Docket ID No. EPA-HQ-OAR-2009-0491 for the Federal Implementation ( printed page 53639) Plan to Reduce Interstate Transport of Fine Particulate Matter and Ozone.

III. Final Action

EPA is approving Delaware's September 16, 2009 SIP revision as supplemented on April 27, 2011. This SIP revision satisfies the CAA infrastructure requirement that each SIP contain adequate provisions prohibiting emissions within the State from contributing significantly to nonattainment in, or interfere with maintenance by, any other state with respect to the 2006 24-hour fine particulate matter (PM_2.5) NAAQS.

IV. Statutory and Executive Order Reviews

A. General Requirements

Under the CAA, the Administrator is required to approve a SIP submission that complies with the provisions of the CAA 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).

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.

B. Submission to Congress and the Comptroller General

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).

C. Petitions for Judicial Review

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 October 28, 2011. 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 approving Delaware's infrastructure SIP to address the requirements of CAA section 110(a)(2)(D)(i)(I) for the 2006 PM_2.5 NAAQS may not challenged later in proceedings to enforce its requirements. (See section 307(b)(2).)

40 CFR part 52 is amended as follows:

1. The authority citation for part 52 continues to read as follows:

Authority: 42 U.S.C. 7401 et seq.
