SUPPLEMENTARY INFORMATION:

Throughout this document, whenever “we,” “us,” or “our” is used, we mean EPA. On April 1, 2010, Delaware submitted a revision to its SIP for changes noted in Regulation 1125, Requirements for Preconstruction Review, Prevention of Significant Deterioration (PSD) found in section 3.0 of Regulation 1125 (Regulation 1125, section 3.0).

I. Background

This SIP revision governs the permits for constructing and significantly modifying major stationary sources of air pollutants in PSD areas located in Delaware. This regulatory revision was made effective as a legislative rule in Delaware on April 11, 2010. This regulatory revision became effective as a legislative rule in the State on April 11, 2010 and can be found in Regulation 1125, section 3.0. This SIP revision, as proposed, will only replace the current regulations found in Regulation 1125, section 3.0 which establish NOX as a precursor to ozone, but will keep intact the formally approved Delaware SIP increments for NOX found in the Federal Register action for Delaware dated July 27, 1993 (58 FR 40065).

Delaware's proposed SIP submission addresses changes needed in the part C PSD permit program. This SIP submission also corrects deficiencies identified by EPA in the March 27, 2008 Federal Register action entitled, “Completeness Findings for Section 110(a) State Implementation Plans for the 8-hour Ozone National Ambient Air Quality Standards (1997 Ozone NAAQS)” (73 FR 16205). EPA's proposed approval of this SIP submission addresses Delaware's compliance with the portion of CAA Section 110(a)(2)(C) & (J) relating to the CAA's part C permit program for the 1997 Ozone NAAQS, because this proposed approval would approve regulating NOX as a precursor to ozone in Delaware's SIP in accordance with the Federal Register action dated November 29, 2005 (70 FR 71612) that finalized NOX as a precursor for ozone regulations set forth at 40 CFR 51.166 and in 40 CFR 52.21.

We have determined that the current amendments to Delaware's PSD permit program at Regulation 1125, section 3.0, as submitted on April 1, 2010, meet the minimum requirements of 40 CFR 51.166 and the CAA. This SIP proposal is being proposed as a full approvable revision to the Delaware SIP. No other changes to the currently approved SIP are being proposed for approval at this time.

II. Summary of SIP Revision

This rule establishes a state construction permit program consistent with the federal CAA's Title I program and implementing regulations at 40 CFR 51.166, “Prevention of Significant Deterioration of Air Quality.” Regulation 1125, section 3.0 is part of the SIP and sets forth the criteria and procedures for major stationary sources to obtain a permit to construct, operate and/or modify a major stationary source.

As required by 40 CFR Part 51, Subpart I—“Review of New Sources and Modifications,” this rule adopts criteria and procedures for the prevention of significant deterioration of air quality that are consistent with the governing federal regulation at 40 CFR 51.166. Promulgation of this rule by the Legislature was necessary for Delaware to fulfill its responsibilities under 40 CFR Part 51 and the CAA, as amended. Revisions to the Delaware rule simply added new references to include NOX as a precursor to ozone to comport with federal counterpart language. The Delaware Department of Natural Resources and Environmental Control has now submitted a final rule Regulation 1125, section 3.0 as a proposed revision to the SIP. We are now proposing to approve NOX as a precursor to ozone in the Delaware SIP.

III. Proposed Action

Delaware's proposed SIP submission addresses changes needed to be equivalent to the CAA's part C PSD permit program. This SIP submission also corrects deficiencies identified by EPA in the March 27, 2008 Federal Register action entitled, “Completeness Findings for Section 110(a) State Implementation Plans for the 8-hour Ozone National Ambient Air Quality Standards (1997 Ozone NAAQS)” (73 FR 16205). EPA's proposed approval of this SIP submission addresses Delaware's compliance with the portion of CAA Section 110(a)(2)(C) & (J) relating to the CAA's part C permit program for the 1997 Ozone NAAQS, because this proposal would approve regulating NOX as a precursor to ozone in Delaware's SIP in accordance with the Federal Register action dated November 29, 2005 (70 FR 71612) that finalized NOX as a precursor for ozone regulations set forth at 40 CFR 51.166 and in 40 CFR 52.21.

EPA is proposing to approve this Delaware SIP revision for the changes made to Regulation 1125, section 3.0, as was submitted on April 1, 2010. EPA is soliciting public comments on the issues discussed in this document. These comments will be considered before taking final action.

IV. 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 proposes to approve state law as meeting Federal requirements and does not impose additional requirements beyond those imposed by state law. For that reason, this proposed 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 Start Printed Page 26681application 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).

This proposed rule, for the inclusion of NOX as a precursor to ozone in Delaware for the PSD program, 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 will not impose substantial direct costs on tribal governments or preempt tribal law.
