SUPPLEMENTARY INFORMATION:

On October 7, 2009, the Delaware Department of Natural Resources and Environmental Control (DNREC) submitted a revision to its SIP for an amendment to Regulation No. 1146—Electric Generating Unit Multi-Pollutant Regulation.

I. Background

On November 16, 2006, DNREC submitted a revision to the Delaware SIP. This SIP revision pertained to a new regulation, Regulation No. 1146—Electric Generating Unit (EGU) Multi-Pollutant Regulation. The regulation was adopted in order to impose lower emissions limits of nitrogen oxides (NOx), SO2 and mercury in order to help Delaware attain and maintain the national ambient air quality standards (NAAQS) for ozone and fine particulate matter (PM2.5), as well as to assist Delaware in achieving the emissions reductions needed to support the State's 8-hour ozone reasonable further progress plan (RFP). EPA approved the SIP revision on August 28, 2008 (73 FR 50723).

II. Summary of SIP Revision

On October 7, 2009, EPA received a SIP revision to amend to Regulation No. 1146. This SIP revision was the result of a settlement agreement between Conectiv Delmarva Generating, Inc. and DNREC in December 2008. Conectiv had filed an appeal challenging the regulation for their Edge Moor 5 facility. The emissions limit of 2,427 tons per year limited the facility from operating in extreme circumstances in the event that failure at other production units would require them to exceed that limit in order to supply the needed electricity. The limit of 4,600 tons per year was determined to be an adequate limit after an analysis of the facility's history of operation and the estimate of future operations using the low sulfur (0.5%) residual fuel to generate electricity at the 446 megawatt oil-fired steam generating unit. Currently, the facility operates at a 10% capacity factor. If so required, the new emissions limit would allow the facility to operate at a 45% capacity factor.

This amendment to Regulation No. 1146 is a reasonable compromise between Conectiv and DNREC, which prevented a potential overturning of the regulation. Analysis supports that the increase in the SO2 emissions limit for the Edge Moor 5 facility will not lead to increased SO2 emissions on an annual basis, but will enable the facility to operate at a higher capacity if in the unusual circumstance it should be needed. Given that an increase in SO2 emissions is not expected from what they currently are at the facility, this revision will continue to help Delaware attain and maintain NAAQS for PM2.5.

III. Proposed Action

EPA is proposing to approve the Delaware SIP revision for the amendment to Regulation No. 1146—Electric Generating Unit Multi-Pollutant Regulation submitted on October 7, 2009. This revision pertains to a modification of the SO2 emissions limit for the Conectiv Edge Moor Unit 5 from 2,427 tons per year to 4,600 tons per year. 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 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 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 Start Printed Page 285Order 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, 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 proposed rule, pertaining to Delaware's amendment to Regulation 1146, the Electric Generating Unit Multi-Pollutant Regulation, 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.
