I. Background

On December 15, 2009, the Maryland Department of the Environment (MDE) submitted a revision to the Maryland Start Printed Page 34671SIP. The SIP revision (#09-04) pertains to changes in emission limitations for the R. Paul Smith Power Station in Washington County. This facility had annual nitrogen oxides (NOx), ozone season NOx, and sulfur oxides (SO2) emission limits that were established under EPA-approved Maryland regulation COMAR 26.11.27—Emission Limitations for Power Plants, which was adopted by the State to meet statutory requirements under the Maryland Healthy Air Act (HAA). The HAA allows R. Paul Smith to operate without complying with the emission limitations set forth in this statute if PJM Interconnection, Inc. (PJM) determines that termination of operation of the facility will adversely affect the reliability of electrical service in the PJM region. Subsequent to Maryland's adoption of COMAR 26.11.27 and EPA's approval of the rule into the Maryland SIP, PJM determined that the R. Paul Smith facility is needed to maintain electricity reliability in the State. The HAA requires that if R. Paul Smith units 3 and 4 are allowed to operate without complying with the emissions limitations established in the statute, certain conditions must be met. These conditions require that the facility operate at emissions levels that are lower than the highest level measured at the facility during the calendar years from 2000 through 2004, and that MDE review the operations of the facility, then adopt regulations to establish an alternative emissions requirement for the facility. In accordance with these statutory requirements, MDE revised COMAR 26.11.27 to establish alternative emission limits for these two Electric Generating Units at R. Paul Smith.

II. Summary of SIP Revision

COMAR 26.11.27 is revised to establish new emission limitations for R. Paul Smith Power Station. The NOx annual tonnage limits for R. Paul Smith is revised from 416 tons to 1390 tons starting with the 2009 control period, the NOx ozone season limit is revised from 140 tons to 545 tons starting with the 2009 ozone season, and the SO2 annual tonnage is revised from 1002 tons to 4590 tons starting with the 2009 control period.

Because the SIP revision increases emissions from this facility, MDE was required to meet section 110(l) of the CAA. Section 110(l) requires that the revision not interfere with any applicable requirement concerning attainment and reasonable further progress, or any other applicable requirement of section 110. EPA's analysis confirmed that the SIP revision does not interfere with any section 110(l) requirements. A more detailed discussion of EPA's rationale for approval of this Maryland SIP revision may be found in the technical support document (TSD) for this action.

III. Proposed Action

EPA is proposing to approve the SIP revision submitted by the State of Maryland on December 15, 2009. The SIP revision incorporates revisions to the emission limitations that apply to the R. Paul Smith Power Station in Washington County. 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 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, 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 approving revisions to the emission limitations for R. Paul Smith Power Station 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.
