Start Preamble

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

EPA is approving this SIP revision in accordance with the Clean Air Act (CAA).

DATES:

Effective Date: This final rule is effective on December 10, 2008.

SUPPLEMENTARY INFORMATION:

I. Background

On July 14, 2008 (73 FR 40228), EPA published a notice of proposed rulemaking (NPR) for the State of Delaware. The NPR proposed approval of the Regulation 1148—Control of Stationary Combustion Turbine Electric Generating Unit Emissions. The formal SIP revision was submitted by the State of Delaware on September 11, 2007.

II. Summary of SIP Revision

Regulation 1148 requires that an owner or operator of an existing stationary combustion turbine electric generating unit located in Delaware with a base-load nameplate capacity of 1 megawatt (MW) or greater must, by May 1, 2009, either demonstrate that the existing stationary combustion turbine generating unit meets the emission limits listed below or must install NOX emission controls designed to meet these limits:

  • For CTs that burn gaseous fuel—42 parts per million volume (ppmv) NOX.
  • For CTs that burn liquid fuel—88 ppmv NOX.

Design of these limits was based on anticipated NOX emissions if water injection pollution control equipment were installed. The six CTs affected by this regulation operate without any NOX pollution control equipment, although they are subject to regulations designed to control NOX emissions. Delaware determined that the six sources could achieve significant reductions in their NOX emissions through the use of water injection equipment. EPA has previously recognized this equipment and technology as reasonably available control technology (RACT). Water injection is a proven, feasible technology that has been used in other states to reduce NOX emissions.

This revision will reduce NOX emissions from CTs by 40 percent, or by 0.88 tons per day to approximately 1.33 tons per day. Such a reduction will significantly improve air quality, particularly on days when CTs normally operate, i.e., hot humid days and when weather conditions are conducive to forming ground-level ozone, and is one of the many regulatory steps taken to allow Delaware to attain the National Ambient Air Quality Standards (NAAQS) by 2010.

Other specific requirements of Regulation 1148 and the rationale for EPA's proposed action are explained in the NPR and will not be restated here. No public comments were received on the NPR.

III. Final Action

EPA is approving Regulation 1148—Control of NOX Emissions from Stationary Combustion Turbine Electric Generating Units as a revision to the Delaware SIP.

IV. Statutory and Executive Order Reviews

A. General Requirements

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, as Start Printed Page 66555appropriate, 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 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 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 January 9, 2009. 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 to control NOX emissions from stationary combustion turbine electric generating units in Delaware may not be challenged later in proceedings to enforce its requirements. (See section 307(b)(2).)
