Environmental Protection Agency (EPA).


Final rule.


EPA is approving a State Implementation Plan (SIP) revision submitted by the State of Maryland. This revision pertains to regulations for emission limitations at 15 Maryland power plants. The intended effect of this action is to approve, with one exception, Maryland's regulation which establishes statewide tonnage caps for emissions of nitrogen oxides (NOX) and sulfur dioxide (SO2) from 15 coal-fired electric generating units (EGUs). The exception pertains to a portion of the rule that Maryland requested EPA take no further action on. The provision, which EPA has determined has no impact on the rule that is being finalized today, will be withdrawn in a separate notice. This SIP action is being taken under the Clean Air Act (CAA).


Effective Date: This final rule is effective on October 6, 2008.

I. Background

On April 6, 2006, Maryland signed into law the Healthy Air Act (Ch. 23, Acts of 2006). The Healthy Air Act establishes limits on the amount of NOX and SO2 emissions that affected facilities can emit, and does not permit the use of allowances to achieve compliance. To implement the Healthy Air Act, the Maryland Department of the Environment (MDE) adopted COMAR 26.11.27, Emission Limitations for Power Plants. These regulations require the installation of on-site pollution controls at 15 Maryland power plants and will ensure that appropriate local emission reductions will occur where they are needed in order to attain the 8-hour ozone and fine particulate matter National Ambient Air Quality Standards (NAAQS) by 2010.

A formal SIP revision (#07-10) was submitted by MDE on July 12, 2007. On January 10, 2008 (73 FR 1851), EPA published a notice of proposed rulemaking (NPR) for the State of Maryland. The NPR proposed approval of emission limitations and related requirements for NOX and SO2 at 15 coal-fired electric generating units in Maryland. No public comments were received on the NPR.

On June 23, 2008, MDE submitted a letter withdrawing a portion of the July 12, 2007 submittal. The withdrawal is only for COMAR This provision requires a unit that exceeds its ozone season NOX emissions Start Printed Page 51600limit to surrender ozone season NOX allowances equivalent to the number of tons of NOX emitted in excess of the limit. The June 23, 2008 letter requested that EPA finalize its rulemaking with respect to the rest of the SIP Revision that is not withdrawn. EPA determined that removal of regulation COMAR does not impact the rest of the requirements in COMAR 26.11.27, and is severable. By separate action, EPA will withdraw this provision as requested by MDE.

II. Summary of SIP Revision

The MDE is requesting that regulation COMAR 26.11.27, establishing tonnage caps for emissions of NOX and SO2 from 15 coal-fired EGUs in Maryland, be approved. The purpose of these regulations is to help bring Maryland into attainment with the NAAQS for 8 hour ozone and fine particulate matter by the 2010 attainment deadline. The 15 affected units are as follows:

Electric generating unitJurisdiction
Constellation Energy Group System
Brandon Shores 1 & 2Anne Arundel County.
H. A. Wagner 2 & 3Anne Arundel County.
C. P. Crane 1 & 2Baltimore County.
Mirant System
Chalk Point 1 & 2Prince George's County.
Dickerson 1, 2, & 3Montgomery County.
Morgantown 1 & 2Charles County.
Allegheny Energy
R. Paul Smith 3 & 4Washington County.

These regulations also establish monitoring and reporting requirements, and authorize the MDE to reduce or waive penalties for non-compliance under certain conditions and provide for judicial review of decisions by the MDE to grant a reduction or waiver of penalties.

III. Final Action

Maryland has met the requirements for submitting a SIP revision to limit NOX and SO2 emissions from 15 coal-fired EGUs. With the exception of COMAR, which will be withdrawn by separate action, EPA is approving the SIP revision.

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 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 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 November 3, 2008. Filing a petition for reconsideration by the Administrator of this final rule does not affect the finality of this rule for the purposes of judicial review nor does it extend the time within which a petition Start Printed Page 51601for judicial review may be filed, and shall not postpone the effectiveness of such rule or action.

This action approving Maryland's SIP revision concerning emission limitations for NOX and SO2 at 15 coal-fired EGUs may not be challenged later in proceedings to enforce its requirements. (See section 307(b)(2).)
