Approval and Promulgation of Air Quality Implementation Plans;

Maryland; NOX and SO2 Emissions Limitations for Fifteen Coal-Fired

Electric Generating Units

AGENCY: Environmental Protection Agency (EPA).

ACTION: Partial withdrawal of proposed rule.

SUMMARY: EPA is withdrawing a portion of a proposed rule pertaining to a State of Maryland State Implementation Plan (SIP) revision that establishes tonnage caps for emissions of nitrogen oxides

(NOX) and sulfur dioxide (SO2) from 15 coal-fired electric generating units. The proposed rule was published on January 10, 2008 (73 FR 1851). EPA is withdrawing a provision of the rule that

Maryland requested we take no further action on. EPA has determined that the provision has no impact on the remainder of the rule, which is being finalized by separate document. This SIP action is being taken under the Clean Air Act (CAA).

DATES: The proposed rule for COMAR 26.11.27.03B(7)(a)(iii) is withdrawn as of September 4, 2008.

SUPPLEMENTARY INFORMATION: See the information provided in the proposed rule entitled, ``Approval and Promulgation of Air Quality

Implementation Plans; Maryland; NOXand SO2

Emissions Limitations for Fifteen Coal-Fired Electric Generating

Units,'' located in the Proposed Rules section of the January 10, 2008

Federal Register (73 FR 1851). On June 23, 2008, the Maryland

Department of the Environment (MDE) submitted a letter withdrawing a portion of their July 12, 2007 submittal. The withdrawal only affects

COMAR 26.11.27.03B(7)(a)(iii). This provision requires a unit that exceeds its ozone season NOXemissions limit to surrender ozone season NOXallowances equivalent to the number of tons of NOXemitted 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23, 2008 letter requested that EPA finalize its rulemaking with respect to the rest of the SIP Revision that is not withdrawn.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 withdrawal of COMAR 26.11.27.03B(7)(a)(iii) does not impact the other requirements in COMAR 26.11.27 and is severable. The other portions of the January 10, 2008 proposed rule are not affected, and are being finalized in a separate notice.
