NOTICE: PROPOSED RULES

ACTION: Approval and Promulgation of Air Quality Implementation Plans:

DOCUMENT ACTION: Partial withdrawal of proposed rule.

SUBJECT CATEGORY: Approval and Promulgation of Air Quality Implementation Plans; Maryland; NOX and SO2 Emissions Limitations for Fifteen Coal-Fired Electric Generating Units

DATES: The proposed rule for COMAR 26.11.27.03B(7)(a)(iii) is withdrawn as of September 4, 2008.

DOCUMENT 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 coalfired 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).

SUMMARY: Maryland; NOx and SO2 Emissions Limitations for Fifteen Coal-Fired Electric Generating Units,

SUPPLEMENTAL INFORMATION

See the information provided in the proposed rule entitled, ``Approval and Promulgation of Air Quality
Implementation Plans; Maryland; NOX and SO2 Emissions Limitations for Fifteen CoalFired 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 NOX emissions limit 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23, 2008 letter requested that EPA finalize its rulemaking with respect to the rest of the SIP Revision that is not withdrawn.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 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.
