Environmental Protection Agency (EPA).


Partial withdrawal of proposed rule.


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).


The proposed rule for COMAR is withdrawn as of September 4, 2008.

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 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23, 2008 letter requested that EPA finalize its rulemaking with respect to the rest of the SIP Revision that is not withdrawn.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 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.
