[EPA-R03-OAR-2007-1001; FRL-8709-6]

 
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DATES: The proposed rule for COMAR 26.11.27.03B(7)(a)(iii) is withdrawn 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; NOX and 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 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rest of the SIP Revision that is not withdrawn.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.
