[EPA-R03-OAR-2008-0871; FRL-9188-4]


Approval and Promulgation of Air Quality Implementation Plans; 
Maryland; Transportation Conformity Regulations; Withdrawal of Proposed 
Rule

AGENCY: Environmental Protection Agency (EPA).

ACTION: Withdrawal of proposed rule.

-----------------------------------------------------------------------

SUMMARY: On June 18, 2010 (75 FR 34669), EPA published a proposed rule 
to approve revisions to the Maryland State Implementation Plan (SIP). 
The revisions amended Maryland's transportation conformity regulations 
and general conformity regulations. EPA's approval did not include 
Maryland's regulation regarding conflict resolution associated with 
conformity determinations (COMAR 26.11.26.06). EPA has determined that 
it cannot proceed with approval of these SIP revisions until and unless 
it also approves Maryland's regulation regarding conflict resolution 
associated with conformity determinations. Therefore, EPA is 
withdrawing its proposed rule to approve Maryland's conformity 
regulations. This withdrawal action is being taken under section 110 of 
the Clean Air Act.

DATES: The proposed rule published June 18, 2010 (75 FR 34669) is 
withdrawn as of August 11, 2010.

ADDRESSES: EPA has established docket number EPA-R03-OAR-2008-0871 for 
this action. The index to the docket is available electronically at 
http://www.regulations.gov and in hard copy at Air Protection Division, 
U.S. Environmental Protection Agency, Region III, 1650 Arch Street, 
Philadelphia, Pennsylvania 19103.
