#  Approval and Promulgation of Air Quality Implementation Plans; Maryland; Transportation Conformity Regulations; Withdrawal of Direct Final Rule

**AGENCY:**

Environmental Protection Agency (EPA).

**ACTION:**

Withdrawal of direct final rule.

**SUMMARY:**

On June 18, 2010 (75 FR 34644), EPA published a direct final 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 direct final rule approving Maryland's conformity regulations. This withdrawal action is being taken under section 110 of the Clean Air Act.

**DATES:**

The direct final rule published at 75 FR 34644 on June 18, 2010, is withdrawn as of August 12, 2010.

**ADDRESSES:**

EPA has established docket number EPA-R03-OAR-2008-0871 for this action.
