## Abstract

EPA is approving a Clean Air Act State Implementation Plan (SIP) revision submitted by the State of Maine. On December 17, 1998 (63 FR 69594), EPA proposed to approve a revision to the Maine SIP. This SIP revision request was submitted to EPA for approval on November 19, 1998 by the Maine Department of Environmental Protection (DEP) for vehicle inspection and maintenance (I/M). That submittal requested further flexibility from I/M requirements applicable to the Ozone Transport Region (OTR) in light of the air quality status of the area. EPA proposed approval of the State's I/M program under the concept of OTR "restructuring." EPA received no comments on the December 17, 1998 proposal. This action is being taken under section 110 of the Clean Air Act.
