Approval and Promulgation of Air Quality Implementation Plans; New Hampshire; Vehicle Inspection and Maintenance Program; Restructuring OTR Requirements

EPA is approving a Clean Air Act State Implementation Plan (SIP) revision submitted by the State of New Hampshire. On December 17, 1998 (63 FR 69589), EPA proposed to approve a revision to the New Hampshire SIP for vehicle inspection and maintenance (I/M). This SIP revision request was submitted on September 4, 1998. The State supplemented it by a letter dated November 20, 1998 which provided additional information about the New Hampshire I/M program, and requested further flexibility from requirements applicable to areas in the Ozone Transport Region (OTR) in light of the air quality status of New Hampshire's ozone nonattainment areas. EPA proposed approval of New Hampshire's I/M program under the concept of OTR "restructuring" on December 17, 1998 and received no comments. This action is being taken under section 110 of the Clean Air Act.
