## Abstract

This action serves to remove several conditions of EPA's January 28, 1997 interim final approval of the Commonwealth of Pennsylvania's State Implementation Plan (SIP) revision for its enhanced motor vehicle emissions inspection and maintenance (I/M) program. The Commonwealth has amended its SIP (since EPA granted conditional interim approval of that plan) to address these deficiencies. EPA is removing these conditions by approving two related SIP revisions submitted by Pennsylvania. These revisions serve to bolster the Commonwealth's I/M SIP, and to strengthen its I/M program. The intended effect of this action is to remove several conditions placed by EPA upon the approval of the Commonwealth's SIP. However, as Pennsylvania has yet to address several other outstanding rulemaking conditions on this same SIP, the Commonwealth's I/M SIP will continue to be conditionally approved, in accordance with the Clean Air Act, until the Commonwealth satisfies the remaining conditions.
