## Abstract

EPA is approving a request from New Jersey to revise its State Implementation Plan (SIP) to incorporate revisions to the enhanced inspection and maintenance (I/M) program. New Jersey has made several amendments to its I/M rules to comply with EPA regulations and to improve performance of the program and has requested that the SIP be revised to include these changes. Chief among the amendments EPA is approving is New Jersey's On-Board Diagnostic (OBD) program. EPA is approving New Jersey's latest I/M rule changes. The intended effect of this action is to maintain consistency between the State-adopted rules and the federally approved SIP.
