## Abstract

The Environmental Protection Agency (EPA) is approving a request from New Jersey to revise its State Implementation Plan (SIP) to incorporate revisions to the motor vehicle enhanced inspection and maintenance (I/M) program. New Jersey has made several amendments to its I/M program and has requested that the SIP be revised to include these changes. EPA is approving New Jersey's amendments to its I/M program to discontinue idle tests on model years 1995 and older light duty gasoline vehicles, idle tests on heavy-duty gasoline vehicles and gas cap leak testing. In addition, heavy-duty gasoline vehicles equipped with on-board diagnostics (OBD) will be subject to OBD testing with this revision. The intended effect of this action is to maintain consistency between the State-adopted rules and the federally approved SIP.
