Revision to the State Implementation Plan (SIP) for the Attainment and Maintenance of the Ozone Nation Ambient Air Quality Standards

This document revises New Jersey’s State Implementation Plan (SIP) for the Attainment and Maintenance of the Ozone National Ambient Air Quality Standards (NAAQS). Specifically, the purpose of this SIP revision is to: 1) replace the State’s 15 percent Rate of Progress (ROP) plans that was disapproved by the United States Environmental Protection Agency (USEPA) on December 12, 1997; and 2) provide for a 1999 Transportation Conformity Budget. The State’s 15 percent ROP plans were disapproved by the USEPA based on the Federal Agency’s finding that, due to delays in starting the enhanced inspection and maintenance (I/M) program, New Jersey cannot timely achieve the required 15 percent emission reductions
