IV. History of New Jersey's Attainment Demonstration and Rate of Progress SIPs
On August 31, 1998, New Jersey submitted to the USEPA a SIP revision containing a demonstration of attainment of the one-hour ozone NAAQS for the Northern New Jersey/New York City/Long Island and Philadelphia/Wilmington/Trenton nonattainment areas.5 This original attainment demonstration submittal is hereafter referred to as the State’s Phase II Ozone SIP. The Phase II Ozone SIP submittal provided for an attainment demonstration as required by 42 U.S.C. §7511a(c)(2)(A), §182(c)(2)(A) of the Clean Air Act and addressed the USEPA’s subsequent requirements regarding attainment demonstration for the one-hour NAAQS for ozone.6,7
New Jersey used a "weight of evidence" to determine the emission reductions needed to attain the ozone standard. A weight of evidence analysis combines results from advanced photochemical grid models and the most recent air quality data to improve the estimate
