Notice of SIP Revision-SO2 Redesignation Request

The New Jersey Department of Environmental Protection has revised its State Implementation Plan (SIP) to request that the United States Environmental Protection Agency (USEPA) redesignate to attainment the Warren County SO2 nonattainment area. In this SIP revision, New Jersey is demonstrating it has attained the 1971 primary and secondary SO2 National Ambient Air Quality Standards (NAAQS) to protect its citizens’ health through implementation of regulations to control SO2 emissions within its borders, as well as past actions to reduce SO2 emissions from large, upwind sources in Pennsylvania that were causing nonattainment in New Jersey. This SIP revision provides a limited maintenance plan for the Warren County nonattainment area to be redesignated to attainment. This redesignation plan request is being submitted as a limited maintenance plan because the SO2 air quality levels at ambient monitoring sites in Warren County are 85 percent or more below the NAAQS pursuant to Section 175A of the CAA.  This document acknowledges the improvement in outdoor sulfur dioxide air quality by requesting that the USEPA redesignate the New Jersey Warren County SO2 nonattainment area to attainment in accordance with the Clean Air Act as amended in 1990.
