Summary

The Environmental Protection Agency (EPA) is proposing to approve a State Implementation Plan (SIP) revision submitted by the New Jersey Department of Environmental Protection. The SIP revision consists of the following: 2011 calendar year ozone precursor emission inventories for volatile organic compounds, oxides of nitrogen and carbon monoxide for the Northern New Jersey-New York-Connecticut area classified as Moderate ozone nonattainment for the 2008 8-hour ozone standard, and Southern New Jersey-Philadelphia ozone nonattainment area classified as Marginal ozone nonattainment for the 2008 8-hour ozone standard. In addition, the SIP revision also consists of the 2011 calendar year statewide periodic emissions inventory for particulate matter with an aerodynamic diameter less than or equal to 2.5 microns (PM<INF>2.5</INF>) and the associated PM<INF>2.5</INF> and/or Regional Haze precursors. The pollutants included in this inventory include volatile organic compounds, oxides of nitrogen, PM<INF>2.5</INF>, particulate matter with an aerodynamic diameter less than or equal to 10 microns, ammonia and sulfur dioxide. Emission inventories are needed to develop and assess new control strategies that the states may use in attainment demonstration SIPs for the new National Ambient Air Quality Standards for ozone and PM<INF>2.5</INF>. The inventory may also serve as part of statewide inventories for purposes of regional modeling in ozone and Regional Haze transport areas. The inventory plays an important role in modeling demonstrations for areas classified as nonattainment for ozone, carbon monoxide and PM<INF>2.5</INF>.
