Enclosed for your review and approval are revisions to the New Jersey State Implementation Plan (SIP) for the Attainment and Maintenance of the 8-Hour Ozone National Ambient Air Quality Standard. New Jersey is part oftwo 8-hour ozone nonattainment areas: the Northern New Jersey/NE;wYork/Connecticut nonattainment area, which includes aportion of New York and Connecticut, and the Southern New Jersey/Philadelphia nonattainment area, which includes all of Delaware and portions of Pennsylvania and Maryland. The primary purpose for this SIP revision is for New

Jersey to demonstrate that these two multi-state 8-hour ozone nonattainment areas will attain the 8-hour ozone NAAQS by their mandatory attainment date ofJune 15, 2010 . According to the United States Environmental Protection Agency (USEPA) guidance,' areas that have an attainment date of no later than June 15, 2010, must implement the emission reductions needed for attainment no later than the beginning ofthe 2009 ozone season (June 2009) . Otherwise the emission reductions will not affect the monitored ozone in 2009, which is the last ozone season before the attainment date ofJune 15, 2010 . This attainment demonstration is based primarily on photochemical air quality simulation modeling that includes the 1 The USEPAfinalized modeling guidance for 8-hour ozone attainment demonstrations in October of 2005 but subsequently incorporated the ozone guidance in the final 2007 guidance for regional haze and PM2 .5: USEPA .

New Jersey Is An Equal Opportunity Employer 0 Printed on Recycled Paper and Recyclableimplementation of numerous additional control measures prior to the summer of 2009. This

plausible demonstration also incorporates the latest scientific informationfromthe University of Maryland that considers some ofthe uncertainties and biases when using atmospheric models. The remainder ofthe SIPrevision addresses the other mandatory SIP elements for 8-hour ozone and other related issues, with the exception ofthe Reasonably Available Control Technology analysis, whichwe transmitted to you as final on August 7, 2007 (under a cover letter dated August 1, 2007) . Specifically, the primary additional SIP components include: " Ademonstration that the Statewill more than meet its Reasonable Further Progress targets for both 2008 and 2009, using the same control measures applied in the State's 2009 attainment demonstration; AReasonably Available Control Measures (RACM) analysis whichdemonstrates that there are no other reasonable measures that would advance the nonattainment areas' attainment date by oneyear; " Contingency measures for the 2008 Reasonably Further Progress (RFP) milestone and the 2009 attainment milestone; Onroad vehicle emission budgets for use by the Metropolitan Planning Organizations to ensure their plans and programs are in conformancewith the SIP ; " General conformity emission budgets for use by McGuireAir Force Base and Lakehurst Naval Air Station to ensure that emissions fromtheir operations also conform to the requirements ofthe SIP ; " Arequest that the USEPAmake a finding that three out ofthe four 1-hour ozone nonattainment areas to which New Jersey belongs are meeting the 1-hour standard; and, " Arequest that the USEPA, in reviewing the attainment demonstrations and all other SIP revisions fromother states, take into consideration their impact on New Jersey's attainment obligations, and insure that other states are doing all they can to help the multi-state nonattainment areas attain as soon as practicable. On June 15, 2007, we forwarded a copy ofthis proposed SIP to you for review . The New

Jersey Department of Environment Protection (NJDEP) held a public hearing on New Jersey's proposal on August 1, 2007, and accepted written comments relevant to theproposal until the close of business on August 8, 2007. Asummary ofcomments received on this SIP revision, as well as the State's responses to those comments, is included as part ofthe enclosed SIP submittal document in Appendix H . Appendix Halso includes a summary ofall substantive NJDEPinitiated changes to the SIP document since proposal . In our submittal ofthe proposal version of SIPrevision, we requested that the USEPAparallel process this SIPrevision. If you have any questions regarding this proposal, please contact WilliamO'Sullivan, Director ofthe Division ofAir Quality, at (609) 984-1484.Sincerely yours,
