Dear Regional Administrator Steinberg: 

~~~~~~ 1c~°7 

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 of two 8-hour ozone nonattainment areas: the Northern New 

Jersey/NE;w York/Connecticut nonattainment area, which includes a portion 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 of June 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 of the 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 of June 15, 2010. This attainment demonstration is 

based primarily on photochemical air quality simulation modeling that includes the 

1 The USEPA finalized 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 :

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

plausible demonstration also incorporates the latest scientific information from the University of 

Maryland that considers some of the uncertainties and biases when using atmospheric models . 

The remainder of the SIP revision addresses the other mandatory SIP elements for 8-hour ozone 

and other related issues, with the exception of the Reasonably Available Control Technology 

analysis, which we transmitted to you as final on August 7, 2007 (under a cover letter dated 

August 1, 2007). Specifically, the primary additional SIP components include: 

" A demonstration that the State will 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; 

A Reasonably Available Control Measures (RACM) analysis which demonstrates that 

there are no other reasonable measures that would advance the nonattainment areas' 

attainment date by one year; 

" 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 conformance with the SIP; 

" General conformity emission budgets for use by McGuire Air Force Base and Lakehurst 

Naval Air Station to ensure that emissions from their operations also conform to the 

requirements of the SIP; 

" A request that the USEPA make a finding that three out of the four 1-hour ozone 

nonattainment areas to which New Jersey belongs are meeting the 1-hour standard ; and, 

" A request that the USEPA, in reviewing the attainment demonstrations and all other SIP 

revisions from other 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 of this 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 the proposal until the close of 

business on August 8, 2007. A summary of comments received on this SIP revision, as well as 

the State's responses to those comments, is included as part of the enclosed SIP submittal 

document in Appendix H. Appendix H also includes a summary of all substantive NJDEPinitiated changes to the SIP document since proposal. In our submittal of the proposal version of 

SIP revision, we requested that the USEPA parallel process this SIP revision . 

If you have any questions regarding this proposal, please contact William O'Sullivan, 

Director of the Division of Air Quality, at (609) 984-1484 . 
Sincerely yours, 

.,
