State Implementation Plans (SIPS)

SIP Name Action Date Description
The update of the early transportation conformity budgets for Mercer County
January 2, 2008
"The New Jersey Department of Environmental Protection (Department) is proposing revisions to New Jersey’s State Implementation Plan (SIP) to update the initial early transportation conformity budgets for PM2.5 to incorporate the latest planning assumptions."
December 17, 2007
January 28, 2008
The Federal Clean Air Act Infrastructure Requirements
December 7, 2007

"The New Jersey Department of Environmental Protection (Department) is proposing revisions to New Jersey’s State Implementation Plan (SIP) to address the requirements under 42 U.S.C. § 7410, Section 110(a)(1) and (2) of the Clean Air Act, for the 1997 8-Hour Ozone and the 1997 Fine Particulate Matter (PM2.5) National Ambient Air Quality Standards (NAAQS)."

8 Hour Ozone
October 29, 2007
"The New Jersey Department of Environmental Protection is proposing a revision to its State Implementation Plan (SIP) to implement the 8-Hour Ozone National Ambient Air Quality Standard (NAAQS). The core of this proposed SIP revision is the State’s demonstration that its two multi-state 8-hour ozone nonattainment areas will attain the 8-hour ozone NAAQS by their mandatory attainment date of June 15, 2010. The remainder of the proposed SIP revision addresses the other mandatory SIP elements for 8-hour ozone (with the exception of a Reasonable Available Control Technology (RACT) analysis, which the Department of proposed on February 2, 2007 and will submit as final to the USEPA separately) and other related issues."
June 15, 2007
August 1, 2007
CAIR
June 19, 2007
The Federal Clean Air Interstate Rule (CAIR) program, as established in the Federal rules, starts in 2009 for the annual and ozone season NOx control periods, and 2010 for the annual SO2 control period, and prescribes the participation by New Jersey’s large stationary combustion units in the Federal CAIR cap and trade programs at 40 CFR Part 97, which are designed to reduce emissions of NOx and SO2 in the eastern half of the United States. The Department is proposing new rules to allocate the NOx allowances differently than the Federal rules to satisfy the Federal requirements for an abbreviated SIP for CAIR (40 CFR Part 97 Subpart EE and Subpart EEEE).
February 5, 2007
March 28, 2007
RACT
August 1, 2007
The focus of the proposed SIP revision is on Reasonable Available Control Technology (RACT) for ozone attainment. Provisions relevant to other aspects of the ozone, fine particulate matter and regional haze SIP are included where appropriate.

Transport SIP Letter
December 22, 2006
"This letter describes the State's plan for addressing the transported emission requirements prescribed in Section 110(a)(2)(D)(i) of the Clean Air Act. This letter was sent to the EPA Region 2 by Commissioner Jackson on December 22, 2006. The transported emissions related actions will be part of various SIP proposals, including but not limited to the RACT proposal (submitted to the EPA on February 7, 2007), the CAIR rule proposal (submitted to the EPA on February 7, 2007) and the Regional Haze proposal (due to the EPA by December 2007). All these SIP proposals have, or will, go through a public comment process prior to being finalized for submission to the EPA."
8 Hour Carbon Monoxide National Ambient Air Quality Standard , 1 Hour Ozone National Ambient Air Quality Standard, Fine Particulate Matter National Ambient Air Quality Standard and the 2002 Periodic Emission Inventory
May 2006
The proposed SIP revisions include updated carbon monoxide and ozone budgets for northern New Jersey for transportation conformity purposes that incorporate updated planning assumptions; a revised general conformity emission budget for McGuire Air Force Base to ensure that increases in activity at the McGuire Air Force Base conform with the ozone SIP; a fine particulate matter, PM2.5, transportation conformity budget for northern New Jersey for the interim period prior to the PM2.5 attainment demonstration SIP; a carbon monoxide limited maintenance plan for Camden County and the nine not-classified areas for the second ten-year compliance period; and the 2002 periodic emission inventory.
February 28, 2006
Carbon Monoxide and 1 Hour Ozone National Ambient Air Quality Standards
May 3, 2004
This document establishes updated transportation conformity budgets for New Jersey's Metropolitan Planning Organizations (MPOs) because of changes to emission prediction models.

Enhanced Inspection and Maintenance (I/M) Program for the State of New Jersey
November 27, 2002
Revision to the State of New Jersey's enhanced inspection and maintenance (I/M) program State Implementation Plan (SIP) for securing EPA approval for the State to extend the new vehicle emission inspection exemption from the current one inspection cycle (i.e., 2 years) to two inspection cycles (i.e., 4 years).

Proposed Revision to NJ's 15% Rate of Progress Plan
Low Emission Gasoline Program
November 16, 1998
Proposed SIP Revision requesting a waiver under section 211(c)(4)(C) of the Clean Air Act. This request is being made because the proposed new fuel requirements are different from, and more stringent than, the RFG requirements currently in effect in New Jersey. The State has determined that the additional emission reduction benefits that these new gasoline standards would generate will be necessary to (1) meet the new eight-hour NAAQS for ozone and (2) address in part the uncertainty in attaining the one-hour NAAQS.
Phase II Ozone SIP
June 30, 1998
Proposed revision for the Attainment and Maintenance of the Ozone National Ambient Air Quality Standards.
