The New Jersey Department of Environmental Protection (DEP) is proposing revisions to
the New Jersey State Implementation Plan (SIP) for the Attainment and Maintenance of the
One-Hour Ozone National Ambient Air Quality Standard - New Jersey 1996 Actual Emission
Inventory and Rate of Progress (ROP) Plans for 2002, 2005, and 2007.
revisions are now available for download at the bottom of this page.
A public hearing is scheduled on the proposal on February 16, 2001 at 10:00 a.m. at:
The New Jersey Department of Environmental Protection
Public Hearing Room
401 East State Street
Trenton, New Jersey.
This hearing is being held in accordance with the provisions of Section 110(a)(2) of
the Clean Air Act, 42U.S.C. §7410: the Air Pollution Control Act (1954), N.J.S.A. 26:2C-1
et seq. And the Administrative Procedures Act, N.J.S.A. 52:14 B-1 et seq.
Written comments relevant to the proposal may be submitted until the close of business

To facilitate review and comment on the document ROP SIP and the new control measures
under consideration, the NJDEP's Bureau of Air Quality Planning will conduct a workshop,
on February 14, 2001, beginning at 1:00 p.m. at:
The New Jersey Department of Environmental Protection
401 East State Street, 7th floor large conference room
Trenton, New Jersey.
Ozone, a major constituent in smog, is produced by complex chemical reactions when its
precursors, volatile organic compounds and (VOCs) and oxides of nitrogen (NOx) react in
the presence of sunlight in the lower atmosphere (troposphere). The chemical reactions
that create ozone take place while the pollutants are being blown through the air by wind,
or otherwise transported. Therefore ozone is a regional as well as a local problem.
Despite substantial effort by federal and state government, elevated levels of ozone are
and remain a threat to public health.
Rate of Progress (ROP) Plan:
The Federal Clean Air Act Amendments of 1990 established a comprehensive program for
addressing the ozone problem. Specifically, 42 U.S.C. §7511a(c)(2)(B) calls for states
with one-hour ozone non-attainment areas with air quality classified as serious, severe or
extreme to reduce their VOC emissions by 3 percent of the 1990 baseline VOC emission level
averaged over each consecutive three (3) year period beginning in 1990 until the
attainment date. The attainment date is 2005 for the Philadelphia/Wilmington/ Trenton area
and 2007 for the Northern New Jersey/New York City/Long Island area. The State has already
successfully met the 1996 15 percent and 1999 24 percent ROP goals. The SIP submittal
containing the State's 15 percent and 24 percent plans was referred to as the State's
Phase I Ozone SIP.
This SIP revision contains the remaining ROP plans for each milestone year up to and
including the attainment years for each applicable non-attainment area, i.e., 2002 and
2005 for the Philadelphia/Wilmington/Trenton area and 2002, 2005, and 2007 for the
Northern New Jersey/New York City/Long Island area. The emissions projections in the
document demonstrate that, with already adopted control measures, the State has more than
enough VOC emission reductions and allowable NOx substitution emission reductions benefits
to meet the ROP target reductions. Detailed information on inventory projections by
emission source categories is found in Appendix II.
Relationships Between this ROP SIP and the State's Previous Attainment
On August 31, 1998, New Jersey submitted to the United States Environmental Protection
Agency (USEPA) a SIP revision containing a demonstration of attainment of the one-hour
ozone NAAQS for the Northern New Jersey/New York City/Long Island and
Philadelphia/Wilmington/Trenton non-attainment areas. This attainment demonstration
submittal was referred to as the State's Phase II Ozone SIP. The Phase II Ozone SIP
submittal provided for an attainment demonstration as required by 42 U.S.C.
§7511a(c)(2)(A) of the Clean Air Act. That SIP revision utilized emission projections to
predict future ozone concentrations, and demonstrate attainment with the ozone standard by
the attainment dates. Subsequently, the State addressed additional USEPA requirements
regarding the attainment demonstration for the one-hour NAAQS for ozone.
The purpose of the ROP submittal is to demonstrate steady, incremental progress (3
percent of the 1990 VOC baseline emission level averaged over each consecutive 3 year
period) leading towards the ultimate goal of attainment. The purpose of the attainment
demonstration, however, was to assess the overall emission reductions necessary to
actually achieve attainment, which could be greater than or less than the required ROP
reductions. The control measures included in this ROP SIP are consistent with the control
measures in the attainment demonstration, and the emission projections herein show greater
reductions than those needed to meet ROP requirements. Therefore, attaining the one-hour
ozone standard in New Jersey is predicted to require emission reductions that exceed ROP
The 1996 Inventory:
The Clean Air Act also requires at 42 U.S.C. 2182(a) that States with non-attainment
areas prepare current and accurate periodic emission inventories every three years, using
actual reported economic, fuel use and other relevant data for that year. These
inventories are expected to improve upon inventory estimates where predicted, as opposed
to available actual data, was used. This SIP revision also contains estimates of actual
emissions for the year 1996. Since this inventory is considered to be a better estimate of
emissions than that predicted in the State's Phase I Ozone SIP, it was used herein as the
starting point for the 2002, 2005, and 2007 inventory projections for certain emission
source categories. Detailed information on the 1996 inventory is contained in Appendix I.
In addition to demonstrating compliance with ROP requirements, this SIP revision
proposes new transportation conformity budgets. To develop these new budgets, revised
estimates of on-road emissions have been made incorporating newer 1999 vehicle
registration data that was used for allocating vehicle miles traveled by vehicle class,
and within each class, by vehicle age. In addition, the NOx benefits from Phase II of the
Reformulated Gasoline Program, the VOC and NOx benefits from the Tier II Motor Vehicle
Standard/Low Sulfur Gasoline Program, and the effects of heavy duty diesel (HDD) defeat
devices that disengage the engine's emission control system during highway driving - and
new HDD engine standards have been incorporated into the on-road emission estimates.
The SIP revision also contains a revised general conformity budget for McGuire Air
