Revisions to the New Jersey State Implementation Plan for the Attainment
and Maintenance of the One-Hour Ozone National Ambient Air Quality
The documents listed below, revisions to the New Jersey State Implementation
Plan (SIP) for the Attainment and Maintenance of the One-Hour Ozone National
Ambient Air Quality Standard - Update to Meeting the Requirements of the
Alternative Ozone Attainment Demonstration Policy - Additional Emission
Reductions, Reasonably Available Control Measure Analysis, and Mid-Course
Review, were submitted to the USEPA on Ocotber 8, 2001 by The
New Jersey Department of Environmental Protection (NJDEP).
Ozone is a highly reactive gas formed in the lower atmosphere or troposphere
from the chemical reaction involving oxides of nitrogen (NOx)
and volatile organic compounds (VOC) in the presence of sunlight. At elevated
levels, it causes a variety of human health effects as well as damage to
crops and materials. The United States Environmental Protection Agency (USEPA)
is required by the Clean Air Act to set health and welfare standards for
air pollutants, such as ozone. Among the provisions of the Clean Air
Act is the requirement that areas with ozone concentrations above certain
levels demonstrate that their plans will meet the health standard within
the time frame required by the Clean Air Act. New Jersey is required to make
such a demonstration for the eighteen of its twenty-one counties that have
not been designated as in attainment with the NAAQS for ozone. These counties
are associated with two multi-state nonattainment areas which are designated
the Philadelphia-Wilmington-Trenton Nonattainment Area and the New York-Northern
New Jersey-Long Island Nonattainment Area. Henceforth, these areas will be
called the Philadelphia Nonattainment Area and the New York Nonattainment
In New Jersey's Phase II Ozone SIP submittal of August 31, 1998, the State
provided air quality projections demonstrating that, under certain conditions
conducive to the formation of high ozone concentrations, attainment was plausible
without the need for further emission reductions beyond the measures already
implemented in New Jersey including those mandated in the Clean Air Act and
the regional reductions of NOx as embodied in the USEPA
NOx SIP call. The demonstration also identified and quantified
uncertainties in the projections. In reviewing New Jersey's, and other states'
demonstrations, the USEPA performed its own analyses and determined that
additional emission reductions were necessary for attainment.
Specifically, the USEPA determined that additional emission reductions in
the multi-state Philadelphia Nonattainment Area of 61.8 tons of VOC and 3.4
tons of NOx per summer day were needed. The additional emission
reductions needed in the multi-state New York Nonattainment Area were determined
to be 85 tons of VOC and 7 tons of NOx per summer day.
The USEPA required each state determined to have emission short falls, including
New Jersey, to submit a commitment to adopt additional control measures to
meet the level of reductions that the USEPA identified as necessary for
attainment. New Jersey chose to work through the Ozone Transport Region (OTR)
to develop a regional strategy regarding the measures necessary to meet the
additional reductions identified. OTR states are required to submit the
additional control measures developed through the regional process to the
USEPA by October 31, 2001.
New Jersey worked with other states in the Ozone Transport Commission (OTC)
to identify potential control measures to fill the additional emission reduction
requirements. The list of control measures which the OTC decided to pursue
for the additional emission reduction requirements include:
Reduction of VOCs from:
- commercial and consumer products
- architectural and industrial maintenance coatings
- solvent cleaning operations
- mobile equipment repair and refinishing operations
- portable fuel containers
Reduction of NOx from:
- selected stationary sources which include: industrial boilers, stationary
combustion turbines, stationary internal combustion engines and cement kilns.
This SIP revision outlines the process by which control measures were selected
which will address the additional emission reductions identified by the USEPA,
and discusses the content and emission benefits of each of the measures.
Implementation of the control measures outlined in this document by the involved
states and jurisdictions in the Philadelphia and New York Nonattainment Areas
will result in sufficient emission reductions to meet the USEPA identified
emission shortfalls in these areas. Additional benefits accrue if the control
measures are implemented in counties in the 100 kilometer area around the
As required by the USEPA, the State conducted a Reasonably Available Control
Measure (RACM) analysis for this SIP revision. Briefly, RACMs are any feasible
control measures that would advance the attainment date for a particular
nonattainment area. Although this analysis identified a number of Transportation
Control Measures (TCM) and other control measures that were feasible, none
would advance the attainment date for either nonattainment area in the State.
Therefore, given the control measures already contained in New Jersey's SIP
and the additional control measures in this SIP revision, New Jersey is moving
to attain the one-hour standard as expeditiously as practicable.
This SIP revision also contains New Jersey's Mid-Course Review which the
State committed to prepare in its August 31, 1998, Phase II Ozone SIP. New
Jersey has concluded from this analysis that it is currently on track to
attain the 1-hour ozone standard in both nonattainment areas in the State.
