NAA – means Nonattainment Area. A geographic area in
which the level of criteria airs pollutant is higher than the
level allowed by the federal standards. A single geographic
area may have acceptable levels of one criteria air pollutant
but unacceptable levels on one or more other criteria air pollutants;
thus, an area can be both attainment and nonattainment at the
National Ambient Air Quality Standard
(NAAQS) – means
an ambient air quality standard promulgated at 40 CFR 50.
National Emissions Standards for Hazardous
Air Pollutants (NESHAPS) – Emissions standards set by the USEPA for an air pollutant
not covered by NAAQS that may cause an increase in fatalities
or in serious, irreversible, or incapacitating illness. Primary
standards are designed to protect human health, secondary standards
to protect public welfare (e.g. building facades, visibility,
crops, and domestic animals).
NESCAUM – means Northeast States for Coordinated Air
Use Management. NESCAUM is a nonprofit association of air quality
agencies in the Northeast. The Board of Directors consists
of the air directors of the six New England states (Connecticut,
Maine, Massachusetts, New Hampshire, Rhode Island, and Vermont),
New Jersey, and New York. The staff of thirty provide scientific,
technical, analytical, and policy support to the air quality
programs of the eight Northeast states. NESCAUM works to create
effective solutions to critical clean air issues that harmonize
environmental, public health, economic, and other societal
goals through cutting-edge scientific research, policy analysis,
outreach, and demonstration projects.
New Source Performance Standards (NSPS) – U.S. federal standards
promulgated for major and minor sources on a category-category
basis. NSPS are national emission standards that are progressively
tightened over time to achieve a steady rate of air quality
improvement without unreasonable economic disruption. The NSPS
imposes uniform requirements on new and modified sources through
the nation. These standards are based on the best demonstrated
New Source Review (NSR) – A program used in development of
permits for new or modified industrial facilities which are
in a nonattainment area, and which emit criteria air pollutants.
The two major requirements of NSR are Best Available Control
Technology (BACT) and emission offset.
N.J.A.C. – means New Jersey Administrative Code.
NJMVC – means New Jersey Motor Vehicles Commission within
the New Jersey Department of Transportation.
NJTPA – means New Jersey Transportation Planning Authority.
The federally authorized Metropolitan Planning Organization
(MPO) for the 6 million people in the 13-county northern New
NLEV – means National Low Emission Vehicle. A
program that creates voluntary requirements that U.S. automakers
can adopt in lieu of compliance with other vehicle emission
control measures. The program applies to the manufacture of
new light-duty vehicles and new light-duty trucks up to 6,000
lb gross vehicle weight rating (GVWR).
Nitric Oxide (NO) – A gas formed by combustion under high
temperature and high pressure in an internal combustion engine.
NO is converted by sunlight and photochemical processes in
ambient air to nitrogen oxide. NO is a precursor of ground-level
ozone pollution, or smog.
Nitrogen Dioxide (NO2) – The result of nitric oxide combining
with oxygen in the atmosphere; major component of photochemical
Nitrogen Oxides (NOx) – A criteria air pollutant. Nitrogen
oxides are produced from burning fuels, including gasoline
and coal. Nitrogen oxides are smog formers, which react with
volatile organic compounds to form smog. Nitrogen oxides are
also major components of acid rain.
Nonattainment Area – A geographic area in which the
level of criteria air pollutant is higher than the level allowed
by the federal standards. A single geographic area may
have acceptable levels of one criteria air pollutant but unacceptable
levels on one or more other criteria air pollutants; thus,
an area can be both attainment and nonattainment at the same
Non-Road Emissions – Pollutants emitted by combustion engines
on farm and construction equipment, gasoline-powered lawn and
garden equipment, powerboats, outboard motors, and some portable
