EGAS – means Economic Growth Analysis System. The USEPA’s
EGAS model is used to project emissions inventories for various
pollutants. These growth factors, represent the ratio of a
projection year's activity level from a base year activity
EGU – means electric generating unit. A combustion or
steam generating source used for generating electricity that
delivers all or part of its power to the electric power distribution
grid for commercial sale.
Eight-Hour Ozone Standards – Since 1971, the U.S. Environmental
Protection Agency (USEPA) has established national air quality
standards for ozone. Revised in 1997, the previous national
air quality standard for ozone was 0.08 parts per million (ppm),
or 80 parts per billion (ppb), averaged over 8 hours. Revised in 2008, the current NAAQS is 0.075 ppm, or 75 ppb, averaged over 8 hours. For a
given geographic area to be in compliance, its fourth highest
8-hour concentration in a year, averaged over three years,
must be equal to or less than that amount.
Electric generating unit (EGU) – means a combustion
or steam generating source used for generating electricity
that delivers all or part of its power to the electric power
distribution grid for commercial sale.
Emergency – means any situation that arose from sudden
and reasonably unforeseeable events beyond the control of an
owner or operator of a facility, such as an unforeseen system
capacity shortage caused by an act of God, that requires immediate
corrective action to prevent system collapse or to restore
normal operations at the facility.
Emission – release of pollutants into the air from a
source. We say sources emit pollutants. Continuous
emission monitoring systems (CEMS) are machines which some
large sources are required to install, to make continuous measurements
of pollutant release.
Emission Factor – The relationship between the amount of pollution
produced and the amount of raw material processed. For example,
an emission factor for a blast furnace making iron would be
the number of pounds of particulates per ton of raw materials.
Emission Statement – means a report of the actual annual
emissions of a facility submitted by the owner or operator
to the Department pursuant to the requirements of N.J.A.C.
Enforcement – The legal methods used to make polluters comply
with air quality regulations. Enforcement methods include citations
of polluters for violations of the law (citations are much
like traffic tickets), fines, and even jail terms. The USEPA and the
state and local governments are responsible for enforcement
of the Federal Clean Air Act, but if they don't enforce the law, members
of the public can sue the USEPA or the states to get action. Citizens
can also sue violating sources, apart from any action the USEPA or
state or local governments have taken. Before the 1990 Clean
Air Act, all enforcement actions had to be handled through
the courts. The 1990 Clean Air Act gave the USEPA authority so that,
in some cases, the USEPA can fine violators without going to court
first. The purpose of this new authority is to speed up violating
sources' compliance with the law and reduce court time and
Equipment – means any device capable of causing the
emission of an air contaminant either directly or indirectly
to the outdoor atmosphere, and any stack or chimney, conduit,
flue, duct, vent or similar device connected or attached to,
or serving the equipment. This term includes, but is
not limited to, a device in which the preponderance of the
air contaminants emitted is caused by a manufacturing process.
EPA (or USEPA) – means the United States Environmental
