Glossary and Acronyms
ACO – means Administrative Consent Order. A legal agreement signed by the USEPA and an individual, business, or other entity through which the violator agrees to pay for correction of violations, take the required corrective or cleanup actions, or refrain from an activity. It describes the actions to be taken, may be subject to a comment period, applies to civil actions, and can be enforced in court.
ACT – means Alternative Control Technique.
Actual Emissions – means the rate at which an air contaminant is actually emitted, either directly or indirectly, to the outdoor atmosphere, in units of mass per calendar year, seasonal period, or other time period as specified.
Air Contaminant – means any substance, other than water or distillates of air, present in the atmosphere as solid particles, liquid particles, vapors or gases.
Air Pollutant – Any substance in air that could, in high enough concentration, harm man, other animals, vegetation, or material. Pollutants may include almost any natural or artificial composition of airborne matter capable of being airborne. They may be in the form of solid particles, liquid droplets, gases, or in combination thereof. Generally, they fall into two main groups: (1) those emitted directly from identifiable sources and (2) those produced in the air by interaction between two or more primary pollutants, or by reaction with normal atmospheric constituents, with or without photoactivation. Exclusive of pollen, fog, and dust, which are of natural origin, about 100 contaminants have been identified. Air pollutants are often grouped in categories for ease in classification; some of the categories are: solids, sulfur compounds, volatile organic chemicals, particulate matter, nitrogen compounds, oxygen compounds, halogen compounds, radioactive compound, and odors.
Air Pollution – The presence of contaminants or pollutant substances in the air that interfere with human health or welfare, or produce other harmful environmental effects.

Area Source or Nonpoint Source Air Emissions – These air pollution emission sources collectively represent individual sources of emissions that have not been inventoried as specific point or mobile sources. These individual sources treated collectively as nonpoint sources are typically too small, numerous, or difficult to inventory using the methods for the other classes of sources. Examples of key nonpoint sources include residential combustion, institutional and commercial boilers, agricultural burning, industrial and non-industrial solvents and graphic arts, degreasing, most agricultural sources, consumer products, architectural coatings, and sources of dust including roads and construction.
Attainment Area – A geographic area in which levels of a criteria air pollutant meet the health-based primary standard (national ambient air quality standard, or NAAQS) for the pollutant. An area may have an acceptable level for one criteria air pollutant, but may have unacceptable levels for others. Thus, an area could be both attainment and nonattainment at the same time. Attainment areas are defined using federal pollutant limits set by the USEPA.
BACT – means Best Available Control Technology. An emission limitation based on the maximum degree of emission reduction (considering energy, environmental, and economic impacts) achievable through application of production processes and available methods, systems, and techniques.

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. 7:27-21.
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 cost.
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.

These periodic inspection checks whether a car is being maintained to keep pollution down and whether emission control systems are working properly. Vehicles which do not pass inspection must be repaired. Under the 1990 Clean Air Act, some areas have enhanced inspection and maintenance programs, using special machines that can check for such things as how much pollution a car produces during actual driving conditions.
International Air Pollution – Pollution that moves across national borders. The 1990 Clean Air Act includes provisions for cooperative efforts to reduce pollution that originates in one North American country and affects another.
Interstate Air Pollution – In many areas, two or more states share the same air. We say these states are in the same air basin defined by geography and wind patterns. Often, air pollution moves out of the state in which it is produced into another state. Some pollutants, such as the power plant combustion products that cause acid rain, may travel over several states before affecting health, the environment, and property. The 1990 Clean Air Act includes many provisions, such as interstate compacts, to help states work together to protect the air they share. Reducing interstate air pollution is very important since many Americans live and work in areas where more than one state is part of a single metropolitan area.

Nitrogen Dioxide (NO2) – The result of nitric oxide combining with oxygen in the atmosphere; major component of photochemical smog.
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 time.
Nonroad Mobile Source Air Emissions –Nonroad mobile air pollution emissions sources are also called “off-highway” mobile sources. These are defined as a nonroad engine or nonroad vehicle. As per 40 CFR 51.50, a nonroad engine is an internal combustion engine (including the fuel system) that is not used in a [on-road] motor vehicle or a vehicle used solely for competition, or that is not affected by sections 111 or 202 of the CAA.

Examples of nonroad mobile sources include aircraft, airport ground support equipment, locomotives, CMVs, construction equipment powered by an internal combustion engine, agricultural equipment powered by an internal combustion engine, lawn and garden engines and equipment and recreational watercraft.
Offset – A method used in the 1990 Clean Air Act to give companies which own or operate large (major) source in a nonattainment area flexibility in meeting overall pollution reduction requirements when changing production processes. If the owner or operator of the source wishes to increase release of a criteria air pollutant, an offset (reduction of a somewhat greater amount of the same pollutant) must be obtained either at the same plant or by purchasing offsets from another company.
Onroad Mobile Source Air Emissions – Onroad mobile sources are also called “highway mobile sources.” These sources are the motor vehicles (e.g., automobiles, buses, trucks) traveling on local and highway roads. A motor vehicle is any self-propelled vehicle used to carry people or property on a street or highway (40 CFR 51.50).

Oxidant – A collective term for some of the primary constituents of photochemical smog.
Oxygenated Fuel (oxyfuel) – A special type of gasoline, which burns more completely than regular gasoline in cold start conditions; more complete burning results in reduced production of carbon monoxide, a criteria air pollutant. In some parts of the country, where carbon monoxide release from cars starting up in cold weather makes a major contribution to pollution, gasoline refiners must market oxygenated fuels, which contain higher oxygen content than regular gasoline.
Ozone – a gas which is a variety of oxygen. The oxygen gas found in the air consists of two oxygen atoms stuck together; this is molecular oxygen. Ozone consists of three oxygen atoms stuck together into an ozone molecule. Ozone occurs in nature; it produces the sharp smell you notice near a lightening strike. High concentrations of ozone gas are found in a layer of the atmosphere – the stratosphere – high above the Earth. Stratospheric ozone shields the Earth against harmful rays from the sun, particularly ultraviolet B. Smog’s main component is ozone; this ground-level ozone is a product of reactions among chemicals produced by burning coal, gasoline and other fuels, and chemicals found in products including solvents, paints, hairsprays, etc.

Point Source Air Emissions – As defined in 40 CFR 51.50, point sources are large, stationary (non-mobile), identifiable sources of emissions that release pollutants into the atmosphere. A point source in New Jersey includes, but is not limited to, a facility that is a major source under 40 CFR part 70 for one or more of the pollutants for which reporting is required by 40 CFR 51.15 (a)(1). This does not include the emissions of hazardous air pollutants, which are not considered in determining whether a source is a point source for ozone, PM2.5, and regional haze emissions inventory development and reporting. These point sources can be associated with a single point or group of points in space. Examples of important point source emissions categories include power plants, industrial boilers, petroleum refineries, cement plants, and other industrial plants.
In New Jersey, a point source is defined as a stationary facility that emits or has the potential to emit at or above any of the following thresholds:
• 10 tons per year of VOC
• 25 tons per year of NOx
• 100 tons per year of carbon monoxide, PM2.5, PM10, SO2, ammonia
Pollutants – unwanted chemicals or other material found in the air. Pollutants can harm health, the environment and property. Many air pollutants occur as gases or vapors, but some are very tiny solid particles: dust, smoke, or soot.
Potential to Emit – means the maximum aggregate capacity of a source operation or of a facility to emit an air contaminant under its physical or operational design. Any physical or operational limitation on the capacity of a source operation or a facility to emit an air contaminant, including control apparatus, and restrictions on hours of operation or on the type or amount of material combusted, stored or processed, shall be treated as part of its design if the limitation is federally enforceable. If there is no federally enforceable limitation on the hours of operation of a course operation, then any determination of the maximum design capacity shall be based on a presumption of operation at 8760 hours per year. This term includes the fugitive emissions emitted by the source operation or facility as calculated in a manner consistent with the provisions of N.J.A.C. 7:27-21 and current guidance issued by the Department pursuant thereto.
Precursor – In photochemistry, a compound antecedent to a pollutant. For example, volatile organic compounds (VOCs) and nitrogen oxides react in sunlight to form ozone or other photochemical oxidants. As such, VOCs and oxides of nitrogen are precursors.
Primary Standard – A pollution limit based on health effects. Primary standards are set for criteria air pollutants.
Quality Assurance/Quality Control (QA/QC) – A system of procedures, checks, audits, and corrective actions to ensure that all research design and performance, environmental monitoring and sampling, and other technical and reporting activities achieve the program’s desired data quality objectives.
RACM – means Reasonably Available Control Measure as defined by USEPA in accordance with Section 172(c)(1) of the CAA and subsequent rules and guidance. In general, USEPA interprets the RACM provision to require a demonstration that the state has adopted all reasonable measures (including RACT) to meet RFP requirements and to demonstrate attainment as expeditiously as practicable. They also require an additional analysis to determine if there are any additional RACM that will advance the attainment date by at least one year. They further interpret RACM to mean measures that are technologically and economically feasible, do not cause substantial widespread and long term adverse impact, or are absurd, unenforceable or impracticable.
RACT – means Reasonably Available Control Technology as defined by USEPA in accordance with CAA Sections 184(b)(1) and 184(b)(2).

SIP – means State Implementation Plan. A detailed description of the programs a state will use to carry out its responsibilities under the Clean Air Act. State implementation plans are collections of the regulations used by a state to reduce air pollution in nonattainment areas. The Clean Air Act requires that the USEPA approve each state implementation plan. Members of the public are given opportunities to participate in review and approval of state implementation plans.
SJTPO – means South Jersey Transportation Planning Organization. The SJTPO is the Metropolitan Planning Organization (MPO) serving Atlantic, Cape May, Cumberland, and Salem counties in South Jersey.
Smog – a mixture of pollutants, principally ground-level ozone.
SO2 – means Sulfur Dioxide. A criteria air pollutant. Sulfur dioxide is a gas produced by burning coal, most notably in power plants. Some industrial processes, such as production of paper and smelting of metals, produce sulfur dioxide. Sulfur dioxide is closely related to sulfuric acid, a strong acid. Sulfur dioxide plays an important role in the production of acid rain.
SOx – means Oxides of Sulfur.
Source – any place or object from which pollutant emissions are released. Source air emissions are generally classified into four categories: point stationary sources, area or nonpoint stationary sources, onroad mobile sources and nonroad mobile sources.
Source Gas – means air or gases passed through, or generated by, a source operation and discharged from the source operation.
Source Operation – means any process or any identifiable part thereof that emits or can reasonably be anticipated to emit any air contaminant either directly or indirectly into the outdoor atmosphere. A source operation may include one or more pieces of equipment or control apparatus.
Stage I or Phase I Vapor Recovery System – means a system that controls vapors during the transfer of gasoline from a delivery vessel to a gasoline dispensing facility vessel.
Stage II or Phase II Vapor Recovery System – means a system that controls vapors during the transfer of gasoline from a gasoline dispensing facility vessel to a motor vehicle.
STAPPA – means State and Territorial Air Pollution Program Administrators. A national association of air pollution control agencies throughout the United States
State Implementation Plan (SIP) – A detailed description of the programs a state will use to carry out its responsibilities under the Clean Air Act. State implementation plans are collections of the regulations used by a state to reduce air pollution in nonattainment areas. The Clean Air Act requires that the USEPA approve each state implementation plan. Members of the public are given opportunities to participate in review and approval of state implementation plans.
Stationary Source – a place or object from which pollutants are released and which does not move around. Stationary sources include power plants, gas stations, incinerators, houses etc.
Stratosphere – part of the atmosphere, the gases that encircle the Earth. The stratosphere is a layer of the atmosphere 9-31 miles above the Earth. Ozone in the stratosphere filters out harmful sunrays, including a type of sunlight called ultraviolet B, which has been linked to health and environmental damage.
SULEV – means Super Ultra Low-Emission Vehicle.
Sulfur Dioxide – a criteria air pollutant. Sulfur dioxide is a gas produced by burning coal, most notably in power plants. Some industrial processes, such as production of paper and smelting of metals, produce sulfur dioxide. Sulfur dioxide is closely related to sulfuric acid, a strong acid. Sulfur dioxide plays an important role in the production of acid rain.
TCMs – means Transportation Control Measures. TCMs are projects that are identified in the State Implementation Plan for air quality as providing specific, measurable benefits for air quality improvement.
TDM – means Transportation Demand Management. TDMs are actions to reduce transportation demand.
Toxic air pollutant – as defined for emission statement reporting means any of the substances listed in N.J.A.C. 7:27-21, Appendix 1, Table 1.
tpd – means tons per day.
tpy – means tons per year.
ULEV – means Ultra Low-Emission Vehicle. A motor vehicle which has been certified as not exceeding the applicable standards set forth in N.J.A.C. 7:27-26.4.
USEPA – means United States Environmental Protection Agency.
Ultraviolet B (UVB) – a type of sunlight. The ozone in the stratosphere, high above the Earth, filters out the ultraviolet B rays and keeps them from reaching the Earth. Ultraviolet B exposure has been associated with skin cancer, eye cataracts, and damage to the environment. Thinning of the ozone layer in the stratosphere results in increased amounts of ultraviolet B reaching the Earth.
VISTAS – means Visibility Improvement State and Tribal Association of the Southeast. A collaborative effort of state governments, tribal governments, and various federal agencies established to initiate and coordinate activities associated with the management of regional haze, visibility, and other air quality issues in the Southeastern United States.
VMT – means vehicle miles traveled. One vehicle traveling the distance of one mile equals one VMT. This measure is used to estimate congestion, fuel consumption, and a host of other key transportation-related factors.
Volatile Organic Compound or VOC – means a volatile organic compound as that term is defined by the USEPA at 40 CFR 51.100(s). A VOC per this definition is any compound of carbon (other than carbon monoxide, carbon dioxide, carbonic acid, metallic carbonates, metallic carbides, and ammonium carbonate) which participates in atmospheric photochemical reactions. This term excludes those compounds which the USEPA has excluded from its definition of VOC in the list set forth at 40 CFR 51.100(s).
