CAA – means Clean Air Act. The Federal Clean Air Act, 42 U.S.C. §§ 7401 et seq., as amended and supplemented. The original Clean Air Act was passed in 1963, but our national air pollution control program is actually based on the 1970 version of the law. The 1990 Clean Air Act Amendments are the most far-reaching revisions of the 1970 law. In this summary, we refer to the 1990 amendments as the 1990 Clean Air Act.

CAIR – means Clean Air Interstate Rule. CAIR will permanently cap emissions of sulfur dioxide (SO2) and nitrogen oxides (NOx) in the eastern United States.

CAMR – means Clean Air Mercury Rule. The USEPA issued the Clean Air Mercury Rule to permanently cap and reduce mercury emissions from coal-fired power plants.

CARB – means California Air Resources Board. The agency or its successor agency established and empowered to regulate sources of air pollution in the State of California, including motor vehicles, pursuant to section 39003, California Health & Safety Code, 1999, as amended or supplemented.

Carbon Dioxide (CO2) – means a colorless, odorless, tasteless gas at standard conditions, having a molecular composition of one carbon atom and two oxygen atoms.

Carbon Monoxide (CO) – A colorless, odorless, tasteless gas at standard conditions, having a molecular composition of one carbon atom and one oxygen atom. CO is produced by incomplete burning of carbon-based fuels: including gasoline, oil and wood.  Carbon monoxide is also produced from incomplete combustion of many natural and synthetic products.

CFR – means the Code of Federal Regulations. The Code of Federal Regulations (CFR) is a codification of the rules published in the Federal Register by Executive departments and agencies of the Federal Government. The CFR is divided into 50 titles which represent broad areas subject to Federal regulation, with environmental regulations contained mainly in title 40. Each volume of the CFR is revised once each calendar year. Title 40 is revised every July 1.

Clean Air Act (CAA) – means the Federal Clean Air Act, 42 U.S.C. §§ 7401 et seq., as amended and supplemented. The original Clean Air Act was passed in 1963, but our national air pollution control program is actually based on the 1970 version of the law. The 1990 Clean Air Act Amendments are the most far-reaching revisions of the 1970 law. In this summary, we refer to the 1990 amendments as the 1990 Clean Air Act.

Cleaner Fuel – means a fuel other than a combustion source’s primary fuel, the combustion of which results in a rate of NOx emissions that is less than the rate of NOx emissions when the primary fuel is combusted, all other circumstances being equal.

CO – means carbon monoxide. A colorless, odorless, tasteless gas at standard conditions, having a molecular composition of one carbon atom and one oxygen atom.  CO is produced by incomplete burning of carbon-based fuels: including gasoline, oil and wood.  Carbon monoxide is also produced from incomplete combustion of many natural and synthetic products.

Combustion Source – means a source operation or item of equipment which combusts fuel.

Combustion Turbine – means an internal combustion engine fueled by liquid or gaseous fuel, in which blades are driven by combustion gases to generate mechanical energy in the form of a rotation shaft that drives an electric generator or other industrial equipment.

Continuous Emission Monitoring Systems (CEMS) – machines, which measure, on a continuous basis, pollutants released by a source. The 1990 Clean Air Act requires continuous emission monitoring systems for certain large sources.

Control Technology, Measure, Apparatus – equipment, processes or actions which prevents or controls the emission of any air contaminant directly or indirectly into the outdoor atmosphere.

Criteria Air Pollutants – means any air contaminant for which a NAAQS has been promulgated under 40 CFR 50 or for which a New Jersey Ambient Air Quality Standard has been promulgated in N.J.A.C. 7:27-13.

CTG – means Control Technique Guidance. EPA documents designed to assist state and local pollution authorities to achieve and maintain air quality standards for certain sources (e.g., organic emissions from solvent metal cleaning known as degreasing) through reasonably available control technologies (RACT).
