INTRODUCTION This compilation contains selected sections of many emission control regulations and ordinances. It has been prepared to provide state and local air pollution control agencies, industries, and other interested people with selected examples of the many types of regulations and ordinances in use today. All sections of regulations and ordinances included have been copied directly from the original text of individual state and local laws. The regulations and ordinances have been arranged in such a manner that each section of this report is a compilation of laws pertaining to a specific type of pollutant or pollutant source. These sections include Smoke Emissions and Equivalent Opacity Regulations, Regulations Pertaining to Particulate Emissions from Fuel Burning Plants, Regulations Pertaining to Particulate Emissions from Refuse-Burning Equipment, Regulations Pertaining to Particulate Emissions from Manufacturing Processes, Regulations Pertaining to Sulfur Compound Emission Control, Regulations Pertaining to Hydrocarbon Emission Control, Regulations Pertaining to Fluoride Emission Control, Regulations Pertaining to Motor Vehicle Emission Control, Regulations Pertaining to Odor Emission Control, and Zoning Ordinances. The regulations and ordinances compiled were selected to represent the different methods of controlling emissions by law and to represent varying degrees of control. The definitions used were for the most part taken directly from existing regulations and ordinances. Some were picked selectively to provide what we feel are very good definitions while others were picked because of their wide use by many states and communities. DEFINITIONS TYPICALLY INCLUDED IN AIR POLLUTION ORDINANCES (1) Aerosol. A dispersion or any suspension of small solid or liquid particles or any combination thereof in the air or other gaseous medium. (2) Ashes. Includes cinders, fly ash or any other solid material resulting from combustion, and may include unburned combustibles. (3) ASME. The American Society of Mechanical Engineers. (4) ASTM. The American Society for Testing Materials. (5) Air Contaminant. Any smoke, soot, fly ash, dust, cinders, dirt, noxious or obnoxious acids, fumes, oxides, gases, vapors, odors, toxic or radioactive substance, waste, particulate, solid, liquid or gaseous matter, or any other materials in the outdoor atmosphere. (6) Air Pollution. The presence in the outdoor atmosphere of one or more air contaminants or combinations thereof in such quantities and of such duration that they are or may tend to be injurious to human, plant, or animal life, or property, or that interfere with the comfortable enjoyment of life or property or the conduct of business. Where (7) Atmosphere. The air that envelops or surrounds the earth. air pollutants are emitted into a building not designed specifically as a piece of air pollution control equipment, such emission into the building shall be considered an emission into the atmosphere. (8) Cinders. Particles not ordinarily considered as fly ash or dust because of their greater size, consisting essentially of fused ash and/ or unburned matter. (9) Cleaning Fires. The act of removing ashes from the fuel bed or furnace. (10) Combustion Contaminants. Particulate matter discharged into the atmosphere from the burning of any kind of material containing carbon in a free or combined state. (11) Combustible Refuse. Any combustible waste material containing carbon in a free or combined state other than liquids or gases. (12) Condensed Fumes. Minute solid particles generated by the condensation of vapors from solid matter after volatilization from the molten state, or generated by sublimation, distillation, calcination, or chemical reaction when these processes create airborne particles. (13) Domestic Refuse-Burning Equipment. Any refuse-burning equipment or incinerator used for a single family residence, or for two residences either in duplex or double house form, or for multiple-dwelling units in which such equipment or incinerator serves fewer than three apartments. (14) Dusts. Minute solid particles released into the air by natural forces or by mechanical processes such as crushing, grinding, milling, drilling, demolishing, shoveling, conveying, covering, bagging, sweeping, etc. (15) Dust-Separating Equipment. Any device for separating dust from the air or gas medium in which it is carried. (16) Fly Ash. Particulate matter capable of being gas-borne or airborne and consisting essentially of fused ash and/or burned or unburned material. (17) Fuel. Any form of combustible matter - solid, liquid, vapor, or gas excluding combustible refuse. (18) Fuel-Burning or Combustion Equipment or Device. Any furnace, fuel-burning equipment, or boiler used for the burning of fuel, or for the emission of products of combustion, or used in connection with any process which generates heat and may emit products of combustion. (19) Fuel-Burning Equipment, Mechanical. Any fuel-burning or combustion equipment or device incorporating a device by means of which fuel is mechanically introduced from outside the furnace into the zone of combustion. (20) Furnace. An enclosed space provided for the ignition and/or combustion of fuel. (21) Incinerators. All devices intended or used for the destruction of garbage or other combustible refuse by burning. (22) Low Volatile Solid Fuel. A solid fuel, the volatile content of which is 23% or less on an ash free and moisture free basis. (23) Mist. A suspension of any finely-divided liquid in any gas or atmosphere. (24) Multiple-Chamber Incinerator. Any article, machine, equipment, contrivance, structure or part of a structure, used to dispose of combustible refuse by burning, consisting of three or more refractory lined combustion furnaces in series, physically separated by refractory walls, interconnected by gas passage ports or ducts and employing adequate design parameters necessary for maximum combustion of the material to be burned. The refractories shall have a Pyrometric Cone Equivalent of at least 17, tested according to the method described in the American Society for Testing Materials, Method C-24. |
