For the purposes of this chapter, the following definitions shall apply unless the context clearly indicates or requires a different meaning.
AIR CONTAMINANT. Any smoke, soot, fly ash, dust, cinders, dirt, noxious, or obnoxious acids, fumes, oxides, gases, vapors, odors, toxic, or radioactive substances, waste, particulate, solid, liquid, or gaseous matter or any other materials in the outdoor atmosphere, but excluding uncombined water.
AIR POLLUTION. The presence in the outdoor atmosphere of one or more contaminants or combinations thereof in quantities and of a 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.
ASHES. Cinders, fly ash, or any other solid material resulting from combustion, and may include unburned combustibles.
ASME. The American Society of Mechanical Engineers.
ASTM. The American Society for Testing Materials.
CERTIFICATE OF OPERATION. A certificate issued by the Director authorizing the use of any process, fuel burning, refuse burning, or control equipment for the period indicated after it has been found that it can be operated in compliance with this chapter.
CLEANING FIRES. Act of removing ashes from the fuel bed or furnace.
COMBUSTIBLE REFUSE. Any combustible waste material.
CONTROL EQUIPMENT. Any equipment which has the function of regulating that portion of a process, fuel burning, or refuse burning equipment which may release air contaminants and thus reduce the creation of or the emission of air contaminants to the atmosphere or both.
DEPARTMENT. The Air Quality Control Department of the city.
DIRECTOR. The Director of the Air Quality Control Department or his or her authorized representatives.
DOMESTIC HEATING PLANT. A plant generating heat for a single-family residence or for two residences, either in duplex or double house form, or for multiple-dwelling units having a total input of less than one million BTUs per hour, provided, that the heating plant is for the single purpose of space heating and the fuel used is gas or light fuel oils. Under this designation are, also, hot water heaters, stoves, space-heaters, and other domestic appliances used in connection with the foregoing establishments or to heat temporary buildings; provided, that similar equipment used in multiple dwelling units other than described in this chapter, or used in permanent buildings of commercial or industrial establishments, is not to be construed as included under this designation.
DOMESTIC INCINERATOR OR REFUSE BURNING EQUIPMENT. Any refuse burning equipment or incinerator which is portable, packaged, completely assembled, and directly fed, having not over five cubic feet storage capacity or 25 pounds per hour burning rate, designed to handle combustible refuse consisting of rubbish and garbage by weight.
EMISSION. The act of passing into the atmosphere of an air contaminant or the material so passed to the atmosphere.
FUEL BURNING EQUIPMENT. Any equipment, device, or contrivance used for the burning of any fuel and all appurtenances thereto, including ducts, breechings, control equipment, fuel feeding equipment, ash removal equipment, combustion controls, stacks, chimneys, and the like, used for indirect heating in which the material being heated is not contacted by and adds no substance to the products of combustion. The EQUIPMENT typically includes that used for heating water to boiling; raising or superheating steam; heating air, as in a warm air furnace; furnishing process heat that is conducted through process vessel walls; and furnishing process heat indirectly through its transfer by fluids.
HAND-FIRED FUEL BURNING EQUIPMENT. Fuel burning equipment in which fuel is manually introduced directly into the combustion chamber.
INCINERATORS. All devices intended or used for the destruction of refuse or other combustible refuse by burning.
INSTALLATION PERMIT. A permit issued by the Director of the Air Quality Control Department authorizing the construction, installation, or alteration of any process, fuel burning, refuse burning, or control equipment in accordance with plans and specifications approved by the Director of the Air Quality Control Department.
OPACITY. State of a substance which renders it partially or wholly impervious to the rays of light. OPACITY as used in this chapter refers to the obscuration of an observer’s view.
OPEN BURNING. Any fire from which the products of combustion are emitted directly into the outdoor atmosphere without passing through a stack.
PARTICULATE MATTER. Material other than uncombined water which is suspended in air or other gases as a liquid or solid.
PROCESS EQUIPMENT. Any equipment, device, or contrivance for changing any materials whatever or for storing or handling of any materials and all appurtenances thereto, including ducts, stacks, and the like, the use or existence of which may cause any discharge of air pollutants into the outdoor atmosphere, but not including that equipment specifically defined as FUEL BURNING EQUIPMENT or REFUSE BURNING EQUIPMENT in this section.
PROCESS WEIGHT. The total weight of all materials introduced into a unit operation or unit process, including solid fuels, but excluding liquid and gaseous fuels when these are used solely as fuels and excluding air introduced for purposes of combustion.
PROCESS WEIGHT RATE. A rate established as follows:
(1) For continuous or long-run, steady-state unit operations or unit process: the total process weight for the entire period of continuous operation or for a typical portion thereof divided by the number of hours of the period or portion thereof;
(2) For cyclical or batch unit operations or unit processes: the total process weight for a period that covers a complete operation or an integral number of cycles divided by the hours of actual process operation during the period; and
(3) Where the nature of any process or operation or the design of any equipment is such as to permit more than one interpretation of this definition, the interpretation that results in the minimum value for allowable emission shall apply.
REFUSE BURNING EQUIPMENT. Any incinerator, equipment, device, or contrivance used for the destruction of refuse or other combustible wastes by burning, and all appurtenances thereto.
SALVAGE OPERATIONS. Any operation conducted in whole or in part for the salvaging or reclaiming of any product or material.
SEAL FOR SEALING EQUIPMENT OR PREMISES. A device installed by the Director of the Air Quality Control Department that prevents use of the process, fuel burning, refuse burning, or control equipment or premises causing the violation or from which violations of this chapter originate.
SMOKE. Small gas borne particles resulting from incomplete combustion, consisting predominantly, but not exclusively, of carbon, ash, and other combustible materials.
STACK. Duct, chimney, flue, conduit, vent, exhaust, breeching, or any structure or opening arranged for the emission into the outdoor atmosphere of air pollutants.
TOTAL PLANT. A facility or installation that is comprised of one or more fuel burning units, incinerators, or processes that are located at a single site or in one enclosure and that is usually served internally by common utilities and control systems, storage equipment, and other related facilities.
UNIT OPERATION. Methods where raw materials undergo physical change; methods by which raw materials may be altered into different states, such as a vapor, liquid, or solid, without changing into a new substance with different properties and composition.
UNIT PROCESS. Reactions where raw materials undergo chemical change; where one or more raw materials are combined and completely changed into a new substance with different properties and composition.
