For the purpose 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, injurious or objectionable acids, fumes, oxides, gases, vapors, odors, toxic or radioactive substances, waste, particulate, solid, liquid or gaseous matter, or any other material in the outdoor atmosphere, but excluding uncombined water.
AIR POLLUTION. The presence in the outdoor atmosphere of 1 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, property or the conduct of business.
AIR POLLUTION CONTROL BOARD. The Board created by this chapter and described more specifically in §§ 34.015 through 34.021.
ASHES. Includes 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.
BOARD. The Air Pollution Control Board.
CERTIFICATE OF OPERATION. A certificate issued by the Chief 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.
CHIEF. The CHIEF of the Department of Air Pollution Control of the city or his or her authorized representative, as described more specifically in § 34.036.
CLEANING FIRES. The 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 contaminants and thus reduce the creation of or the emission of air contaminants to the atmosphere or both.
DOMESTIC HEATING PLANT. A plant generating heat for a single-family residence or for 2 residences either in duplex or double house form or for multiple-dwelling units having a total input of less than 1,000,000 BTUs per hour. Under this designation are also hot water heaters, stoves and space heaters used in connection with the foregoing establishments, or to heat temporary buildings. Similar equipment used in multiple-dwelling units other than herein described or used in permanent buildings of commercial or industrial establishments is not to be construed as included under this designation.
DOMESTIC INCINERATOR. Portable, packaged, completely assembled, directly fed incinerator, having not over 5 cubic feet storage capacity or 25 pounds per hour burning rate, which is designed to handle combustible refuse consisting of approximately equal amounts of rubbish and garbage by weight.
EMISSION. The act of passing into the atmosphere of 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. This equipment typically includes that used for heating water to boiling, raising steam or super heating 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.
INSTALLATION PERMIT. A permit issued by the Chief authorizing the construction, installation or alteration of any process, fuel burning, refuse burning or control equipment in accordance with the plans and specifications approved by the Chief.
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 similar appurtenances, 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 chapter.
PROCESS WEIGHT. The total weight of all material introduced into a unit operation or unit process, including solid fuels, but excluding liquid fuels 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 described below.
(1) For continuous or long run steady state unit operations or unit processes, the total process weight for the entire period of continuous operation or for a typical portion thereof, divided by the number of hours of that 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 operations during that period.
(3) Where the nature of any process or operation or the design of any equipment permits more than 1 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 Chief so as to prevent 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 material.
STACK. Duct, chimney, flue, conduit or opening arranged for the emission into the outdoor atmosphere of air pollutants.
UNIT OPERATION. Methods where raw materials undergo physical change or methods by which raw materials may be altered into different states, such as vapor, liquid or solid, without changing into a new substance with different properties and composition.
UNIT PROCESS. Reactions where raw materials undergo chemical change or where 1 or more raw materials are combined and completely changed into a new substance with different properties and composition.
