As used in this chapter:
(1) "Air-cleaning equipment" means any control equipment which removes, reduces or renders less noxious air contaminants discharged into the atmosphere.
(2) "Air contaminant" means any solid, liquid or gas, or any combination thereof except uncombined water, discharged into the atmosphere.
(3) "Air pollution" means the presence in the atmosphere of one or more air contaminants in such quantities for such period of time that they are, or may be, injurious to human, plant or animal life or to property or that they interfere with the comfortable enjoyment of life or property or with the conduct of business.
(4) "Appeals Board" means the Board of Building Code Appeals or any subsequent appeals board established by ordinance and vested with jurisdiction in matters relating to air pollution.
(5) "A.S.M.E." means the American Society of Mechanical Engineers.
(6) "A.S.T.M." means the American Society for Testing Materials.
(7) "Atmosphere" means the air that envelops or surrounds the earth.
(8) "B.T.U." or "British Thermal Unit" means the amount of heat required to raise one pound of water one degree Fahrenheit.
(9) "Control equipment" means any equipment designed to regulate the release of contaminants from any process, fuel-burning or refuse-burning equipment by reducing the creation of air contaminants or the emission of air contaminants into the atmosphere, or both.
(10) "Emission" means the act of releasing air contaminants into the atmosphere, or the material so released.
(11) "Fuel" means any form of combustible matter, whether solid, liquid or gas, but does not include refuse.
(12) "Fuel-burning equipment" means any furnace, boiler apparatus or stack, and any appurtenance thereto, used in the process of burning fuel for the primary purpose of producing heat or power.
(13) "Odor" means that property of an air contaminant which affects the sense of smell.
(14) "Opacity" means that state of a substance which renders it partially or wholly impervious to light rays and refers to the obscuration of an observer's view.
(15) "Open fire" means a fire from which the products of combustion are emitted directly into the open air without passage through a stack or chimney.
(16) "Particulate matter" means material, other than uncombined water, which is suspended in or discharged into the atmosphere in a finely divided form as a liquid or solid, at standard conditions.
(17) "Person" means any individual, partnership, partner, firm, company, corporation, association, joint stock company, trust, estate, governmental entity or other legal entity, and any legal representative, agent or assign thereof.
(18) "Process equipment" means any equipment, device or contrivance, and any appurtenance thereto, including ducts and stacks, used for changing, storing or handling any materials, the use of which equipment may cause the discharge of an air contaminant into the atmosphere, but does not include that equipment specifically defined in this Air Pollution Code as fuel- burning or refuse-burning equipment.
(19) "Process weight" means the total weight of all material introduced into a unit operation or unit process, including solid fuels, but not including liquid or gaseous fuels used solely as fuels or air introduced for purposes of combustion.
(20) "Process weight per hour" means a rate established as follows:
(a) For a continuous or long-run steady-state unit operation 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 such period or portion thereof; and
(b) For a cyclical or batch unit operation or batch process, the total process weight for a period that covers a complete operation or an integral number of cycles divided by the number of hours of actual process operation during such period.
When the nature of any process or operation or the design of any equipment is such as to permit more than one interpretation of the definition provided herein, the interpretation that results in the minimum value for permitted emission shall apply.
(21) "Refuse-burning equipment" means any incinerator, equipment, device or contrivance, and any appurtenance thereto, used for destroying garbage or other combustible wastes by burning.
(22) "Ringelmann Chart" means that chart published and described in the U. S. Bureau of Mines Information Circular 8333, on which Chart are illustrated graduated shades from grey to black for use in estimating the light-obscur ing capacity of smoke.
(23) "Seal for sealing equipment or premises" means any device, tag or marking installed or affixed by the Commissioner of Air Pollution Control or his agents or representatives so as to prevent the use of the process, fuel- burning, refuse-burning or control equipment or of the premises causing a violation or from which violations of this Air Pollution Code originate.
(24) "Smoke" means small gas-borne particles resulting from incomplete combustion and consisting predominantly, but not exclusively, of carbon, ash and other combustible material.
(25) "Stack" means a duct, chimney, flue, conduit, vent or opening designed or arranged for the emission into the atmosphere of air contaminants.
(26) "Standard conditions" means a gas temperature of sixty degrees Fahrenheit and a gas pressure of 14.7 pounds per square inch of absolutely dry air.
(27) "Unit operation" means a method by which raw materials undergo physical change or may be altered into different states, such as vapor, liquid or solid, without changing into a new substance with different properties or composition.
(28) "Unit process" means a reaction by which raw materials undergo chemical change or by which one or more raw materials are combined and changed into a new substance with different properties or composition.
