   "Air pollution" means the presence in the outdoor atmosphere of any air contaminants that (1) endanger the health, safety or welfare of the public; (2) cause or may cause injury, detriment, nuisance or annoyance to the public or damage to business or property; or (3) leave the premises on which they originated so as to interfere with the reasonable and comfortable use and enjoyment of property.
   "Automobile or truck sales lot" means any land area used or intended to be used for the display or sale of passenger automobiles or commercial vehicles.
   "Combustion equipment" means any equipment or device which generates heat or energy by burning solid, liquid, or gaseous fuel or other material, and which emits or has the potential to emit air contaminants. Combustion equipment includes, but is not limited to, boilers, furnaces, ovens, incinerators, and generators.
   "Dwelling unit" means a single unit of a building providing complete, independent living facilities for one or more persons, including permanent provisions for living, sleeping, eating, cooking, and sanitation.
   "Equipment" shall have the meaning ascribed to the term "process equipment."
   "Emission source" means any and all sources of air pollution, whether privately or publicly owned or operated. Emission source includes, but is not limited to, all types of business, commercial and industrial plants, work shops and stores, and power plants and stations, buildings and other structures of all types, including multiple-family residences, apartment houses, office buildings, hotels, restaurants, schools, hospitals, churches and other institutional buildings, automobiles, trucks, construction equipment, underground or above ground storage tanks, tractors, buses and other motor vehicles, garages, vending and service locations or stations, railroad locomotives, ships, boats and other waterborne craft, portable fuel-burning equipment, refuse dumps and piles and all stacks, vents and other chimney outlets from any of the foregoing.
   "Emission unit" means any part or activity at a stationary source that emits or has the potential to emit any air pollution.
   "Facility" means any commercial, industrial, or residential establishment which contains one or more regulated areas or units of regulated equipment. A facility may consist of more than one building or structure where all lots are contiguous and the parts of the facility are functionally related.
   "Fumes" means gases, vapors or particulate matter that are of such character as to cause air pollution.
   "Open burning" means the combustion of any matter in such a way that the products of the combustion are emitted into the open air without originating in or passing through equipment for which a permit could be issued under Section 9(b) of the Illinois Environmental Protection Act, as amended.
   "Particulate matter" means material, other than water, which is suspended in or discharged into the atmosphere in finely divided form as a liquid or solid.
   "Pollution control device" means any equipment or device used to eliminate, prevent, reduce or control the emission of air contaminants to the outdoor atmosphere. Pollution control devices include, but are not limited to, scrubbers, dust collectors, thermal oxidizers, cyclones, mist collectors, catalytic converters, and electrostatic precipitators.
   "Process area" means any location within a facility where chemical, industrial, commercial, or manufacturing operations are conducted, and which emits or has the potential to emit air contaminants. Activities conducted in a process area include, but are not limited to, motor vehicle repairs, grinding, sawing, sanding, cutting, buffing, packaging, assembling, machining, blending, coating, plating, or mixing.
   "Process equipment" means any equipment or device used in any industrial, commercial, or manufacturing operations for the mechanical, thermal, or chemical treatment or processing of a raw material, product, or byproduct, and which emits or has the potential to emit air contaminants. Process equipment includes, but is not limited to, tanks, kettles, converters, CNC machines, kilns, ovens, non-residential food preparation units vented to the outdoor atmosphere via a hood, crucibles, stills, dryers, roasters, crushers, grinders, blenders, mixers, reactors, regenerators, separators, filters, spray booths, columns, classifiers, screeners, quenchers, cookers, washers, scrubbers, mills, condensers, absorbers, balers, compactors, unfired pressure vessels, indirect fired vessels, unit heaters, infra red heaters, makeup air units with heating elements, agitators, and sedimentation and classification devices. Process equipment also includes, but is not limited to, equipment or devices required for water conditioning, treatment of industrial and municipal wastes, metallurgical processing, pulp and paper production, food processing, dry cleaning, petrochemical production and other similar operations.
   "Regulated equipment or area" means any combustion equipment, pollution control device, process equipment, or process area.
   "Residential heating plant" means equipment that generates heat, including, but not limited to, hot water heaters, furnaces, stoves, and space heaters, for a dwelling unit, a sleeping unit, or a residential building containing three or fewer dwelling units or sleeping units, or shacks and other temporary buildings, including those used by the railroad and construction industries.
   "Sleeping unit" means a single unit of a building that provides rooms or spaces for one or more persons, includes permanent provisions for sleeping and can include provisions for living, eating, and either sanitation or kitchen facilities but not both. Such rooms and spaces that are part of a dwelling unit occupied by a single household are not sleeping units.
   "Smoke" means small gas-borne particles other than water that form a visible plume in the air from any emission source.
   "Stage II vapor recovery system" means a system for gasoline vapor recovery from the fueling of motor vehicles.
   "Stationary emission source" means an emission source which is not self-propelled.
