As used in this chapter, the following terms shall have the meanings respectively ascribed to them:
(a) "Air contaminant" means smoke, charred paper, dust, soot, grime, carbon, noxious acids, fumes, gases, mist, odors or particulate matter, or any combination thereof.
(b) "Air pollution abatement operation" means any operation which has as its essential purpose a significant reduction in the emission of air contaminants or the effect of such emission.
(c) "Atmosphere" means the air that surrounds the earth and includes the general volume of gases contained within any building or structure, but excludes both:
(1) The gases contained in any building or structure specifically designed for and used as part of an air pollution abatement operation or in a piece of processing or operating equipment, or in any building from which no significant portion of the air contaminants contained therein escapes; and
(2) The gases travelling from a source operation to a collection system, provided such collection system collects the air contaminants discharged by such source operation to such a degree that no significant portion thereof escapes collection.
(d) "Combustion" means the rapid exothermic reaction of any material with oxygen.
(e) "Combustion device" means any furnace, incinerator, refuse-burning equipment, boiler, fly ash collector, apparatus, device, mechanism, stack, chimney or structure used for the burning of fuel or other combustible material, or for the emission of products of combustion or used in connection with processes which generate or utilize heat and may emit products of combustion, and includes process furnaces, stills, cupolas, kilns, direct or indirect fired dryers and core baking ovens.
(f) "Emission" means the act of passing into the atmosphere an air contaminant or a gas stream which contains or may contain an air contaminant, or the material so passed to the atmosphere.
(g) "Emission point" means the location (place in horizontal plane and vertical elevation) at which an emission enters the atmosphere.
(h) "Exhaust gas volume" means the total volume of gases emitted from an emission point.
(i) "Particulate matter" means any material which is emitted as liquid or solid particles, or both of such, but excludes uncombined water. For the purpose of this subsection, material emitted at any temperature in excess of 500 degrees Fahrenheit may be deemed to have been emitted at 500 degrees Fahrenheit.
(j) "Person" means any natural person, corporation, government agency, public officer, association, joint venture, partnership or any combination of such jointly or separately, operating in concert for any common objective related to the purposes of this regulation. It includes the owner, lessor, lessee, tenant, licensee, manager and operator, or any of such, of any emission point or any source operation related thereto, or of any interest in such emission point or source operation.
(k) "Source gas volume" means the volume, in standard cubic feet, of all gases leaving a source operation. For purposes of this subsection, the boundary of a source operation is that point or surface at which the separation of the air contaminants from the process materials, or the conversion of the process materials into air contaminants, is essentially complete.
(l) "Source operation" means the last operation preceding the emission of an air contaminant, which operation:
(1) Results in the separation of the air contaminant from the process materials, or in the conversion of the process materials into air contaminants, as in the case of combustion of fuel, and
(2) Is not an air pollution abatement operation.
(m) "Standard conditions" means a pressure of 14.7 pounds per square inch, absolute, and a temperature of sixty degrees Fahrenheit.
(n) "Standard cubic foot of a gas" means that amount of the gas which would occupy a cube having dimensions of one foot on each side, if the gas were at standard conditions. Calculations to determine the number of standard cubic feet corresponding to actual measured conditions shall follow accepted engineering practice.
(o) "Standard dry cubic foot of a gas" means that amount of the gas which would occupy a cube having dimensions of one foot on each side, if the gas were free of water vapor and at standard conditions. Calculations to determine the number of standard dry cubic feet corresponding to actual measured conditions shall follow accepted engineering practice.
