(a) For the purpose of this Part, the general definitions of Part 200 apply.
(b) For the purpose of this Part, the following definitions shall also apply:
(1) Adsorptive cartridge filter. A replaceable cartridge filter that contains diatomaceous earth or activated clay as the filter medium.
(2) Ancillary equipment. The equipment used with a dry cleaning machine in a dry cleaning system including, but not limited to, emission control devices, pumps, filters, muck cookers, stills, solvent tanks, solvent containers, water separators, exhaust dampers, diverter valves, interconnecting piping, hoses and ducts.
(3) Articles. Clothing, garments, textiles, fabrics, leather goods, and the like, that are dry cleaned.
(4) Azeotropic control device. A dry cleaning control system where the vapor stream from the dry cleaning machine drum is first cooled and condensed to reduce the concentration of perc in the vapor stream, and is then treated with water to further enhance the displacement of perc from the articles when the vapor stream is returned to the machine drum. There is no exhaust to the atmosphere during the drying cycle.
(5) Carbon adsorber. An air cleaning device that consists of an inlet for exhaust gases from a dry cleaning machine; activated carbon in the form of a fixed bed, cartridge, or canister, as an adsorbent; an outlet for exhaust gases; and a system to regenerate, or reclaim saturated adsorbent.
(6) Cartridge filter. A replaceable cartridge filter that contains one of the following as the filter medium: paper, activated carbon, or paper and activated carbon. A cartridge filter contains no diatomaceous earth or activated clay. Cartridge filters include, but are not limited to: standard filters, split filters, “jumbo” filters, and all carbon polishing filters.
(7) Closed-loop machine. Dry cleaning equipment in which washing, extraction, and drying are all performed in the same single unit (also known as a dry-to-dry unit) and which recirculates perc-laden vapor through a primary control system (e.g., refrigerated condenser) with no exhaust to the atmosphere during the drying cycle. A closed-loop machine may allow for venting to the ambient air through a local exhaust ventilation system, such as a door fan, after the drying cycle is complete and only while the machine door is open.
(8) Co-located. Sharing a common wall, floor, or ceiling with a residence or business.
(9) Colorimetric detector tube. A glass tube (sealed prior to use), containing material impregnated with a chemical that is sensitive to perc and is designed to measure the concentration of perc in air.
(10) Commercial building. Any building where only commercial business is conducted, such as an office building or strip mall.
(11) Condenser. An air cleaning device that removes condensable vapors by a reduction in the temperature of the exhaust gases or, in the case of a surface condenser, by contact of the exhaust gases with structures that are cooled by a circulating cooling fluid.
(12) Converted machine. An existing vented machine that has been modified to be a closed-loop machine by eliminating the aeration step, installing a primary control system, and providing for recirculation of the perc-laden vapor with no exhaust to the atmosphere or workroom during the drying cycle. A converted machine may allow for venting to the ambient air through a local exhaust ventilation system, such as a door fan, after the drying cycle is complete and only while the machine door is open.
(13) Cool-down. The portion of the drying cycle that begins when the heating mechanism deactivates and the refrigerated condenser continues to reduce the temperature of the air recirculating through the drum to reduce the concentration of perc in the drum.
(14) Desorption. Regeneration or stripping of an activated carbon bed, or any other type of vapor adsorber by removal of the adsorbed solvent using hot air, steam, or other means.
(15) Dip tank. A separate tank that contains perc and is used for purposes other than dry cleaning (e.g., waterproofing).

(24) Drying cabinet. A housing in which materials that have been previously dry cleaned in perc are dried instead of being dried by tumbling in a dry cleaning machine.
(25) Drying cycle. The operation used to actively remove the perc remaining in the materials after washing and extraction. For closed-loop machines, the heated portion of the cycle is followed by cool-down and may be extended beyond cool-down by the activation of a control system. The drying cycle begins when heating coils are activated and ends when the machine ceases rotation of the drum.
(26) Drying sensor. A device that senses when articles being cleaned are relatively dry and automatically controls the drying cycle. Drying sensors include but are not limited to: infrared analyzers, float switches, and resistance probes.
