This rule applies to all persons owning or operating a dry cleaning facility using solvent other than perchloroethylene.
For the purposes of this rule, the following definitions shall apply:
(1) CARTRIDGE FILTER means a replaceable perforated canister that contains paper, activated carbon, or a combination of paper and activated carbon and that is used in a pressurized system in conjunction with piping and ductwork, to trap and remove contaminants such as solid particles and fugitive dyes from soil-laden solvent. 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.
(2) CLOSED-LOOP MACHINE means dry cleaning equipment in which washing, extraction, and drying are performed in the same single unit and which re-circulates and recovers the solvent-laden vapor.
(3) CONDENSER means a closed-loop vapor recovery system into which solvent vapors are introduced and trapped by using a chilling system, with or without refrigeration, to cool the outlet temperature.
(4) COOL DOWN means the portion of the drying cycle that begins when the heating mechanism deactivates and a condenser, chilling coils or some other cooling device activates to reduce the temperature of the air re-circulating through the drum to reduce the concentration of solvent in the drum.
(5) DIP TANK means a vessel or container that is separate from dry cleaning equipment, in which materials are immersed in solution that contains solvent for purposes other than dry cleaning.
(6) DISTILLATION UNIT OR STILL means a device used to volatilize, separate and recover solvent from contaminated solvent.
(7) DISTRICT is as defined in Rule 102.
(8) DRUM means the rotating cylinder or wheel of the dry cleaning machine that holds the materials being cleaned, extracted or dried.
(9) DRYING CABINET means a separate housing unit from the washer or extractor, to which wet, solvent-laden materials, that would otherwise be damaged by the heat and tumbling action of the drying cycle are transferred for drying.
(10) DRYING CYCLE means the process used to actively remove the solvent remaining in the materials after washing and extraction. The drying cycle begins when heating coils are activated and ends when the machine ceases rotation of the drum. For closed-loop machines, the heated portion of the drying cycle is followed by cool down.
(11) EXEMPT COMPOUNDS are defined in Rule 102.
(12) Gallons of SOLVENT used means the volume of solvent, in gallons, introduced into the dry cleaning equipment, and not recovered at the facility for re-use on-site in the dry cleaning equipment, over a specified time period.

(16) non-Halogenated hydrocarbon detector means a portable device capable of detecting vapor concentrations of solvent of 250 ppm by volume or less and indicating an increasing concentration by emitting an audible signal or visual indicator that varies as the concentration changes.
(17) PORTABLE HYDROCARBON ANALYZER means a portable device which uses the flame ionization detection or thermal conductivity methods and satisfies EPA Method 21, 40 CFR Part 60, to analyze hydrocarbon vapor concentrations. The instrument shall be equated to calibrating on methane and sampling at one liter per minute.
(18) PRE-WASH WEIGHT OF MATERIALS CLEANED PER LOAD means the total dry weight, in pounds, of the materials in each load dry cleaned at the facility, as determined by weighing each load on a scale prior to dry cleaning.
(19) SETTLING TANK means a container which gravimetrically separates oils, grease, dirt and any other contaminants from solvent.
(20) SOLVENT, for the purpose of this rule only, means a substance, including any detergents and additives, containing volatile organic compounds (VOC) or Group II exempt compound other than perchloroethylene that is used to dry clean materials and that exists as a liquid under standard conditions.
(21) SOLVENT DRY CLEANING EQUIPMENT OR DRY CLEANING EQUIPMENT means any machine, device, or apparatus used to dry clean materials with solvent or to remove residual solvents from previously cleaned materials. Dry cleaning equipment may include, but is not limited to, a transfer machine, a closed-loop machine, a solvent recovery dryer, washer tumblers, extractors, dryers, reclaimers, condensers, chillers, heating coils, chilling coils, filters, purification systems, settling tanks, separators, stills, waste disposal systems, holding tanks, pumps, flanges, valves and associated piping.

(25) SOLVENT RECOVERY DRYER, DRYER, RECLAIMER, OR RECLAIMER DRYER is a class of dry cleaning dryers that employs a condenser or other cooling device to liquefy and recover solvent vapors evaporated in a closed-loop, re-circulating stream of air.
(26) SPIN-DISC FILTER means a filter that traps and removes contaminants such as solid particles and fugitive dyes from soil-laden solvent and that can be cleaned, regenerated, and reused in closed-loop machines.
(27) TRANSFER CART is a cart or container used for the transfer of wet solvent-laden materials from the washer to the dryer or to the drying cabinet that has a lid and walls which are impervious to the solvent.
(28) TRANSFER MACHINE means a combination of solvent dry cleaning equipment in which washing and extraction are performed in one unit and drying is performed in a separate unit.
(29) VAPOR LEAK means an emission of solvent vapor from openings in the dry cleaning equipment which causes bubbling from the application of a soap solution, causes a portable analyzer to exceed 250 ppm as methane, as determined by EPA Method 21, or causes a non-halogenated hydrocarbon detector to emit an audible signal or visual signal.
