(a) For the purpose
				  of this Rule, the following definitions shall apply:
(1) "Cartridge filter" means perforated
				  canisters containing filtration paper or filter paper and activated carbon that
				  are used in a pressurized system to remove solid particles and fugitive dyes
				  from soil-laden solvent, together with the piping and ductwork used in the
				  installation of this device.
(2)
				  "Containers and conveyors of solvent" means piping, ductwork, pumps, storage
				  tanks, and other ancillary equipment that are associated with the installation
				  and operation of washers, dryers, filters, stills, and settling
				  tanks.
(3) "Dry cleaning" means a
				  process for the cleaning of textiles and fabric products in which articles are
				  washed in a non-aqueous solution or solvent and then dried by exposure to a
				  heated air stream.
(4) "Dryer"
				  means a machine used to remove petroleum solvent from articles of clothing or
				  other textile or leather goods, after washing and removing of excess petroleum
				  solvent, together with the piping and ductwork used in the installation of this
				  device.
(5) "Perceptible leaks"
				  means any petroleum solvent vapor or liquid leaks that are visible, such as
				  pools or droplets of liquid, open containers of solvent, or solvent laden waste
				  standing open to the atmosphere, or bubble after application of a soap
				  solution.
(6) "Petroleum solvent"
				  means organic material produced by petroleum distillation comprising of a
				  hydrocarbon range of eight to 12 carbon atoms per organic molecule that exists
				  as a liquid under standard conditions.
(7) "Petroleum solvent dry cleaning" means a
				  dry cleaning facility that uses petroleum solvent in a combination of washers,
				  dryers, filters, stills, and settling tanks.
(8) "Settling tank" means a container that
				  gravimetrically separates oils, grease, and dirt from petroleum solvent,
				  together with the piping and ductwork used in the installation of the
				  device.
(9) "Solvent filter" means
				  a discrete solvent filter unit containing a porous medium which traps and
				  removes contaminants from petroleum solvent, together with the piping and
				  ductwork used in the installation of this device.
(10) "Solvent recovery dryer" means a class
				  of dry cleaning dryers that employs a condenser to condense and recover solvent
				  vapors evaporated in a closed-loop stream of heated air, together with the
				  piping and ductwork used in the installation of this device.
(11) "Still" means a device used to
				  volatilize, separate, and recover petroleum solvent from contaminated solvent,
				  together with the piping and ductwork used in the installation of this
				  device.
(12) "Washer" means a
				  machine that agitates fabric articles in a petroleum solvent bath and spins the
				  articles to remove the solvent, together with the piping and ductwork used in
				  the installation of this device.
