"Desorption" means regeneration of a carbon adsorber
				by removal of the perchloroethylene adsorbed on the carbon.
I.
Diverter valve.
"Diverter
				valve" means a flow control device that prevents room air from passing through
				a refrigerated condenser when the door of the dry-cleaning machine is
				open.
J.
Dry cleaner.
"Dry cleaner" means a facility engaged in the cleaning of garments in
				perchloroethylene by means of one or more washes in the solvent, extraction of
				the solvent by spinning, and drying by tumbling in an air stream. The facility
				includes, but is not limited to any washer, dryer, emission control device(s),
				exhaust dampers, diverter valves, filter purification system, waste disposal
				system, stills, holding tank, muck cooker, water separators, filters, solvent
				containers, pump and attendant piping, hoses, ducts and valves.
K.
Dry-cleaning drum.
"Dry-cleaning drum" means the perforated container inside the dry-cleaning
				machine that holds the articles during dry-cleaning.
L.
Dry cleaning system.
"Dry
				cleaning system" means a dry cleaning machine and its ancillary
				equipment.
M.
Dryer.
"Dryer" means a machine used to remove perchloroethylene from articles by
				tumbling them in a heated air stream.
N.
Dry-to-dry machine.
"Dry-to-dry machine" means a one-machine dry cleaning operation in which
				washing and drying are performed in the same machine.
O.
Exhaust damper.
"Exhaust
				damper" means a flow control device that prevents the air-perchloroethylene
				gas-vapor stream from exiting the dry-cleaning machine into a carbon adsorber
				before room air is drawn into the dry-cleaning machine.
P.
Filter.
"Filter" means a
				porous device through which perchloroethylene is passed to remove contaminants
				in suspension. Examples include, but are not limited to, lint filter (button
				trap), cartridge filter, tubular filter, regenerative filter, prefilter,
				polishing filter, and spin disc filter.
Q.
Garment.
"Garment" means any
				article placed in the washer for purposes of cleaning that article.
R.
Halogenated hydrocarbon
				detector.
"Halogenated hydrocarbon detector" means a portable device
				capable of detecting vapor concentrations of perchloroethylene of 25 parts per
				million by volume and indicating a concentration of 25 parts per million by
				volume or greater by emitting an audible or visual signal that varies as the
				concentration changes.
S.
Heating coil.
"Heating coil" means the device used to heat the air
				stream circulated from the dry cleaning machine drum, after perchloroethylene
				has been condensed from the air stream and before the stream re-enters the dry
				cleaning machine drum.
T.
Major Source.
"Major source" means a source whose twelve-month
				rolling total consumption of perchloroethylene exceeds 2100 gallons.
U.
Muck cooker.
"Muck cooker"
				means a device for heating perchloroethylene-laden waste material to volatilize
				and recover perchloroethylene.
V.
Perchloroethylene or perc or tetrachloroethylene or PCE.
"Perchloroethylene" or "perc" or "tetrachloroethylene" or "PCE" means a
				colorless volatile chlorinated hydrocarbon with a chemical formula of C2Cl4 and
				a CAS (Chemical Abstract System) Registry number of 127-18-4.
W.
Perchloroethylene
				consumption
. "Perchloroethylene consumption" means the twelve-month
				rolling total volume (sum) of perchloroethylene purchased based upon monthly
				purchase receipts or other reliable measures.
X.
Perchloroethylene Consumption
				Limit.
"Perchloroethylene consumption limit" means a dry-cleaner's
				highest twelve-month rolling total perchloroethylene consumption, as calculated
				according to subsection
				6(A)(2).
Y.
Perchloroethylene gas analyzer or
				PCE gas analyzer.
"Perchloroethylene gas analyzer" or "PCE gas
				analyzer"means a flame ionization detector, photoionization detector, or
				infrared analyzer capable of detecting vapor concentrations of
