					 Terms defined.
"Application area" means the area where the coating is
						applied by spraying, dipping or flow coating techniques.
"Carbon adsorption system" means a device containing
						activated carbon as the adsorbent material, an inlet and outlet for exhaust
						gases, and a system to regenerate the saturated adsorbent. The carbon
						adsorption system must provide for the proper disposal or reuse of all volatile
						organic compounds in the adsorbate.
"Coating applicator" means an apparatus used to apply a
						surface coating.
"Coating application system" means any operation or
						system wherein a surface coating of one type or function is applied, dried or
						cured and which is subject to the same emission standard. May include any
						equipment which applies, conveys, dries or cures a surface coating, including,
						but not limited to, spray booths, flow coaters, flashoff areas, air dryers,
						drying areas and ovens. It is not necessary for a coating application system to
						have an oven, flashoff area or drying area to be included in this
						definition.
"Fabric coating" means the coating of a textile
						substrate by knife, roll or rotogravure coating to impart properties that are
						not initially present, such as strength, stability, water or acid repellency,
						or appearance.
"Flashoff area" means the space between the application
						area and the oven.
"Knife coating" means the application of a coating
						material to a substrate by means of drawing the substrate beneath a knife that
						spreads the coating evenly over the full width of the substrate.
"Oven" means a chamber within which heat is used to
						bake, cure, polymerize or dry a surface coating or any combination of
						those.
"Paper coating" means the coating of paper and pressure
						sensitive tapes regardless of substrate by knife, roll or rotogravure coating.
						Related wet coating process on plastic films and decorative coatings on metal
						foil are included in this definition.
"Roll coating" means the application of a coating
						material to a substrate by means of hard rubber or metal rolls.
"Rotogravure coating" means the application of a coating
						material to a substrate by means of a roll coating technique in which the
						pattern to be applied is etched on the coating roll. The coating material is
						picked up in these recessed areas and is transferred to the
						substrate.
