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

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

"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.
