C. 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.
"Clear coating" means a coating which lacks color and opacity or is transparent and uses the undercoat as a reflectant base or undertone color.
"Coating application system" means any operation or system where 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.
"Coating applicator" means an apparatus used to apply a surface coating.
"Extreme environmental conditions" means exposure to any one of the following: the weather all of the time, temperatures consistently above 95°C, detergents, scouring, solvents, corrosive atmospheres or similar environmental conditions.
"Extreme performance coatings" means coatings which are required to be used by design specification on products designed for harsh exposure or extreme environmental conditions.
"Flashoff area" means the space between the application area and the oven.
"Miscellaneous metal parts and products" means any part or product from the following industrial categories:
a. Large farm machinery (harvesting, fertilizing and planting machines, tractors, combines, etc.);
b. Small farm machinery (lawn and garden tractors, lawn mowers, rototillers, etc.);
c. Small appliances (fans, mixers, blenders, crock pots, dehumidifiers, vacuum cleaners, etc.);
d. Commercial machinery (computers and auxiliary equipment, typewriters, calculators, vending machines, etc.);
e. Industrial machinery (pumps, compressors, conveyor components, fans, blowers, transformers, etc.);
f. Fabricated metal products (i.e., metal covered doors, frames); and
g. Any other industrial category which coats metal parts or products under the Standard Industrial Classification Code of Major Group 33 (primary metal industries), Major Group 34 (fabricated metal products), Major Group 35 (nonelectrical machinery), Major Group 36 (electrical machinery), Major Group 37 (transportation equipment), Major Group 38 (miscellaneous instruments), Major Group 39 (miscellaneous manufacturing industries), Major Group 40 (railroad transportation), and Major Group 41 (transit passenger transportation). "Major groups" (i.e., which have the same two-digit code) shall be described in the Standard Industrial Classification Manual (see 9VAC5-20-21).
"Oven" means a chamber within which heat is used to bake, cure, polymerize or dry a surface coating or any combination of those.
