A. For the purpose of these regulations and subsequent amendments or any orders issued by the 

board, the words or terms shall have the meanings given them in subsection C of this section. 

B. As used in this article, all terms not defined here shall have the meanings given them in 9VAC5 

Chapter 10 (9VAC5-10-10 et seq.), unless otherwise required by context. 

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.

d. Commercial machinery (computers and auxiliary equipment, typewriters, calculators, vending 

machines, etc.); 

e. Industrial machinery (pumps, compressors, conveyor components, fans, blowers, transformers,

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

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).

9VAC5-40-4780. Standard for volatile organic compounds. 

A. No owner or other person shall cause or permit the discharge into the atmosphere from a coating 

application system any volatile organic compound in excess of: 

1. 4.3 pounds per gallon of coating, excluding water, delivered to the coating applicator that applies 

clear coatings;

application system that utilizes air or forced air driers; 

3. 3.5 pounds per gallon of coating, excluding water, delivered to a coating applicator that applies 

extreme performance coatings, or 

4. 3.0 pounds per gallon of coating, excluding water, delivered to a coating applicator for all other 

coatings and coating application systems. 

B. If more than one emission limitation in subsection A of this section applies to a specific coating, 

then the least stringent emission limitation shall be applied. 

C. Achievement of the emission standard in subsection A of this section by use of methods in 9VAC5-

40-4790 will be acceptable to the board. 

D. No owner or other person shall use any coating application system or equipment unless reasonable 

precautions are taken to minimize the discharge or emissions from cleaning or purging operations. 

Reasonable precautions may include the following: 

1. The use of capture or control devices or both; 

2. The use of detergents, high pressure water, or other non-volatile cleaning methods; 

3. The minimization of the quantity of volatile organic compounds used to clean lines of equipment; 

and 

4. The adjustment of production schedules to minimize coating changes thereby reducing the need 
for frequent cleaning or purging of a system.
