9VAC5-40-8830. 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 the limits contained in Tables 4-59A through 4-59E. The VOC content limits are mass VOC per gallon of coating less water and exempt solvents and are based on low-VOC coatings. If more than one emission limitation in this subsection applies to a specific coating, then the least-stringent emission limitation shall be applied.

C. Should product performance requirements or other needs dictate the use of higher-VOC materials than those that would meet the emission limits of subsections A and B of this section, an affected facility may opt to use add-on control equipment with an overall control efficiency of 90% in lieu of using low-VOC coatings and required application methods in subsection E of this section. Add-on devices include but are not limited to oxidizers, adsorbers, absorbers, and concentrators. Add-on devices coupled with capture systems to collect the VOC being released at the affected facilities shall achieve an overall control efficiency of no less than 90%.

D. In addition to the emissions limitations described in subsections A, B, and C of this section, the following work practices for storage, mixing operations, and handling operations for coatings, thinners, and coating-related waste materials shall be utilized:

1. All VOC-containing coatings, thinners, and coating-related waste materials shall be stored in closed containers.

2. Mixing and storage containers used for VOC-containing coatings, thinners, and coating-related waste materials shall be kept closed at all times except when depositing or removing these materials.

3. Spills of VOC-containing coatings, thinners, and coating-related waste materials shall be minimized.

4. VOC-containing coatings, thinners, and coating-related waste materials shall be conveyed from one location to another in closed containers or pipes.

E. In addition to the work practices described in subsection D of this section, the following work practices for cleaning materials, used to clean surfaces before coating (surface preparation) and to clean application equipment between coating jobs, shall be utilized:

1. All VOC-containing cleaning materials and used shop towels shall be stored in closed containers.

2. Storage containers used for VOC-containing cleaning materials shall be kept closed at all times except when depositing or removing these materials.

3. Spills of VOC-containing cleaning materials shall be minimized.

4. VOC-containing cleaning materials shall be conveyed from one location to another in closed containers or pipes.

5. VOC emissions from cleaning of application, storage, mixing, and conveying equipment shall be minimized by ensuring that equipment cleaning is performed without atomizing the cleaning solvent and all spent solvent is captured in closed containers.

F. One or more of the following application techniques shall be used to apply any finish material listed in Tables 4-59A through 4-59I:

1. Flow/curtain coating;

2. Dip coating;

3. Roller coating;

4. Brush coating;

5. Electrodeposition coating;

6. High volume low pressure (HVLP) spraying;

7. Electrostatic spray;

8. Airless spray;

9. Air-assisted airless spray; or

10. Other coating application methods that achieve emission reductions equivalent to or greater than those achieved by HVLP or electrostatic spray application methods.
