Section 8530. Standard for volatile organic compounds

A. No owner or other person shall cause or permit to be discharged into the atmosphere any VOC emissions from any solvent cleaning operation employing industrial cleaning solvents in excess of both of the following limits:

1. A VOC content limit of 50 grams per liter (0.42 pounds per gallon) of industrial cleaning solvent shall apply unless emissions are controlled by an emission control system with an overall control efficiency of at least 85%; and

2. A composite vapor pressure limit of eight millimeters of mercury at 20°C.

B. VOC emissions from the use, handling, storage, and disposal of industrial cleaning solvents and shop towels shall be controlled by the following work practices:

1. Open containers and used applicators shall be covered.

2. Air circulation around cleaning operations shall be minimized.

3. Used solvent and shop towels shall be disposed of properly.

4. Equipment practices that minimize emissions (including but not limited to keeping arts cleaners covered and maintaining cleaning equipment to repair solvent leaks) shall be implemented.

C. In lieu of complying with the requirements of subsections A and B of this section, a manufacturer of coatings, inks, resin, or adhesives may comply with the following requirements:

1. Clean portable or stationary mixing vats, high dispersion mills, grinding mills, tote tanks, and roller mills by one or more of the following methods:

a. Use a cleaning solvent that either contains less than 1.67 pounds per gallon of VOC or has a composite vapor pressure no more than eight mmHg at 20°C.

b. Comply with the following work practices:

(1) Equipment being cleaned shall be maintained leak free;

(2) VOC-containing cleaning materials shall be drained from the cleaned equipment upon completion of cleaning;

(3) VOC-containing cleaning materials, including waste solvent, shall not be stored or disposed of in such a manner that will cause or allow evaporation into the atmosphere; and

(4) All VOC-containing cleaning materials shall be stored in closed containers.

c. Collect and vent the emissions from equipment cleaning to a VOC emission control system that has an overall capture and control efficiency of at least 80%, by weight, for the VOC emissions. Where such reduction is achieved by incineration, at least 90% of the organic carbon shall be oxidized to carbon dioxide.

d. Use organic solvents other than those allowed in subdivision 1 a of this subsection provided no more than 60 gallons of fresh solvent shall be used per month. Organic solvent that is reused or recycled (either on site or off site) for further use in equipment cleaning or the manufacture of coating, ink, or adhesive shall not be included in this limit. All VOC-containing cleaning materials shall be stored in closed containers.

2. When using solvent for wipe cleaning, the owner shall not (i) use open containers for the storage or disposal of cloth or paper impregnated with organic compounds that is used for cleanup, or coating, ink, or adhesive removal and (ii) store spent or fresh organic compounds to be used for cleanup or coating, ink, resin, or adhesive removal in open containers.

3. Any manufacturer of coatings, inks, resin, or adhesives that complies with subdivision 1 d of this subsection shall record the following information each month for each cleaning material and shall maintain the information at the facility for a period of five years: (i) the total volume of fresh cleaning solvent material used for equipment cleaning and (ii) the total volume of cleaning solvent material recovered for either on-site or off-site recycling.

D. The control requirements for screen printing shall be either use of solvent technology at 4.2 pounds of VOC per gallon, or the use of a product with a vapor pressure of eight mm Hg.
