R307-354-6. Work Practice

  (1) Control techniques and work practices are to be implemented at all times to reduce VOC emissions. Control techniques and work practices include:

  (a) Closed containers shall be used for the disposal of solvent wiping cloths;

  (b) Minimizing spills of VOC-containing cleaning materials;

  (c) Conveying VOC-containing materials from one location to another in closed containers or pipes; and

  (d) Cleaning spray guns in enclosed systems or in a non-enclosed paint gun cleaning process may be used if the vapor pressure of the cleaning solvent (excluding water and solvents exempt from the definition of VOCs) is less than 100 mm Hg at 68 degrees Fahrenheit and the solvent is directed towards a drain that leads directly to an enclosed remote reservoir. Automotive spray gun solvent cleaning materials that are defined as a "consumer product" under R307-357 are exempt from the vapor pressure requirement and are regulated under the requirements in R307-357.

  (2) Application equipment requirements:

  (a) A person shall not apply any coating to an automotive part or component unless the coating application method achieves a minimum 65% transfer efficiency. The following coating application methods have been demonstrated to achieve a minimum of 65% transfer efficiency:

  (i) Brush, dip or roll coating operated in accordance with the manufacturers specifications;

  (ii) Electrostatic application equipment operated in accordance with the manufacturers specifications; and

  (iii) High Volume, Low Pressure spray equipment operated in accordance with the manufacturers specifications.

  (3) Other coating application methods may be used that have been demonstrated to be capable of achieving at least 65% transfer efficiency, as certified by the manufacturer.
