1. (a) The VOC content or amount of organic solvents and strippable booth coatings associated with a spray booth cleaning operation for a spray booth used in a wood furniture or wood burial casket finishing operation or gunstock coating process shall not, at any time, exceed the following limits:

   1. (1) For organic solvents used to clean spray booth components other than conveyors, continuous coaters and their enclosures, or metal filters of spray booths that are not being refurbished, 8.0% by weight of VOC;
   2. (2) For organic solvents used to clean a spray booth that is being refurbished, 1.0 gallon of organic solvent; and
   3. (3) For strippable booth coatings, 0.8 kg VOC/kg solids, equivalent to 0.8 lb VOC/lb solids, as applied.

2. (b) In addition to the requirements of (a), above, VOC emissions associated with materials storage or solvent cleaning operations applicable to wood furniture or burial casket finishing operations, or gunstock coating, shall be controlled as follows:

   1. (1) All finishing and cleaning materials shall be stored in a normally closed container;
   2. (2) All organic solvent used for line cleaning shall be pumped or drained into a normally closed container;
   3. (3) All organic solvent used to clean spray guns shall be collected into a normally closed container; and

   4. (4) Emissions from washoff operations shall be controlled by:

      1. a. Using normally closed containers for washoff; and
      2. b. Minimizing dripping by tilting or rotating the part to drain as much organic solvent as possible.
