R307-353-5. VOC Content Limits

  (1) For automobile and truck plastic parts coating lines:

  (a) No owner or operator shall apply coatings with a VOC content greater than the amounts specified in Table 1, unless the owner or operator uses an add-on control device as specified in R307-353-8.

  (b) For red and black coatings, the content limitation shall be determined by multiplying the appropriate limit in Table 1 by 1.15.

  (c) When EPA Method 24 is used to determine the VOC content of a high bake coating, the applicable content limitation shall be determined by adding 0.5 to the appropriate limit in Table 1.

  (d) When EPA Method 24 is used to determine the VOC content of an air-dried coating, the applicable content limitation shall be determined by adding 0.1 to the appropriate limit in Table 1.
