Section Env-A 1212.07 - VOC Limits for Automotive/Transportation and Business Machine Plastic Part Coating

(a) Except as specified in (b) and (c), below, the owner or operator of an automotive/ transportation or business machine plastic part coating operation subject to this section shall control VOC emissions by using one of the following control options, provided that if a specific coating is subject to more than one emission limit, the least stringent emission limit shall apply:

(1) Control option 1 shall consist of the use of low-VOC content coatings as applied, excluding water and exempt compounds, as specified in table 1212-5, below:

(2) Control option 2 shall consist of the use of one or more add-on controls capable of achieving an overall VOC control efficiency of 90 percent; or

(3) Control option 3 shall consist of using a combination of low-VOC content coatings and one or more add-on controls to meet the limits calculated pursuant to Env-A 1205.01 or specified in table 1212-6, below:

Table 1212-6 VOC Content Limits Per Volume Solids

IV. Fog Coat	0.38	3.14
V. Touchup and Repair	0.57	4.80

(b) For red, yellow, and black automotive/transportation coatings other than touch up and repair coatings, the limit shall be determined by multiplying the appropriate limit in table 1212-5 or 1212-6, as applicable, by 1.15; and

(c) The VOC limits specified in (a), above, shall not apply to the following types of coatings and coating operations:

(1) Texture coatings;

(2) Vacuum-metalizing coatings;

(3) Gloss reducers;

(4) Texture topcoats;

(5) Adhesion primers;

(6) Electrostatic preparation coatings;

(7) Resist coatings; and

(8) Stencil coatings.
