Section Env-A 1212.04 - VOC Limits for Miscellaneous Metal Parts and Products Coating

Except as specified in Env-A 1212.05, the owner or operator of a miscellaneous metal parts and products coating operation subject to this part shall control VOC emissions by 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:

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