For the details of the requirements, refer to the text of the regulation.
bRefer to Part B to determine which paragraphs of subs. (5), (6) and (8) correspond to each compliance provision (sub. (4)).
cAs per sub. (1) (b), any new coating operation with solvent utilization <38 m3/yr or any modified or reconstructed coating operation with solvent utilization <370 m3/yr is exempt from the VOC standards (sub.
