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. (3)). Such coating operations are subject only to subs. (5) (a) and (8) (b) and (c). However, should a coating operation once exceed the applicable annual solvent utilization cutoff, that coating operation shall be subject to the VOC standards (sub. (3)) and all other applicable subsections. Once this has occurred, the coating operation shall remain subject to those requirements regardless of changes in annual solvent utilization.
