NR 406.04 Note Note: The application for an operation permit or operation permit revision required under this section will be evaluated by the department pursuant to the permit approval criteria in ss. 285.63 and 285.64, Stats. Application forms may be obtained from the regional and area offices of the department or from the Wisconsin Department of Natural Resources, Bureau of Air Management, PO Box 7921, Madison WI 53707-7921, Attention: operation permits.

NR 406.04(2) (2) General category of exempt sources. In addition to the specific categories of exempt sources identified in sub.
