(a) Discharges composed entirely of storm water are not storm water discharges associated with industrial activity if there is no exposure of industrial materials and activities to storm water, and the discharger satisfies the conditions in pars.
(b) to
(e). “No exposure" means that all industrial materials and activities are protected by a storm resistant shelter to prevent exposure to storm water. Industrial materials or activities include material handling equipment or activities, industrial machinery, raw materials, intermediate products, by-products, final products or waste products. Material handling activities include the storage, loading and unloading, transportation or conveyance of any raw material, intermediate product, final product or waste product.
NR 216.21(3)(b)
(b)
Qualification. To qualify for this exclusion, the operator of the discharge shall do all of the following:

NR 216.22 (7), a certification that there are no discharges of storm water contaminated by exposure to industrial materials and activities from the entire facility, except as provided in par.
(c).
NR 216.21(3)(b)3.
3. Submit an initial “no exposure” certification to the department at least 14 working days prior to the start of industrial operations on a form available from the department as specified under s.
