NR 205.08 . The term of the permit shall be at least 2 years but no longer than 5 years in duration. (2) Limited coverage of general permits. Under s. 283.35 , Stats., the department may issue a general permit that applies only to certain classes or categories of storm water discharges, or only to storm water discharges located in a designated area of the state, or both. Any limitation of the coverage of a general storm water discharge permit shall be stated in the permit. When the department receives a notice of intent or application for general permit coverage, it shall determine whether the discharge is for a class or category of storm water discharge that is covered by a general permit and is located within an area of the state to which the general permit applies. If the discharge is for a class or category that requires permit coverage but is not covered by a general permit or is for a discharge located outside of the area to which a general permit applies, the department shall treat the notice of intent or application as an application for an individual WPDES permit, and the landowner shall obtain an individual WPDES permit under this chapter for the discharge. (3) Coverage under subsequent permit. Unless notified otherwise by the department, general permittees covered under subchs.
