NR 216.001 Purpose. The purpose of this chapter is to establish criteria defining those storm water discharges needing WPDES storm water permits, as required by s.
283.33, Stats., and to implement the appropriate performance standards of subchs.

Additional definitions may be found in s.
NR 205.03.
NR 216.002(1m)
(1m) “Benchmark" means a minimum numeric or narrative level of pollution control required to demonstrate progress toward a required level of pollution control.
NR 216.002(1r)
(1r) “Best management practices" or “BMPs" means structural or non-structural measures, practices, techniques or devices employed to avoid or minimize soil, sediment or pollutants carried in runoff to waters of the state.

(2) “Construction site" means an area upon which one or more land disturbing construction activities occur that in total will disturb one acre or more of land, including areas that are part of a larger common plan of development or sale where multiple separate and distinct land disturbing construction activities may be taking place at different times on different schedules but under one plan such that the total disturbed area is one acre or more. A long-range planning document that describes separate construction projects, such as a 20-year transportation improvement plan, is not a common plan of development.
NR 216.002(3)
(3) “Contaminated storm water" means storm water that comes into contact with material handling equipment or activities, raw materials, intermediate products, final products, waste materials, byproducts or industrial machinery in the source areas listed in s.

NR 216.002(4)
(4) “Department" means the department of natural resources.
NR 216.002(6)

(7) “Erosion" means the process by which the land's surface is worn away by the action of wind, water, ice or gravity.
NR 216.002(8)
(8) “Final stabilization" means that all land disturbing construction activities at the construction site have been completed and that a uniform perennial vegetative cover has been established with a density of at least 70% of the cover for the unpaved areas and areas not covered by permanent structures or that employ equivalent permanent stabilization measures.
NR 216.002(9)
(9) “General WPDES permit" or “general permit" means a permit for the discharge of pollutants issued by the department under s.

NR 216.002(14)
(14) “Land disturbing construction activity" means any man-made alteration of the land surface resulting in a change in the topography or existing vegetative or non-vegetative soil cover that may result in storm water runoff and lead to increased soil erosion and movement of sediment into waters of the state.
