NR 151.001
NR 151.001 Purpose. This chapter establishes runoff pollution performance standards for non-agricultural facilities and transportation facilities and performance standards and prohibitions for agricultural facilities and practices designed to achieve water quality standards as required by s.
281.16 (2) and
(3), Stats. This chapter also specifies a process for the development and dissemination of department technical standards to implement the non-agricultural performance standards as required by s.

Register September 2002 No. 561, eff. 10-1-02.
NR 151.002
NR 151.002 Definitions. In this chapter:
NR 151.002(1)
(1) “Adequate sod, or self-sustaining vegetative cover" means maintenance of sufficient vegetation types and densities such that the physical integrity of the streambank or lakeshore is preserved. Self-sustaining vegetative cover includes grasses, forbs, sedges and duff layers of fallen leaves and woody debris.
NR 151.002(3)
(3) “Average annual rainfall" means a typical calendar year of precipitation as determined by the department for users of models such as SLAMM, P8, or equivalent methodology. The average annual rainfall is chosen from a department publication for the location closest to the municipality.
NR 151.002 Note
Note: Information on how to access SLAMM and P8 and the average annual rainfall files for five locations in the state, as published periodically by the department, is available at dnr.wi.gov.
NR 151.002(4)
(4) “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.
NR 151.002(5)
(5) “Combined sewer system" means a system for conveying both sanitary sewage and stormwater runoff.
