SPS 360.20SPS 360.20 Erosion and sediment control. SPS 360.20(1)(a)(a) Where land disturbing construction activity is to occur erosion and sediment control practices shall be employed, as necessary, and maintained to prevent or reduce the potential deposition of soil or sediment to all of the following: SPS 360.20(1)(b)(b) Land disturbing construction activities, except those activities necessary to implement erosion or sediment control practices, may not begin until the sediment control practices are in place for each area to be disturbed in accordance with the erosion and sediment control plan. SPS 360.20(1)(c)(c) Erosion and sediment control practices shall be maintained until the disturbed areas are stabilized. A disturbed area shall be considered stabilized when a perennial cover has been established with a density of at least 70%. SPS 360.20(1)(d)(d) Erosion and sediment control practices shall either be approved by the department or listed by the department of natural resources in accordance with the process under s. NR 151.32 (2). SPS 360.20 NoteNote: Listed practices can be found through the Department’s Division of Industry Services website at http://dsps.wi.gov/programs/industry-services or by contacting the Division at telephone (608) 266-3151 or 877/617-1565 or 411 (Telecommunications Relay). SPS 360.20(2)(2) Mandated practices. Specific practices at each site where land disturbing construction activity is to occur shall be utilized to prevent or reduce all of the following: SPS 360.20(2)(a)(a) The deposition of soil from being tracked onto streets by vehicles.
