(2)Penalties. Penalties for violations of this chapter shall be assessed in accordance with s. 101.02 (13), Stats.
Note: Section 101.02 (13), Stats., provides for fines of up to $100 for each violation of rules promulgated under this section. Each day of continued violation may constitute a separate offense.
Note: For a site where one or more acres of land disturbing construction activity occurs, the Department of Natural Resources has the ability to inspect and pursue enforcement action under the issuance of the Wisconsin Pollutant Discharge Elimination System, WPDES, General Permit pursuant to chapter NR 216.

Subchapter III — Erosion and Sediment Control
SPS 360.20Erosion and sediment control.
(1)General.
(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:
1. The waters of the state.
2. Adjacent properties.
(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.
(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%.
(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).
Note: 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).
(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:
(a) The deposition of soil from being tracked onto streets by vehicles.
(b) The discharge of sediment from disturbed areas into on-site storm water inlets.
(c) The discharge of sediment from disturbed areas into abutting waters of the state.
(d) The discharge of sediment from drainage ways that flow off the site.
(e) The discharge of sediment by dewatering activities.
(f) The discharge of sediment eroding from soil stockpiles existing for more than 7 days.
(3)Control standards. Including the practices under sub. (2), additional erosion and sediment control practices shall be employed, as necessary, to accomplish one of the following:
(a) A potential annual cumulative soil loss rate of not more than one of the following:
1. Five tons per acre per year where sand, loamy sand, sandy loam, loam, sandy clay loam, clay loam, sandy clay, silty clay or clay textures are exposed.
2. Seven and a half tons per acre per [year] where silt, silty clay loam or silt loam textures are exposed.
Note: A missing word is shown in brackets.
(b) A reduction of at least 80% of the potential sediment load in storm water runoff from the site on an average annual basis as compared with no sediment or erosion controls for the site when the land disturbing construction activity involves one or more acres.
(c) A reduction of at least 40% of the potential sediment load in storm water runoff from the site on an average annual basis as compared with no sediment or erosion controls for the site where less than one acre of land disturbing construction activity is to occur.
Note: See appendix for further explanatory material regarding compliance solutions for 80 and 40% reductions.
(4)Soil loss analysis. Potential soil loss shall be determined using an engineer analytical modeling acceptable to the department.
Note: The Revised Universal Soil Loss Equation II is an example of an acceptable method to determine soil loss.
History: CR 05-113: cr. Register December 2006 No. 612, eff. 4-1-07.
SPS 360.21Monitoring. The owner or owner’s agent shall check the erosion and sediment control practices for maintenance needs at all the following intervals until the site is stabilized:
(1)At least weekly.
(2)Within 24 hours after a rainfall event of 0.5 inches or greater. A rainfall event shall be considered to be the total amount of rainfall recorded in any continuous 24 hour period.
(3)At all intervals that are cited on the erosion and sediment control plan.

SPS 360.22Maintenance.
(a) Except as provided in par. (c), off-site sediment deposition resulting from the failure of an erosion or sediment control practice shall be cleaned up by the end of the next day.
Note: Contact the Department of Natural Resources before attempting to clean up any sediment deposited or discharged into the waters of the state.
(b) Except as provided in par. (c), off-site soil deposition, resulting from construction activity, that creates a nuisance shall be cleaned up by the end of the work day.
(c) A municipality may enact more stringent requirements regarding cleanup of soil or sediment deposition onto public ways.
(a) Except as required in par. (b), the owner or owner’s agent shall complete repair or replacement of erosion and sediment control practices or devices as necessary within 48 hours of an interval specified under s. SPS 360.21.
(b) When the failure of erosion or sediment control practices results in an immediate threat of sediment entering public sewers or the waters of the state, procedures shall be implemented immediately to repair or replace the practices.
