A. 
Design criteria, standards and specifications. All BMPs required to comply with this chapter shall meet the design criteria, standards and specifications based on any of the following:
(1) 
Design guidance and technical standards identified or developed by the Wisconsin Department of Natural Resources under Subchapter V of Ch. NR 151, Wis. Adm. Code.
(2) 
Technical standards and other guidance identified within the Town of Grand Chute Erosion and Sediment Control Reference Guide.
(3) 
Soil loss prediction tools, such as the Revised Universal Soil Loss Equation 2 (RUSLE2), that estimate the sediment load leaving the site under varying land and management conditions may be used to show compliance with the sediment performance standards pursuant to § 275-7B of this chapter.
(4) 
In this chapter, average annual basis is calculated using the appropriate annual rainfall or runoff factor, also referred to as the "R factor," or an equivalent design storm using a Type II distribution, with consideration given to the geographic location of the site and the period of disturbance.
B. 
Other standards. Other technical standards not identified in this chapter may be used, provided that the methods have been approved by the administering authority.
A. 
Nonpermitted sites.
(1) 
Responsible party. The landowner of the construction site, or other person contracted or obligated by other agreement with the landowner to implement and maintain construction site BMPs, is a responsible party and shall comply with the requirements of this chapter.
(2) 
Requirements. At each site where land disturbing construction activity is to occur, BMPs shall be used 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 stormwater inlets.
(c) 
The discharge of sediment from disturbed areas into adjacent waters of the state.
(d) 
The discharge of sediment from drainageways 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 seven days.
(g) 
The discharge of on-site chemicals, cement and other building compounds and materials into waters of the state or off-site separate storm sewers during the construction period. However, projects that require the placement of these materials in waters of the state, such as constructing bridge footings or BMP installations, are not prohibited by this chapter.
(3) 
Location. BMPs shall be located so that treatment occurs before runoff enters waters of the state and off-site separate storm sewers. However, projects that require BMP placement in waters of the state, such as a turbidity barrier, are not prohibited by this chapter.
(4) 
Implementation. The BMPs used to comply with the requirements of this chapter shall be implemented as follows:
(a) 
Erosion and sediment control practices shall be constructed or installed before land disturbing construction activities begin.
(b) 
Erosion and sediment control practices shall be maintained until final stabilization.
(c) 
Final stabilization activity shall commence when land disturbing construction activities cease and final grade has been reached on any portion of the site.
(d) 
Temporary stabilization activity shall commence when land disturbing construction activities have temporarily ceased and will not resume for a period exceeding 14 calendar days.
(e) 
BMPs that are no longer necessary for erosion and sediment control shall be removed by the responsible party.
(5) 
Alternate requirements. The administering authority may establish erosion and sediment control requirements more stringent than those set forth in this chapter if the administering authority determines that an added level of protection is needed to protect resources.
B. 
Permitted sites.
(1) 
Responsible party. The landowner or other person performing services to meet the performance standards of this chapter, through a contract or other agreement with the landowner, is a responsible party and shall comply with the requirements of this chapter.
(2) 
Plan. A written erosion and sediment control plan shall be developed and implemented by the responsible party in accordance with § 275-9 of this chapter and shall meet all other applicable requirements contained herein.
(3) 
Requirements. The erosion and sediment control plan shall meet all of the following:
(a) 
The plan shall use BMPs to prevent or reduce all of the following:
[1] 
The deposition of soil from being tracked onto streets by vehicles.
[2] 
The discharge of sediment from disturbed areas into stormwater inlets.
[3] 
The discharge of sediment from disturbed areas into adjacent waters of the state.
[4] 
The discharge of sediment from drainageways that flow off the site.

[9] 
The discharge of untreated wash water from vehicle and wheel washing into waters of the state or off-site separate storm sewers.
(b) 
For sites with one acre or more of land disturbing construction activity, the plan shall meet the following sediment performance standards:
[1] 
BMPs that, by design, discharge no more than five tons per acre per year, or to the maximum extent practicable, of the sediment load carried in runoff from initial grading to final stabilization.
[2] 
Except as provided in § 275-7B(6), the administering authority may not require any person to employ more BMPs than are needed to meet the five-tons-per-acre-per-year sediment performance standard in order to comply with the maximum extent practicable. Erosion and sediment control BMPs may be combined to meet the sediment performance standard. The administering authority may give credit toward meeting the sediment performance standard for limiting the duration and/or area of land disturbing construction activity or for other appropriate mechanisms.
[3] 
Notwithstanding the provisions in § 275-7B(3)(b)[1] and [2], if BMPs cannot be designed and implemented to meet the five-tons-per-acre-per-year sediment performance standard, the plan shall include a written, site-specific explanation of why the sediment performance standard cannot be met and how the sediment load will be reduced to the maximum extent practicable.
(c) 
The plan shall incorporate all of the following preventative measures:
[1] 
Maintenance of existing vegetation, especially adjacent to surface waters, whenever possible.
[2] 
Minimization of soil compaction and preservation of topsoil.
[3] 
Minimization of land disturbing construction activity on slopes of 20% or more.
[4] 
Development of spill prevention and response procedures.
(4) 
Location. BMPs shall be located so that treatment occurs before runoff enters waters of the state and off-site separate storm sewers. However, projects that require BMP placement in waters of the state, such as a turbidity barrier, are not prohibited by this chapter.
(5) 
Implementation. The BMPs used to comply with the requirements of this chapter shall be implemented as follows:
(a) 
In accordance with the plan developed pursuant to § 275-9, the erosion and sediment control practices shall be constructed or installed before land disturbing construction activities begin.
(b) 
Erosion and sediment control practices shall be maintained until final stabilization.
(c) 
Final stabilization activity shall commence when land disturbing construction activities cease and final grade has been reached on any portion of the site.
(d) 
Temporary stabilization activity shall commence when land disturbing construction activities have temporarily ceased and will not resume for a period exceeding 14 calendar days.
(e) 
BMPs that are no longer necessary for erosion and sediment control shall be removed by the responsible party.
(6) 
Targeted performance standards. The administering authority may establish numeric water quality requirements that are more stringent than those set forth in § 275-7B(3) in order to meet targeted performance standards, total maximum daily loads, and/or water quality standards for a specific water body or area. The numeric water quality requirements may be applicable to any permitted site, regardless of the size of land disturbing construction activity.
(7) 
Alternate requirements. The administering authority may establish erosion and sediment control requirements more stringent than those set forth in this chapter if the administering authority determines that an added level of protection is needed to protect resources. Additionally, the administering authority may establish erosion and sediment control requirements less stringent than those set forth in this chapter if the administering authority determines that less protection is needed to protect resources. However, the alternative requirements shall not be less stringent than those requirements promulgated in rules by Wisconsin Department of Natural Resources under Ch. NR 151, Wis. Adm. Code. The established additional requirements shall be provided to the applicant in writing.
A. 
Permit required. When a permit is required, no responsible party may undertake a land disturbing construction activity without prior approval of an erosion and sediment control plan for the site and receipt of a permit from the administering authority.
B. 
Permit application and fees. When a permit is required, any responsible party desiring to undertake a land disturbing construction activity shall submit to the approving authority a permit application made on a form provided by the administering authority for that purpose.
