(1) 
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:
(a) 
Design guidance and technical standards identified or developed by the Wisconsin Department of Natural Resources under Subchapter V of Chapter NR 151, Wis. Adm. Code.
(b) 
Technical standards and other guidance identified within the Village Stormwater Reference Guide.[1]
[1]
Editor's Note: The Stormwater Reference Guide is included as an attachment to this chapter.
(c) 
For 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.
(2) 
Other Standards. Other technical standards not identified or developed in Sub. (1), may be used provided that the methods have been approved by the Director.
(1) 
Responsible Party. The responsible party shall implement an-erosion and sediment control plan developed in accordance with Section 10.09 that incorporates the requirements of this section.
(2) 
Plan. A written erosion and sediment control plan shall be developed in accordance with Section 10.09 and implemented for each construction site.
(3) 
Requirements. The erosion and sediment control plan required shall meet the following minimum requirements to the maximum extent practicable:
(a) 
BMPs shall be designed, installed and maintained to control total suspended solids carried in runoff from the construction site as follows.
1. 
For construction sites with one acre or greater of land disturbing construction activity, BMPs that, by design, discharge no more than 5 tons per acre per year, or to the maximum extent practicable, of the sediment load carried in runoff from initial grading to final stabilization. No person shall be required to exceed sediment reduction to meet the requirements of this paragraph. Erosion and sediment control BMPs may be used alone or in combination to meet the requirements of this paragraph. Credit toward meeting the sediment reduction shall be given for limiting the duration or area, or both, of land disturbing construction activity, or other appropriate mechanism.
2. 
For construction sites with less than one acre of land disturbing construction activity, reduce the total suspended solids load using BMPs from the Village Stormwater Reference Guide. These sites are not required to satisfy a numeric performance standard.
(b) 
Notwithstanding Par. (a), if BMPs cannot be designed and implemented to reduce the sediment load, on an average annual basis, the plan shall include a written and site-specific explanation as to why the reduction goal is not attainable and the sediment load shall be reduced to the maximum extent practicable.
(c) 
Where appropriate, the plan shall include sediment controls to do all of the following to the maximum extent practicable:
1. 
The deposition of soil from being tracked onto streets by vehicles.
2. 
The discharge of sediment from disturbed areas into on-site storm water inlets.
3. 
The discharge of sediment from disturbed areas into adjacent waters of the state.
4. 
The discharge of sediment from drainage ways that flow off the site.
5. 
The discharge of sediment by dewatering activities.
6. 
The discharge of sediment eroding from soil stockpiles existing for more than 7 days.
7. 
The discharge of sediment from erosive flows at outlets and in downstream channels.
8. 
The transport by runoff into waters of the state of chemicals, cement, and other building compounds and materials on the construction site 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 subdivision.
9.
