An erosion control plan shall describe how the permit holder and other responsible party will minimize, to the maximum extent practicable, soil erosion and the transport of sediment from land disturbing activities. To meet this requirement, the following performance standards shall apply:
A. 
All erosion control plans and associated BMPs shall comply with the planning, design, implementation and maintenance requirements of this chapter.
B. 
All erosion control plans shall, by design, achieve to the maximum extent practicable a reduction of 80% of the sediment load carried in runoff, on an average annual basis, as compared with no sediment or erosion controls, until the site is stabilized.
C. 
Erosion and sediment control BMPs may be used alone or in combination to meet the 80% sediment reduction goal. Plans that comply with the guiding principles described in § 367-19 below and the specific erosion control plan requirements described in § 367-20 below shall be determined by the Designated City Representative as meeting the 80% sediment reduction goal.
D. 
The Designated City Representative may recognize other methods for determining compliance with the 80% sediment reduction goals as they are standardized, including any methods that may come from the procedures under Subchapter V of Ch. NR 151, Wis. Adm. Code.
Note: Soil loss prediction tools are available that can estimate the sediment load leaving the construction site under varying land and management conditions and the application of erosion control BMPs. An example of such a tool is the Revised Universal Soil Loss Equation, published by the USDA Natural Resources Conservation Service.
To satisfy the requirements of this article, an erosion control plan shall, to the maximum extent practicable, adhere to the following guiding principles:
A. 
Propose grading that best fits the terrain of the site, avoiding steep slopes, wetlands, floodplains and environmental corridors.
B. 
Minimize, through project phasing and construction sequencing, the time the disturbed soil surface is exposed to erosive forces.
C. 
Minimize soil compaction, the loss of trees and other natural vegetation and the size of the disturbed area at any one time.
D. 
Locate erosion control BMPs prior to runoff leaving the site or entering waters of the state and outside of wetlands, floodplains, primary or secondary environmental corridors or isolated natural areas.
E. 
Emphasize the use of BMPs that prevent soil detachment and transport over those aimed to reduce soil deposition (sedimentation) or repair erosion damage.
The following applicable minimum requirements shall be addressed in erosion control plans to the maximum extent practicable. The Designated City Representative may establish more stringent erosion and sediment control requirements than the minimums set forth in this section if the Designated City Representative determines that an added level of protection is needed to protect an environmentally sensitive area or other property, or to address a change made during plan implementation.
A. 
Access drives and tracking. Provide access drives for construction vehicles that minimize tracking of soil off-site using BMPs such as stone tracking pads, tire washing or grates. Minimize runoff and sediment from adjacent areas from flowing down or eroding the access drive.
B. 
Diversion of upslope runoff. Divert excess runoff from upslope land, rooftops or other surfaces, if practicable, using BMPs such as earthen diversion berms, silt fence and downspout extenders. Prevent erosion of the flow path and the outlet.
C. 
Inlet protection. Protect inlets to storm drains, culverts and other stormwater conveyance systems from siltation until the site is stabilized.
D. 
Soil stockpiles. Locate soil stockpiles away from channelized flow and no closer than 25 feet from roads, ditches, lakes, streams, ponds, wetlands or environmental corridors, unless otherwise approved by the Designated City Representative. Control sediment from soil stockpiles. Any soil stockpile that remains for more than 30 days shall be stabilized.
E. 
Cut-and-fill slopes. Minimize the length and steepness of proposed cut-and-fill slopes and stabilize them as soon as practicable.
F. 
Channel flow. Trap sediment in channelized flow before discharge from the site using BMPs such as sediment traps and sediment basins. Stabilize open channels in accordance with Designated City Representative standards as soon as practicable.
G. 
Outlet protection. Protect outlets from erosion during site dewatering and stormwater conveyance, including velocity dissipation at pipe outfalls or open channels entering or leaving a stormwater management facility.
H. 
Overland flow. Trap sediment in overland flow before discharge from the site using BMPs such as silt fence and vegetative filter strips.
I. 
Site dewatering. Treat pumped water to remove sediment prior to discharge from the site, using BMPs such as sediment basins and portable sediment tanks.
J. 
Dust control. Prevent excessive dust from leaving the construction site though construction phasing and timely stabilization or the use of BMPs such as site watering and mulch, especially with very dry or fine sandy soils.
K. 
Topsoil application. Save existing topsoil and reapply a minimum of four inches to all disturbed areas for final stabilization, unless otherwise approved by the Designated City Representative, such as for temporary seeding or stormwater infiltration BMPs. If adequate topsoil does not exist on the site to meet this requirement, it shall be imported.
L. 
Waste material. Recycle or properly dispose all waste and unused building materials in a timely manner. Control runoff from waste materials until they are removed or reused.
M. 
Sediment cleanup. By the end of each workday, clean up all off-site sediment deposits or tracked soil that originated from the permitted site. Flushing shall not be allowed unless runoff is treated before discharge from the site.
N. 
Final site stabilization. All previous cropland areas where land disturbing activities will not be occurring under the proposed grading plans shall be stabilized upon permit issuance. Stabilize all other disturbed areas within seven days of final grading and topsoil application. Large sites shall be treated in stages as final grading is completed in each stage. Any soil erosion that occurs after final grading or the application of stabilization measures must be repaired and the stabilization work redone.
O. 
Temporary site stabilization. Any disturbed site that remains inactive for greater than seven days shall be stabilized with temporary stabilization measures such as soil treatment, temporary seeding or mulching. For purposes of this subsection, "inactive" means that no site grading, landscaping or utility work is occurring on the site and that precipitation events are not limiting these activities. Frozen soils do not exclude the site from this requirement.
P. 
Removal of practices. Remove all temporary BMPs such as silt fences, ditch checks and sediment traps as soon as all disturbed areas have been stabilized.
Q. 
Site drainage. Site drainage plans shall comply with the provisions of § 367-26F below.
Preliminary erosion and sediment control plans shall contain the following items:
A. 
A site map in accordance with § 367-25 below;
B.
