9. The transport by runoff into waters of the state of untreated wash water from vehicle and wheel washing.
NR 151.23 Note
Note: Wastewaters, such as from concrete truck washout, need to be properly managed to limit the discharge of pollutants to waters of the state. A separate permit may be needed from the department where a wastewater discharge has the potential to adversely impact waters of the state. The appropriate department regional wastewater specialist should be contacted to determine if wastewater permit coverage is needed where wastewater will be discharged to waters of the state.
NR 151.23(4m)(b)
(b) Sediment performance standards. In addition to the erosion and sediment control practices under par.

1. For transportation facility construction sites for which the department received a notice of intent for the construction project in accordance with subch.
III of ch. NR 216 within 2 years after January 1, 2011, BMPs that, by design, achieve a reduction of 80 percent, or to the maximum extent practicable, of the sediment load carried in runoff, on an average annual basis, as compared with no sediment or erosion controls, until the construction site has undergone final stabilization.
NR 151.23(4m)(b)2.
2. For transportation facility construction sites for which the department received a notice of intent for the construction project in accordance with subch.

3. The department may not require any person to employ more BMPs than are needed to meet a performance standard in order to comply with maximum extent practicable. Erosion and sediment control BMPs may be combined to meet the requirements of this paragraph. The department shall give credit toward meeting the sediment performance standard of this paragraph for limiting the duration or area, or both, of land disturbing construction activity, or for other appropriate mechanisms.
NR 151.23(4m)(b)4.
4. Notwithstanding subd.
1. or
2., if BMPs cannot be designed and implemented to meet the 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.
NR 151.23 Note
Note: The department of natural resources has developed guidance document no. 3800-2017-03 to assist with compliance with the 5 tons per acre sediment performance standard.
