A-382.36 (3) SOURCES OF POLLUTANTS IN WISCONSIN STORMWATER.
SOURCES OF POLLUTANTS IN WISCONSIN STORMWATER
Geometric Mean Concentrations of Contaminants in Runoff from Source-Area and Storm-Sewer Outfalls
Source:   Bannerman, R.T.; Owens D.W.; Dodds, R.B.; and Hornewer, N.J., 1993, Sources of Pollutants in Wisconsin Stormwater: Water Science Technology, v.28, nos. 3-5, pp. 241-259.
Note: Single dash indicates source area is not in the land use; double dash indicates insufficient data; and triple dash indicates values are shared with those above for the same source area. The relatively large concentrations of zinc in roof runoff indicate that galvanized roofing materials were a source of the zinc. One-third of the residential roofs had galvanized downspouts. Roofing materials also might be a source of copper and lead in the runoff from residential roofs. Concentrations of dissolved copper and total recoverable copper and lead were slightly larger in the residential roof runoff than in runoff from driveways and lawns.
Note: The department has accepted that a “visible sheen” is defined as 15 mg/L grease and oil.
A-382.36 (3)-1. BEST MANAGEMENT PRACTICES (BMPs). A description of the proposed best management practices to be used for stormwater management in the protection of water quality include, but are not limited to, the following:
a.   Detention, retention and sedimentation facilities, including plans for discharges from the facilities, maintenance plans and predictions of water quality.
b.   Areas of the site to be used or reserved for infiltration including a prediction of the impact on groundwater quality.
c.   Any other relevant volume controls or measures.
d.   Any other relevant source control practices not described.
e.   Any treatment device, including plans for discharges from the facilities, maintenance plans and predictions of water quality.
Note: Section NR 151.002 (4) reads: “‘Best management practices’ or ‘BMPs’ means structural or non-structural measures, practices, techniques or devices employed to avoid or minimize soil, sediment or pollutants carried in runoff to waters of the state.”
A-382.36 (4)-1. RATIONAL METHOD. The equation procedure for using the rational method formula is as follows:
  Q   =   Aci (in cubic feet per second)
Where:   Q   =   Runoff (in cubic feet per second)
  A   =   Drainage area (in acres)
  c   =   Coefficient of runoff (a dimensionless number)
  i   =   Intensity of rainfall (in inches per hour)
  Q   =   (0.0104)ciA (in gallons per minute)
      (1/96)ciA
Where:   Q   =   Runoff (in gallons per minute)
  c   =   Coefficient of runoff (a dimensionless number)
  i   =   Intensity of rainfall (in inches per hour)
  A   =   Drainage area (in square feet)
A-382.36 (4)-2. RUNOFF COEFFICIENTS. Tables Detail A and B are for using the rational formula.
