When either or both the total suspended solids and BOD of acceptable wastes or wastewater exceed the values ascribed to in Section 923.05(b), the excess concentration of either or both, as the case may be, shall be evaluated volumetrically in terms of "Normal Waste" and be subject to surcharge on the derived volume in accordance with the following formula:
Sv = (Sw-2100)X 0.90 X F X 133,690
2100
Plus(Bw-2100) X 0.90 X F X 133,690
2100
which reduced to its simplest form is
Sv = F [(Sw-2100) 57 Plus (Bw-2100) 57]
Sv = the derived volume of wastes subject
to surcharge expressed in cubic feet
Sw = the pounds per million gallons in the
wastes as discharged denoting "suspended
solids"
Bw = the pounds per million gallons of the
waste as discharged denoting "BOD"
0.90 = factor allowance of 90% degree of
removals
F = the flow expressed in millions of gallons
of the wastes as discharged
133,690 = factor to convert millions of gallons
to an equivalent in cubic feet
