"Surcharge. The city may surcharge industrial users for the treating of abnormal
strength wastes. Water or wastes having:
a. A five-day biochemical oxygen demand greater than 250 parts per million
(ppm) by weight or
b. Containing more than 250 parts per million by weight of total suspended
solids shall be subject to the review and approval of the designated city
official.
Where the designated city official has approved the admission of subsections a.
or b. above into the POTW, that discharge may be subject to a surcharge as
determined by the designated city official. In no case shall a discharge be
accepted that will prevent the POTW from meeting its limits.
The surcharge will be assessed according to the following formula each month
using the most current pollutant concentration data and the current months'
wastewater flow:
Surcharge = Q/1,000,000 x [a(BOD-250) + b(TSS-250)][8.34]
Where:
TABLE INSET:
Q = Flow in gallons
8.34 = Weight in pounds of one gallon of water
x = Normal limits of BOD in domestic wastewater expressed in milligrams per liter
y = Normal limits of TSS in domestic wastewater expressed in milligrams per liter
a = latest unit cost of treatment per pound of BOD.
b = latest unit cost of treatment per pound of TSS.
BOD = Measured amount of BOD, in mg/I
TSS = Measured amount of TSS, in mg/I
A surcharge is an additional charge by the POTW for the increased cost of
handling discharge of unusual strength and character and shall not serve as a
variance to the requirements of this division. Exercise of this provision shall not
be a bar to, or a prerequisite for, taking any other action against the user."

word in this ordinance, or application thereto, any person or circumstances is held
