based on the treatment costs attributable to the removal of BOD.
b = SS surcharge factor (dollars per million gallons per parts per million by weight)
based on the treatment costs attributable to the removal of SS.

Page 6
I A. Any person discharging or proposing to discharge to the public sewers industrial
wastes, which contain the substances or possess the characteristics enumerated

together with such necessary meters and other appurtenances in the building sewer to
facilitate observation, sampling and measurement of the wastes. Such manhole, when
required, shall be accessibly and safely located and shall be constructed in accordance
with plans approved by the Director of Public Works. The manhole shall be installed by
the owner at his expense and shall be maintained by him so as to be safe and accessible
at all times.
B. All measurements, tests and analyses of the characteristics of waters and wastes to

Q: , 13
Ordinance No. 787
Page 7
manhole provided, or upon suitable samples taken at said control manhole. In the
event that no special manhole has been required, the control manhole shall be con-
sidered to be the nearest downstream manhole in the public sewer to the point at
which the building sewer is connected. Sampling shall be carried out by customarily
accepted methods to reflect the effect of constituents upon the sewage works and to
determine the existence of hazards to life, limb and property. The particular analyses
involved will determine whether a 24 hour composite of outfalls of a premise is appropriate
or whether a grab sample or samples should be taken.
C. The Director of Public Works and other duly authorized employees of the City shall
