jurisdiction over discharge to the receiving waters.
E.
Acceptance Of Restricted Discharges. If any waters or wastes are discharged or are proposed to be discharged to the public sewers, which waters contain the substances or possess the characteristics enumerated in Subsection (D) of this Section, and which in the judgment of the Director of Public Works may have a deleterious effect upon the sewage works, processes, equipment or receiving waters, or which otherwise create a hazard to life or constitute a public nuisance, the Director of Public Works may:
1.
Reject the wastes;
2.
Require pretreatment to an acceptable condition for discharge to
the public sewers;
3.
Require control over the quantities and rates of discharge; and
4.
Require payment to cover the added cost of handling and treating the wastes not covered by existing taxes or sewer charges, under the provisions of Subsection (J) of this Section.
|
|
If the Director of Public Works permits the pretreatment or
equalization of waste flows, the design and installation of the plants

H.
Control Manhole. When required by the Director of Public
Works, the owner of any property serviced by a building sewer carrying
industrial wastes shall install a suitable control manhole, 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/her expense, and shall be maintained by him/her so as to be
safe and accessible at all times.
I.
Measurements, Tests And Analyses Of Discharges. All measurements,
tests and analyses of the characteristics of waters and wastes to
which reference is made in this Article shall be determined in accordance
with the latest edition of Standard Methods for the Examination of
Water and Wastewater, published by the American Public Health Association,
and shall be determined at the control manhole provided, or upon suitable
samples taken at the control manhole. If no special manhole has been
required, the control manhole shall be considered 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 twenty-four
(24) hour composite of all outfalls of a premises is appropriate or
whether a grab sample should be taken. Normally, but not always, BOD
and suspended solids analyses are obtained from twenty-four (24) hour
composites of all outfalls, whereas pHs are determined from periodic
grab samples.
J.
Special Agreements With Industrial Users. No statement contained
in this Section shall be construed as preventing any special agreement
or arrangement between the City and any industrial concern, whereby
an industrial waste of unusual strength or character may be accepted
by the City for treatment, subject to payment therefor by the industrial
concern.
