[CC 1984 §24.630]
A.
No
person shall discharge or cause to be discharged the following described
substances, materials, waters or wastes if it appears likely in the
opinion of the Public Works Director that such wastes can harm either
the sewers, sewage treatment process or equipment, have an adverse
effect on the receiving stream or can otherwise endanger life, limb,
public property or constitute a nuisance. In forming his/her opinion
as to the acceptability of these wastes, the Public Works Director
will give consideration to such factors as the quantities of subject
wastes in relation to flows and velocities in the sewers, materials
of construction of the sewers, nature of the sewage treatment process,
capacity of the sewage treatment plant, degree of treatability of
wastes in the sewage treatment plant and other pertinent factors.
The substances prohibited are:
1.
Any liquid or vapor having a temperature higher than one hundred
fifty degrees Fahrenheit (150°F) (sixty-five degrees Celsius (65°C)).
2.
Any water or waste containing fats, wax, grease or oils, whether
emulsified or not, in excess of one hundred (100) mg/l or containing

similar objectionable or toxic substances or wastes exerting an excessive
chlorine requirement to such degree that any such material received
in the composite sewage at the sewage treatment works exceeds the
limits established by the Public Works Director for such materials.
6.
Any waters of wastes containing phenols or other taste- or odor-producing
substances in such concentrations exceeding limits which may be established
by the Public Works Director as necessary, after treatment of the
composite sewage, to meet the requirements of State, Federal or other
public agencies of jurisdiction for such discharge to the receiving
waters.
7.
Any radioactive wastes or isotopes of such half-life or concentration
as may exceed limits established by the Public Works Director in compliance
with applicable State or Federal regulations.
8.
Any waters of wastes having a pH in excess of nine and five tenths
(9.5).
9.
Materials which exert or cause:
a.
Unusual concentrations of inert suspended solids (such as, but not
limited to, Fuller's earth, lime slurries and lime residues) or of
dissolved solids (such as, but not limited to, sodium sulfate).
b.
Excessive discoloration (such as, but not limited to, dye wastes
and vegetable tanning solutions).
c.
Unusual BOD, chemical oxygen demand, or chlorine requirements in
such quantities as to constitute a significant load on the sewage
treatment works.
d.
Unusual volume of flow or concentration of wastes constituting "slugs"
as defined herein.
10.
Waters or wastes containing substances which are not amenable to
treatment or reduction by the sewage treatment processes employed
or are amenable to treatment only to such degree that the sewage treatment
plant effluent cannot meet the requirements of other agencies having
jurisdiction over discharge to the receiving waters.
[CC 1984 §24.640]
A.
If any waters or wastes are discharged or are proposed to be discharged to the public sewers, which waters contain the substances or possesses the characteristics enumerated in Section 705.130 of this Article and which in the judgment of the Public Works Director may have a deleterious effect upon the sewage works, processes, equipment or receiving waters or which otherwise create a hazard to life to constitute a public nuisance, the Public Works Director 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/or
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 Section 705.190 of the Article.
|
|
If the Public Works Director permits the pretreatment or equalization
of waste flows, the design and installation of the plants and equipment
shall be subject to the review and approval of the Public Works Director
and subject to the requirements of all applicable codes, ordinances
and laws.

[CC 1984 §24.650]
Grease, oil and sand interceptors shall be provided when, in
the opinion of the Public Works Director, they are necessary for the
proper handling of liquid wastes containing grease in excessive amounts
or any flammable wastes, sand or other harmful ingredients, except
that such interceptors shall not be required for private living quarters
or dwelling units. All interceptors shall be of a type and capacity
approved by the Public Works Director and shall be located as to be
readily and easily accessible for cleaning and inspection.
[CC 1984 §24.660]
Where preliminary treatment or flow-equalizing facilities are
provided for any waters or wastes, they shall be maintained continuously
in satisfactory and effective operation by the owner at his/her expense.
[CC 1984 §24.670]
When required by the Public Works Director, 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 Public Works Director. 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.
[CC 1984 §24.680]
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 said control manhole. In
the event that 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
or samples 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.)
[CC 1984 §24.690]
No statement contained in this Article 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 therefore, by the industrial concern.
[CC 1984 §24.760]
No unauthorized person shall maliciously, willfully or negligently
break, damage, destroy, uncover, deface or tamper with any structure,
appurtenance or equipment which is part of the sewage works.
[CC 1984 §24.770]
The Public Works Director and other duly authorized employees
of the City bearing proper credentials and identification shall be
permitted to enter all properties for the purposes of inspection,
observation, measurement, sampling and testing in accordance with
the provisions of this Article. The Public Works Director or his/her
representatives shall have no authority to inquire into any processes
including metallurgical, chemical, oil, refining, ceramic, paper or
other industries beyond that point having a direct bearing on the
kind and source of discharge to the sewers or waterways or facilities
for waste treatment.
[CC 1984 §24.780]
While performing the necessary work on private properties referred to in Article IV, Section 705.210 above, the Public Works Director or duly authorized employees of the City shall observe all safety rules applicable to the premises established by the company and the company shall be held harmless for injury or death to the City employees and the City shall indemnify the company against loss or damage to its property by City employees and against liability claims and demands for personal injury or property damage asserted against the company and growing out of the gauging and sampling operation, except as such may be caused by negligence or failure of the company to maintain safe conditions.
[CC 1984 §24.790]
The Public Works Director and other duly authorized employees
of the City bearing proper credentials and identification shall be
permitted to enter all private properties through which the City holds
a duly negotiated easement for the purposes of, but not limited to,
inspection, observation, measurement, sampling, repair and maintenance
of any portion of the sewage works lying within said easement. All
entry and subsequent work, if any, on said easement shall be done
in full accordance with the terms of the duly negotiated easement
pertaining to the private property involved.
