12.103 Art. V § 4, 5-19-1988]
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 Superintendent 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,

and 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 Superintendent for such materials.
6.
Any waters or wastes containing phenols or other taste or odor
producing substances, in such concentrations exceeding limits which
may be established by the Superintendent 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 Superintendent in compliance
with applicable State or Federal regulations.
8.
Any waters or wastes having a pH in excess of nine point five
(9.5).
9.
Materials which exert or cause:
a.
Unusual concentrations of inert suspended solids (such as, but
not limited to, Fullers earth, lime slurries, and lime residues) or
of dissolved solids (such as, but not limited to, sodium chloride
or sodium sulfate).
b.
Excessive discoloration (such as, but not limited to, dye wastes
and vegetable tanning solutions).
c.
Unusual BOD, biochemical 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.
11.
Any waters or wastes having:
a.
A five-day BOD greater than three hundred (300) parts per million
by weight; or
b.
Containing more than three hundred fifty (350) parts per million
by weight of suspended solids; or
c.
Having an average daily flow greater than two percent (2%) of
the average sewage flow of the City, shall be subject to the review
of the Superintendent.
12.
Where necessary in the opinion of the Superintendent, the owner
shall provide, at his/her expense, such preliminary treatment as may
be necessary to:
a.
Reduce the biochemical oxygen demand to three hundred (300)
parts per million by weight; or
b.
Reduce the suspended solids to three hundred fifty (350) parts
per million by weight; or
c.
Control the quantities and rates of discharge of such waters
or wastes. Plans, specifications, and any other pertinent information
relating to proposed preliminary treatment facilities shall be submitted
for the approval of the Superintendent and no construction of such
facilities shall be commenced until said approvals are obtained in
writing.
[R.O. 2003 § 710.280; Ord. No.
12.103 Art. V § 5, 5-19-1988]
A.
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 Section 710.270 of this Article, and which in the judgment of the Superintendent 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 Superintendent may:
B.
If the Superintendent 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 Superintendent,
and subject to the requirements of all applicable codes, ordinances
and laws.
[R.O. 2003 § 710.290; Ord. No.
12.103 Art. V § 6, 5-19-1988]
Grease, oil and sand interceptors shall be provided when, in
the opinion of the Superintendent, 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 Superintendent, and shall be located as to be readily
and easily accessible for cleaning and inspection.
[R.O. 2003 § 710.300; Ord. No.
12.103 Art. V § 7, 5-19-1988]
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.
[R.O. 2003 § 710.310; Ord. No.
12.103 Art. V § 8, 5-19-1988]
When required by the Superintendent, the owner of any property
services 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 Superintendent. 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.
[R.O. 2003 § 710.320; Ord. No.
12.103 Art. V § 9, 5-19-1988]
All measurements, tests and analyses of the characteristics
of waters and wastes to which reference is made in this Chapter 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-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-hour composites of all
outfalls whereas pH's are determined from periodic grab samples.)
[R.O. 2003 § 710.330; Ord. No.
12.103 Art. V § 10, 5-19-1988]
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 therefor, by the industrial concern.
