[CC 1983 §26-71; Ord. No. 472 Art. V §§1, 2, 2-25-1974]
A. No
person shall discharge or cause to be discharged any storm water,
surface water, groundwater, roof runoff, subsurface drainage, uncontaminated
cooling water, or unpolluted industrial process waters to any sanitary
sewer.
B. Storm
water and all other unpolluted drainage shall be discharged to such
sewers as are specifically designated as combined sewers or storm
sewers, or to a natural outlet approved by the Superintendent. Industrial
cooling water or unpolluted process waters may be discharged, on approval
of the Superintendent to a storm sewer, combined sewer or natural
outlet.
[CC 1983 §26-72; Ord. No. 472 Art. V §3, 2-25-1974]
A. No
person shall discharge or cause to be discharged any of the following
described waters or wastes to any public sewers:
1. Any gasoline, benzene, naphtha, fuel oil, or other flammable or explosive
liquid, solid, or gas.
2. Any waters or wastes containing toxic or poisonous solids, liquids,
or gases in sufficient quantity, either singly or by interaction with
other wastes, to injure or interfere with any sewage treatment process,
constitute a hazard to humans or animals, create a public nuisance,
or create any hazard in the receiving waters of the sewage treatment
plant, including but not limited to cyanides in excess of two (2)
mg/l as CN in the wastes as discharged to the public sewer.
3. Any waters or wastes having a pH lower than five and five-tenths
(5.5) or having any other corrosive property capable of causing damage
or hazard to structures, equipment, and personnel of the sewage works.
4. Solid or viscous substances in quantities or of such size capable
of causing obstruction to the flow in sewers, or other interference
with the proper operation of the sewage works such as, but not limited
to, ashes, cinders, sand, mud, straw, shavings, metal, glass, rags,
feathers, tar, plastics, wood, unground garbage, whole blood, paunch
manure, hair and fleshings, entrails and paper dishes, cups, milk
containers, etc., either whole or ground by garbage grinders.
[CC 1983 §26-73; Ord. No. 472 Art. V §4, 2-25-1974]
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, public
property or constitute a nuisance. In forming his/her opinion as to
the acceptability of these wastes, the Superintendent 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
substances which may solidify or become viscous at temperatures between
thirty-two degrees (32°) and one hundred fifty degrees Fahrenheit
(150°F) (zero (0) and sixty-five degrees Celsius (65°C).
3. Any garbage that has not been properly shredded. The installation
and operation of any garbage grinder equipped with a motor of three-fourths
(¾) horsepower or greater shall be subject to the review and
approval of the Superintendent.
4. Any waters or wastes containing strong acid iron pickling wastes,
or concentrated plating solutions whether neutralized or not.
5. Any waters or wastes containing iron, chromium, copper, zinc, 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 concentrates exceeding limits which may be established
by the Superintendent as necessary, after treatment of the composite
sewage, to meet the requirements of the State, Federal, or other public
agencies or 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 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 chloride and
sodium sulfate) containing more than three hundred fifty (350) parts
per million by weight of suspended solids.
b. Excessive discoloration (such as, but not limited to, dye wastes
and vegetable tanning solutions).
c. Unusual BOD, biochemical oxygen demand, greater than three hundred
(300) parts per million by weight, or chlorine requirements in such
quantities as to constitute a significant load on the sewage treatment
works.
d. An average daily flow greater than two percent (2%) of the average
sewage flow of the City, or an 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 1983 §26-74; Ord. No. 472 Art. V §5, 2-25-1974]
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
705.280 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 or constitute a public nuisance, the Superintendent may:
2. Require the owner, at his/her own expense, to provide such preliminary
treatment as may be necessary to reduce the BOD, biochemical oxygen
demand, to three hundred (300) parts per million and the suspended
solids to three hundred fifty (350) parts per million by weight,
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
705.340 of this Article.
B. If
the Superintendent permits the pretreatment or equalization of wastes
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.
[CC 1983 §26-75; Ord. No. 472 Art. V §6, 2-25-1974]
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.
[CC 1983 §26-76; Ord. No. 472 Art. V §7, 2-25-1974]
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 1983 §26-77; Ord. No. 472 Art. V §8, 2-25-1974]
When required by the Superintendent, 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 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.
[CC 1983 §26-78; Ord. No. 472 Art. V §9, 2-25-1974]
A. 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 such 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.
B. The
particular analyses involved will determine whether a twenty-four
(24) hour composite of all outfalls of a premise 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 composite of all outfalls whereas pH's are determined from
periodic grab samples.
[CC 1983 §26-79; Ord. No. 472 Art. V §10, 2-25-1974]
Nothing 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.
