[CC 1983 §113.135; Ord. No. 96-04 §§710.280, 3-7-1996; Ord. No. 02-36, 9-19-2002]
A.
No
person shall discharge or cause to be discharged any of the following
described waters or wastes into 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, woods, unground garbage, whole blood, paunch
manure, hair and fleshings, whole or ground by garbage grinders.

[CC 1983 §113.140; Ord. No. 02-36, 9-19-2002]
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 Waste Water Plant Superintendent that such wastes can
harm either the sewers, sewage treatment process or equipment, having
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 Waste
Water Plant Superintendent will give consideration 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:

fifty degrees Fahrenheit (150°F) (sixty-five degrees centigrade
(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 (32) and one hundred fifty degrees Fahrenheit (150°F)
(zero (0) and sixty-five degrees centigrade (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 (0.76 hp metric) or greater shall be subject
to the review and approval of the Building Official.
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 Waste Water Plant 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 Waste Water Plant Superintendent as necessary after treatment
of the composite sewage, to meet the requirements of the 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 Waste Water Plant Superintendent
in compliance with applicable State or Federal regulations.
8.
Any waters or wastes having a pH in excess of ten and five-tenths
(10.5).
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).
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 waters 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 §113.145; Ord. No. 02-36, 9-19-2002]
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 Sections 710.290 of this Chapter 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 or constitute a public nuisance, the Public Works Director may:
B.
If
the Public Works Director permits the treatment or equalization of
waste flows, the design and installation of the plants and equipment
shall be subject to the review and approval of the Building Official
and subject to the requirements of all applicable codes, ordinances
and laws.
[CC 1983 §113.150; Ord. No. 02-10, 4-4-2002]
A.
Grease,
oil, and sand interceptors shall be provided when in the opinion of
the Building Official 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 Building
Official and shall be located as to be readily and easily accessible
for cleaning and inspection.
B.
Grease
interceptors shall be a minimum of one thousand (1,000) gallon capacity
in ground concrete baffled type unless an engineer's calculation shows
a smaller capacity is sufficient. This applies to all food service
businesses requiring grease traps or interceptors as well as other
businesses that will have grease-laden waste. Sand interceptors, oil
separators and other interceptors shall be sized to meet the requirements
of the International Plumbing Code and the responsible design professional.
[Ord. No. 16-09, 2-18-2016]
[CC 1983 §113.155]
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 §113.160; Ord. No. 02-36, 9-19-2002]
When required by the Public Works Director and Building Official,
the owner of any property served 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 Building
Official. 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 §113.165]
All measurements, tests, and analyses of the characteristics
of water 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 of 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.)
