§29-131]
A.
No person
shall discharge or cause to be discharged to the public sewers the
following described substances, materials, waters, or wastes, if in
the opinion of the City Administrator such wastes can harm the sewer,
sewage treatment process or equipment, have 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 City Administrator 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 and other pertinent factors. Prohibited substances are:
1.
Any
liquid or vapor having a temperature higher than one hundred fifty
degrees Fahrenheit (150°F).
2.
Any
water or waste containing fats, wax, grease or oils, whether emulsified
or not in excess of one hundred (100) milligrams per liter or containing
substances which may solidify or become discernibly viscous at temperatures
between thirty-two and one hundred fifty degrees Fahrenheit (32°F
and 150°F).
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 City Administrator.
4.
Any
waters or wastes containing acid iron pickling wastes or concentrated
plating solutions whether neutralized or not.
5.
Any
noxious or malodorous substance which can form a gas, which either
singly or by interaction with other wastes is capable of causing objectionable
odors; or hazard to life or form solids in concentrations exceeding
limits established herein; or creates any other condition deleterious
to structures, treatment processes or equipment; or requires unusual
provisions, attention or expense to handle such materials.
6.
Any
water or wastes containing phenols in excess of 0.5 parts per million
or other taste- or odor-producing substances in such concentrations
exceeding such limits as may be set by the City Administrator as necessary,
after treatment of composite sewage, to meet the requirements of the
State, Federal or other public agencies or jurisdiction for such discharge
to receiving waters.
7.
Any
radioactive wastes or isotopes of such half-life or concentration
as may exceed limits established by the City Administrator in compliance
with applicable State and Federal regulations.
8.
Any
waters or wastes having a pH in excess of 10.5.
9.
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 the State, Federal or other agencies
having jurisdiction over discharge to receiving waters.
[R.O. 2008 §710.430; Code 1968 §28-39; CC 1988
§29-132]
A.
Except
in quantities or concentrations, or with provisions as stipulated
herein, it shall be unlawful for any person to discharge or cause
to be discharged waters or wastes to the public sewers containing:
1.
Free
or emulsified oil and grease exceeding, on analysis, an average of
one hundred (100) parts per million (eight hundred thirty-three (833)
pounds per million gallons) of either or both or combinations thereof,
if in the opinion of the City Administrator it appears probable that
such wastes can deposit grease or oil in the sewer lines in such a
manner as to produce clogging or can have deleterious effects on the
treatment process due to the excessive quantities.
2.
Salts
of heavy metals in solution or suspension in concentrations exceeding
the following:
|
|
Chromium (Hexavalent)
|
5 parts per million
|
|
|
Chromium (Trivalent)

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
biochemical oxygen demand, chemical oxygen demand or chlorine demand
in excess of thirty (30) parts per million that will constitute a
significant load on the sewage treatment works.
d.
High
hydrogen sulfide content.
e.
Unusual
volume of flow or concentration of wastes constituting "slugs", as defined herein shall be pretreated to a concentration acceptable
to the City if such wastes can:
(1)
Cause damage to collection facilities;
(2)
Impair the process;
(3)
Incur treatment cost exceeding those of normal sewage; or
(4)
Render the water unfit for stream disposal or industrial use.
|
|
Where discharge of such wastes to a public sewer is not properly
pretreated or otherwise corrected, the City Administrator may reject
the wastes, terminate the sewer service or require control of the
quantities and rates of the discharge of such wastes.
|
B.
If the
City Administrator 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 City Administrator subject
to the requirements of all applicable Codes, ordinances and laws.
