[Code 1975, § 19-4(a), (b)]
(a) No person shall discharge or cause to be discharged any of the following
described waters or wastes to any public sewers or drains:
(1)
Any gasoline, benzene, naphtha, fuel oil, or other flammable
or explosive liquid, solid or gas.
(2)
Any pollutants, including, without limitation, oxygen demanding
pollutants, either singly or by interaction with other wastes, in
sufficient quantity to injure or interfere with any wastewater treatment
process, constitute a hazard to humans or animals, create a public
nuisance, or are not susceptible to treatment or which may interfere
with the biological processes or efficiency of the treatment system,
or that will pass through the system or create any hazard in the receiving
waters of the wastewater treatment plant or causing any other interference.
(3)
Any acidic waters or wastes having a pH lower than 5.0, or having
any other corrosive property capable of causing damage or hazard to
structures, equipment and personnel of the wastewater works. Prohibited
materials include, but are not limited to, acids, sulfides, concentrated
chloride and fluoride compounds and substances which will react with
water to form acidic products.
(4)
Solid or vicious substances in quantities or of such size as
would be capable of causing obstruction to the flow in sewers, or
other interference with the proper operation of the wastewater 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, unless approved in writing by the Director.
(5)
Any liquid or vapor having a temperature higher than 140°
F. (60° C.); provided, that such discharges do not result in a
temperature at the plant influent greater than 104° F. (40°
C.). In such cases where the 104° F. (40° C.) influent criterion
is violated, the temperature of the wastewater from the industrial
user shall be lowered to a point that will be determined by the Director.
[Amended 10-5-2010 by Ord. No. 2010.100]
(6)
National categorical pretreatment standards as promulgated by
the U.S. Environmental Protection Agency (EPA) pursuant to the act
shall be met by all dischargers. An application for modification of
the national categorical pretreatment standards may be considered
for submittal to the regional administrator by the City when the City's
wastewater treatment system achieves consistent removal of the pollutants
as defined by 40 CFR 403.7.
(b) 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 Director that such wastes can harm either the
sewers, wastewater treatment process or equipment, have an adverse
effect on the receiving stream, or can otherwise endanger life, limb,
or public property, or constitute a nuisance. In forming his opinion
as to the acceptability of these wastes, the 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 wastewater treatment process, capacity of the
wastewater treatment plant, degree of treatability of wastes in the
wastewater treatment plant, and other pertinent factors. The substances
prohibited are:

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).
[Amended 10-5-2010 by Ord. No. 2010.100]
b.
Color or turbidity in such an amount that it will prevent the
City from discharging a treated effluent in compliance with the water
quality standards.
c.
Unusual BOD, chemical oxygen demand or chlorine requirements
in such quantities as to constitute a significant load on the wastewater
treatment plant.
d.
Unusual volume of flow or concentration of wastes constituting
slugs.
(8)
Waters or wastes containing substances which are not amenable
to treatment or reduction by the sewage treatment plant 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 containing organic compounds such as volatile organics,
semivolatile organics, pesticides and similar hazardous or toxic substances
to such a degree that any such material received in the composite
wastewater at the wastewater treatment plant exceeds the limits established
by the Director for such materials.
(12)
Any noxious or malodorous liquids, gases or solids which, either
singly or by interaction, are capable of creating a public nuisance
or hazard to life or are sufficient to prevent entry into the sewers
for their maintenance and repair.
(13)
Any substance which may cause the City's wastewater facilities
effluent or residues, sludges or scums to be unsuitable for reclamation
and reuse or to interfere with the reclamation process.
(14)
