No persons shall discharge any stormwater, surface water, ground
water, roof runoff, subsurface drainage, including interior and exterior
foundation drains, other sources of surface runoff or ground water,
uncontaminated cooling water or uncontaminated or unpolluted industrial
process waters to any sanitary sewer.
[Ord. No. 2351, 10-21-2003]
Stormwater and all other unpolluted drainage shall be discharged
to such sewers as are specifically designated as storm sewers or to
a natural outlet approved by the Commissioner of Public Works. Industrial
cooling water or unpolluted process waters may be discharged on approval
of the Commissioner to a storm sewer or natural outlet.
[Ord. No. 2351, 10-21-2003]
A.
No
persons shall discharge or cause to be discharged any of the following
descried waters or wastes to any public sewers:
1.
Any gasoline, benzene, naphtha, fuel oil or other flammable or explosive
liquid, solid or gas. Pollutants which create a fire or explosive
hazard in the POTW including, but not limited to, wastestreams with
a closed-cup flashpoint of less than one hundred forty degrees Fahrenheit
(140°F) (sixty degrees Celsius (60°C)) using the test methods
specified in 40 CFR 261.21; any liquids, solids or gases which by
reason of their nature or quantity are or may be sufficient, either
alone or by interaction with other substances, to cause fire or explosion
or be injuries in any other way to the POTW or the operation of the
POTW. At no time, shall two (2) successive readings on a explosion
hazard meter at the point of discharge into the system (or at any
point in the system) be more than five percent (5%) nor any single
reading over ten percent (10%) of the lower explosive limit (LEL)
of the meter. Prohibited materials include, but are not limited to,
gasoline, kerosene, aldehydes, peroxides, chlorates, perchlorates,
bromates, carbides, hydrides and sulfides and any other substances
which the City, the State or EPA has notified the user is a fire hazard
or hazard to the system.
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 in the receiving waters of the sewage treatment
plant.
3.

[Ord. No. 2351, 10-21-2003]
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 Commissioner 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 an opinion as to the acceptability
of these wastes, the Commissioner 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. These substances prohibited are:
1.
Any liquid or vapor having a temperature higher than one hundred
fifty degrees Fahrenheit (150°F).
2.
Any water or wastes containing fats, wax, grease or oils, whether
emulsified or not, in excess of one hundred milligrams per liter (100
mg/l) or containing substances which may solidify or become viscous
at temperatures between thirty-two degrees Fahrenheit (32°F) and
one hundred fifty degrees Fahrenheit (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 (seventy-six hundredths (0.76) hp metric) or
greater shall be subject to the review and approval of the Commissioner.
Any institution, commercial or industrial that has large amounts daily
will be required to have on site a wet garbage removal.
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 Commissioner 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 Commissioner 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 Commissioner in compliance
with applicable State or Federal regulations.
8.
Any waters or wastes having a pH in excess of nine and one-half (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 or
sodium sulfate).
b.
Excessive discoloration (such as, but not limited to, dye wastes
and vegetable tanning solutions).
c.
Unusual BOD, chemical oxygen demand or chlorine requirements in such
quantities as to constitute a significant load on the sewage treatment
works.
d.
Unusual volumes of flow or concentration of wastes constituting "slugs"
as defined herein.
10.
Waters or wastes containing substances which are not menable 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 other agencies having jurisdiction
over discharge to the receiving waters.
11.
Any waters or wastes having (1) a five (5) day BOD greater than three
hundred (300) parts per million by weight, or (2) containing more
than three hundred fifty (350) parts per million by weight of suspended
solids, or (3) 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 Commissioner. Where necessary in the opinion of the
Commissioner, the owner shall provide, at his expense, such preliminary
treatment as may be necessary to (1) reduce the biochemical oxygen
demand to three hundred (300) parts per million by weight, or (2)
reduce the suspended solids to three hundred fifty (350) parts per
million by weight, or (3) 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 Commissioner and no construction
of such facilities shall be commenced until said approvals are obtained
in writing.
[Ord. No. 2602 §1, 11-18-2008]
In addition to any standards set forth elsewhere in this Article,
the applicable effluent limitations contained in Title 40 of the Code
of Federal Regulations, Part 437 (40 C.F.R. Part 437) shall apply
to discharges of industrial wastes and shall supplement other applicable
standards that may be set forth in this Article. Notwithstanding any
lesser limitations or standards for discharges of industrial wastes
that may be contained within this Article, any discharge of industrial
wastes in excess of the applicable effluent limitations contained
in 40 C.F.R. Part 437 shall also be a separate violation of this Article.
In the event any standards for discharges of industrial wastes set
forth elsewhere in this Article are more restrictive and are in conflict
with the effluent limitations referenced in this Section, the most
restrictive standard shall apply. However, irrespective of any more
restrictive standard that may be contained within this Article, the
applicable effluent standards referenced within this Section shall
constitute a minimum standard to which discharges of industrial wastes
must comply and no enforcement of any more restrictive standard shall
excuse compliance with the effluent limitations referenced in this
Section or preclude enforcement of such effluent limitations.
[Ord. No. 2351, 10-21-2003]
A.
If any waters or wastes are discharged or are proposed to be discharged to the public sewers, which waters containing the substances or possess the characteristics enumerated in Section 705.260 of this Article and which in the judgment of the Commissioner 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 Commissioner may:
1.
Reject the wastes,
2.
Require pretreatment to an acceptable condition for discharge to
the public sewers,
3.
Develop a discharge limit based on interference, pass through or
sludge contamination,
4.
Require control over the quantities and rates of discharge, and/or
5.
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 705.320 of the Article;
6.
Require more stringent limitations or requirements on discharges
to the wastewater disposal system;
7.
Require each user to provide protection from accidental discharge
of prohibited materials or other substances regulated by this Chapter.
Facilities to prevent accidental discharge or prohibited materials
shall be provided and maintained at the owner's or user's own cost
and expense. Detailed plans showing facilities and the operating procedures
to provide protection shall be submitted to the City for review and
shall be approved by the City before construction of the facility.
No user who commences contribution to the POTW after the effective
date of this Chapter shall be permitted to introduce pollutants into
the system until accidental discharge procedures have been approved
by the City. Review and approval of such plan and operating procedures
shall not relieve the industrial user from the responsibility to modify
the user's facility as necessary to meet the requirements to the Chapter.
In the case of an accidental discharge, it is the responsibility of
the user to immediately telephone and notify the POTW of the incident.
The notification shall include location of discharge, type of waste,
concentration and volume and corrective actions. If the Commissioner
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 Commissioner and subject to the requirements
of all applicable codes, ordinances and laws.
[Ord. No. 2351, 10-21-2003]
Grease, oil and sand interceptors shall be provided when required
by Code or otherwise, in the opinion of the Commissioner, they are
necessary for the proper handling of liquid wastes, sand or other
harmful ingredients and/or any type of slugs 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 Commissioner
and shall be located as to be readily and easily accessible for cleaning
and inspection, provided that any approved interceptor shall comply
with all applicable codes.
[Ord. No. 2351, 10-21-2003]
Where preliminary treatment of 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 expense.
[Ord. No. 2351, 10-21-2003]
When required by the Commissioner, 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 Commissioner. The manhole shall
be installed by the owner at his expense and shall be maintained by
him so as to be safe and accessible at all times. Testing will be
billed to the owner.
[Ord. No. 2351, 10-21-2003]
All measurements, tests and analyses of the characteristics
of waters and wastes to which reference is made in this Article 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 analysis
involved will determine whether a twenty-four (24) hour composite
of all outfalls or 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 composites
of all outfalls whereas pH analyses are determined from periodic grab
samples.)
[Ord. No. 2351, 10-21-2003]
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 therefore, by the industrial concern. Commercial and industrial
business in operation at the time of passage of this Article and have
grease traps, grease tanks, settling tanks, collector tanks or any
other form of tank or basin connected to the sanitary sewer system
shall have said traps and tanks, basins pumped as once every four
(4) months minimum or as required to meet the limits described herein
and supply a paid service ticket to the Commissioner of Public Works.
In the event the business does not have traps, tanks or basins pumped,
then the City will add an additional sewer charge of fifty dollars
($50.00) per month to the sewer bill.
