No person shall discharge or cause to be discharged
any stormwater, surface water, groundwater, roof runoff, subsurface
drainage, uncontaminated cooling water or unpolluted industrial process
waters to any sanitary sewer.
[Amended 2-8-1988 by L.L.
No. 1-1988]
Stormwater and all other unpolluted drainage
shall be discharged to such sewers as are specifically designated
as storm sewers or to an outlet approved by the Code Enforcement Officer
or the Village Engineer.
No person shall discharge or cause to be discharged
any of the following-described waters or wastes to any public sewers:
A. Any gasoline, benzene, naphtha, fuel oil or other
flammable or explosive liquid, solid or gas.
B. 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 milligrams per liter as CN in the wastes as discharged
to the public sewers.
C. Any waters or wastes having a pH lower than 5.5 or
having any other corrosive property capable of causing damage or hazard
to structures, equipment and personnel of the sewage works.
D. Solid or viscous substances in such quantities or
of such size as to be 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.
[Amended 2-8-1988 by L.L.
No. 1-1988]
No person shall discharge or cause to be discharged
the following-described substances, materials, waters or wastes if
it appears that such wastes may 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 establishing standards as to the acceptability of these
wastes, the Code Enforcement Officer or Village Engineer 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:
A. Any liquid or vapor having a temperature higher than
150° C.
B. Any water or waste containing fats, wax, grease or
oils, whether emulsified or not, in excess of 100 milligrams per liter,
or containing substances which may solidify or become viscous at temperatures
between 32° and 150° F. (0° and 65° C.).
C. Any garbage that has not been properly shredded. The
installation and operation of any garbage grinder equipped with a
motor of 3/4 horsepower (0.76 horsepower metric) or greater shall
be subject to the review and approval of the Code Enforcement Officer
or Village Engineer.
D. Any waters or wastes containing strong acid iron-pickling
wastes or concentrated plating solutions, whether neutralized or not.
E. 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 Board of Sewer Commissioners for such
materials.
F. Any waters or wastes containing phenols or other taste-
or odor-producing substances in such concentrations as exceed the
limits established by the Board of Sewer Commissioners 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.
G. Any radioactive wastes or isotopes of such half-life
or concentration as may exceed limits established by the Board of
Sewer Commissioners in compliance with applicable state or federal
regulations.
H. Any waters or wastes having a pH in excess of 9.5.
I. Materials which exert or cause the following:
(1) 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
sulfate.
(2) Excessive discoloration, such as but not limited to
dye wastes and vegetable tanning solutions.
(3) Unusual BOD, chemical oxygen demand or chlorine requirements
in such quantities as to constitute a significant load on the sewage
treatment works.
(4) Unusual volume of flow or concentration of wastes
constituting slugs, as defined herein.
J. Waters or wastes containing substances which are not
amenable to treatment or reduction by the sewage treatment process
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.
Grease, oil and sand interceptors shall be provided
when, in the opinion of the Village Engineer, 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 Village Engineer and shall be so located
as to be readily and easily accessible for cleaning and inspection.
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 expense.
When required by the Village Engineer, 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 accessible and safely located and shall be
constructed in accordance with the plans approved by the Village Engineer.
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.
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 edition of
Standard Methods for the Examination of Water and Wastewater, published
by the American Public Health Association, as in effect at the time
of the passage of this chapter, 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
analyses involved will determine whether a twenty-four-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-hour composites of all
outfalls, whereas pH's are determined from periodic grab samples.)
Nothing in this article shall be construed as
preventing any special agreement or arrangement between the Village
of Pomona and any industrial concern whereby an industrial waste of
unusual strength or character may be accepted for treatment subject
to payment therefor by the industrial concern in accordance with applicable
provisions of law. Any such agreement shall be reviewed by the Joint
Board and a report made prior to entering into such agreement. The
Joint Board may initiate such an agreement for approval by the Village
of Pomona.
