Except as expressly hereinafter provided, 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 interacting 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
or 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 sewer.
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 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, 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.
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 Superintendent, 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 or public property or constitute a nuisance. In forming
his opinion as to the acceptability of these wastes, the Superintendent
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, the 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° F.
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 [zero and 0.76 horsepower metric] or greater
shall be subject to the review and approval of the Superintendent.
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 Superintendent for such materials.
F. Any waters or wastes containing phenols or other taste-
or odor-producing substances in such concentrations exceeding limits
which may be established by the Superintendent, as necessary, after
treatment of the composite sewage to meet the requirements of the
state, federal and 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 Superintendent
in compliance with applicable state and federal regulations.
H. Any waters or wastes having a pH in excess of 9.5.
I. Materials which exert or cause:
(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 chloride
and 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 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.
[Amended 12-14-1993 by L.L. No. 3-1993]
A. If any waters or wastes are discharged or are proposed to be discharged to public sewers, which waters contain the substances or possess the characteristics enumerated in §
118-21 of this article and which, in the judgment of the Superintendent, 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 Superintendent may:
(2) Require pretreatment to an acceptable condition for
discharge to the public sewers;
(3) Require control over the quantities and rates of discharge;
and/or
(4) Require payment to cover the added costs of handling and treating of the waste not covered by existing taxes or sewer charges under the provisions of §
118-27 of this article.
B. If the Superintendent permits the pretreatment or
equalization of waste flows, the design and insulation of the plants
and equipment shall be subject to the review and approval of the Superintendent
and subject to requirements of all applicable codes, ordinances and
laws.
Grease, oil and sand interceptors shall be provided
when, in the opinion of the Superintendent, 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 a type and capacity
approved by the Superintendent and shall be located so 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 Superintendent, 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 Superintendent.
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 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 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.)
No statement contained in this article shall
be construed as preventing any special agreement or arrangement between
the Village and any industrial concern whereby any industrial waste
of unusual strength or character may be accepted by the Village for
treatment, subject to payment therefor by the industrial concern.
