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.
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 Superintendent.
Industrial cooling water or unpolluted process waters may be discharged,
on approval of the Superintendent, to a storm sewer or natural outlet.
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 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 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, 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, 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, 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. (65° C.).
B. Any water or waste containing fats, wax 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 Superintendent.
D. Any waters or waste 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 as may exceed
limits which may be established by the Superintendent 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 Superintendent
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:
(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.
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 of a type and
capacity approved by the Superintendent and shall be located as to
be readily and easily accessible for cleaning and inspection.
Where preliminary treatment or flow-equalizing
facilities are provided for any wastes or waters, 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 analysis 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 an industrial waste
of unusual strength or character may be accepted by the Village for
treatment, subject to payment therefor by the industrial concern.
[Added 1-6-1987 by L.L. No. 2-1987]
Industrial users shall comply with Section 307b
of the Federal Water Pollution Control Act amendments of 1972 concerning
pretreatment standards, where applicable.
