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 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 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 waste 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.). Also, any liquid or vapor as influent to the POTW treatment
plant having a temperature higher than 104° F. (40° 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° F. and 150° F. (0° C. and 66° 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 wastes containing strong acid iron-pickling wastes
or concentrated plating solutions, whether neutralized or not.
E. Any water 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 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 solution).
(3) Unusual 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.
(5) BOD5 greater than 300 milligrams per liter
by weight.
(6) Suspended solids greater than 350 milligrams per liter by weight.
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 waste 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 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 Part 2 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 the 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 pHs 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. However, no
special agreement shall circumvent federal categorical pretreatment
standards.
The sewer use rates established by the Village Board, including
latest amendments, shall take precedence over any inconsistent agreements
between the Village and the users.
No person shall maliciously, willfully or negligently break,
damage, destroy, uncover, deface or tamper with any structure, appurtenance
or equipment which is a part of the sewage works.
