No person shall discharge, or cause to be discharged, any stormwater,
surface water, groundwater, roof runoff, including downspouts, subsurface
drainage, including foundation drains, 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 Village, 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 sewer:
A. Any gasoline, benzene, naptha, fuel oil, or other flammable or explosive
liquid, solids, 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.
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 the sewer, 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 sewer, 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 sewer, materials of construction
of the sewer, nature of the sewage treatment process, capacity of
the sewage treatment plant, degree of treatability of wastes in the
sewage treatment plant, and maximum limits established by regulatory
agencies. The substances prohibited are:
A. Any liquid or vapor having a temperature higher than 150° F.
(65° C.).
B. Any waters or wastes containing toxic or poisonous materials; or
oils, whether emulsified or not, in excess of 100 mg/l or containing
substances which may solidify or become viscous at temperatures between
32° F. and 150° F. (0° C. 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 hp metric) or greater shall be subject to the review
and approval of the Village.
D. Any waters or wastes containing strong acid, iron pickling wastes,
or concentrated plating solution, whether neutralized or not.
E. Any waters or wastes containing iron, chromium, copper, zinc, or
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 Village for such materials.
F. Any waters or wastes containing phenols or other taste- or odor-producing
substances, in such concentration exceeding limits which may be established
by the Village 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 Village in compliance with
applicable state or federal regulations.
H. Any mercury or any of its compounds in excess of 0.0005 mg/l as Hg
at any time except as permitted by the Village in compliance with
applicable state and federal regulations.
I. Materials which exert or cause:
(1)
Unusual concentrations of inert suspended solids (such as, but
not limited to, Fullers 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 concentrations of wastes constituting
"slugs" as defined herein. (Reference Appendix #7.)
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 agencies having jurisdiction
over discharge to the receiving waters.
K. Any waters or wastes having a pH in excess of 9.5.
L. Any cyanide in excess of 0.025 mg/l at any time except as permitted
by the Village in compliance with applicable state and federal regulations.
Where preliminary treatment or flow-equalizing facilities are
provided, they shall be maintained continuously in satisfactory and
effective operation by the owner at his expense.
Each industry shall be required to install a control manhole
and, when required by the Sewer District, 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 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 4 shall
be determined in accordance with the latest edition of IEPA Division
of Laboratories Manual of Laboratory Methods, and shall be determined
at the control manhole provided or upon suitable samples taken at
the 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 pHs are determined from periodic
grab samples.)
No statement contained in this Part
4 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, in accordance with this Part
4, by the industrial concern, provided such payments are in accordance with federal and state guidelines for a user charge system and industrial cost recovery system. (See Part
4, Article
I of this chapter.)
