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.
A.
These general prohibitions apply to all users of the
POTW, whether or not the user is subject to national categorical pretreatment
standards or any other national, state or local pretreatment standards
or requirements.
B.
A user may not contribute the following substances
to the POTW:
(1)
Any liquids, solids or gases which by reason of their
nature or quantity are, or may be, sufficient either alone or by interaction
with other substances to cause fire or explosion or be injurious in
any other way to the POTW or to the operation of the POTW. At no time
shall two successive readings on an explosion hazard meter, at the
point of discharge into the system (or at any point in the system),
be more than 5% nor any single reading over 10% of the lower explosive
limit (LEL) of the meter. Prohibited materials include, but are not
limited to, gasoline, kerosene, naphtha, benzene, toluene, xylene,
ethers, alcohols, ketones, aldehydes, peroxides, chlorates, perchlorates,
bromates, carbides, hydrides and sulfides and any other substances
which the Village, the state or the EPA has notified the user is a
fire hazard or a hazard to the system.
(2)
Solid or viscous substances which may cause obstruction
to the flow in a sewer or other interference with the operation of
the POTW treatment plant, such as but not limited to grease, garbage
with particles greater than 1/2 inch in any dimension, animal guts
or tissues, paunch manure, bones, hair, hides or fleshings, entrails,
whole blood, feathers, ashes, cinders, sand, spent lime, stone or
marble dust, metal, glass, straw, shavings, grass clippings, rags,
spent grains, spent hops, waste paper, wood, plastics, gas, tar, asphalt
residues, residues from refining or processing or fuel or lubricating
oil, mud or glass-grinding or -polishing wastes.
(3)
Any wastewater having a pH less than 5.5 or greater
than 8.5, or wastewater having any other corrosive property capable
of causing damage or hazard to structures, equipment and/or personnel
of the POTW.
(4)
Any wastewater containing toxic pollutants in sufficient
quantity, either singly or by interaction with other pollutants, to
injure or interfere with any wastewater treatment process, constitute
a hazard to humans or animals, create a toxic effect in the receiving
waters of the POTW or exceed the limitations set forth in a categorical
pretreatment standard. A toxic pollutant shall include but not be
limited to any pollutant identified pursuant to Section 307(a) of
the Act.
(5)
Any noxious or malodorous liquids, gases or solids
which, either singly or by interaction with other wastes, are sufficient
to create a public nuisance or hazard to life or are sufficient to
prevent entry into the sewers for maintenance or repair.
(6)
Any substance which may cause the POTW's effluent
or any other product of the POTW, such as residues, sludges or scums,
to be unsuitable for reclamation and reuse or to interfere with the
reclamation process. In no case shall a substance discharged to the
POTW cause the POTW to be in noncompliance with sludge use or disposal
criteria, guidelines or regulations developed under Section 405 of
the Act; any criteria, guidelines or regulations affecting sludge
use or disposal developed pursuant to the Solid Waste Disposal Act,
the Clean Air Act, the Toxic Substances Control Act or state criteria
applicable to the sludge management method being used.
(7)
Any substance which will cause the POTW to violate
its SPDES permit or the receiving water quality standards.
(8)
Any wastewater with objectionable color not removed
in the treatment process, such as but not limited to dye wastes and
vegetable tanning solutions.
(9)
Any liquid having temperature higher than 150º
F. or having a temperature which will inhibit biological activity
in the POTW treatment plant resulting in interference, but in no case
wastewater with a temperature at the introduction into the POTW treatment
plant which exceeds 104º F.
(10)
Any pollutants, including oxygen demanding pollutants
(BOD, etc.), released at a flow rate and/or pollutants concentration
which a user knows or has reason to know will cause interference to
the POTW. In no case shall a slug load have a flow rate or contain
concentration or qualities of pollutants that exceed for any time
period longer than 15 minutes more than five times the average 24-hour
concentration, quantities or flow during normal operation.
(11)
Any wastewater containing 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.
(12)
Any wastewater which causes a hazard to human
life or creates a public nuisance.
(13)
Stormwater, surface water, groundwater, roof
runoff, subsurface drainage, uncontaminated cooling water or unpolluted
industrial process water.
C.
When the Superintendent determines that a user(s)
is contributing to the POTW any of the above-enumerated substances
in such amounts as to interfere with the operation of the POTW, the
Superintendent shall advise the user(s) of the impact of the contribution
on the POTW and develop effluent limitation(s) for such user to correct
the interference with the POTW or may order the user(s) to cease and
desist the objectionable discharge.
A.
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, POTW 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 POTW treatment plant, degree of treatability of wastes
in the POTW treatment plant and other pertinent factors. The substances
prohibited are:
(1)
Any waters or wastes containing fats, wax, grease
or oils, whether emulsified or not, in excess of 100 mg/l or containing
substances which may solidify or become viscous at temperatures between
32º and 150º F. (0º and 65º C.).
(2)
Any garbage, shredded or otherwise.
(3)
Any waters or wastes containing acid-pickling wastes
or concentrated plating solutions.
(4)
Any waters or wastes containing iron, chromium, copper,
zinc and similar objectionable or toxic substances or wastes exerting
an excessive chlorine requirement to such a degree that any such material
received at the plant or into the sewer or as discharged from the
industry exceeds the limits established by the Superintendent. The
following are the limits which may not be exceeded for industrial
wastes at the point of entry into the public system:

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 having jurisdiction for such discharge to the receiving waters.
(6)
Materials which exert or cause unusual concentrations
of inert suspended solids, such as but not limited to diatomaceous
earth, Fuller's earth, lime slurries and lime residues; or of dissolved
solids, such as but not limited to sodium chloride and sodium sulfate.
B.
Upon the promulgation of the national categorical
pretreatment standards for a particular industrial subcategory, the
national standard, if more stringent than limitations imposed under
this Sewer Code for sources in that subcategory, will immediately
supersede the limitations imposed under this Sewer Code. The Superintendent
shall notify all affected users of the applicable reporting requirements
under 40 CFR 403.12. Users shall provide necessary wastewater treatment
as required to comply with this Sewer Code and shall achieve compliance
with all national categorical pretreatment standards within the time
limitations as specified by the national pretreatment regulations.
No mechanism or device for the disposal of garbage,
certain types of which are known as "garbage disposer," "garbage grinder"
or "food waste shredder," which is designed or intended or operates
to shred, grind, pulverize or otherwise decompose or dispose of garbage,
shall be installed in such a way that it can discharge directly or
indirectly into the public sewer. No permit for such installation
shall be granted.
A.
If any waters or wastes are discharged or are proposed to be discharged to the public sewers, which waters contain the substances or possess the characteristics enumerated in § 162-34 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:
B.
If the Superintendent permits the pretreatment or
equalization of waste flows, the design and installation of the plants
and equipment shall be subject to the review and approval of the Superintendent
and subject to the requirements of all applicable codes, ordinances
and laws.
C.
Upon the promulgation of the national categorical
pretreatment standards for a particular industrial subcategory, the
national standard, if more stringent than limitations imposed under
this Sewer Code for sources in that subcategory, will immediately
supersede the limitations imposed under this Sewer Code. The Superintendent
shall notify all affected users of the applicable reporting requirements
under 40 CFR 403.12. Users shall provide necessary wastewater treatment
as required to comply with this Sewer Code and shall achieve compliance
with all national categorical pretreatment standards within the time
limitations as specified by the national pretreatment regulations.
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 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 POTW 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 an industrial waste
of unusual strength or character may be accepted by the Village for
treatment, subject to payment therefor, by the industrial concern.
