No person shall discharge or provide a connection for discharging
or draining into any Sewer District sewer system or public sewer tributary
thereto any stormwater, surface water, groundwater, roof runoff, subsurface
drainage, uncontaminated cooling water, or unpolluted industrial process
water, nor drain any catch basin, lake, swamp, pond, swimming pool
or any other source of unpolluted or uncontaminated waters, except
with the permission of the Superintendent evidenced by properly issued
license or permit.
Except as hereinafter provided, no person shall discharge or
cause to be discharged, or allow to run, leak, or escape into any
public sewer, pipe, channel, sewer appurtenance or waterway connecting
with any public sewer, or into any private sewer connected with a
public sewer, any of the following described materials, substances
or wastes:
A. Any gasoline, benzine, naptha, fuel oil, alcohols, or flammable or
explosive liquid, solids or gases.
B. Any water or wastes having a pH lower than 5.5 or having a pH higher
than 10.0 or having any other corrosive property capable of causing
damage or hazard to structures, equipment or the sewer system, or
personnel employed in its operation.
C. Any waters or wastes containing toxic or poisonous solids, liquids
or gases.
D. Construction materials, ashes, cinders, sand, mud, straw, shavings,
metal, glass, rags, feathers, tar, plastic, wood, paunch manure, coffee
grounds, fur, wax, cement, hops, spent grain, whole blood, fetus,
products of an abortion, surgical specimens, hair fleshing, entrails,
paper dishes, cups and milk containers, either whole or ground by
garbage grinders, filter media or any solids or viscous substances
capable of causing obstruction to the flow in sewers or other interferences
with the proper operation of the sewer system.
E. Any waters or wastes containing toxic or poisonous solids, liquids
or gases in sufficient quantity, either single or by interaction with
other wastes, to injure or interfere with any sewage treatment process,
or to constitute a hazard to humans or animals, or to create a public
nuisance, or to create any hazards in the receiving waters of a sewage
treatment plant effluent.
F. Any waters or wastes which are not in compliance with federal standards
promulgated pursuant to the Federal Water Pollution Control Act Amendments
of 1972 (FWPCAA), and/or any other federal and/or state standard for
water pollution control which is more stringent.
G. Any waters or wastes as defined in 40 CFR 128.131 of the Code of
Federal Regulations and as amended.
No person shall discharge or cause to be discharged the following
described substances, materials, waters or wastes or any wastes listed
within the rules of the Sewer District found to harm the trunk sewer,
interceptor sewers, system structures, a Sewer District sewer or public
sewer tributary thereto, the sewage treatment process or the equipment,
have an adverse effect on the receiving stream or endanger life, limb,
public property, or constitute a nuisance. The criteria used in forming
the rules of the Sewer District include such factors as the quantities
of said wastes in relation to flows and velocities in the sewers,
materials of construction of the sewers, nature of the sewage treatment
process, the capacity of the sewage treatment facilities and the likelihood
of harm, injury or nuisance. The characteristics of the effluent subject
to review will be determined from the sampled wastewater collected
at a control manhole prior to entering the public sewers. The substances,
materials or wastes prohibited in the first instance, but subject
to review by the Town are:
A. Any liquid or vapor having a temperature higher than 150° F.
(65° 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° and 150° F. (0° and 65° C.).
C. Any garbage that has not been properly shredded or triturated. The
installation and operation of garbage grinders equipped with a motor
greater than 3/4 horsepower (0.76 hp metric) shall be only by permit
issued by the Superintendent.
D. Any water or wastes containing strong acid, metal 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.
F. Any water or wastes containing phenols or other taste- or odor-producing
substances, in such concentrations exceeding limits which shall 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 of 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. Materials which contain 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 sulphate.
(2) Excessive discoloration at the treatment plant or in the receiving
waters, or in the sewage system, such as, but not limited to, dye
wastes and vegetable tanning solutions.
(3) Unusual biochemical oxygen demand (BOD), chemical oxygen demand (COD), or chlorine requirements in such quantities as to constitute a significant additional load on the sewage treatment works, except as provided for under Article
IX.
(4) Unusual volume of flow or concentration of wastes constituting "slugs,"
as defined herein.
I. Waters or wastes containing substances which are not amenable to
treatment or reduction in concentration by the sewage treatment plant
process employed, or are amenable to treatment only to such a degree
that the sewage treatment plant effluent cannot meet the requirements
of regulatory agencies having jurisdiction over discharge into the
receiving waters.
The Superintendent and Town Engineer, after a hearing, shall
either prevent the discharge of unacceptable water and wastes or issue
a license or permit which is properly conditioned upon findings and
the standards of safety prescribed by this chapter or the rules of
the Sewer District. The rules of the Sewer District shall include
surcharges, pretreatment requirements and any measure or combination
of measures which are necessary to preserve the sewer system, its
structures and equipment, and the health, safety and well-being of
the employees, the community and the biota of the receiving waters.
Any discharge which, in the belief of the Superintendent, will
cause serious, imminent harm, injury or adverse effect on the sewer
system structures or equipment, or to any persons or to the biota
of the receiving water, the Superintendent shall take any temporary
action necessary to protect the public health, safety or welfare without
a prior hearing or order of the Town Board. Review of any emergency
action by a hearing will be accomplished without delay to determine
what, if any, permanent restriction is necessary. The Superintendent
acting upon belief that an emergency exists shall be indemnified against
any personal liability that may arise in the performance of his or
her duties to protect the public health, safety or welfare of the
Town.
Waters bearing toxic substances above the standard set for normal
sewage or pathogenic bacteria shall not be discharged into the public
sewers, and their discharge is prohibited unless the rules of the
Sewer District or, upon a finding by the Town Board, it determines
that such concentration will not adversely affect any of the biochemical,
chemical or other sewage treatment process or sewage system. The following
is a partial list of toxic substances and pathogenic bacteria:
B. Elemental bromine, iodine, chlorine, fluorine.
D. Phenol and phenolic compounds that convert to phenol in the sewage
system.
E. Sulfonamides, toxic dyes (organic or mineral).
F. Berylium and berylium compounds.
G. Mercury and mercury compounds.
H. All strong oxidizing agents such as chromates, dichromates, permanganates,
peroxides, etc.
I. Any strong reducing agents causing hazardous conditions in the sewage
system.
J. Chemical compounds producing toxic, flammable or explosive gases,
either upon acidification, alkalinization, oxidation, or reduction.
K. Wastes from industrial processes or hospital procedures containing
viable pathogenic organisms.
The concentration in sewage of any of the following toxic substances
shall not exceed the concentration limits specified below when discharged
into the public sewers. The Sewer District may revise with its rules
these limits or insert additional items after a hearing when, in the
opinion of the Superintendent, the Department of Health or the Town
Board, the need for a rule change is indicated. The following list
contains the permitted toxic substances and levels of concentration:

NOTE:

Federal limits for any of the above toxic substances, if more
stringent, shall govern.

When the findings of the Superintendent, Town Engineer, and/or
Town Board show that the volume of a single toxic industrial waste
discharge or combined toxic industrial waste discharge of a group
of industries within a single contributory area is so large as to
raise a question of the ultimate concentration of toxic substances
entering a treatment plant, or in cases where it is known that the
toxic substances in concentrations involved will be removed by treatment
works without causing deleterious effects of any kind to the treatment
process or the receiving waters, the Superintendent, Town Engineer,
and/or Town Board may rule that separate or special concentration
limits shall be used by the contributors in that area.
Any discharge which, in the belief of the Superintendent, will
cause serious, imminent harm, injury or adverse effect on the sewer
system structures or equipment or to any persons or to the biota of
the receiving waters, the Superintendent shall take any temporary
action necessary to protect the public health, safety or welfare without
a prior hearing or order of the Town Board. Review of any emergency
action by a hearing will be accomplished without delay to determine
what, if any, permanent restriction is necessary. The Superintendent,
acting upon the belief that an emergency exists, shall be indemnified
against any personal liability that may arise in the performance of
his duties to protect the public health, safety or welfare of the
Town.
