§ 162-8. Exclusion of
unpolluted waters.
No person
shall discharge or cause to be discharged into any Village or county trunk
sewer systems or public sewer tributary thereto any stormwater, surface water,
groundwater, roof runoff, subsurface drainage, uncontaminated cooling water, or
unpolluted industrial process waters except as provided in Article IV hereof.
§ 162-9. Prohibit
materials, substances and wastes.
Except as
hereinafter provided no person shall discharge or cause to be discharged into
any Village or county trunk sewer systems or public sewer tributary thereto, or
any private sewer connecting with a public sewer, any of the following
materials, substances or wastes:
A. Any
gasoline, benzine, 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 as
provided in Article VI.
C. Any
water or wastes having a pH lower than 4.5 or having a pH higher than 10.0, or
having any other corrosive property capable of causing damage or hazard to
structures, equipment of the sewer system, or personnel employed in its
operation.
D. Solid
or viscous substances in quantities or of such size or state 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, tar, plastics, wood, unground
garbage, whole blood, paunch manure, feathers, hair and fleshings, entrails,
paper dishes, cups, milk containers, etc., either whole or ground by garbage
grinders.
E. 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, 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.
§ 162-10. Possible
exclusion of certain materials and substances.
No person
shall discharge or cause to be discharged the following described substances,
materials, waters or wastes unless it appears in the opinion of the County
Commissioner and Superintendent that such wastes cannot harm the trunk sewer
system structures, sewage treatment process or equipment, have an adverse
effect on the receiving stream or could otherwise endanger life, limb, public
property, or constitute a nuisance. In forming his opinion as to the
acceptability of these wastes, the County Commissioner and 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 and capacity of the sewage
treatment facilities. The substances, materials or wastes prohibited in the
first instance but subject to review by the County Commissioner and
Superintendent 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 mg/l, 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 of 3/4 horsepower
(0.76 hp metric) or greater shall be subject to the review and approval of the
County Commissioner and 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 may be established by the County
Commissioner or Superintendent as necessary, after treatment of the composite
sewage to meet the requirements of the state, federal or other public agencies
or 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 County Commissioner or 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 sulfate.
(2) Excessive
discoloration at the treatment plant or in the receiving waters 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 VII.
I. Waters
or wastes containing substances which are not amenable to treatment or
reduction in concentration by the sewage treatment plant processes 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 to the receiving waters.
§ 162-11. Action by the
County Commissioner or Superintendent.
If any
waters or wastes are discharged or are proposed to be discharged to the Village
or county trunk sewers or public sewers tributary thereto, which waters contain
the substances or the characteristics enumerated in § 162-10 of this
article, and which, in the judgment of the County Commissioner or
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 County Commissioner or Superintendent
may:
A. Reject
the waters or wastes;
B. Require
pretreatment to an acceptable condition for discharge to the public
sewers;
C. Require
control over the quantities and rates of discharge; and/or
D. Require
payment to cover the added cost of handling and treating the waters or wastes
not covered by existing taxes or sewer charges.
