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.
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.
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
150º F. (65º 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 32º and
150º F. (0º and 65º 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.
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.
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.
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.
