No person shall discharge or cause to be discharged
any stormwater, surface water, ground water, 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 designed as
combined sewers or storm sewers, or to a natural outlet approved by
the Superintendent. Industrial cooling water or unpolluted process
water may be discharged, on approval of the Superintendent, 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 sewers:
A.
Any gasoline, benzene, 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 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, including but not limited to cyanides
in excess of two mg/liter as CN in the wastes as discharged to the
public sewer.
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 and viscous substances in quantities or of such
size 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, feathers, tar, paint, plastics, wood, unground garbage,
whole blood, paunch manure, hair and fleshings, entrails and paper
dishes, cups, milk containers and so forth, either whole or ground
by garbage grinders.
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, 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.
B.
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 sewage treatment plant,
degree of treatability of wastes in the sewage treatment plant, and
other pertinent factors. The substances prohibited are:
(1)
Any liquid or vapor having a temperature higher than
150º F. (65º C.) at the point of entrance into a public
sewer.
(2)
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 F. and 150º F. (0º C. and 65º C.).
(3)
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 horsepower metric) or greater shall
be subject to the review and approval of the Superintendent.
(4)
Any waters or wastes containing strong acid, iron-pickling
wastes, or concentrated plating solutions, whether neutralized or
not.
(5)
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 in the composite sewage at the treatment works exceeds
the limits established by the Superintendent for such materials.
(6)
Any waters or wastes containing phenols or other taste
or odor producing 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 of jurisdiction for such discharge
to the receiving waters.
(7)
Any radioactive wastes or isotopes of such half-life
or concentration as may exceed limits established by the Superintendent
in compliance with applicable state and/or federal regulations.
(8)
Any waters or wastes having a pH in excess of 9.5.
(9)
Materials which exert or cause:
(a)
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).
(b)
Excessive discoloration (such as, but not limited
to, dye wastes and vegetable tanning solutions).
(c)
Unusual BOD, chemical oxygen demand, or chlorine
requirements in such quantities as to constitute a significant load
on the sewage treatment works.
(d)
Unusual volume of flow or concentration of wastes
constituting "slugs" as defined herein.
(10)
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 other agencies having jurisdiction over discharge to the receiving
waters.
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 § 172-28 of this article, 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.
Grease, oil and sand interceptors shall be provided
when, in the opinion of the Plumbing Inspector, 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 Plumbing Inspector, 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 Plumbing Inspector, 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 Plumbing
Inspector. 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 Waste Water,"
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 server 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 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 premise
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.
