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 combined sewers or 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, combined sewer or natural outlet. The SPDES requires that
persons discharging cooling water must apply for a SPDES permit and are subject
to state and federal regulations.
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 milligrams per liter as CN in the wastes as discharged
to the public sewer.
C. Any waters or wastes having a pH lower than five point
five (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 or 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, plastics, wood, unground garbage, whole blood, paunch manure, hair and
fleshings, entrails and paper dishes, cups, milk containers, etc., either
whole or ground by garbage grinders.
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 waste can harm either the sewers, sewage
treatment process or equipment, having 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 sewage treatment plant, degree of treatability of wastes in the sewage
treatment plant and other pertinent factors. The substances prohibited are:
A. Any liquid or vapor having a temperature higher than
150° F. (65° C.) or that will cause the influent to the POTW treatment
plant to be in excess of 104° F. (40° 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 thirty-two
degrees and one hundred fifty degrees Fahrenheit (32° and 150° F.)
[zero degrees and sixty-five degrees Celsius (0° and 65° C.)].
C. Any garbage that has not been properly shredded. The
installation and operation of any garbage grinder equipped with a motor of
three-fourths (3/4) horsepower [seventy-six hundredths (0.76) horsepower metric]
or greater shall be subject to the review and approval of the Superintendent.
D. Any waters or wastes containing strong acid iron pickling
wastes or concentrated plating solutions, whether neutralized or not.
E. Any water or wastes containing iron, chromium, copper,
zinc and similar objectionable or toxic substances; or wastes exerting an
excessive chlorine requirement, to such degree that any such material received
in the composite sewage at the sewage treatment works exceeds the limits established
by the Superintendent for such materials.
F. 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.
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. Any waters or wastes having a pH in excess of nine point
five (9.5).
I. Materials which exert 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, such as but not limited to dye
wastes and vegetable tanning solutions.
(3) Unusual BOD, chemical oxygen demand or chlorine requirements
in such quantities as to constitute a significant load on the sewage treatment
works.
(4) Unusual volume of flow or concentration of wastes constituting
"slugs" as defined herein.
J. 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.
Grease, oil and sand interceptors shall be provided when, in the opinion
of the Superintendent, they are necessary for the proper handling of liquid
waste 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 Part 1 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 the constituents upon the sewage works and to determine the existence
of hazards to life, limb and property. (The particular analysis 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 town, the Village of Churchville
and any industrial concern whereby an industrial waste of unusual strength
or character may be accepted by the town and Village of Churchville for treatment,
subject to payment therefor, by the industrial concern. However, no special
agreement shall circumvent federal categorical pretreatment standards.
