No person shall discharge into any public sewer
of the Town of Stony Point any waste, substance or waters other than
such kinds or types of waters or water-carried wastes for the conveyance
of which the particular public sewer is intended, designed or provided.
No person shall discharge or cause to be discharged
any stormwater, surface water, groundwater, roof runoff, subsurface
drainage, cooling water, air-conditioning and refrigerating wastewaters
or unpolluted industrial process waters to any sanitary sewer.
Stormwater and all other unpolluted drainage
or uncontaminated process water in excessive quantities shall be discharged
to storm sewers or to a natural outlet. Such waters shall be discharged
only after approval of any local, county or state regulatory agency
having jurisdiction.
[Amended 2-14-1984; 9-10-1985]
Except as hereinafter provided, no person shall
discharge or cause to be discharged any of the following described
waters or wastes to any public sewer. However, in the event of such
discharge, accidental or otherwise, its occurrence shall be immediately
reported to the town.
A. Any liquid or vapor having a temperature higher than
150º F. or which causes the influent to the plant to exceed 104º
F. (40º C.).
B. Any water or waste which may contain more than 100
milligrams per liter by weight of fat, oil, wax or grease or may contain
other substances which may solidify or become viscous at temperatures
between 32º F. and 150º F.
C. Any gasoline, kerosene, disinfectants, benzene, naphtha,
alcohol, tar, fuel oil or other flammable or explosive liquid, solid,
gas or vapor.
D. Any garbage except properly shredded garbage. The
installation and operation of any garbage grinder equipped with a
motor of 3/4 horsepower or greater shall be subject to the review
and approval of the Superintendent.
E. Any ashes, cinders, stones, sand, mud, straw, shavings
or sawdust, metal, sticks, coarse rubbish, glass, rags, tar, feathers,
plastics, waste rubber, animal guts or tissues, entrails, blood, hair,
hides, wood, paunch manure or any other substance likely to damage,
destroy or cause an obstruction to the flow in any sewer or which
may interfere with the proper operation of the sewage works.
F. Any waters, sewage or wastes having a pH lower than
5.0 or higher than 9.5 or having any other corrosive or detrimental
property capable of causing damage or hazard to the sewage works or
personnel.
G. Any waters or wastes containing a toxic, poisonous
or radioactive substance in sufficient quantity to injure or interfere
with any sewage treatment process or to constitute a hazard to humans,
animals or marine life or create any hazard in the receiving waters.
Radioactive wastes or materials may be discharged into a public sewer
if Conditions I and II below are met and if either Condition III or
IV is also met, provided that such discharges are in compliance with
applicable state or federal regulations.
(1) Condition I: Such wastes must be readily soluble or
dispersible in water.
(2) Condition II: The gross quantity of all radioactive
materials so discharged must not exceed one curie per year.
(3) Condition III: The daily quantity of any radioactive
material, if diluted by the average daily volume of sewage discharged
into the system from the installation, must not exceed the maximum
concentrations allowed by regulations of the United States Atomic
Energy Commission.
(4) Condition IV: Daily quantities of radioactive materials
up to the maximum permitted by the United States Atomic Energy Commission
may be so discharged, provided that the total monthly quantities,
if diluted by the average monthly volume of sewage discharged from
the installation, do not exceed the concentrations permissible under
Condition III above.
H. Any noxious, malodorous or taste-producing gas, vapor
or substance, such as phenols, which, either singly or by interaction
with other sewage, are capable of creating a public or private nuisance
or which may prove toxic to sewage treatment processes or which may
exceed acceptable limits for discharge to receiving waters.
I. Any waters or wastes containing phenols or other taste-
or odor-producing substances in such concentrations exceeding limits
which may be established by the United States Environmental Protection
Agency, 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.
J. It shall be unlawful for any individual or corporation
to discharge waters or wastes to the sanitary sewer containing metallic
ions and salts of heavy metals, in solution or suspension, in concentrations
exceeding the following, the analytical results to be expressed in
terms of the element indicated:

K. 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, suspended solids, 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.
L. 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.
In determining whether any waste discharged
or proposed to be discharged into any public sewer is to be excluded,
consideration will be given to the quantity, time or times, rate and
manner of discharge, dilution and character of the waste in question,
the size of the sewer into which the waste is to be discharged, the
probable quantity of sewage or other wastes likely in said sewer and
other pertinent facts. Minute quantities of a waste which would be
objectionable in a larger quantity may be accepted if sufficiently
diluted when and as discharged or if the quantity discharged is small
as compared to the flow in the receiving sewer; but any permission
to discharge minute quantities of an otherwise excluded waste shall
be revocable at any time by the town.
No wastewaters or substances which are excluded
from sanitary sewers shall be discharged into any storm sewer.
All measurements, tests and analyses of the
characteristics of waters and wastes to which reference is made in
this section shall be determined in accordance with Standard Methods
for the Examination of Water and Sewage. 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.
[Amended 2-14-1984; 9-10-1985]
Special agreements between the town and industry
allowing acceptance of industrial wastes of unusual strength or character
may be established, provided that:
A. Such wastes do not violate any pretreatment standards,
including national categorical pretreatment standards.
B. Said wastes do not cause interference with the operation
of the treatment plant, as defined in the General Pretreatment Regulations
of the United States Environmental Protection Agency, dated January
29, 1981.
C. Said wastes are subject to payment therefor by the
industrial concern.
