No person shall discharge or cause to be discharged
any stormwater, surface water, groundwater, swimming pool water, roof
runoff, subsurface drainage, 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 storm sewers or to a watercourse approved by the Superintendent.
Industrial cooling water or unpolluted process waters may be discharged,
upon approval of the Superintendent, to a storm sewer or natural outlet.
A.
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:
(1)
Any liquid or vapor having a temperature higher than
150º F. (65º C.).
(2)
Any waters or wastes which contain grease or oil or
other substance that will solidify or become discernibly viscous at
temperatures between 32º F. and 150º F.
(3)
Any waters or wastes containing either soluble fats,
wax, grease or oils, whether emulsified or not, exceeding an average
of 50 milligrams per liter (417 pounds per million gallons).
(4)
Any gasoline, benzine, naphtha, fuel oil or mineral
oil or other flammable or explosive liquid, solid or gas.
(5)
Any noxious or malodorous gas, such as hydrogen sulfide,
sulfur dioxide or nitrous oxide or other substance, which, either
singly or by interaction with other wastes, is capable of creating
a public nuisance or hazard to life or preventing entry into sewers
for their maintenance and repair.
(6)
Any garbage that has not been properly shredded. 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.
(7)
Any ashes, cinders, sand, mud, straw, shavings, metal,
glass, rags, feathers, tar, plastic, cardboard, wood, paunch manure,
hair and fleshings, entrails, lime slurry, lime residues, beer or
distillery slops, whey, chemical residues, paint residues, cannery
waste, bulk solids or any other solid or viscous substance capable
of causing obstruction to the flow of the sewers or other interference
with the proper operation of the sewage works.
(8)
Any waters or wastes, acid and alkaline in reaction,
having corrosive properties capable of causing damage or hazard to
structures, equipment and personnel of the sewage works. Free acids
and alkalis must be neutralized at all times, within a permissible
ph range of 6.0 to 9.5.
(9)
Any cyanides in excess of two milligrams per liter
as CN.
(10)
Any radioactive wastes or isotopes of such half-life
or concentration as may exceed limits established by the Engineer
in compliance with applicable state or federal regulations.
(11)
Any waters or wastes that, for a duration of
15 minutes, have a concentration greater than five times that of normal
sewage as measured by suspended solids and BOD and/or which is discharged
continuously at a rate exceeding 1,000 gallons per minute except by
special permit. Normal sewage shall be construed to fall within the
following ranges:

or the contents of any privy vault, septic tank or cesspool or the
discharge or effluent from any air conditioning machine or refrigeration
unit.
B.
No person shall discharge or cause to be discharged
any waters or wastes containing high BOD, a toxic or poisonous substance,
a high chlorine demand or suspended solids in sufficient quantity
to injure or interfere with any sewage treatment process, constitute
a hazard to humans or animals or create any hazard in the receiving
waters or the effluent of the wastewater treatment facilities. Such
toxic substances shall be limited to the average concentrations listed
hereinafter in the sewage as it arrives at the treatment plant and,
at no time shall the hourly concentration at the sewage treatment
plant exceed three times the average concentration. If concentrations
listed are exceeded, individual establishments will be subject to
control by the Engineer or Superintendent in volume and concentration
of wastes discharged.

A.
Grease, oil and sand traps shall be provided when
the above limits for those substances are exceeded or when, in the
opinion of the Engineer or Superintendent, they are necessary for
the proper handling of liquid wastes containing grease in excessive
amounts or any flammable wastes, sand and other harmful ingredients,
except that such traps shall not be required for private living quarters
or dwelling units. All traps shall be of a type and capacity approved
by the Engineer or Superintendent and shall be located as to be readily
and easily accessible for cleaning and inspection.
B.
Grease and oil traps shall be constructed of impervious
materials capable of withstanding abrupt and extreme changes in temperatures.
They shall be of substantial construction, watertight and equipped
with easily removable covers which, when bolted in place, shall be
gastight and watertight.
C.
Where installed, all grease, oil and sand traps shall
be maintained by the owner, at his or her expense, in continuously
efficient operation at all times and shall be readily accessible and
open to inspection by the Superintendent of Sewers at any time.
A.
Excessive BOD. The admission into the public sewers
of any waters or wastes having the following characteristics shall
be subject to the review and approval of the Engineer:
Amended 9-14-2021 by L.L. No. 2-2021]
B.
Pretreatment. Where necessary, in the opinion of the
Engineer or Superintendent, the owner shall provide, at his or her
expense, such pretreatment as may be necessary to:
(1)
Reduce the Biochemical Oxygen Demand to 200 mg/l;
[Amended 9-14-2021 by L.L. No. 2-2021]
(2)
Reduce the chlorine requirements to 15 mg/l;
(3)
Reduce objectionable characteristics or constituents to within the maximum limits provided for in § 118-32; or
(4)
Control the quantities and rates of discharge of such
waters or wastes.
C.
Plans and specifications to be approved. Plans, specifications
and any other pertinent information relating to proposed pretreatment
facilities shall be submitted for approval of the Engineer and of
the Health Department of the State of New York, and no construction
of such facilities shall be commenced until said approvals are obtained
in writing. Failure to comply with one or more of the remedial procedures
as required by the Engineer will constitute a violation of this chapter.
Where pretreatment 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 or her
expense.
When required by the Engineer, the owner of
any property served by a building sewer lateral carrying industrial
wastes shall install a suitable control manhole in the building sewer
lateral 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 Town Engineer. The manhole shall be installed by the owner
at his or her expense and shall be maintained by him or her 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 §§ 118-32 and 118-36 shall be determined in accordance with Standard Methods for the Examination of Water and Wastewater. 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.
No statement contained in this chapter shall
be construed as preventing any special agreement or arrangement between
the town and any industrial concern whereby an industrial waste of
unusual strength or character may be accepted by the town for treatment,
subject to payment therefor by the industrial concern.
All of the preceding standards are to apply
at the point where the industrial wastes are discharged into the public
sanitary sewerage system and any chemical or mechanical corrective
treatment required must be accomplished to practical completion before
the wastes reach that point. The laboratory methods used in the examination
of all industrial wastes shall be those set forth in the latest edition
of Standard Methods for the Examination of Water and Wastewater, published
by the American Public Health Association. However, alternate methods
for the analysis of industrial waste may be used, subject to mutual
agreement between the Town Board and the producer of such wastes.
The frequency and duration of the sampling of any industrial waste
shall not be less than once every three months for a twenty-four-hour
period. However, more frequent and longer periods may be required
at the discretion of the Town Board.
