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 Town. Industrial cooling water or unpolluted
process waters may be discharged, upon approval of the Town, to a
storm sewer or natural outlet.
Except as hereinafter provided, no person shall discharge or
cause to be discharged any of the following described waters or wastes
to any public sanitary sewer:
A. Any liquid or vapor having a temperature higher than 150° F.
(65° C.) or that would cause the temperature of the treatment
plant influent to exceed 104° F. (40° C.).
B. Any waters or wastes which contain grease or oil or other substance
that will solidify or become discernibly viscous at temperatures between
32° F. and 150° F.
C. Any waters or wastes containing fats, wax, grease or oils, whether
emulsified or not, exceeding an average of 50 parts per million (417
pounds per million gallons) ether-soluble matter.
D. Any solids, liquids or gases which, by reason of their nature or
quantity, are or may be sufficient, either alone or by interaction
with other substances, to cause a fire or an explosion or be injurious,
in any way, to the sewage treatment plant or to the operation of the
sewage treatment plant. At no time shall both of two successive readings
on a flame-type explosion hazard meter, at the point of discharge
into the system (or at any other point in the system), be more than
25% nor any single reading be more than 40% of the lower explosive
limit (LEL) of the meter. Unless explicitly allowable by a written
permit, prohibited materials include, but are not limited to, gasoline,
kerosene, naphtha, benzene, toluene, xylene, ethers, alcohols, carbides,
hydrides and sulfides, and any other substance which the Town, the
state or the EPA has determined to be a fire hazard or hazard to the
sewage treatment plant.
E. 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 of preventing entry into sewers for their maintenance and
repair.
F. Any pollutants which result in the presence of toxic gases, vapors
or fumes within the sewage treatment plant in a quantity that may
cause acute worker health and safety problems.
G. 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 Town.
H. 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 system.
I. 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 system. Free acids and alkalies must be
neutralized at all times within a permissible pH range of 6.0 to 9.5.
J. Any cyanides in excess of two parts per million by weight as CN.
K. Any radioactive wastes or isotopes of such half-life or concentration
as may exceed limits established by the Town in compliance with applicable
state or federal regulations.
L. 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 are discharged continuously at a rate
exceeding 1,000 gallons per minute, except by special permit. "Normal"
sanitary sewage shall be construed to fall within the following ranges
at the effluent of the industrial plant in question:

M. Any stormwater, roof drains, spring water, cistern or tank overflow,
footing drain or the contents of any privy vault, septic tank or cesspool
or the discharge or effluent from any air-conditioning machine or
refrigeration unit.
N. No person shall discharge or cause to be discharged any waters or
wastes containing 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 toxic effect in the receiving waters or cause
the effluent of the Village sewer treatment plant to exceed SPDES
discharge limits or pretreatment standards. Such toxic substances
shall be limited to the average concentrations listed hereinafter
in the sewage at its point of entry to the public sewers, and at no
time shall the maximum instantaneous concentration entering the public
sewers exceed three times the average concentration. If concentrations
listed are exceeded, individual establishments will be subject to
control by the Town Engineer in volume and concentration of wastes
discharged.

Exceptions to these limits may be considered and allowed within the requirements contained in Article XXII, Industrial Wastewater Discharge Permits, of this Part 3.
|
O. Any food-canning wastes except after pretreatment approved by the
Town Board or Town Engineer and conducted by the owner to remove all
bulk solids and particles greater than one-eighth-inch size in any
dimension.
P. Any wastewater with objectionable color which is not removed in the
treatment process, such as, but not limited to, dye wastes and vegetable
tanning solutions.
Q. Unusual flow rate or concentration of wastes, constituting slugs,
except by Industrial Wastewater Permit.
R. Any wastewater which causes a hazard to human life or which creates
a public nuisance, either by itself or in combination, in any way,
with other wastes.
S. Any wastewater with a closed cup flashpoint of less than 140°
F. or 60° C. using the test methods specified in 40 CFR Part 261.21.
Where installed, all grease, oil and sand interceptors shall
be maintained by the owner at his expense in continuously efficient
operation at all times and shall be readily accessible and open to
inspection by the Town at any time.
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 Town Engineer, the owner of any property
served by a building sewer carrying industrial wastes shall install
a suitable control manhole 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 Town Engineer. The manhole shall
be installed by the owner at his expense and shall be maintained by
the owner 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 §
102-109 and §
102-112 shall be determined in accordance with Standard Methods for the Examination of Water and Wastewater upon suitable samples taken at the control manhole provided for in §
102-114. 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.
All industrial establishments contributing or intending to contribute
industrial wastes to the public sewers shall comply with the following
provisions:
A. Users of the Town sewers and wastewater treatment plant shall comply
with the General Pretreatment Regulations (40 CFR 403) and any amendments
thereto.
B. Disposal into the public sewers of any pollutant by any person is
unlawful except in compliance with federal standards promulgated pursuant
to the FWPCA.
C. Permission shall be granted to authorized employees of the EPA and
the New York State Department of Environmental Conservation (NYSDEC)
to enter properties of contributing industries for the purpose of
inspection, observation, measurement, sampling and testing.
D. All industrial establishments, as a prerequisite for authorization
for disposal into the public sewer, must provide information to the
Town describing wastewater constituents and characteristics and the
type of industrial activity involved.
E. Major contributing industries and other contributing industries,
as deemed necessary, shall file periodic reports with the Town on
the constituents and characteristics of their wastewaters. Frequency
of reporting and information to be contained in such reports shall
be determined by the Town.
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 wastes 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.
