No person shall discharge or cause to be discharged any stormwater,
surface water, groundwater, 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 Inspector. Industrial cooling water
or unpolluted process waters may be discharged, upon approval of the
Inspector, 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 sewer:
A. Any liquid or vapor having a temperature higher than 150° F.
(65° 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 milligrams/liter (417
pounds per million gallons) or other soluble matter.
D. Any gasoline, benzine, naphtha, fuel oil or mineral oil or other
flammable or explosive liquid, solid or gas.
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 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 Inspector.
G. Any ashes, cinder, 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.
H. 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 alkalies must be
neutralized, at all times, within a permissible pH range of 6.0 to
9.5.
I. Any cyanides in excess of 0.3 milligrams per liter by weight as CN.
J. Radioactive wastes that do not comply with federal or state regulations.
K. Any water or waste that for a duration of 15 minutes has 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
300 gallons per minute except by special permit. "Normal sewage" shall
be defined as falling within the following ranges:

Suspended solids
|
180 to 350
|

L. Any stormwater, roof drains, spring water, cistern or tank overflow,
footing drain, discharge form any vehicle wash rack or water motor
or the contents of any privy vault, septic tank or cesspool or the
discharge or effluent from any air-conditioning machine or refrigeration
unit.
M. 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 hazard in the receiving waters or the effluent
of the Town sewage treatment plant. Such toxic substances shall be
limited to the average concentrations listed hereinafter in the sewage
at the point where it is discharged in the public sanitary sewage
system, and at no time shall the hourly concentration exceed three
times the average concentration. If concentrations listed are exceeded,
individual establishments will be subject to control by the Engineer
in volume and concentration of wastes discharged.

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 Inspector at any time.
The admission into the public sewers of any waters or wastes having a five-day biochemical oxygen demand greater than 300 milligrams per liter or containing more than 350 milligrams per liter of suspended solids or containing more than 15 milligrams per liter of chlorine requirement or containing any quantity of substances having the characteristics described in §
102-35 or having an average daily flow greater than 2% of the average daily sewage flow of the Town shall be subject to the review and approval of the Engineer. Where necessary, in the opinion of the Engineer, the owner shall provide, at his expense, such preliminary treatment as may be necessary to reduce the biochemical oxygen demand to 300 milligrams per liter and the suspended solids to 350 milligrams per liter by weight or reduce the chlorine requirements to 15 milligrams per liter or reduce objectionable characteristics or constituents to within the maximum limits provided for in §
102-36 or control the quantities and rates of discharge of such waters or wastes. Plans, specifications and any other pertinent information relating to proposed preliminary treatment facilities shall be submitted for the approval of the Engineer and of the New York State Department of Environmental Conservation, and no construction of such facilities shall be commenced until said approvals are obtained in writing. When pretreatment standards are adopted by the United States Environmental Protection Agency and the New York State Department of Environmental Conservation for any given class of industries, then such industries must immediately conform to the timetable for adherence to these standards. Failure to comply with one or more of the remedial procedures as required by the Engineer will constitute a violation of this Part
1.
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 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 Engineer. 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 §§
102-36 and
102-40 shall be determined in accordance with the most recent edition of Standard Methods for the Examination of Water and Wastewater upon suitable samples taken at the control manhole provided for in §
102-41. 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 Part 1 shall be construed as
preventing any special agreement or arrangement between the Town or
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 wastes may be used, subject to mutual
agreement between the Town Board and the producer of such wastes,
subject to the approval by the NYSDEC. 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.
