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 enforcement officer.
Industrial cooling water or unpolluted process waters may be discharged,
upon approval of the enforcement officer, to a storm sewer or watercourse.
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 water or wastes which contain grease or oil or
other substances 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) 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 repairs.
F. Any garbage that has not been properly shredded. The
installation and operation of any garbage grinder equipped with a
motor of 1/4 horsepower or greater shall be subject to the review
and approval of the Director of Utilities.
G. 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 viscous substance capable of causing
obstruction to the flow of the sewers or other interference with the
proper operation of the sewerage system.
H. Any waters or wastes, acid or 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 6.5 to 9.5.
I. Any cyanides, in excess of 0.1 part per million by
weight as CN.
J. Any radioactive wastes or isotopes of such half-life
or concentration as may exceed limits established by the Director
of Utilities in compliance with the applicable state and federal regulations.
K. 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:

L. Any stormwater, roof drains, springwater, cistern
or tank overflow, footing drain or the contents of any privy vault,
septic tank or cesspool or the discharge of effluent from any air-conditioning
machine or refrigeration unit.
M. Any waters or wastes containing a toxic or poisonous
substance, a high chlorine demand, a high BOD 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 water or the effluent of the Town water pollution
control plant. Such toxic substances shall be limited to the average
concentrations listed hereinafter in the sewage as it arrives at the
plant, and at no time shall the hourly concentration at the plant
exceed three times the average concentration. If concentrations listed
are exceeded, individual establishments will be subject to control
in volume and concentration of sewage by the Director of Utilities
and the Town Board. The concentrations of toxic substances are to
be limited at the point of entry into the municipal collection system.

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 Director of Utilities 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 Director of Utilities,
the owner of any property served by a building lateral carrying industrial
wastes shall install a suitable control manhole in the building 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
Director of Utilities. 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 §§
95-31 and
95-34 shall be determined in accordance with Standard Methods for the Examination of Water and Wastewater from suitable samples taken at the control manhole provided for in §
95-36. 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 from the point at which the building lateral is connected.
No statement contained in this article 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 sewage
works, 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 a quarter, for 24 hours. However, more
frequent and longer periods may be required at the discretion of the
Town Board.
All of the preceding rules, regulations and
standards are also subject to any pretreatment standards established
pursuant to Section 307 of Public Law 92-500 in accordance with the
requirements of the National Pollutant Discharge Elimination System
permit.
