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 Board. Industrial cooling water or unpolluted process waters may be discharged, upon approval of the Board, the NYSDEC and the USEPA 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.) or in such quantities that the temperature at the treatment works influent exceeds 104° F. (40° C.) unless the works are designed to accommodate such heat.
B. 
Any waters or wastes which contain grease or oil or other substance that will solidify or become discernibly viscous at temperatures between 32° and 150°.
C. 
Any waters or wastes containing fats, wax, grease or oils, whether emulsified or not, exceeding an average of 100 milligrams per liter, 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, 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 Board.
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 permissable pH range of 5.5 to 9.5.
I. 
Any cyanides, in excess of 0.2 milligrams per liter by weight as CN.
J. 
Any radioactive wastes or isotopes of such half-life or concentration as may exceed limits established by the Board in compliance with state or 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 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:
Constituents
Permissible Range
(mg/l)
Suspended solids
180 to 350
BOD
140 to 300
Chlorine requirements
5 to 20
L. 
Any stormwater, roof drains, springwater, cistern or tank overflow, footing drain, discharge from any 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. 
Limitations on toxic substances.
(1) 
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 any sewage treatment facility to which the town's sewage collection system is tributary. 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 Board in volume and concentration of wastes discharged.

(3) 
The above limits shall be superseded when new limits are established by the NYSDEC or USEPA.
A. 
Grease, oil and sand interceptors shall be provided when the above-set limits for those substances are exceeded or when, in the opinion of the Engineer, 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 interceptors shall not be required for private living quarters or dwelling units. All interceptors shall be of a type and capacity approved by the Engineer, and shall be located as to be readily and easily accessible for cleaning and inspection.
B. 
Grease and oil interceptors 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 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 Board 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 by weight, or containing more than 350 milligrams per liter of suspended solids, or containing more than 20 milligrams per liter of chlorine demand, or containing any quantity of substances having the characteristics described in § 70-34 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 to 20 milligrams per liter or reduce objectionable characteristics or constituents to within the maximum limits provided for in § 70-34 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 Department of Environmental Conservation 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 Part 1.
When required by the Board, 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 §§ 70-34 and 70-36 shall be determined in accordance with the Standard Methods for the Examination of Water and Sewage, or National Pretreatment Standards developed by EPA, 40 CFR 403 including all amendments upon suitable samples taken at control manhole provided for in § 70-39. 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.
A. 
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.
B. 
The laboratory methods used in the examination of all industrial wastes shall be those set forth in the latest edition of the Standard Methods for the Examination of Water and Sewage, published by the American Public Health Association. However, alternative methods for the analysis of industrial wastes may be used subject to mutual agreement between the Board and the producer of such wastes.
C. 
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 Board.
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.
