No person shall discharge or cause to be discharged any stormwater, surface water, groundwater, roof runoff, subsurface drainage, uncontaminated 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 natural outlet approved by the designated officer of the town. Industrial cooling water or unpolluted process waters may be discharged, on approval of the officers of the town, to a storm sewer or natural outlet. Nothing herein is intended to overrule discharge standards imposed by the New York State Department of Environmental Conservation.
A. 
No person shall discharge or cause to be discharged any of the following-described waters or wastes to any public sewers:
(1) 
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.
(2) 
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° F.
(3) 
Any waters or wastes containing emulsified oil and grease exceeding an average of 50 parts per million [417 pounds per million gallons] ether soluble matter.
(4) 
Any liquids, solids 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 fire or explosion or be injurious in any other way to the POTW or to the operation of the POTW. At no time shall two successive readings on an explosion hazard meter at the point of discharge into the system (or at any point in the system) be more than 5% nor any single reading over 10% of the lower explosive limit (LEL) of the meter. Prohibited materials include but are not limited to gasoline, kerosene, naphtha, benzene, toluene, xylene, ethers, ketones, aldehydes, peroxides, chlorates, perchlorates, bromates, carbides, hydrides and sulfides and any other substances which the town, the state or EPA has notified the user is a fire hazard or a hazard to the system.
(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 of preventing entry into sewers for their maintenance and repair.
(6) 
Any garbage that has not been properly pulverized or ground to fine powder.
(7) 
Any ashes, cinders, sand, mud, straw, shavings, metal, glass, rags, feathers, tar, plastic, wood, paunch manure, hair and fleshings, entrails, lime slurry, lime residues, beer and distillery slops, 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 operations of the sewerage system.
(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 sewerage system. Free acids and alkalies must be neutralized, at all times, within a permissible pH range of 6.0 to 9.5.
(9) 
Any cyanides in excess of two parts per million by weight as CN.
(10) 
Any radioactive wastes or isotopes of such half-life or concentration as may exceed limits established by applicable local, state or federal regulations.
(11) 
Any waters or wastes that, for a duration of 15 minutes, have a concentration greater than five times the average of that of normal sanitary 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.
(12) 
Any stormwater, cistern or tank overflow, cellar drain, discharge from any vehicle wash rack or water motor or the contents of any privy vault, septic tank or cesspool or the discharge of effluent from any air-conditioning machine or refrigeration unit.
B. 
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 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 in volume and concentration by the Town Engineer. (Acceptance of such waste shall not cause the POTW to violate its SPDES permit or the receiving water quality standards or any pretreatment regulations promulgated by USEPA or NYSDEC in accordance with Section 307 of P.L. 95-217.)

Grease, oil and sand interceptors shall be provided when, in the opinion of the Town 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 Town Engineer and shall be located as to be readily and easily accessible for cleaning and inspection.
Grease and oil interceptors shall be constructed of impervious materials capable of withstanding abrupt and extreme changes in temperature. They shall be of substantial construction, watertight and equipped with easily removable covers which, when bolted in place, shall be gastight and watertight.
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 Engineer at any time.
The admission into the public sewers of any waters or wastes having a five-day biochemical oxygen demand greater than 300 parts per million by weight or containing more than 350 parts per million by weight of suspended solids or containing more than 15 parts per million of chlorine demand or containing any quantity of substances having the characteristics above the previously described limits 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 Town Engineer. Where necessary, in the opinion of the Town Engineer, the owner shall provide, at his expense, such preliminary treatment as may be necessary to reduce the biochemical oxygen demand to 300 parts per million and the suspended solids to 350 parts per million by weight or reduce the chlorine demand to 15 parts per million or reduce objectionable characteristics or constituents to within the maximum limits provided for 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 Town Engineer and none of the appropriate facilities shall be commenced until said approvals are obtained in writing.
Where preliminary treatment 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 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 shall be determined in accordance with Standard Methods of Examination of Water and Sewage and upon suitable samples taken at the control manhole provided for above. In the event that no special manhole has been required, the control manhole is the public town sewer nearest to the point at which the building sewer is connected.
