No person shall discharge or cause to be discharged any stormwater, surface water, groundwater, roof run-off or subsurface drainage to any public sanitary sewer.
Stormwater, groundwater and all other unpolluted drainage shall be discharged to such sewers as are specifically designated as storm sewers or drainage ditches. Discharge of cooling water or process water to a natural outlet shall require a permit in accordance with the National Pollution Discharge Elimination System as administered by the NYSDEC.
No person shall discharge or cause to be discharged any of the following described liquids, waters, or wastes to any public sanitary sewer:

(5) 
Any water or as satisfactory in terms of capacity and yield; bacteriological testing results are acceptable;
(6) 
Any water or wastes containing emulsified oil or grease exceeding 75 mg/l of ether-soluble matter;
(7) 
Any wastes that contain concentrated dye wastes or other wastes that are either highly colored or become highly colored upon reacting with other wastes;
(8) 
Any wastes containing a toxic substance in sufficient quantity to:
(a) 
Constitute a health hazard to humans;
(b) 
Cause damage to any ecosystem to which the waste may come in contact;
(c) 
Cause damage to or create a hazardous condition in any component of the treatment works.
B. 
The following substances shall be considered as toxic and their discharge shall be limited to the concentrations shown in the table below:

[Amended 9-12-1984]
The discharge to the public sanitary sewer of toxic substances shall be allowed to exceed the requirements as stated in § 196-5.4A(8) only with the written approval of the NYSDEC. Any proposed discharge of toxic materials shall be requested by letter to the Sewer District and shall be accompanied by a facilities report stating the conditions of the proposed discharge. The facilities report shall thereby establish limits for the approved discharge only, which shall not be exceeded. No special agreement shall circumvent federal pretreatment standards and requirements.
All industrial discharges to the public sanitary sewers shall be in accordance with pretreatment regulations that have been or may be promulgated by the U.S. Environmental Protection Agency as required by Section 307 of P.L. 92-500, if more stringent than the requirements of § 196-5.4 of this chapter.
Discharge of any substance described in § 196-5.3 or § 196-5.4 or the discharge of any substance in excess of the limits established in § 196-5.4A(8) shall constitute a violation of the provisions of this chapter.
Grease, oil or grit traps shall be provided when, in the opinion of the Superintendent, they are necessary for the handling of liquids containing greases or any flammable wastes or grits; except that such traps shall not be required for a single-family detached dwelling unit. All traps shall be of a type and capacity approved by the Superintendent and shall be located to be readily and easily accessible for cleaning and inspection. Grease and oil traps 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 secured in place, shall be gastight and watertight.
Where installed, all grease, oil and grit traps shall be maintained by the owner, at his
The admission into the public sanitary sewers of any waters or wastes at the point of discharge into the sewer, containing (a) BOD greater than 300 mg/l, or (b) more than 300 mg/l of suspended solids, or (c) any quantity of substances having a peak flow greater than 2% of the average daily sewage flow of the Sewer District shall be subject to review and approval of the Sewer District.
Where necessary in the opinion of the Sewer District, the owner shall provide, at his expense, such pretreatment as may be necessary to reduce the BOD and/or suspended solids to 300 mg/l, or to reduce objectionable characteristics or constituents to within the maximum limits provided for in § 196-5.3 and § 196-5.4 or control the quantities and rates of discharge of such waters or wastes.
Plans, specifications and other pertinent information relating to the proposed pretreatment facilities shall be prepared and submitted by a professional engineer, licensed in the State of New York, for approval of the Sewer District, and no construction of such facilities shall be commenced until said approvals are obtained in writing.
Where the concentrations of sewage from an industrial, commercial or institutional establishment exceeds: (a) 300 mg/l of BOD, or (b) 300 mg/l of suspended solids, or (c) the total phosphorous measured as P is greater than 10 mg/l and where such wastes are permitted to be discharged to the sewer system by the Sewer District, an added charge shall be made against such establishments according to the concentration of such wastes. The loading of such wastes shall be determined by composite samples taken over the period of time to develop a representative sample and by low data collected over a period of time to develop a representative probability plot. The collection and analyses of samples and flow data shall be conducted by the Sewer District or an authorized representative.
[Added 9-12-1984]
Where pretreatment facilities are provided for any waters or wastes, they should be operated and maintained continuously by the owner at his expense.
The Sewer District may require the owner of any property served by a building sewer carrying industrial wastes to install a wastewater flow meter and sampling device in a suitable control manhole in the building sewer to facilitate observation, sampling and measurement of the wastes. Such a manhole shall be located, constructed and maintained in accordance with plans approved by the Sewer District at the owner's expense.
All measurements, tests and analyses of the characteristics of waters and wastes to which reference is made in § 196-5.3, § 196-5.4, § 196-5.10 and § 196-5.11 shall be determined in accordance with "Laboratory Determinations" as defined in § 196-1.2 and shall be determined at the control manhole provided for in § 196-5.15, or upon suitable samples taken at said control manhole. In the event that no special manhole has been constructed, 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.
To determine the sewage flow from any establishment, the Sewer District may use one of the following methods in the following subsections:
A. 
The amount of water supplied to the premises by the Town or a private water company as shown upon the water meter if the premises are metered.
B. 
If the premises are supplied with river water or water from private wells, the amount of water supplied from such sources as estimated by the Town from the water, gas or electric supply.
C. 
The number of gallons of sewage discharge into the sewer system as determined by measurements taken with a wastewater flow meter as described in § 196-5.15.
D. 
A figure determined by the Town by any combination of the foregoing or by any other equitable method.
No industrial wastewater shall be discharged to a trunk sewer or a sewer discharging directly or indirectly to a trunk sewer until a permit for industrial wastewater discharge has been approved by the Superintendent.
No statement contained in Article V shall be construed as preventing any special agreement or arrangement between the Sewer District and any industrial user whereby industrial wastes may be accepted by the Sewer District subject to payment therefor by the industrial user. No special agreement shall circumvent federal pretreatment standards and requirements.
