All users of the POTW will comply with all standards and requirements of the Act and standards and requirements promulgated pursuant to the Act.
A. 
No person shall discharge or cause to be discharged any stormwater, swimming pool water, surface water, roof runoff, subsurface drainage, uncontaminated cooling water or unpolluted industrial process waters to any sanitary or combined sewer, unless specifically authorized by the Superintendent. All stormwater, surface water, roof runoff, subsurface drainage, uncontaminated cooling water or unpolluted industrial process water shall be discharged to storm sewers or to any natural watercourse approved by the City Engineer. All existing connections to a sanitary or combined sewer of any stormwater, swimming pool water, surface water, roof runoff, subsurface drainage, uncontaminated cooling water or unpolluted industrial process waters shall be removed from the sewer within 60 days from the service of a written notice by the City to disconnect from the sewer.
B. 
If the owner of any property receiving a notice to disconnect from the sanitary or combined sewer does not disconnect within 60 days from the receipt of such notice, the City shall have the right and power and shall cause the same to be removed at the expense of the property owner and shall charge the total expense of such disconnection to the property so affected. The total expense incurred by the City to perform such work shall be paid by a special assessment upon the real estate so affected, which expense shall be a lien thereon, and which lien shall be superior and have priority to any mortgage, judgement or other lien of any nature affecting said premises. The City shall also have the power to collect, by a civil action brought in the name of the City, any expense it may incur for making such removal; but any civil action so brought shall not impair or affect the lien created under this chapter for such expense or be held to constitute a bar to any proceedings for the sale of lands under which said lien exists.
A. 
No person shall discharge directly or indirectly into the POTW, or into any private sewer emptying into the POTW, any substances, materials, waters or wastes in such quantities or concentrations which cause or are capable of causing, either alone or by interaction with other substances, interference with the operation or performance of the public sewer system or the wastewater treatment plant; or which pass through the wastewater treatment plant inadequately treated. These general prohibitions and the following specific prohibitions apply to all users of the POTW whether or not the user is subject to any other local, state or federal requirements governing use of the POTW.
B. 
No person shall discharge the following into the public sewer system:
(1) 
Pollutants which create a fire or explosion hazard in the POTW, including, but not limited to, waste streams with a closed-cup flashpoint of less than 140° F. (60° C.) using the test methods specified in 40 CFR 261.21.
(2) 
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 create a fire or explosion hazard in, or be injurious in any other way to, the public sewer system or the Norwich Wastewater Treatment Plant. At no time shall two successive readings on a flame-type 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, fuel oil, benzene, toluene, xylene, ethers, alcohols, carbides, hydrides, sulfides, and any other substances which the City Engineer, the DEC, or EPA has notified the users to constitute a fire or explosion hazard to the system.
(3) 
Solid or viscous substances which may cause obstruction to the flow in a sewer or otherwise interfere with the operation of the wastewater treatment facilities. Unless explicitly allowable by a written permit, such substances include, but are not limited to, grease, garbage with particles greater than 1/2 inch in any dimension, animal guts or tissues, paunch manure, bones, hair, hides or fleshings, entrails, whole blood, feathers, ashes, cinders, sand, spent lime, stone or marble dust, metal, glass, straw, shavings, grass clippings, rags, spent grains, spent hops, wastepaper, wood, plastics, gas, tar asphalt residues, residues from refining or processing fuel or lubricating oil, mud, or glass grinding or polishing wastes, and debris not normally contained in sanitary waste.
(4) 
Any wastewater having a pH less than 6.0 or greater than 9.0, or wastewater having any other corrosive property capable of causing damage or hazard to structures, equipment, and POTW personnel.
(5) 
Any wastewater containing toxic pollutants in sufficient quantity, either singly or by interaction with other pollutants (including heat), to injure or interfere with any wastewater treatment process, constitute a hazard to humans or animals, create a toxic effect in the receiving waters of the POTW, or to exceed the limitation set forth in a categorical pretreatment standard. A toxic pollutant shall include, but not be limited to, any pollutant identified pursuant to Section 307(a) of the Federal Act.
(6) 
Any noxious or malodorous solids, liquids, or gases which either singly or by interaction with other wastes are sufficient to create a public nuisance or a hazard to life or are sufficient to prevent entry into the sewers for their maintenance or repair.
(7) 
Oils and grease. Any commercial, institutional, or industrial wastes containing floatable fats, waxes, grease, or oils, or which become floatable when the wastes cool to the temperature prevailing in the wastewater at the POTW treatment plant during the winter season; also any commercial, institutional, or industrial wastes containing more than 100 mg/l of emulsified oil or grease; also any substances which will cause the sewage to become substantially more viscous at any seasonal sewage temperature in the POTW.
(8) 
Any substance which will cause interference or pass-through.
(9) 
Any wastewater with objectionable color which is not removed in the treatment process, such as, but not limited to, dye wastes, and vegetable tanning solutions.
(10) 
Any solid, liquid, vapor, or gas having a temperature, at the point of introduction into the City public sewer system, higher than 65° C. (150° F.), or in such quantities that cause the POTW treatment plant influent temperature to be greater than 40° C. (104° F.). The Superintendent reserves the right, in certain instances, to prohibit wastes at temperatures lower than 65° C.
(11) 
Any pollutants, including oxygen demanding pollutants (BOD, etc.), released at a flow rate and/or pollutant concentration which will cause interference with the treatment plant.
(12) 
Any wastewater containing any radioactive wastes.
(13) 
Any wastewater which causes a hazard to human life or which creates a public nuisance, either by itself or in combination, in any way, with other wastes.
No person shall discharge, directly or indirectly, into the POTW wastewater containing any of the following substances in concentrations exceeding those specified below on either a daily or an instantaneous basis. Concentration limits are applicable to wastewater effluents at the point just prior to discharge into the POTW (end of pipe concentrations).

A. 
Limitations on wastewater strength or mass discharge contained in this chapter may be supplemented with more stringent limitations when, in the opinion of the Superintendent:
(1) 
The limitations in this chapter are not sufficient to protect the POTW;
(2) 
The limitations in this chapter are not sufficient to enable the POTW treatment plant to comply with applicable water quality standards or the effluent limitations specified in the POTW's SPDES permit;
(3) 
The POTW sludge will be rendered unacceptable for disposal or reuse as the City desires, as a result of discharge of wastewaters at the above-prescribed concentration limitations;
(4) 
Municipal employees or the public will be endangered; or
(5) 
Air pollution and/or groundwater pollution will be caused.
B. 
The limitations on wastewater strength or mass discharge shall be recalculated at least once every five years. The results of these calculations shall be reported to the Superintendent. This chapter shall then be amended appropriately. Any issued industrial wastewater discharge permits which have limitations based directly on any limitations which were changed shall be revised and amended, as appropriate.
Except where expressly authorized to do so by an applicable pretreatment standard, no user shall ever increase the use of process water or, in any other way, attempt to dilute a discharge as a partial or complete substitute for adequate treatment to achieve compliance with a pretreatment standard. Dilution flow shall be considered to be inflow.
Grease, oil, and sand interceptors shall be provided when, in the opinion of the Superintendent, they are necessary for the proper handling of wastewater containing excessive amounts of grease, flammable substances, sand, or other harmful substances; except that such interceptors shall not be required for private living quarters or living units. All interceptors shall be of type and capacity approved by the City Engineer and shall be so located to be easily accessible for cleaning and inspection. Grease and oil interceptors shall be constructed of impervious materials capable of withstanding abrupt and extreme changes of temperature. They shall be of substantial construction, watertight, and equipped with removable covers which, when mounted in place, shall be gastight and watertight. Such interceptors shall be inspected, cleaned, and repaired regularly, as needed, by the owner at his expense.
No person shall discharge substances directly into a manhole or other opening in a public sewer other than through an approved building sewer.
Any person engaged in the hauling of septage wastes to the POTW must obtain a permit to do so. A hauler shall obtain a permit from the City of Norwich. In addition to Article X of this chapter, permitted haulers shall be responsible for complying with all the terms and conditions contained in the permit. Any person discharging to the POTW without a permit will be subject to the penalties provided for in Article XI of this chapter. All holding tank waste discharged to the POTW shall be discharged at the treatment facility at locations designated by the Superintendent. The discharge of hazardous wastes (as defined in Section 1004 of the Resource Conservation and Recovery Act) by septage haulers is prohibited. Each separate load of holding tank waste shall be registered with the operator of the treatment facility. The user shall pay the applicable charges or dumping fees and shall meet such other conditions as required by the City. The Superintendent shall have the right to inquire about the type of waste, the approximate volumes, and the origin of holding tank waste. The transporter of such wastes shall also have a waste transporting permit (6 NYCRR Part 364) issued by the DEC.
