All users of the Town of Webster's POTW will comply with all standards and requirements of the Act and standards and requirements promulgated pursuant to the Act, including but not limited to 40 CFR Parts 401-471, and/or any other federal and/or state or local standard for water pollution control which is more stringent.
A. 
General prohibitions. No user shall contribute or cause to be contributed, in any manner or fashion, directly or indirectly, any pollutant or wastewater which will cause pass-through or interference or contaminate the ground and/or groundwater by leaking out of the sewer. These general prohibitions apply to all such users of a POTW whether or not the user is subject to National Categorical Pretreatment Standards or any other national, state, or local pretreatment standards or requirements. Pollutants or wastewater prohibited by this section shall not be processed or stored in such a manner that they could be discharged to the POTW.
B. 
Specific prohibitions. Without limiting the generality of the foregoing, a user may not contribute the following substances to the POTW:
(1) 
Any solids, liquids, 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 a fire or an explosion or be injurious, in any way, to the POTW or to the operation of the POTW or inhibit biological activity resulting in interference [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 other point in the system, be more than 25%, nor any single reading be more than 40%, of the lower explosive limit (LEL) of the meter], and pollutants, including but not limited to waste streams with a closed-cup flash point of less than 140° F. (60° C.) using the test methods specified in 40 CFR 261.21. Unless explicitly allowable by a written permit by the Chief Plant Operator and/or Superintendent of Sewers, prohibited materials include but are not limited to gasoline, kerosene, naphtha, benzene, toluene, xylene, ethers, alcohols, keytones, aldehydes, peroxides, chlorates, perchlorates, perchloroethylene, bromates, carbides, hydrides, and sulfides, and any other substance which the Town of Webster, the County of Monroe, the state, or the EPA has determined to be a fire hazard or a hazard to the POTW.
(2) 
Any wastewater having a pH less than 5.5 or greater than 10.0, or wastewater having any other corrosive property capable of causing damage or hazard to structures, equipment, and/or POTW personnel. Prohibited materials include but are not limited to acids, sulfides, concentrated chloride, fluoride compounds, and substances which react with water to form acid or basic products.
(3) 
Solid or viscous pollutants in amounts which will cause obstruction to the flow in a sewer or otherwise interfere with the operation of the wastewater treatment facilities. Such substances include but are not limited to grease, garbage with particles greater than 1/2 inch in any dimension, animal guts or tissue, paunch manure, bones, hair, hides or fleshings, entrails, whole blood, fetus, products of abortion, surgical specimens, feathers, ashes, creosols, creosotes, 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 glass-polishing wastes.
(4) 
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 Act.
(5) 
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 to prevent entry into the sewers for their maintenance or repair.
(6) 
Any pollutants which result in the presence of toxic gases, vapors, or fumes within the POTW or appearances in a quantity that may cause acute worker health and safety problems.
(7) 
Petroleum oil, nonbiodegradable cutting oil, or products of mineral oil origin, in amounts greater than 100 mg/l or in amounts that will cause interference or pass-through.
(8) 
Fats, oils and grease: any commercial, institutional, or industrial wastes containing fats, waxes, grease, or oils, or which become visible solids when the wastes cool to the temperature prevailing in the wastewater in the collection system or 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 of animal or vegetable origin; also any substances which will cause the sewage to become substantially more viscous, at any seasonal sewage temperature in the POTW.
(9) 
Any substance, including oxygen-demanding pollutants (BOD, COD, etc.) or chlorine, bromine, iodine, or fluorine released in a discharge at a flow rate and/or pollutant concentration which, either singly or by interaction with other pollutants, will cause interference with or pass through the POTW, or will cause a significant additional load on the sewage treatment works.
(10) 
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.
(11) 
Unusual flow rate or concentration of wastes constituting slugs, as defined herein, except by industrial wastewater permit.
(12) 
Any institution or industry discharging radioactive material or fission products must be registered with the Town of Webster Sewer Department as well as with other regulatory agencies as the law requires. The registration shall include all copies of state and federal permits governing the waste discharge. The active elements and the local concentrations permitted to be discharged into the public sewers shall be in conformance with State Sanitary Code Chapter I, Part 16, Sections 16.7 and 16.8, of the Public Health Law, 6 NYCRR Part 380: Rules and Regulations for the Prevention and Control of Environmental Pollution by Radioactive Materials, and at all times shall be within the limits set by this and other county, state, or federal agencies.
(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.
(14) 
Any substance which may cause the POTW's effluent or any other product of the POTW, such as residues, sludges, or scums, to be unsuitable for reclamation and reuse or to interfere with the reclamation process. In no case shall a substance be discharged to the POTW which would cause the POTW to be in noncompliance with the sludge use or disposal criteria, guidelines or regulations developed under Section 405 of the Act or any criteria, guidelines or regulations affecting sludge use or disposal developed pursuant to the Solid Waste Disposal Act, the Clean Air Act, the Toxic Substances Control Act or local criteria applicable to the sludge management method being used.

A. 
The categorical pretreatment standards found in 40 CFR Chapter I, Subchapter N, Parts 405-471, are hereby incorporated.
(1) 
Where a categorical pretreatment standard is expressed only in terms of either the mass or the concentration of a pollutant in wastewater, the Chief Plant Operator and/or Superintendent of Sewers may impose equivalent concentration or mass limits in accordance with 40 CFR 403.6(c)(1)-(2).
(2) 
When wastewater subject to a categorical pretreatment standard is mixed with wastewater not regulated by the same standard prior to treatment, the Chief Plant Operator and/or Superintendent of Sewers may impose an alternate limit using the combined waste stream formula in 40 CFR 403.6(e).
(3) 
A user may obtain a variance from EPA Region 2 from a categorical pretreatment standard if the user can prove, pursuant to the procedural and substantive provisions in 40 CFR 403.13, that factors relating to its discharge are fundamentally different from the factors considered by EPA when developing the categorical pretreatment standard.
(4) 
A user may obtain a net gross adjustment to a categorical standard in accordance with 40 CFR 403.15.
B. 
Upon the promulgation of new or revised federal categorical pretreatment standards for a particular industrial subcategory, the federal standard, if more stringent than limitations imposed under this Sewer Use Law for sources in that subcategory shall immediately supersede the limitation imposed under this Sewer Use Law.
No person shall discharge, directly or indirectly, into the POTW, any discharge which would exceed the permit standard wastewater containing any of the following substances in concentrations exceeding those specified below on either a daily or an instantaneous basis, except by permit or as provided for in § 257-74. Concentration limits are applicable to wastewater effluents at the point just prior to discharge into the POTW ("end of pipe" concentrations).
A. 
Permissible concentration of toxic substances.
(1) 
With the exception of sewer users covered by the federal categorical pretreatment standards, the concentration in sewage of any of the following toxic substances shall not exceed the twenty-four-hour average or thirty-day average concentration limits specified below when discharged into the public sewer.
(2) 
Sewer users covered by the federal categorical pretreatment standards shall comply with applicable federal standards. For these users, substances not regulated by the categorical pretreatment standards shall not exceed the concentration limits specified below. For substances regulated by the categorical pretreatment standards, determination of concentration shall be at the discharge into the sewer with the dilution attributed to nonprocess flow excluded as determined by the combined waste stream formula (40 CFR 403.6).
(3) 
The Town of Webster may revise with its rules and regulations the following limits or insert additional items after hearing when, in the opinion of the Chief Plant Operator and/or Superintendent of Sewers or County Department of Health, the need for a rule change is indicated, or as provided in the federal categorical pretreatment standards.
(4) 
The following list contains the permitted toxic substances and levels of concentration.

(5) 
Special concentration limits. When findings of the Town of Webster show that the volume of a single toxic industrial waste discharge or a combined toxic industrial waste discharge of a group of industries within a single contributory area is so large as to raise a question of the ultimate concentration of toxic substances entering the POTW, or in cases where it is known that the toxic substances in the concentrations involved will be effectively removed by the POTW without causing deleterious effects of any kind to the treatment process, the treatment plant, sludge, or the receiving waters after treatment, the Town of Webster may rule that separate or special concentration limits shall be used by the contributors in that area. Concentration limits at variance with the federal categorical pretreatment standards will not be granted.
B. 
In addition to the above-mentioned limits, the maximum allowable industrial loadings that the Town POTW and the Village POTW Headwork's can handle are listed in the following tables, and these local limits shall be implemented through sewer use permits.

(2) 
As determined on a composite sample taken from the user's daily discharge over a typical operational and/or production day, except for cyanide, phenol, pH, oil and grease, which shall be determined using grab samples.
C. 
The limits for organic pollutants other than those listed in this section and higher than the minimum detection limits as established by 40 CFR Part 136 and/or the current edition of Standard Methods shall be set on a case-by-case basis. These limits shall be determined by the Chief Plant Operator and/or Superintendent of Sewers using screening level criteria, process biological treatability, safety criteria, receiving water quality criteria, sludge disposal options, New York State Department of Environmental Conservation's "Operational Guidance Manuals" and USEPA guidelines, etc.
D. 
Other substances which may be limited are: antibiotics; asbestos; chemical compounds which, upon acidification, alkalinization, oxidation or reduction in the discharge or after admixture with wastewater and its components in the POTW, produce toxic, flammable, or explosive compounds; pesticides, including algicides, fungicides, herbicides, insecticides, and rodenticides; polyaromatic hydrocarbons; and viable pathogenic organisms from industrial processes or hospital procedures.
A. 
The Chief Plant Operator and/or Superintendent of Sewers may impose mass-discharge-based limits on individual users for specific pollutants based upon a wastewater treatability analysis. Mass-discharge-based limits may be imposed for pollutants which may have negative impact on the POTW, POTW employees or the receiving water. The Chief Plant Operator and/or Superintendent of Sewers shall issue permits to significant industrial users and may issue permits to other industrial/commercial users limiting the discharge of these substances. Each permit shall restrict the discharge from each significant industrial user to a portion of the total allowable influent loading. In determining what portion of the total of each substance that each significant industrial user shall be allowed to discharge, the Chief Plant Operator and/or Superintendent of Sewers shall consider:
(1) 
The quantities of each substance that are uncontrollable because they occur naturally in wastewater;
(2) 
The quantities of each substance that are anthropogenic but are nonetheless uncontrollable;
(3) 
Historical discharge trends;
(4) 
Past pollution control efforts of each user as compared to other dischargers of the same substance;
(5) 
Potential for growth in the POTW service area;
(6) 
Potential for more restrictive regulatory requirements to be placed on the POTW discharge or sludge disposal or sludge reuse method; and
(7) 
Treatability of the substance. The Chief Plant Operator and/or Superintendent of Sewers shall apply a 15% safety factor protective of the POTW.
B. 
Permits issued in accordance with this section may allow for discharges in excess of limitations set forth under § 257-73.
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 Chief Plant Operator and/or Superintendent of Sewers:
(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 Town desires, as a result of discharge of wastewater at the above-prescribed concentration limitations;
(4) 
Municipal employees or the public will be endangered; or
(5) 
Air pollution odor and/or groundwater pollution will be caused.
B. 
The limitations on wastewater strength or mass discharge shall be recalculated not less frequently than once every five years. The results of these calculations shall be reported to the Town Board. 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.
The Chief Plant Operator/Superintendent of Sewers shall have the authority to copy any record related to wastewater discharges to the POTW.
A. 
Except where expressly authorized to do so by an applicable pretreatment standard or requirement, no user shall ever increase the use of 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 or requirement.
B. 
The Chief Plant Operator and/or Superintendent of Sewers may impose mass limitations on users who are using dilution to meet applicable pretreatment standards or requirements, or in other cases when the imposition of mass limitations is appropriate.
Grease, oil and sand interceptors shall be provided when, in the opinion of the Chief Plant Operator and/or Superintendent of Sewers, 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 a type and capacity approved by the Chief Plant Operator and/or Superintendent of Sewers and shall be located to be easily accessible for cleaning and inspection. Such interceptors shall be inspected, cleaned, and repaired regularly, as needed, by the owner, at his expense.
The Town Board may reject a user's wastewater, on the recommendation of the Chief Plant Operator and/or Superintendent of Sewers, when it has been determined that the wastewater contains substances or possesses characteristics which have a deleterious effect on the POTW and its processes or on the receiving water, or which constitute a public nuisance or hazard to workers' health and safety.
