All users of the district 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 and/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 pass through or cause interference with the operation or performance of the POTW 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.
[Amended 11-8-2006 by L.L. No. 13-2006]
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 (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.); pollutants, including but not limited to wastestreams which a closed-cup flashpoint of less than 140° F. (60° C.) using the test methods specified in 40 CFR 261.21; unless explicitly allowable by a written permit, 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 district, 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 5.0 or greater than 11.0, 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)

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, fetus, products of abortion, surgical specimens, 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. The installation of garbage grinders equipped with a motor greater than 3/4 horsepower 0.75 (horsepower) shall be only by permit issued by the Executive Director.
[Amended 11-8-2006 by L.L. No. 13-2006]
(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 are sufficient 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 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 25 mg/l or in amounts that will cause interference or pass through.
(8) 
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, unless explicitly allowable by written permit.
(9) 
Any substance, including oxygen-demanding pollutants (BOD, COD, etc.) or chlorine 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 of POTW, or cause a significant additional load on the sewage treatment works, except as provided under Article X.
(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) 
Any solid, liquid, vapor or gas having a temperature higher than 65° C. (150° F.), or which will inhibit biological activity in the treatment plant resulting in interference. However, such materials shall not cause the POTW treatment plant influent temperature to be greater than 40° C. (104° F.). The Executive Director reserves the right, in certain instances, to prohibit wastes at temperatures lower than 65° C.
(12) 
Unusual flow rate or concentration of wastes constituting "slugs," as defined herein.
[Amended 11-8-2006 by L.L. No. 13-2006]
(13) 
Any wastewater containing any radioactive wastes, except as approved by the Executive Director and in compliance with applicable state and federal regulations. Any institution or industry discharging radioactive material or fission products must be registered with the sewer district as well as 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 380: Rules and Regulations for the Prevention and Control of Environmental Pollution by Radioactive Materials, and at all times within the limits set by this and other County, state or federal agencies.
(14) 
Any wastewater which causes a hazard to human life or which creates a public nuisance, either by itself or in combination, in anyway, with other wastes.
(15) 
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 discharged to the POTW cause the POTW to be in noncompliance with the sludge use or disposal criteria, guidelines or regulations developed under Section 405 of the Act, any criteria, guidelines or regulations affecting sludge use or disposal developed pursuant to the Solid Waste Disposal Act, the Clean Air Act or the Toxic Substances Control Act or local criteria applicable to the sludge management method being used.
(16) 
Any water or wastes containing strong acid metal, pickling wastes or concentrated plating solutions whether neutralized or not.
(17)

(18) 
Waters or wastes containing substances which are not amenable to treatment or reduction in concentration by the sewage treatment plant process employed, or amenable to treatment only to such a degree that the sewage treatment plant effluent will violate the most current NPDES and/or state disposal system permit or the receiving water quality standards.
(19) 
Stormwater, surface water, groundwater, artesian well water, roof runoff, subsurface drainage, swimming pool drainage, condensate, deionized water, noncontact cooling water which has no chance of becoming contaminate or polluted, and unpolluted wastewater, unless specifically authorized by the Executive Director.
(20)

The categorical pretreatment standards found in 40 CFR Chapter 1, Subchapter N, Parts 405-471, are hereby incorporated.
A. 
Where a categorical pretreatment standard is expressed only in terms of either the mass or the concentration of a pollutant in wastewater, the Executive Director may impose equivalent concentration or mass limits in accordance with 40 CFR 403.6(c).
B. 
When wastewater subject to a categorical pretreatment standard is mixed with wastewater not regulated by the same standard, the Executive Director may impose an alternate limit using the combined wastestream formula in 40 CFR 403.6(e).
C. 
A user may obtain a variance 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.
D. 
A user may obtain a net gross adjustment to a categorical standard in accordance with 40 CFR 403.15. 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 chapter for sources in that subcategory, shall immediately supersede the limitation imposed under this chapter. The Executive Director shall notify all affected users of the applicable reporting requirements under 40 CFR 403.12.
A. 
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, except by permit or as provided for in § 345-74. Concentration limits are applicable to wastewater effluents at the point just prior to discharge into the POTW (end of pipe concentrations).

(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 and oil and grease, which shall be determined using grab samples. For pH and oil and grease, the limit is instantaneous, not an average daily limit. The average daily limit means the average of all measurements during a calendar day or twenty-four-hour period.
B. 
The limits for organic pollutants other than those listed in this section and higher than the minimum detection limits as established by 40 CFR 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 Executive Director 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.
C. 
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.
[Amended 11-8-2006 by L.L. No. 13-2006]
The Executive Director 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 Executive Director 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 Executive Director shall consider the following:
A. 
The quantities of each substance that are uncontrollable because they occur naturally in wastewater.
B. 
The quantities of each substance that are anthropogenic but are nonetheless uncontrollable.
C. 
Historical discharge trends.
D. 
Past pollution control efforts of each user as compared to other dischargers of the same substance.
E. 
Potential for growth in the POTW service area.
F. 
Potential for more restrictive regulatory requirements to be placed on the POTW discharge or sludge disposal or sludge reuse method.
G. 
Treatability of the substance. The Executive Director shall apply a 15% safety factor protective of the POTW.
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 Executive Director:
(1) 
The limitations in this chapter are not sufficient to protect the POTW;
(2) 
The limitations in this chapter arc 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 district 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 District 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.
A. 
Except where expressly authorized to do so by an applicable pretreatment standard, 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.
[Amended 11-8-2006 by L.L. No. 13-2006]
B. 
The Executive Director 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.
