A. 
No user shall contribute or cause to be contributed, in any manner or fashion, directly or indirectly, any pollutant or wastewater which will interfere with the operation or performance of the POTW. 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.
B. 
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, to the operation of the POTW or to the POTW personnel or the components of the sewer collection system such as pipe, manhole, wetwells, pumps, valves, pump station, etc. At no time shall both of 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 5% nor any single reading be more than 10% of the lower explosive limit (LEL) of the meter. Unless explicitly allowable by a written permit, prohibited materials include, but are not limited to, gasoline, kerosene, naphtha, benzene, toluene, xylene, ethers, alcohols, carbides, hydrides and sulfides, and any other substance which the City of Glen Cove, the Nassau County Department of Health, the state or the EPA has determined to be a fire hazard or hazard to the POTW and/or the sewage collection system.
(2) 
Solid or viscous substances which may cause obstruction to the flow in a sewer or otherwise interfere with the operation of the POTW. 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, unground garbage, wastepaper, wood, plastics, gas, tar asphalt residues, residues from refining or processing fuel or lubricating oil, mud or glass or stone grinding or polishing wastes and paper dishes, cups, milk containers, etc., either whole or processed by garbage grinders.
(3) 
Any wastewater having a pH less than 6.0 or greater than 8.0, or wastewater having any other corrosive property capable of causing damage or hazard to structures, equipment and/or POTW personnel.
(4) 
Any wastewater containing toxic pollutants or poisonous solids, liquids or gases in sufficient quantity, either singly or by interaction with other wastes or pollutants (including heat), to injure or interfere with any wastewater treatment process, constitute a hazard to humans or animals, create a public nuisance or a hazard or a toxic effect in the receiving waters of the POTW or to exceed the limitation set forth in a categorical pretreatment standard or cause the effluent from the POTW not to meet state, interstate or federal requirements for the receiving waters. A toxic pollutant shall include, but not be limited to, any pollutant identified pursuant to § 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 or POTW for their maintenance or repair.
(6) 
Oils and grease. Any commercial, institutional or industrial wastes containing floatable fats, waxes, grease or oils or which become visible solids when the wastes are cooled to 10º C. (50º F.); any petroleum oil, nonbiodegradable cutting oil or products of mineral oil origin in excess of 25 mg/l or in amounts that will cause interference or pass through.
(7) 
Any wastewater which will cause interference or pass through.
(8) 
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.
(9) 
Any solid, liquid, vapor or gas having a temperature higher than 65º C. (150º F.) at the point of discharge or heat in the amounts that inhibit biological activity at the POTW; however, such materials shall not cause the POTW treatment plant influent temperature to be greater than 40º C. (104º F.). The Director reserves the right, in certain instances, to prohibit or limit the discharge of wastes whose maximum temperatures are lower than 65º C.
(10) 
Unusual flow rate or concentration of wastes, constituting slugs.
(11) 
Any wastewater containing any radioactive wastes and isotopes except as approved by the Director, and in compliance with applicable state and federal regulations.
(12) 
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.
(13) 
Any wastewater with a closed cup flash point of less than 140º F. or 60º C. using the test methods specified in 40 CFR 261.21.
(14) 
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.
(15) 
Stormwater, surface water, groundwater, roof runoff, subsurface drainage, unpolluted cooling water or unpolluted industrial process water.
(16) 
Quantities of flow, concentrations or both which constitute a slug as defined herein.
(17) 
Any garbage that has not been properly shredded. Garbage grinders may be connected to sanitary sewers from homes, hotels, institutions, restaurants, hospitals, catering establishments or similar places where garbage originates from the preparation of food in kitchens for the purpose of consumption on the premises or when served by caterers.
(18) 
Any water or wastes which, by interaction with other water or wastes in the public sewer system, release obnoxious gases, form suspended solids which interfere with the collection system or create a condition deleterious to structures and treatment processes.
(19) 
Any wastewaters containing more than 100 mg/l of vegetable or animal based fats, oils or grease.
(20) 
Any industrial wastewater having a color of an intensity in excess of 1,000 platinum-cobalt units. In testing such intensity, samples shall be diluted with distilled water to bring the range within 10 to 50 platinum-cobalt units and judged on a basis of intensity or transmission of light rather than true color (Platinum Cobalt Standard).
(21) 
Any wastes from gasoline or diesel engine cleaning operations.
(22) 
Paints, paint solvents or paint wastes.
(23) 
Any plating bath wastes, formaldehyde and carbide wastes.
(24) 
Wastewaters containing over 2.0 parts per million hydrogen sulfide, sulfur dioxide, nitrous oxide or any halogen.
(25) 
Substances having a flash point lower than 187º F.
(26) 
Any water added for the purpose of diluting wastes which would otherwise exceed applicable maximum concentration limitations.
(27) 
Any pollutant, including oxygen-demanding pollutants released in a discharge at a flow rate and/or pollutant concentrations which will cause interference with the operations of the POTW.
In addition to the requirements under § 225-45, the following pretreatment limits shall be met by all dischargers to the city's POTW:
A. 
Biochemical oxygen demand (BOD) or equivalent oxygen demand may be limited on a permit basis, where deemed necessary by the Director.
B. 
Suspended solids may be limited on an individual basis if deemed necessary by the Director.
C. 
The pH shall be between 6.0 and 8.0.
A. 
In addition to the prohibitions set forth in § 225-45, the pretreatment standards for incompatible pollutants introduced into the city's POTW shall be, for sources within an industrial, commercial or institutional category, that established by the promulgated effluent limitations guideline defining the best practicable control technology currently available pursuant to 40 CFR Part 403.
B. 
No person shall discharge, directly or indirectly, into the POTW wastewater containing any of the following substances in concentrations exceeding those specified below on a daily or an instantaneous basis, except by permit or as provided for in § 225-48. Concentration limits are applicable to wastewater effluents at the point just prior to discharge into the POTW (end of pipe concentrations).

Except for chromium (hexavalent), all concentrations listed for metallic substances shall be as "total metal," which shall be defined as the value measured in a sample acidified to a pH value of two or less, without prior filtration, unless the city's SPDES permit has a limitation expressed on a particular species of a metal, in which case the city may impose a species-specific concentration limit and waive compliance with the above total metal limitation.
All users of the 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 406 through 40 CFR 471.
A. 
Authority of Director.
(1) 
If any wastes or wastewater are discharged or are proposed to be discharged to the POTW, which in the judgment of the Director may have a deleterious effect on the POTW, processes, equipment or receiving waters, may result in the contravention of the effluent requirements of the SPDES permit for the city's wastewater treatment plant, or which otherwise create a hazard to life or constitute a public nuisance, the Director may:
(a) 
Reject the waste;
(b) 
Require pretreatment to an acceptable condition for discharge to the POTW; and/or
(c) 
Require control over the quantities and rates of discharge.
(2) 
If the Director permits the pretreatment or equalization of wastewater flows, the design and installation of the treatment plants and equipment shall be subject to the review and approval of the Director, the Administrator of the United States Environmental Protection Agency, the New York State Department of Environmental Conservation and the Nassau County Department of Health.
B. 
Pretreatment standards. Upon the promulgation of a compliance date for a Federal Categorical Pretreatment Standard for a particular industrial subcategory, the federal standard, if more stringent than limitations imposed under this Part 1 for sources in that subcategory, will supersede the limitations imposed under this Part 1 effective on that compliance date. The Director shall notify all affected users of the applicable reporting requirements under 40 CFR 403.12. Users shall provide necessary wastewater treatment as required to comply with this Part 1 and shall achieve compliance with all federal pretreatment regulations.
C. 
Interceptors. In addition to state requirements, grease, oil and sand interceptors shall be provided when, in the opinion of the Director, they are necessary for the proper handling of liquid wastes containing grease in excessive amounts, or any flammable wastes, sand or other harmful ingredients, except that interceptors shall not be required for private living quarters or dwelling units. Such interceptors shall be of a type and capacity approved by the Director and shall be located as to be readily and easily accessible for cleaning and inspection. Owners shall maintain any interceptor, and shall be responsible for the proper removal and disposal, by appropriate means, of the captured material and shall maintain records of the dates and means of disposal. Any removal and hauling of the collected materials not performed by an owner or his or her personnel shall be performed by licensed waste disposal firms.
D. 
Maintenance of facilities. Where pretreatment or flow-equalizing facilities are provided for any wastewaters, they shall be maintained continually in satisfactory and effective operation by the owner at his or her expense.
E. 
Alternate source of power. Pretreatment or flow equalizing facilities shall be provided with an alternate source of power to operate all such facilities or the owner(s) of the facilities shall indicate in writing to the Director that production shall be controlled or the discharge shall be handled in such a manner that, in the event that the primary source of power to the pretreatment or flow equalizing facilities fails, any discharge to the public sewer will comply with the limits established by the Director pursuant to this Part 1. This alternate power supply must be separate from the existing power source used to operate the pretreatment or flow equalizing facilities and must be operational at the time construction of these facilities has been completed.
F. 
Solids and precipitates; disposal of. Screenings, sludges and other solids and precipitates separated from wastewaters by pretreatment facilities shall be disposed of in such a manner as to prevent entry of such materials into the POTW.
G. 
Bypass prohibited. There shall be no bypass of the pretreatment facilities that allows the entry of untreated or partially treated wastes to the public sewer system.
H. 
Meters and other appurtenances. When required by the Director the owner of any property serviced by a building sewer carrying industrial wastewater shall install a suitable structure together with such necessary meters and other appurtenances in the building sewer to facilitate observation, sampling and measurement of the wastes. Such structure, when required, shall be accessibly and safely located, and shall be constructed in accordance with plans approved by the Director. The structure shall be installed by the owner at his or her expense, and shall be maintained by him or her so as to be safe and accessible at all times.
The Director will establish total mass discharge limits on a pollutant by pollutant basis for any of the substances in § 225-47 for any significant industrial user (SIU) and may establish such limits for any industrial, commercial or institutional users upon a determination that a mass limit would better prevent interference or pass through than the concentration limits contained in § 225-47.
A. 
In determining the total load of each substance that SIU's shall be allowed to discharge, the Director may 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) 
The past pollution control efforts of each significant industrial user as compared to other significant industrial dischargers of the same substance.
(5) 
The potential for growth in the POTW service area.
(6) 
The potential for more restrictive regulatory requirements to be placed on the POTW discharge or sludge disposal or sludge reuse method.
(7) 
The treatability of the substance.
B. 
The Director may apply a minimum safety factor of 15% to be protective of the POTW. Similar factors may apply when the Director seeks to establish mass discharge limits for the other categories of users listed above.
A. 
Limitations on wastewater strength or mass discharge contained in this Part 1 may be supplemented with more stringent limitations when, in the opinion of the Director:
(1) 
The limitations in this Part 1 are not sufficient to protect the POTW;
(2) 
The limitations in this Part 1 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) 
POTW personnel 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 not less frequently than once every five years. The results of these calculations shall be reported to the city. This Part 1 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 Director shall have the authority to copy any record related to the discharge of wastewater by any user to the POTW.
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 or SUO limitation.
The city may reject a user's wastewater, on recommendation of the Director, when it is 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 sewage collection system or which constitute a public nuisance or hazard.
No connections shall be made to any sanitary sewer that are intended to discharge inflow. Such prohibited connections include, but are not limited to, footing drains, roof leaders, roof drains, cellar drains, sump pumps, catch basins, uncontaminated cooling water discharges or other sources of inflow.
Connections which contribute inflow to the sanitary sewers must be disconnected in a fashion approved by the Director.
