Town of Riverhead, NY Use of Public Sewers

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 STP. The Superintendent may decide that wastes, in addition to those described below, can harm either the sewers, sewage treatment process or equipment, have an adverse effect on the receiving stream or groundwater, as the case may be, or can otherwise endanger life, limb, public property or constitute a nuisance. In forming his opinion as to the acceptability of these wastes, the Superintendent will give consideration to such factors as the quantities of subject wastes in relation to flows and velocities in the sewers, materials of construction of the sewers, nature of the sewage treatment process, capacity of the sewage treatment plant, degree of treatability of wastes in the sewage treatment plant and other pertinent factors. The substances prohibited are:

(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 STP, or to its operation. 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 25% nor any single reading be more than 40% 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, oxylene, ethers, alcohols, carbides, hydrides and sulfides, and any other substance which the county, the state or the EPA has determined to be a fire hazard or hazard to the STP.

(2)

Pollutants listed under Restricted Toxic or Hazardous Materials in Suffolk County Sanitary Code, Article 7.

(3)

Any waters or wastes containing toxic or poisonous solids, liquids or gases in sufficient quantity, either singly or by interaction with other wastes (including, heat), to injure or interfere with any sewage treatment process, constitute a hazard to humans or animals, create a public nuisance or create any hazard in the receiving waters of the sewage treatment plant, including but not limited to cyanides in excess of two milligrams per liter as CN in the wastes as discharged to the public sewer.

(4)

Solid or viscous substances in quantities or of such size as to be capable of causing obstruction to the flow in sewers or other interference with the proper operation of the sewage works. 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 or stone-grinding or polishing wastes.

(5)

Any waters or wastes having a pH lower than 5.5 or greater than 9.5, or wastewater having any other corrosive property capable of causing damage or hazard to structures, equipment and personnel of the sewage works.

(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)

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.

(8)

Any solid, liquid or vapor having a temperature higher than 150° F. (65° C.). The Superintendent reserves the right, in certain instances, to prohibit or limit the discharge of wastes whose maximum temperatures are lower than 150° F.

(9)

Any water or wastes containing fats, wax, grease or oils, whether emulsified or not, in excess of 100 milligrams per liter, or containing substances which may solidify or become viscous at temperatures between 32° F. and 150° F.

(10)

Wastes containing strong acid iron pickling wastes or concentrated plating solutions, whether neutralized or not.

(11)

Any garbage that has not been properly shredded. The installation and operation of any garbage grinder equipped with a motor of 3/4 horsepower or greater shall be subject to the review and approval of the Superintendent.

(12)

Unusual flow rate or concentration of wastes, constituting slugs.

(13)

Any radioactive wastes or isotopes of such half-life or concentration as may exceed limits established by the Superintendent in compliance with applicable county, state or federal regulations.

(14)

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.

(15)

Any wastewater with a closed-cup flashpoint of less than 140° F. or 90° C. using the test methods specified in 40 CFR 261.21.

(16)

Any pollutants which result in the presence of toxic gases, vapors or fumes within the STP in a quantity that may cause acute worker health and safety problems.

(17)

Any waters or wastes containing iron, chromium, copper, zinc and similar objectionable or toxic substances, or wastes exerting an excessive chlorine requirement, to such degree that any such material received in the composite sewage at the sewage treatment works exceeds the limits established by the Superintendent for such materials.

(18)

Materials which exert or cause unusual concentrations of inert suspended solids, such as but not limited to fuller's earth, lime slurries and lime residues, or of dissolved solids, such as but not limited to sodium sulfate.

(19)

Materials which exert or cause unusual BOD, chemical oxygen demand or chlorine requirements in such quantities as to constitute a significant load on the sewage treatment works.

(20)

Waters or wastes containing substances which are not amenable to treatment or reduction by the sewage treatment processes employed or are amenable to treatment only to such degree that the sewage treatment plant effluent cannot meet the requirements of other agencies having jurisdiction over discharge to the receiving waters.

Dilution. 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.

No person shall deposit or permit to be deposited, in any unsanitary manner, on, or within the boundaries of, any public or private property within the district, or in any area under the jurisdiction of said district, any human or animal excrement, garbage or other objectionable waste.

No person shall connect a private sewage system so that sewage flows into a storm sewer or into a drain intended exclusively for stormwater.

No person shall discharge sewage into a well.

It shall be unlawful to discharge to any natural outlet, within the district, or in any area under the jurisdiction of the district, any wastewater or other polluted waters, except when suitable treatment has been provided in accordance with subsequent provisions of this Part 4.

Except as hereinafter provided, it shall be unlawful to construct or maintain any privy, privy vault, cesspool, septic tank or other facility intended or used for disposal of wastewater.

No person shall discharge or cause to be discharged inflow sources, including stormwater, surface water, groundwater, roof runoff, subsurface drainage, uncontaminated cooling water or unpolluted industrial process waters, to any sanitary sewer, as described in § 265-58 of this article.

The owner(s) of all properties used for human occupancy, employment, recreation or other purposes, situated within the district and abutting on any street, alley or right-of-way in which there is now, or may be in the future, located a public sewer of the district, is hereby required at the owner's expense to install suitable sanitary facilities therein, and to connect such facilities directly with the proper public sewer in accordance with the provisions of this Part 4, within 90 days after the date of official notice to do so, provided that said public sewer is within 100 feet of the property line. All expenses for said connection shall be paid for by the owner, including but not limited to, district expenses, engineering and construction costs. All sanitary facilities required to install the connections shall be designed by the consulting engineer for the district, as may be appointed by the Town Board.

If the public sewer line is greater than 100 feet from a property line or the elevation of the property requires the installation of a pump station to transport the sewage to district lines, the requirement to connect may be waived if the district determines that it would cause an undue financial hardship to the property owner.

Where the building is other than a single-family residence, or where the district determines that installation of a private sewage disposal system may create a health hazard and/or contaminate groundwater or surface water, the district may require connection of the building to the public sewer regardless of distance and/or topography.

The district, on the recommendation of the Superintendent, shall have the authority to enter into agreements to accept sewage and other wastes, including pretreated industrial wastes, generated by or discharged from persons outside the service area of the district.

(1)

If the person is a municipality, that municipality shall have enacted a sewer use law as restrictive on the discharge of sewage and other wastes as the restrictions contained in this Part 4.

(2)

If the person is not a municipality, the acceptance shall be made only with the expressed written consent of the Superintendent (the issuance of a permit) setting forth the terms and conditions of such an acceptance.
