No person shall discharge or cause to be discharged any stormwater, foundation drainwater, groundwater, roof runoff, surface drainage or unpolluted industrial cooling waters to any sewer connected to the JRSB's POTW.
No industrial user shall contribute or cause to be contributed, 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 industrial users of a POTW whether or not the industrial user is subject to pretreatment standards or any other national, county, state or local pretreatment standards or requirements. An industrial user may not contribute the following substances to any POTW:
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 cause fire or explosion or be injurious in any other way to the POTW or to the operation of the POTW. At no time shall two successive readings on an 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. The explosion hazard test method shall be conducted by the closed-cup flash point method as defined in 40 CFR § 261.21. Prohibited materials include, but are not limited to, gasoline, kerosene, naphtha, benzene, xylene, ethers, alcohols, ketones, aldehydes, peroxides, chlorates, perchlorates, bromates, carbides, hydrides and sulfides and/or any other substances which the JRSB, the state and/or the EPA has notified the industrial user are a fire hazard or a hazard to the system.
Solid or viscous substances which may cause obstruction (to the flow in a sewer) or other interference with the operation of the POTW, such as, but not limited to: grease, garbage with particles greater than 1/2 inch in any dimension, animal guts or tissues, paunch manure, bones, hair, hides, fleshings, entrails, whole blood, feathers, ashes, cinders, sand, spent lime, stone dust, 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 of fuel or lubricating oil, mud, glass-grinding or polishing wastes.
Any waters or wastes having a pH lower than 5.5 or higher than 9.0 or having any other corrosive properties capable of causing damage or hazard to sewers, structures, equipment or personnel of the POTW.
Any wastewater containing toxic pollutants in sufficient quantity (either singly or by interaction with other pollutants) to cause injury to or interfere with any wastewater treatment process; to constitute a hazard to humans or animals; to create a toxic effect in the receiving waters of the POTW; and/or to exceed the limitation set forth in a pretreatment standard. A "toxic pollutant" shall include, but not be limited to, any pollutant identified pursuant to Section 307(a) of the Act.
Any noxious or malodorous liquids, gases or solids which, either singly or by interaction with other wastes, are sufficient to create a public nuisance or hazard to life or are sufficient to prevent entry into the sewers for maintenance and repair.
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 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, the Toxic Substance Control Act or state criteria applicable to the sludge management method being used.
Any substance which will cause the POTW to violate its NPDES and/or SPDES permit or the receiving water quality standards.
Any wastewater with objectionable color which is not removed in the treatment process, such as, dye wastes and vegetable tanning solutions.
Any wastewater having a temperature which will inhibit biological activity in the POTW which results in interference. In no case shall wastewater with a temperature, at the introduction into the POTW, exceeding 40° C. (104° F.) be contributed to the POTW unless the POTW is designed to accommodate such temperature.
Any pollutant, including oxygen demanding pollutants (BOD, etc.) released in a discharge at a slow rate and/or pollutant concentration which will cause interference with the POTW.
Any slug load as defined in Article IV of this law.
Any wastewater containing any radioactive wastes or isotopes of such half-life or concentration as may exceed limits established by the Executive Director in compliance with applicable state or federal regulations.
Any wastewater which causes a hazard to human life or creates a public nuisance.
Waste streams with a closed cup flash point of less than 140° F.
Pollutants causing toxic gases, vapors and fumes.
Oil in amounts causing pass-through or interference.
Acceptance of trucked and hauled waste only at designated points.
When the JRSB determines that an industrial user(s) is contributing to the POTW any of the above-enumerated substances in such amount as to interfere with the operation of the POTW, the Executive Director shall advise the industrial user(s) of the impact of the contribution on the POTW and develop effluent limitation(s) for such industrial user(s) to correct the interference with the POTW.
Grease interceptors.
Location. Establishments, including, but not limited to, restaurants, institutions and catering halls, which have kitchen facilities and discharge quantities of fats or grease, are required to include an appropriately sized external grease interceptor as part of their building lateral.
Piping installation. Separate waste lines for the sanitary and kitchen flow are required with the grease trap located on the kitchen waste lines. Sanitary wastes shall not be discharged into the interceptor.
Size requirements.
Flow figures are calculated based upon 50 gallons per seat or verified flow from kitchen facilities.
Gallons per day
Liquid Depth
2,000 gallons or less
2,000 to 6,000
6,000 or more
For other than food preparation facilities, unit size will be determined based upon an evaluation of the anticipated discharge characteristics.
Exterior installation requirements.
All grease interceptors shall be brought to grade with a cast-iron frame and cover located over the influent and effluent tee fittings.
The interceptor base shall be a monolithic precast concrete structure. The interceptor structure shall be rated for a waterwheel load.
Pipe supports and fasteners within interceptor shall be stainless steel.
Effluent shall be drawn from one foot above the bottom of the interceptor through a dip pipe.
The interceptor shall be installed in an accessible location for pumping contents into a tanker truck for transport and disposal.
A difference in elevation between the inlet invert and the outlet invert of three inches to six inches shall be provided.
Interceptor inlet and outlet piping penetrations shall be watertight.
Provide one foot of clear distance between static liquid level and the underside of the top slab.
Interceptor piping shall be a six-inch diameter minimum.
The slope of the influent piping shall be 1/4 inch per foot minimum.
Testing. Conduct exfiltration test on installed interceptor; plug inlet and outlet pipes; fill interceptor with water to top of inlet pipe. The liquid level shall then be measured under supervision of the Joint Regional Sewerage Board. In this test, a second measurement shall be made at least 24 hours after initial measurement. Exfiltration shall be measured as the drop of water level in the interceptor. The maximum allowable quantity of leakage is one gallon per 24 hours. If leakage exceeds the allowable rate, then necessary repairs or replacements shall be made. The test shall be conducted until acceptable results are achieved.
Interior locations.
Due to actual field conditions, installation of an interior grease interceptor may be considered.
Submit documentation for review that indicates the proposed interior interceptor(s) meet the following requirements:
Vented flow-control fittings shall be installed to insure that flow capacity of the grease interceptor, as specified by the manufacturer, is not exceeded. Flow-control valves and/or fittings that are manually adjustable may not be used to limit flow to an interceptor.
Grease interceptors must have a retention capacity, in pounds, of at least twice the numerical flow through rating in gallons per minute.
Grease interceptors shall remove an average of 90% or more of the grease or other extractable matter in the wastewater.
The temperature of water entering a grease interceptor shall not exceed 180° F.
All grease interceptors must be readily accessible for inspection by duly authorized employees of the Town.
Grease interceptors for scraper sinks shall have a minimum retaining capacity of at least 30 pounds.
Discharge from automatic dishwashers may be tributary to a grease interceptor.
Discharges from high-temperature sanitizer cycles of automatic dishwashers or from dedicated sanitation compartments of sinks need not be tributary to a grease interceptor.
Operation and maintenance.
Grease interceptors shall be properly installed, maintained and operated to insure that the requirements of this subsection and other applicable sections of the regulations are met. This shall include routine cleaning and grease removal from the interceptor at a minimum of one time every three months, as needed, to insure the proper operation of the interceptors. Further, records, receipts and any other documentation of the pump-out services are to be forwarded to the Joint Regional Sewerage Board, Executive Director or his approved designee by such establishments.
