A. General prohibitions. No user shall introduce or cause to be introduced, directly or indirectly, to a sanitary sewer system any pollutant or wastewater that causes pass-through or interference with the operation or performance of a sanitary sewer system. These general prohibitions apply to all users of a sanitary sewer system whether or not the user is subject to federal categorical pretreatment standards or any other federal, state or local pretreatment standards or requirements.
B. Specific prohibitions. No user shall introduce or cause to be introduced into a sanitary sewer system the following:
(1) Pollutants that create a fire or explosive hazard in a sanitary sewer system, including, but not limited to, wastestreams with a closed-cup flashpoint of less than 140ºF (60ºC) using the test methods specified in 40 CFR 261.21.
(2) Wastewater having a pH less than 6.0, or more than 9, or otherwise causing corrosive structural damage to a sanitary sewer system.
(3) Solid or viscous substances in amounts which will cause obstruction of the flow in a sanitary sewer system resulting in interference, but in no case solids greater than ½ inch in any dimension.
(4) Pollutants, including oxygen-demanding pollutants (BOD, etc.), 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 a POTW.
(5) Wastewater having a temperature greater than 120ºF, or which will inhibit biological activity in a POTW resulting in Interference, but in no case wastewater which causes the temperature at the introduction into a POTW to exceed 104ºF (40ºC).
(6) Petroleum oil, nonbiodegradable cutting oil, or products of mineral oil origin, in amounts that will cause interference or pass through.
(7) Pollutants which result in the presence of toxic gases, vapors, or fumes within a sanitary sewer system in a quantity that may cause acute worker health and safety problems.
(8) Trucked or hauled pollutants, except at discharge points designated by the operator.
(9) Noxious or malodorous liquids, gases, solids, or other wastewater 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 maintenance or repair.
(10) Wastewater which imparts color which cannot be removed by the treatment process, such as, but not limited to, dye wastes and vegetable tanning solutions, which consequently imparts color to a POTW’s effluent, thereby violating the operator’s NPDES permit.
(11) Wastewater containing any radioactive wastes or isotopes except in compliance with applicable state or federal regulations.
(12) Stormwater, surface water, ground water, artesian well water, roof runoff, subsurface drainage, swimming pool drainage, condensate, deionized water, noncontact cooling water, and unpolluted wastewater, unless specifically authorized by the Township and the operator.
(13) Sludges, screenings, or other residues from the pretreatment of industrial wastes.
(14) Medical Wastes, except as specifically authorized by the operator a wastewater discharge permit.
(15) Wastewater causing, alone or in conjunction with other sources, a POTW effluent to fail toxicity test.
(16) Detergents, surface-active agents, or other substances which that might cause excessive foaming in a POTW.
(17) Fats, oils, or greases of animal or vegetable origin in concentrations greater than 50 mg/l or that concentration otherwise specified by the operator.
(18) Wastewater causing two readings on an explosion hazard meter at the point of discharge into the POTW, or at any point in the POTW, of more than 5% or any single reading over 10% of the Lower Explosive Limit of the meter.
(19) Any wastewater which, because of its chemical nature or composition, causes the sewer atmosphere to contain airborne chemical concentrations in excess of concentrations established by the United States Department of Labor, Occupational Safety and Health Administration (OSHA), under 29 CFR 1910, regardless of duration of exposure experienced by any individual, unless specific authorization is granted by the operator.
(20) Any wastewater containing any organic chemical in excess of limits specified by the operator.
(21) Any wastewater where there is a significant likelihood of producing toxic effects to biota in the receiving water of a POTW or a POTW’s effluent.
C. In addition, the following activities are prohibited:
(1) No person shall discharge wastewater into stormwater inlets or through sewer manholes.
(2) No person who generates wastewater at one property shall discharge it at another property without approval from the operator.
(3) No person shall discharge wastewater in quantities or at rates of flow which may have an adverse or harmful effect on or overload an operator’s sewer system or wastewater treatment plant or cause excessive or additional treatment costs.
(4) No person shall discharge a wastewater flow contributing more than the five-day biochemical oxygen demand limitation contributing more than the suspended solids limitations, or having a volume in excess of the specific limitations of the respective operator.
