(A) No user shall introduce or cause to be introduced into the authority’s wastewater collection system, including the authority’s POTW, the following pollutants, substances or wastewater:
(1) Pollutants which create a fire or explosive hazard in the POTW, including, but not limited to, waste streams with a closed-cup flashpoint of less than 140°F (60°C) using the text methods specified in 40 C.F.R. § 261.21;
(2) Wastewater having a pH less than 6.0 or more than 10.0 or otherwise causing corrosive structural damage to the POTW or equipment;
(3) Solid or viscous substances in amounts which will cause obstruction of the flow in the POTW resulting in interference (but in no case solids greater than one-half inch in any dimension);
(4) Pollutants, including oxygen-demanding pollutants (BOD, COD and the like), 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 the POTW;
(5) Wastewater having a temperature greater than 104°F (40°C) or which will inhibit biological activity in the treatment plant resulting in interference, but in no case wastewater which causes the temperature at the introduction into the treatment plant to exceed 104°F (40°C);
(6) Petroleum oil, non-biodegradable 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 the POTW in a quantity that may cause acute worker health and safety problems;
(8) Trucked or hauled pollutants, except at discharge points designated by the control authority in accordance with this subchapter;
(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 the treatment plant’s effluent, thereby violating the authority’s NPDES permits;
(11) Wastewater containing any radioactive wastes or isotopes except in compliance with applicable state or federal regulations;
(12) Stormwater, surface water, groundwater, artesian well water, roof runoff, subsurface drainage, swimming pool drainage, condensate, deionized water, noncontact cooling water and unpolluted wastewater, unless specifically authorized by the control authority;
(13) Sludge, screenings or other residues from the pretreatment of industrial wastes;
(14) Medical wastes, except as specifically authorized by the control authority;
(15) Wastewater causing, alone or in conjunction with other sources, the POTW’s effluent to fail a toxicity test;
(16) Detergents, surface-active agents, phosphates or other substances which may cause excessive foaming in the POTW;
(17) Fats, oils or greases of animal or vegetable origin in concentrations greater than 100 mg/l;
(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 substance which will cause the POTW to violate its NPDES and/or state disposal system permit or the receiving water quality standards;
(20) In no case shall a slug load have a flow rate or contain concentration or qualities of pollutants that exceed any time period longer than 15 minutes or contain more than five times the average 24-hour concentration of flow during normal operation or otherwise constitutes a slug discharge; and
(21) The discharge of toxic or hazardous wastes, as defined in the Act or RCRA.
(B) When the control authority determines that a user(s) is contributing to the POTW any of the above-enumerated substances in such amounts as to interfere with the operation of the POTW, the control authority shall advise the township and the user(s) of the impact of the contribution on the POTW; develop effluent limitation(s) for such user to correct the interference with the POTW; and proceed with enforcement pursuant to the provisions of this subchapter.
(C) Pollutants, substances or wastewater prohibited by this section shall not be processed or stored in a manner that they could be discharged to the POTW.
