No 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 or cause pass-through of a pollutant(s) to the receiving stream. These general prohibitions apply to all users of a POTW whether or not the user is subject to Federal Categorical Pretreatment Standards or any other federal, state, or local pretreatment standards or requirements. A user shall not contribute the following substances to the POTW:
(A) Any liquids, solids or gasses 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 a wastestream exhibit a closed cup flashpoint of less than one-hundred forty degrees (140°) Fahrenheit (sixty (60°) degrees Centigrade) using the test methods specified in 40 CFR 261.21. Prohibited materials include, but are not limited to, gasoline, kerosene, naphtha, benzene, toluene, xylene, ethers, alcohols, ketones, aldehydes, peroxides, chlorates, perchlorates, bromates, carbides, hydrides, and any other substances which have a closed cup flash point of one-hundred forty (140°) degrees Fahrenheit (sixty (60°) degrees Centigrade) or less, and any substance which the city, the state, or EPA has notified the user is a fire hazard or a hazard to the sewer system.
(B) Any waters or wastes having a Ph lower than six (6) or higher than nine (9) or having any other corrosive property(s) capable of causing damage or hazard to structures, equipment, and personnel of the POTW.
(C) Any slug load or pollutants, including oxygen demanding pollutants, released at a flow or concentration that will cause interference with the POTW's operation.
(D) Solid or viscous substances in quantities or of such size capable of causing obstruction to the flow in sewers, or other interference with the proper operation of the wastewater facilities.
(E) Any wastewater having a temperature which will inhibit biological activity in the POTW treatment plant resulting in interference, but in no case wastewater with a temperature at the introduction into the POTW that will result in a treatment plant influent temperature which exceeds one-hundred and four (104°) degrees Fahrenheit (forty (40°) degrees C).
(F) Any pollutant(s) which, either alone or by interaction with other substances, produce toxic gases, vapors or fumes within the POTW in a quantity that may cause acute worker health and safety problems.
(G) Any substance which may cause the POTW's effluent or any other product of the POTW such as residues, sludges, or scum to be unsuitable for reclamation and reuse or to interfere with the reclamation process where the POTW is pursuing a reuse and reclamation program. In no case shall a substance discharged to the POTW cause the POTW to be in non-compliance 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 Substances Control Act, or state criteria applicable to the sludge management method being used.
(H) Any substance which causes the POTW to violate its NPDES/KPDES permit, sludge disposal permit or the water quality standards of the receiving stream.
(I) Petroleum oil, non-biodegradable cutting oil, or products of mineral oil origin in amounts that will cause interference of pass-through at the POTW.
(J) Any trucked or hauled pollutants, except at discharged points designated by the superintendent.
