(A) No user shall contribute or cause to be contributed, directly or indirectly, any wastewater which will interfere with the performance of the POTW. These general prohibitions apply to all such 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.
(B) A user shall not contribute the following substances to any POTW:
(1) 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 a waste stream exhibit a closed cup flashpoint of less than 140°F (60°C) using the test methods specified in 40 C.F.R. § 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 flashpoint of 140°F (60°C) or less, and any substance which the city, state or EPA has notified the user is a fire hazard or a hazard to the sanitary sewer system;
(2) Any waters or wastes having a pH lower than six or higher than nine and one-half or having any other corrosive property(s) capable of causing damage or hazard to structures, equipment and personnel of the POTW;
(3) Any slug load or pollutants, including oxygen demanding pollutants, released at a flow or concentration that will cause interference with the POTW’s operation;
(4) 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;
(5) 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 104°F (40°C);
(6) 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;
(7) Any substances 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 POWWOW is pursuing a reuse and reclamation program. 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 § 405 of the Act; any criteria, guidelines or regulations affecting sludge use or disposal developed pursuant to the Solid Waste Disposal Act, being 42 U.S.C. §§ 6901 et seq., the Clean Air Act, being 42 U.S.C. §§ 7401 et seq., the Toxic Substances Control Act, being 15 U.S.C. §§ 2601 et seq. or state criteria applicable to the sludge management method being used;
(8) Any substance which causes the POTW to violate its NPDES/KPDES permit, sludge disposal permit or the water quality standards of the receiving stream;
(9) Petroleum oil, non-biodegradable cutting oil or products of mineral oil origin in amounts that will cause interference or pass through at the POTW; and
(10) Any trucked or hauled pollutants, except at discharge points designated by the Superintendent.
