No user shall contribute or cause to be contributed, directly or indirectly, any pollutant or wastewater which will interfere with performance of the POTW or cause Pass Through to the receiving stream. These general prohibitions apply to all such users of the POTW whether or not the user is subject to National Categorical Pretreatment Standards or any other national, state, or local Pretreatment Standards or Requirements. A user shall not contribute the following substances to the POTW:
(A) 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 the wastewater exhibit a closed cup flashpoint of less than 140 degrees Fahrenheit or 60 degrees Centigrade using the test methods specified in 40 CFR 261.21.
(B) Any waters or wastes having a pH lower than 6.0 S.U. or higher than 9.0 S.U. or having any other corrosive property capable of causing damage or hazard to structures, equipment, and personnel of the POTW.
(C) Any slug load of pollutants, including oxygen-demanding pollutants (BOD, etc.), released at a flow rate and/ or concentration, either individually or by interaction with other pollutants, that will cause interference with the normal operation of the POTW.
(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, (i.e. wood, glass, ashes, sand, cinders, unshredded garbage, etc.).
(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 40°C (104°F).
(F) Any pollutant(s) 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.
(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 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 Substances Control Act, or state criteria applicable to the sludge management method being used.
(H) Any substance which will cause the POTW to violate its NPDES/KPDES Permit and/ or sludge disposal system permit.
(I) Petroleum oil, nonbiodegradable cutting oil, or products of mineral oil origin in amounts that will cause interference or pass through at the POTW.
(J) Any trucked or hauled pollutants except at discharge points designated by the POTW.
