(A)   General prohibitions. No user shall introduce or cause to be introduced into the POTW any pollutant or wastewater which causes pass through or interference. These general prohibitions apply to all users of the POTW whether or not they are subject to categorical pretreatment standards or any other national, state, or local pretreatment standards or requirements.
   (B)   Specific prohibitions. No user shall introduce or cause to be introduced into the POTW the following pollutants, substances, or wastewater:
      (1)   Pollutants which create a fire or explosive hazard in the POTW, including, but not limited to, wastestreams with a closed-cup flashpoint of less than 140 degrees Fahrenheit (60 degrees Celsius) using the test methods specified in 40 CFR 261.21;
      (2)   Wastewater having a pH less than 6.0, or otherwise causing corrosive structural damage to the POTW or equipment;
      (3)   Solid or viscous substances in amounts or of such size capable of obstructing the flow in the POTW resulting in interference;
      (4)   Pollutants, including oxygen-demanding pollutants (BOD, 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 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 degrees Fahrenheit (40 degrees Celsius);
      (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 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 Director of Engineering and Utilities in accordance with § 50.038;
      (9)   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 to be in noncompliance with sludge use or disposal criteria, guidelines or regulations developed under Section 405 of the Clean Water 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;
      (10)   Wastewater causing, alone or in conjunction with other sources, the treatment plant’s effluent to fail toxicity testing, violate its NPDES/KPDES permit and or sludge disposal system permit;
      (11)   Any waters or wastes containing any identifiable chlorinated hydrocarbons, in quantities or concentrations capable of interfering with or passing through the POTW;
      (12)   Any waters or wastes containing acid metallic pickling wastes or concentrated plating solutions.
   (C)   Pollutants, substances, or wastewater prohibited by this section shall not be processed or stored in such a manner that they could be discharged to the POTW.
