  "definition": "Prohibitions that apply to each IU introducing pollutants into a POTW regardless of whether the IU is subject to other national pretreatment standards or any national, state, or local pretreatment requirements. The following pollutants must not be introduced into a POTW: 1) Pollutants that create a fire or explosion hazard in the POTW, including wastestreams with a closed cup flashpoint of less than 140 degrees Fahrenheit (°F) or 60 degrees Celsius (°C) using the test methods specified in 40 CFR 261.21. 2) Pollutants that will cause corrosive structural damage to the POTW, but in no case discharges with pH lower than 5.0, unless the POTW is specifically designed to accommodate such discharges. 3) Solid or viscous pollutants in amounts that will cause obstruction to the flow in the POTW resulting in interference. 4) Any pollutant, including oxygen-demanding pollutants (biochemical oxygen demand and the like) released in a discharge at a flow rate or concentration that will cause interference with the POTW. 5) Heat in amounts that will inhibit biological activity in the POTW resulting in interference, but in no case heat in such quantities that the temperature at the POTW treatment plant exceeds 104 °F (40 °C) unless the Approval Authority, at the POTW’s request, approves alternative temperature limits. 6) Petroleum oil, nonbiodegradable cutting oil, or products of mineral oil origin in amounts that will cause interference or pass through. 7) Pollutants that result in the presence of toxic gases, vapors, or fumes within the POTW in a quantity that could cause acute worker health and safety problems. 8) Any trucked or hauled pollutants, except at discharge points designated by the POTW.",
