PART IV — STANDARD CONDITIONS
<br />A. Prohibited Discharges
<br />1. General prohibitions. No permittee shall introduce or cause to be introduced into the POTW any
<br />pollutant or wastewater which causes Pass Through or Interference.
<br />2. Specific prohibitions. No permittee shall introduce or cause to be introduced certain pollutants,
<br />substances, or wastewater into any public sewers or directly or indirectly into the POTW. Those
<br />pollutants, substances or wastewater prohibited by this subsection shall not be processed or stored in
<br />such a manner that they could be discharged to the POTW. The following described pollutants are
<br />expressly prohibited:
<br />a. Any gasoline, benzene, naphtha, fuel oil or other pollutants which create afire or explosive hazard
<br />to the POTW, including, but not limited to, wastestreams with a closed -cup flashpoint of less than
<br />one hundred forty (140) degrees Fahrenheit (sixty (60) degrees Celsius) using the test methods
<br />specified in 40 CFR 261.21.
<br />b. Any wastewater containing toxic pollutants in sufficient quantity, either singly or by interaction
<br />with other pollutants, to injure or interfere with any wastewater treatment process, constitute a
<br />hazard to humans or animals, create a toxic effect in the receiving waters of the wastewater works,
<br />or to exceed the limitations set forth in the applicable Federal Categorical Pretreatment Standards
<br />or other pretreatment standards or regulation issued by the EPA or the IDEM. Toxic pollutants
<br />are identified pursuant to Section 307(a) of the Federal Water Pollution Control Act, as amended.
<br />c. Solid or viscous substances in quantities or of such size capable of causing obstruction to the flow
<br />in sewers, or other interference with the proper operation of the sewage works such as, but not
<br />limited to ashes, cinders, sand, mud, straw, shavings, metal, glass, rags, feathers, tar, plastics,
<br />wood, unground garbage, whole blood, paunch manure, hair and fleshings, entrails, paper, dishes,
<br />cups, milk containers, etc., either whole or ground by garbage grinders.
<br />d. Any pollutant, including oxygen -demanding pollutants (BOD, etc.), released in a discharge at a
<br />flow rate and/or pollutant concentration which, either singly or by interaction with other
<br />pollutants, will cause interference with the POTW.
<br />e. Wastewater or any liquid having a temperature greater than one hundred fifty (150) degrees
<br />Fahrenheit (sixty-five (65) degrees Celsius), or which will inhibit biological activity in the
<br />treatment plant resulting in interference, but in no case wastewater or liquid which causes the
<br />temperature at the introduction into the treatment plant to exceed one hundred four (104) degrees
<br />Fahrenheit (forty (40) degrees Celsius).
<br />f. Trucked or hauled pollutants, except at discharge points designated by the Director.
<br />g. Any pollutant that results in the presence of toxic gases, vapors, or fumes within the POTW in a
<br />quantity that may cause acute worker health and safety problems.
