<br />with any sewage treatment process, constitute a hazard to humans or animals, create a public
<br />nuisance or create any hazard in the receiving waters of the sewage treatment plant.
<br />(3) Any waters or wastes having a pH lower than 3:5 5_0 or having any corrosive
<br />property capable of causing damage or hazard to structures, equipment collection systems or
<br />personnel of the sewage works, or that interferes with any treatment process.
<br />(4) Solid or viscous substances in quantities or of such size capable of causing
<br />obstruction to the flow in sewers, or other interference with the proper operation of the
<br />sewage works such as, but not limited to ashes, cinders, sand, mud, straw, shavings, metal,

<br />the Federal Water Pollution Control Act, as amended.
<br />(6) Any pollutant, including oxygen-demanding pollutants (BOD, etc.), released in a
<br />discharge at a flow rate ancUor pollutant concentration which, either singly or by interaction
<br />with other pollutants, will cause interference with the POTW.
<br />(7) Wastewater or any liquid having a temperature greater than one hundred fifty (150)
<br />degrees Fahrenheit (sixty-five (65) degrees Celsius), or which will inhibit biological activity
<br />in the treatment plant resulting in interference, but in no case wastewater or liquid which
<br />causes the temperature at the introduction into the treatment plant to exceed one hundred
<br />four (104) degrees Fahrenheit (forty (40) degrees Celsius).
<br />(8) Trucked or hauled pollutants, except at discharge points designated by the Director.
<br />(9) Any wastewater, liquid or other waste containing concentrations of the following
