<br />Section 10-2.2 Prohibited Discharge Standards.
<br />
<br />General Prohibitions. No user shall contribute or cause to be contributed
<br />into the POTW, directly or indirectly, any pollutant or wastewater which
<br />causes interference or pass through. These general prohibitions apply to all
<br />users of the POTW whether or not the user is a significant industrial user or
<br />subject to and National, State, or local pretreatment standards or
<br />requirements.
<br />
<br />Specific Prohibitions. No user shall contribute or cause to be contributed
<br />into the POTW the following pollutants, substances, or wastewater:
<br />
<br />Explosive mixtures. Pollutants which create a fire or explosive hazard
<br />in the POTW, including, but not limited to, wastestreams with a closed
<br />cup flashpoint of less than one hundred forty (140) degrees Fahrenheit
<br />(sixty (60) degrees Celsius) using the test methods specified in 40 CFR
<br />261.21.
<br />
<br />Solid or Viscous Substances. Solid or viscous substances in amounts
<br />which will cause obstruction of the POTW resulting in interference but
<br />in no case solids greater than one half inch in any dimension.
<br />Prohibited materials include but are not limited to: grease,
<br />uncommunited garbage, animal guts or tissues, paunch manure bones,
<br />hair, hides or fleshings, entrails, whole blood, feathers, ashes
<br />cinders, sand, spent lime, stone or marble dust, metal, glass, straw,

<br />facility, and similar substances.
<br />
<br />Petroleum, cutting or mineral oils. Petroleum oil, nonbiodegradable
<br />cutting oil, or products of mineral oil origin, in amounts that will
<br />cause interference or pass through.
<br />
<br />Corrosive Wastes. Any wastewater having a pH less than 5.0 or more
<br />than 9.0 or wastewater having any other corrosive property capable of
<br />'causing damage to the POTW or equipment.
<br />
<br />Excessive Discharge Rate and/or Conceutration. Any wastewater
<br />containing pollutants, including oxygen-demanding pollutants, (B)D,
<br />etc.) in sufficient quantity, (flow or concentration) either singly or
<br />by interaction with other pollutants, to cause interfere with the POTW.
<br />
<br />Temperature Limit. Any wastewater having a temperature greater than
<br />one hundred fifty (150) degrees Fahrenheit (sixty-six (66) degrees
<br />Celsius) or which will inhibit biological activity in the POTW
<br />treatment plant resulting in interference, but in no case wastewater
<br />which causes the temperature at the introduction into the treatment
<br />plant to exceed one hundred four (104) degrees Fahrenheit (forty (40)
<br />degrees Celsius).
<br />
<br />7o
<br />
<br />Toxic Cases. Any pollutants which result in the presence of toxic
<br />gases, vapors, or fumes within the POTW in a quantity that may cause
