(1)

Pollutants which create a fire or explosion hazard in the POTW, including, but not limited to, wastestreams with a closed cup flashpoint of less than 140 degrees Fahrenheit or 60 degrees Celsius using the test methods specified in 40 CFR 261.21;

(2)

Pollutants which will cause corrosive structural damage to the POTW, but in no case discharges pH lower than 5.0, unless the works are specifically designed to accommodate such discharges;

(3)

Solid or viscous pollutants in amounts which may, in the opinion of the director, cause obstruction to the flow in the POTW resulting in interference;

(4)

Any pollutant, including oxygen demanding pollutants (BOD, etc.), released in a discharge at a flow rate and/or pollutant concentration which may, in the opinion of the director, cause interference with the POTW;

(5)

Liquid or vapor having a temperature higher than 150 degrees Fahrenheit (65 degrees Celsius) or any substance with heat in amounts which may, in the opinion of the director, inhibit biological activity in the POTW resulting in interference, but in no case heat in such quantities that the temperature at the POTW exceeds 40 degrees Celsius (104 degrees Fahrenheit) unless the administrator, upon request of the POTW, approves the alternate temperature limit;

(6)

Petroleum oil, or petroleum oil products, nonbiodegradable cutting oil or products of mineral oil origin in amounts that may, in the opinion of the director, 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)

Any industrial or domestic waste or wastewater from any tank truck or vehicle into any sewer, manway, manhole, street or public sewage treatment plant within the city without written authorization from the director.
