Under no circumstances shall any of the following pollutants be introduced from any source of nondomestic discharge to the city’s publicly owned treatment works (POTW):

A. Any other pollutant which may cause pass-through or interference;

B. Pollutants which create a fire or explosion hazard in the POTW, including, but not limited to, waste streams with a closed cup flashpoint of less than sixty degrees Centigrade (one hundred forty degrees Fahrenheit) using the test methods specified in 40 CFR Section 261.21;

C. Pollutants which will cause corrosive structural damage to the POTW, but in no case discharges with a pH of lower than five s.u., unless the treatment facilities are specifically designed to accommodate such discharges;

D. Solid or viscous pollutants in amounts which will cause obstruction to the flow in the POTW, or other interference with the operation of the POTW;

E. Any pollutant, including oxygen demanding pollutants (e.g. BOD), released in a discharge at a flow rate and/or pollutant concentration which will cause interference with any treatment process at the POTW;

F. Heat in amounts which 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 forty degrees Centigrade (one hundred four degrees Fahrenheit) unless the EPA, upon request of the POTW, approves alternate temperature limits;

G. Petroleum oil, nonbiodegradable cutting oil, or products of mineral oil origin in amounts that will cause interference or pass-through at the POTW;

H. 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;

I. Any trucked or hauled pollutants, except at discharge points designated by the POTW; and

J. Any specific pollutant which exceeds a local limitation established by the permittee in accordance with the requirements of 40 CFR Section 403. (Ord. 654 § 1(part), 2004)
