No discharger shall contribute or cause to be discharged, directly or indirectly, any of the following described substances into the POTW or otherwise to the facilities of the City:
(a) Any liquids, solids or gases which by reason of their nature or quantity are, or may be sufficient either alone or by interaction to cause fire or explosion or be injurious in any other way to the operation of the POTW.
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 sixty degrees Centigrade using the test method described in 40 CFR 261.21.
(b) Solid or viscous substances which will or may cause obstruction to the flow in a sewer or other interference with the operation of the POTW.
(Ord. 107-1991. Passed 6-24-91.)
(c) Any wastewater having a pH less than 6.0 or higher than 11.0 or having any other corrosive property capable of causing damage or hazard to structures, equipment or personnel of the system.
(Ord. 117-1993. Passed 6-14-93.)
(Ord. 117-1993. Passed 6-14-93.)
(d) Any wastewater containing toxic pollutants in sufficient quantity, either singly or by interaction, to injure or interfere with any wastewater treatment process, which constitute a hazard to humans or animals, or to exceed the limitation set forth in this chapter. A toxic pollutant includes but is not limited to any pollutant identified in the Priority Pollutant List set forth in Appendix A hereto.
(e) 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.
(f) Any substance which may cause the POTW's effluent or treatment residues, sludges or scums to be unsuitable for reclamation and reuse or to interfere with the reclamation process. In no case shall a substance discharged to the POTW cause the POTW to be in noncompliance with sludge use or disposal criteria, guidelines or regulations developed under Section 405 of the Act; any criteria, guidelines or regulations affecting sludge use or disposal developed pursuant to the Solid Waste Disposal Act, the Clean Air Act, the Toxic Substances Control Act, Resource Conservation and Recovery Act or state standards applicable to the sludge management method being used.
(g) Any substances which will cause the POTW to violate its NPDES and/or other disposal system permits.
(h) Any substance with objectionable color not removed in the treatment process, such as but not limited to, dye waste and vegetable tanning solutions.
(i) Any wastewater having a temperature which will inhibit biological activity in the POTW resulting in interference; but in no case, wastewater with a temperature at the introduction into the POTW wastewater treatment plant which exceeds forty degrees Celsius (104 degrees Fahrenheit).
(j) Any slugload, which means any pollutant, including oxygen demanding pollutants (BOD, etc.), released in a single extraordinary discharge episode of such volume or strength as to cause interference or pass through at the POTW.
(k) Any unpolluted water including, but not limited to, noncontact cooling water, except such water as may be discharged to a sewer which is designated to carry storm water.
(l) Any wastewater containing any radioactive wastes or isotopes of such halflife or concentrations as exceed limits in compliance with applicable state or federal regulations.
(m) Any wastewater which causes a hazard to human life or creates a public nuisance.
(n) Discharges of petroleum oil, nonbiodegradable cutting oil or products of mineral oil origin in amounts that will cause interference or pass through.
(o) Any trucked or hauled pollutants except at discharge points designated by the Director.
(Ord. 107-1991. Passed 6-24-91.)
(Ord. 107-1991. Passed 6-24-91.)
(p) The discharge of hazardous wastes (as defined in Section 1004 of the Resource Conservation and Recovery Act) into a pipeline connected to the public sewer, which is dedicated to only the discharge of hazardous wastes is prohibited. The discharge of hazardous wastes to the headworks of the wastewater treatment plant by truck and rail is also prohibited.
(Ord. 117-1993. Passed 6-14-93.)
When the Director determines that a discharger is contributing any of the above enumerated substances in such amounts as to interfere with the operation of the POTW, the Director shall: advise the discharger of the impact of the contribution on the POTW; and develop effluent limits for such discharger to correct the interference with the POTW.
(Ord. 107-1991. Passed 6-24-91.)
