(a) It shall be unlawful to cause to be discharged, directly or indirectly, any of the following described substances into the POTW or otherwise to the facilities of the City:
(1) 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, including, but not limited to, wastestreams with a closed cup flashpoint of less than 140 degrees Fahrenheit or 60 degrees Centigrade using the test method specified in 40 CFR 261.21;
(2) 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;
(3) Any wastewater having a pH less than 6.5 or higher than 9.0 or having any other corrosive property capable of causing damage or hazard to structures, equipment or personnel of the system;
(4) Any wastewater containing toxic pollutants in sufficient quantity, either singly or by interaction, to injure or interfere with any wastewater treatment process, constitute a hazard to humans or animals, or to exceed the limitation set forth in this chapter. A toxic pollutant shall include but not be limited to any pollutant identified in the Priority Pollutant List set forth in Appendix A hereto;
(5) Any noxious, malodorous or toxic liquids, gases, vapors, fumes or solids which either singly or by interaction are capable of creating a public nuisance or hazard to life or are sufficient to prevent entry into the sewers for their maintenance and repair, or may cause acute worker health and safety problems;
(6) 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;
(7) Any substance which will cause the POTW to violate its NPDES and/or other Disposal System Permits;
(8) Any wastewater having a temperature which will inhibit biological activity or cause structural damage in the POTW resulting in interference; but in no case, wastewater with a temperature at the introduction into the POTW treatment plant which exceeds 40oC (104oF);
(9) Any slugload;
(10) Any unpolluted water except such water as may be discharged to a sewer which is designated to carry storm water;
(11) Any wastewater containing any radioactive wastes or isotopes of such half- life or concentrations as exceed limits in compliance with applicable State or Federal regulations; or
(12) Any wastewater which causes a hazard to human life or creates a public nuisance.
(13) Any petroleum oil, nonbiodegradable cutting oil or products of mineral oil origin in amounts that may pass through or cause interference.
(14) Hauled septic or industrial wastes except at locations and at times as designated by the Director. Any removal of manhole lids, or other access to the sewer system for the purpose of discharging wastes at times and/or locations other than those designated by the Director, or without the expressed written permission of the Director, shall be considered a violation and shall be subject to enforcement action including fines and penalties subsequently described in Section 933.99.
(b) 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:
(1) Advise the discharger of the impact of the contribution on the POTW; and
(2) Direct the discharger to apply for a permit or a revision to any existing permit pursuant to Section 933.11.
