No person(s) shall contribute or cause to be discharged, directly or indirectly, any of the following described substances into the wastewater disposal system or otherwise to the facilities of the City:
(a) Any liquids, solids, gases or other pollutants including, but not limited to, waste streams with a closed cup flashpoint of less than 140 degrees Fahrenheit or sixty degrees Centigrade using the test method specified in 40 CFR 261.21, 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;
(b) Solid or viscous substances which shall or may cause obstruction to the flow in a sewer or other interference with the operation of the wastewater system;
(c) Any wastewater containing toxic pollutants in sufficient quantity, either singly or by interaction to injure or interfere with any wastewater treatment process, or constitute a hazard to humans or animals or which may cause acute worker health problems;
(d) Any wastewater having pH less than 6.0 or higher than 10.0 or having any other corrosive property capable of causing damage or hazard to structures, equipment or personnel of the system;
(e) Any noxious or malodorous liquids, gases 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;
(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 Substance Control Act or state standards applicable to the sludge management method being used;
(g) Any substance which shall 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 wastes and vegetable tanning solutions;
(i) Any wastewater having a temperature which shall inhibit biological activity in the POTW treatment plant resulting in interference; but in no case, wastewater with a temperature at the introduction into the POTW which exceeds forty degrees Centigrade (104 degrees Fahrenheit);
(j) Any slugload, which shall mean 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 passthrough to the POTW;
(k) Any wastewater containing any radioactive wastes or isotopes of such halflife or concentration which exceeds any applicable state or federal regulations;
(l) Any wastewater which causes a hazard to human life or creates a public nuisance;
(m) Wastewater containing more than 100 mg/1 of petroleum oil, nonbiodegradable cutting oils or product of mineral oil origin but in no case in amounts that will cause passthrough or interference;
(n) Wastewater from industrial plants containing floatable oils, fat or grease;
(o) Any garbage that has not been properly shredded; or
(p) Any substance that exerts a significant chlorine demand. A significant chlorine demand is deemed to be, for the purpose of this section, any and all chlorine- readable material in a unit body of water to which a quantity of chlorine must be added to attain completely satisfied reaction.
(q) Any trucked or hauled pollutants except at discharge points designated by the POTW.
