(c) Any wastewater having a pH less than 6.5 or more than 9.0 or wastewater having any other corrosive property capable of causing damage or hazard to structures or equipment of the POTW or to employees of the City. (d) Any wastewater containing toxic pollutants in sufficient quantity, either singly or by interaction with other pollutants, to interfere with any wastewater treatment process, constitute a hazard to humans or animals, create a toxic effect in the receiving waters of the POTW, to contaminate the sludge of the POTW, or to exceed the limitation set forth in a Categorical Pretreatment Standards. A toxic pollutant shall include but not be limited to any pollutant identified pursuant to Section 307 (a) of the Act. (e) Any noxious or malodorous liquids, gases, or solids which either singly or by interaction with other wastes are sufficient to create a public nuisance or hazard to life or are sufficient to prevent entry into the sewers for maintenance and repair or for sampling or monitoring. (f) Any substance which may cause the POTW's effluent or any other product of the POTW such as 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 non-compliance with sludge use or disposal criteria, guidelines or regulations developed under Section 405 of the Act; any criteria or 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, or State criteria applicable to the sludge management method being used.

(i) Any wastewater with turbidity exceeding one hundred and fifty nephelometric turbidity units. (j ) Any wastewater having a temperature which will 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 40 degrees C (104 degrees F). (k) Any pollutants, including oxygen demanding pollutants (BOD, etc.) released at a flow rate and/or pollutant concentration which a user knows or has reason to know will cause interference to the POTW. (1) Any wastewater containing any radioactive wastes or isotopes of such halflife or concentration as may exceed limits established by applicable State or Federal regulations. (m) Any wastewater which causes a hazard to human life or creates a public nuisance. (n) Any slug loads. In no case shall a slug load have a flow rate or contain concentration or quantities of pollutants that exceed for any time period longer than fifteen (15) minutes more than five (5) times the average twenty-four (24) hour concentration, quantities, or flow during normal operation. -8-
