(A) Generally.

(1) It shall be unlawful for any person to place, deposit, or permit to be deposited in any unsanitary manner on public or private property within the city or in any area under the jurisdiction of the city or into any sewer which connects to the storm sewer system of the city any objectionable wastewater or industrial wastes.

(2) It shall be unlawful to discharge to any natural outlet within the city in any area under the jurisdiction of the city, any wastewater or other polluted waters, except where suitable treatment has been provided in accordance with subsequent provisions of this chapter. No provision of this chapter shall be construed to relieve the owner of a discharge to any natural outlet of the responsibility for complying with applicable state and federal regulations governing such discharge.

(C) Discharge of unpolluted waters into sewer.

(1) No person(s) shall discharge or cause to be discharged through any leak, defect or connection any unpolluted waters such as storm water, ground water, roof runoff, subsurface drainage or cooling water to any sanitary sewer, building sewer, building drain or building plumbing. The Superintendent or his representative shall have the right, at any time, to inspect the inside or outside of buildings or smoke test for connections, leaks, or defects to building sewers and require disconnection or repair of any pipes carrying such water to the building sewer. Such waters shall not be removed through the dual use of a sanitary drain sump or a sump pump to building sanitary sewer. Discharge of such waters by a manual switch?over from sanitary sewer to storm drainage will not be an acceptable method of separation. In case both storm and sanitary sewage is present, separate drainage or pumping system shall be included.

(2) Stormwater, groundwater and all other unpolluted drainage may be discharged to such sewers as are used as storm sewers approved by the Superintendent. Under no circumstances shall sanitary sewage be discharged to a storm sewer.

(3) The owner(s) of any building sewers having such connections, leaks, or defects shall bear all costs incidental to removal of such sources.

(1) No user shall contribute or cause to be contributed, directly or indirectly, any pollutant or wastewater which will interfere with the operation or performance of the POTW. These general prohibitions apply to all such users of a POTW whether or not the user is subject to federal categorical pretreatment standards or any other federal, state or local pretreatment standards or requirements.  A user shall not contribute the following substances to any POTW:

(a) Any liquids, solids or gases which by reason of their nature or quantity are, or may be, sufficient either alone or by interaction with other substances to cause fire or explosion or be injurious in any other way to the POTW or to the operation of the POTW. At no time shall a wastestream exhibit a closed cup flashpoint of less than 140º F. (60º C.) using the test methods specified in 40 CFR 261.21. Prohibited materials include, but are not limited to, gasoline, kerosene, naphtha, benzene, toluene, xylene, ethers, alcohols, ketones, aldehydes, peroxides, chlorates, perchlorates, bramates, carbides, hydrides and any other substances which have a closed cup flashpoint of 140º F. (60º C.) or less, and any substance which the city, state or EPA has notified the user is a fire hazard or a hazard to the sanitary sewer system.

(b) Any waters or wastes having a pH lower, than 6. 0 or higher than 9.5 or having any other corrosive property(s) capable of causing damage or hazard to structures, equipment and personnel of the POTW.

(c) Any slug load or pollutants, including oxygen demanding pollutants, released at a flow or concentration that will cause interference with the POTW's operation.

(d) Solid or viscous substances in quantities or of such size capable of causing obstruction to the flow in sewers, or other interference with the proper operation of the wastewater facilities.

(e) 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 that will result in a treatment plant influent temperature which exceeds 104º F. (40º C.).

(f) Any pollutant (s) which, either alone or by interaction with other substances, produce toxic gases, vapors or fumes within the POTW in a quantity that may cause acute worker health and safety problems.

(g) Any substances which may cause the POTW's effluent or any other product of the POTW such as residues, sludges, or scum to be unsuitable for reclamation and reuse or to interfere with the reclamation process where the POTW is pursuing a reuse and reclamation program. 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, or state criteria applicable to the sludge management method being used.

(h) Any substance which causes the POTW to violate it NPDES/KPDES permit, sludge disposal permit or the water quality standards of the receiving stream.

(i) Petroleum oil, nonbiodegradable cutting oil, or products of mineral oil origin in amounts that will cause interference or pass through at the POTW.

(j) Any trucked or hauled pollutants, except at discharge points designated by the Superintendent.
