(A) Unlawful discharges. It shall be unlawful for any person to discharge or cause to be discharged any of the following described water or wastes into the City's wastewater disposal system or into any abandoned or unapproved wastewater disposal system.
(1) Surface waters. Any surface runoff, storm water, groundwater, or cooling water.
(2) Industrial waters. Any industrial process water that does not meet the requirements and limitations set forth in this Chapter.
(3) Temperature. Any surface runoff, storm water, groundwater, cooling water, industrial process water, or water over 140°F.
(4) Obstructing materials. Any water or waste containing visible fat, oil, or grease, or any water or waste containing: ashes, cinders, sand, mud, metal, glass, rags, plastics, wood, lime, slurry, lime residues, chemical residues, paint or ink residues, bulk solids, or any other solid or viscous substance capable of causing obstruction to the flow in wastewater main or service lines or causing other interference with the proper operation of the City's wastewater disposal system.
(5) Explosive materials. Any gasoline, benzene, naphtha, fuel oil, motor oil, mineral spirits, commercial solvent or other flammable or explosive liquid, whether a solid or a gas.
(6) Corrosive materials. Any water or wastes having a pH lower than 6.5 or higher than 8.5, or having any corrosive property capable of causing damage or hazard to structures, equipment, and/or personnel of the City.
(7) Toxic or hazardous materials. Any waters, wastes, or other substances may be discharged in concentrations or quantities that are considered toxic. At any time, at the discretion of the City, any discharge suspected of containing toxicity shall be analyzed using the "48-Hour Acute Toxicity" test with Ceriodaphnia dubia test organisms. The Acute Toxicity test shall be done in accordance with EPA's "Methods for Measuring Acute Toxicity of Effluents and Receiving Water to Freshwater and Marine Organisms, 5th Edition", or most current edition. Oxidants, such as chlorine from drinking water, may interfere with the toxicity tests and must be removed by the testing laboratory in accordance with the above methods, prior to conducting the Acute Toxicity test. For any discharge that is found to be toxic as defined by the City's Standard Discharge Limitations, the City may require the customer, at the customer's expense, to evaluate the source of toxicity and eliminate the source from their discharge.
(8) Radioactive materials. Any waters containing quantities of radioactive substances in excess of presently existing or subsequently acceptable limits for drinking water.
(9) Noxious or malodorous materials. Any noxious or malodorous liquids, gases, or solids which, either singly or by interactions with other wastes, are sufficient to create a public nuisance, or hazard to life or health, that will pass through or interfere with the operation or maintenance of the City's wastewater disposal system, or that are sufficient to prevent entry into the City's wastewater disposal system for its maintenance and repair.
(10) Coloring materials. Any substance with or causing objectionable noticeable color not removed in the City's wastewater treatment system.
(11) NPDES prohibited. Any substance that will cause the City to violate its National Pollutant Discharge Elimination System (NPDES) permit.
(12) Screenings. Any substance that may cause the City's wastewater disposal system's treatment screenings to be unsuitable for landfill disposal.
(13) State regulations. Any discharge that could cause the City to violate current state discharge limitations, including, but not limited to, "Solid Waste Management Regulations," 18 AAC 60; "Water Quality Standards," 18 AAC 70; and "Wastewater Disposal Regulations," 18 AAC 72.
(B) Unauthorized manhole use. It shall be unlawful for any unauthorized person to remove or tamper with any manhole cover, or to discharge or cause to be discharged, any wastewater or other wastes or materials into the City's wastewater disposal system through a manhole or through any other method not authorized by the City.
(C) Connection to City wastewater main line. Septic tank seepage systems and/or cesspool disposal facilities shall not be used, continued, or installed on any parcel of land served by City water where a City sanitary wastewater disposal line is located within three hundred (300) feet of any boundary of the parcel. All owners of developed property shall properly abandon septic tank seepage systems and/or cesspool disposal facilities and connect to the City's wastewater main line and comply with the requirements of this Chapter within nine (9) months after a main line is installed within three hundred (300) feet of the developed property.
(D) Abandoned septic tanks, cesspools, wastewater service lines. Abandoned wastewater service lines, septic tanks, and cesspools shall be cleaned of all septage, inspected, and approved by the City. The service lines shall then be cut and capped at the point the service meets the consumer's property line, and septic tanks and cesspools shall be removed, crushed, or filled with concrete or other inert material approved by the City so as to be rendered unusable for the disposal of any waste or wastewater.
