(A) 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 limits, or in any area under the jurisdiction of the city, any sewerage, human or animal excrement, garbage, or other objectionable waste.
(B) It shall be unlawful to discharge to any natural outlet within the city limits, or in any area under the jurisdiction of the city, any sanitary sewerage, industrial waste, or other polluted waters, except where suitable treatment has been provided in accordance with this subchapter, and all applicable state, and federal, laws and regulations.
(C) No person shall discharge, or cause to be discharged, any stormwater, surface water, groundwater, roof runoff, subsurface drainage, cooling water, or unpolluted industrial process water to any sanitary sewer. Any existing discharge of such waters into sanitary sewers shall be immediately discontinued.
(D) Stormwater, and all other unpolluted drainage, shall be discharged to such sewers as are specifically designated as storm sewers, or to a natural outlet approved by the city. Industrial cooling water, or unpolluted process waters, may be discharged, on approval of the city, to a storm sewer or natural outlet; provided, that all state, and federal, laws and regulations are met.
(E) No wastewater generated by a development located in the 100-year floodplain shall be transported, or treated, by city-owned facilities, except that service may be provided to:
(1) Areas of existing development in a floodplain;
(2) Commercial, or public, facilities which, by nature, must be located in a floodplain;
(3) Areas of projected growth if an environmental information document demonstrates that the proposed development will be consistent with the floodplain management criteria for flood-prone areas (44 C.F.R. § 60.3) of the Federal Emergency Management Agency (FEMA), and will have no significant impacts on natural functions, and values, of the floodplain; or
(4) An area of projected growth if an environmental impact statement demonstrates that there is no practicable alternative to such growth, that such growth will be consistent with the floodplain management criteria for floodprone areas (44 C.F.R. § 60.3) of FEMA, and that the benefits of such growth outweigh its environmental costs.
(F) No person shall discharge, or cause to be discharged, any of the following described water, or wastes, to any public sanitary sewer:
(1) Raw sewage not first treated through an interceptor tank;
(2) Explosive, or inflammable, liquids and gases, or any liquid or vapor having a temperature higher than 150°F;
(3) Any water, or waste, which contains more than 100 parts per million by eight, of fat, oil or grease, oil and sludge from service stations, garages, repair shops, machine shops, cleaning establishments or other industries, or establishments;
(4) Any gasoline, benzene, naphtha, fuel oil, or other flammable, or explosive, liquid, solid, gas, petroleum, coal tar, vegetable and mineral oils and products, and their derivatives and wastes, except sewage, as defined in § 51.03;
(5) Any ashes, cinders, sand, mud, straw, shavings, metal, glass, rags, feathers, tar, plastic, wood, paunch, stable or barn manure, offal from slaughterhouses, dead animals or other solid, or viscous substance capable of causing obstruction to the flow in sewers, or other interference with the proper operation of the sewage works;
(6) Any waters, or wastes, having a pH lower than 5.5, higher than 9.0, or having any other corrosive property capable of causing damage, or hazard, to structures, equipment, and personnel of the sewerage works;
(7) Any waters, or waste, containing a toxic, or poisonous, substance in sufficient quantity to injure, or interfere, with any sewerage treatment process, constitute a hazard to humans or animals, or create any hazard in the receiving waters of the sewage treatment facilities. Among substances that may be toxic to sewer systems, humans, and animals are the following: copper; chromium; cyanide; lead; zinc; arsenic; nickel; phenol detergents; wastes from nuclear fission; paints, or waste products from paint manufacturers, or acids; alkalis, or other corrosive liquids; gases; or substances of sufficient strength to damage sewers, manholes, pumping stations, or treatment plant units.
(a) Specifically, the following limitations on discharges to the city sewer will be observed. The following pollutant limits are established to protect against pass through and interference. No person shall discharge wastewater containing in excess of the following instantaneous maximum allowable discharge limits, except by permit from the Control Authority:
Pollutant Discharged
|
Amount of Discharge
|
Pollutant Discharged
|
Amount of Discharge
|
Arsenic | 0.1 mg/l |
Cadmium | 0.02 mg/l |
Chromium | 0.48 mg/l |
Copper | 0.23 mg/l |
Cyanide | 0.01 mg/l |
Lead | 0.1 mg/l |
Mercury | 0.0002 mg/l |
Nickel | 0.02 mg/l |
Silver | 0.024 mg/l |
Zinc | 0.1 mg/l |
(b) All concentrations for metallic substances are for “total” metal, unless indicated otherwise. The Control Authority may impose mass limitations in addition to, or in place of, the concentration-based limitations above.
(c) The city may revise, or modify, the local limits as required, or if deemed necessary to comply with the objectives presented in this subchapter, or to ensure compliance with federal, state, or local law.
(8) Any noxious, or malodorous, gas or substance capable of creating a public nuisance, or live steam, exhaust steam, or water having a temperature above 1,400F;
(9) Any liquids, gases, solids, or other wastewater which, either singly or by interaction with other wastes, are sufficient to create a public nuisance or a hazard to life, or to prevent entry into the sewers for maintenance or repair;
(10) Wastewater which imparts color which cannot be removed by the treatment process, such as, but not limited to, dye, wastes, and vegetable tanning solutions, which consequently imparts color to the treatment plant’s effluent, thereby violating the city’s NPDES permit;
(11) Wastewater containing any radioactive wastes or isotopes, except in compliance with applicable federal, or state, regulations, and approved by the Control Authority;
(12) Sludges, screenings, or other residues from the pretreatment of industrial wastes;
(13) Medical wastes, except as specifically authorized by the Control Authority; and
(14) Detergents, surface-active agents, or other substances which may cause excessive foaming in the POTW.
