(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 or in any area under the jurisdiction of said City, any human or animal excrement, garbage or other objectionable waste.
(B) It shall be unlawful to discharge to any natural outlet within the City, or in any area under the jurisdiction of said City, any sewage or other polluted waters, except where suitable treatment has been provided in accordance with subsequent provisions of this chapter.
(C) Except as hereinafter provided, it shall be unlawful to construct or maintain any privy, privy vault, septic tank, cesspool or other facility intended or used for the disposal of sewage.
(D) 1. No person shall discharge or cause to be discharged any stormwater, surface water, groundwater, roof runoff, subsurface drainage, uncontaminated cooling water, or unpolluted industrial process waters to any sanitary sewer.
2. Stormwater and all other unpolluted drainage shall be discharged to such sewers as are specifically designated as combined sewers or storm sewers, or to a natural outlet approved by the approving authority. Industrial cooling water or unpolluted process waters may be discharged, on approval of the approving authority, to a storm sewer, combined sewer or natural outlet.
(E) No person shall discharge or cause to be discharged any of the following described waters or wastes to any public sewers:
1. Any gasoline, benzene, naphtha, fuel oil or other flammable or explosive liquid, solid or gas.
2. Any waters or wastes containing toxic or poisonous solids, liquids or gases in sufficient quantity, either singly or by interaction with other wastes, to injure or interfere with any sewage treatment process, constitute a hazard to humans or animals, create a public nuisance, or create any hazard in the receiving waters of the sewage treatment plant.
3. Any waters or wastes having a pH lower than 5.5, or having any other corrosive property capable of causing damage or hazard to structures, equipment, and personnel of the sewage works.
4. 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 sewage works such as, but not limited to, ashes, cinders, sand, mud, straw, shavings, metal, glass, rags, feathers, tar, plastics, wood, unground garbage, whole blood, paunch manure, hair and fleshings, entrails and paper dishes, cups, milk containers, etc., either whole or ground by garbage grinders.
5. Waters or wastes containing substances which are not amenable to treatment or reduction by the sewage treatment processes employed, or are amenable to treatment only to such degree that the sewage treatment plant effluent cannot meet the requirements of agencies having jurisdiction over discharge to the receiving waters.
(F) No person shall discharge or cause to be discharged the following described substances, materials, waters or wastes if it appears likely in the opinion of the approving authority that such wastes can harm either the sewers, sewage treatment process or equipment; have an adverse effect on the receiving stream; or can otherwise endanger life, limb, public property or constitute a nuisance. In forming his opinion as to the acceptability of these wastes, the approving authority will give consideration as to such factors as the quantities of subject wastes in relation to flows and velocities in the sewers, materials of construction of the sewers, nature of the sewage treatment process, capacity of the sewage treatment plant, degree of treatability of wastes in the sewage treatment plant, and maximum limits established by regulatory agencies. The substances prohibited are:
1. Any liquid or vapor having a temperature higher than one hundred fifty degrees Fahrenheit (150°F) (65°C).
2. Any waters or wastes containing toxic or poisonous materials; or oils, whether emulsified or not, in excess of one hundred milligrams per liter (100 mg/L) or containing substances which may solidify or become viscous at temperatures between thirty two degrees Fahrenheit (32°F) (0°C) and one hundred fifty degrees Fahrenheit (150°F) (65°C).
3. Any garbage that has not been properly shredded. The installation and operation of any garbage grinder equipped with a motor of three-fourths (3/4) horsepower (0.76 hp metric) or greater shall be subject to the review and approval of the approving authority.
4. Any waters or wastes containing strong acid, iron pickling wastes, or concentrated plating solutions whether neutralized or not.
5. Any waters or wastes containing iron, chromium, copper, zinc, or similar objectionable to toxic substances; or wastes exerting an excessive chlorine requirement, to such degree that any such material received in the composite sewage at the sewage treatment works exceeds the limits established by the approving authority for such materials.
6. Any waters or wastes containing phenols or other taste or odor-producing substances, in such concentrations exceeding limits which may be established by the approving authority as necessary, after treatment of the composite sewage, to meet the requirements of the State, Federal or other public agencies of jurisdiction for such discharge to the receiving waters.
7. Any radioactive wastes or isotopes of such half-life or concentration as may exceed limits established by the approving authority in compliance with applicable State or Federal regulations.
8. Any waters or wastes having a pH in excess of 9.5.
9. Any mercury or any of its compounds in excess of 0.0005 milligrams per liter as Hg at any time except as permitted by the approving authority in compliance with applicable State and Federal regulations.
10. Any cyanide in excess of 0.025 milligrams per liter at any time except as permitted by the approving authority in compliance with applicable State and Federal regulations.
11. Materials which exert or cause:
(a) Unusual concentrations of inert suspended solids (such as, but not limited to, fullers earth, lime slurries, and lime residues) or of dissolved solids (such as, but not limited to, sodium chloride and sodium sulfate);
(b) Excessive discoloration (such as, but not limited to, dye wastes and vegetable tanning solutions);
(c) Unusual BOD, chemical oxygen demand or chlorine requirements in such quantities as to constitute a significant load on the sewage treatment works;
(d) Unusual volume of flow or concentrations of wastes constituting "slugs" as defined herein. (Ord. 76-8, 10-25-1976)
