(a) No person shall discharge or cause to be discharged any of the following described waters or wastes to any public sewer:
(1) Any toxic or hazardous wastes as defined in Section 307(a) of the Clean Water Act, any industrial wastes which have not received the proper pretreatment as per Section 307(b) of the Clean Water Act, or any water or wastes which would result in a violation of the Village’s NPDES permit.
(2) Any gasoline, benzene, naphtha, fuel oil or other flammable or explosive liquid, solid or gas is prohibited.
(3) 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 plant.
(4) Any 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.
(5) 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, containers, etc. either whole or ground by garbage grinders.
(6) Any waters or wastes containing substances which are not amenable to treatment or regulation 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.
(b) No person shall discharge or cause to be discharged the following described substances, if it appears likely in the opinion of the Manager that such wastes can harm either the sewers, sewage treatment process, or equipment; can have an adverse effect on the receiving stream; or can otherwise endanger life, limb, public property, or constitute a nuisance. In forming an opinion as to the acceptability of these wastes, the Manager shall give consideration to such factors as the quantities of wastes in relation to flows and velocities in the sewers, materials of construction of the sewers, nature of the sewers, materials of construction of the sewage treatment plant, degree of treatability of wastes in the sewage treatment plant, and maximum limits established by regulatory agencies. The harmful substances are:
(1) Any liquid or vapor having a temperature of higher than 150 degrees Fahrenheit.
(2) Any waters or wastes containing oils, whether emulsified or not, in excess of 100 mg/l or containing substances which may solidify or become viscous at temperatures between thirty-two and 150 degrees Fahrenheit.
(3) Any waters or wastes containing iron, chromium, copper, zinc or similar objectionable or toxic substances; or wastes exerting an excessive chlorine requirement, to such degree that any such material received in limits established for such materials.
(4) Any garbage that has not been properly shredded.
(5) Any waters or wastes containing phenols or other taste or odor- producing substances in concentrations exceeding the limits of the State, Federal or other public agencies having jurisdiction for such discharge to the receiving waters.
(6) Any radioactive wastes or isotopes of such half-life or concentration as may exceed limits established by State or Federal regulations.
(7) Any wastes or waters having a pH in excess of 9.5.
(8) Any mercury or cyanide except as permitted by the Manager in compliance with applicable State and Federal regulations.
(9) Materials which exert or cause:
A. Unusual concentrations of inert suspended solids (such as, but not limited to, 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.
(c) No connections shall be made to the sanitary sewer system which convey storm water, surface water, ground water, or roof runoff from any buildings, structure, yard or paved surface.
(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 Manager.
