(A) 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 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 a 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, and the like, either whole or ground by garbage grinders.
(B) 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 village and MSDGC that these 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 an opinion as to the acceptability of these wastes, the village and MSDGC representatives will give consideration to all 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 150°F. (65°C.).
(2) Any waters or wastes containing toxic or poisonous materials; or oils, whether emulsified or not, in excess of 100 milligrams per liter or containing substances which may solidify or become viscous at temperatures between 32° and 150°F. (0° and 65°C.).
(3) Any garbage that has not been properly shredded. The installation and operation of any garbage grinder equipped with a motor of 3/4-horsepower (0.76 horsepower metric) or greater shall be subject to the review and approval of the village.
(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 or toxic substances; or wastes exerting an excessive chlorine requirement, to a degree that any material received in the composite sewage at the sewage treatment works exceeds the limits established by the village and MSDGC for such materials.
(6) Any waters or wastes containing phenols or other taste- or odor-producing substances, in concentrations exceeding limits which may be established by the village and MSDGC as necessary after treatment of the composite sewage, to meet the requirements of the state, federal, or other public agencies of jurisdiction for that discharge to the receiving waters.
(7) Any radioactive wastes or isotopes of a half-life or concentration as may exceed limits established by the village and MSDGC 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 0.05 milligrams per liter as Hg (hydrargyrum) at any time except as permitted by the village and MSDGC 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 village and MSDGC 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 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 in § 51.003
(12) 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 a degree that the sewage treatment plant effluent cannot meet the requirements of agencies having jurisdiction over discharge to the receiving waters.
(C) (1) If any waters or wastes are discharged or are proposed to be discharged to the public sewers, which waters contain the substances or possess the characteristics enumerated in division (B) above or which are in violation of the standards for pretreatment provided in Chapter 1, EPA Rules and Regulations, subchapter D, Water Programs Part 128 - Pretreatment Standards, Federal Register Volume 38, No. 215, Thursday, November 8, 1973 and any amendments thereto, and which in the judgment of the village or MSDGC may have a deleterious effect upon the sewerage works, processes, equipment, or receiving waters, or which otherwise create a hazard to life or constitute a public nuisance, the village or MSDGC may:
(a) Reject the wastes;
(b) Require pretreatment to an acceptable condition for discharge to the public sewers;
(c) Require control over the quantities and rates of discharge; or
(d) Require payment to cover the added costs of handling and treating the wastes not covered by existing taxes or sewer charges, under the provisions of § 51.061.
(2) If the village and MSDGC permit the pretreatment or equalization of waste flows, the design and installation of the plants and equipment shall be subject to the review and approval of the village and MSDGC, and subject to the requirements of all applicable codes, ordinances, and laws.
(D) It is recognized that the village and the MWRD have entered into a certain Sewer Service Agreement dated May 18, 1978, as amended, for areas within the village but outside of the corporate limits of the MWRD, and that compliance with all the provisions of such Sewer Service Agreement as amended and the MWRD's Sewage and Waste Control Ordinance incorporated therein is hereby made an operative provision of this section fully as if set forth at length herein.
