(A) 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 Superintendent, that such wastes can enter the sewer’s 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 or her opinion as to the acceptability of these wastes, the Village Engineer will give consideration 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 150°F or 65°C.
(2) Any waters or wastes containing toxic or poisonous materials or oils, whether emulsified or not, in excess of 100 mg/l or containing substances which may solidify or become viscous at temperatures between 32°F and 150°F (0°C and 65°C).
(3) Any garbage that has not been properly shredded. The installation and operation of any garbage grinder equipped with a me of three-fourths horsepower (0.76 HP metric) or greater shall be subject to the review and approval of the Superintendent.
(4) Any waters or wastes containing strong acid, iron pickling, 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 such degree that any such material received in the composite sewage at the sewage treatment works exceeds the limits established by the Village Board 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 Village Board 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 Village Board 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 mg/l as Hg at any time except as permitted by the Village Board in compliance with applicable state and federal regulations.
(10) Any cyanide in excess of 0.025 mg/l at any time, except as permitted by the Village Board 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; and/or
(d) Unusual volume of flow or concentrations of wastes constituting slugs as defined herein.
(12) Waters or wastes containing substances which are not amenable 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 agency having jurisdiction over discharge to the receiving waters.
(B) (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 this division (B), and/or which are in violation of the standards for pre-treatment provided in Chapter 1, EPA Rules and Regulations, subchapter I, 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 Board, may have a deleterious effect upon the sewage works, processes, equipment, or receiving waters, or which otherwise create a hazard to life or constitute a public nuisance, the Village Board 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; and/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 this subchapter providing for the combination of the existing waterworks system and the sanitary sewerage system of the village into a combined single system.
(2) If the Village Board permits 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 Board and subject to the requirements of all applicable codes, ordinances, and laws.
