§ 51.053 DISCHARGES WHICH MAY HARM THE SEWERS OR TREATMENT EQUIPMENT.
   (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 Village Engineer that the wastes can harm either the sewers sewage treatment process or equipment; have an adverse effect on the receiving stream; or can otherwise endanger life, public property, or constitute a nuisance. In forming his 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 having a temperature higher than 150 degrees Fahrenheit.
      (2)   Any waters or wastes containing toxic or poisonous material 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 and 150 degrees Fahrenheit.
      (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 hp metric) or greater shall be subject to the review and approval of the Village Engineer.
      (4)   Any waters or wastes containing strong acid, iron pickling wastes, or concentrated plating solution 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 the degree that any material received in the composite sewage at the sewage treatment works exceeds the limits established by the Village Engineer for the 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 Engineer as necessary after treatment of the composite sewage, to meet the requirements of the State, Federal, or other public agencies of jurisdiction for the discharge to the receiving waters.
      (7)   Any radioactive wastes or isotopes of half-life or concentration as may exceed limits established by the Village Engineer in compliance with applicable State or Federal regulations.
      (8)   Any wastes or waters having a pH in excess of 9.5.
      (9)   Any chemical constituent in excess of the following levels except as permitted by the Village Engineer and in compliance with applicable State and Federal regulations.

      (10)   Materials which exert or cause:
         (a)   Unusual concentrations of inert suspended solids (including, but not limited to, fuller's earth, lime slurries, and lime residues) or of dissolved solids (including, but not limited to, sodium chloride and sodium sulfate);
         (b)   Excessive discoloration (including, 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 herein.
      (11)   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 the degree that the sewage treatment plant effluent cannot meet the requirements of agencies having jurisdiction over discharge to the receiving waters.
   (B)   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 Chapter and which are in violation of the standards for pretreatment provided in 40 CFR 403, June 26,1979, and any amendments thereto, and which in the judgment of the Village Engineer 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 Engineer may:
      (1)   Reject the wastes;
      (2)   Require pretreatment to an acceptable condition for discharge to the public sewers;
      (3)   Require control over the quantities and rate of discharge; and/or
      (4)   Require payment to cover the added costs of handling and treating the wastes not covered by existing taxes or charges under the provisions of § 51.058 of this Chapter.
   (C)   If the Village Engineer permits the pretreatment or waste flows, the design and installation of the plants and equipment shall be subject to the review and approval of the Village Engineer and subject to the requirements of all applicable codes, ordinances and laws.
