   (B)   Discharges prohibited by division (A) of this section include, but are not limited to, materials which exert or cause concentrations of:
      (1)   Inert suspended solids greater than 250 mg/l including but not limited to:
         (a)   Fuller’s earth;
         (b)   Lime slurries; and
         (c)   Lime residues;
      (2)   Dissolved solids greater than 1,000 mg/l including but not limited to:

      (3)   Excessive discoloration including but not limited to:
         (a)   Dye wastes;

   (C)   No person may discharge into public sewers any substance that may be reasonably expected to:
      (1)   Deposit grease or oil in the sewer lines in such a manner as to clog the sewers;
      (2)   Overload skimming and grease handling equipment;
      (3)   Pass to the receiving waters without being effectively treated by normal wastewater treatment processes due to the non-amenability of the substance to bacterial action; or
      (4)   Deleteriously affect the treatment processes due to excessive quantities.
   (D)   No person may discharge any substance into public sewers which:
      (1)   Is not amenable to treatment or reduction by the processes and facilities employed; or
      (2)   Is amenable to treatment only to such a degree that the treatment plant effluent cannot meet the requirements of other agencies having jurisdiction over discharge to the receiving waters.
   (E)   The approving authority shall regulate the flow and concentration of slugs when they may:
      (1)   Impair the treatment process;
      (2)   Cause damage to collection facilities;
      (3)   Incur treatment costs exceeding those tor normal wastewater; or
      (4)   Render the effluent unfit for stream disposal or industrial use.
   (F)   No person may discharge into public sewers solid or viscous substances which may violate division (A) of this section if present in sufficient quantity or size, including, but not limited to:
