(A) In cases where, and in the opinion of the approving authority, the character or the wastewater from any manufacturing or industrial plant building or other premises is such that it will damage the system or cannot be treated satisfactorily in the system, the approving authority shall have the right to require such user to dispose of such waste otherwise and prevent it from entering the city system.
(B) No person shall discharge any unpolluted industrial water to the sanitary sewer system without the approval of the approving authority.
(C) Except in quantities or concentrations or with provisions as stipulated herein, it shall be unlawful for any person, corporation, or individual to discharge waters or wastes to the sanitary sewer containing:
(1) Free or emulsified oil and grease exceeding on analysis an average of 100 parts per million (834 pounds per million gallons) of either, both, or combinations of free or emulsified oil and grease if, in the opinion of the approving authority, it appears probable that such wastes:
(a) Can deposit grease or oil in the sewer line in such manner to clog the sewers.
(b) Are not amenable to bacterial action and will therefore pass to the receiving waters without being affected by normal wastewater treatment processes.
(c) Can have deleterious effects on the treatment process.
