(h) Waters or wastes containing substances which are not amenable to treatment or reduction by the wastewater treatment process employed, or are amenable to treatment only to such degree that the wastewater treatment plant effluent cannot meet the requirements of other agencies having jurisdiction over discharge to the receiving waters.

(i) Any water or wastes which, by interaction with other water or wastes in the public sewer system, release obnoxious gases, form suspended solids, which interfere with the collection system, or create a condition deleterious to structures and treatment processes.

SECTION 18 - 35. HANDLING OF MATERIALS ALLOWED LIMITED DISCHARGE.

(a) 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 Section 94 - 29, and which in the judgment of the Joint Powers Board, may have a deleterious effect upon the wastewater facilities, processes, equipment, or receiving waters or which otherwise create a hazard to life or constitute a public nuisance, the Joint Powers Board may:

(1) Reject the waste.

(2) Require pretreatment to an acceptable condition for discharge to the public sewers.

(3) Require control over the quantities and rates of discharge.

(4) Require payment to cover the added cost of handling and treating the wastes not covered by existing sewer charges.
