(A) If any waters or wastes are discharged, or are proposed to be discharged, to the public sewers, which contain substances or possess the characteristics enumerated in the preceding sections of this subchapter, and which in the judgment of the Director or the local, State, and Federal agencies having jurisdiction, may have a deleterious effect upon the wastewater treatment processes, equipment, or receiving waters, or which otherwise create a hazard to life or constitute a public nuisance, the Director 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 rates of discharge; and
(4) Require payment to cover the added cost of handling and treating the wastes not covered by existing taxes or sewer user charges.
(B) In forming an opinion as to the acceptability of wastes, the Director 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 wastewater treatment process, capacity of the wastewater treatment facility, degree of treatability of wastes in the wastewater treatment facility, and other pertinent factors. Any waters or wastes having a BOD5 concentration greater than 250 mg/l or a suspended solids concentration greater than 250 mg/l or an average daily flow greater than 2% of the average total waste flow of the City shall be subject to the review of the Director.
(C) If the Director 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 Director, and the local, State, and Federal agencies having jurisdiction and subject to the requirements of all applicable codes, resolutions, and laws. See § 51.132.
(D) In the event of an accidental spill or unavoidable loss to the drains of any deleterious materials, the owner shall promptly notify the Director of the nature of the spill, the quantity, and time of occurrence.
