1. If any waters or wastes are discharged, or are proposed to be discharged into the public sewers, which waters contain the substances or possess the characteristics enumerated in Section 13.07.100, and which in the judgment of the director, 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 director may:

            a. Reject the wastes;

            b. Require Pretreatment to an acceptable condition for discharge into the public sewers.  To this end, the director may require pretreatment to (A) reduce the biochemical oxygen demand to three hundred parts per million by  weight, or (B) reduce the suspended solids to three hundred fifty parts per million by weight;

            c. Require control over the quantities and rates of discharge; and/or

            d. Require payment to cover the added cost of handling and treating the wastes not covered by existing taxes or sewer charges under the provisions of this chapter.

    2. 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 written approval of the director and subject to the requirements of all applicable codes, ordinances and laws.  The director may require a compliance schedule for the design, construction and installation of equipment for such pretreatment works.  No construction shall commence on such pretreatment facilities until the written approval of the director is obtained.  The costs of all pretreatment facilities shall be paid by the  person contributing the wastes.  (Ord. 83/T-2039; S-39108, 1979).
