§ 98-91. Pretreatment of wastes.

Persons discharging industrial wastes into the sewerage system may be required to pretreat such wastes. Plans for all pretreatment facilities shall be approved by the city or the state environmental protection division prior to construction. At the time written plans are submitted for approval, written maintenance plans shall also be submitted and approved by the city. The facilities shall be allowed to operate only as long as they are maintained in accordance with the approved maintenance plans. Pretreatment requirements shall be determined on a case-by-case basis and shall include the following facilities as a minimum:

(1)

If plans are submitted for the neutralization of strong acid or alkaline wastes, the plans shall include the necessary instrumentation and controls to ensure compliance with the regulations of this section at all times.

(2)

Holding tanks or equalization basins shall be required ahead of the receiving manhole of the city sewerage system when deemed necessary by the city to prevent peak flows that exceed the capacity of the system or that result in operational problems.

(3)

All pretreatment facilities shall be operated and maintained continuously in satisfactory and effective operation by the owner at his expense.
