(a) The admission into the public sewers of any waters or wastes having:
(1) A 5-day biochemical oxygen demand greater than 300 parts per million by weight; and/or
(2) More than 300 parts per million by weight of suspended solids; and/or.
(4) An average daily flow greater than 25,000 gallons per day;
Shall be subject to the review arid approval of the Safety-Service Director and the Plant Manager of the wastewater treatment plant.
(b) The Safety-Service Director and the Plant Manager of the wastewater treatment plant shall have the right to reject any and all wastes which, in their opinion, may be harmful to or exceed capacities of the wastewater treatment system. Where necessary, in the opinion of the Safety-Service Director and the Plant Manager of the wastewater treatment plant, the owner shall provide at his expense such preliminary treatment as may be necessary to:
(1) Reduce the biochemical oxygen demand to 300 parts per million and the suspended solids to 300 parts per million by weight;
(3) Control the quantities and rates of discharge of such waters or wastes. Detailed plans, specifications, operating procedures, and any other pertinent information relating to proposed treatment facilities shall be submitted for the approval of the City Engineer, Safety-Service Director and the Plant Manager of the wastewater treatment plant. The review of such plans and operating procedures shall in no way relieve the User from the responsibility of modifying such facilities as necessary to produce a discharge acceptable to the City under provisions of this ordinance. No construction of such facilities shall be commenced until such approval is obtained in writing.
(c) The discharge of industrial wastes with concentrations exceeding the "normal strength" limitations may be permitted when, in the opinion of the Safety-Service Director and the Plant Manager of wastewater treatment plant, it is determined that such wastes can be satisfactorily treated without adverse effects to the collection and/or treatment systems. The industrial waste mentioned in this section must be a biologically degradable wastewater constituent capable of being removed by the existing wastewater treatment plant. Priority pollutants do not fall within this category.
The discharge of such wastes exceeding "normal strength" shall be subject to and require a surcharge to compensate the City for all costs associated with the collection, conveyance, treatment, and final disposal for all excess concentrations as provided for in Section 937.10.
(d) The discharge of industrial wastes with concentrations containing greater than the following limits require review and approval of the City Engineer and Plant Manager before discharge. This approval may be outlined ih the permit to discharge, or added as an addendum.
