923.03 NONACCEPTABLE WASTEWATER AND INDUSTRIAL PRETREATMENT.
   (a)   The City shall make and enforce rules and regulations establishing the types and characteristics of sewage, industrial wastes, and other matters which shall be discharged into the sanitary sewerage system, the types and characteristics of sewage and industrial wastes admissible to the system only after pretreatment, requisites for pretreatment, and otherwise governing the discharge of sewage, industrial wastes, and other matters into the system in the interest of safety and efficient operation of the wastewater treatment plant. Applicable industrial pretreatment conditions and industrial pretreatment regulations, as promulgated under Section 307(b) of the Clean Water Act and included in 40 CFR Part 403, are hereby incorporated in this chapter and made a part hereof.
 
   (b)    An industry must, upon application for sewer service, present to the City a tabulation of the chemical analysis of the wastes to be discharged to sewerage system and the volume of such wastes, or if this is not available, the expected waste analysis based on similar processes now in operation. New industries or industries with significant increases in discharge volume or strength must submit information on wastewater characteristics and obtain prior approval from the City before discharging to the sanitary sewer system.
 
   (c)    In cases where the character of sewage or industrial waste from any manufacturing or industrial plant, building, or premises is such that it will damage the sewerage system or cannot be treated satisfactorily at the wastewater treatment plant, the City shall compel such users to dispose of such waste and prevent it from entering the sewerage system.
 
   (d)    In cases where the character of the sewage or industrial waste from any manufacturing or industrial plant, building, or premises is such that it imposes an unreasonable burden upon the sewage collection, pumping, or treatment works greater than that imposed by the average sewage entering the sewerage system, the City may: compel such manufacturing or industrial plant, building, or premises to pretreat such sewage in such manner as specified by the City before discharging it into the sewerage system; require flow control or equalization of such wastes so as to avoid any "slug" loads or excessive loads that may be harmful to the treatment works; or require payment of a surcharge on any excessive flows or loadings discharged to the treatment works to cover the additional costs of having capacity for and treating such wastes.
