§ 150-19. Pretreatment of specific pollutants.

The admission into the public sewers of any waters or wastes containing five-day BOD greater than 250 parts per million by weight (mg/l) or containing more than 350 parts per million by weight (mg/l) of suspended solids or containing any quantity of substances having the characteristics described in § 150-17 or having any average daily flow greater than 2% of the average total daily sewage flow of the City shall be subject to review and approval of the Director of Utilities. Additionally, the Director of Utilities reserves the right to alternatively impose mass pollutant discharge limitation on one or more of the regulated pollutants on any user that he deems appropriate. Where necessary in the opinion of the City, the owner shall provide, at his expense, such treatment or pretreatment as may be necessary to reduce the five-day BOD to 250 parts per million by weight (mg/l) or to reduce objectionable characteristics or constituents to within the maximum limits provided for in § 150-17 or control the quantities and rates of discharge of such waters or wastes. Plans, specifications and other pertinent information relating to proposed treatment or pretreatment facilities shall be prepared and submitted by a registered professional engineer for the approval of the Director of Utilities, and no construction of such facilities shall be commenced until said approvals are obtained in writing.
