1. No nonresidential user shall discharge wastewater containing restricted substances into the POTW in excess of limitations specified in its wastewater discharge permit or adopted, by resolution, by the city. The Public Works Director or other designee shall publish and revise, from time to time, standards for specific restricted substances. These standards shall be developed in accordance with 40 C.F.R. Section 403.5 and shall implement the objectives of this chapter. Standards published in accordance with this section will be deemed pretreatment standards for the purposes of Section 307(d) of the Act.
2. The Public Works Director or other designee may impose mass limitations in addition to (or in place of) the concentration-based limitations above. Where a user is subject to a categorical pretreatment standard and a local limit for a given pollutant, the more stringent or applicable pretreatment standard shall apply.
C. BMP - The Public Works Director or other designee may develop best management practices (BMPs), by ordinance or in individual wastewater discharge permits, to implement local limits and the requirements of § 13.16.015. Such BMP's shall be considered local limits and pretreatment standards.
