Local limits shall be established by the control authority by ordinance. The local limits shall be on a uniform concentration limit basis or selected reductions for specific industrial users. The pollutant limits established by the local limits are established to protect against pass-through and interference. No person shall discharge wastewater containing in excess of instantaneous maximum allowable discharge limits as established by authority ordinance. The local limits as established by the control authority ordinance shall apply at the point where the wastewater is discharged to the POTW. All concentrations for metallic substances are for “total” metal unless indicated otherwise. The control authority may impose mass limitations in addition to or in place of the concentration-based limitations.
