The above limits apply at the point where the wastewater is discharged to the POTW (end of the pipe). All concentrations for metallic substances are for "total" metal unless indicated otherwise. The Pretreatment Coordinator 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 limit or applicable pretreatment standard shall apply.
