General Industrial Discharge Permits
The Industrial Waste and Pollution Prevention (IWPP) section of the Metropolitan Council is the delegated Pretreatment Program authority for the seven-county Metro area. We regulate industrial wastewater discharges through a permitting system.
General Industrial Discharge Permits are issued to a specific industry group when it is determined that a standard permit is not applicable. If, within a specific industry group, operations and wastewater discharges are similar, and there are opportunities for best management practices to keep discharge volumes and strength charges consistent, then uniform requirements for the industry group may be appropriate.
IWPP currently administers general permits for six industry groups: dental clinics, healthcare facilities, microbreweries and brewpubs, sewer cleaning waste haulers, water treatment facilities, and zero-discharge industries (industries that have an EPA categorical process but do not discharge their categorical wastewater to the sanitary sewer system.)
