Standard Industrial Discharge Permits
Industrial users discharging wastewater into public sewers shall apply for an industrial discharge permit, unless Metropolitan Council Environmental Services (MCES) determines that the wastewater has an insignificant impact on public sewers. No industrial user requiring a permit shall discharge into public sewers until the industrial user has been issued a permit. All affected industrial users shall complete and file with MCES an Industrial Discharge Permit Application at least 90 calendar days prior to initiation of industrial waste discharge.

General Industrial Discharge Permits
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. MCES currently administers general permits for microbreweries and brewpubs, water treatment facilities, and zero-discharge industries - industries that have an EPA categorical process but do not discharge their process wastewater to the sanitary sewer system.

Liquid Waste Hauler Permits
Liquid waste haulers that want to use the Metropolitan Disposal System to discharge hauled domestic septage, commercial, and industrial wastes must obtain an MCES Liquid Waste Hauler Permit. The discharge of hauled waste into the system is only allowed at designated disposal sites. Haulers shall complete and submit an MCES Liquid Waste Hauler Permit Application along with the first year's permit fee (see Rates and Fees). Septage haulers who apply for an MCES Liquid Waste Hauler Permit must first obtain a Subsurface Treatment System (SSTS) license from the Minnesota Pollution Control Agency.
