Industrial Waste

Industrial waste is any solid, liquid, or gaseous substance disposed of in a public sewer in the metropolitan area resulting from a business activity.

The Industrial Waste & Pollution Prevention (IWPP) Section of the Metropolitan Council Environmental Services Division regulates and monitors industrial discharges to the sewer system to ensure compliance with local and federal regulations. The IWPP Section also responds to sewer-related spills and community sewer problems. These functions protect MCES and community collection/treatment facilities, process efficiency, and operating personnel and the environment.

IWPP Section staff issue Industrial Discharge Permits to industrial users of the Metropolitan Disposal System (public sanitary sewers). Currently, approximately 900 permits are in effect. Permittees are required to conduct self-monitoring and submit reports to the IWPP Section on a routine basis. These reports are one means of determining compliance with the MCES Waste Discharge Rules.

Compliance determinations are also made through monitoring by the IWPP Section. The U.S. Environmental Protection Agency (EPA) requires MCES to inspect and monitor significant industrial users at least once per year. MCES' laboratory performs approximately 22,000 analyses per year for industrial monitoring conducted by the IWPP Section at about 400 industrial facilities.
