CSO Annual Reports

The Minnesota Pollution Control Agency (MPCA) has issued joint National Pollutant Discharge Elimination System (NPDES) Combined Sewer Overflow (CSO) permits to the City of Minneapolis and Metropolitan Council Environmental Services (MCES) since 1985.

This permit regulates CSOs by defining certain conditions that should be followed if an overflow event from the sanitary system occurs, including: 

A separate inter-agency agreement between the City and MCES details each permittee’s responsibilities with respect to operation of the collection system, and notification in the event of a CSO from the sanitary sewer system.
Each year, the City of Minneapolis and MCES submit an Annual Report to the MPCA detailing all aspects of their respective CSO Programs.  Below are links to past City of Minneapolis Reports in PDF form
