Lower Minnesota River Dissolved Oxygen Total Maximum Daily Load Report 2019 Modification

The Minnesota Pollution Control Agency (MPCA) is making adjustments to stormwater wasteload allocations (WLAs) to account for new regulated-Municipal Separate Storm Sewer Systems (MS4s). There are six new regulated-MS4s within the TMDL project area, Blue Earth County (Permit #MS400276), Eagle Lake City (Permit #MS400284), Mankato Township (Permit #MS400297), Skyline City (Permit #MS400292), South Bend Township (Permit #MS400299), and Minnesota State University Mankato (Permit #MS400279) (Table 1; Table 2). There is also a new 2010 Census Defined Urbanized Area in this TMDL project area, so the Minnesota Department of Transportation (MnDOT) Outstate District (Permit #MS400180) is also a new regulated MS4 in this area.
