The Corps of Engineers’ Supplemental Environmental Assessment (EA) was held in 2013 to document the changes made since the federal Environmental Impact Statement (EIS) was published in July 2011.
Col. Daniel C. Koprowski, commander of the U.S. Army Corps of Engineers, St. Paul District, signed documents which updated the EA in September, 2013. Any documents receiving updates have also been updated here.
