On Friday, Susan Hedman, U.S. Environmental Protection Agency Region 5 Administrator, gathered with Representative Rick Nolan (D-Minn) and Duluth Mayor Don Ness to announce the completion of the Chambers Grove Park habitat restoration project. The area is part of the St. Louis River Area of Concern and its restoration was partially funded by the Great Lakes Restoration Initiative. In 1987, there were 43 Areas of Concern (AOC) identified around the Great Lakes–primarily rivers and harbors with contaminated sediment and other severe habitat degradation. Since they were first designated in 1987, four United States AOCs and three Canadian AOCs have been delisted. The Chambers Grove Park celebration in Duluth puts the St. Louis River AOC one step closer to being delisted.
