AZCON Slip GLRI clean-up complete

The St. Louis River Area of Concern (AOC) is one step closer to delisting following completion of a contaminated sediment clean-up project at AZCON/Duluth Seaway Port Authority’s Slip November 12. The Great Lakes Restoration Initiative (GLRI) and Minnesota Pollution Control Agency (MPCA)-funded project removed 850 cubic yards of contaminated sediment and capped an additional 55,000 cubic yards using a cap comprised of clean dredge material from the federal navigation channel and armoring stone to protect it from erosion. “By beneficially reusing the dredged material from the navigation channel, the team was able to achieve remedial objectives, limit waste generation and decrease the environmental impact,” said Amanda Meyer, project manager, U.S. Army Corps of Engineers, Detroit District.
