ST. LOUIS RIVER AREA OF CONCERN UPDATES: 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 St. Louis River was designated as one of the 31 Areas of Concern (AOC) on the Great Lakes due to significant historical issues with pollution and degraded habitat.

For decades the Alliance has been working on projects with state, tribal, and federal agencies in order to delist the St. Louis River as an Area of Concern by 2025.

ST. LOUIS RIVER AREA OF CONCERN UPDATES: The remedial construction in the Azcon/DSPA Slip started this week! The activities at the site will include dredging and landfill disposal of approximately 700 cubic yards of contaminated sediments, followed by capping and armoring 2.2 acres of the slip. The remedial cap will be constructed with clean material beneficially dredged from the Duluth Navigational Channel. Construction is anticipated to continue throughout the month of October, and be completed by early November depending on weather.

The U.S. Army Corps of Engineers will remove more than 130,000 cubic yards of material, including contaminated sediment and debris, from Howards Bay in Superior, Wisconsin beginning this fall with most dredging activities finishing by November 2021.

"Cleanup of sediment at Howards Bay is a necessary action to remove beneficial use impairments and to eventually delist the St. Louis River Area of Concern."

Minnesota Pollution Control Agency announced cleanup options for the Scanlon and Thomson reservoir sites in the St. Louis River estuary. The public is encouraged to review and comment on the potential cleanup alternatives. The MPCA will consider all public comments, along with stakeholder input, in selecting the final cleanup remedy. Please submit written comments by 4:30 p.m. on August 31, 2020.
