This project will provide a protocol for prioritizing sites in the St. Louis Area of Concern (AOC ) for restoration based on site-specific bioavailability considerations. Despite large data collection efforts focused on sediment chemistry, the extent to which sediment with moderate levels of contamination is available for uptake into biota and therefore contributing to Beneficial Use Impairments (BUI)s is still largely unknown.
This project will provide technical, planning and engineering assistance to the MPCA for the development and implementation of the St. Louis River Remedial Action Plan (RAP). USACE and USEPA in partnership with the MPCA will administer work plans to complete a sediment assessment for Minnesota areas within Superior Bay, St. Louis Bay, Lower St. Louis River and the Upper St. Louis River, encompassing approximately 5,349 acres of the St. Louis River and Estuary.
Our program will protect, in perpetuity, native prairie tracts in western Minnesota. Fee title tracts will be the top priority for the funding. Funding will be used for the purchase of habitat easements if the funding cannot be used entirely on fee title tracts. The funding will purchase approximately 525 acres of native prairie in fee title, 1,583 acres of habitat easements, or a combination of the two.
