FY18 St. Louis River AOC Slip 3 and Slip C Remedial Cap

The scope of work requires the contractor to provide all work, materials, equipment, labor, supervision, management, and administration to construct a remedial cap in two slips in the Duluth-Superior harbor. Both of these slips have areas with sediment concentrations for contaminants of concern above the respective clean up levels.

Slip 3 construction involves a limited amount of sediment leveling to reduce grade changes as well as dredging a 900 square foot area outside of the capping footprint and placing material in the deep portions of the capping area. Leveling activities will be followed by construction of a subaqueous cap over approximately 0.88 acres in the slip.

Slip C construction involves construction of a subaqueous cap over approximately 6 acres of the slip where sediment concentrations for contaminants of concern are above the respective clean up levels.
