SEATTLE -- King County this week will begin dredging about 70,000 cubic yards of contaminated sediment from the Lower Duwamish Waterway at the seven-acre Duwamish/Diagonal combined sewer overflow and storm drain north of Kellogg Island.
The county negotiated a $2.97 million contract with Delta, B.C.-based Miller Contracting Inc., which hired Chico, Calif.-based J.E. McAmis Industries as a subcontractor for dredging fill work, said Jeff Stern, of the county's wastewater treatment program. The county hired Rabanco on a roughly $3.2 million contract for sediment handling and disposal at a solid-waste landfill in eastern Washington, Stern said.
Duwamish/Diagonal is the first major early-action cleanup planned for the Lower Duwamish Waterway, which the United States Environmental Protection Agency added to the national Superfund list in 2001.
