Part 1: Boat Tour of the Duwamish River
PLEASE NOTE: registration for dinner does NOT register you for the tour!
- What: Port of Seattle's "Duwamish River 101"
- Where: Bell Harbor Marina, Pier 66
- When: Sept. 28, 2011, Check-in 3:45 pm, Program 4:00 - 6:30 pm
- Partners: Environmental Protection Agency, Duwamish River Clean Up Coalition, Environmental Coalition of South Seattle (ECOSS), Seattle Marine Business Coalition
Description: Board a floating classroom and see the heart of the Duwamish industrial area representing 80 percent of Seattle’s industrial land and more than 80,000 jobs, with an annual payroll of $2.5 billion. The 5-mile-long Duwamish Waterway provides commerce and jobs, as well as critical fish and wildlife habitat and public shoreline use areas. Government, community and business efforts have combined to make the waterway flow cleaner into Elliott Bay. You’ll learn about marine industrial commerce, the legacy of past industrial activities, fish and wildlife habitat restoration, and Superfund cleanup plans.

"Lower Duwamish Waterway Sediment Cleanup"
Abstract
The Lower Duwamish Waterway (LDW) cleanup site is a 5.5 mile portion of the Duwamish River, which flows into north into Elliott Bay past Harbor Island. A wide variety of contaminants are present in sediments, including PCBs, PAHs, arsenic, dioxin, metals and phthalates. The site was listed on the National Priorities List in 2001 and the Washington Hazardous Sites List in 2002. The LDW is under a joint MTCA/CERCLA Agreed Order on Consent with EPA, Ecology and the Respondents: the Lower Duwamish Waterway Group (LDWG: the city of Seattle, the Boeing Company, the Port of Seattle, and King County). EPA and Ecology have established a constructive working relationship with LDWG. Ecology leads source control efforts in close coordination with local governments and supports EPA extensively on the Remedial Investigation/Feasibility Study (RI/FS). Source control efforts are expansive, requiring identification and management of contaminants in an urban drainage area encompassing 32 square miles.
The 2010 draft FS identified several alternatives ranging from No Further Action to extensive sediment removal and capping. The cost estimates for sediment cleanup range from $60 to >$800 million and require from 3 to 42 years of construction. EPA and Ecology will propose a remedy in early 2012 after consultation with EPA’s National Remedy Review Board and Contaminated Sediments Technical Advisory Group. Following public comment, the remedy will be selected in a Record of Decision using a comparative analysis that evaluates costs and benefits.
This presentation will provide an overview of the site and the remedial alternatives proposed in the FS, as well as a brief update on what has been accomplished to date.
