LDWG and EPA are joining the Department of Ecology for their Community Office Hours at the Duwamish River Community Hub on Thursday, October 24, from 4:30 to 6:30 p.m. Stop by to talk with project staff and learn more about the cleanup of the Lower Duwamish Waterway. Hope to see you there!
Statement on the EPA’s Unilateral Administrative Order (UAO)
The City of Seattle, King County, and Boeing are pleased that on Thursday, July 18, the U.S. Environmental Protection Agency (EPA) signed a Unilateral Administrative Order (UAO), allowing cleanup construction to begin this fall on the Lower Duwamish Waterway Superfund Site.
What We’re Working On
The 100% Remedial Design for the upper reach portion of the Lower Duwamish Waterway is now available. The document is posted here (see Upper Reach Design AOC Amendment 4) and describes key elements for implementing the cleanup remedy for part of the Lower Duwamish Waterway (LDW) Superfund Site. Construction is anticipated to begin in the upper reach in late 2024.
What We’ve Accomplished
Completed Studies LDWG has completed multiple studies to help us better understand the contamination and ways to clean it up.
Early Action Areas LDWG is already making progress in its cleanup effort. We’ve completed cleanup at our five early action sites, which has lowered PCB contamination levels in sediments by over one half.
The Lower Duwamish Waterway Group (LDWG) is a public-private partnership committed to advancing the U.S. Environmental Protection Agency (EPA)-led sediment cleanup of the Lower Duwamish Waterway in Seattle, Washington. LDWG (pronounced “Ludwig”) includes The Boeing Company, the City of Seattle, and King County. Since EPA listed the Lower Duwamish Waterway as a Superfund site in 2001, LDWG has invested nearly $200 million in waterway studies and early action cleanups. LDWG continues to advance the cleanup design and is working to implement source control actions until the cleanup is complete.
