Description The Washington State Department of Ecology (Ecology) is lead agency for Source Control in the Lower Duwamish Waterway (LDW) Superfund Site and the U.S. Environmental Protection Agency (EPA) is lead for sediment cleanup according to the 2014 cleanup plan called the Record of Decision (ROD). Since the early 2000’s, Ecology began identifying and controlling pollution sources using state regulatory authorities, reducing the likelihood of recontaminating sediments after the Superfund cleanup is completed. Now that EPA is approaching the start of sediment cleanup, Ecology is preparing our Source Control Sufficiency recommendations. This document explains ‘LDW Source Control,’ ‘LDW Source Control Sufficiency’, and the Sufficiency evaluation process.
The mission of the Department of Ecology is to protect, preserve, and enhance Washington’s environment. To help us meet that goal, please consider the environment before you print or request a copy.
