Description Ecology invites you to review a cleanup action plan and associated documents for the cleanup of remaining contamination at the Gas Works Park site in Seattle. The plan calls for removing and capping shoreline soil, treating shoreline groundwater, dredging sediment, capping sediment, monitoring, and administrative site use controls. The plan is part of a legal agreement between Ecology, the City of Seattle (City), and Puget Sound Energy (PSE). The following documents are available for review: Cleanup Action Plan: describes Ecology’s selected cleanup action to address remaining contamination; Consent Decree (legal agreement): requires the City and PSE to develop detailed design documents and construct the cleanup action described in the cleanup action plan; State Environmental Policy Act-Determination of Non-Significance: Ecology determination that the cleanup action is not likely to have a significant adverse environmental impact.
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.
