South Park Marina cleanup site, Seattle

Cleanup work is moving forward at the South Park Marina site next to the South Park Bridge in Seattle's South Park neighborhood.

There are three potentially liable persons for the South Park Marina cleanup site: South Park Marina Limited Partnership, the Port of Seattle, and the City of Seattle. These potentially liable persons are working on cleanup under a legal agreement with Ecology.

Twp documents are available for public comment:

• Remedial Investigation Report: Describes contaminants and where they are at the site. The report is in three documents: the main remedial investigation report, the tables and figures, and the appendices.
• Agreed Order Amendment: This extends the current legal agreement that requires the potentially liable persons to continue cleanup work by preparing a feasibility study that compares cleanup options, and by drafting a cleanup action plan, describing Ecology’s selected cleanup option.

The site is on the Duwamish River in an area of the LDW Superfund Site called the Upper Reach. The site has been used for residences and a variety of commercial uses since 1918. Since the 1960s, the site has been primarily used for marina operations. The historical uses of the site, along with a neighboring drycleaner, likely contributed to the contamination found here.
