South Park Marina Cleanup Plan Moves Ahead

The owner of a marina and boatyard along the Duwamish Waterway in Seattle, WA, and two local governments have negotiated an agreement with the Washington Department of Ecology to test the site for soil and groundwater contamination, a step toward planning a future cleanup.

The Washington Department of Ecology invites the public to review and comment on the agreement, called an agreed order, through January 23, 2018. The order and participation plan cover the 4-acre South Park Marina at 8604 Dallas Ave. S.

Under the order, the three parties will investigate contamination at the site.

Ecology negotiated the order with South Park Marina Limited Partnership, the City of Seattle and the Port of Seattle.

Part of the Lower Duwamish Waterway cleanup

The cleanup will contribute to a larger effort to control sources of contamination in Lower Duwamish Waterway sediments.

Ecology and the U.S. Environmental Protection Agency jointly manage the Lower Duwamish Waterway cleanup, along approximately 5 miles of waterway upstream from Harbor Island.

Ecology oversees a variety of efforts to control sources of pollution that could re-contaminate waterway sediments after cleanup. This source control work includes cleanups at contaminated sites along or near the Duwamish.

According to an official announcement, the agreed order for South Park Marina would add the site to a list that includes 21 other formal Ecology cleanup sites along or near the Duwamish Waterway as well as five sites managed by EPA under the federal Superfund program.
