Site Background

Boathouse Inc Renton Skyway cleanup site.
Boathouse Inc Renton Skyway cleanup site.

The Boathouse Inc. Renton Skyway site (Site) is a former retail store and dry cleaning facility (Ken's Skyway Cleaners) located in Seattle, King County, Washington. A dry cleaning facility (Ken’s Skyway Cleaners) was in operation at the Site from 1982-2002. Operations at this dry cleaning facility resulted in the release of hazardous chemicals to soil and groundwater.  The 0.48-acre property is located approximately 5,700 feet from the Duwamish River, and zoned for community business (CBSO) use.

Municipal groundwater wells for the Skyway Water District (approximately 9,890 users) and the City of Renton (approx. 62,100 users) are located within 2 miles of the Site. Solvent-impacted groundwater has been confirmed at the Site, but has not been confirmed to affect municipal groundwater supplies.

What Has Been Done At The Site?

1999

June 1999, the Site was reported to Washington State Department of Ecology due to a release. In July 1999, an investigation was completed.

2002

The Site joined the Voluntary Cleanup Program (VCP) in 2002 and placed on the list with ID number NW0926, and was terminated from the program in 2007 due to inactivity. 


2013
In August 23, 2013, a groundwater monitoring report showed that PCE (a chemical primary used for dry-cleaning fabrics and degreasing metals) and TCE were found in groundwater above state cleanup levels.

2015
Ecology conducted a Site Hazardous Assessment and added the Site to the H
azardous Sites List with a ranking of "3" moderate risk.

 

2019

In January 17, 2019, a Limited Phase II screening was conducted.  PCE, TCE and Vinyl Chloride (VC) were found above state cleanup level in groundwater. This report also documents the potential of the groundwater plume migrating to the south and under the adjacent southern property. 

 

2020

Ecology is beginning negations with the liable persons to clean up the Site.

 

State Cleanup Process

The Model Toxics Control Act (MTCA; Chapter 70.105D RCW) is Washington’s environmental cleanup law. It provides requirements for contaminated site cleanup and sets standards that protect human health and the environment. Ecology enacts the MTCA and oversees cleanups. The MTCA site cleanup process is completed in steps (see graphic to the left) over a variable timeline.
