Department of Ecology News Release - July 27, 2016
SEATTLE – The owners and operators of an industrial site in Seattle’s Georgetown neighborhood have signed an agreement with the Washington Department of Ecology to test soil and groundwater for contamination, a step toward planning an eventual cleanup.
Ecology invites the public to review and comment on an agreed order through Aug. 20, 2016.
The legal agreement covers studies of contamination and cleanup options and development of cleanup plans for the 3-acre site at 730 S. Myrtle St., 625 feet east of the Lower Duwamish Waterway.
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 oversee the Lower Duwamish Waterway cleanup site, approximately 5 miles of waterway upstream from Harbor Island, for contaminated sediments.
The site, owned by 730 Myrtle LLC, is used for truck parking by Seattle Iron & Metals Corp. Former owners include Tyee Lumber and Manufacturing, Whitehead Co., and Reliable Transfer and Storage Co. Past industrial activities on the site include wood treating and milling and repairing equipment and vehicles.
Hazardous substances released during the past activities to soil and groundwater pose health risks from direct exposure and potential movement into the waterway. Wood preservatives, solvents, and petroleum compounds a are known to be present.
Information about the site’s contamination and cleanup process is available at:
Comments or technical questions may be submitted to Ronald mm, , site manager, 425-649-7185, or Department of Ecology, 3190 160th Ave. S.E., Bellevue WA, 98004-5452.
Stormwater treatment planned
Under a separate water quality permit, Seattle Iron and Metals is preparing to install a treatment system for stormwater that drains off the property. The agreed order requires the company to first study and clean up contamination in places that will be excavated for the treatment system.
Such a partial cleanup conducted before the final cleanup is called an interim action, and is subject to public review and comment prior to Ecology approval. A draft interim action work plan is due from the company this fall.
