Department of Ecology News Release - March 9, 2015
EVERETT – Weyerhaeuser Company’s cleanup of property along the Snohomish River in northern Everett meets state cleanup requirements and the Department of Ecology proposes removing the parcel from its Hazardous Sites List.
Ecology seeks public comment through April 6, 2015, on that proposal and on a five-year site review, required at all cleanup sites that must maintain a special condition.
Comments may be sent to David South, cleanup site manager, Department of Ecology, 3190 160th Ave. S.E., Bellevue WA 98008-5452, or firstname.lastname@example.org.
Weyerhaeuser operated several mills at the 35-acre site from 1914 to 1992, producing pulp, boards and other wood products.
The company cleaned up soil contaminated with polychlorinated biphenyls, chromium, mercury, ethylbenzene, xylenes and petroleum and water contaminated with arsenic and petroleum in various parts of the site. The most-contaminated soil was excavated and hauled to a landfill. Less contaminated soil remains on site. Groundwater was monitored to confirm that natural processes had reduced contamination to levels below the state’s cleanup standard.
Special covenants have been filed with the site’s official property records to protect public safety, health and the environment. These restrictions prohibit using the site’s groundwater for drinking, prohibit disturbance of areas that contain the less-contaminated soils, require reporting of any property transfer to Ecology, among other measures.
Even after removal from Ecology’s hazardous sites list, Ecology will continue to review the site every five years to ensure the effectiveness of the property restrictions.
Copies of the delisting proposal and the most recent five-year review are available at:
An Ecology fact sheet provides background and details about the site’s proposed de-listing and draft review.
