A legal agreement with the Port of Ridgefield will lead to more cleanup work near the former Pacific Wood Treating site in Clark County.
From 1996 to 2013, the port (the current site owner) removed 24,800 gallons of liquid contamination, 1.5 million pounds of contaminated sludge, and contamination from more than 144 million gallons of groundwater. The port also covered the property using two or more feet of clean soil.
The Washington Department of Ecology is seeking comments until Jan. 8, 2015, on an agreed order. That’s a legal agreement between Ecology and the port, which requires the port to test soil for dioxin contamination and to study cleanup options.
This summer, the port began cleaning up off-property areas, including a railroad overpass area, Carty Lake and Lake River. In Carty Lake and Lake River, the port has been removing sediments that were polluted with wood treating chemicals.
The port will provide its proposed sampling plan to Ecology in January 2015.
