|Five Year Review|
On May 15, 2012, we completed the first required Five-Year Review of the cleanup. We evaluated the site cleanup to make sure that the cleanup is working properly and continues to protect human health and the environment.
In 2008, we completed the final cleanup of this site: excavated contaminated soils from five acres of the site; cleaned and restored adjacent roadside ditches and ditches flowing to the South Yamhill River; replaced an existing asphalt cap in the wood-treating area with a new low permeability asphalt cap; disposed stockpiled soil storage cells off-site; and upgraded the storm water conveyance systems. In 2009-2010, we completed long-term operation and maintenance plan and a groundwater monitoring plan. In 2011 we implemented institutional controls to restrict groundwater use and non-industrial land use at the site and began annual groundwater monitoring and sampling. The Oregon Department of Environmental Quality is now overseeing the long-term groundwater monitoring and sampling at this site.
Taylor Lumber and Treating operated a wood-treating plant at 22125 SW Rock Creek Road in Sheridan, Oregon. For over thirty years, toxic and cancer-causing chemicals, such as creosote and pentachlorophenol (PCP), were used to preserve wood. Many wood-treating chemical spills contaminated soil and groundwater at the site. The property is now owned and operated by Pacific Wood Preserving of Oregon who began wood-treating operations in June 2002.
