Second Five-Year Review Report for Taylor Lumber and Treating Superfund Site, Yamhill County, OR. (53 pp, 48.05 MB)


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 McFarland Cascade Holdings (Stella-Jones Corporation) who manufactures treated wood utility poles and railway ties. McFarland Cascade has ongoing obligations related to property use restrictions, and operations and maintenance on the property.
