The Koppers (Oroville Plant) site is a 200-acre operating wood treating plant in Butte County, California, just south of Oroville. Although there is a history of wood treating operations at the site, wood treating operations were greatly expanded in 1955 when Koppers Company, Inc. became the owner and operator. Chemical preservatives including pentachlophenol (PCP), creosote, and chlorinated copper arsenate solution have been used in the wood treating processes. Wastewater discharge and other site activities have resulted in contamination of unlined ponds, soil, and debris. Pursuant to a State order, Koppers conducted cleanup activities from 1973-74, including ground water pumping and discharge to spray fields and offsite disposal of contaminated debris, and process changes, including construction of a wastewater treatment plant. In 1986 Koppers provided an alternate water supply for domestic uses to affected residents. The selected remedial action for this site includes a soil component and a ground water component.
