Superfund Site Profile
The 90-acre Western Pacific Railroad Co. site is located near Oroville, California. A rail yard operated on site from 1920 until 1982. Railroad activities discharged waste solvents, oils, grease and wastewaters containing heavy metals into an unlined surface impoundment until 1987. A concrete tank containing an unknown, oil-like substance was located on site as well. Following cleanup, EPA took the site off the Superfund program’s National Priorities List (NPL) in 2001.
