    Stage of Clean-up: Construction Underway

    Conditions at proposal (October 26, 1989): The Union Pacific Railroad Co. Tie-Treating Plant covers 83 acres in a mixed commercial and residential area just south of the Columbia River in the City of The Dalles, Wasco County, Oregon. Union Pacific owned the wood treatment facility from 1926 to late 1987, when equipment and structures were purchased by Kerr-McGee Chemical Corp.; however, Union Pacific retained ownership of the land and responsibility for all pre-1987 contamination of facility soil and ground water. The plant primarily treated railroad ties for Union Pacific, but also treated wood for other commercial users across the United States. From 1959 to November 1987, J. H. Baxter Co. operated the plant for Union Pacific. The facility treated wood with ammoniacal COPPER arsenate, CREOSOTE, a creosote/fuel OIL mixture, and PENTACHLOROPHENOL. Spills of treatment solutions on-site and waste water ponds no longer in use are thought to be the main source of contamination of soil and ground water. Improvements in the waste water treatment system allow the site to operate as a zero discharge facility. In 1984, Union Pacific began a comprehensive investigation of soil and ground water at the site.  More...
