TIE PLANT RD-IN CITY LIMITS
The Union Pacific Railroad Co. Tie Treating Plant site covers 83 acres in a mixed commercial and residential area approximately 500 feet south of the Columbia River in Wasco County, The Dalles, Oregon. Union Pacific owned the wood treatment facility from 1926 until late 1987, when equipment and structures were purchased by Kerr-McGee Chemical Corporation. However, Union Pacific retained ownership of the land and responsibility for all pre-1987 contamination of soil and groundwater. The plant primarily treated railroad ties for Union Pacific, but also treated wood for other commercial users across the United States. From 1959 to 1987, J. H. Baxter Co. operated the plant for Union Pacific. The facility treated wood with copper arsenate, creosote, a creosote/fuel mixture, and pentachlorophenol. Spills of treatment solutions and wastewater ponds in use were the main sources of contamination. Groundwater is used by over 11,000 people located within 3 miles of the site. Site Responsibility: This site is being addressed through state actions and potentially responsible parties' actions.
