EPA Superfund Program: MCCORMICK & BAXTER CREOSOTING CO. (PORTLAND PLANT), PORTLAND, OR

Superfund Site Profile

The McCormick and Baxter Creosoting Co. (Portland Plant) site is a former wood treatment facility located on the Willamette River in Portland, Oregon. The site encompasses about 43 acres on land and 23 acres of river area. Wood treatment operations took place at the site between 1944 and 1991. Wood-treating products used at the site included creosote/diesel oil mixtures, pentachlorophenol (PCP)/diesel oil mixtures, and a variety of water- and ammonia-based solutions containing arsenic, chromium, copper and zinc. Between 1945 and 1969, site operations included the discharge of wastewater and non-contact cooling water directly into the Willamette River. Prior to 1971, boiler water, stormwater and oily wastes were disposed of on the western portion of the site. Wood-treating operations ceased in 1991. Site activities contaminated soil, sediment and groundwater with hazardous chemicals. Following cleanup, operation and maintenance activities and monitoring are ongoing.
