Conditions at Proposal (August 23, 1994): The Reynolds faci lity is a primary ALUMINUM reduction plant where ALUMINA from bau xite is reduced to ALUMINUM. The facility is approximately 1.25 miles north of the City of Troutdale, Oregon. The Columbia River forms its northern border and the Sandy River forms its eastern border. A dike surrounds the plant on the northern and eastern s ides, and protects the plant from floods. Site areas north and e ast of the dike are within the 100-year flood plain. The plant was completed in 1941 for the United States govern ment war-time operations. Reynolds first leased the plant from the government in June 1946, and purchased it in June 1949. Curre ntly, Reynolds owns the 80.25-acre plant area and approximately 5 00 surrounding acres. The ALUMINUM reduction plant has been shut down since November 1991 for economic reasons. Currently, there are approximately 100 workers for maintenance, security, adminis tration, and casting ingots from molten ALUMINUM transported to the plant from the Reynolds reduction plant in Longview, Washingto n. Large quantities of wastes were produced at the Reynolds pla nt during the production of ALUMINUM. Twenty-one separate waste streams were identified by Reynolds in response to an EPA informa tion request letter. Major hazardous substances of concern inclu de polyaromatic HYDROCARBONS (PAHS), ALUMINUM and other metals as sociated with bauxite, CYANIDE, FLUORIDE, and polychlorinated bip henyls (PCBS) from electrical equipment. In May 1993, an EPA contractor collected samples at the Reyn olds site. On-site sampling included surface and subsurface soil , sediment, surface water, ground water and an unknown waste pile . Elevated concentrations of CYANIDE, PAHS, many metals, and flu oride were detected in various sources on site. Elevated levels of CYANIDE and FLUORIDE were detected in several on-site drinking water wells. Significant concentrations of ALUMINUM, BARIUM, ma nganese, CYANIDE, and FLUORIDE were detected in the surface water samples. Concentrations of COPPER and CYANIDE in an on-site dra inage ditch which flows to an on-site lake and then the Columbia River exceeded the freshwater quality criteria promulgated under the Clean Water Act. Elevated concentrations of FLUORIDE, metals , and extremely high concentrations of PAHS were detected in sedi ment samples taken from the ditch and lake. The same contaminant s were also detected in on-site wetlands. The Columbia and Sandy Rivers are used for recreation and fi shing, people reach the rivers through the Reynolds property. An adromous fish are found in both rivers as well as numerous sensit ive environments. The Reynolds Metals Company (RMC) has expressed an interest in investigating and conducting early actions under the EPA Remov al Program. RMC has initiated an integrated assessment under EPA oversight. The scheduled seven week assessment is the first pha se of investigations and is a cooperative effort between RMC and EPA. On-site ground water contamination and newly discovered dum p sites are being characterized and evaluated for expedited respo nse actions. Status (December 1994): RMC completed field work in summer of 1994 which will help determine time-critical actions, non-time -critical actions, and further investigations to be conducted at the site. [The description of the site (release) is based on informati on available at the time the site was scored. The description ma y change as additional information is gathered on the sources and extent of contamination. See 56 FR 5600, February 11, 1991, or subsequent FR notices.]
