Site Characteristics

General Site Description: The site is located at 5100 NE Sundial Road, Troutdale. The site is bounded to the north by the Columbia River, to the east by the Sandy River and is 1.5 miles east of the City of Portland Columbia South Shore Well Field.
Site History: The United States government built the primary aluminum reduction plant, where alumina from bauxite ore was converted to aluminum, in 1941 to support wartime operations. Reynolds Metals Company leased the plant in June 1946, and purchased it in June 1949. Reynolds used the plant to cast ingots from molten aluminum imported from another plant from 1992 to 1998. Aluminum production resumed from 1998 to 2000. Reynolds operated the plant until summer 2000, when it was temporarily shut down. Alcoa purchased Reynolds in 1998, and announced in February 2002, that the plant would be closed and demolished and the property sold.
Contamination Information: (4/15/2003 MDK/SRS) During the production process, molten aluminum would be handled in large, carbon-lined pots. Trace amounts of other metals such as copper, chromium, and beryllium were sometimes added to make aluminum alloys. Spent carbon potliners containing cyanides were disposed of on-site until 1975. DEQ visited the site in 1981 and collected three on-site well samples. Two groundwater samples contained cyanide (up to 4 ppb). Aluminum production at the site halted in November 1991. In April 1992, free mercury was found in the storage/scrap yard in the SE corner of the site, probably from old arc rectifiers. 600 tons of contaminated soil was removed from this area. EPA collected samples at the site in May 1993. Cyanides were detected in some of the wells; two wells contained arsenic. Groundwater samples also contained barium, magnesium, and fluorides. Soil and sediments from most sample locations, including Company Lake and the wetlands north of the dike, contained significant levels of many metals, PAHs, and fluorides. DEQ's Site Response program began investigating the site in November 1993. EPA listed the site on the National Priorities List (NPL) in December 1994, and took the lead in investigating and cleaning up the site.
Manner and Time of Release: Past practices. Most releases probably occurred from 1946 to 1975.
Hazardous Substances/Waste Types: Aluminum potlining wastes, cyanide, PCBs, heavy metals, PAHs, and fluorides.
Pathways: There is potential for groundwater and soil contamination with PCBs and capacitor oils, because over 100 large PCB capacitors may have been buried sometime between the mid-1960s and the 1980s in the vicinity of Company Lake.
Environmental/Health Threats: Heavy metals, PAHs, and fluoride in soil and sediment samples near and in Company Lake and adjacent wetlands. Flouride also in groundwater.
Status of Investigative or Remedial Action: (4/15/2003 MDK/SRS) Six removal actions were taken at the site in 1995 and 1996. About 13,900 tons of cryolite, 11,000 tons of spent potliner waste, 2,600 tons of diesel-contaminated soil, and 580 tons of PCB-contaminated dust, soil, and debris were separately excavated and disposed of off-site. In addition, seven on-site production wells were abandoned, and 21 dewatering sumps contaminated with fluoride, cyanide, and PAHs were cleaned out. Reynolds began work on the RI/FS in 1996. The RI/FS identified several additional sources of contamination, including two old landfills (North Landfill and South Landfill), a former scrap yard, and a surface water impoundment (Company Lake). Additional removals were conducted between 1997 and 1999, including the removal of PCB-contaminated soil from the South Wetlands and removal of soil and sediments from South Ditch. A partial removal of 3,300 cubic yards of Company Lake sediments occurred in October 2001 to test dewatering as an alternate technology to dredging. EPA issued an interim ROD in September 2002. The chosen remedy includes excavating South Landfill; excavating the eastern portion of North Landfill and capping the rest; and excavating the remainder of Company Lake. Excavated materials would be disposed of off-site. Contaminated groundwater would be extracted, deep plumes contained using production wells, and the combined flow (est. 1,240 gallons per minute) would be discharged to the Columbia River. (6/20/05 MDK/CU&ER) Remediation at the company lake, north landfill, scrap yard, and south landfill was completed during the 2003 and 2004 construction season with contaminated soil and sediment disposed off-site. The focused extraction system was installed in late 2004. The groundwater monitoring network was revised and completed during late 2004 and early 2005. Plant demolition, with additional site characterization, has been on-going since late 2003. A residual risk assessment will be conducted in mid 2005. The Port of Portland is negotiating a Prospective Purchaser Agreement (PPA) with DEQ anticipating sale of the property at the end of 2005.

(12/28/06 MDK/CU&ER) Post-Demolition Remedial Investigation and Post-Demolition Residual Risk Assessments reports submitted in June 2006. Final site ROD issued by EPA on September 29, 2006. All soil and debris cleanup completed and focused groundwater extraction and optimized pumping system is operating. Reynolds/Alcoa will begin negotiations for consent decree with EPA and DEQ in January 2007. NRD mitigation work completed and will be incorporated into consent decree. Port of Portland in process of negotiating prospective purchaser agreement with DEQ for purchase of the Reynolds property.
(1/28/10 MDK/CU&ER) Operation of pump & treat final remedy ongoing with monitoring and maintenance performed by Port of Portland. FedEx redeveloping a portion of the property by construction of new parcel distribution center to open in 2010. Port constructed Swigert Way and utlities installation. DEQ negotiating Consent Judgment prospective purchaser agreement with City of Troutdale for acquisition of Swigert Way. During Swigert Way construction, the Port encountered unexpected contamination identified as likley from the Reynolds site adjacent to and extending beneath Sundial Road at southwest property margin and submitted a report with sampling results to DEQ. EPA, DEQ, Reynolds, Port and City of Troutdale currently evaluating appropriate action and party to address this discovered area of contamination.

(04.23.14) Ongoing remedial action consists of pump & treat of groundwater in the former scrap yard area. The EPA, the lead agency for the site, conducts five year reviews. The most recent Five-Year Report Report for Reynolds Metals Superfund Site issued in October 2013.
