Location & History
Columbia Gorge Aluminum LLC operates a primary aluminum smelter on a portion of 7000
acres along the Columbia River beside the John Day Dam.
Harvey Aluminum began aluminum smelting operations in 1970. Martin Marietta purchased the
facility in 1971 and operated it until 1985. It was then purchased by Commonwealth Aluminum
which operated the smelter until 1987. After one-half year of inactivity, Columbia Aluminum
purchased and restarted the plant. The plant was later sold to a private party operating
the facility as Goldendale Aluminum Company. The company is now operated under the name Columbia
Gorge Aluminum LLC. The present facility consists of: carbon paste
plant, four reduction cell lines, a casthouse, a laboratory, administrative offices, and a
sewage treatment plant. Goldendale has one wastewater discharge outfall that empties, after
treatment, directly into the Columbia River.
Capacities:
The company can produce approximately 178,000 tons of aluminum and aluminum alloys per year.
