Columbia Gorge Aluminum


The Dept of Ecology (Ecology) approved the final Remedial Investigation (RI) Phase 1 and Phase 2 Workplans.

These describe what needs to be done to investigate contamination on the Site. Read the Public Participation Plan to learn about opportunities to comment and provide input.


Located at 85 John Day Dam road in Goldendale, next to the Columbia River, construction of the former Columbia Gorge Aluminum smelter began in 1969. The smelter operated under various owners until it closed in 2003. Starting in 1980, owners managed hazardous and solid waste at several locations on the site. 

Smelter operations contaminated the soil and groundwater at the site with fluoride, polycyclic aromatic hydrocarbons (PAHs), cyanide, polychlorinated biphenyls (PCBs). The facility was added to the Hazardous Sites list in 1990. 

Agreed Order No. 10483 requires potentially liable persons NSC Smelter, LLC and Lockheed Martin Corp to:

1.  Prepare a RI workplan.
2.  Complete a RI of the Site.
3.  Prepare a RI/Feasibility Study report.
4.  Draft a cleanup action plan.


Under a National Pollutant Discharge Elimination System (NPDES) wastewater permit, the site currently discharges stormwater and a small amount of sanitary wastewater to the Columbia River. Demolition contractors use best management practices to minimize pollutants in the stormwater. Sanitary wastewater is treated using a small actived sludge system prior to combining with stormwater. For more information, read the NPDES permit, fact sheet, and permit modification fact sheet.
