WHAT'S HAPPENING NOW
Columbia River sediment cleanup
Cleanup Action Plan and Consent Decree
Agreed Order 8940 required Millennium and Northwest Alloys (a subsidiary of Alcoa) to remove sediments contaminated with polycyclic aromatic hydrocarbons (PAHs) from a small area of the Columbia River next to the former Reynolds Metals aluminum smelter in Longview.
Work on this project took place during the Nov - Dec 2016 "fish window," a time when fish are least likely to be impacted. Sediment removed was sent to the Wasco County landfill in Oregon for disposal. Clean, sandy backfill replaced what was removed.
Millennium is working on the final report. For more information, read the:
We're currently working to finalize the Cleanup Action Plan and Consent Decree for the cleanup of contamination from former aluminum smelting operations at this site. The comment period on this action ended March 18, 2016.

Remedial Investigation/Feasibility Study (RI/FS)
The 2015 RI/FS is a support document to the CAP and CD. It identifies contamination at the site from past aluminum smelting activities, and options for cleanup of the contamination.
These documents are also available at the Longview Public Library. If you'd like a DVD copy of these files, contact Angie Fritz at email@example.com or (360) 407-7393.
A thorough investigation and cleanup of this site is a high priority for Ecology. Property owner Northwest Alloys, Inc. (NWA, a subsidiary of Alcoa, Inc.) and Millennium Bulk Terminals, Longview are legally responsible for the cleanup, including paying for and performing the work.
Please read the Public Participation Plan for more information about opportunities for public review and comment on the cleanup activities at this site.

Portions of the site were contaminated by the former aluminum smelter operations:
- Soils show elevated levels of fluoride and polycyclic aromatic hydrocarbons (PAHs) and total petroleum hydrocarbons (TPHs)
- Groundwater contains fluoride and PAHs
