Alcoa has started demolishing the Intalco smelter west of Ferndale, Washington, marking the end of aluminum production in the Pacific Northwest. The demolition project, approximately 45% complete, follows the smelter's closure in 2020 and the loss of associated jobs.

The Washington state Department of Ecology has published a draft cleanup roadmap and will accept public comments until April 15. Alcoa plans to sell the 1,600-acre site to Calgary-based AltaGas, which is interested in developing a green hydrogen facility, but this plan is currently uncertain due to regulatory issues. The cleanup is expected to address localized soil and potential groundwater contamination.
