Alcoa Intalco

We regulate the air, water, hazardous waste, and cleanup activities at the Alcoa Intalco Aluminum Corporation facility in Ferndale.

Air quality permit violation

On Jan. 30, 2019, we issued a $27,500 penalty (pdf) to the Intalco aluminum smelter in Ferndale for air quality violations.

What happened?

In 2016, Intalco made changes in its operations to prepare for a planned shutdown. That shutdown was canceled, but the operational changes and loss of trained staff led to issues at the smelter.

This caused a number of violations of the facility’s air quality permit — exceeding the fluoride limit 10 times and particulate limit once — between January 2017 and April 2018. 

On August 1, 2018, we issued Notices of Violation 15749 (pdf) and 15812 (pdf).
