Point feed project

Comment period: June 13 - July 13, 2018
We invite you to comment on the Intalco aluminum smelter's proposed point feed project Notice of Construction (NOC) air quality order and State Environmental Policy Act (SEPA) Determination of Nonsignificance (DNS).

Intalco produces primary aluminum metal from aluminum ore. It proposes to automate the process used to put the alumina ore into aluminum reduction pots. This project does not allow Intalco to increase production.

Air pollutants expected to decrease due to the project include:

  • Particulate matter (PM10)
  • Total fluoride.
  • Carbon monoxide.
  • Sulfur dioxide.
  • Perfluorocarbon, a greenhouse gas.
Air pollutants expected to increase include:
  • Nitrogen oxide by 38 tons/year.
  • Nitrogen dioxide by 27 tons/year.
The increases will not exceed air quality standards.

Read the comment period notice for information on how to comment.
