Alcoa Wenatchee

We regulate the air, water and hazardous waste activities at Alcoa's Wenatchee aluminum smelter in Malaga.

Facility information

This facility is temporarily shut down. When running, it turns alumina ore into aluminum metal. Recycling of aluminum does not take place at this location.

  • At full production, the facility is able to produce about 220,000 tons of aluminum each year.
  • Wastewater is sent to the Columbia River. Though the smelter is currently closed, Alcoa continues to monitor pollutants in their treated sanitary wastewater, non-contact cooling water, and stormwater.
