WestRock, Tacoma

We regulate the air, water, and hazardous waste activities at the WestRock pulp and paper mill in Tacoma.

Steam limit project cancelled

In 2018, we held a public comment period and events on:

  • Proposed changes to air quality notice of construction order 4153-AQ07.
  • A State Environmental Policy Act Mitigated Determination of Nonsignificance (MDNS).

These related to a request from the WestRock Tacoma pulp and paper mill to increase the use of its natural gas boiler.

On Dec. 9, 2019, WestRock withdrew its application for the project. As a result, the project will not take place. Ecology will not modify the Order and the MDNS associated with the requested modification is withdrawn.

  • With around 400 employees, the mill makes about 1,400 tons of bleached and unbleached packaging-grade paper, linerboard, and unbleached pulp each day.
