We regulate the air, water, hazardous waste, and composting activities at the Boise White Paper pulp and paper mill in Wallula.

Paper Machine #3 project

The Boise White Paper pulp and paper mill in Wallula submitted applications requesting to modify two pieces of equipment that produce (emit) air pollutants - #3 Paper Machine and #2 M&D Digester. These are called air emission units.

The proposed project will allow the mill to increase production at the paper machine from 800 machine-dried tons of unbleached linerboard each day to 1,400 machine-dried tons (annual average), with a maximum daily production capacity of 1,680 machine-dried tons. It will also increase the pulping capacity of the digester.

Comment period: Aug. 13 - Sept. 14, 2018 
We invite you to comment on the following documents that would allow this project to take place.

Read the public comment notice for information on how to comment.  An open house, followed by a public hearing, will take place on Sept 12. Read the public event listing for more information.

The United States Environmental Protection Agency (EPA) must issue a greenhouse gas PSD permit for this project, and plans to hold a separate comment period. Please visit the EPA's website for more information on the EPA's permit.
