Air quality notice of construction application – Opportunity to request a public comment period
June 3, 2025, 12 a.m. - June 18, 2025, 11:59 p.m. PT
We propose to approve Viterra’s air quality notice of construction (NOC) application. We will hold a public comment period if one is requested.
Viterra submitted a notice of construction application for their existing oilseed processing facility located at 1875 West First Street in Warden.
Viterra proposes to change their existing conveying and seed cleaning dust collector to remove the air stream from the Hammermill process and route it to a new, separate dust collector.
The proposed changes are:
- Decrease the flow rate of the existing dust collector.
- Add a new dust collector for the Hammermill flow rate.
A dust collector cleans the air by capturing harmful dust and fine particles, helping keep the work environment safe and the air cleaner. Hammer milling is a powerful way to break materials into smaller pieces (comminution) using spinning hammers that hit them at high speed.
Document for review
We determined this proposal satisfies the requirements of Chapter 173-400 WAC. We plan to approve the application. We will hold a public comment period on a draft air permit ("approval order") that includes this change if we receive a written request by June 18, 2025.
To request a public comment period, use one of the ways listed below.
To find out if there are more records for this project, contact our Public Records Office.

Background
A notice of construction permit is required before installing a new source of air pollution or modifying an existing source of air pollution. This permit is sometimes called a "pre-construction permit" because a business must have one before starting construction or operating their business.
A notice of construction air permit limits the amount of air pollutants a business can emit.
