OB-3 Resource Management, Warden
Air quality notice of construction application – Opportunity to request a public comment period
March 17, 2025, 12 a.m. - April 1, 2025, 11:59 p.m. PT
We propose to approve OB-3 Resource Management’s air quality notice of construction (NOC) application. We will hold a public comment period if one is requested.
OB-3 Resource Management submitted a notice of construction application for their wastewater treatment facility located at 1201 Basin Street, in Warden. OB-3 plans to change their gas purification process from an iron sponge to a granular ferric hydroxide process.
- Iron sponge process is used for low levels of hydrogen sulfide (H2S).
- Granular ferric hydroxide process removes hydrogen sulfide more efficiently.
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 April 1, 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.
