Microsoft Columbia Data Center, Quincy

Air quality notice of construction application

Dec. 30, 2024, 12 a.m. - Feb. 4, 2025, 11:59 p.m. PT

We propose to approve Microsoft Columbia Data Center’s air quality notice of construction (NOC) application.

Microsoft Corporation – Columbia Data Center requested to update their existing air permit:

  • Match current operations related to yearly load averages
  • Run more generators in bypass mode — 5 generators instead of 2, but for a shorter amount of time

Short-term increases of emissions and modeling of emissions from nonroad engines were evaluated. There were no increases of annual emissions from this change.

Microsoft Columbia Data Center is located at 501 Port Industrial Parkway, in Quincy.

Documents for review

We determined this proposal satisfies the requirements of Chapter 173-400 WAC. We plan to approve the application.

Tentative public hearing

(if requested by January 16, 2025, 11:59 p.m.)
Thursday, January 30, 2025, 6 p.m. online

We will hold a public hearing online if there is significant public interest. If we do not receive significant written requests for a public hearing by January 16, 2025, then the online public hearing will be cancelled.

Background

Data centers, sometimes called server farms, house the servers that manage email, store data, and run computer applications. If you shop on the web or use social media, your information is routed through a data center. Most of the data centers regulated by Ecology are located in Quincy and the Wenatchee area because those areas have dependable, lower cost electricity. Sign up for email updates about data centers.

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.
