Sabey Data Center, East Wenatche

Air Quality Notice of Construction application

April 16, 2019 - May 16, 2019

Sabey Data Center Properties is an existing source of air emissions located at 4405 Grant Road, East Wenatchee, WA 98802 in Douglas County. The proposed action is the installation of a new data center campus, Intergate Columbia II, next to and directly west of the existing Intergate Columbia I campus. Ccombustion of ultra-low-sulfur diesel (No. 2 fuel oil) in up to 22 emergency generators for the production of electricity will be new sources of pollution. Up to twenty 2,750 kW diesel-fired generator sets, and two 300 kW diesel-fired generator sets, are proposed. Air contaminant emissions will include criteria air pollutants and toxic air pollutants.

The Notice of Construction (NOC) Approval Order specifies the facility’s air quality regulatory requirements as conditions, emission limits, and work practices. Ecology expects to approve the application and invites the public to comment. The public may request a public hearing. The request must include a reason for the request and why a public hearing is needed. A public hearing will be held if Ecology determines there is significant public interest.

Written comments on the proposed action will be accepted through May 16, 2019

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.
