CyrusOne Data Center 30-day Public Comment Period June 17 through July 25, 2024

This is a 30-day public comment period for the review of CyrusOne Data Center's draft permit, technical support document, and notice of construction application with associated documents.

CyrusOne Data Center is requesting to replace two previously-permitted (but not bought or installed) 750kW emergency generators for the administrative building. These two emergency generators were not bought because of facility construction delays. When the building was ready for the emergency generators, the specific approved model was no longer available.

CyrusOne is requesting to update their air permit (“approval order”) with two newer emergency generator models of the same, manufacturer, size and output, while maintaining their permit limits and conditions.

The emissions are not the same between the previously-permitted 750kW emergency generators and the newer ones. In some areas, emissions are slightly higher and in other areas, emissions are slightly lower. Overall, emission change is small.

We determined this proposal satisfies the requirements of Chapter 173-400 WAC. The public is invited to comment.

Tentative public hearing

Date/Time: Tuesday, July 16, 2024, 6 p.m. online (webinar)

An online public hearing will be held if we determine there is significant public interest. If not significant written requests for an online public hearing are received by Monday, July 8, 2024, then the online public hearing will be cancelled.

Comment period ends Thursday, July 25, 2024.
