We are accepting comments on the expansion of H5 Data Center in Quincy.

Para asistencia en español: preguntas@ecy.wa.gov.

H5 Data Center submitted an air quality Notice of Construction application to expand their existing data center. The data center is located at 1711 "M" Street NE in Quincy. H5 Data Center has 6 emergency generators and 4 cooling towers.

The proposed expansion will add:

  • 12 new emergency generators
  • 8 cooling towers

We determined this proposal satisfies the requirements of Chapters 173-400 and 173-460 WAC.

An online public hearing will be held if Ecology determines there is significant public interest. Submit a written request for an online public hearing by Nov. 19, 2021.

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 Washington's data centers are located in Quincy because the area has dependable, lower cost electricity.

Diesel engine exhaust contains fine particles that can cause health problems for people who are exposed frequently and at high enough levels.
