Draft Data Center General Order Public Comment Period
August 21, 2025, 12 a.m. - September 28, 2025, 11:59 p.m.

This general order is only for data centers located near East Wenatchee, Malaga, or Quincy.


We invite you to comment on the draft data center general order.


The proposed data center general order allows data centers near East Wenatchee, Malaga, and Quincy to install up to 21 diesel emergency generators to provide backup electrical power. Each generator must be not be higher than 4,423 brake horse power (bhp).


Emissions from this project are up to:

  • 0.26 tons per year of ammonia (NH3)
  • 2.04 tons per year of carbon monoxide (CO)
  • 0.17 tons per year diesel engine exhaust particulate (DEEP)
  • 2.39 tons per year of nitrogen dioxide (NO2)
  • 23.85 tons per year of nitrogen oxides (NOx)
  • 1.61 tons per year particulate matter (PM10 and PM2.5)
  • 0.47 tons per year of sulfur dioxide (SO2)
  • 1.44 tons per year volatile organic compounds (VOCs)


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