Comment Period

CyrusOne Data Center, Quincy

Draft Air Quality Permit - Public Comment Period

May 9, 2019 - June 17, 2019

CyrusOne is a colocation data center, meaning that CyrusOne owns data centers in which other companies lease space for servers and other computing hardware. Their corporate address is 1649 West Frankford Road, Carrollton, Texas, 75007. CyrusOne proposes to construct and operate a new data center complex in Quincy, Wash. The proposed complex will be located in Grant County at 1025 NW D Street in Quincy.

To ensure uninterrupted electrical power supply, CyrusOne proposes to use:
  • Forty 2.25-megawatt diesel powered emergency generators to provide backup power to server buildings.
  • Two 750-kilowatt diesel powered emergency generators to provide backup power for the administrative and support functions of the data center complex.
Although the proposed engines will only operate over a limited time (up to 38 hours per year per engine) two toxic air pollutants -  diesel engine exhaust particulate matter and nitrogen dioxide - may be emitted at rates that exceed screening thresholds. As a result, CyrusOne submitted a health impact assessment describing the increased health risks from their potential emissions. 

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

Join us for a public meeting and hearing:
June 13, 2019 at 5:30 p.m.
Quincy Community Center
101 F St. SW, Quincy, WA, 98848

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.
