Updating Yahoo!’s air permit for a data center in Quincy
Ecology is seeking comments on the changes

SPOKANE – Yahoo! is proposing to expand its operations at their data center in Quincy. In order to expand, their air quality permit needs to be updated to ensure that human health and the environment are protected.

Data centers house servers that store digital data, handle email, manage instant messages and run applications for computers. Yahoo! uses backup generators powered by diesel engines to keep servers functioning in case of power outages.

The Washington Department of Ecology is seeking comments on the updates to Yahoo!’s original permit that was issued in 2011. With the updated permit they can operate an additional 25 backup diesel generators.

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

The permit includes conditions to protect the public from air pollution including fuel limits and specified hours of operation for generators.

Public hearing

Ecology is hosting a public hearing on the air quality permit that begins at 5 p.m. on March 31 at the Quincy Community Center, 115 F St. S.W., Quincy, Wash. Formal testimony starts at 6:30 p.m.

Submit comments

Comments and questions on the draft permit should be addressed to Kari Johnson, Department of Ecology, Air Quality Program, 4601 N. Monroe, Spokane, Wash. 99205.

Comments will be accepted from February 25 through April 4.

Review the revised permit
