Jan. 23, 2020 - Feb. 24, 2020, 5 p.m.

We are accepting comments on the approval order modification for Microsoft MWH in Quincy.

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

Microsoft MWH Data Center (MWH), located at 1515 Port Industrial Parkway in Quincy, currently has an air quality permit, Approval Order 19AQ-E031, to install and operate 117 diesel powered emergency generators, 32 cooling towers, and 136 evaporative coolers. MWH requested a reduction of permitted equipment to 105 engines, 32 cooling towers, and 100 evaporative coolers. MWH also requested to move some of the engines to different locations on site. These modifications were modeled and are included in the Notice of Construction application. All generators will be Tier 2-certified and will be equipped with a catalyzed diesel particulate filter and urea-based selective catalytic reduction to meet emission requirements of U.S. EPA Tier 4 engines. This project will be an overall reduction of emissions from what was previously permitted.
 
Ecology determined this project meets the requirements of Chapters 173-400 and 173-460 WAC, and the public is invited to comment. A public hearing will be held if Ecology determines there is significant public interest.

Background

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.
