Microsoft MWH Data Center, Quincy

Air Quality Notice of Construction Application

June 8, 2022 - July 8, 2022, 11:59 p.m.

Ecology proposes to approve Microsoft MWH's air quality notice of construction (NOC) application.

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

Microsoft Corporation’s MWH Data Center is requesting to amend their current Approval Order 20AQ-E005 to add renewable diesel fuel as a fuel option for its emergency engines. MWH Data Center is located at 1515 Port Industrial Parkway in Quincy. The facility was previously only permitted to use diesel fuel equivalent to on-road specification No. 2 distillate fuel oil (containing less than 15 parts per million sulfur) for its emergency engines. Renewable diesel fuel containing less than 15 parts per million sulfur can be used to fuel the data center’s emergency engines with comparable or lower emissions than that of the same engine model running on No. 2 diesel fuel. There are no anticipated emission increases from this proposal

We determined this proposal satisfies the requirements of Chapter 173-400 WAC and Chapter 173-460 WAC. We will hold an online public meeting if 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.
