Data Centers and Air Quality

Dell Data Center

Data centers, also called server farms, house the servers that manage email and instant messages, store data, and run computer applications. Grant County has become a popular location for data centers because of its dependable and economical electric supply. The region has a 99.9 percent yearly power reliability rate which is crucial to technology systems management and appealing to data center businesses.

Each data center is equipped with multiple diesel-powered backup generators. Because diesel exhaust is a toxic air pollutant (containing nitrogen dioxide, carbon dioxide, carbon monoxide, organic compounds, and other small particles), Ecology must review air permits before construction. The required air permit is called a Notice of Construction permit. The application must:

  • list all air emissions from the project,
  • identify the applicable federal air regulations,
  • describe their emission control technology,
  • confirm that air emissions will still meet air quality standards.

If emissions exceed air quality standards, a health impact assessment must also be conducted to make sure there is minimal health risk.

A sales tax exemption incentive is available to owners and tenants of eligible data centers (at least 100,000 square feet) in rural counties. A data center must have a building permit to construct, remodel, or expand the center issued between July 1, 2015 and June 30, 2025.

For more tax information, read the Department of Revenue's Tax Incentives Overview fact sheet.
