The Virginia Department of Environmental Quality (DEQ) issued a fine of nearly $2.5 million to a Microsoft data center for exceeding allowable air emissions limitsthe largest civil penalty against a data center in Virginia’s history.
Key details from the reporting:
The Incident: In June 2025, an electrical substation failed at Microsoft’s data center facility in Leesburg, Virginia (located in Loudoun County). To keep operations running, the facility ran 62 emergency backup generators continuously over a seven-day period.
The Violations: Running the emergency generators for that duration caused the facility to breach its permitted fuel emissions thresholds for several air pollutants, including carbon monoxide (CO), volatile organic compounds (VOC), and fine particulate matter (PM10 and PM2.5).
The Settlement: As part of the resolution, Microsoft agreed to invest $2.4 million into a local environmental initiative. The Virginia DEQ plans to use these funds to deploy dozens of air-quality monitoring sensors across Loudoun County, specifically targeting areas with high data center density.
Microsoft’s Response: The company stated it is supporting the DEQ’s expansion of regional air monitoring to provide community insight into local air quality.
Broader Impact: Loudoun Countyknown as “Data Center Alley” with more than 250 operational facilitieshas faced rising local pushback over pollution, noise, and power grid strain. Following mounting community concerns, the Loudoun County Board of Supervisors voted 7–1 to enact a one-year pause on approving new data center applications while considering more stringent environmental and zoning standards.
