Loudoun County board debates air pollution concerns in data center application vote

The Loudoun County Board of Supervisors convened on July 1, 2025, to discuss several pressing issues, primarily focused on the implications of data center developments in the region. The meeting highlighted concerns regarding environmental impacts, power demand, and the future of land use in Loudoun County.

The session began with discussions surrounding a specific rezoning application for a data center. Supervisors raised questions about the potential air pollution generated by data centers, particularly during peak demand periods in hot weather when generators may be activated. Supervisor Armstead expressed deep concern over the environmental implications, emphasizing the community's desire for economic diversification beyond data centers. He stated, "The community has been begging us to curtail this industry and come up with other things to support our economy."

In contrast, Supervisor Kershner defended the air quality in Loudoun County, citing that it is better than 86% of other counties in Virginia and has improved over the past decade. He dismissed pollution concerns as exaggerated and emphasized the economic benefits that data centers bring to the county.

The board also addressed the regulatory framework governing power supply to commercial entities. Supervisor Turner clarified that the board cannot deny applications based on power limitations due to state regulations. He highlighted the existing constraints on the power grid, noting that the main trunk lines in the county are at full capacity, which could lead to future challenges for residents regarding new power lines.

The discussion revealed a divide among supervisors regarding the balance between economic growth through data centers and the potential negative impacts on residents' quality of life. Some supervisors expressed a need for more careful consideration of land use, while others argued for the continued development of data centers as a vital revenue source.

As the meeting progressed, supervisors acknowledged the complexity of the issue, with some expressing uncertainty about their positions. Supervisor Umstot noted the need for further exploration of alternative land uses and the potential for other developments that could benefit the community.

In conclusion, the meeting underscored the ongoing debate in Loudoun County about the future of data centers and their implications for the environment and local residents. The board's discussions highlighted the need for a balanced approach that considers both economic benefits and community concerns as they move forward with land use decisions. Further deliberations and potential follow-up actions are expected as the board continues to navigate these critical issues.
