Commissioners approve data center ordinance, lift moratorium

The Troup County Board of Commissioners unanimously approved a new zoning ordinance to regulate data centers in unincorporated Troup County during their regular meeting on Tuesday. Assistant County Manager Jay Anderson provided an overview of the ordinance, which incorporates changes proposed during a previous meeting and public hearing. The new rules require all data centers to obtain a special-use permit and restrict them to industrial zoning, with small data centers (under 5,000 square feet) allowed in light or heavy industrial zones, and larger facilities limited to heavy industrial. Key provisions of the approved ordinance include mandatory closed-loop cooling systems for reduced water usage, connection to public water and sewer systems, and a 1,500-foot setback for all structures and improvements, including parking lots, from sensitive receptors like residences, schools, and hospitals. The maximum allowed height for data centers was reduced from 60 feet to 40 feet, and operational facilities must undergo noise testing for both low and high frequencies. Additionally, backup power generators are now required to be four-tier models to minimize noise and emissions. County Attorney Mark DeGennaro advised the board on the process for future amendments, noting that substantive changes would necessitate returning to the planning board and holding new public hearings. Commission Chairman Patrick Crews acknowledged that the ordinance is a "living document" that will likely be amended multiple times in the future. With the approval of the new ordinance, the county also officially lifted its moratorium on data center development, which was previously set to expire on June 12.
