New strict data center rules in Nashville; A report finds where gaps may remain
Nashville has adopted strict data center regulations, including a half-mile buffer from homes and schools, closed-loop cooling requirements, noise monitoring and utility-capacity reviews. A new Metro report says the rules are among the strictest in the country but identifies gaps involving vibration, background noise and wastewater.
Metro Nashville adopted sweeping data center regulations after plans for a facility near the Nashville Zoo prompted community opposition. Councilmember Roland Horton sponsored the rules, which prohibit campus-style facilities and require permitted data centers to use closed-loop cooling, conduct 24-hour noise monitoring, demonstrate adequate utility capacity and remain at least one-half mile from homes, schools and similar locations.
A study requested by the mayor found that Nashville's distance requirements stand out compared with those of other cities, while recommending additional safeguards for vibration, background noise and wastewater. The report also recommends that Metro Nashville Electric Service and the Tennessee Valley Authority create a working group to oversee compliance and determine whether additional resources are needed. The regulations have not yet been applied to a new data center proposal in the area identified in the report.
