Nashville's Data Center Rules Are Strong But Have Gaps, Mayor's Report Warns
A mayor-ordered assessment found that Nashville’s new data center regulations provide a strong foundation but leave unanswered questions about vibration, cooling-system wastewater and enforcement capacity. The Metro Council rules restrict facility locations and size, while a temporary moratorium on new data center activity remains in effect through December.
Mayor Freddie O’Connell commissioned an assessment of Nashville’s data center regulations after Metro Council adopted restrictions in July. The rules prohibit hyperscale campuses in Davidson County, limit larger facilities to heavy-industrial areas, impose noise and renewable-energy requirements, and require smaller proposals to receive a special exemption and public hearing. A temporary moratorium on new data center permits followed the ordinance and is expected to remain in place through December 1 or the end of December, according to differing local reports.
The assessment identified persistent equipment vibration, wastewater from cooling systems and Metro’s ability to enforce the rules as areas requiring further study. It recommended examining the cumulative effects of multiple facilities and creating a working group of Metro departments and utilities. Council member Jacob Kupin said the city must continue reassessing its approach, while Drew Small of No New Data Centers called for stronger oversight and independent monitoring after helping organize opposition to a proposed facility near the Nashville Zoo.
