Planning commission adds utility, noise and decommissioning provisions to proposed data‑center rules
Summary
Commissioners voted unanimously to add requirements for utility‑capacity letters, an acoustic study and decommissioning bonds to the county’s draft data‑center standards; staff will forward revised language to the Board of Commissioners for first reading.
The Spalding County Planning Commission voted to expand draft data‑center standards to require utility capacity letters for electricity, water, sewer and natural gas; an acoustic (noise) study prepared by an acoustic engineer; and explicit decommissioning and bonding requirements. The commission adopted the additions unanimously and asked staff to incorporate the language for the Board of Commissioners’ first reading.
Resident Dina Ray, who said she lives on Parham Road, urged the commission to require both noise studies and utility capacity documentation. "We are asking you to have the developer provide an acoustic engineer that will provide sound studies...and provide utility capacity letters for water, sewer, and electricity infrastructure," Ray said, adding that she recommended closed‑loop cooling to limit water demand for very large facilities.
David (county planning staff) told the commission staff had adapted decommissioning language from another jurisdiction to address the lifecycle of data centers, including procedures for site remediation if a facility is abandoned. Commissioners pressed staff to clarify timing and financial assurance. The ordinance as drafted requires an applicant to provide an estimate of decommissioning costs (removal of equipment, hazardous‑material disposal, remediation and site restoration); the applicant must post a bond sized to that estimate. "The bond’s established based off" the developer’s provided estimate, staff said.
Commission discussion emphasized three priorities: (1) confirm utility availability before a permit is issued by requiring capacity letters from providers; (2) require an acoustic study and mitigation plan to address generator and cooling noise; and (3) include decommissioning financial assurance so the county is not left with an environmental or visual cleanup burden if a facility goes defunct. One commissioner asked staff to include natural gas in the utility letters in addition to power, water and sewer; the motion adopted that change.
Commissioners asked staff to add the agreed language and forward the revised ordinance to the Board of Commissioners for a first reading (staff identified April 24 as the intended BOC meeting). The commission also noted the decommissioning bond amount will vary by project and should be calculated from the applicant’s submitted cost estimate rather than a fixed sum.
Why it matters: hyperscale and large data‑center proposals can have high power and water demands, on‑site generators that generate noise and long term site impacts if a facility is abandoned. The additions the commission approved are intended to ensure utilities can serve projects and that the county has both technical studies and financial assurance to manage noise and end‑of‑life impacts.
Implementation and next steps: staff will revise the draft ordinance to incorporate the utility‑capacity letter requirement, acoustic study language and decommissioning/bond provisions and present the revised text to the Board of Commissioners for first reading.
