Senate Bill 127 would regulate the siting and operation of data centers in South Dakota by treating certain impacts from those facilities as a nuisance. The bill defines “data center” broadly to include cloud hosting, colocation, cryptocurrency mining, streaming support, software-as-a-service, and similar digital services. It would prohibit a facility housing a data center from being established within one mile of any residential area, while allowing counties, municipalities, and townships to adopt even stricter siting rules.
The bill also sets an operational standard for noise, barring data centers from exceeding a continuous 45-decibel noise level at the nearest property line of a residential area, measured under federal or local environmental standards. If a data center violates the distance or noise requirements, the bill declares the condition a nuisance and authorizes enforcement actions by a state's attorney or any affected citizen to seek an injunction against the operator and the property owner.
Impact
SB127 would add new nuisance and land-use restrictions to chapter 21-10 of the South Dakota Code, creating statewide minimum setbacks and noise limits for data centers. It would affect developers, operators, landlords, and local governments by limiting where data centers may be located and by exposing noncompliant facilities to nuisance litigation and injunctive relief. The bill also preserves local control by expressly allowing counties, municipalities, and townships to impose more restrictive siting requirements.
Sentiment
The available voting history suggests the bill has received mixed but somewhat cautious support, with a 5-3 vote to defer it to the 41st legislative day. That procedural outcome indicates the proposal was not immediately advanced and likely faced concerns about its scope, timing, or policy effects. No committee transcript is available, so the broader discussion record is limited, but the vote suggests the bill was considered significant enough to remain under review rather than being rejected outright.
Contention
The main points of contention likely involve balancing data center development against nearby residents’ quality of life. Supporters would view the bill as a way to prevent noise and land-use conflicts and to give communities tools to regulate industrial-scale digital facilities. Opponents or skeptics may be concerned that the one-mile setback and 45-decibel limit are too restrictive, could discourage investment, or could be difficult to apply consistently across different local standards. The inclusion of cryptocurrency mining and other broad digital services in the definition of data center may also be a point of debate.
