Scope
South Dakota Senate Bill 127 (2026), as introduced, would have barred establishing a facility housing a data center within one mile of any residential area from 1 July 2026, while letting counties, municipalities and townships adopt stricter siting rules, capped continuous data center noise at forty-five decibels at the nearest residential property line, and declared violations a nuisance. It was amended in committee and deferred to the 41st legislative day on 18 February 2026.

About this date
This record was last checked before the tracker date, 30 October 2026. An earlier check date does not by itself mean the record's status has changed.
Summary
South Dakota Senate Bill 127 of 2026 proposed a one-mile residential setback and a 45-decibel noise limit for data centers, with violations treated as nuisances. The Senate State Affairs Committee adopted an amendment and then deferred the bill to the 41st legislative day on 18 February 2026, 5 to 3.
What this does not establish
- The record describes the bill as introduced; the index shows no later version was enacted.
- A committee amendment was adopted before the bill ended; the amended text was not opened.
- Deferral to the 41st legislative day, a day the session does not reach, is how South Dakota committees end a bill; the end date recorded here is that day.
Unresolved questions
None recorded.
Relationships
Supersession means a later instrument replaces the earlier legal effect. Repeal links identify the repeal instrument and the measure it ends. A later implementation or related letter is not treated as a replacement unless the record says so.
- No related action is recorded.
