SDCL § 31-26-26: Relocation of pipeline--When required.

When any highway along or under which a pipeline approved pursuant to § 31-26-25 has been constructed is changed, removal or relocation of the pipeline is not necessary if the owner or beneficiary of the pipeline and the board of county commissioners agree in writing that removal or relocation is not necessary. However, removal or relocation of a livestock pipeline is required if the board determines it is necessary to improve the highway or otherwise remove the pipeline for any county purpose.
