S.D. Codified Laws § 49-16A-100.5
Unless otherwise agreed by the parties, a utility that crosses a railroad right-of-way, other than a crossing within the public right-of-way, shall pay the railroad a one-time standard crossing fee of seven hundred fifty dollars for each crossing. The standard crossing fee is in lieu of any license, permit, application, processing fee, or any other fees or charges to reimburse the railroad for the direct expenses incurred by the railroad as a result of the crossing. No other fee may be assessed by the railroad or by any railroad agent, contractor, or assignee to the utility or to any agent or contractor of the utility. The utility shall also reimburse the railroad for any reasonable and necessary flagging expense associated with a crossing, based on the railroad traffic at the crossing, in addition to the standard crossing fee. No crossing fee is required if the crossing is located within a public right-of-way.
