SDCL § 10-47B-180: Interstate fuel user required to keep operational records.

Any person holding an interstate fuel user license issued by this state shall make and keep for the current calendar year plus the three prior calendar years, the operational records as may be reasonably required by the secretary. If in the normal conduct of business, the required records are maintained and kept at any office located outside of South Dakota, compliance with this section can be accomplished if the records are made available for audit purposes at a location within the State of South Dakota. If required operational records are not made available at a location within this state, the licensee is liable to this state for reimbursement of actual per diem travel expenses incurred in conducting the audit at the out-of-state site. Per diem expense reimbursement shall be assessed based on the prevailing out-of-state travel expense rates for the State of South Dakota.
