S.D. Codified Laws § 10-28-21.5
The railroad shall annually notify the Department of Transportation of completion of any capital project. However, if the cost of the capital project exceeds three hundred thousand dollars, the railroad shall notify the department immediately upon completion. The department may conduct a verification inspection of capital improvement project completion and may audit the capital improvement project according to South Dakota Department of Transportation Audit guidelines and the Federal-Aid Policy Guide 23 CFR Chapter 1, Subchapter B, Part 140, Subpart 1, as amended through January 1, 2014, to determine project value. The department shall report its findings to each county where the railroad has requested a tax credit. Only those capital expenses that have been claimed on the railroad's certification and verified by the department are eligible for a credit pursuant to § 10-28-21.2. Any railroad aggrieved by the decision of the department concerning the eligibility of a claimed capital expenditure for the tax credit authorized by § 10-28-21.2 is entitled to an administrative hearing conducted in accordance with the provisions of chapter 1-26.
