S. 2088 would direct the Department of the Interior (DOI) to place approximately 40 acres of land owned by the Oglala Sioux and Cheyenne River Sioux Tribes in restricted fee status. The two tribes would retain ownership of the land, and the land could not be transferred without the consent of the Congress and the tribes. S. 2088 would limit the use of the land to a memorial and sacred site and prohibit commercial development and gaming activity as outlined in a covenant signed in October 2022. The bill also would require DOI to make any necessary corrections to the survey and legal description of the land. Using information from the department, CBO estimates that the administrative costs to implement S. 2088 would not be significant.
