The Three Affiliated Tribes (TAT) representing the Mandan, Hidatsa, and Arikara Nation (MHA Nation) is a sovereign Indian nation with inherent powers of self-government. The MHA Nation has requested that United States Department of the Interior (DOI)-Bureau of Indian Affairs (BIA) accept 468.39 acres of land into trust status for the Tribes. This land is located within the Fort Berthold Indian Reservation boundaries. The land proposed to be taken into trust is located in the northeast corner of the Fort Berthold Indian Reservation along the south side of North Dakota Highway 23, about 2 miles west of the turnoff to Makoti, North Dakota in Sections 19 and 20 of Township 152 North, Range 87 West. The MHA Nation proposes to construct and operate a new 13,000 barrel (bbl) of production per day clean fuels refinery and grow hay for buffalo on the Fort Berthold Indian Reservation located near Makoti, North Dakota. The MHA Nation would own the refinery. The proposed facility would refine synthetic crude oil from Canada into gasoline and diesel fuels. The MHA Nation has also applied to the U. S. Environmental Protection Agency (EPA) for a Clean Water Act (CWA), National Pollutant Discharge Elimination System (NPDES) wastewater discharge permit for the refinery. The refinery would be considered a "new source" under the NPDES permit regulations.
