Takes about 19,080 acres of land owned in fee by the Ute Mountain Ute Tribe into federal trust for the Tribe (subject to valid existing rights), makes that land part of the Tribe’s reservation and ineligible for gaming, and requires a boundary survey and related actions within set deadlines. Establishes multiple new public‑land designations across federal lands in Colorado — including Special Management Areas, Wildlife Conservation Areas, Protection Areas, Recreation Management Areas, a Scientific Research and Education Area, and additions to wilderness — and imposes management rules (maps, vehicle/trail limits, grazing and restoration rules, mineral withdrawals, and coordination requirements). The bill also withdraws specified Delta County lands from oil and gas leasing, applies no‑surface‑occupancy restrictions for oil and gas on mapped areas, and preserves limited exceptions (e.g., for capture of mine methane and an existing research laboratory).
