This bill significantly enhances the ability of Indian tribes to manage and develop their trust or restricted lands by streamlining processes for leases and rights-of-way, fostering greater tribal self-determination and economic growth. It amends the Act of August 9, 1955, commonly known as the Long-Term Leasing Act, and the Act of February 5, 1948, which governs rights-of-way across Indian land. The legislation modifies the Long-Term Leasing Act by expanding the definition of "Indian tribe" for leasing purposes and removing federal term limits for leases on trust or restricted lands. This change grants tribes greater flexibility in negotiating lease durations, allowing for agreements that better suit their long-term economic and development goals. A key provision allows Indian tribes to grant rights-of-way over their Tribal land for any purpose without requiring direct approval from the Secretary of the Interior. This is contingent upon the tribe operating under a Tribal regulation that has been approved by the Secretary, which must include an environmental review process with public comment opportunities. When the Secretary reviews and approves these tribal regulations, the decision is explicitly exempt from the requirements of the National Environmental Policy Act (NEPA) , the National Historic Preservation Act, and the Endangered Species Act (ESA) , thereby accelerating the approval timeline. While the United States is not liable for losses from tribally granted rights-of-way, the Secretary retains the authority to enforce or cancel such rights-of-way to fulfill trust responsibilities. The bill also establishes a process for interested parties to petition the Secretary to review tribal compliance with their approved regulations, with potential remedies including the Secretary reassuming approval authority after a hearing and opportunity to cure.
