US SB3383

Expands the Long-Term Leasing Act to allow all federally recognized Indian tribes to lease trust or restricted lands without term limits, removing the previous 25-year and 99-year lease duration caps

Authorizes Indian tribes to grant rights-of-way across their tribal lands for any purpose without requiring Secretary of the Interior approval, provided the tribe has an approved tribal regulation in place

Requires tribes seeking independent right-of-way authority to submit tribal regulations to the Secretary of the Interior for approval within 180 days, including environmental review processes that identify significant impacts and allow public comment

Exempts the Secretary of the Interior from NEPA, the National Historic Preservation Act, and the Endangered Species Act when approving tribal regulations under this legislation

Preserves tribal sovereign immunity and jurisdiction over land subject to rights-of-way, shields the United States from liability for losses from tribally-granted rights-of-way, and allows the Secretary to enforce or cancel rights-of-way to fulfill federal trust obligations
