25 CFR § 162.112 - How must records associated with this part be preserved?
(a) Any organization, including tribes and tribal organizations, that have records identified in § 162.111(a) must preserve the records in accordance with approved Departmental records retention procedures under the Federal Records Act, 44 U.S.C. Chapters 29, 31 and 33. These records and related records management practices and safeguards required under the Federal Records Act are subject to inspection by the Secretary and the Archivist of the United States.
(b) A tribe or tribal organization should preserve the records identified in § 162.111(b) for the period of time authorized by the Archivist of the United States for similar Department of the Interior records in accordance with 44 U.S.C. Chapter 33. If a tribe or tribal organization does not preserve records associated with its conduct of business with the Department of the Interior under this part, it may prevent the tribe or tribal organization from being able to adequately document essential transactions or furnish information necessary to protect its legal and financial rights or those of persons directly affected by its activities.
