25 U.S.C. § 321 — Rights-of-way for pipe lines

The Secretary of the Interior is authorized and empowered to grant a right-of-way in the nature of an easement for the construction, operation, and maintenance of pipe lines for the conveyance of oil and gas through any Indian reservation, through any lands held by an Indian tribe or nation in the former Indian Territory, through any lands reserved for an Indian agency or Indian school, or for other purpose in connection with the Indian Service, or through any lands which have been allotted in severalty to any individual Indian under any law or treaty, but which have not been conveyed to the allottee with full power of alienation upon the terms and conditions herein expressed. Before title to rights of way applied for hereunder shall vest, maps of definite location shall be filed with and approved by the Secretary of the Interior: Provided, That before such approval the Secretary of the Interior may, under such rules and regulations as he may prescribe, grant temporary permits revocable in his discretion for the construction of such lines: Provided, That the construction of lateral lines from the main pipe line establishing connection with oil and gas wells on the individual allotments of citizens may be constructed without securing authority from the Secretary of the Interior and without filing maps of definite location, when the consent of the allottee upon whose lands oil or gas wells may be located and of all other allottees through whose lands said lateral pipe lines may pass has been obtained by the pipe-line company: Provided further, That in case it is desired to run a pipe line under the line of any railroad, and satisfactory arrangements cannot be made with the railroad company, then the question shall be referred to the Secretary of the Interior, who shall prescribe the terms and conditions under which the pipe-line company shall be permitted to lay its lines under said railroad. The compensation to be paid the tribes in their tribal capacity and the individual allottees for such right of way through their lands shall be determined in such manner as the Secretary of the Interior may direct, and shall be subject to his final approval. And where such lines are not subject to State or Territorial taxation the company or owner of the line shall pay to the Secretary of the Interior, for the use and benefit of the Indians, such annual tax as he may designate, not exceeding $5 for each ten miles of line so constructed and maintained under such rules and regulations as said Secretary may prescribe. But nothing herein contained shall be so construed as to exempt the owners of such lines from the payment of any tax that may be lawfully assessed against them by either State, Territorial, or municipal authority. And incorporated cities and towns into and through which such pipe lines may be constructed shall have the power to regulate the manner of construction therein, and nothing herein contained shall be so construed as to deny the right of municipal taxation in such towns and cities, and nothing herein shall authorize the use of such right of way except for pipe line, and then only so far as may be necessary for its construction, maintenance, and care: Provided, That the rights herein granted shall not extend beyond a period of twenty years: Provided further, That the Secretary of the Interior, at the expiration of said twenty years, may extend the right to maintain any pipe line constructed under this section for another period not to exceed twenty years from the expiration of the first right, upon such terms and conditions as he may deem proper. The right to alter, amend, or repeal this section is expressly reserved.
