MEMORANDUM OPINION
BRATTON, District Judge.
This matter came on for evidentiary hearing on the application of the plaintiffs for a preliminary injunction, following which the parties have submitted extensive briefs. The issue for decision in this case is whether the National Environmental Policy Act of 1969 (NEPA), 42 U.S.C.A. § 4321 et seq. (Supp.1971), applies to the Secretary of the Interior when he approves a lease of restricted Indian land under 25 U.S.C.A. § 415 (Supp.1971). The material facts are not in dispute.
On April 17, 1970, a 99 year lease of restricted Indian lands was executed by the Pueblo of Tesuque as lessor and Sangre de Cristo Development Company, Inc., as lessee. The lease provides that Sangre de Cristo, a New Mexico corporation, shall develop the leased premises for residential, recreational and commercial purposes, beginning with a tract consisting of some 1300 acres (Tract I). The lease and accompanying master plan contemplate a small city, and accordingly the lease grants options to Sangre de Cristo on 4,100 acres in addition to Tract I. The residential lots on Tract I vary in size from 1/3 acre to almost one acre, and the tract includes space for a golf course, tennis club, apartment houses and condominiums.
The pueblo is authorized to lease its property by the provisions of 25 U.S.C. A. § 415. This section requires that the Secretary of the Interior approve all leases thereunder and provides a maximum term of 99 years. On May 24, 1970, the lease agreement here involved was approved by the Area Supervisor of the Bureau of Indian Affairs for the New Mexico District, acting on specific authorization of the Secretary of the Interior.
The plaintiffs herein, two individuals who reside near the border of the Tesuque reservation and two non-profit environmental corporations, brought this suit asking that the Secretary's approval of the lease be declared invalid and that further development of the leased premises be enjoined on the grounds that the Secretary did not comply with the provisions of the NEPA. Specifically, the plaintiffs claim that the Secretary violated § 102(C) of the Act (42 U.S.C.A. 4332(C)) because he approved the lease without first obtaining an environmental impact statement as required in that section.[1]
*1260 The defendants, the Secretary of the Interior, the Commissioner of Indian Affairs and the Bureau of Indian Affairs Area Supervisor, do not seriously contest the court's jurisdiction or the standing of the plaintiffs to bring the suit,[2] and they admit that no environmental impact study was ever done on the project contemplated in the lease and that the lease was an action "significantly affecting the quality of the human environment." The sole issue for decision is whether the Secretary's action in approving the lease was "major federal action" as that term is used in § 102(C) of the NEPA.
The lands involved here are owned in fee by the Pueblo of Tesuque, subject to a restraint on alienation without the approval of the Secretary (Pueblo Lands Act, June 7, 1924, 43 Stat. 636). Although the Secretary's approval of the lease herein was required by statute, the United States was not a party to the lease, but rather was acting through the Secretary as a fiduciary or guardian of the interests of the Pueblo in the lease. Thus the only "federal action" occurred not in the lease transaction itself but only in the approval thereof. To call such approval "major federal action" is not warranted in view of the fact that the United States had no interest whatsoever in the lease or in the project of the lessees. The United States did not initiate the lease, participate financially in it, or benefit from it. Its further responsibilities under the lease consist only of subsequent approvals in its role as guardian.
The legislative history of the NEPA is barren of any indication of whether Congress considered the Secretary's approval of Indian leases under 25 U.S.C.A. § 415 to be "major federal action." However, on June 2, 1970 § 415 was amended to provide in part: "Prior to approval of any lease or extension of an existing lease pursuant to this section, the Secretary of the Interior shall first satisfy himself that adequate consideration has been given to * * * the effect on the environment of the uses to which the leased lands will be subject." This amendment effectively requires the Secretary to examine the environmental factors involved in Indian leases and as such serves the same purpose as the NEPA. Congress, therefore, must have considered NEPA inapplicable to Indian leases because otherwise this portion of the amendment to § 415 would have been unnecessary. Such congressional interpretation of its prior Act is not necessarily controlling, but is highly persuasive. The legislative history of the amendment supports this conclusion.
This amendment was made in the Senate Interior and Insular Affairs Committee. *1261 In that Committee's report it was stated with reference to the environmental requirement:
"The concern of the committee stems from the fact that investments made on the basis of such long-term leases may include construction and development without regard to the environmental impact nor appropriate machinery for prevention of pollution.
*   *   *   *   *   *
While it is not the intention of the committee to unduly burden development plans for Indian lands, the committee and the Department of the Interior have an obligation to protect the public interest and safety. The purpose of the committee amendment is to require that the Secretary of the Interior satisfy himself that adequate consideration has been given to the provision of fire and police protection and enforcement of appropriate land use regulations, pollution control and health and safety standards. * * *"
2 U.S.Code Cong. & Admin.News, p. 3243 (1970).
If the NEPA applied to approval of Indian cases under Sec. 415 there would be no reason for such concern or requirement as to the environmental aspects.
Plaintiffs also claim that the Secretary, in approving the Tesuque lease, failed to consider the environmental effect of the proposed project as required by the June 2, 1970, amendment to 25 U.S.C.A. § 415. This claim, however, is without merit since the amendment did not become effective until after the Secretary approved the lease.
The Secretary's approval of the lease in question was not "major federal action" as that term is used in the NEPA and the Secretary was not required to obtain an environmental impact statement thereunder prior to that approval. Accordingly, there appearing no likelihood that the plaintiffs will prevail upon the merits of the action, the motion for a preliminary injunction will be denied.

(ii) any adverse environmental effects which cannot be avoided should the proposal be implemented,
(iii) alternatives to the proposed action,
(iv) the relationship between local short-term uses of man's environment and the maintenance and enhancement of long-term productivity, and
