As soon as practicable after the effective date of the transfer of jurisdiction under section 460lll–41 of this title, the Secretary shall prepare a land and resource management plan for the Recreation Area in conformity with the National Forest Management Act of 1976 (16 U.S.C. 472a et seq.) and other applicable law.

Until adoption of the land and resource management plan, the Secretary may use, as appropriate, the existing Tennessee Valley Authority Natural Resource Management Plan to provide interim management direction. Use of all or a portion of the management plan by the Secretary shall not be considered to be a major Federal action significantly affecting the quality of the human environment.
