See, for example, 43 USC §1715(a), which provides certain eminent domain authority for BLM and FS related to access to agency lands. 16 The authority of the federal land management agencies to condemn land has been the focus of provisions of annual appropriations laws for Interior, Environment, and Related Agencies. These provisions generally prohibit acquisition funds in those laws from being used to condemn land without the approval of the House and Senate Committees on Appropriations. See, for example, P.L. 117-328, Division G, Title IV, Section 409. See also CRS Report R46417, Congress’s Power Over Appropriations: Constitutional and Statutory Provisions, by Sean M. Stiff, at 37-38 (discussing the Department of Justice’s view that similar provisions requiring an agency to receive congressional committee approval before obligating funds may be unconstitutional).

Preservation of park units is a primary part of the NPS mission,36 and provisions of law limit the power of the Secretary of the Interior to dispose of land in changing park boundaries. Although the Secretary can, under specified conditions, make boundary changes that concurrently add and remove land within the boundary, minor boundary revisions solely to remove NPS acreage can be remove land within the boundary, minor boundary revisions solely to remove NPS acreage can be
made only by Congress. Also, the Secretary can acquire by exchange lands that are adjacent to a made only by Congress. Also, the Secretary can acquire by exchange lands that are adjacent to a
boundary revision, but the Secretary cannot dispose of NPS land to do boundary revision, but the Secretary cannot dispose of NPS land to do so (54 U.S.C. §100506(c)). Other provisions of law authorize the Secretary of the Interior to convey a “freehold or leasehold interest” in National Park System property under specified circumstances (54 U.S.C. §102901(a)). For instance, the property must have been acquired by the Secretary and must not be within a national park or national monument. In addition, the interest must be conditioned on the property being used in a manner “consistent with the purpose” of the park unit.37~~so (54 U.S.C. §100506(c)).~~
