16 U.S.C. § 430g–5 — Acquisition and disposal of lands

(a) General authority. (1) The Secretary may acquire land and land interests within the park by donation, by purchase with donated or appropriated funds, by exchange, or otherwise. (2) When acquiring land under sections 430g–4 through 430g–10, the Secretary must get only the minimum federal interest needed to meet the goals for each area and for the park as a whole. (3) Despite (1), the properties added to the park by section 430g–4(b)(2) may be acquired only through donation. (b) Authority to convey freehold and leasehold interests within park. The Secretary may convey land and land interests within the park under section 102901(a) of title 54. Even though that law normally limits how proceeds may be used, here the net proceeds from such a conveyance may — subject to appropriations — be used to buy land and interests within the park. (c) Conveyance of lands excluded from park. (1) The Secretary may exchange federal land excluded from the park under section 430g–4(c) for land within the park's boundary, following existing law. (2) If any such federal land is not exchanged within five years after August 17, 1990, the Secretary may sell it to the highest bidder under regulations the Secretary sets, but never for less than the land's fair market value as the Secretary determines it. (3) Any land sold or exchanged this way must carry terms and conditions the Secretary judges will protect the park and the Gettysburg Battlefield Historic District. Regardless of any other law, the net proceeds from such a sale or exchange must — subject to appropriations — go toward buying land and interests within the park. (d) Relinquishment of legislative jurisdiction to Pennsylvania. For land excluded from the park under section 430g–4(c) where the United States has exclusive or shared legal authority, the Secretary may give that authority back to Pennsylvania. This is done by filing a notice with the Governor; it takes effect once Pennsylvania accepts it, unless state law says otherwise.
