The [Secretary](/usc/16/410r–5.md?p=c-1) of the Interior is authorized to accept from grantors title to non-[Federal land](/usc/16/3102.md?p=2) and interests in land, together with improvements thereon, situated within or adjacent to the Great Smoky Mountains National [Park](/usc/16/410r–5.md?p=c-3), and in exchange therefor, to convey by deed on behalf of the United States to the aforesaid grantors, land or interests therein, together with improvements thereon, situated within the Great Smoky Mountains National [Park](/usc/16/410r–5.md?p=c-3): Provided, That such exchanges may be made without additional compensation by either party to the exchange when the properties to be exchanged are of approximately equal value; however, when the properties are not of approximately equal value, as may be determined by the [Secretary](/usc/16/410r–5.md?p=c-1), an additional payment of funds shall be required by the [Secretary](/usc/16/410r–5.md?p=c-1) or by the grantor of non-Federal properties, as the case may be, in order to make an equal exchange, and the [Secretary](/usc/16/410r–5.md?p=c-1) is authorized to use any land [acquisition](/usc/16/620e.md?p=1) funds relating to the National [Park](/usc/16/410r–5.md?p=c-3) System for such purposes: Provided further, That not more than two hundred acres of [park](/usc/16/410r–5.md?p=c-3) land shall be conveyed pursuant to the aforesaid exchange authority. All properties acquired by the United States pursuant to this section shall become a part of the Great Smoky Mountain National [Park](/usc/16/410r–5.md?p=c-3) upon [acquisition](/usc/16/620e.md?p=1) thereof. Properties conveyed by the United States pursuant to this section shall thereafter be excluded from the [park](/usc/16/410r–5.md?p=c-3) and any Federal regulation or control thereof for [park](/usc/16/410r–5.md?p=c-3) purposes.
