This bill facilitates the exchange of administrative jurisdiction over specific federal land parcels located in Harpers Ferry, West Virginia, between the Department of the Interior and U.S. Customs and Border Protection. Its primary goal is to optimize land use by aligning parcels with their intended administrative functions without monetary reimbursement. The legislation transfers approximately 25 acres from the **Secretary of the Interior** to the **Commissioner of U.S. Customs and Border Protection** for use by the Advanced Training Center, requiring the exclusion of this land from the Harpers Ferry National Historical Park. Concurrently, about 71.51 acres are transferred from the Commissioner to the Secretary of the Interior, which will then be administered as part of the **Harpers Ferry National Historical Park**, with its boundaries adjusted accordingly. A key provision includes a **reversion clause**, ensuring that if the land transferred to CBP is no longer needed for the training center, its jurisdiction will revert to the Secretary of the Interior and be incorporated into the Park. The bill also mandates a land survey for the parcel transferred to CBP and exempts these transfers from existing acreage limitations for the Park.
