49 CFR 29.522: If a compact or funding agreement (or portion thereof) is retroceded, reassumed, terminated, or expires, may the Department reacquire title to property purchased with funds under any compact and funding agreement or excess or surplus Federal property that was donated to the Tribe under the Program?

If a compact or funding agreement (or portion thereof) is retroceded, reassumed, terminated, or expires, the Tribe retains title to the property purchased with funds under any compact and funding agreement or excess or surplus Federal property donated under the Program if it is valued at $5,000 or less. If the value of the property is over $5,000 at the time of retrocession, withdrawal, or reassumption, title to such property may revert to the Department at the Department's discretion.
