25 CFR § 169.130 - Must a right-of-way grant address ownership of permanent improvements?
(a) A right-of-way grant must specify who will own any permanent improvements the grantee constructs during the grant term and may specify under what conditions, if any, permanent improvements the grantee constructs may be conveyed to the Indian landowners during the grant term. In addition, the grant may indicate whether each specific permanent improvement the grantee constructs will:
(2) Be removed within a time period specified in the grant, at the grantee's expense, with the premises to be restored as closely as possible to their condition before construction of the permanent improvements; or
(3) Be disposed of by other specified means.
(b) A grant that requires the grantee to remove the permanent improvements must also provide the Indian landowners with an option to take possession of and title to the permanent improvements if the improvements are not removed within the specified time period.
