Upon satisfaction of the requirements for which the bond was security, or upon expiration, termination, or cancellation of the right-of-way, the grantee may ask BIA in writing to release all or part of the bond or alternative form of security and release the grantee from the obligation to maintain insurance. Upon receiving the grantee's request, BIA will:
(a) Confirm with the tribe, for tribal land or, where feasible, with the Indian landowners for individually owned Indian land, that the grantee has complied with all applicable grant obligations; and
(b) Release all or part of the bond or alternative form of security to the grantee, unless we determine that the bond or security must be redeemed to fulfill the contractual obligations.
