A lessee may, with the approval of the Secretary, surrender a lease or any part of it, on the following conditions:
(b)
The superintendent, after consultation with the authorized officer, must be satisfied that proper provisions have been made for the conservation and protection of the property, and that all operations on the portion of the lease surrendered have been properly reclaimed, abandoned, or conditioned, as required;
(c)
If a lease has been recorded, the lessee must submit a release along with the recording information of the original lease so that, after acceptance of the release, it may be recorded;
(d)
If a lessee requests to surrender an entire lease or an entire undivided portion of a lease document, the lessee must deliver to the superintendent or area director the original lease documents; Provided, that where the request is made by an assignee to whom no copy of the lease was delivered, the assignee must deliver to the superintendent or area director only its copy of the assignment;
(e)
If the lease (or a portion thereof being surrendered) is owned in undivided interests, all lessees owning undivided interests in the lease must join in the request for surrender;
(f)
No part of any advance rental shall be refunded to the lessee, nor shall any subsequent surrender or termination of a lease relieve the lessee of the obligation to pay advance rental if advance rental became due prior to the date the request for surrender was received by the superintendent or area director;
(g)
If oil, gas, or geothermal resources are being drained from the leased premises by a well or wells located on lands not included in the lease, the Secretary reserves the right, prior to acceptance of the surrender, to impose reasonable and equitable terms and conditions to protect the interests of the Indian mineral owners of the lands surrendered. Such terms and conditions may include payment of compensatory royalty for any drainage; and
(h)
Upon expiration or surrender of a solid mineral lease the lessee shall deliver the leased premises in a condition conforming to the approved reclamation plan. Unless otherwise provided in the lease, the machinery necessary to operate the mine is the property of the lessee. However, the machinery may not be removed from the leased premises without the written permission of the Secretary.
