Sec. 227.28  Cancellations.

    Leases shall be irrevocable except for breach of the terms and 
conditions of the same and may be forfeited and cancelled by an 
appropriate proceeding in the U.S. District Court for the District of 
Wyoming whenever the lessee fails to comply with their terms and 
conditions; the lessee may, on approval of the Secretary of the 
Interior, surrender a lease or any part of it:
    (a) That he make application for cancellation to the superintendent 
having jurisdiction over the land.
    (b) That he pay a surrender fee of $1 at the time the application is 
made.
    (c) That he pay all royalties and rentals due to the date of such 
application.
    (d) That he make a satisfactory showing that full provision has been 
made for conservation and protection of the property and that all wells, 
drilled on the portion of the lease surrendered, have been properly 
abandoned.
    (e) If the lease has been recorded, that he file, with his 
application, a recorded release of the acreage covered by the 
application.
    (f) If the application is for the cancellation of the entire lease 
or the entire undivided portion, that he surrender the lease: Provided, 
That where the application is made by an assignee to whom no copy of the 
lease was delivered, he will be required to surrender only his copy of 
the assignment.
    (g) If the lease (or portion being surrendered or canceled) is owned 
in undivided interests by more than one party, then all parties shall 
join in the application for cancellation.
    (h) That all required fees and papers must be in the mail or 
received on or before the date upon which rents and royalties become 
due, in order for the lessee and his surety to be relieved from 
liability for the payment of such royalties and rentals.
    (i) In the event oil or gas is being drained from the leased 
premises by wells not covered by the lease; the lease, or any part of it 
may be surrendered, only on such terms and conditions as the Secretary 
of the Interior may determine to be reasonable and equitable.
