(a) The authorized officer shall notify those leaseholders who have nationwide or statewide bonds at the time of issuance of this subpart of the requirement to secure a separate lease bond for each lease in the amount determined by the authorized officer to be proper and necessary.

(b)

(1) In setting or adjusting individual lease bond amounts, the authorized officer shall assure that the lease bond covers reclamation within a permit area where the Surface Mining Officer, because of the absence of a cooperative agreement governing Federal lands within that state, notifies the authorized officer that the lease bond should cover that reclamation.

(2) After consultation with the Surface Mining Officer, the authorized officer may release the amount of any outstanding bond which is related to, and is not necessary to secure, the performance of reclamation within a permit area.
