     (2) A lease not producing coal in commercial quantities at the end of the primary term must be terminated, unless the leased lands are described in a strip mine permit issued under 82-4-221 or in a mine-site location permit under 82-4-122 prior to the end of the primary term, and the lease may not be terminated so long as the lands are covered and described under valid permit.

     (b) "covered and described" under a valid permit or "described" in a strip mine or mine-site location permit means that the leased lands or a portion of the leased lands within or outside of the boundaries of the permit area are expected to be affected or disturbed at some point during the life of the permittee's strip-mining or underground-mining operation and are identified in the permittee's permit application.
