(a) Auger mining shall be conducted so as to maximize the utilization and conservation of the coal in accordance with 4VAC25-130-816.59.

(b) Auger mining shall be planned and conducted to maximize recoverability of mineral reserves remaining after the operation and reclamation are complete.

(c) The permittee shall leave areas of undisturbed coal, as approved by the division, to provide access for future underground mining activities to coal reserves remaining after augering is completed, unless it is established that the coal reserves have been depleted or are so limited in thickness or extent that it will not be practicable to recover the remaining coal. This determination shall be made by the division upon presentation of appropriate technical evidence by the permittee.
