Tenn. Code § 59-8-210
Within such time as the commissioner shall prescribe, the operator shall file with the commissioner an annual report and map under each permit, stating the number of acres of land affected by the operation, the extent of reclamation and revegetation accomplished by the operator, and such other information as the commissioner may reasonably require in carrying out the provisions of this part. If the report and the commissioner's inspection of the area affected show that the operator has complied fully with this part, the commissioner shall approve the report and shall release the operator's bond, or the remainder thereof if any portion has already been released under other provisions of this part. If the commissioner does not approve the report, the bond shall not be released until the operator corrects the deficiencies found by the commissioner.
