Tenn. Code § 60-1-705
Upon failure of any operator to perform site protection or reclamation activities, as required by this chapter, and notice of default, if the default is not cured within a reasonable time by the operator or the surety, if any, on the operator's bond, the board shall declare the bond forfeited, collect the bond and use the proceeds for the required site protection or reclamation work. The supervisor may contract with any person or public agency to perform the reclamation work. Any portion of the bond not thus expended shall be refunded to the operator or the operator's surety if the conditions of the bond are fully satisfied. If the conditions of the bond are not fully satisfied, because the bond is a blanket bond or otherwise, the unexpended proceeds shall be held or applied in a manner to secure the performance of the remaining obligations secured by the bond. If the bond is a blanket bond and the unexpended portion is less than is required for the remaining wells covered by the bond, a supplementary bond shall be required.
