Texas Natural Resources Code - NAT RES § 131.202. Amount of Performance Bond

(a) The amount of the bond required for each bonded area depends on the reclamation requirements of the approved permit and shall be determined by the commission.

(b) The commission's determination shall be based on two estimates, one of which shall be submitted by the permit applicant and the other prepared by the commission under procedures established by rule. Only the commission's estimate will be considered if the applicant waives the right to submit an estimate.

(c) The amount of the bond shall be determined by the commission and shall be sufficient to assure the completion of the reclamation plan if the work had to be performed by a third party in the event of forfeiture.
