If the mud pit is lined with plastic liner material, the liner shall either be removed prior to addition of cement to the drilling mud and cuttings, or the sides of the liner shall be folded over the top of the drilling mud and cuttings prior to backfilling the pit.
NR 130.110(2)(b)
(b) Drilling mud and cuttings from drillholes that penetrate 50 feet or less of metallic sulfide-bearing rock may be disposed on site within the mud pit. Prior to in-place disposal of the drilling mud and cuttings, any free water from the mud pit shall be removed and reused or properly disposed of in accordance with state and federal law. The drilling mud and cuttings shall be mixed with bentonite, cement, or other clean fill and the pit shall be backfilled with native soils.

If the person fails to submit a replacement bond, the person may not engage in bulk sampling until the person submits a satisfactory replacement bond. Revocation or suspension of a surety's license does not relieve the bulk sampling licensee from any financial obligation to stabilize and revegetate the bulk sampling site in accordance with the approved bulk sampling plan.
NR 130.204(2)(b)3.
3. The department may require that the amount of the bond submitted under this paragraph be increased at any time if the department determines that it is unlikely that the bond would be adequate to fund the cost to this state of completing the revegetation plan.
