encounter groundwater and is developed by air-rotaiy methods will be abandoned by backfilling_ <br /> the hole with dry drill cuttings and installing a manufactured plug approximately 5 feet below the <br /> surface. The top 5 feet will be filled with surrounding surficial materials. <br /> 5. Describe how portals,adits,shafts,ponds,excavations,or other disturbance will be reclaimed <br /> (refer to Rule 3 and Rule 5 for specific reclamation performance standards).You may wish to <br /> contact the Division for closure specifications. <br /> Drill pads will be graded to their original contours,topsoil will be distributed,and the disturbance <br /> area will be seeded. Mud pits will be used to manage and contain the circulating drilling mud. <br /> The sump/mud pit will be excavated within the footprint of the drill pad,with the excavated spoils <br /> contained within the drill pad footprint as well. The excavated spoils will be isolated and clearly <br /> differentiated from the topsoil stockpile. Following completion of the drilling,the sump pits will <br /> be backfilled using the excavated spoils and drill cuttings and returned to the original site grade. <br /> Topsoil will be redistributed over the disturbance and the sites will be seeded. <br /> 6. Describe how roads will be reclaimed or returned to their pre-prospecting(or better)condition: <br /> All drill pads and offroad access trails will be reclaimed. Ripping or scarification of compacted <br /> soils will be performed if necessary. All disturbed roads and pads will be contoured to promote <br /> positive drainage and blend in with the surrounding terrain. Disturbances related to off road <br /> access or drilling operations will be seeded to promote native vegetation growth. <br /> 7. List the seed mixture to be used in the re-establishment of vegetation. See attached seed mixture <br /> calculation to obtain PLS/acre. For assistance with formulating seed mixtures and rates,contact <br /> the local NRCS if on private land,BLM/USFS if on public land or State Land Board if on state <br /> land. <br /> a.
