There will be minor tree trimming for rig clearance. Water for drilling purposes will be hauled to work site from Del Valle Pumping Plant. A mini excavator will use a sheep’s foot roller attachment to compact and stabilize the erosion slopes using the water truck for dust and aid in soil compaction.
