Geotechnical coring of weathered soils <br />p� <br />will provide supporting information to <br />better evaluate the suitability and <br />✓- <br />limitations of a future refuse disposal <br />area. Fourteen coring locations are <br />G <br />shown along with anticipated overland <br />travel access routes. When available, <br />�7inta / <br />be following <br />GT_F <br />we will old exploration <br />routes to the extent possible. Minimal <br />Q <br />v <br />ygq <br />GT' <br />_ <br />disturbance will occur with cuttings <br />from each hole being backfilled shortly <br />after the coring is completed. <br />f <br />Coring will be accomplished with a light <br />A <br />\\\ <br />A <br />truck mounted coring rig. Depth of <br />each core will be determined by the soil <br />depth with 60 feet being the deepest <br />anticipated depth with an expected <br />b <br />average of around 30 feet. <br />8) <br />f <br />_ <br />b <br />Holes will be plugged in accordance <br />with Rule 4.07.3 by backfilling the lower <br />f G <br />p <br />section with cuttings.
