has a uniform one foot of topsoil and 2.5 feet of overburden across all areas. Sand volumes <br /> were not calculated as detailed information on their location and thickness were not obtained. <br /> No sand volume is assumed for the reclamation volume balance calculations, however, sand is <br /> very likely to be encountered. Any sand encountered will either be sold or used to augment the <br /> overburden for backfill. Topsoil will be replaced in an average two-foot layer across all non-pond <br /> disturbances, while overburden and other excess material will be used to backfill the pit slopes <br /> from 1.5H:1 V to 3H:1 V. <br /> Table E-2 Reclamation Volumes <br /> Material Available on Site Requirements for Reclamation <br /> Reclamation Area Area Topsoil Overburden Topsoil Overburden Backfill <br /> Stripped Required <br /> (acres) (CY) Stripped(CY) (C9 Required(CY) <br /> Mining Area& 32.2 51,870 129,680 30,300 109,278 <br /> Surroundings <br /> Excess material will be used for backfilling slopes. Sand that may be encountered will be used <br /> for backfilling or will be sold. Asphalt Specialties will keep the minimum amount of material <br /> (topsoil, overburden, and potentially sand) required for reclamation throughout the entire mine <br /> life. <br /> Based on market demand, a portion or all of the area within the slurry wall may be backfilled. If <br /> the site is completely or partially backfilled the amount of area reclaimed as dry rangeland will <br /> increase. The operator will ensure that material is clean and uncontaminated. They will utilize <br /> the same forms as the Chavers Resource because the Chavers resource will act as the <br /> processing and sales point for the Marcovich site. <br /> 2. Topsoil Replacement <br /> An average of one foot of topsoil will be stripped and stockpiled prior to mining. After backfilling <br /> and grading has been completed during reclamation, topsoil will be replaced at 0.5 to 1.5 feet, <br /> at an average depth of one foot in a manner that is similar to the pre-mine soil profile. Topsoil <br /> will only be placed on the pond slopes and other surrounding disturbances. Topsoil will not be <br /> replaced on the pond floors. Replaced topsoil will be directly placed by loaders and haul trucks. <br /> All topsoiled areas will be disced to aid in root penetration. <br /> 3. Haul Roads and Access <br /> All internal haul roads will remain following reclamation to support the future land use. <br /> Marcovich Gravel Pit <br /> May 2024 E-2 11111 Lewicki&Associates <br />
