4. Topsoil and Overburden Handling <br /> Topsoil averages 0.5-1.5 feet, averaging 1 foot, overlying 2.5 feet of overburden. Topsoil and <br /> overburden will be stripped with appropriate earthmoving equipment as deemed suitable for the <br /> operation such as front-end loaders, dozers, excavators, and water trucks. Topsoil and <br /> overburden will be stockpiled separately onsite in either designated stockpiles, berms, or <br /> directly placed to create final reclamation slopes. Stockpiles must be below the elevation of the <br /> baseline conditions because the site is nearly entirely within the floodplain. The very first portion <br /> of stripping will be hauled from Marcovich to Chavers. After that stripped materials will be <br /> directly placed into reclamation or stockpiled on the pit floor. These materials will be directly <br /> placed in the designated stockpile areas or berms which can be seen on Map C-3. Stockpiles to <br /> be in place longer than 90 days will be seeded with the permanent seed mix to prevent erosion <br /> (see Exhibit E for seed mix). An average of one feet of topsoil and 2.5 feet of overburden were <br /> assumed to determine the overall material balance shown in Table D-2. <br /> Table D-2 Topsoil and Overburden Material Generated During Mining <br /> Stripping Area(ac) Material Generated (CY) <br /> Topsoil 32.1 51,870 <br /> ---------------- <br /> Overburden 32.1 129,680 <br /> Due to the reclaimed land use as water storage ponds, there will be an excess of topsoil than <br /> what is needed for reclamation. This is because the pond makes up the majority of the <br /> reclaimed land and does not need to be topsoiled entirely. There is not enough overburden to <br /> meet reclamation needs by itself, however, with excess topsoil and potential sand, there is more <br /> than enough material on site for reclamation. Excess topsoil and overburden will be used to <br /> achieve the final grading shown in the reclamation map in Exhibit F. Overburden, topsoil, and <br /> sand will be used to backfill mining slopes to their final reclaimed state. Topsoil will be replaced <br /> on all disturbances outside of the ponds and on the pond slopes. It will not be replaced on the <br /> pond floor. Topsoil will be replaced in an average two-foot layer to restore the existing soil <br /> conditions. Details pertaining to reclamation can be found in Exhibit E and the maps in Exhibit F. <br /> 5. Site Access <br /> The Marcovich Mining Resource will be accessed via two easements to cross agricultural land <br /> to the active Chavers Mining Resource. A 40-foot wide easement has been granted to the <br /> operator. A two lane graveled road will be constructed. This road will remain in place after <br /> mining is completed. Easements are shown on map C-1. <br /> Marcovich Gravel Pit <br /> May 2024 D-3 Lewicki& Associates <br />
