together. The entire area is very low in topsoil. As stated eazlier in this section, the total topsoil <br />I ~ overburden thickness above the gravel averages 1-3 feet thickness, trending towazd greater <br />thicknesses to the north. Estimated thicknesses of topsoil throughout the permit azea range from 0" to <br />up to 4 feet in small pockets. Overburden ranges from 0 feet to 6 feet at the northern limit of the <br />mining. <br />A topsoil stockpile was made on the southwest end of the pernrit area after initial mining in 1977. <br />This stockpile covers an azea of approximately 0.2 acres and contains approximately 1,800 cubic <br />yazds. This pile is shown as the Topsoil Stockpile on Map C-2. It will be temporarily seeded with a <br />dryland pasture mix within 6 months of stockpiling. <br />From the soil survey and from site inspection, it is apparent that much of the pinon juniper slope azea <br />will yield little salvageable soil but there aze areas where some soil is thick enough to salvage. The <br />topsoil will be used to restore the north cut face of the pit which will be a slope of 2H:1 V and will be <br />south-facing. The existing vegetation on this undisturbed slope is less than 10%. The overburden <br />will be used to reclaim the flatter areas that will be irrigated where the soil quality is not as critical <br />on the slope. <br />• <br /> <br />As Strip 1 was mined prior to 2006, topsoil was salvaged and placed on the mined out south facing <br />2H:1 V slope to a depth of approximately 9 inches, where it is most needed for reclamation. Very <br />little overburden was present, however, an amount less than 700 cubic yazds was added to the <br />overburden stockpile as shown on Map C-2. <br />Topsoil Calculations <br />a) Current Soil Stockpile: 1,800 cy <br />b) Mine Strip 2: 2.65 acres - It is expected that the salvageable soil in Strip 2 will average 3 inches, <br />therefore, 3 inches x 2.65 acres = 1068 cy will be salvaged. Since soil from Strip 1 was used to <br />reclaim the exposed portion ofthe south facing slope, the soil from Strip 2 will be added to the <br />stockpile for later reclamation of yet unmined portions of the south facing slope. The stockpile will <br />then contain 2868 cy. <br />c) Mine Strip 3:4.47 acres - It is expected that the salvageable soil in Strip 3 will average 3 inches, <br />therefore, 3 inches x 4.47 acres = 1802 cy will be salvaged.
