Section 2. Backfilling and trading <br />A) Placer Pit: The pit will be limited to a maximum of 20,000 cy for backfilling. <br />B) The Infiltration Pond and highwall will be limited to a maximum of 12,000 cy backfilling. A <br />fill pile of approximately 8,000 cy is located immediately south of the highwall and will be used <br />to backfill the pond with an extremely short downhill dozer push. This pile is seen on Map C -2. <br />C) Other backfilling on site of process ponds and general grading is limited to 16,000 cy. <br />The total backfilling and grading quantity is therefore 48,000 cy. <br />Although some minor locations will have slopes of approximately 2.5H:1 V, these areas (less <br />than 1.5 acres) replicate the original slopes of the land. The vast majority of the reclamation will <br />have slopes less than 5H:1 V. <br />Section 3. Topsoiling <br />There are 2 main topsoil stockpiles on site that were constructed when the site was initially dis- <br />turbed from the previous operator. These two piles contain approximately 9,100 cy of topsoil. <br />In addition to thee efforts, import of topsoil will be encouraged over the life of the mine. Good <br />topsoil will be placed in Stockpiles #1 and #2. Poorer material may be added to the Substitute <br />Subsoil Stockpile. <br />Since a total of 35.56 acres will require re- topsoiling, an average depth of 6 inches will require a <br />quantity of 28,685 cy. The current available amount in stockpiles is 9100 cy, and an additional <br />amount of 8 inches is available from 11.0 acres of land that has not yet been disturbed. This will <br />yield an additional 11,831 cy. Therefore the total soil available will be 20,931 cy. Therefore, im- <br />port of approximately 7753 cy will be needed to complete the reclamation over the life of the <br />mine. This should not be a problem. <br />For the worst case retoposiling effort, topsoil will be spread evenly over the worst case disturbed <br />area to a depth of 6 inches. Using the area of 21.13 acres, this is a volume of 17,044 cy. <br />The operation will attempt to import as much topsoil as possible to provide a greater thickness of <br />soil cover on the reclaimed lands, since there is a deficit from the pre -law disturbance when no <br />topsoil was salvaged. <br />Gloria Z Mine 2013 Amendment 24 <br />
