NRCS Soils Found at Revenue <br />There are four soil types identified by the Natural Resource Conservation Service (NRCS) on site. <br />They are identified in Table I -1 below. <br />Table E — Revenue Mine Soils <br />These soils were identified using the NRCS Web Soil Survey. The associated report can be found in <br />Appendix H. <br />2. Topsoil Stripping & Replacement <br />The vast majority of the Revenue Mine is existing disturbance from the historical mining activities <br />that have taken place there. No topsoil was ever salvaged from this past activity. Topsoil will be <br />stripped from any area where it is identified prior to using an area for mining activities. <br />Topsoil on site is available from 3 areas: <br />1- the low area where Sediment Pond 2 and Mine water Pond 3 will be located. This is estimated as <br />12 inches over 1.58 acres = 2,550 cy. <br />2- portions of the Atlas tailings /waste pile. This is estimated as 12 inches over 7.39 acres = 11,922 <br />cy. <br />3- small area above existing Revenue Pond where the Revenue Pile will be extended to the south. <br />This is estimated as 6 inches over 0.5 acres = 806 cy. <br />Therefore, the total salvageable volume of topsoil on site is expected to be 15,278 cy. <br />Revenue Mine August 2012 I - <br />
