<br />HHSPONSH: <br />The requested information is contained in revised Section <br />2.05.6(3), Probable Hydrologic Consequences, under the heading <br />"Surface Water Hffecta". <br />2. The effect of mining operations on alluvial ground water quality <br />downstream from the mine site in terms of an anticipated change in the <br />TDS concentration of the shallow ground water. <br />RESPONSH: <br />The requested information is contained in revised Section ,~% <br />2.05.6(3), Probable Hydrologic Consequences, under the heading <br />"Ground Water Hffects". <br />Soils - Rules 2.04.9, 2.05.3(5), 2.05.4(2)(d), and 4.06 <br />1. All soils information is based on an SCS Order III Soil Survey. <br />Given that the majority of the area is already disCurbed, and the only <br />new disturbance is approximately 5 acres, this will be adequate. <br />However, there is a problem with the amount of soil available for <br />reclamation. The only reference that could be found for replacement <br />depths was a tabulation on page 2.05-44. Using these figures and <br />comparing them with the amount of material available (Map No. 15, Topsoil <br />Redistribution), it appears there is a topsoil deficit in excess of <br />100,000 yd3. (See worksheet below.) This translates into a lack of <br />enough material to cover 34 acres to an average 2 foot depth. <br />-21- <br />
