washing operation. It is buried along most of the length after the tee. <br />A pump along the side of Ponds #3 and #4 are also installed which pump water into 12" PVC buried <br />pipes which join in a tee as shown on Map C -4 and enter the plant in the buried 12" PVC pipe. These <br />pumps provide a backup water source in case there is a water call on the rights in the River Point of <br />Diversion. <br />The plant uses water to wash the gravels and separate the heavier gold particles from the gravel. <br />Larger size gravels are removed from the plant by the stacker conveyors shown on Maps C -2 and C- <br />4. A 24" diameter fine slurry pipe discharges all fines into Pond #1. Pond #1, then overflows into <br />Pond #2 and then to Ponds #3 and #4. <br />Ponds #I and #2 trap the larger material in the slurry which is excavated using track hoes and <br />allowed to dewater on the bank. After it is sufficiently dewatered, it is moved to the Topsoil Fines <br />Piles #1 and #2, which are shown on Maps C -2 and C -4. This material will be amended later and <br />used as substitute topsoil since most of the disturbance on site is pre -law and no topsoil was ever <br />salvaged. <br />Also, since the plant produces large quantities of slurry, site personnel have been trained to <br />frequently pump the fine slurry from Ponds #3 and #4. A new floating dredge has been purchased in <br />the 4" quarter of 2014 and installed for this purpose. The dredge pumps the slurry to the older gravel <br />mine area of the permit, which is north of the gold plant. It is allowed to dewater in the designated <br />area shown and then it is stockpiled in the same two Fines Piles discussed above. <br />The following calculations show that Ponds #3 and #4 have substantial volume for trapping runoff <br />from the north disturbed area. Any overflow from Pond #4 goes into the overflow culvert underneath <br />Access #I and then to Ponds E, F, G and H, as well as a number of smaller ponds and depressions <br />which prevent runoff from leaving the site. For these reasons, the site contains well above the 100 <br />year 24 hour storm runoff. Once mining progresses into the area south of Access #1 to the point <br />where these ponds are removed, South Ponds #1, #2, #3 and #4 will be constructed. <br />Alma Placer 1115 19 <br />
