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. Larger <br />size gravels are removed from the plant by the stacker conveyors shown on Maps C -2 and C -4. A 24" <br />diameter fine slurry pipe discharges all fines into Pond #1. Pond #1, then overflows into Pond #2 and <br />then to Ponds #3 and #4. <br />Ponds #1 and #2 trap the larger material in the slurry which is excavated using track hoes and allowed <br />to dewater on the bank. After it is sufficiently dewatered, it is moved to the Topsoil Fines Piles #1 and <br />#2, which are shown on Maps C -2 and C -4. This material will be amended later and used as substitute <br />topsoil since most of the disturbance on site is pre -law and no topsoil was ever salvaged. <br />Also, since the plant produces large quantities of slurry, site personnel have been trained to frequently <br />pump the fine slurry from Ponds #3 and #4. A new floating dredge has been purchased in the 4th quarter <br />of 2014 and installed for this purpose. The dredge pumps the slurry to the older gravel mine area of the <br />permit, which is north of the gold plant. It is allowed to dewater in the designated area shown and then <br />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 from <br />the north disturbed area. Any overflow from Pond #4 goes into the overflow culvert underneath Access <br />#1 and then to Ponds E, F, G and H, as well as a number of smaller ponds and depressions which prevent <br />runoff from leaving the site. For these reasons, the site contains well above the 100 year 24 hour storm <br />runoff. Once mining progresses into the area south of Access #1 to the point where these ponds are <br />removed, South Ponds #1, #2, #3 and #4 will be constructed. <br />The following calculations show that Ponds #3 and #4 north of Access #1 is adequate: <br />Alma Place Mine 01/15 17 <br />
