Figure 1. VLF2 ROM Area Overview <br /> 9,9w <br /> 9900 B <br /> 268 <br /> 9,850' 67KK <br /> 9900 A2 <br /> 842K ,w / <br /> 95K ROM <br /> 9900 <br /> 19 <br /> No <br /> 90850' <br /> MITI <br /> TR103 allows for ROM placement on the VLF, but restricts placement of material sized 3" or <br /> greater against DCF, when dumped from heights of 50' or more. Specifically, TR103 states: <br /> The lift height shall be a minimum of 20'and a maximum height of 100'for crushed ore <br /> and ROM with less than 3 inch maximum size rocks. <br /> The 100'maximum height was developed during the initial loading of the VLF1 pad to <br /> prevent the operators developing an excessive slope at angle of repose on the pad. The <br /> combination of the 100'lift heights and benches allows the operators to develop the overall <br /> slopes that are outlined below without additional reshaping. Additionally, keeping the <br /> maximum slope height limited to 100'with material less than 3 inches minimizes the initial <br /> loading stresses on the Drain Cover Fill(DCF). <br /> The 20'minimum lift height recommendation was developed to minimize the force <br /> transferred to the DCF and geomembrane from a loaded haul trucks. <br /> A photo of the placed material is shown in Figure 2. The photo is taken looking southwest from <br /> the—9880 elevation. The grey material toward the bottom of the photo is DCF; the lighter <br /> material above is the placed ROM and crushed leach ore. The vertical distance from the ROM <br /> resting against the DCF, to the crest of the lift is approximately 30'. <br />
