Interpretive report submitted to the Office for approval prior to <br />placement of the material. <br />Prior to commencement of the rinsing operation, CC&VG must submit a plan for dealing <br />with the rinse solutions. Note: "Rinsing" of the Ironclad tailings is not proposed, rather <br />the tailings will be amended with Calcium Hypochlorite. <br />Geochemical Analysis of the Pit Floor: <br />Prior to the commencement of mining in the sulfide bearing areas, geochemical analyses <br />of the pit floor must be completed and an interpretation report submitted to the Division <br />for approval prior to mining. <br />Completion of Lone-Term Leaching Tests: <br />Prior to placement of ore or waste rock, CC&VG must complete the long-term leaching <br />tests of ore and waste rocks and provide an interpretative report to the Division. The <br />report must be approved by the Division prior to placement of ore and waste rocks. <br />SUMMARY OF COMMENTS FROM ALLEN SORENSON: <br />Items that will be inspected one time during construction: <br />- Leachate collection riser pipes; and, <br />- Vibrating wire piezometers. <br />Items that will be inspected several times during construction: <br />- Tce fill berm foundation area; <br />- Leach facility foundation preparation; <br />- Underdrain installation and material testing documentation; <br />- Leak detection trenches and sumps; <br />- Tce berm fill; <br />- Soil liner fill; <br />
