No additional areas of Subgrade were accepted during the reporting <br /> period. Figure 2 shows the current areas of accepted subgrade. <br /> 1.4 Soil Liner Fill <br /> SLF placement was performed in the areas shown on Figure 3. Subgrade was approved and <br /> moisture conditioned and compacted (when required) prior to SLF placement. SLF material was <br /> hauled to the Phase 2 VLF from the Dump 1 stockpile using articulating haul trucks. The <br /> material was then spread with low ground pressure CAT dozers equipped with GPS. Moisture <br /> conditioning of SLF material was performed in place using a water truck, and compaction was <br /> achieved using a 19-ton vibratory smooth drum compactor. Moisture content verification, <br /> nuclear density testing, and depth verification were performed, with results meeting the <br /> required project technical specifications, prior to accepting the surface for geomembrane <br /> installation. All test locations were surveyed. <br /> SLF processing continued at the Dump 1 processing plant. <br /> 1.5 Leak Detection Trench <br /> The leak detection trench connecting the existing Phase 1 trench with the Phase 2A trench was <br /> constructed and completed in accordance with project drawings and technical specifications. <br /> NewFields personnel monitored all leak detection trench construction activity. <br /> 2.0 GEOSYNTHETICS <br /> 2.1 Geomembrane Installation <br /> Geomembrane installation continued within the Phase 2A limits shown on Figure 4. <br /> Approximately 192,671 square feet (P-2546 to P-2603) of 80-mil LLDPE (double sided texture) <br /> was deployed. Subgrade was inspected and approved by NewFields, Tezak, Newmont, and <br /> Page 2 <br />
