"Wil ='% <br />compactor, passing over the entire fill surface at least 4 times (method compaction technique was <br />applicable). An AMEC field representative observed the remediation of the underground working. <br />Underground Working #4087 was investigated using a CAT 330 excavator and observation was <br />performed by an AMEC field representative. Excavation of the area was performed and it was <br />found to be a shallow surface working. The native material was found to be consistent and all <br />signs of a significant working were removed. The working was backfilled by placing small lifts and <br />bucket tamping until access for a CAT 563 vibratory smooth drum compactor was achieved. The <br />material was then placed in 18" to 24" lifts. Each lift was moisture conditioned using a tandem <br />axle water truck (when necessary) and compacted using a 10 -ton vibratory smooth drum <br />compactor, passing over the entire fill surface at least 4 times (method compaction technique was <br />applicable).

There is a shaft present in <br />the working and a concrete plug will be placed in the working. Confirmatory drilling will be <br />performed when a drill rig is available. <br />D) Structures <br />No work performed during the week. <br />III) Geosynthetics <br />A) Geomembrane Installation <br />No work performed during the week. <br />B) Anchor Trench <br />No work performed during the week. <br />Q Geomembrane Exposure <br />No work performed during the week. <br />D) Geomembrane Acceptance <br />No work performed during the week. <br />IV)Storm Water Management <br />A) Best Management Practices (BMP) <br />Best Management Practices are being observed throughout the Mill Site Earthworks project. <br />MEW Weekly Report WE 05.05.2012 <br />
