This figure has been <br />removed from the weekly reports. <br />D) Drain Cover Fill (DCF) <br />Drain cover fill (DCF) placement performed in the area shown on Figure 2. The DCF was hauled <br />from the processing area to the placement area using 40 -ton articulating haul trucks loaded by a <br />CAT 988 (250703) and a CAT 992 (250601) front -end loader. The DCF was placed in a 2 -foot lift <br />using various CAT dozers except where haul routes were established. Haul routes consisted of <br />four -foot lifts to be spread into 2 -foot lifts later. Laborers were present at all times during <br />placement removing debris /sandbags and assisting the dozer operator with lift thickness. All DCF <br />was placed on previously approved primary geomembrane. AMEC field representatives <br />monitored the DCF placement constantly. <br />Temperatures were monitored by an AMEC field representative prior to fill placement when <br />ambient temperatures were below 32 °F. Fill material was not placed until the entire fill area was at <br />or above 32 °F. Fill temperatures averaged between 35 °F and 44 °F <br />II) Geosynthetics <br />A) Geomembrane <br />No work performed during the week. <br />III) Storm Water Management <br />A) Best Management Practices (BMP) <br />Best Management Practices are being observed throughout the Mill Site Earthworks project. <br />IV) MSE Wall Construction <br />Wall #1 <br />Installation of wall components was performed for Mat's 1 and 2. An amec field representative <br />inspected and approved placed backfill materials, which was determined acceptable per the plans <br />and specifications to continue with the installation of the remaining wall components. <br />Wall #2 <br />MEW Weekly Report WE 12.01.2012.docx <br />
