ame0 <br />density testing, moisture verification, and depth check testing was performed with results <br />within project specifications. Test locations were surveyed by Ames. <br />D) High Volume Solution Collection System <br />1) High Volume Solution Collection Piping <br />Placement of the high volume collection system continued at the DCF placement area shown <br />on Figure 5A and Figure 5B, advancing in front of the placement. CPeP was placed and <br />sandbagged in accordance with design drawings and project specifications. <br />2) Drain Cover Fill (DCF) <br />Drain cover fill (DCF) placement within the Phase 5 VLF continued. DCF was placed in the <br />areas shown on Figure 5A and Figure 5B. The DCF was hauled from the processing area to the <br />placement area using 40 -ton articulating haul trucks. The DCF was placed in a 2 -foot lift using <br />various CAT dozers except where haul routes were established. Haul route consisted of five - <br />foot lifts to be spread into 2 -foot lifts later. Laborers were present at all times during placement <br />holding the high volume collection piping in place, removing debris /sandbags, and assisting <br />the dozer operator with lift thickness. All DCF was placed on previously approved primary <br />geomembrane. AMEC field representatives monitored the DCF placement constantly. <br />E) Leak Detection Trench <br />1) VLF <br />A portion of the leak detection system was installed between stations J23 +00 ( + / -) and J30 +20 <br />( + / -), approximately 10 to 50 feet left of centerline. The 1'xl' trench was excavated using a <br />CAT 312 excavator. 40mil HDPE geomembrane and 12oz /ft geotextile were placed in the <br />trench. Three -inch CPe pipe was then placed over the geotextile. Approved leak detection fill <br />(LDF) was placed in the trench using a skid steer loader and laborers. The geotextile was <br />wrapped and overlapped, encapsulating the LDF and 3" CPe pipe. SLF material was then <br />placed over the trench. Leak detection trench construction was observed and inspected by an <br />AMEC field representative and found to be constructed in accordance with design drawing and <br />project specifications. <br />The leak detection was placed under the anchor trench near station A 10+00 ( + / -). A SLF plug <br />was placed under the anchor trench encapsulating a 3" SDR 13.5 solid HDPE pipe. The <br />transition between CPeP and solid pipe was performed using a 3" split coupler and "burrito <br />wrapping" the geotextile, terminating it at the SLF plug. <br />II) Storm Water Management <br />A) Best Management Practices <br />Best Management Practices are being observed throughout the Phase 5 VLF Project. <br />VLF Weekly Report WE 10.01.2011 <br />
