ameo�­, <br /> See the attached LVSCF map for all placement and accepted locations for primary geomembrane <br /> deployment. <br /> E) Drain Cover Fill (DCF): <br /> Cat 740 trucks hauled drain cover fill (DCF)to the PSSA. Haul roads for the Cat 740s were <br /> maintained at least 4 feet above the secondary geomembrane. <br /> Drain cover fill was placed on accepted primary liner in minimum 2-foot lifts in the PSSA on <br /> panels P20 to P22; P24 to P27; P31to P34; P67 to P68; P72 to P74; P77 to P79; P158 to P1�9; <br /> P161 to P163; P193 to P198; P219 to P224; P254 to P256; P260; P264; P266; 1285 to P286 <br /> and P288 to P290 <br /> Silt, mud, and deleterious material in the drain cover fill were removed from the from PSSA floor <br /> near the HVSCS header pipe. <br /> The DCF ramp on the north end of the PSSA floor was removed for subsequent primary liner tie <br /> in. <br /> F) High Volume Solution Collection System Piping (HVSCS): <br /> Four-inch and 12-inch ADS HVSCS piping was laid out on the on the PSSA inboard slopes. <br /> Ames performed 28-inch HDPE pipe perforation drilling at the Dump 4 pad; '/z-inch holes, 12 i ich <br /> spacing, 8 holes in the pipes circumference, as per project plans. After the pipes were performed <br /> they were transported to the PSSA ADR ramp. <br /> Fusion welding occurred on the HVSCS HDPE piping header in the PSSA sump. <br /> II) Storm Water Management <br /> Best Management Practices(BMPs) are being performed. <br /> CQA ACTIVITIES: <br /> 1) Field Activities: Field activities and observation during this reporting period included: Slope grading <br /> and fill placement; underground working remediation; geomembrane deployment, material sampling <br /> and testing, repair monitoring, and acceptance;; HVSCS HDPE piping perforation and fusion, ADS <br /> HVSCS piping layout; LVSCF acceptance for primary liner deployment; and DCF sampling. <br /> II) Laboratory Activities: Permeability, Atterberg limits, moisture, and sieve analysis laboratory testing <br /> continued. <br /> The following samples were collected and returned to AMEC's laboratory for analysis: <br /> Drain Cover Fill sample DCF 112(control sample) <br /> r Drain Cover Fill samples DCF 6-R (Record sample.) <br /> Concrete cylinders from the underground workings <br /> Geogrid samples were collected and sent to an off-site laboratory for analysis. <br /> 2014 10 04-MLE2 WEEKLY FINAL Pace 4 of 8 <br />
