® <br />Areas of DCF were as -built surveyed to confirm 2 -feet minimum coverage above primary <br />geomembrane between Bench A stations A0 +00 to A17 +00 to approximately 15 feet above the <br />PSSA floor. <br />See the attached DCF map for all placement. <br />E) High Volume Solution Collection System Piping (HVSCS): <br />Twenty- eight -inch HDPE piping was transported from the Surge area laydown to the PSSA floor. <br />Fusion welding continued on the HVSCS 28 -inch HDPE piping in the PSSA floor. <br />Twenty- eight -inch HDPE HVSCS piping was being fused on the PSSA floor and placed extending <br />the 28 -inch HVSCS primary piping from the HVSCS manifold onto the PSSA floor. <br />Level indicator piping was installed on the steel riser pipes. <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; nuclear density and moisture testing; HVSCS pipe fusion and layout; level <br />indicator piping installation on the southwest side of steel riser pipes; Phase 1 surface acceptance; <br />DCF, SLF, and SF sampling. <br />11) 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 115 (Control sample) <br />➢ Structural Fill sample SF 99 -R through SF 101 -R (Record sample) <br />➢ Soil Liner Fill samples SLF -157C through SLF -159C (Control sample from the Cameron Site) <br />2014 10- 25 -MLE2 WEEKLY FINAL Page 3 of 7 <br />
