ameo <br />• <br />density values. The moisture-density testing frequency was approximately one test per <br />28,667 cubic yards. There is no testing frequency for moisture density of LVSCF. Nuclear <br />density tests performed for the LVSCF are summarized in Table 14. <br />4.2.9 Drain Cover Fill <br />AMEC provided visual monitoring of DCF placement. One AMEC monitor and at least two <br />Ames laborers were present monitoring each dozer, unless two dozers were within <br />approximately 50 feet of each other during DCF placement. AMEC verified that wrinkles in <br />the geomembrane did not fold over, that PVC grade markers were placed on a maximum <br />50-foot by 50-foot grid and at grade breaks, and that material in the fill was sutiable. AMEC <br />continuously inspected geomembrane during DCF placement, marked areas for repair, if <br />required, and verified that all repairs were completed. After final grading, AMEC monitored <br />removal of PVC grade markers. <br />0 4.2.10 Select Drain Cover Fill <br />AMEC provided visual monitoring of SDCF placement. One AMEC monitor and at least one <br />Ames representative was present monitoring each piece of equipment as it placed material <br />around the High Volume Solution Collection risers. AMEC verified a minimum area of 3 feet <br />was placed around the riser extents, that no damage was caused to the riser piping as <br />SDCF was placed, and that all material in the fill was suitable. AMEC continuously <br />inspected riser piping during SDCF placement, marked areas for repair, if required, and <br />verified that all repairs were completed. <br />4.2.11 Temperature Monitoring <br />AMEC monitored ambient air temperatures using a Davis Vantage Pro 2 data-logging <br />thermometer. Temperatures were measured every hour. The lowest and highest daily <br />temperatures are summarized in Table 2. <br /> <br />AMEC Earth & Environmental, Inc. <br />2000 S.
