October 2001 -3- 003-2182.004 <br /> unsuitable materials, and that the subgrade surface was compacted prior to <br /> Soil Liner Fill placement. <br /> ► Golder visually monitored the placement and compaction of Soil Liner Fill <br /> including observation of depth verification performed by Ames, particle <br /> size, moisture conditioning, and compaction of the fill. Golder performed <br /> in-place density and moisture content testing, and performed CQA <br /> laboratory testing of grain size, moisture content, Atterberg limits, <br /> compaction, and permeability. Golder also provided visual monitoring of <br /> the preparation of the Soil Liner Fill surface for geomembrane <br /> deployment, including verification that the surface was proof-rolled, <br /> compacted, and hand-worked so as to be free of desiccation cracks, abrupt <br /> grade changes, and sharp stones or objects. Golder also observed the <br /> backfill and compaction of the anchor trenches. <br /> ► Golder observed the installation of the Leak Detection Collection <br /> Recovery System (LDCRS), which includes the pipes and Leak Detection <br /> Fill. Golder visually verified that the sump was excavated to the minimum <br /> required dimensions, and the LDCRS pipes and fill were installed <br /> according to the plans. Golder performed CQA laboratory testing of grain <br /> size, Atterberg limits, and moisture content of the Leak Detection Fill <br /> placed in the Sump. <br /> ► Golder observed installation of Base Course over the geomembrane placed <br /> on the east bench. Golder performed CQA laboratory testing for grain size <br /> and Atterberg limits on Base Course placed. <br /> ► Golder monitored the ambient air temperatures and the temperature of all <br /> fills, including Soil Liner Fill, in accordance with project specifications. <br /> 1.2.2 CQA/CQC Monitoring of Geosynthetics Installation <br /> Golder provided CQC and CQA monitoring of geosynthetics used for the External Pond. CQC <br /> services provided by Golder consisted of performing geosynthetics inventory and checking <br /> quality control certifications prior to geosynthetics deployment. Golder performed <br /> geosynthetics CQA activities in accordance with the CQA Plan. Geosynthetics CQA activities <br /> performed included: <br /> I\00\2182TXMRNALPOND"WINALDOC Golder Associates <br />
