The material <br />was transported to the E Bench and DD Bench. Cat dozers placed the SLF between stations <br />DD8+00 to DD12+00 and FF2+00 to FF8+00. A Cat dozer and a Cat smooth drum roller <br />prepared SLF subgrade below stations F8+00 to F11+00. A Cat D8 dozer constructed an SLF <br />road between the E and G Benches. A Cat dozer placed SLF between stations E12+00 and <br />E15+00. <br />A Cat excavator scarified the compacted surface of SLF above station C16+00. A water truck <br />equipped with a fire hose was used for moisture conditioning. A Cat smooth drum roller <br />compacted the SLF per project plans and specifications. <br />All of the above Soil Liner Fill material was placed, compacted, and graded per the project plans <br />and specifications. Moisture content, density testing and depth verification were performed per <br />project specification prior to surface acceptance and geomembrane installation. <br />See attached figure for approved SLF. <br />Drain Cover Fill: <br />Cat 740 haul trucks transported DCF from the stockpile to Phase 1. Low ground pressure Cat <br />dozers placed DCF on approved geomembrane in Phase 1. <br />See attached figure for approved DCF. <br />Underdrain System: <br />Primary Underdrain: Complete. <br />Secondary Underdrain: None. <br />Tertiary Underdrain: None. <br />Leak Detection: <br />A Cat 35 excavator continued excavating leak detection trench between stations DMO+00 and <br />DM3+00.
