Cameron SLF processing continued. <br /> Cat 777 haul trucks transported SLF to the ADR haul road between stations 16+00 to 22+00. Cat <br /> dozers placed SLF between stations 14+00 to 22+00. A Cat smooth drum roller compacted the <br /> SLF surface. <br /> Cat dozers placed SLF below stations DO+00 to D8+00 and F12+00 to F20+00. A Cat smooth <br /> drum roller compacted the SLF surface below stations F16+00 to F20+00. <br /> A Cat dozer placed SLF between stations FM8+00 to FM16+00 and HM10+00 to HM16+00. <br /> All of the above Soil Liner Fill material was placed, graded, and compacted 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 excavator prepared leak detection trench between stations FM6+00 to FM8+00.
