ame& <br />A Cat 966 loader placed processed undersized rip rap material from the riprap plant in Cat 740 <br />haul trucks. This material was hauled and placed into underground working #6446. <br />Rip rap was loaded into Cat 740 haul trucks from the rip rap plant and transported to the Phase 2 <br />diversion channel. Geotextile fabric and rip rap were placed on top of approved subgrade by a <br />Cat excavator from STA 16 +00 to 18 +00. <br />Cat dozers were finish grading and contouring the Phase 1 diversion channel. A Cat vibratory <br />roller compacted the subgrade according to project specifications. <br />Cat dozers were finish grading between Bench D and Bench F. A Cat vibratory roller compacted <br />the subgrade according to project specifications. <br />A Cat 330 excavator and a Cat 312 excavator hammered oversized rock on the northern slope of <br />the PSSA. <br />Subgrade slope finishing and contouring occurred at various locations below elevation 9,450 on <br />the PSSA slopes. Excess cut was stockpiled at the toe of the slope for later removal. <br />A Cat smooth drum roller compacted subgrade in various areas within PSSA and surrounding <br />Phase 1 slopes. <br />A Cat excavator continued anchor trench excavation on the 9,450 elevation above the ADR <br />Platform. <br />Subgrade: <br />The following subgrade areas in the PSSA were compacted per project specification to finished <br />grade, inspected and certified for soil liner fill (SLF) placement: <br />From the A Bench (9,450 elevation) to the PSSA floor between approximate stations <br />Al2 +00 to A18 +00 <br />> From the B Bench (9,450 elevation) to the PSSA floor between approximate stations <br />B8 +00 to B12 +00 <br />See the attached subgrade acceptance map for all accepted subgrade locations. <br />Soil Liner Fill (SLF): <br />SLF was placed and compacted per project specification; then, inspected, tested and certified in <br />compliance with technical specifications in the following areas: <br />From STA A6 +00 to A10 +00 and downslope to the PSSA floor. <br />From STA B5 +00 to B9 +00 and downslope to the PSSA floor. <br />Portions of the south and southwestern PSSA floor <br />See the attached SLF acceptance map for all accepted locations. <br />SLF from the Squaw Gulch stockpile was hauled to northern and southern inboard slopes and to <br />the PSSA floor. The material was placed on the approved slope subgrade as fill and also <br />stockpiled on the PSSA floor for later use in the area. <br />SLF was placed in a loose lift approximately 1.5 feet thick on the approved subgrade by Cat GPS <br />dozers and 740 Haul Trucks. <br />SLF finishing and contouring occurred on the SLF at the PSSA North and South slopes. <br />Density tests, N -45 to N -71, and depth checks, D -21 to D -39, were performed. <br />2014.06.28 -mle2 weekly final Page 2 of 7 <br />
