amec�� <br />approximately 24 inch lifts. The lifts were compacted per method specification by a Cat CS56 smooth drum <br />vibratory roller. <br />A John Deere 850 excavator loaded 740 haul trucks with material removed at the base of the PSSA toe berm. The <br />material was hauled to the upper PSSA toe berm fill surface and was placed using a Cat D8 GPS dozer in <br />approximately 24 inch lifts. The lifts were compacted per method specification by a Cat CS56 smooth drum <br />vibratory roller. <br />A John Deere 1050J, a Cat D8t GPS, and a Cat D6 GPS dozer graded the slopes between stations HHO +00 to <br />HH2 +00 and FF4 +00 to FF8 +00. <br />A Cat D9 dozer removed the former highway pavement and prepared a drill pad below the Crib Wall near stations <br />B8 +00 to B10 +00. <br />A Cat dozer graded the slope near stations Q6 +00 to 010 +00. <br />Clay (SLF) Processing: <br />Cameron Site: No clay mining or processing occurred at the Cameron Site. Approximately, 244,860 tons of clay / <br />soil liner fill (SLF) material have been produced at the Cameron site. SLF produced from the operation remains <br />stockpiled at Cameron Site for later removal I use. <br />Squaw Gulch Clay Borrow Site: Clay processing took place at the Squaw Gulch Clay Borrow Site. <br />Approximately, 41,500 tons of soil liner fill material has been produced at the Squaw Gulch Clay Borrow Site to <br />date. <br />A Cat 980 loader was used to transport till from the mid portion of the clay borrow area to the lower portion for <br />processing. <br />Underdrain System: <br />Secondary Underdrain: No secondary underdrain was installed during this reporting period.

Work is to continue. <br />Working UG #6302 was excavated to a depth of 25 feet. The bottom of the shaft was not located and no timbers <br />were found, they were possibly removed during slope grading. What appears to be an alit was noted at the bottom <br />of the excavation trending in a northerly direction up- slope. Drilling will be required to further locate the adit. The <br />shaft was backfilled for safety and drilling access was provided. Work to continue. <br />Cemented rock fill was placed in Underground Working number 6087. <br />UG 6374 was prepped for a 2 -layer geogrid system.
