Aft <br />A John Deere 870 excavator, a Cat D8 dozer and Cat 740 haul trucks removed shot rock from behind the historic <br />crib wall. The shot rock was placed as structural fill at the ADR Haul road near stations 21 +00 to 22+00. The <br />structural fill was placed and compacted per method specification. <br />A Cat D8 GPS dozer was used to cut material from the slope for use as structural fill near station E2 +00 to E6 +00. <br />The material was placed in approximately 36 inch lifts. The structural fill was placed and compacted per method <br />specification. <br />Cat D10 dozers and a D8 GPS dozer rough graded the slope near stations C1+00 to C4 +00 and pushed material <br />down slope. <br />A Cat D10 dozer and a D8 GPS dozer rough graded the slope near stations P4+00 to P6+00 and pushed material <br />down slope. <br />Note: An Amec field representative monitored structural fill material temperatures placed within the areas of fill <br />during all shifts. Average structural fill temperatures were above 32 °F. <br />Clay (SLF) Processing: <br />Cameron Site: No clay mining or processing occurred at the Cameron Site. Approximately, 244,860 tons of clay l <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 / use. <br />Squaw Gulch Clay Borrow Site: Clay mining and processing took place at the Squaw Gulch Clay Borrow Site. <br />Approximately, 53,600 tons of soil liner fill material has been produced at the Squaw Gulch Clay Borrow Site to <br />date. <br />Underdrain System: <br />Secondary Underdrain: Approximately 70 feet of secondary underdrain was installed near station A6 +00. <br />Approximately, 5,134 feet of secondary underdrain has been completed to date in the VLF. <br />Primary Underdrain: Approximately, 180 lineal feet of the primary underdrain alignment was installed in the <br />bottom of the PSSA. <br />To date, a total of 1,474.60 feet of primary underdrain has been completed. <br />Tree /Slash Grubbing and Clearing Chipping: <br />Tree removal occurred near stations C1+00 to C4+00. <br />H) Underground Workings <br />Confirmation drilling and occurred at underground working U6428. Additional remediation work will be required. <br />Confirmation drilling and blasting occurred at underground working UG #6302 and UG #6003. Additional <br />remediation work will be required. <br />The third layer of geogrid and select structural fill were finished at Working UG # 6123. The site is considered <br />remediated. <br />C) Historical Crib Wall 1 South MSE Wall: <br />A Cat 320 excavator was used to remove tailings from behind the timbers at the historic crib wall. The tailings were <br />pushed down hill near station B16+00 where they were loaded out and used as fill. A Cat 320 excavator was also <br />1'ae 2 of 6 MLE2 WE 08Feb14.doc <br />
