Two (2) Cat D10 dozers, a Cat 330 excavator and a Cat 330 hammer were working the %A slope. A John Deere <br />870 excavator removed material from the west side of the Y ::1 slope. This material was transported using Cat 740 <br />haul trucks for placement as structural fill on the PSSA embankment. The structural fill was placed and compacted <br />per method specification. <br />Cat dozers cut the slope to rough grade near between stations A16 +00 to A19 +00, B12 +00 to B15 +00 and <br />D016 +00 to DD19 +00. <br />A Cat D10 dozer and a Cat 330 hammer cut the PSSA pond floor to grade. A John Deere 870 excavator loaded <br />740 haul trucks with structural fill material from the PSSA pond floor. The material was transported to PSSA <br />embankment fill. The structural fill was placed and compacted per method specification. <br />Note: An AMEC field professional monitored structural fill material temperatures placed within fill areas. Average <br />structural fill temperatures were above 32 °F. <br />Clay (61-9 Processing: <br />Cameron Site: No clay mining or processing occurred at the Cameron Site. Approximately, 244,860 tons of clay 1 <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 future use. <br />Squaw Gulch Clay Borrow Site: Clay mining and processing took place at the Squaw Gulch Clay Borrow Site. <br />Approximately, 100,541 tons of soil liner fill material has been produced at the Squaw Gulch Gay Borrow Site to <br />date. <br />Underdrain System: <br />Primary Underdrain: No work occurred on the primary underdrain. <br />Secondary Underdrain: No work occurred on the secondary underdrain. <br />Tree /Slash Grubbing and Clearing Chipping: <br />No clearing or grubbing occurred. <br />B) underground Workings <br />UG#6153: (UG #5012) Known surface working. <br />The working was excavated to competent rock. Backfilled with onsite structural fill in 12 -18 inch loose Nits. Each lift <br />was compacted using the excavator bucket to practical refusal. Site remediated. <br />1 Cat 330 excavator =1.5 hours TO <br />UG#6428: Unknown adit. <br />Previously shot rock removed using Cat excavators. Not complete; remediation efforts to be continued. <br />n) Storrs Water Management <br />Best Management Practices (BMP) is being performed. Erosion control efforts took place during this reporting <br />period following any precipitation (snow removal and runoff from melting snow and ice). <br />Page 2 of 6 MLE2 WE 29 March 2014.doc <br />
