C, I C <br />N-T. V ameacN <br />A Cat D8Tdozer and a John Deere 1050J dozer worked on constructing the south perimeter road near stations <br />P8 +00 to P12 +00 and cutting the neighboring slopes to grade. A Cat CS56 smooth drum roller compacted the <br />slope and road surfaces per method spec. <br />A Cat D8 dozer and a Cat CS56 smooth drum roller were used to cut, place, and compact fill at the Phase 2 <br />Diversion Channel, <br />A Cat 330 excavator hammer hoe was breaking 1 grading the slope north of the Cripple Creek side of the Hwy 67 <br />Realignment adjacent to the road way. Excess material from this area was used as fill at the PSSA toe berm. <br />Fill material was generated for the ADR Road fill and the Buttress fill area from slope grading near Bench DD north <br />of the Crib Wall and from the and from overburden and shot rock removed near Bench A (approximate stations <br />A13 +00 to A18 +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 1 use. <br />Squaw Gulch Clay Borrow Site: Clay processing took place at the Squaw Gulch Clay Borrow Site. <br />Approximately, 6,300 tons of soil liner fill material has been produced at the Squaw Gulch Clay Borrow Site to date. <br />Underdrain System. <br />Secondary Underdrain: A Cat 330 excavator was used to complete approximately 200 LF of Secondary <br />Underdrain down slope from station 70 +00 on the ADR road. The underdrain was completed per Sheet A250, <br />Detail "Secondary Underdrain ". Approximately, a total of 4,054 feet of Secondary underdrain has been completed. <br />Primary Underdrain: No work was performed on the Primary underdrain during this reporting period. A total of <br />1,294.60 feet of Primary underdrain has been completed. <br />Tree /Slash Grubbing and Clearing, Chipping: <br />A Cat 330 was observed clearing and grubbing near station A0 +00 above the former Hwy 67 roadway and the <br />PSSA Toe Berm. <br />B) Underground Workings <br />Confirmatory drilling was performed on underground working No.6102, 6336, 6337, 6338, 06366, U6369, U6370, <br />and U6388. All borehole locations were established on a 4 -foot center isolating any voids found. Further <br />remediation efforts will be ongoing until remediated. Summary of the remediation efforts will follow when <br />remediation is completed. <br />UG #U6394: Unknown, previously found to be a 2X5 "timbered drainage culvert': <br />Approximately, 70 -feet of the culvert was removed. Work to continue. <br />Underground working No.6304 was blasted and then remediated using a 2- layered geogrid system. <br />UG 46260: Known Adit, within Phase 2 diversion Ditch and North Access road: <br />Attempted to locate the previously located adit. Possibly under recently placed fill. Location to continue next week. <br />Underground working No. 6365 was excavated to competent bedrock, then backfilled and compacted. The working <br />is considered remediated. <br />Page 2 of 6 NILE2 WE 12.7.13.doe <br />
