June 19, 2012 C-1981-012/New Elk Mine JHB the east end of the pile, north of Culvert C13 was being dug out to allow for settling of sediment prior to flow entering culvert C13. The inspector took 10 slope readings using a hand held inclinometer (Suunto PM-5/360 PC ) and a hand held rangefinder (Bushnell yardage pro).The approved construction technique and dimension of DWDA#2 are in permit section 2.05 (p. 2.05-44) and figure 13. Measurements were taken from the top of the pile. Measurements were collected from the east end of DWDA#2 alternating from the north to the south sides of the pile and moving towards the west end of the pile. site 1: eastern slope.- 8.5 degrees (15%). This slope is approved not to exceed 20%. the East slope of the pile is in compliance with the plan. site 2: East end of pile north slope:- 26 degrees (49%) Figure 13 shows this slope not to exceed 50%. This portion of the slope is in compliance with the plan. site 3:east end of pile, south slope: -26 degrees (49%). Figure 13 shows this slope not to exceed 50%. This portion of the slope is in compliance with the plan. Walked approximately 300 feet west to site 4 and 5. Site 4: south of highway 12 culvert, north slope,- 24 degrees (44.5%). Figure 13 shows this slope not to exceed 50%. This portion of the slope is in compliance with the plan. Site 5: south slope of pile, -24 degrees (44.5%). Figure 13 shows this slope not to exceed 50%. This portion of the slope is in compliance with the plan. Walked approximately 325 feet west to site 6 and 7. Site 6: North slope, -23 degrees (42.5%). Figure 13 shows this slope not to exceed 50%. This portion of the slope is in compliance with the plan. Site 7: South side of pile, -25 degrees (46.5%), Figure 13 shows this slope not to exceed 50%. This portion of the slope is in compliance with the plan. Walked approximately 325 feet west to west end of pile. site 9 includes the ramp for truck access on to the pile. Site 8: north slope of pile including truck ramp, -18.5 degrees to ramp, -29 degrees ramp to road. Site 9: south slope at west end -23 degrees (43%) Site 10. West slope of the west end of the pile, -23 degrees. (43%). Width of pile at Site 8 to 9 =11yds (=33 ft.) This meets the requirement for a top width of 20 feet.
