I, Jared Ebert of the Colorado Division of Reclamation,Mining and Safety(Division) <br /> conducted the inspection. Christine Belka and Alan Boehms with the Office of Surface Mining (OSM),Jennifer <br /> Maiolo with the Bureau of Land Management(BLM) along with Roy Karo and Jay James with SCC accompanied <br /> me during the inspection. <br /> BACKFILL and GRADING—Rule 4.14; Contemporaneous Reclamation 4.14.1,Approximate Original Contour <br /> 4.14.2;Highwall Elimination 4.14.1(2)(f); Steep Slopes 4.14.2, 4.27;Handling of Acid and Toxic Materials <br /> 4.14.3; Stabilization of Rills and Gullies 4.14.6: <br /> There are several areas that have been disturbed as a result of the mining operation that were only minimally <br /> disturbed and were not necessarily mined that are currently under consideration for Phase I bond release. These <br /> areas include the bond release parcels around Pond 016, The area surrounding Pond 006, and the maintenance <br /> shop area. A 9.4 acre parcel was mined in the Wadge Mine Area and partially auger mined. This area <br /> encompasses the pit-ramp slide area. Each of these parcels was observed during this inspection. <br /> In order to determine if these areas were configured in accordance with the approved post mine topography,the <br /> Division walked 5 transects in each of these area. Three transects were walked during this inspection and two <br /> transects were walked during the Division's inspection on May 14, 2013. Along each transect,elevation points <br /> were collected every 100 feet using a Trimble YUMA GPS unit. At each point the coordinate location and <br /> elevation were recorded. Using ArcMap®these data points were downloaded from the GPS unit and projected on <br /> the approved post mine topography map; Exhibit 20-2,that the Division geo-referenced using this program. At <br /> each elevation collection point the Division was able to interpolate the elevation of the approved topography based <br /> on Exhibit 20-2. Given the level of accuracy of the GPS unit used to collect elevation points in the field,the <br /> Division found a known survey point;No. 3008, on site. The elevation of this point is surveyed to be 8076.82 <br /> feet. The Division collected an elevation point at this location and found it to be 8051.823 feet, about 24.997 feet <br /> lower than the known survey point. For each elevation point measured in the field,the Division used a 24.997 foot <br /> factor to correct the measured elevation. Using Microsoft Excel®,the Division was able to chart and compare the <br /> Number of Partial Inspection this Fiscal Year: 12 <br /> Number of Complete Inspections this Fiscal Year: 4 <br /> Page 2 of 12 <br />
