May 16, 2013 C- 1981 - 010 /Trapper Mine JLE <br />A known elevation survey point is located near the water tanks in the facilities area. The Division collected an <br />elevation point at this location. The known elevation is 6,511.1 feet, the measured elevation the Division collected <br />was 6,463.6 feet. Given this, the Division's elevation measurements are generally about 47.5 feet lower than the <br />surveyed elevation. The Division added 47.5 feet of elevation to each of the elevation measures collected along <br />the transects to correct this data. Even with the correction, there is still likely some error in elevation information <br />collected with the GPS unit. However, this method allows the Division to compare the approximate grade and <br />slope of the reclaimed parcel to aid in the determination that the approved post mining topography has been <br />constructed. <br />The Division's elevation measures ranged from about 49 feet lower to 31 feet higher than the elevations surveyed <br />based on the 2012 ARR Map. On average, the Divisions elevation measures were 3.8 feet higher than the <br />elevations derived from the 2012 ARR Map. The interpolated elevations from the M12, Post Mine Topography <br />Map ranged from 17 feet lower to 34 feet higher and about 5 feet higher on average than the interpolated <br />elevations from the 2012 ARR map. There is likely some error in the interpolated elevations given the contour <br />intervals used on each of the maps. The Post Mine Topography map only has 50 foot contour intervals for some <br />of the graded areas leading to a less accurate interpolation. <br />Transect 1 was located across parcel A -B -12 in the former Ash Pit. Overall the slope and grade of the measured <br />elevation and 2012 ARR elevation cross - section is similar to the approved post mine topography cross - section. <br />The differences in the elevations at each point is minimal. It appears the Operator has graded this parcel in <br />accordance with the approved post mine topography. This parcel blends in with the surrounding reclaimed and <br />undisturbed area. <br />Transect 2 was located across part of Parcel F -A -12 where a former topsoil stockpile was located. The 2012 ARR <br />elevation cross - section indicates a consistently lower elevation than the Post Mine Topography Map and the <br />elevations measured in the field. However, these differences area minimal and the general grade and slope of this <br />portion of the parcel approximates the approved post mine topography. This parcel blends in with the surrounding <br />reclaimed area. <br />Transect 3 was located across part of Parcel F -A -12 where a former topsoil stockpile was located. The GPS <br />measured elevation points are generally lower than the approved post mine topography and the elevations derived <br />from the 2012 ARR map. However, these differences area minimal and the general grade and slope of this portion <br />of the parcel approximates the approved post mine topography. This parcel blends in with the surrounding <br />reclaimed area. <br />Transect 4 was located across part of Parcel F -A -12 where a former topsoil stockpile was located. The graded <br />topography at this parcel is almost exactly as it was depicted in the approved Post Mine Topography map and <br />2012 ARR Map. There is very little difference in the cross - sections for this parcel. This parcel blends in with the <br />surrounding reclaimed area. <br />Transect 5 was located across part of parcel F -A -12 where the former Flintlock Pit was located. The 2012 ARR <br />topography is almost exactly the same as it is depicted on the approved post mine topographic map.
