Longwall Panel E1 was mined - <br />out by the Third Quarter of 2010 and Longwall Panel E2 by the Third Quarter of 2011. By the <br />end of the Fourth Quarter of 2011, MCC had longwall mined up to an area between cross -cuts <br />57 and 56. During the Fourth Quarter of 2011 the area potentially affected by subsidence from <br />mining was mostly inaccessible for the weekly and monthly inspections due to snow cover and <br />consequently, the ground surface was not visible. Longwall mining did not occur within one <br />mile of Monument Dam. Mining was within the angle of draw of Forest Service Road FS711 <br />and Stock Pond P36, and they were undermined. These land features and man -made <br />structures were inspected in the third quarter when road and weather conditions permitted, <br />and these inspections will be included in the Fall 2011 Semi - annual Subsidence Report. <br />These features will be inspected for post mining effects when road and weather conditions <br />allow. It should be noted however, for the period of time before snow, there were no visible <br />signs of subsidence induced features. Quarterly routine inspection reports for Monument <br />Dam, Forest Service Roads, and Stock Ponds are included with this letter. <br />Should you have any questions or need further information concerning this Fourth Quarter <br />2011 Report, please feel free to contact me at (970) 929 -2308. <br />Sincerely, <br />Robin J.
