November 19, 2019 <br /> 1.0 Introduction <br /> In compliance with Rule 4.09.1 (11) of the Regulations of the Colorado Mined Land Reclamation <br /> Board for Coal Mining, a quarterly inspection and report on the construction and associated <br /> activities of the Horse Gulch Fill (HGF) at Trapper Mine in Craig, Colorado has been completed. <br /> The quarterly inspection was conducted on November 19, 2019, by Tonia M. Perkins, a licensed <br /> professional engineer in the State of Colorado. Construction activity related to the fill has been <br /> consistent with the approved design. Details of this design can be found in Agapito Associates, <br /> Inc.'s (AAI) Horse Gulch Fill Stability Analysis, dated May 29, 2009. <br /> No appearances of instability, structural weakness, or other hazardous conditions were observed. <br /> Both the south west side of the fill and the north east spoil side of the fill were inspected this <br /> quarter. The area where cracks were detected on the top south portion of the dump during the <br /> first quarter of 2013 inspection was checked. There was no additional cracking found. The two <br /> spots above the 7350' elevation on the south side of the dump that showed some differential <br /> settling in the second quarter of 2013 were inspected and there was no additional settling <br /> (Photographs 1 and 2). Monitoring these areas on a regular basis will continue. <br /> The area where a spring was discovered during the third quarter 2011 inspection was inspected <br /> (Photograph 3). During the time of the inspection there was no water flow and the area was dry. <br /> Photograph 1: South Site above the 7350 Bench Elevation(1111912019) <br /> 2 <br />
