Pile #2 will not be used until later this Spring. One sheepsfoot compactor (Cat 855) was <br />compacting the Pile #2 area. We did not observe any surface failures in either compacted <br />or uncompacted gob. The air temperature was approximately 55 degrees F in sunny <br />conditions and evidence of drainage from snow melt was observed in several of the <br />drainage culverts and ditches that serve Pile No. 2. No snow was present on the slopes at <br />the time of our visit. No additional reclamation of any portions of Pile #2 had been <br />performed since our last visit on December 17, 2013. <br />Closing <br />On -going monitoring of inclinometers and piezometers at CWDA No. 2 provides an <br />indication of the general stability of the refuse and can be useful in estimating expected <br />performance of similarly configured refuse piles at Bowie. For these reasons, we <br />recommend continued monitoring of this instrumentation on a quarterly basis. We <br />understand that as of April 1, 2014 another CMT/Geotechnical engineering firm will be <br />ascuming the duties of testing, monitoring and observation at the Bowie Mine #2 site. <br />This report then represents the final required reporting by Buckhorn Geotech, Inc. on <br />your behalf in fulfillment of the requirements of Section 4.10.2 -Site Inspection, <br />Regulations of the Colorado Mined Land Reclamation Board for Coal Mining (Revised <br />9/14/2005) on behalf of Bowie Resources, LLC. <br />We sincerely appreciate the opportunity to have worked with you on this project for the <br />past nine years. If you have any questions regarding this letter or the instrumentation <br />monitoring at CWDA No. 2, please don't hesitate to contact me at (970) 497 -8852 or <br />dan(abbuckhorngeo.com. <br />Sincerely, �d;•�`�' Y -"' •;� <br />BUCKHORN GEOTECH, INC. <br />c <br />38334 <br />Daniel C.
