The intent of the monitoring was to <br />detect significant changes in the pore water pressures or significant displacements within the coal <br />waste which may impact the stability of the waste pile. <br />Inclillonleter5 <br />Ill 2005, three inclinometer's, designated BG05 -04, BG05 -05, and BG05 -07, were installed at <br />CWDA No. 2 through the coal refirse and into the native foundation soils. The inclinometers <br />have been monitored quarterly since August 2005. The 3rd Quarter 2014 monitoring was <br />completed by Buckhorn Geotech, Inc. (BGi) on September 24, 2014. The monitoring report <br />prepared by BGI includes a site plan showing the locations of the inclinometers and cumulative <br />displacement curves relative to the baseline readings in 2005. Axis "A" reflects deformation <br />with depth in the direction of anticipated movement perpendicular to the face of the gob. Axis <br />"B" reflects deformation with depth parallel to the face of the gob. <br />
