The intent of the monitoring was to <br />detect significant changes in the pore water pressures or significant displaccments within the coal <br />waste which may impact the stability of the waste pile. <br />Inclinometel•s <br />In 2005, three inclinometers, designated BGO5 -04, BGO5 -05, and BG05 -07, were installed at <br />CWDA No. 2 through the coal refuse and into the native foundation soils. The inclinometers <br />have been monitored quarterly since August 2005. The 2`1 Quarter 2014 monitoring was <br />completed by Buckhorn Geotech, Inc. (BGI) on June 29, 2014. The monitoring report prepared <br />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 />
