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 /> Inclinometers <br /> In 2005, three inclinometers, designated BG05-04, BG05-05, 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 3rd Quarter 2019 monitoring was <br /> completed by DOWL on September 30th, 2019. The monitoring report prepared by DOWL <br /> includes a site plan showing the locations of the inclinometers and cumulative displacement <br /> curves relative to the baseline readings in 2005. Axis "A" reflects deformation with depth in the <br /> direction of anticipated movement perpendicular to the face of the gob. Axis "B" reflects <br /> deformation with depth parallel to the face of the gob. <br />
