CIVDA No. 2 ^. <br />41113.}9.000j 1luddle. ton -NeIIN <br />IUl2U'ld ��_ <br />The recorded increases it) pore pressures at VWP -08 are consistent with the fact that gob <br />placement has occurred in the vicinity of this instrument during the spring and suminer of 2014. <br />It is likely that additional increases in pore pressures will be recorded as coal refuse is actively <br />placed in the vicinity of VWP -08. However, the increases in pore pressures are not anticipated <br />to be sufficient to reflect instability in CWDA No. 2. <br />VPVP -09 <br />VWP -09 was installed on May 18, 2012 near the toe of CWDA No. 2. The pore pressures <br />recorded at VWP -09 have been fairly steady since installation. This suggests that dewatering of <br />the gob in this area is likely nearly complete, It is anticipated that the pore pressures at VWP -09 <br />will remain fairly steady over tinge. <br />I/PVP-10 <br />VWP -10 was installed on May 18, 2014 near the toe of CWDA No. 2. The pore pressures <br />recorded at VWP -10 have been fairly steady since installation. This suggests that dewatering of <br />the gob in this area is likely nearly complete. It is anticipated that the pore pressures at VWP -10 <br />will remain fairly steady over time. <br />Site Visit Observations <br />HBET visited the site on September 30, 2014. At the time of our visit, coal waste was not being <br />placed at CWDA No. 2, In general, CWDA No, 2 appeared to be in good condition and no <br />evidence of instability or other adverse conditions were observed, <br />At CWDA No, 3, coal waste was being moved to and from the drying area to facilitate drying. <br />Recent rains prevented the material from being placed and compacted. At the east end of <br />CWDA No. 3, coverfill was being excavated in the area of a proposed new drying area. <br />General <br />In general, based upon the results of the recent VWP and inclinometer monitoring data, HBET <br />does not believe that there is any reduction in the stability of CWDA No. 2. Continued quarterly <br />monitoring of piezometers and inclinometers is recommended. <br />We are pleased to be of service to your project.
