CWDA No. 3 <br />#01349 -0001 ;' Hudd[eston -Berry <br />04/20/15 ��'% enmrmss r= me, uc <br />Site Visit Observations <br />HBET visited the site on March 11, 2015. At the time of our visit, gob on top of CWDA No. 3 <br />was being moved around and compacted. In addition, wet gob was being placed in the drying <br />area at the southeastern corner of CWDA No. 3. <br />At the time of our site visit, a very small quantity of water was emanating from the underdrain <br />below the center of CWDA No. 3. In addition, several wet areas were observed along the south <br />side of CWDA No. 3. It was unclear if these areas reflected seepage from gob dewatering or if <br />they were simply wet from snowmelt. These areas will be re- evaluated during the 2nd Quarter <br />2015 site inspection. In general, no evidence of instability of other adverse conditions were <br />observed at CWDA No. 3. <br />General <br />In general, based upon the results of the recent VWP monitoring data and our observations at the <br />site, HBET does not believe that there is any reduction in the stability of CWDA No. 3. <br />Continued quarterly monitoring of piezometers is recommended. <br />We are pleased to be of service to your project.
