II West Coal Refuse Facility Geotechnical Investigation <br />Sedimentation Pond E Retaining Structure <br />4.0 SUBSURFACE INVESTIGATION <br />A subsurface investigation was performed in May of 2003 by MWH to examine the <br />subsurface geotechnical conditions and to develop geotechnical design parameters for use <br />in the structural analysis and design of the retaining structure. This investigation <br />consisted of excavating test pits at the site of the proposed retaining structure. A total of <br />3 test pits were excavated at the approximate alignment for the toe of the wall, with each <br />test pit excavated to bedrock. A memo detailing the test pit investigation results and the <br />geotechnical design recommendations is included in this design report as Appendix B. <br />• <br />• <br />• <br />4 <br />
