2. Field Investigations <br /> GEI performed a field investigation within Overland Ponds Pond 2 and Treiber A in June 2014 <br /> in support of the Overland Ponds Pond 2 to Treiber A interconnect and the Treiber A slope <br /> reclamation designs. The investigation included advancing geotechnical borings near the <br /> interconnect alignment and excavating test pits within the existing slopes of Treiber A. An <br /> additional investigation consisting of geotechnical borings and topographic survey is planned <br /> for the Treiber A to Treiber B interconnect after Treiber B is dewatered in October 2014. <br /> 2.1 Boreholes <br /> Three geotechnical boreholes (B 101, B 102A, and B 103) were advanced for the Overland <br /> Ponds Pond 2 to Treiber A interconnect to investigate subsurface conditions within the gravel <br /> pit and in the unmined area between Overland Ponds Pond 1, Overland Ponds Pond 2, and <br /> Treiber A. The boreholes were field located roughly in a straight line near the proposed <br /> interconnect alignment. Boreholes were located at the toe of the embankment in Overland <br /> Ponds Pond 2 (B 101), in the unmined area between Overland Ponds Pond 2 and Treiber A <br /> (B 102A) and toe of the embankment in Treiber A (B 103). <br /> Borelogs from the investigation are included in Appendix A. Laboratory test results from the <br /> investigation are summarized below in Table 1. Complete lab testing results are included in <br /> Appendix B. <br /> l7 Field Investigations 15 <br /> G E I .., <br />
