Geotechnical Data Technical Memorandum <br />Hazeltine -Road Runners Rest II Gravel Pit Lining Project <br />December 2000 <br />Methods of sample collection for each potential material source are described in the following ' <br />sections. <br />3.4.1 Hazeltine Pit <br />The south and west stockpiles in the Hazeltine Pit were sampled during the Phase One ' <br />test pit excavation. Information on sample collection methods is provided in Section 3.3. <br />Bulk samples were taken from the beach that formed around and downstream of the ' <br />discharge line at the tailing pond. A shovel was used to excavate 6 to 10 holes, 1 to 2 feet <br />deep in the exposed surface of the tailings. Representative samples from each hole were ' <br />placed in a lazge cloth bag. The bulk sample was identified as HZTP-1. The samples <br />were taken at the northeast part of the tailings pond at the approximate location shown <br />on Figure 3.1. , <br />3.4.2 Howe-Haller Pit <br />Bulk samples were collected from the west face of the Howe-Haller overburden ' <br />stockpile, which is located about 1500 feet south and 800 feet east of the southwest ' <br />corner of the Hazeltine pit. The west face of the stockpile contained three benches. Each <br />bench was about 150 feet long, 15 feet wide and about 8 feet lower in elevation than the <br />previous bench. The Field Engineer identified the benches as top, middle, and bottom. , <br />Bulk samples were obtained from five to seven locations on the near vertical face above <br />each bench using a hand shovel. The samples from each bench were placed in a lazge <br />cloth bag. The bulk samples were identified as HSP-1, HSP-2, and HSP-3 which <br />correspond to the bottom, middle, and top bench, respectively. <br />Bulk samples were taken from the beach that formed around and downstream of the ' <br />discharge line at the tailing pond. A shovel was used to excavate 6 to 10 holes, l to 2 feet <br />deep in the exposed surface of the tailings. Representative samples from each hole were <br />placed in a large cloth bag. The bulk sample was identified as HWTP-1. The samples , <br />were taken at the northwest part of the tailings pond as show on Figure 3.
