Some water was observed in the test holes and appears to be moving <br /> through the site. None of the stakes showed any indication of ground movement although some <br /> sloughing of dry material was observed towards the top of the slide. <br /> On Thursday July 19`h a representative at Division of Reclamation Mining and Safety, Eric Scott, <br /> made a site visit. He was accompanied by APC representative, Curt Wilson. Mr. Scott took photos, <br /> did some measuring and walked the site. APC Construction received the area calculations from the <br /> slide and disturbed area from Pinyon-Environmental and submitted them on the morning of July 19th <br /> to Division of Reclamation Mining and Safety. <br /> Jim Kowalsky PE of Ground Engineering recommended that we move some additional lose material <br /> inside the upper area of the original slide. This material was left in place waiting on a <br /> recommendation from the engineer. Starting today July 23`d, we started to move that material; we <br /> expect to complete that operation in several shifts this week. <br /> Please feel free to call if you have any questions, 303-434-1668. <br /> Thanks, <br /> Af .#P� <br /> Stanley C.
