-5- <br />Evidence of previous activity in the area consists of <br />remnants oC a coal transport mechanism on the hillside to the <br />south, coal refuse on the site and irrigation ditches (dry) which <br />cross tYie site. The extren.e lower part of the site is fallow <br />agricultural land and the lower central part oC the site is graz- <br />ing land. Vegetation on the upper (natural) part of the site <br />consists of moderately thick to thick sagebrush with some weeds <br />and grass. Some large boulders t~~ about 6 feet size are scat- <br />tered across the site, <br />At the time of our field work, an access road had been cut to <br />tl~e proposed western mine portal (No, 2). The road was mainly <br />cut. The cuts were very steep and exposed the alluvial fan <br />deposits consisting of clays, sands and gravels with cobbles and <br />• boulders. The eastern enci of the road cut exposed white limey <br />sandstone, t}o indications of massive slope movement or seepage <br />were observed in the cut faces. <br />After our field work at the site and before issuance of this <br />report, grading of the site to achieve the planned grades as <br />shown on Fig. 1 had begun. <br />GcOLOGIC CONDITIONS <br />The geologic conditions of t}~e area were described in our <br />previous report. Conditions that could adversely impact the site <br />consist of hydrocompactive and swelling soils, constructicn <br />induced slope instability, debris flow, erosion, seismicity and <br />rockfall. <br />• <br />Chen & Associates <br />
