Such remedial measures would <br /> have to be implemented if the intensity of rockfall were such <br /> that the sound sandstone at the crest of the cut were slough- <br /> ing and the road immediately above it were endangered. <br /> Other rock cuts at the site are of lesser importance <br /> even if they are occasionally very steep and very high. Prob- <br /> lems of rockfall from these cut faces are the only problem. <br /> They have been reduced or eliminated by using the part im- <br /> mediately below the cut as a protective berm. Such an arrange- <br /> ment is being used below the cut at the parking space east <br /> of the office and warehouse level, at the cut above the office <br /> and the warehouse, at the cut above the crushing and screen- <br /> ing level, and below the cut that is located above the road <br /> between the office and warehouse level and the crushing and <br />• screening level. These last two cuts have been excavated in a <br /> very competent sandstone of the Rollins Member. <br /> We do not feel that any remedial measures are required <br /> at these rock cuts for stability purposes. Remedial measures <br /> would be necessary only if the rockfall problems comprised a <br /> safety hazard. <br /> 4.4 SOIL CUTS <br /> As shown on the Geotechnical Map, there are numerous <br /> cuts in soils at the site. They have been excavated between <br /> the individual levels, such as the large soil cut between the <br /> fan level and the portal level, and along the road that <br /> connects individual levels. The soil cuts at the site have <br /> been excavated at various slopes between 45 and some 55 de- <br /> aaNVO4ocowixn~c.MC. <br />
