` ~ FROM MONRDN~%K • PHONE N0. 3033254600 • Oct. 25 1997 09:15PM P4 <br />RE: MEMF'lil5, FILE N0. M-97-084 Page 5 <br />SCE;~TARSO #2: This 6hows the assumed slope of the bedrock in the <br />drainage to be "45 degrees. This would place the bottom of the <br />drainage: at the cliii face above the cliff base. This would produce <br />a natural cliff. Since the drainage above this point will 1~e mined <br />down to hed rock, stability is insured. <br />SCRr7ARI0 #3: This shows the assumed slope of the bedro:~k in the <br />drainage to be "60 degrees. This would place the bottom of the <br />drainage to the east of the cliff face. This scenario could occur if <br />there is a cliff face in the drainage. In this case the area between <br />the C1ifF face and the bedrock of the drainage would be sloped 3:1. <br />Thy.; geotechnical evaluation shows that whatever the slope of <br />the drainage to the east, the proposal of mining to bedrock would <br />stabiliz: this area, irregardless of the slope angle. <br />Additional Ttems: <br />Prcuf of individual notifications of all owners of prcfaerty on <br />the permit area or within 200 feet was sent to the nenver office on <br />October :.4, 1997. The change in permit area does not affect any new <br />property owners. <br />The: copy of the published newspaper notice was also se*~t to the <br />Denver p:~fice on October 14, 1997. <br />Sincerely, <br />Robert A.
