Mr. Jim Stover <br />August 9, 1996 -New App./Bowie 2 <br />Page 15 <br />date." BRL hired Morrison Knudsen (M-K) to address the geotechnical stability of the <br />proposed surface facility area of the Bowie No. 2 Mine. M-K, in turn, subcontracted with <br />Maxim Technologies, Inc., to complete a geotechnical investigation of the site. <br />The demonstration of long term geotechnical stability of the proposed reclaimed <br />configuration of the surface facilities will have to be thoroughly analyzed. Specific stability <br />analyses will have to be prepared for representative proposed reclaimed cut and fill <br />situations, including haul roads, conveyor corridors, and various facility benches, etc. <br />Appropriate material properties will have to be selected and justified for the anticipated <br />recLtimed site characteristics. This concern must be adequately addressed before any <br />decision can be proposed by the Division. <br />72) This response is generally acceptable. Please explain why permanent culverts are preferred <br />as opposed to some type of low water crossing. <br />2.05.4(2)(d) -Topsoil Redistribution <br />72a) The May 31, 1996 DMG letter references a stipulation and the probable stipulation contents. <br />Dces BRL agree with the statements contained in the May 31, 1996 DMG letter, and the <br />proposed range of redistributed topsoil depths? <br />2.05.4(2)(e) - Reve~etation Plan <br />73) Response accepted.
