Squire ~~ ~~ <br />I have reviewed the maps and other information submitted by Holnam, Inc. on <br />August 11, 1992. I have the following comments/questions. <br />f coo <br />~~ qb <br />~` <br />~.~\ o <br />r <br />~ /e]6 ~ <br />Roy Rompr <br />Governor <br />Michael B. Long <br />Division Dlredor <br />1) In the beginning of my memo of June 16, 1992 to you I stated that Holnam should <br />commit to grading all slopes (other than stable highwalls) to a grade no steeper <br />than 2H to 1 V. Has Holnam made this commitment? <br />2) As stated under comment #4 of my June 16 memo, Holnam should commit to <br />marking on their maps any highwall areas which will remain after reclamation which <br />are steeper than 2H-1 V. Also they should commit to building ramps of less than <br />2H-1 V at 1 /4 mile intervals across any highwall areas steeper than 2H-1 \/ to <br />provide access across the highwalls for livestock and wildlife. <br />3) Holnam must respond to comment No. 5 of my June memo (also item 5 ~~f the <br />June 24, 1992 letter to Holnam from Berhan Keffelewl. This comment i:: quoted in <br />full as follows: <br />"The approved mine plan page 3, Exhibit E -Reclamation Plan states that <br />"Where ample overburden is available highwalls will be eliminated." Holnam <br />should provide the Division with a map showing where the highwalls will be <br />eliminated and where they will not. Where they will not a plan must be <br />provided describing what slopes they will be reclaimed to, the methods to be <br />used, and the volumes of material required. Across section of these area is <br />also necessary in order to calculate the bond." <br />With this information a final bond calculation can be made. <br />GRS/yjb <br />,.. iii iiiiiiiiiiiiiiii <br />STATE OF COLORADO <br />m:\oss\yjb\holnam <br />
