TOPSOIL REMOVAL, STORAGE AND REDISTRIEL'TION PLAN <br />The topsoil removal, storage and redistribution plan has been modified a <br />number of times due to changes in production rates, changes in scheduling of <br />areas to be mined, additional leases, etc. However, the most up to date <br />life of mine topsoil plan which supersedes all past revisions is the Revised <br />Life of Mine Topsoil technical revision submitted August 9, 1985 and <br />approved March 17, 1986. The schedule, yardages, and locations for all <br />topsoil movement and storage are shown on Permit Renewal Tables 5, Topsoil <br />Balance by Areas, Life of Mine; 6, Yearly Topsoil Laydown Area Summary; <br />and 7, Topsoil Movement and Permit Renewal Maps 7 and 8, Life of M1tine <br />Topsoil Plan. Yardages and depths are correct; however, as pointed out in <br />the technical revision, some scheduling changes may be necessary. Delays in <br />obtaining approval for regraded contours have already caused delays in <br />topsoil redistribution. <br />In order to move the topsoil in stockpiles 26/27-51, a temporary crossing <br />will be constructed in the southern tributary of Foidel Creek. Prior to <br />constructing the crossing, an access road will be constructed to link <br />• topsoil stockpiles 26/27-51 to the regraded spoil in Area 51. The access <br />road is shown on Permit Renewal Map No. 7. <br />The access road will require salvaging topsoil, which will be accomplished <br />by either stockpiling it at a central location or windrowing it to the <br />side of the road. The read will traverse 3 different soil series and <br />redistributed topsoil. The series and respective topsoil salvage depths are <br />as follows: Aaberg Silty Clay (Mapping Unit 35C) - 13 inches; Aaberg <br />Silty Clay (Mapping Unit 35D) - 28 inches; and Gapo Clay Loam (Mapping <br />Unit 23A) - 24 inches. In addition, approximately 18 inches of topsoil will <br />be bladed from a segment of the access road that will be constructed within <br />the reclaimed area. <br />The road will be constructed so that the overall yrade does not exceed 10%. <br />Likewise, the grade will not exceed 15% for any consecutive 1,000 feet, nor <br />will there be more than 300 feet within a 1000 foot section where the grade <br />exceeds 15%. The slopes of the road cuts will not exceed 1V:1.SH. All of <br />• the drainage from this road will enter into Pond A. Therefore, no other <br />sediment control measures are required. <br />Tk 89-25 Permit Renewal 780-107-1 Revised 06/26/89 <br />
