I could not lcr~te a:. <br />other areas of Ponding, t-.cwever, the snc.: cover hampered my searcz. The <br />underdrains lccated in the bench eutslcVe were flrained at the time of cur <br />instection. " <br />'^:e borrow area located directly south of the hig.:all and used to supply mater <br />for bac'.;filling the }:ic::arall eras reclaimed to a slope wricY: did not exceed the <br />dasigreci sloce. <br />Rased upon my in-"ecticn of the site a.d observations ride by the bII.RD, I feel <br />that the nine bench nutslope, the backfilled hichwall, and the borrow area are <br />adeouately reclaimed in accordance with the acproved reclamation plan for Phase <br />1 bond release. T2:e Permanent diversion, howe~~er, is rot adequately reclaimed <br />and is r::;t furcticnirg as desicred as evidenced by the large arount of pcndinq <br />water. The 1•IL,P.D and tre C~r~any engire_r have di=_cussed remedial mr 3sures to <br />be taken by the Cc:rpany w'~en weatrer per,+its. h~RD suc;ested that the Ccsr~any <br />regrade tl_e bend: to achieve a 5% grade into the permzr:ent diversion and regradE <br />t`.e diversion to achieve a 2a grade along the diversion. I corcvr with t`:e <br />I _.TD' s sucgesticn. Tl:e ter5ch outslope has not s'ra.•n ary movement other tinan <br />e~cpectEd cue to settlement. The outsloe is surveyed grarterly and the <br />Piezecmeter netc:or'~ is monitored rrnnti•1}~. The cutslocz shows no signs o_° beirc <br />unstable at this tirre. Fowever, a prcP.erly functionir.? Permanent diversion is <br />necessary to insure the future stabili ;• of the outslePe. Therefore, I do not <br />recommend Phase 1 bond release until Blue Rirbon Coal Ccmaany corrects t'-e <br />crainace prcble_-~ of the Permanent diversion. <br />Su.~itted by• a J ~\c,un.1.Q.C. 1 / P g _ <br />Late <br />1^( r <br />I.~a.r ~PS'I 4yr(SO u.. 2 O O <br />Section Chief Date <br />
