indicated that they will again graze the reclaimed area this summer (2001) at about the <br />same rate. <br />Hydrologic Reclamation (Sedimentation) -The Operator used sedimentation modeling <br />to further demonstrate Phase II Bond Release criteria (Rule 3.03.1(3)(b)) have been met <br />using the Revised Universal Soil Loss Equation (RULSE). These calculations were <br />confirmed by the Division. The calculated (estimated) sediment yield for the reclaimed <br />Pit 1 was 0.83 Tons/Acre/Year. The calculated (estimated) premining sediment yield was <br />2.30 Tons/Acre/Year. This gives an estimated postmining sedimentation yield of 35% of <br />the premining yield. The criterion for sedimentation for this area has been met. <br />The inspection confirmed the calculations. With the exception of the exclusions noted <br />above, there was no noticeable erosion on [he reclaimed Pit 1 and both of the ditches <br />(PD3 and PD4) did not appear to contain any sediment. There also did not appear to be <br />any sediment being deposited at the inlet of the culvert running under the road. The areas <br />that have been excluded from this bond release did not appear to be contributing sediment <br />to the other azeas of Pit 1. <br />Summary and Conclusion -Based upon a review of the mine permit and approved <br />reclamation plan, the bond release application and the site inspection, the Division finds <br />that KCC has successfully demonstrated that Pit 1 has adequate topsoil replacement, <br />vegetative cover and hydrologic reclamation (sedimentation). <br />IV. PROPOSED DECISION <br />Based on the observations above, the Division proposed to approve KCC's request for a <br />Phase I Bond Release at the Loadout and Phase II Bond Release for the 720 Pit and Pit 1. <br />This proposed decision will release the applicant from liability for backfilling, grading <br />and drainage control on 6.9 acres at the Loadout and topsoil replacement and hydrologic <br />reclamation (sedimentation) on 169.0 acres for the 720 Pit and Pit 1. Excepted from the <br />loadout is the sediment pond. Excepted from the Pit 1 area is the 3.6 acres mentioned <br />above, in OBSERVATIONS AND FINDINGS. <br />The Division holds a performance bond of $1,817,911.00 for the Marr Mine. The <br />Division is proposing to release a total of $1,117,641.00, as detailed below. <br />The pottion of the bond pertaining to the Loadout is $14,120.00. The Division proposes <br />to release 60% of the loadout azea bond, or $8,472.00. The remaining bond of $5,648.00 <br />is sufficient to assure completion of the remaining reclamation work at the site if the <br />work had to be performed by the Division. This work includes reestablishment of <br />vegetation. <br />The portion of the bond pertaining to the 720 Pit was $3,618,694.00 (prior to Phase I <br />Bond Release for this area). The Division proposes to release 25% of the 720 Pit bond, <br />Marr Mina SL-0? 8 <br />
