Th operator has applied for a partial bond <br /> release on much of the reclaimed area, SL3. This inspection was a follow up inspection to observe the condition <br /> of the reclamation as it pertains to the bond release request. Portions of the area associated with SL3 were snow <br /> covered and inaccessible during the Division's previous inspection. The ground was clear of snow and dry,with <br /> clear weather. <br /> The inspection was accompanied by Mindy Sickels of Elk Ridge Mining and Reclamation. The site was not active <br /> during the inspection. Four Photos accompany this report to illustrate the current site conditions <br /> HYDROLOGIC BALANCE -Rule 4.05 <br /> Drainage Control 4.05.1,4.05.2,4.05.3; Siltation Structures 4.05.5,4.05.6; Discharge Structures 4.05.7,4.05.10; <br /> Diversions 4.05.4;Effluent Limits 4.05.2; Ground Water Monitoring 4.05.13; Surface Water Monitoring 4.05.13; <br /> Drainage —Acid and Toxic Materials 4.05.8;Impoundments 4.05.6,4.05.9; Stream Buffer Zones 4.05.18: <br /> The focus of this inspection was to observe two areas associated with SL3 that were inaccessible during <br /> the Divisions previous inspections. The two areas are the buried portion of the CC irrigation ditch and the second <br /> is the reclaimed sediment control structure and ditch located just south of Meehan Draw. <br /> The reclaimed footprint of the buried CC irrigation ditch includes approximately 2.7 acres. The area was observed <br /> to be in good condition,the reclaimed area shows no signs of settling, slumping or erosional features. The buried <br /> ditch runs adjacent to the abandoned surface ditch,and is vegetated. The vegetative cover was dormant at the time <br /> of the inspection,but was dense,diverse and multiple years biomass was observed indicating the vegetation is <br /> capable of self-regeneration. No state listed noxious weeds were observed in this area. Photos One and Two show <br /> examples of the reclaimed area adjacent to the abandoned surface ditch. <br /> The second area observed was the reclaimed sediment control structure and ditch located just south of Meehan <br /> Draw. This area encompasses approximately 3.7 Acres and was observed to be in good condition. The footprint <br /> of the area is indistinguishable from the adjacent undisturbed areas. No signs of settling, slumping or erosion was <br /> observed and the area is well vegetated. The vegetative cover is dense,diverse and well established.
