III. COMMENTS -COMPLIANCE <br />Below are comments on the inspection. The comments include discussion of observations made <br />during the inspection. Comments also describe any enforcement actions taken during the inspection <br />and the facts or evidence supporting the enforcement action. <br />General Comments <br />This was an aerial inspection of the Munger Canyon Mine. Six oblique and near-vertical digital photo images <br />were taken by Harry Ranney of DMG on the flight of 7/14/06. The images were viewed by Dan Mathews of DMG <br />on 7/2S/06. Imagery covered the refuse disposal vicinity, portal bench area, and access road segments between <br />the refuse area and portal bench. <br />Roads <br />Details regarding the extent of maintenance to ditches, culverts, road berms, etc., as addressed in the <br />June inspection report could not be discerned from the aerial views. There were no locations of <br />evident ditch or berm breaches or other problems along the road. Culvert outlet sleeves appeared to be <br />intact. <br />Hydrologic Balance <br />There was flow in East Salt Creek, but not in Munger Creek. <br />The refuse area sediment pond was dry. <br />Detailed assessment of the condition of various drainage and sediment control structures was not possible, but <br />there were no apparent locations of ditch breaches, or sedimentation outside of the approved sediment control <br />system. <br />Backfill and Grading <br />There was no evidence of new erosion on the interim reclamation fill on the mine bench area, and no evidence <br />of renewed cracking, caving, or sloughing. Areas of the fill which had been affected by caving on top of the fill <br />and surficial sloughage on the outslope were properly graded, seeded, and mulched last fall. Seeded grass has <br />germinated and initial establishment appears to be satisfactory. <br />Processino Waste <br />Waste material in the initial disposal cell was spread and graded, with no loose dump piles. 2ntl Quarter Refuse <br />Pile certification included results of compaction testing, as requested in previous inspection. <br />Refuse cover stockpile has not yet been seeded, but was previously graded as noted in the June inspection <br />report. <br />It appears that the temporary culverted crossing of the west side refuse area collection ditch (to access the cover <br />soil pile for grading activity) was still in place. Previous inspection had requested that the temporary culverted <br />crossing be removed. The culverted crossing needs to be removed to restore the original ditch cross- <br />section. This item will be checked on the next DMG site inspection. <br />3 <br />
