III. COMMENTS - COMPLIANCE Below are comments on the inspection. The comments include discussion of observations made during the inspection. Comments also describe any enforcement actions taken during the inspection and the facts or evidence supporting the enforcement action. immediately to the south of the east end of the construction dirt stockpile. Ditch maintenance is necessary to clear out the obstruction and restore the original ditch cross section in this location. SAE silt fence structures appeared to be properly maintained and functional. Topsoil The cheatgrass infestation on the topsoil stockpile was sprayed with Round-up herbicide last fall. Treatment appeared to have been effective, there has been no cheatgrass germination subsequent to herbicide application. Seeding with the stabilization seedmix will need to be undertaken this fall. Support Facilities The operator has encountered poor roof conditions and high ash coal in recent weeks, and there are large quantities of high ash coaly material stockpiled in the coal yard area and in the sediment drying area near the sediment pond. Storage capacity in both of these locations appears to be full. The operator recently submitted a minor revision application to expand the size of the sediment storage stockpile area. The Division issued an approval decision on December 3, but implementation of the storage area expansion approval is contingent upon submittal of additional bond in the amount of$6,740.00. The approved permit requires submittal of a technical revision plan for a permanent coal mine waste disposal area in the McClane Canyon permit area prior to the end of 2007. It was noted that coaly material had been pushed to the edge of the containment berm along the east side of the sediment storage pile location. The material needs to be pulled back or the berm built up as necessary to prevent sloughage outside the berm. The area of the construction dirt stockpile that was recently disturbed and graded will need to be seeded (following any additional disturbance associated with berm maintenance in the sediment drying area). I hiked up the reclaimed light use road along the North Fork of Munger Creek to the reclaimed drill pad location. The Drill pad was regraded and seeded in January 2006. An excellent stand of seeded vegetation has become established across the site. Species observed include slender, thickspike, and bluebunch wheatgrass, bluegrass, basin wildrye, green needlegrass, Indian ricegrass, rubber rabbitbrush, big sagebrush, four-wing saltbush, winterfat, Rocky Mountain penstemon, Palmer penstemon, and blue flax. Due to the extent of vegetation cover, soil roughness, woody debris and litter, there is essentially no erosion. The extent of bare ground appears to be lower than on adjacent undisturbed slopes. Silt fencing at the drill site was intact and functional, but based on the extent of cover and observed lack of erosion, continued maintenance of the silt fencing does not appear to be warranted. Seeded vegetation is also becoming established along the reclaimed light use road downstream of the drill pad area, and no problems were noted. 4
