..,; , 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 completed promptly. Due to time limitations, the entire road length was not walked during the inspection, but this will be done during an inspection later this summer. Hvdrolooic Balance There was flow in East Salt Creek, but not in Munger Creek At the portal area, SAE-1 sediment control rock check structure was intact and functional. The sump area was dry. Silt fences directly east of the rock check require some maintenance. In a couple locations the fabric has pulled away from the stakes and needs to be re-stapled, and in a couple locations the fencing is not properly trenched in, and needs to be re-trenched and secured. At the west end of the portal area, the diversion ditch that directs upland flow away from the bench area and conveys flow to the 48" upper road culvert requires maintenance. Specifically, there has been down- cutting along the upper steep segment of the ditch, and deposition of gravelly sediment along the flat segment of the ditch (near an old 12' diameter half-culvert portal structure). Large rock needs to be placed along the steep eroded segment of the ditch, and sediment needs to be removed from the area of deposition. At the waste disposal site, it appears that the surface casing of monitoring well GW-6 was damaged and covered over by recent grading activity at the non-toxic refuse cover soil stockpile. The well will need to be repaired or replaced as necessary, prior to the end of June, 2006. Backfill and Gradin There was no evidence of new erosion on the interim reclamation fill on the mine bench area, and no evidence of renewed cracking, caving, or sloughing. Areas of the fill which hatl been affected by caving on top of the fill and surficial sloughage on the outslope were properly graded, seeded, and mulched last fall, and seeded grass has recently germinated. Processing Waste Additional coal waste material from the sediment drying area at McClave Canyon Mine had been placed in the initial disposa! cell since the previous inspection. The material had been graded in an approximately level layer across the disposal cell. Prior to disposal of additional material, the disposal should be inspected and certified by a professional engineer, and necessary compaction testing should be conducted. Soil sediment material removed from the disposal area sediment pond last fall was placed in several locations on the top of the non-toxic cover soil pile for drying. The material has largely dried out and rough grading was recently undertaken, to spread the material over the surface of the stockpile. There appeared to be some muddy areas remaining near the center of the site. Some further ripping/grading may be necessary upon further drying to break up clods and relieve compaction. The upper diversion along the upper edge of the cover material stockpile was in place, but additional grading is necessary to restore the approved design. A steep ridge of loose graded soil along the length of the ditch needs to be smoothed out, a small hole and adjacent accumulation of dirt near the west end of the ditch need to be eliminated, and the riprapped lower segment into the sediment pond needs to be restored. Following completion of all grading work, the disturbed area will need to disked or otherwise scarified to prepare a proper seedbed, followed by seeding with the stabilization seedmix, and mulch application. Seeding should be delayed until late summer (midJuly to mid-August) or fall dormant season (mid to late October). 4
