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. General Comments This was a complete quarterly inspection of the surface facility areas and office records at the McClane Canyon Mine. The inspection was conducted by Dan Mathews of the DMG Grand Junction Field Office, accompanied by Walter Whitledge of CAM. Weather was clear and mild. The site was snow-free; ground conditions were moist/muddy in the portal area, relatively dry elsewhere. Mining activity had been temporarily suspended for underground maintenance. A contractor arrived on site near the conclusion of the inspection, and has been scheduled to initiate "dirtwork" maintenance at McClane and Munger Canyon Mines over the next couple weeks, including various items detailed under "Roads" and "Hydrologic Balance", below. Availability of Records Records were on file and up-to-date, through the 4th Quarter, 2005. The updated SPCC plan (dated 11105) was properly on file. The missing SPCC/Materials Containment plan had been noted as a concern in the 4`h Qtr 2005 inspection report. Syns and Markers The Mine I.D. sign needs to be revised to reflect the recent permittee name change to CAM Mining LLC. Roads As noted in the previous inspection, Culvert "P" was recently installed on McClane Creek at the lower haul road crossing, between the office and the sediment pond. The riprap plated fill embankment constructed immediately west of the culvert inlet across the old diversion channel does not appear to conform with the elevation depicted on Map Figure 2.2-3. The fill embankment needs to be built up to increase the elevation by approximately two feet. The final elevation should be higher than the top of the culvert inlet (to ensure that the embankment would not be overtopped when the culvert is flowing full) but lower than the adjacent road surtace (to prevent flooding of the office area if the culvert is over-topped). The reconstructed embankment will need to be protected with large riprap. Additional large riprap "energy dissipaters" need to be securely set in place below the ouffall of Culvert "P", to ensure that channel scour will not result when the culvert is flowing at design capacity. Additional grading work is warranted in the vicinity of the inlet to Culvert "H" (the culvert beneath the upper road crossing of McClane Creek). Sediment excavation late last fall left steep banks of sediment along the channel upstream of the culvert inlet, along the base of the road fill. The sediment needs to be "pulled back" to eliminate the steep bank. Following grading to create a more uniform slope, the slope should be roughened and seeded. a7'
