March 21, 2012 C-1981-035/King Coal Mine MLT by wayward trucks; clean sediment from ditches and culverts; ensure that grates and drop inlets are open and drain freely; and reestablish the hillside ditch on the mine portal access road, as shown on Tab 25 Detail 9. At the upper end of the West Clearwater Ditch, a boulder placed as a safety barrier had fallen down into the ditch (Photo 3). Mr. Wymore made notes throughout the inspection, and indicated that maintenance activities would be conducted soon. • The major maintenance challenge appears to be damage to the various features being caused by vehicles that have deviated from established roadways (Photo 4). In a number of places, mine personnel have protected the exposed culvert ends with slabs of sandstone. This appears to be an effective practice. King II • A fair amount of snow remains at King I, but bare ground is beginning to appear. • The East and West sediment ponds were no longer covered with snow and ice, and each one was impounding water. Neither pond was full enough to discharge. Primary spillways were clear and embankments appeared to be stable ROADS —Rule 4.03 Construction 4.03.1(3) /4.03.2(3); Drainage 4.03.1(4)/4.03.2(4); Surfacing and Maintenance 4.03.1(5) and (6)/4.03.2(5) and (6); Reclamation 4.03.1(7)/4.03.2(7): • Roads within King II were slightly muddy in spots, but were beginning to dry out(Photo 6). • It appeared that some minor grading may be necessary in order to restore surface drainage, now that winter is past. REVEGETATION—Rule 4.15 Vegetative Cover; Timing: The slopes above the Travelway Portal Structure (Photo 5) are bare of vegetation. Wire mesh has been draped over the steep, upper portions of the slopes. GCC said they would like to get some vegetation established on this slope. SUPPORT FACILITIES -Rule 4.04: King II(reference: Maps King 11005 and 007) • Petroleum products were stored in the 3-sided Fuel Storage Building. The water level in the containment pond behind the building had gone done somewhat since the previous inspection. The mine continues to haul potable water from Durango. The site for off-loading the water has been relocated from the pump house near the coal sales building to a portable pump located immediately below the water tank bench. • The shotcrete cut slope above the mine fan bench appears to be effectively holding the cutslope in place (Photo 6). SIGNS AND MARKERS —Rule 4.02: Permit Boundary signs were posted at regular intervals around the perimeter of the King 11 facilities. Mine identification signs were posted at the entrances to King I and King II. Number of Partial Inspection this Fiscal Year: 6 Number of Complete Inspections this Fiscal Year: 3 Page 4 of 9
