October 19, 2011 C -1981 -035 /King Coal Mine MLT Number of Partial Inspection this Fiscal Year: 3 Number of Complete Inspections this Fiscal Year: 1 Page 3 of 4 At the West pond, water covered an estimated 20 percent of the pond floor, at the north end, adjacent to the embankment. This pond is also equipped with a staff gauge. The outer slopes of the po nd embankment are well vegetated; the top surface and inside slope are less vegetated. The emergency spillway was clear and intact. The sediment pond at King II was empty, but the bottom was still wet. Mr. Jarvis said this pond received quite a bit of ru noff during the previous precipitation event, which brought the water level higher than it had been at any time during this season. With the dry, sunny conditions, however, the water had evaporated and/or infiltrated the ground below. Two new culvert pipe s had been installed in the facilities area at King II. The first was installed to enclose the collection ditch located against the hillside immediately east of the oil storage shed. The second has been installed below the rock dust silo, in an area that will eventually be paved over with concrete. During the August 2011 inspection, we observed a flow of water, unchecked, running down the slope from the water storage tank. A two -inch line has since been installed, to carry the back -flushed water safely d own the slope, without causing erosion. The irrigation ditch, from which water is drawn to fill the tank at King II, was shut off on October 1st. The mine is once again hauling water from Durango. This practice will continue until water is available in t he irrigation ditch next spring. ROADS – Rule 4.03 Construction 4.03.1(3) / 4.03.2(3); Drainage 4.03.1(4) / 4.03.2(4); Surfacing and M aintenance 4.03.1(5) and (6) / 4.03.2(5) and (6); Reclamation 4.03.1(7) / 4.03.2(7): The roads at King I were graded, and allowed easy access through the facilities and portal area and up onto the refuse pile. The roadway surface showed no unusual erosion, and the surface drainage appears to be good. The haul road at King II was in good condition. The surface was dry, and compacted sufficiently well that the breezy conditions were not generating fugitive dust. RECLAMATION SUCCESS - Rule 4.15, Rule 3: At King I, nearly all of the debris from demolition of the various facilities has been removed from the site.
