There was no evidence of erosion or instability along pond embankments. The pond was frozen, but the <br />pump was free of obstructions/debris time of the inspection. <br /> <br />PROCESSING WASTE/COAL MINE WASTE PILES – Rule 4.10 and 4.11 <br />Drainage Control; Surface Stabilization; Placement: <br /> During the inspection the RP-2/3/4 Refuse Pile was observed to be stable. Minor erosion rills on the slopes <br />of the pile have been noted in previous Division inspection reports and have not enlarged in a significant way. <br />Minor amounts of snow are present on the northern embankments of the stack. <br />The RP-5a Pile appeared stable during the inspection. Erosion on the slopes of the pile has been noted in previous <br />Division reports. Similar to the RP-2/3/4 Refuse Pile, these rills have not enlarged since the previous inspection. <br />There were no signs of displacement or slumping on the refuse pile. Minor amounts of snow are present on the <br />northern embankments of the stack (Photo 10). <br /> <br />ROADS – Rule 4.03 <br />Construction 4.03.1(3)/4.03.2(3), Drainage 4.03.1(4)/4.03.2(4), Surfacing and Maintenance4.03.1(5) and <br />(6)/4.03.2(5) and (6), Reclamation 4.03.1(7)/4.03.2(7): <br /> The Haul Road was clear and well maintained. There we no sections with ruts or other road damage. The <br />road surface had minor amounts of dust being generated behind haul trucks. The ditches that parallel the roads <br />appear to be stable and able to convey water. Some of the auxiliary roads had minor amounts of snow. A new gate <br />was placed at the beginning of the access road to the RP-1 Pond to discourage unauthorized entry (Photo 11) <br />CR-65 had no surface cracks or other indications of road damage due to subsidence. Access roads throughout the <br />mine site were traversed during the inspection. Roads were stable and no erosional features were identified. <br /> <br />RECLAMATION SUCCESS - Rule 4.15, Rule 3: <br /> The RP-1 refuse pile has been reclaimed for several years. Vegetation is well established and protects the <br />pile. No indications of instability of erosion were observed. The perimeter diches appear stable with no erosion <br />concerns. <br /> <br />SUPPORT FACILITIES - Rule 4.04: <br /> Support facilities that were inspected include the main facilities/portals area, B Seam Vent Shaft #1, RDH- <br />2, RDH-4, the conveyor corridor, and Slot Storage. The main facilities for the Deserado mine are composed of <br />three benches. The lower bench contains the mine, office, shop, and portals. The middle bench contains the prep <br />plant, and the upper bench contains a materials laydown yard and electric substation. The drainage structures in <br />the main facilities area were functioning correctly. There were no indications of erosional features on the three <br />benches and berms were in good condition. The safety fence surrounding the electric substation was in good <br />condition. <br />The B Seam Vent Shaft #1 is located north of the main facilities off of the haul road. The pad was stable with no <br />erosional features. The fencing around the shaft to prevent unauthorized entry was in good condition.
