The pond was dry at the time of the inspection. <br />No other indications of erosion were observed. The outlet was clear of obstructions. <br />The Raw Water Lagoon is in the southeastern portion of the permit boundary off CR-65 and adjacent to the White <br />River. There was no evidence of erosion or instability along pond embankments. The pump was free of <br />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 /> The RP-2/3/4 pile was stable. The operator has recently graded the slopes of the stack to remove erosional <br />rills the previous inspection. <br />The RP-5a pile appeared stable during the inspection. Minor rills have appeared on the slopes of the pile since the <br />operator graded in June (Photo 7). <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 was being watered and no noticeable amount of dust was generated by haul trucks. The ditches that <br />parallel the roads appear to be stable and able to convey water. <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 (Photo 8). <br /> <br />SUPPORT FACILITIES - Rule 4.04: <br /> Support facilities that were inspected include the main facilities/portals area, B-Vent Shaft #1, RDH-3, <br />radio tower/water tank, and the conveyor corridor. 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 material laydown yard is well kept and organized. The safety <br />fence surrounding the electric substation was in good 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 (Photo 9). The fencing around the shaft to prevent unauthorized entry was in good condition. <br />The pad for RDH-3 rock dust tank is located on the north side of the B Seam Dewatering System #1. The pad for <br />the tank was stable with no indications of erosion.
