Aerial <br />photos were taken by Harry Ranney of CDRMS on May 3, 2012. Images were downloaded on May 7, 2012. <br /> <br />The weather appeared clear and dry based on the aerial images. The aerial images focused on the areas previously <br />identified by the surface landowner as having subsidence features. These features are located west of the RDA, <br />and east of Fremont County Road #15 near the Thompson Ranch buildings. <br /> <br />PROCESSING WASTE/COAL MINE WASTE PILES Rule 4.10 and 4.11 Drainage Control; Surface <br />Stabilization; Placement: <br />No instability or gully formation was observed from the aerial photo of the RDA. <br /> <br />SUBSIDENCE Rule 4.20: <br /> The aerial photos were taken of the area of the mine from the Thompson Ranch buildings on the South <br />north to FCR #15 in the vicinity of the previously identified subsidence holes. 6 holes were documented in <br />December 2011 located east of Newlin Creek and South of the reconstructed drainage at a reclaimed surface pit <br />located south of the Thompson Ranch driveway. <br /> <br />The landowner has expressed concern regarding trespass motorcyclists entering property near the subsidence <br />holes. Dirt paths were visible from the aerial photos in the grassy areas near the subsidence holes. <br /> <br /> The holes are in a heavily wooded bounded on the west by Newlin Creek. Newlin Creek bed is very rocky with <br />steep rocky banks. It would be highly unlikely that trespass vehicles could enter the subsided area from the west. <br /> <br />Dirt paths are also noted to the NW of the holes in the grassy area between county road #15 and the wooded <br />Newlin Creek bed area. These tracks do not enter the wooded area and remain on the north side of Newlin Creek. <br />Number of Partial Inspection this Fiscal Year: 9 <br />Number of Complete Inspections this Fiscal Year: 3 <br /> <br />26 <br />Page of <br /> <br /> <br />
