November 8,2010 C-1981-017/Coal Basin Mines SGR <br /> significant slide of altered shale material has closed the road at this location. Road F, and Mine 3,are only <br /> accessible by foot or horseback from this point. This failure appears to be a gravitational release of the weathered <br /> shale,versus a slump block triggered by the summer rainstorm. No evidence of spring or seep flow from the toe <br /> of the slide was observed. Road F was walked for another half mile or so. The ephemeral stream crossing located <br /> before the first switchback has down cut, also limiting travel. <br /> Road G,which accesses Mine 5 from the Road E/F/G intersection,was inspected from the intersection to the <br /> Oil Well Creek low water crossing. The road was functioning as designed for this distance. Oil Well Creek has <br /> down cut through the low water crossing,but not on the scale observed at other areas. Snow cover and channel <br /> scour prevented further access toward Mine 5. <br /> SUPPORT FACILITIES -Rule 4.04: <br /> Mines 1 and 2 were observed. The former access routes to the Mine 2 bath house and to the Mine 2 <br /> beltline entry were walked. These areas are functioning as designed. <br /> The former Mine 1 loadout bench located immediately down slope and east of the former mine entries, <br /> experienced significant runoff,presumably as a result of the rain event that so significantly scoured Dutch Creek. <br /> It is apparent that a tremendous amount of surface water runoff transited the area,and then cascaded down the <br /> Mine 1 outslope. This event caused significant erosion to the outslope. Two large gullies have developed at the <br /> outslope. The tree bands planted in the late 1990's and early 2000's are visible from the Mine 1 bench. Some <br /> amount of remedial work may be accomplished at the Mine 1 bench in the early summer of 2011. Any work <br /> undertaken at this location would be geared toward dispersing overland flows to minimize the potential for erosive <br /> flows from flowing over the outslope. It should be noted however,that similar work has been previously <br /> attempted on a number of occasions. <br /> SEALING OF DRILLED HOLES AND UNDERGROUND OPENINGS—Rule 4.07 <br /> RECLAMATION PLAN COMPLIANCE—Rule 4.13 <br /> DOCUMENTS RECEIVED <br /> OTHER(SPECIFY) <br /> Number of Partial Inspection this Fiscal Year: 0 <br /> Number of Complete Inspections this Fiscal Year: 1 <br /> Page 4 of 7 <br />
