March 24, 2011 C-1981-044/Williams Fork Mines JRS <br /> HYDROLOGIC BALANCE(cont.) -Williams Fork is planning on adding additional riprap along the bank of <br /> the Williams Fork River by the supports for the rail bridge. Last runoff season some brush got stuck and caused a <br /> part of the area to be eroded. This riprap will be placed by the supports to help protect them from further erosion. <br /> -The 7-North Angle Well house and surrounding area were stable and in good condition. This well has not <br /> operated since the mine went into temporary cessation. <br /> -Pond 5A-P1 contained a small amount of water and was not discharging at the time of the inspection. The pond <br /> embankment was well vegetated and stable and no erosional problems were noted. <br /> -Ponds 5-P5, 5-P6 and 5-P7 are treatment ponds for the portal discharge(from pumping the portals). The water <br /> level in these ponds was very low and they were not discharging at the time of the inspection. Joe Shoemaker <br /> indicated that the pump died and Williams Fork has not been able to repair it. The pond embankments were <br /> covered with snow but appeared to be stable. No erosional problems were noted. <br /> PROCESSING WASTE/COAL MINE WASTE PILES—Rule 4.10 and 4.11 Drainage Control; Surface <br /> Stabilization; Placement: <br /> -The reclaimed refuse pile area remained stable at the time of the inspection. The area was covered with snow. <br /> -The remaining refuse pile was also covered with snow at the time of the inspection. <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 Maintenance 4.03.1(5)and <br /> (6)/4.03.2(5)and(6)Reclamation 4.03.1(7)/4.03.2(7): <br /> -The haul road was plowed at the time of the inspection. The road was well maintained and stable. <br /> RECLAMATION SUCCESS—Rule 4.15,Rule 3: <br /> -Williams Fork has completed the removal of the fuel tanks from the bulk fuel and oil storage building at the 5A <br /> portal area. They are also planning on removing the rock dust tank at this area and moving it to the twenty Mile <br /> Mine. <br /> -Last year the Division noted Russian Knapweed problem areas at the Williams Fork Mine. Moffat <br /> County Mining will need to spray these areas and perform a detailed survey of the entire mine area this <br /> spring to help combat this problem. Moffat County Mining will also need to spray the weeds in the fall. <br /> This twice a year spraying will be needed until the knapweed has been knocked back. <br /> DOCUMENTS RECEIVED: None <br /> This concludes the Division's 24 March 2011 inspection report for the Williams Fork Mines. <br /> Number of Partial Inspection this Fiscal Year: 4 <br /> Number of Complete Inspections this Fiscal Year: 3 <br /> Page 3 of 7 <br />
