April 7,2011 C-1 981-044/Williams Fork Mines JRS HYDROLOGIC BALANCE(coot.)—The mine discharge ponds(5-P5, 5-P6 and 5-P7)were all about half full at the time of the inspection and not discharging. The Mine 5 pump has been down and needs to be replaced. Joe Shoemaker indicated that a new pump has been ordered but had no timeframe for its replacement. The wells and pump are located just east of the outfall from Pond 5-P7. The pond embankments were all well vegetated and stable and no erosional problems were noted. -Ponds HR-P 1 a,HR-P 1 b and HR-P2 all contained water but were not discharging at the time of the inspection. These ponds are partially incised ponds,with small embankments. The pond embankments were well vegetated and stable and no erosional problems were noted. -Williams Fork is still planning on replacing the riprap material along the bank by the supports for the rail bridge. This work will be performed by a Seneca crew. The work is planned for the next few weeks,hopefully before the river reaches high-flow. The operator must be careful to ensure that all of the riprap remains on the river bank and does not go into the Williams Fork River. PROCESSING WASTE/COAL MINE WASTE PILES—Rule 4.10 and 4.11 Drainage Control; Surface Stabilization; Placement: -The reclaimed refuse pile remained stable at the time of the inspection. The area is basically flat and there were no signs of erosion. The pile appears to have positive drainage,as no water was pooled on the surface. This will be the second growing season so there should be more perennial grasses on the reclamation this year. -The remaining active refuse pile was also stable at the time of the inspection. The pile appears to have positive drainage, as no water was pooled up on the pile. -The operator has cut a small dozer blade-width slot in the permitted solid waste disposal area for the disposal of mine-related debris. The material from the slot is stockpiled on either end of the pile and will be used to fill in the slot once it is no longer needed. ROADS—Rule 4.03 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(6)/4.03.2(5)and(6)Reclamation 4.03.1(7)/4.03.2(7): -The mine entrance road was mostly stable and well maintained at the time of the inspection. There was one area, however,that did have some erosion off of the edge(possibly started from a burrow). The area was on the bridge/fill area on the east side of the site,just south of the 7-north angle well house. The erosion was approximately 1/3 of the way across the bridge/fill on the west side of the road. This area will need to be repaired to keep it from becoming a problem and causing instability in the road. -The light-use road behind the coal stockpile/stacking tube and coal silo area was stable and in good condition at the time of the inspection. No erosional problems were noted on this road segment. -The light-use road that runs through the hay field on the west side of the mine to the river and rail bridge was also stable at the time of the inspection. There was some slight rutting along the road but it does not appear to be a problem at this time. RECLAMATION SUCCESS—Rule 4.15, Rule 3: -Williams Fork will need to perform weed spraying on all of the mine areas,including the Williams Fork Strip Pit,to try and knock back the Russian Knapweed infestation that has occurred. A number of the areas were identified in inspection reports last year but the operator should walk the entire site to ensure that all of the areas have been sprayed.
