September 26, 2011 C- 1981- 044/Williams Fork Mines JRS <br />HYDROLOGIC BALANCE (cont.) - Ponds 5 -P5, 5 -P6 and 5 -P7 are the series of ponds that treat the water <br />pumped from the Mine No. 5 workings. These ponds all appeared to be full at the time of the inspection and <br />appeared to be discharging into the Williams Fork River. The pond embankments were all well vegetated and <br />appeared to be stable. In past inspections it has been noted that there was a large burrow in the north embankment <br />of pond 5 -P7 that needs to be filled in. It was difficult to determine if this burrow has been filled in but the 3QI 1 <br />sediment pond inspection report stated that it was. This will be checked in the Division's next inspection. <br />- Sediment Ponds 5 -P 1, 5 -P2 and 5 -P3, which are along the rail loop, were all dry at the time of the inspection. <br />All of the pond embankments were well vegetated and appeared to be stable. No erosional problems were noted <br />on any of the embankments. <br />- Sediment Pond 9A -P 1, which is in the Williams Fork Strip Pit, was dry at the time of the inspection. The pond <br />embankment appeared to be well vegetated and stable and no erosional problems were noted. <br />ROADS — Rule 4.03 Construction 4.03.1(3)/4.03.2(3) Drainage 4.03.1(4)/4.03.2(4) Surfacing and <br />Maintenance4.03.1(5) and (6)/4.03.2(5) and (6) Reclamation 4.03.1(7)/4.03.2(7): <br />- The mine entrance road appeared to be stable and well maintained at the time of the inspection. The haul road on <br />the west side of Colorado Highway 13 also appeared to be stable and well maintained. No erosional problems <br />were noted on these road segments. <br />RECLAMATION SUCCESS - Rule 4.15, Rule 3: <br />- There has been a Russian knapweed infestation on several areas of the mine. These areas include along the haul <br />road on the west side of Colorado Highway 13, on the 5 -P5, 6 and 7 pond embankments, south of the coal <br />stockpile area, behind the Mine No. 9 refuse pile and in the field by ponds SH -P 1 and 2. The operator has <br />reported that these areas were recently sprayed. It was difficult to determine the success of these spraying <br />activities from the photographs. The areas will be looked at closely during the Division's next inspection. <br />- The reclaimed Williams Fork Strip Pit is well vegetated and stable. There were no erosional problems noted in <br />the reclamation. There were several patches of Russian knapweed noted in the pit (on the south side of the <br />reclamation). These areas will be looked at during the Division's next inspection. <br />SUPPORT FACILITIES - Rule 4.04: <br />- The mine No. 5A portal and facilities area appeared to be stable at the time of the inspection. No erosional <br />problems were noted. It does appear that the rock dust tank, which was just north of the multiple services <br />building, has been removed. Brian Watterson has stated that the operator planned to remove the tank and use it at <br />the Twenty Mile Mine in Oak Creek. <br />- The Mine No. 5 facilities area also appeared to be stable at the time of the inspection. The area where facilities <br />were removed remains stable. No problems were noted in the Mine No. 5 facilities area. <br />DOCUMENTS RECEIVED: None <br />Number of Partial Inspection this Fiscal Year: 2 <br />Number of Complete Inspections this Fiscal Year: I <br />Page 3 of 7 <br />
