October 15, 2014C-1996-083/Bowie No. 2 MineSLB <br />weresteepened. The operator extended the rip rap from ditch F21 upgradient to ditches F18, F19, and F20 to <br />ensure that the transition zones remain stable. The rip rap material was well graded and the installation properly <br />executed. <br />The upper bench of Gob Pile #4 needed to be graded to drain to ditches F18 and F19, to ensure that water is <br />not impounded on the top of the pile. <br />There was a gully, approximately 12-18”deep extending down the face of <br />Gob Pile #4, between ditches F19 and F3. The pile should be graded to ensure that flow is routed to either ditch <br />F19 or F3, and not over the outslope of the bench, as required by Rule 4.09.2(5). <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 Maintenance <br />4.03.1(5) and (6)/4.03.2(5) and (6), Reclamation 4.03.1(7)/4.03.2(7): <br />Light use roads to the gob vent boreholes and Terror Creek fan site were in good condition. Wattles were in place <br />Wattles and straw logs at the road crossing over <br />at drainage runout points and were generally in good shape. <br />the confluence of the East and West forks of TerrorCreek were in need of maintenance <br />; sediment was built <br />up behind the structures such that they may not be effective in a significant precipitation event. Placing additional <br />wattles on the southeast side of the road, upgradient of the crossing, might reduce the amount of sediment <br />collecting at the low point above the West Fork. <br />REVEGETATION –Rule 4.15Vegetative Cover; Timing: <br />Several gob vent boreholes, borehole 2014-SS-B, and both Terror Creek flume installation sites were seeded this <br />past spring and early summer. Perennial grasses and forbs had germinated on all of the seeded areas and were <br />becoming well established. <br />Gob vent boreholes -B14A, -B14B, and -B14C had been seeded and mulch mat had been installed (-B14C was not <br />yet completed -about 25% of the reclaimed area had not been covered with mat). <br />The Pitkin Mesa Pipeline relocation corridor, also seeded this past spring, exhibited several species of perennial <br />grasses and forbs. The pipeline corridor is also rife with Bull thistle, both mature plants and new rosettes; the <br />apparent seed source is the undisturbed area adjacent to the corridor, also exhibiting a dense population of thistle. <br />BRL should endeavor to treat the Bull thistle along the Pitkin Pipeline relocationthis fall to gain an <br />advantage next spring. <br />Canada and Bull thistle were observed in several areas sitewide, including the gob vent boreholes and GVB roads <br />over Panels 14, 15, and 16, the east and west diversion ditches of GobPiles #2/#4, the south end of the Hubbard <br />Creek fan site, on the utility bench above the main fan, and at the storage yard west of the loadout conveyor. <br />These areas should be also be treated this fall, if weather conditions allow. <br />During the inspection, Gary <br />Harding removed several Bull thistle plants that were observed on the topsoil stockpile at GVG-B15A. <br />Houndstongue was observed at the Terror Creek fan site and the “Yard in the Sky” outslope. <br />Cheatgrass was observed on the east side of Topsoil Stockpile F and the south side of Topsoil Stockpile A. <br />Number of PartialInspection this Fiscal Year: 3 <br />Number of CompleteInspections this Fiscal Year: 2 <br />937 <br />Page of <br />
