August 19, 2014 C-1980-007/West Elk Mine JHB <br /> <br /> <br />State Highway 133, in cooperation with CDOT. While observing the construction of the under drain, a truck <br />dropped of a pile of large gravel sized rock (photo 4) for use in the under drain as well. Jessica said that the fabric <br />will be wrapped over the drain rock prior to covering with refuse (gob) material. <br /> <br />The surface of the top of the RPEE was damp. MCC has graded the pile to allow drainage to the side ditch DRPE. <br />No problems were identified with this surface inspection of the RPEE. <br /> <br />MCC has re-possessed refuse from the LRP. The area of re-disturbance is directly north of the prep plant. The <br />excavation is approximately 8-12 feet deep. Currently a depression has been left. The depression does not exceed <br />the northern edge of the top of the pile. Drainage from this area will continue to be routed to the west. MCC will <br />evaluate if additional material may be accessed. <br /> <br />ROADS Rule 4.03 <br />Construction 4.03.1(3)/4.03.2(3) <br />Drainage 4.03.1(4)/4.03.2(4) <br />Surfacing and Maintenance4.03.1(5) and (6)/4.03.2(5) and (6) <br />Reclamation 4.03.1(7)/4.03.2(7): <br /> Roads throughout the mine site were dry and well maintained. <br /> <br />REVEGETATION Rule 4.15 <br />Vegetative Cover; Timing: <br /> Revegetation was discussed in the Processing Waste section. Road cuts in Sylvester Gulch have had <br />stabilizing vegetation established. Overall MCC has been effective in weed control measures. Few noxious weeds <br />were observed. When noxious species were observed, primarily Bull thistle, it was limited to individual plants. <br />Cheatgrass appears to be fairly well controlled as well. <br /> <br />TOPSOIL Rule 4.06 <br />Removal 4.06.2; Substitute Materials 4.06.4(4); Storage and Protection 4.06.3; Redistribution 4.06.4: <br /> LRP Topsoil stockpile and RPE Topsoil stockpile both had a flush of annual mustard on the south facing <br />slope and top of the piles. Ms. Loveland noted that MCC had treated these piles for Cheatgrass in 2013. While the <br />presence of annual mustard species is not a problem, closer observation of the LRP topsoil stockpile found some <br />Cheatgrass still present under the mustard. Few perennial species were present in this area to compete with the <br />is concerned that control of the Cheatgrass, or die-off of the annual mustards will <br />leave a disturbed area that will allow invasion by weedy species. Knocking down of the annual mustard and <br />application of topsoil stabilization seed mix may allow for establishment of the desired perennials and minimize <br />reinvasion of the weedy species. <br /> <br />The LRP and RPE topsoil stockpiles were not exhibiting rilling or gullying, and aside from the small areas of <br />Cheatgrass, few noxious species were noted. Several Bull thistle plants had established on LRP topsoil stockpile. <br /> <br />The Sylvester Gulch facilities topsoil stockpile had good vegetative cover, was not weedy, and showed no <br />evidence of rilling or gullying. <br />Number of Partial Inspection this Fiscal Year: 2 <br />Number of Complete Inspections this Fiscal Year: 0 <br /> <br />46 <br />Page of <br /> <br /> <br />
