December 19, 2017 C-1981-038/Bowie No. 1 Mine CCW <br /> <br /> <br />Number of Partial Inspection this Fiscal Year: 6 <br />Number of Complete Inspections this Fiscal Year: 2 <br /> <br /> Page 3 of 6 <br /> <br />- Binwall Pond 3: <br /> The regraded slopes were stable and in good condition. The slopes had no indications of erosion. The straw <br />mulch was being held in place by the rocks placed on top. The straw mulch was in good re pair. The reestablished <br />channel at Pond 3 was stable. There was evidence of flows since the channel was completed. There was not any <br />water in the channel at the time of the inspection. The channel had not down -cut or eroded the banks. <br /> <br />- Binwall Pond 4: <br /> Binwall pond 4’s regraded hill slopes were in good repair and there was no evidence of erosion. The straw <br />mulch was stable and the rocks placed on top were functioning well to stabilize the straw. The reestablished <br />channel was in good condition. There was evidence of flow since the channel was completed. The channel was <br />dry during the inspection. The channel did not exhibit any down -cutting or erosion of its banks. The outlet to the <br />reestablished channel has sediment control features in place. There are hay bales staked into the center of the <br />channel and silt fencing goes up the slopes on both sides of the channel. The sediment control features were in <br />good condition at the time of the inspection. The hay bales were securely staked into the channel and the silt <br />fences were intact. <br /> <br />- Waste Pile Pond / Gob Pond (Photo 2): <br /> The Waste Pile Pond was backfilled and regraded in August 2017. The regraded contours were stable and there <br />was no evidence of erosion. The straw mulch on top of the site was in good condition and the rocks placed on top <br />were working to hold the straw in place. The reclaimed contours blended the pond into the surrounding hillslope. <br />The runoff from the site is treated by sediment control measures put on the lowest c ontours of the site. The <br />sediment control measures are silt fences, berms and sediment logs. The berms and silt fencing were observed to <br />be intact and functioning as designed. The sediment logs were also in good condition and functioning as designed. <br />T he sediment logs were placed behind the silt fence on the lowest contours of the site. Undercutting of the <br />sediment logs had not occurred. <br /> <br />- ROM Pond: <br /> The ROM Pond was backfilled and regraded during the month of August 2017. The site was stable and there <br />were no erosional features identified. The contours of the pond allow for the runoff of the area to be <br />treated by silt fencing, berms and hay bales at the lowest contour elevation of the site. The berms were in good <br />condition and there were no areas where runoff had breached. The silt fencing was in good repair and capable of <br />functioning as designed. The hay bales were placed at the lowest point of the site. The hay bales were observed to <br />be firmly staked into the ground and capable of functioning as designed. <br /> <br />For details on the hydrologic balance of the Loadout Pond, please see the Support Facilities On -Site section of this <br />report. <br />
