June 21, 2012 C-1981-018/Deserado Mine ZTT <br /> <br /> <br />The dewatering pump was not operating during the time of the inspection. Oil curtains have been installed to help <br />control oil within the water being pumped. Additional rip rap was added at transfer points between each cell. All <br />embankments were stable and vegetation is starting to grow from the recent seeding on top of the topsoil piles <br />between ponds. <br /> <br />The Raw Water Lagoon was inspected. Embankments were well vegetated and stable. Water was being pumped <br />from the lagoon up to the Raw Water Tank. The lagoon was also being recharged by a second pump pumping <br />from the river into the Raw Water Lagoon. <br /> <br />HRB-2, HRB-3 and Explosive Storage SAEs were inspected for proper sediment control measures. Each SAE is <br />surrounded by berms diverting runoff to constructed rock check dams. No major signs of erosion were present and <br />all check dams were stable. <br /> <br />Water Storage Tank, Radio Tower, RDH-2 and B-Vent Shaft #1 and #2 SAEs were constructed with gravel pads <br />for sediment control measures. Each SAE were well graded with gravel and no major signs of erosion were <br />present. <br /> <br />B-Vent Shaft #3 still needs gravel to be spread around the area. No signs of erosion on the vent pad were <br />observed. <br /> <br />Transfer Stations #1 and #2 were inspected. All runoff from these facilities are directed to ditches and eventually <br />to ponds. Transfer Station #2 has runoff partially directed to two washdown sumps. Both sumps were dry. <br /> <br />Mine Dewatering Pond 1 with oil curtain. Sedimentation Pond DP-1. <br /> <br />GENERAL MINE PLAN COMPLANCE: <br />Large diameter CMP has been stored along the access road to the B-Vent Shaft #1. It appears these pipes are <br />outside of the disturbed area boundary and will need to be removed from the area. <br />Number of Partial Inspection this Fiscal Year: 8 <br />Number of Complete Inspections this Fiscal Year: 4 <br /> <br />35 <br />Page of <br /> <br /> <br />
