The photographs were reviewed by Robin Reilley for <br />this report. Both Mr. Ranney and Ms. Reilley are employees of the Division of Reclamation Mining and <br />Safety. The photos were taken under mostly sunny conditions. At higher elevations the soil appears <br />saturated and muddy. The imagery captured the stockpiling of machinery for auction, a portion of the <br />numerous drill pad locations and a selection of hydrologic conditions on the mine site at the time. <br />HYDROLOGIC BALANCE Rule 4.05: <br />Drainage Control 4.05.1, 4.05.2, 4.05.3; Siltation Structures 4.05.5, 4.05.6; Discharge Structures <br />4.05.7; 4.05.10; Diversions 4.05.4; Effluent Limits 4.05.2; Ground Water Monitoring 4.05.13; <br />Surface Water Monitoring 4.05.13; Drainage Acid and Toxic Materials 4.05.8; Impoundments <br />4.05.6, 4.05.9; Stream Buffer Zones 4.05.18: <br />The following items may have already been addressed. However, since this recent inspection was an <br />aerial inspection on the ground verification did not occur. I list the following items here for tracking <br />purposes. Maintenance issues identified in previous inspection: <br />• Pond Al exhibited a cone of sediment debris at the outlet. <br />• There is some gullying from road drainage into ponds B and Al. <br />• Currently there is a mine pipe at Power Line Road conveying cables. This should be removed. Ditch D3 Lower is <br />somewhat compromised in a couple of areas from Powerline Road to the Washbay and Oil Storage area due to gravel that <br />was deposited. Some ditch maintenance is needed along here to maintain function. <br />These items seem to have been addressed as per aerials: <br />• Debris and equipment in Ditch D9 (clean water ditch) will require removal. The top of the ditch <br />surface requires leveling to ensure function and approved design is maintained. <br />Ponds B and D contained water, (Photo 1). The debris and equipment in Ditch D9 (clean water ditch) <br />noted in Photo 5 of the March 2015 inspection appears to have been removed (Photo 4).
