<br />~. <br />(Page 3) <br />NINE ID / OR PROSPECTING ID f H-80-244 <br />INSPECTION DATE 8-23-94 <br /> <br />INSPECTOR'S INITIALS ACS <br />A one-way road has been cut by the contractor to allow a return route for the belly dump <br />trucks that are being used to haul soil liner fill to the leach pad from the Ironclad-Globe <br />Hill Protect. This road ie located south and west of the Phase 1 pad. The road has been cut <br />through the topsoil horizon, and the cut material piled in a berm on the downhill side. Ae <br />discussed with Dave Kidd at the site, the Division ie concerned with contamination or lose <br />of the~topaoil resource with this kind of road. If this road is to be surfaced for long term <br />use, the topsoil should be segregated into a stockpile. CC&V ie directed to provide details <br />(brief) on the proposed use of this road, and its reclamation. <br />On monday, 8/22/94, fly rock from a bleat within the leach pad foot-print on the north aide <br />of Arequa Gulch had damaged exposed (not yet covered with select fill) geo-synthetic <br />installed over the primary underdrain. Underlying geotextile was also ripped in places where <br />fly rock had impacted. The contractor (Gundle) had removed all of the geomembrane that had <br />not been protected by a covering of fill at the time of the blast. Damaged areas of <br />geotextile were being patched at the time of this inspection. The contractor was directed <br />not to deploy new geomembrane until the patching operations were accepted by the engineer. <br />We returned to this location about an hour later to determine if this direction was being <br />followed, and it was determined that the geotextile patching and geomembrane re-deployment <br />operations were proceeding as specified. <br />In-ditch sediment controls along the haul road that goes from Highway 67 to the main topsoil <br />stockpile were inspected. Host of the sediment traps were filled to capacity. This <br />indicates two things: 1) The sediment traps are functioning ae intended, and 2) The road and <br />up-gradient disturbed area are producing a great deal of sediment. Sediment controls at the <br />Bite need to be inspected, and necessary maintainence completed after each significant rain <br />event. <br />The Ironclad tails/ soil liner source was inspected. The contractor has set-up a 3 inch <br />vibratory screen at this location. Hypochlorite ie being added to the Boil liner material <br />on the conveyor exiting the screen. Plastic sheets have been draped over this part of the <br />conveyor to diminish the strong chlorine odor associated with cyanide detoxification. A <br />dozer was pushing ironclad tails from the top of the pile to the screen plant. The tails at <br />the top of the pile generally contain lees residual cyanide than the tails at the base of the <br />pile. It is hoped that some natural cyanide degradation will occur as materials lower in the <br />pile are exposed. <br />No significant problems were noted during this inspection. The Division will closely <br />scrutinize oversize removal operations and sediment trap maintainence during future <br />inspections. <br />I & E Contact Addreae <br />NAHE John Hardaway <br />OPERATOR Crioyle Creek & Victor Gold <br />STREET P.O.
