ORIGINAL -PUBLIC FILE <br />(Page 2) <br />MINE ID # OR PROSPECTING ID #: ti+-Iean-yea <br />INSPECTION DATE: 7/~~W4 INSPECTOROS INITIALS: ~,~ <br />OBSERVATIONS <br />The Division conducted a weekly construction progress of the Phase IVC <br />leach and area and a monitoring inspection of the site on 7/22/04. <br />Inspected the Phase IVC leach pad area. The area had received some rain the <br />after noon of 7/21/04, which made the clay and geomembrane deployment <br />difficult, still approximately 120,000 square feet of liner was deployed, <br />since the last inspection. The deployed liner was inspected and appeared to <br />meet the required specifications. <br />Drain cover was being deployed along the NORTH WEST facing slopes at the <br />time of the inspection. Golder QA/QC in addition to Ames workers were <br />present over looking the deployment. Given the amount of rain that had <br />fallen in the month of July, the pad acres did not have show any noticeable <br />ponding of water or solution. <br />Inspected the phase I, II, III AND IV leach pad pregnant POND areas and <br />recorded the following readings from the High and Low volume solution <br />collection transducers. <br />Phase I High Volume solution collection transducer # 1 was recorded at 32.2 <br />#2 was at 28.8 and # 3 was at 28.0. Low volume transducer # 1 was at .17 <br />and # 2 was at .53. Piezometer for the pond was at 34 feet. <br />Phase II and III High Volume solution collection transducer # 4 was <br />recorded at 34,9 # 5 was recorded at 27.9 and # 6 was recorded at 37.4. Low <br />volume transducer # 1 was at .12 and # 2 was at .46. Piezometer for the <br />pond was at 37,1 feet. <br />Phase IV High Volume solution collection transducer #7 was recorded at 20.8 <br /># 8 was at 19.9 # 9 was at 20.7 and # 10 was at 20.1. Low volume transducer <br /># 1 was at 10.6 and # 2 was at 7.6 inches of hydrostatic head. (All other <br />readings are in feet of hydrostatic head) <br />Inspected the external pond, it was holding some water (rain). While in the <br />are recorded the following readings from the Low Volume collection <br />transducers. Transducer # 1 was at 12.7 and # 2 was at # 7.6 <br />Inspected the under- drain area, all the ponds including the surface water <br />diversion sumps were holding water. All ponds appeared to be functioning as <br />designed and no major problem noted. Both the South, North and 4-inch pipes <br />were discharging at the time of the inspection. <br />
