The inspection began in Arequa Gulch, where GW samples were collected for Sulfate and wad cyanide analysis from compliance wells CRMW 3A AND 3B. Samples were collected in accordance with EPA guidelines for water sampling. Four case volumes were purged before a sample was collected. Operator collected a split using their own bottles. while in the area, inspected the under drain. All lower ponds were dry. Water samples for wad cyanide analysis, with a split for the operator were collected from the South under drain, which was flowing at 8 gpm and 4 inch pipe or AG 1 which was flowing at 0.8 gpm. inspection began around the Phase IVC perimeter liner inter phase ditch area. The west facing pads were being leached at the time of the inspection. The inter phase ditch area was walked and inspected and found to be in good repair. Continued the inspection to Phase I pregnant pond and leach pad area area. It was active at the time of the inspection. While in the area collected the following readings from the high and low volume solution collection transducer for Phase I,II,III&IV. Phase IV High Volume Solution Collection transducer # 7 was recorded at29.5 # 8 was at 29.4 #9 was at 28.9 and # 10 was at 29.8. Low volume solution collection transducer # 1 was recorded at 12.4 and # 2 was at 10.4 inches of hydrostatic head. Phase I high Volume solution Collection transducer # 1 was recorded at 22.4 # 2 was at 30.3 and # 3 was at 27.3 piezometer for the pond was recorded at 34.3.0. Low volume solution collection transducer # 1 was recorded at .34 and # 2 was at .44. Phase II & III High Volume Solution Collection Transducer # 4 was recorded at 38.2 #5 was at 29.4 and # 6 was at 39.3. Low volume solution collection transducer # 1 was recorded at.55 and # 2 was at.23 Piezometer for the pond was recorded at 41.7. Low volume solution collection pressure transducer # 1 was recorded at 0.56 and # 2 was at 0.24 Inspected the external pond it was holding about the same amount of water as noted during the last inspection. Low volume solution collection transducer # 1 was recorded at 11.6and # 2 was at 9.6 inches of hydro static head. ' Inspected the Phase V leach pad construction area. Leak Collection gravel along the Eastern portion of the pregnant pond, drain cover along the west, and north side of the pregnant pond and gemembarne along the south and North Eastern portion of the pregnant pond area were being deployed at the time of the inspection. Amec QA/QC personnel were on site observing the deployment as required. The western portion of the pregnant pond area is almost covered with drain cover material. CC&V anticipates placing the riser pipe caisson if all the material required for placement of these 5600lbs each, riser pipe caisson is delivered on site, they will anticipate placing them on Monday, 9/20/10 Inspected the Cresson mine, main Cresson mine was active at the time of the inspection.
