(Page 2) MINE ID # OR PROSPECTING ID #: M198n-9dd INSPECTION DATE: .4-S.11 n INSPECTORS INITIALS: RK_ OBSERVATIONS The Division conducted a monitoring and construction progress inspection of the site on 4/5/10.On 4/3/10, the Division received a call from the Health Department( Mr. Dave Acres) about a complaint received by EPA, about a possible illegal discharge from the facility to underground workings. The site is a non discharging facility and the only underground discharge is at the Carlton Tunnel, which is an NPDES permitted discharge point. No other discharge to underground workings was noted during this inspection. The inspection began near the Phase V leach pad construction area. Grading of the old Areqau Gulch waste pile that will be part of the Phase V leach pad was continuing. The large underground workings near toe of the grading and under drain over lap area has been back filled with concrete. Inspected the clay borrow area. A large stockpile of the clay has been processed, in anticipation of clay liner deployment by the end of the month. Storm water drainage control in place. Inspected the Iron Globe Hill area. Tim stated that due to the new rules under Home Land Security, because of explosive storage on site, additional measures including video surveillance cameras, will be installed. Inspected the Cresson mine. South Cresson was active, at the time of the inspection. Backfilling of the East Cresson and wild horse area is continuing. Drainage control for the area was found to be in good repair. Inspected Phases IVC leach pad area where a leak was reported in February. Limited application of solution as approved during the site visit on March 2,2010,is continuing. Permanent remediation of the liner repair and drainage control for the area will be submitted by 6-30-10 as a technical revision. The following readings were collected from the high and low volume solution collection systems transducers for the pregnant ponds Phase I thru IV. Phase I High volume solution transducer # 1 was recorded at 30.8 #2 was at37.2 and # 3 was at 39.9. Piezometer for the pond, the true measure of the pond volume was at 53 feet. Low Volume solution collection transducer # 1 was recorded at .36 and # 2 was at .43 Phase II and III high volume solution collection transducer # 4 was recorded at 33.1 # 5 was at 24.0 and # 6 was at 38.2. Piezometer for the pond was at 33.5 feet. Low volume solution collection transducer # 1 was recorded at .14 and # 2 was at .59. Phase IV high volume solution collection transducer # 7 was recorded at22.7 # 8 was at 22.4 and # 9 was at 23.9 and # 10 was at 24.4. Low volume solution collection transducer # 1 was recorded at 12.9 and # 2 was at 10.1 inches of hydrostatic head( all other readings are in feet of hydrostatic head.) Inspected the external pond, it was holding a partially frozen water from the recent storms. Low volume solution collection transducer # 1 was recorded at 12.1 and # 2 was at 10.1 inches of hydrostatic head. Inspected the under drain area. Both the south and AG 1 were discharging at the time of the inspection. All lower ponds were holding some water from the recent storms the area recived. All ponds were well below discharge level.
