III. COMMENTS -COMPLIANCE Below are comments on the inspection. The comments include discussion of observations made during the inspection. Comments also describe any enforcement actions taken during the inspection and the facts or evidence supporting the enforcement action. Availability of Records Required records were on file and up-to-date through the 2'" Qtr., 2002. The records were checked by Dan Mathews of DMG the afternoon of July l 1. Mitchell Rollings had concluded his inspection prior to the records check. Roads Refuse Haul Road, Conveyor Access Road, and Water Tank Access Road had been previously treated with MgCI, and road surfaces remained stable with essentially no dust generation, despite the dry conditions. Drainage structures associated with the haul road and major access roads were properly maintained. Various riprap lined and rock check haul road ditch outlets had been properly maintained as requested since the previous inspection. The road ditch segment adjacent to "Treasure Island" entrance gate had been better defined as requested, The "sinkhole" feature, located on the light use road between the B Vent Shaft and RS-1 Shaft Site had not yet been filled in, and this work still needs to be done. The hole opening is approximately 3' by 2', and hole depth appeared to be approximately 6' to 8'. It is immediately adjacent to the road. Hvdroloeic Balance Most sediment ponds, and all SAE Sediment traps were dry. None of the ponds were discharging. At the refuse areas, Pond RP-2/3 still contained a shallow pool of water in the west inlet cell; the main cell and southeast inlet cell were both dry. SE inlet cell is largely filled in with sediment, and a track hoe was parked at the site. Operator indicated excavation of the inlet cell would be initiated shortly. There was a shallow pool in Pond RP-4, water level approximately 6' below top of riser. Pond RP-1 was dry, sediment level approximately 6' below top of riser. Pond RP-SA was also dry, sediment level approximately 5' below primary spillway elevation. At the D Portal Area Pond DP-1, water level had been pumped down to approximately 5' below the top of riser, and excavation of sediment from the upper end of the pond had been initiated. A quantity of sediment had already been hauled to the refuse areas for disposal, and additional material that had been pushed up into several piles in the pond vicinity was likewise to be disposed of. Both Slot Storage Ponds were dry, with sediment level in SS-1 approximately 2 feet below top of riser and SS-2 approximately 4' below fop of riser. Processing Pond PP-2 contained a shallow pool of water. A small area of the pond liner on thewest bank was exposed, and protective soil cover will need to be replaced. Upper end of the ditch that runs along the bench to the NW of PP-2 needed to be better defined to ensure sufficient grade.
