At 0800 hrs. I arrived on the mine site and met Ron Zumwalt, Safety Superintendent, San Luis Mine. We toured the mines pit and tailings impoundment. We met with Jim Willshau, Owner of SLV Earth Movers, Inc., the contractor for reclamation. At 0920 hrs. Mr. Jim Dillie, Colorado State, arrived on site. After a tour of the tailings impoundment and the east ar.~d west pit areas, Mr. Willshau, Mr. Zumwalt, Mr. Dillie and I discussed the future reclamation plans and design of the tailings impoundment spillway. Mr. Dillie stated that he was primarily concerned that there be no breaches in the liner at the tailings impoundment, tY,~at a half percent fall be designed from the east end of the tailings impoundment to the spillway, that a review and approval by the state agencies be done, after the design for water shed run-off across the tailings from the south was completed and that the design for the spillway be reviewed and approved by the state agencies prior to construction, in the area of the west pit, he stated that, he had no concerns that the drainage from this area be located wherever it was practical and not necessarily where shown on the reclamation plan. He further stated that he had no problem with event ponding with a standpipe to a culvert crossing beneath the county road for relief, as long as there was sediment control and water flow velocity dissipators prior to reaching the creek. He reviewed the buttressing of the north end of the pit in progress and stated that where necessary buttressing in the pit could be done where deemed appropriate as long as those areas defined for reclamation were completed. The reclamation contractor attempted to cross the northern portion of the tailings with a 325 (CAT) track-hoe which became bogged down. Attempts to remove the track-hoe using a chain and D-S (CAT) dozer, were unsuccessful. It was felt that the track- hoe was in approximately twenty feet of tailings. The reclamation contractor had damaged the liner at the east side of the tailings impoundment. The area was shown to Mr. Dillie and was told that a contractor was to be on site within
