r .i King I & II Complete Oversight Inspection: Cohrado Division of Reclamation, Mining and Safety (DBMS) Permit ID # C-1981-035 Wednesd"q October 6, 2010 9:15 - 2:45 Participants: Tom Kaldenbach, DBMS Tom Bird, Grande Cache Coal Co. (GCC) Jim Jarvis, GCC Christine Belka„ Office of Surface Mining (OSM), Badge ID #182 Elizabeth Shaeffer, OSM, Badge ID 377 Weather conditions: clear, cool (50's / 60's), cloudy, recent light rain This was a complete oversight inspection of the King I and II mine sites. King I is being reclaimed, King II is operational. We began the inspection at King II. Signs and Markers (King II) The mine ID sip was intact and contained all of the necessary information. The King II disturbed area is marked with Permit Boundary markers. The disturbed area is within the permit area, and the boundary markers clearly identify areas approved for disturbance. One area on the north edge of the facilities by the coal stockpile (near the large topsoil stockpile) did not have boundary markers. Mr. Kaldenbach informed Mr. Bird and Mr. Jarvis of the need to post two additional boundary markers in the area. Mr. Kaldenbach was to follow-up on this issue the following day. Soil stockpiles were appropriately marked. Facilities / Operations The new office area has been cleared and prepped for construction. GCC has the building in storage, but it may be cost prohibitive to reassemble the structure on site. Mobile home options are being explored. The material storage yard is orderly. The main travel-way portal and vent portal were open and the vent fan was operating at the time of inspection. The conveyor portal was also open and operating. Topsoil The main topsoil pile appears stable, but vegetation is rather sparse and consists mostly of weeds. The late spring and low rainfall have combined to make a bad year for vegetation in the area. The stockpile was obviously seeded, as flax was present. The smaller southern topsoil stockpile near the pond exhibited a better vegetative cover and was also stable. Diversions / Sediment Control The western rock-lined clear water diversion was in good condition. The Cochrane Canyon east clear water diversion was also in good condition. The Pond had some wet areas, but was not impounding water. The north culvert was partially filled with sediment and needs to be cleaned out. Mr. Jarvis indicated that he will flush out the culvert and attempt to create a steeper gradient into the pond to prevent the settling of solids in the culvert. The Pond outlet discharge culverts were also filling with sediment and need to be cleaned out.
