Colowyo C-1981-019 19 December 2007 Pg 4/6 Hydrologic Balance (cont.): - Sump 1 contained water approximately two feet below the top at the time of the inspection and was not discharging. The sump was covered with snow but it appeared to be stable at the time of the inspection. - Sump 2 contained water approximately two feet below the top at the time of the inspection and was not discharging. The sump was covered with snow but it appeared to be stable at the time of the inspection. - Sump 3 contained water approximately two feet below the top at the time of the inspection and was not discharging. The sump was covered with snow but it appeared to be stable at the time of the inspection. - Sump 4 contained water approximately two feet below the top at the time of the inspection and was not discharging. The sump was covered with snow but it appeared to be stable at the time of the inspection. - Sump 5 was covered with snow at the time of the inspection so it was not clear how much water it contained. The sump was not discharging at the time of the inspection. The sump was covered with snow but it appeared to be stable at the time of the inspection. - The West Taylor Pond was inaccessible at the time of the inspection due to snow. Backfilling and Grading: - The reclamation and backfilling operations in the East Pit were inaccessible at the time of the inspection due to snow. The 101 dragline was sitting on the East Pit highwall at the time of the inspection but it was not operating. It does not appear that it has moved a great deal since my last inspection in October. - The top of the West Pit overburden stockpile still needs to be removed to the new approved elevation as permitted in Technical Revision 63, Support Facilities: - The facilities area was in good condition at the time of the inspection. No problems were noted with the area. - The Gossard Loadout appeared to be stable and in good condition at the time of the inspection. No fugitive dust coming from the coal stockpiles or stacker tube at the time of the inspection. Topsoil: - The operator moved the topsoil stockpile at the south edge of the West Pit to allow for pit advancement and work on the South Taylor Pit. This topsoil was moved to the west edge of the East Pit. The operator was working on sloping the pile so it can be seeded. - The operator, through the contractor Bower Brothers, has finished removing topsoil in the Taylor Creek drainage in what appeared to be the area of the East Taylor Fill. The topsoil was stockpiled in a new pile just south of the West Pit (west of the Section 16 Pit) and to the pile above the East Pit highwall. The operation has now moved to the area just south of the open Section 16 Pit, in advance of the scheduled South Taylor mining. This topsoil is being hauled to the stockpile at the edge of the East Pit highwall. One concern with removing topsoil at this point in the year is that the conditions will damage either the chemical or physical properties of the topsoil (or both). Although it was cold and the topsoil looked good at this point (it was not wet and muddy), the contractor was dumping the topsoil and pushing it with a dozer.
