Colowyo C-1981-019 20 January 2009 Pg 3/4 Hydrologic Balance (cont.): - Sump 4 was dry at the time of the inspection. The sump was stable at the time of the inspection. - Sump 5 contained water to the top of the sump but did not appear to be discharging at the time of the inspection. The sump appeared to be stable at the time of the inspection. Backfilling and Grading: - Colowyo has committed to provide two reclamation schedules for the East Pit closure. The first plan is a short term plan that will encompass the area around the Prospect ditch, including the sump area that is part of the ditch which is not yet to final grade. This short term plan, in the form of a Technical Revision, was received by the Division on 24 December 2008. The second plan is a long term plan that will provide a comprehensive reclamation schedule for the remaining East Pit, including the closure of the final pit. This long term plan is due to the Division in the first quarter of 2009. - Colowyo was hauling overburden from the A-Seam to the final pit area of the East Pit at the time of the inspection. The material was being hauled up a pit ramp on the East edge of the West pit and was being dumped on the west edge of the East Pit. - The operator was performing backfilling operations in the Section 4 area of the West Pit at the time of the inspection. The operator was loading spoil from a temporary pile with a loader and dumping it along the east edge of the pit just above the East Taylor Pond. This material was then being pushed into the pit by a DI dozer. A very small portion of the area has reached final contour. No other backfilling operations were being performed in the West Pit. Colowyo is required to submit a Technical Revision detailing the reclamation of the West Pit. This deadline was 23 January 2009, which has passed. Colowyo must submit this revision immediately. Topsoil: - No topsoil was being stripped at the time of the inspection. Ryan indicated that all stripping operations have ceased for the winter and will start up again probably in late spring. - The large topsoil pile just north and east of the C-C' underdrain of the East Taylor fill has been dressed and sloped by Bower Brothers. They have also cut a perimeter ditch around the pile to help protect the resource. The pile still needs to be seeded and Ryan indicated that they may still seed it this winter. General Mine Plan Compliance: - The 101 dragline is on the East Pit highwall where it was waiting to performing reclamation (although it has not been running for several months). - The 102 dragline was working on the east side of the West Pit removing B-Seam overburden. - The 103 dragline was working in the west side of the West Pit removing B-Seam overburden. - The 114 shovel operation was working on removing A-Seam overburden in the West Pit. - The 115 excavator was working on removing overburden in the South Taylor box-cut area. This material was being dumped in the C-C' drain of the East Taylor fill.
