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. Suooort Facilities Coal waste, stored temporarily, has been pushed over the back of the concrete storage bunkers. This material should be picked up and hauled to the lower refuse pile. MCC has begun to use the hydraulic storage parts building. The former storage location is almost empty with the exception of a few heavier parts. MCC is awaiting the delivery of a hoist for the building before the parts are moved to the new storage location. Once this occurs, contaminated soils in the old location should be removed and disposed of properly. MCC should consider extending the berm around the coal storage at the three stacktubes further to the southwest to ensure that any surface runoff from the coal pile would flow through the silt fence. MCC has experienced some additional water line breaks. As part of the water line improvement project, approved as MR#114, the surface water line will be extended to the office and shop. This additional line can be included with the as-builts and submitted as a minor revision. Ms. Welt informed me that the material storage bench, portal bench and shop/warehouse area are being considered to be surfaced with RCC. A revision should be submitted for this project as well. Ms. Welt informed me that with an increase in their work force additional shower facilities are needed. MCC has purchased trailers for these facilities. A revision should be provided indicating the location of the trailers and any bond estimate increase. Topsoil Grass is beginning to grow on the topsoil pile and pad adjacent to the Lone Pine Gulch substation. MCC is planning to seed the disturbances and topsoil piles located in Lone Pine Gulch before the end of April, weather permitting. Grass is also beginning to grow at the main topsoil stockpile on the mine site. Slides and Damacxe There has been a rotational slump under the main access/haul road at the keystone wall. The wall is still intact and the road is still passable using one lane. Instability has occurred in this area in previous years. MCC has proposed a repair plan which includes a series of french drains, a perforated culvert, and a buttress. Preliminary approval was given to MCC to begin the construction. Final approval is contingent upon the Division's review of the design and stability analysis of the buttress.
