At the time of this inspection, the entire haulJaccess road from the intersection to the coal stockpile appeared to be coated with coal fines. Coal dust was evident in the roadside ditch and on cut and fill slopes and vegetation adjacent to the road. Apparently, the coal spillage is a result of overloading of the haulage trucks. The problem had not been noted at Red Canyon prior to the February inspection. Continued accumulation of coal in and adjacent to the haul road and ditches will potentially cause disturbance to the hydrologic balance outside the permit area. 4.05 Hydrologic Balance Two problems were noted in the vicinity of the coal stockpile. Coal had been spilled over the berm south of the pile near the outlet of the recently installed culvert. The coal must be removed and the berm reestablished. The inlet of the culvert near the turnoff to the refuse disposal had been repaired, but the culvert had become clogged again. The diversion ditch, drainage ditches and remaining culverts and the sediment pond appeared functional. Certain aspects of the mining plan were discussed with the operator, including the possibility of an experimental full extraction panel, limitations on the underground operations until additional hydrologic monitoring systems are installed and data collected the need for additional piezometers below the waste pile and the suitability of the proposed subsidence monitoring plan. These issues will be addressed in a separate letter within fine next two weeks.
