r (Page 2. To Mrs. Carol Russell from Sunland Mining Corporation) without ditch D-7's existance. Furthermore, were the road per-se be unable to completely divert undisturbed runoff away from our disturbed area, the resultant failure would merely add to the inflow of the settling pond. The settling pond has adequate excess capacity. This was demonstrated earlier this year, when a 2" rainfall event failed to fill the pond even to the point of dewatering overflow. Since the hydrologic protection need only function to the 10 year event, it certainly seems likely that additional inflow could be legally accommodated. We are an underground mining operation. The surface excavation equipment which we own is limited to loaders and a backhoe. Ditch D-7, as it exists now, required a considerable amount of work. Blasting was required in several sections so we could excavate the ditch. This necessitated the trans- portation of several ancillary pieces of construction equip- ment including an air compressor and drill. Although it is true that the road was nearly free of snow at the time of your last inspection, it was still quite muddy. Presently, there is about 10 to 12 inches of snow on the road. Because of the amount of work necessary to construct (or enlarge) ditch D-7 under the confines of physical conditions, a "window" of. at least two weeks of good weather with a dry and snow-free roadbed would be required to undertake ditch construction. There is no way such a construction job could be completed prior to February 1. At the time of spring thaw, we will (with your consent), walk the road and repair (by hand - with shovels) any portion of the outside road-edge berm breached by runoff so the undisturbed runoff remains on the road surface and is precluded from reaching the settling pond.
