EXHIBIT "D" MINING PLAN Top soil from the affected areas has been stock piled for future revegetation, beginning with the opening of the pit in the 1940's. This top soil consists of dark brown sandy loam and peat. The affected areas include excavations for gravel and sand, the settling ponds and any roads within the site boundaries. In general, the top soil will be stored on the north side of the existing site. The top soil has been removed by loader, dozer and dragline (backhoe), or a combination of such equipment. In the future top soil removal will continue by such methods. The clay-silt fraction which is discharged by the processing plant as spoil, is being stock piled in an old existing pit just south of the active area. This fraction (-200 mesh) will be used for building a low permeability layer in reclamation. Since the processing plant is sited upon a previously disturbed area, minimal additional disturbance will occur. The general method of mining, after the top soil is removed, will be to use a loader and/or dragline to obtain materials for further processing. Since the processing plant is on site, the usual method for moving materials from the excavated area to the processing plant will be to use the loader. Due to the layering of the gravel and sand deposit (See figure ) the mining operation will be staged, depending upon local demand. When gravel is required, it will be removed from the westerly portion of the pit. It is anticipated at this time that five (5) additional acres will be placed into production. The majority of the gravel production for Webster Sand & Gravel Company will be produced at the Jones Pit due to its location and the quality of its gravel. The sand required by the company will be produced at the West Tennessee Pit. The sand deposit at this location is of sufficient depth, quantity and quality to facili- tate mining for many years. The mining of the sand will begin on the easterly portion of the affected area and will not disturb any new areas. The present plan is to excavate sand with a loader from a north-south face. This face will extend from the south boundary of the presently affected area to the north boundary of the presently affected area and will extend from the existing ground surface down to nearly the level of the water table in this area. This open face will slowly move in a westerly direction, thus causing a large open pit with uniform sides and bottom to develop. As the mining progresses to the west, the side slopes will be dressed and reclaimed to prevent erosion and any further disturbance to the environment. The bottom of the pit will be left bare until the extent of the pit is such that a dragline can begin dredging operations again at the easterly portion, thus producing a lake in the area.
