The <br /> support legs will rest on 4 in x 4 in x 8 ft long wood ties, which will be placed directly on the ground <br /> surface. See the photo of a similar conveyor below. There will be approximately 3,500 lineal feet of <br /> conveyor running from the west processing area, to the south across CR HH.5, then to the west within <br /> Parcel B of the permit area. Approximately 350 wood ties will be required under the conveyor support <br /> legs. <br /> Two washer screens will be located near the start of the conveyor to wash product before it is placed <br /> on the conveyor. These screens will have 12 ft x 19 ft x 1 ft thick concrete pads under them, placed <br /> directly on the ground surface. <br /> On Parcel B where the conveyor turns to the west, a conveyor head unit will be placed to maintain <br /> tension in the conveyor belt.
