<br />Haulage of the finished product will be via the access road (see Exhibit C) which connects <br />with the existing, approved entrance that was previously used for the Great Blue Heron Pit. This <br />haul road is expected to be used throughout the life of the operation. <br />It is possible that truck haulage of the finished product will be eliminated in the future. The <br />applicant is currently investigating the possibility of establishing a rail loading facility on the south <br />side of the Arkansas River just south of the most southerly point of Phase 2. This would be of <br />considerable advantage in that it would reduce truck traffic on Highway 115, reduce the cost of <br />haulage to more distant markets, and improve environmental controls with respect to dust. <br />However, this option would require constructing a conveyor across the river and building a loadout <br />facility adjacent to the railroad. If a railroad loadout is established, then the plant will probably be <br />relocated in the southeastern corner of Phase 2 where it will be more convenient for the conveyor <br />across the river. If that is done, a different arrangement will also be needed for wash water access <br />and wash fine deposition. This plan is not included in the permit at this time, but, if the <br />investigation and negotiations are successful, this facility will be added co the permit via an <br />amendment. It is not known how long this investigation may take or whether approval for <br />bridging the river would be given by the appropriate regulatory agencies. This option is presented <br />here to notify the Division that such a change is a possibility. <br />Nature of Deposit <br />This gravel deposit is very similar to that which was mined at the Great Blue Heron Pit <br />located to the south of this site and now being reclaimed. The gravel is somewhat variable, but <br />averages about 18 to 20 feet in thickness. The gravel is located underneath 4 to 8 feet of soil and <br />overburden. In general, the shallowest overburden is nearest the river, but gravel depth does not <br />necessarily follow that same pattern. <br />A drilling program conducted several years ago showed a general reduction in gravel depth <br />toward the edge of the valley, but it also showed deeper pockets of gravel mired with thinner areas. <br />This pattern probably reflects the shape of the bottom of the valley prior to the deposition of the <br />gravel during the Pleistocene. <br />The drilling program also showed the possible presence of a gravel free pocket of silt and <br />clay on the eastern end of Phase 2. The dimensions of this pocket are not known, but all adjacent <br />holes showed the presence of gravel. Therefore, it cannot be very large. This material, if large <br />enough, may be left in place to form an island in the lake. It might also be removed and used as <br />backfill to increase the lag time in the recharge process. <br />Grisenti Farms Gravel Pit Original Application Exhibit D Page D-8 <br />
