Banks and Gesso, LLC <br />reclamation. The aggregate plant will be moved on site as soon as all appropriate <br />permits are obtained. <br />Mining will begin in the southeast portion of Mine Area 1 and proceed west then north, <br />and then around the plants located in the center of the mine area. The processing <br />plants will then be relocated to the southeastern corner of Mine Area 1, so that the area <br />beneath them can be mined. <br />Sand and gravel excavation in Mine Area 1 will occur at 0.5:1 slopes. Excavated <br />materials will be transported to the processing plant via off-road haul trucks or <br />conveyors. Stripping of other areas will allow for excavation of dewatering ditches, <br />sediment and sump areas and setting the pumping systems. Underground power lines <br />will be constructed to provide power for the electric dewatering pumps and plant <br />equipment. As soon as mining limits have been reached, reclamation of the pit edges <br />will begin. This will allow for concurrent backfilling of the pit perimeter with previously <br />stripped overburden. <br />Phase 2 Mining Sequence <br />Mining will occur from west to east. Sand and gravel excavation will occur in Mine Area <br />2 at approximate 5:1 slopes. The pit will be mined at the proposed reclamation slopes, <br />eliminating the need for backfilling during reclamation. Excavated materials from Phase <br />2 areas will be transported to the processing plant via conveyors. <br />Description of Overburden. Deposit and Underlyino Stratum <br />It was assumed that the overburden thickness at the Heit property was similar to <br />surrounding sites, approximately 2 to 3 ft. Based on the site's previous use as an <br />agricultural crops farm, the soils are believed to be suitable for reclamation efforts. <br />Based on the exploratory boreholes, an average of approximately 23 ft of sand and <br />gravel is situated below the topsoil and overburden in Mine Area 1. In Mine Area 2, <br />there is an average of approximately 13 ft of sand and gravel. <br />Heit Sand and Gravel Mine 02044 <br />SW Meadow, LLC February 2003 <br />8 <br />
