<br />MINING PLAN <br /> <br />EXHIBIT D Icont) <br />The gravel immediately below the topsoil and subsoil can be mined directly. In some areas, small <br />thicknesses of overburden may be encountered. Where necessary, this material will be stockpiled <br />separately from the topsoil and it will be placed on the reclaimed area prior to topsoil placement. <br />This will help in providing additional root zone depth for those areas on the property that do not have <br />good soil depths. During the initial part of the operation it will be necessary to haul the mined <br />material from the site to one of B&B's other operations for processing. The loose nature of the gravel <br />will allow it to be mined with dozers and front end loaders. Front end loaders will ultimately <br />transport the material to the crusher in the facilities area on site. <br />Step 5 -Although the operation will be fully dug out of the existing ground and no disturbed area <br />drainage can leave the site, a sediment sump will be constructed in the pit area to handle process <br />water and the runoff from the 100 year - 24 hour event, thus no NPDES permit vv~ll be required <br />during operation in the pit. <br />Step 6 -Once enough room has been excavated at the bottom of the pit, additional portable <br />processing facilities will be brought in which will be used on site for the remaining life of the mine. <br />The processing equipment and facilities are described in detail later in this section. <br />Step 7 -Mining will progress in Stage A at a rate of 50,000 tons per year for a period of 10 years. <br />This production level will mine approximately 13-16 acres during the 10 year period. <br />Step 8 -After the initial 10 year period, Eagle County will be given the right to close the pit or allow <br />the pit to proceed into full-scale production. If full production is chosen, the remaining area of Stage <br />A will be mined out at a rate of 100,000 tons per year in the first year and climbing to 300,000 tons <br />pet year in the sixth year. Full production of 350,000 tons per year is not reached until the 20th year <br />after the full production operation is approved. <br />15 <br />
