Phase Overview <br />Initially, a portable screen and crusher will be used to process material within the existing <br />permit area Phase [located east of the Plant Site area. Lafarge will begin mining by <br />excavating the initial settling basin and clean water pond for the project. The first tailings <br />pond will eventually encompass all of Phase I Cell 2. Phase I Cell 1 will be utilized as a <br />clean water pond throughout the length of the project. Material from Phase II and <br />following phases will be transported via conveyor system to the processing plant at the <br />Plan[ Area. Waste from Phase II will initially be deposited in Phase I tailings pond (Phase <br />I Ce112). <br />Following the mining of Phase I Cells 1 and 2, Lafazge will install a stationary fixed plant <br />and operate the stationary plant simultaneously with the portable equipment until maximum <br />efficiency is achieved. At this time, portable equipment will be removed from the Site; <br />however, during times of increased production Lafazge may reinstall portable equipment on <br />a temporary basis. <br />Lafarge will continue mining in sequential phase order. However, based upon geologic <br />conditions encountered, Lafazge may need to alternate phases to maximize gravel <br />extraction. Mine cell mining order may vary within each phase. <br />In order to gain an understanding of the extent of the mining operation, it is helpful to <br />know the acres disturbed by different aspects of the mine. W e have selected a point in time <br />where the mining disturbance could be at its maximum. This occurs during the mining of <br />Phase V Cell 1. The mining face is in the east/west direction will be at its greatest length. <br />The following acres of disturbance apply at this time: <br />A. Stripped overburden and topsoil in anticipation of mining 30 acres <br />B. Active mining area, possible plant site 30 acres <br />C. Topsoil and overburden stockpiles 10 acres <br />D. De-watering trench 10 acres <br />E. Mining face, 2000 fr 10 acres <br />F. Roads 5 acres <br />G. Side slope undergoing backfilling and grading, 600 ft 10 acres <br />H. Side slope being seeded, 600 ft 10 acres <br />I. Finalization of Compacted Liner Phase IV 25 acres <br />J. Top of slope 5 acres <br />Total disturbance: 145 acres <br />Equipment <br />The following equipment and facilities will be utilized in this operation: <br />Conveyors (50) Secondary Crushers Dozers (3) Graders (2) <br />Loaders (3) Generator Set Scrapers (IS) Back Hoe (3) <br />Compactors (3) Portable Screen Office Trailer (1) Portable Toilets (2) <br />Primary Crusher (1) Wash Deck Portable Crushers Scale House <br />F[ Lupton Pit <br />DMG 112 Permit <br />Page !5 aj81 <br />
