MINING PLAN AND TIMETABLE EXHIBIT D(CONT) Water Resources . In general, mining will commence in Phases 1, 2 & 4 on the south end and work north as shown by the arrows on the MINING PLAN MAP. In Phase 3, mining will start on the north and work south. The maximum length and cut/fill volumes of the working face and backfill on the side wings in each stage are shown on the MINING PLAN MAP. The mining setbacks will vary from the permit boundary and structures as allowed by each agreement for said structures and/or the Geotechnical Stability Analysis . This analysis shows that using the 25 feet setback from the slurry wall is adequate to meet the factors of safety in the DRMS Rules and Regulations, (see D&A Slope Stability Factor of Safety Results Summary Table on Page 4 of their report) . The proposed setbacks are shown in the Setback Table on EXHIBIT C - STRUCTURES M� MAP The material will be mined using loaders and excavators (track hoes) to remove material from the face . The material will then be delivered to the Plant for processing using haul trucks or a conveyor system. No blasting will take place at this mine. Reclamation will run concurrent with mining to control the amount of disturbed area in the mine at any-one-time . Reclamation begins in an area once the section is fully mined, and large enough for efficient reclamation (backfilling, compacting, sloping, soiling, etc. ) that will not have to be re-disturbed. This pit will be operated year-around by L.G. Everist, Inc. , weather permitting. There may be periods when the demands for material are slow and no mining will take place, creating an in- termittent operation situation . Areas not included in the bonded area will remain in agricultural production. a-re m intenanee is i�etaj-ne,l ley t1,e , ,nd, .. Please refer to the MINING TIMETABLE for the estimated acreage of each area associated with the mining part of this operation. Mining equipment may include but is not limited to, front-end loaders, scrapers, excavators, a drag line, dozers, off-road haul trucks, dump trucks and a water truck. Most of the water used on site will be for dust control used on haul roads or with sand and gravel processing. Please refer to EXHIBIT G - WATER for the discussion of how water will be used at the site, the estimated yearly needs, and the source (s) of said water. Prior to mining into the groundwater table, the applicant/operator/permittee will obtain a Substitute Water Supply Plan approval from the Division of Water Resources . L.G.
