• Exhibit Page 14 • <br />SURFACE WATER MANAGEMENT: <br />Temporary structures will be constructed on the floor of the pit and in stripped areas to <br />divert water from active mining areas and to reclamation and long-term stockpile areas, <br />or to a discharge point. During the mining of the lower level, a swale about one foot <br />deep and with its base about fifteen feet back from the toe of the working face will be <br />established to reduce water at the face of the excavation. Sumps (as well as sediment <br />and wash basins and ditches) will be dug during the mining of the upper level, to allow <br />better drainage, both surface and subsurface. The drainage from the active areas will <br />be controlled and treated as required by water quality regulations and permits to <br />ensure that no sediment from the pit is discharged into the Dolores River. <br />The pit floor is below the surrounding land and there will be no discharge under normal <br />conditions from the pit areas during mining, except by drainage through the preexisting <br />pipe or by pumping of water through surface-laid pipes to an ouffall in the river. The <br />Dolores is a warm-water fishery: discharge temperature regulation is not required. <br />During the winter months, gravity flow of water may be halted to protect the pipe from <br />freezing. Water collecting and and flowing through the pit would then be allowed to rise <br />to a stable level and freeze, and then will be discharged after spring melt. When mining <br />the lower level, no dewatering will be done during the winter months. A spillway will be <br />established and maintained through the berms (stockpiles) around the pit, in case of <br />flooding of the Dolores River, blockage of the pipe, or other events which might cause a <br />surface discharge, to minimize erosion, sedimentation, and traffic problems. Stockpile <br />areas will be designed with perimeter ditches/swales and berms with silt fence, straw <br />bales, or rock check dams to prevent sediment in any runoff to the creek. <br />ASSUMPTIONS USED IN MINING PLAN: <br />The mining plan is based on several key assumptions, stated herein for evaluation. <br />These assumptions are not intended to imply or claim that certain actions will be done. <br />1. Annual demand for sand and gravel from this pit will be approximately 140,000 tons. <br />Demand, and therefore production, may vary significantly from year to year, and <br />therefore acreages affected during a given year may be either larger or smaller than <br />included in this plan, thus impacting on stockpile size and other matter. <br />2. Activities on the site (stripping, mining, stockpiling, etc.) will be done primarily during <br />the later summer/early fall period, from mid-August to mid-November. <br />3. The upper 2 feet is considered usable topsoil but includes approximately 50% <br />oversized (cobbles, etc.) that can be screened out to improve soil and provide <br />additional rock, but need not be done for material used only for backfilling. <br />4. Water table in the pit area fluctuates seasonally and from year to year. <br />5. Wash water for processing will be recycled and will be mixed with storm water and <br />dewatering flows for discharge. <br />6. A plant will be on-site during the period of stripping and mining, so that large <br />temporary stockpiles of soil and raw material will be quickly processed and remain in <br />existence for very brief periods. <br />~ This is described in the surface water management plan, which provides detailed information. <br />Four States Aggregates, LLC 30 DEC 2000 <br />Application for Permit: Line Camp Pit FSA-LCP-D1-001 <br />
