Due to the uncertainty of the location of the potential water call, it is not known which headgate(s) would be shut <br />off. It is highly unlikely that this situation would ever occw. <br />L) A map prepared accordine to the standards of 2.10 showine: <br />f~ The locations of water sup~v intakes. ditches, reservoirs, and wells within a one mile <br />minimum radius of the affected area. current users of surface water flowine into, out of, and within a hydrologic <br />area defined by the Division, and those surface waters which will receive discharges from affected aeeas in the <br />proposedpermit area and adjacent area: , <br />(bl Elevations and locations of monitorine stations used to gather data for water quality and <br />~ uanti <br />fc) Location and extent of sub-swface water. i~f encountered within the proposed permit or <br />adiacent areas. including but not limited to areal and vertical distribution of aquifers and estimate of seasonal <br />variations of aquifer characteristics on cross sections and contow maps as appropriate. <br />(d) Location of surface water bodies such as streams. lakes. ponds, springs. constructed or <br />natwal drains. and irrigation ditches within the proposed permit and adjacent areas: <br />~) Location and dimension of existine aeeas of spbil, waste, and non-coal waste disposah dams, <br />embanlanents, other impoundments. and water treatment and air pollution conVOl facilities within the proposed permit <br />area; <br />(f) Location, and depth, if available. of gas and oil wells within the proposed pernrit azea and <br />water wells in the Hermit area and adiacent area; and <br />fg) Elevation and location of test borings and core samplings. <br />RESPONSE <br />Identification of surface and ground water featwes which exist prior to underground mining, as well as water <br />monitoring stations used for baseline data collection, are shown on Map 13, Twentymile Park Hydrology, and Map <br />14, Five-Yeaz Mine Plan Baseline Hydrology. The facilities to be used for water handling and treatment, as well as <br />information on impacts of mining on water resowces, aze shown on Map 16, Water Control and subsidence <br />Monitoring Plans and Map 24, Surface Facilities. <br />Sub-surface water featwes, including extent and characteristics of aquifers, identification of monitor wells, and <br />elevation of water table and piezometric surface of aquifers are shown on Map 13, Twentymile Pazk Hydrology, and <br />Map 14, Five-Year Mine Plan Baseline Hydrology. In addition, locations of existing stream channels, impoundments, <br />irrigation ditches, and drains are shown on Map 15, Alluvial Valley Floors and Water Rights. <br />Areas of spoil, waste, non-coal waste disposal, water handling and treatment facilities, embartkrnents, and <br />impoundments are shown on Map 24, Surface Facilities, and Map 26, Fish Creek Borehole/Shaft Area Facilities <br />and Access Road. Elevations and locations of test borings and core samplings are shown on Map 12, Sample <br />Locations. <br />One oil and gas well exists within the pemtit boundary for the Southwest Mining District. The well was drilled <br />during 1975, and originally was completed as an oil well. However, the yield was insufficient and the well was <br />converted to a gas well. The well is approximately 7,500 feet in depth and its location is shown on Map 23. <br />Twentymile Coal Company acquired ownership of the well in 1993. The well was plugged by placing a cement <br />• plug in the well. <br />PR06-07 2.04-40 11/07/06 <br />
