2.3-3 <br />2.3.2 Ground Water Inflow Durinff Mining <br />• It is not anticipated that water will be encountered during the <br />mining operation. Numerous drillholes were drilled to an average <br />depth of 50 feet Delow the Cameo Coal Seam with virtually no water <br />inflow realized and practically no retention capability. The <br />results of geophysical log interpretations of the most recent <br />boreholes east of the Munger Canyon Mine entries confirm the absence <br />of watec~ in the strata. Drillhole 7-21-3, located in the northeast <br />quarter of Section 21 just north of the permit area, was dry to <br />about 210 feet below the Cameo seam. Drillhole 7-15-3-3, located <br />northeast of the permit area, was drilled 38 feet below the Cameo <br />and was also dry. <br />Due to the geologic limitations of the area, the Munger Canyon <br />project for this permit term (5 years), will not extend to a point <br />where water will require pumping or extensive monitoring, see <br />Figures 4.2-4 and 4.4-1. At a later date, it may become necessary <br />to begin detailed groundwater monitoring. All applicable statutes <br />and regulations will be adhered to regarding water discharges, <br />including an NPDSS permit. Monitoring methods, frequency and <br />parameters to be analyzed are shown on Tables 2.5-1 and 2.5-2. <br />2.3.3 Water Requirements DurinK Mining and Reclamation <br />Water is required for the cooling of motors on mining equipment, the <br />suppression of respirable coal dust, and the control of fugitive <br />dust along the haul road and et the crusher. The maximum water <br />• volume necessary for the underground operation is approximately 20 <br />gallons per minute or 16,800 gallons per day or 3,800,000 gallons <br />per year. Water requirements for fugitive dust control are <br />approximately 8,000 gallons per day or 1,200,000 gallons per year. <br />There will be periods when no water will be required; thereby, <br />reducing this requirement by an indeterminate volume. <br />2.3.3.1 Water RisFhts <br />All water used in the mining and pollution control operations will <br />be obtained from the Colorado River near Loma. GVC has s first and <br />prior right to 10 cfs of water from the Mack Pumping Pipeline as set <br />forth in C.A. No. 13368, Mesa County District Court by decree, <br />April 13, 1972, and as modified May 29, 1974, see Appendix C. <br />C~ <br />RN-oL <br />M11 1: 30%?3 <br />
