monitored by the applicant to determine the effects of the remaining structures on the <br />East Salt Creek alluvial ground water. <br />Narrow bands ofalluvial-colluvial material extend about one mile up Munger Canyon <br />from the cont7uence with East Salt Creek. Monitoring well GW-4, which is 40 feet deep <br />and is located at the lower part of Munger Canyon, was dry in April 1981 during the <br />period of the year of snowmelt and highest precipitation. Test pits TP-1, TP-2 and TP-3, <br />dug to a depth often feet in the Munger Creek alluvium, had no traces of mottling and <br />only a very slight increase in moisture. Additionally, plant species present on the <br />alluvium indicate the absence of natural subirrigation in the Munger Creek alluvium. <br />No wells or springs have been identified within three miles of the mine. Thus, the <br />Munger Canyon mining operation will not effect the quantity or quality of any ground <br />water which is put to beneficial use off site. <br />Grand Valley has committed to the following ground water monitoring program: <br />1) Quarterly monitoring of wells GW-2, GW-3, GW-4, GW-6 and GW-8 for Static <br />Water Level, pH, Temperature, and Specific Conductance. <br />2) Water quality sampling of mine water dischazges as required by NPDES and <br />CDOH permit. <br />3) Monitoring all of non-steep inflows into mine to include source, quantity, <br />duration and quality fpH, Temperature, and Electrical Conductance) <br />4) Monitor quantities of water dischazged form the mine, consumed in the mine and <br />imported for use in the mine. <br />5) Results of the quarterly groundwater monitoring shall be submitted to the <br />Division immediately after data collection and analysis. <br />6) Due to the temporary cessation of the Munger Canyon Mine, the Division <br />approved a revision to sample GW-6 in Munger Canyon. Since GW-6 has been <br />dry since installation, well GW-3 will be substituted and monitored quarterly for <br />Static Water Level, pH, Temperature, and Specific Conductance. <br />E. Water Rights and Replacement <br />Portions of the application relevant to surface and ground water rights in the vicinity of <br />the mini have been submitted to the Office of the State Engineer, Division of Water <br />Resources. The State Engineer's Office has determined that there are no problems with <br />the operation with respect to water rights. <br />3a <br />
