F. Ground and Surface Water Monitoring <br />The applicant will conduct monitoring of ground water in a manner approved by <br />the Division. The ground water monitoring plan is described below. (4.05.13(1)). <br />Ground water is monitored in two alluvial wells in Hay Gulch downgradient from <br />the King I Mine and downgradient from the King II Mine. Section 2.04.7 and <br />2.05.6 of the permit application require both alluvial welts to be monitored for the <br />following parameters on a quarterly basis: <br />Table 1 <br />Depth-To-Water (ft.) Magnesium <br />pH Sulfate <br />Temperature (°C) Iron <br />Conductivity Sodium <br />Total Dissolved Solids Bicazbonate <br />Calcium <br />Historical observations indicate the producing coal seam and its overburden have <br />been essentially dry at the King I Mine. In 1986, however, mining encountered <br />ground water resulting in this water being pumped to the surface and discharged <br />to the west sediment pond. It is hypothesized mining dewatered an overlying <br />perched aquifer. It is possible, however, that some inflow from the Pine Gulch <br />drainage may have occurred. <br />2. The applicant will monitor surface water in a manner approved by the Division. <br />The monitoring plan was submitted under 2.05.6(3)(b)(iv)and isdescribed below. <br />(4.05.13(2)). <br />Surface water monitoring is limited to NPDES discharges, as no surface streams <br />with regular flows occur in the permit area. Required monitoring of the irrigation <br />water from the La Plata River ended in the fall of 1998. <br />G. Transfer of Wells <br />At the conclusion of mining, the two wells used in the operation will be transferred <br />back to the owners at the written request of the surface owners (4.05.14). <br />H. Discharge of Water into an Underground Mine <br />No surface water will be dischazged into the underground mine workings (4.05.15). <br />16 <br />
