• be no diminution of water quality or quantity to Hay Gulch from the <br />mine workings or any subsidence related to mining. <br />As there are no surface drainages from the project area connecting to <br />Hay Gulch there is little likelihood of surface water impacts to water <br />quality or quantity from the operation. <br />No water is known to occur in any rock unit above or immediately below <br />the coal seams being mined based on the mining at the National King <br />Mine within or immediately adjacent to the permit boundaries. Again, <br />there is little likelihood of significant impact to quantity or quality of <br />groundwater resources resulting from the King II Mine. Should <br />subsidence related features appear above the mine, water would recharge <br />into the localized groundwater system and not continue off-site, given the <br />dissected nature of the project site topography. <br />The design of the portal facilities and the dip of the strata facilitate <br />drainage of any encountered water in the workings toward the surface. <br />While not anticipated, should water be encountered in amounts that <br />reach the surface, monitoring and control measures will be employed. <br />WATER MOIfITORING <br />. National King Coal, LLC does not anticipate groundwater discharges from <br />any location within the project site. However, groundwater monitoring <br />will be conducted at the baseline alluvial well, °Down-Gradient <br />Monitoring Station" shown on Map King II-004, on a quarterly basis until <br />waived by the Division of Minerals and Geology and shall obtain the <br />following data: <br />a) Depth to water (field data) <br />b) Temperature (field data) <br />c) Conductivity (field data) <br />d) Bicarbonate as CaCoa <br />e) Calcium (dissolved) <br />f) Iron (dissolved) <br />g) Magnesium (dissolved) <br />h) Sodium (dissolved) <br />I) Sulphate <br />j) pH (standard units) <br />k) Total dissolved solids <br />1) Manganese <br />Surface water monitoring will be conducted at discharge monitoring <br />points identified in the NPDES permit.
