workings directly underlie the Cliffhouse in the Menefee Formation. Water supply wells that <br />aze located within one mile of the permit azea and are probably completed in the Cliffhouse <br />Sandstone include the V. Paulek and G. Paulek wells. <br />The Menefee Formation is afine-grained interbedded sequence of sandstone, siltstone, mudstone, <br />and coal that was deposited on an alluvial plain. Environments ranged from fluvial channel deposits <br />to coal swamps. The Menefee is more than 200 feet thick. NKC mines coal from the top of the <br />Menefee. The Grush well is a water supply well that is located within one mile of the permit area <br />and is probably completed in the Menefee Formation. <br />The Point Lookout Sandstone is afine-grained sequence of sandstone and mudstone that was <br />deposited along a marine shoreline in beach and bar environments. The Point Lookout is more than <br />250 feet thick. It lies more than 200 feet stratigraphically below NKC's coal mine workings. The <br />Point Lookout is not widely used as a source of ground water along the flanks of the San Juan Basin <br />due to low well yields and high dissolved solids content of the water. Water supply wells that aze <br />located within one mile of the permit area and are probably completed in the Point Lookout <br />Sandstone include the Haugen, Funk, Beyer, and Etheridge wells. All water supply wells that are <br />located within one mile of the permit boundary are listed in section 2.04.7 of the permit application <br />and their locations are shown on Maps C-14 and King II-04. <br />The only natural springs located within one mile of the King I and II Mines are the Huntington <br />Springs, located on the north side of Hay Gulch, west of the abandoned La Plata No. 1 Mine azea <br />(File No. C-87-072). This spring, may flow from either the lower Menefee Formation or the Hay <br />Gulch alluvium. A water right to the Huntington Springs was adjudicated and subsequently <br />abandoned, as documented during permitting of the now terminated La Plata No. 1 Mine. The <br />Huntington Springs are beyond the area of influence of the King I and II Mines. <br />Surface Water Hydrology <br />The surface facilities of the King I and II Mines are located in ephemeral drainages that aze tributary <br />to Hay Gulch. The southern portion of the permit azea extends into the Pine Gulch ephemeral <br />drainage. Pine Gulch flows into Hay Gulch approximately 4 miles downstream from the permit area. <br />Hay Gulch is a tributary of the La Plata River and their confluence is located about 8 miles <br />downstream (southwest) from the permit area. <br />There aze no perennial streams within the permit azea. Surface water in the ephemeral drainage <br />basins where mine surface facilities are located is limited to runoff from rainfall and snowmelt <br />events. Runoff from the undisturbed upper parts of drainages is routed around the disturbed azeas <br />through ditches and culverts. With the exception of runoff from main/haul access roads, runofffrom <br />disturbed areas is passed through sediment control ponds which dischazge into Hay Gulch. <br />Hay Gulch does not have a stream channel in the vicinity of the permit azea. Historically, surface <br />flow in Hay Gulch has been diverted into an irrigation ditch on the north side of the Gulch. This <br />ditch carries water for irrigation that has been diverted from the La Plata River. At times the ditch <br />6 <br />
