The Huntington Springs is located on the north side of Hay Gulch west of <br />the La Plata No. 1 Mine area (File No. C-87-072). This spring, which <br />may issue front either the lower Menefee Forntation or the Hay Gulch <br />alluvium, has been adjudicated for a water right. La Plata Coal <br />Corporation demonstrated during permitting of the La Plata No. I Mine that <br />this water right has been abandoned; therefore, no fiirther investigations or <br />monitoring are being required. <br />Two water supply wells are located within or near the pemtit area: one at <br />the King Coal Mine and one at the La Plata No. 1 Mine. A third water <br />well, located in an upslope terrace deposit, has been capped and abandoned. <br />Although no completion data have been submitted, it appears that the <br />abandoned well was completed in the underlying Point Lookout Sandstone. <br />The National King Coal water supply well is completed in the Hay Gulch <br />alluvial aquifer just west of the facilities area. The La Plata No. I Mine <br />well, which has been reported to be in existence since about 1905, is <br />located near the facilities area ctf that mine. This well, for which a water <br />right has been filed is probably completed in the Point Lookout Sandstone. <br />The February 4, 1982 Findings Document imposed a stipulation pertaining <br />to covering the Hay Gulch alluvium well and using this well for monitoring <br />purposes. <br />National King Coal covered the well and perfontted the necessary <br />monitoring throughout the first permit term. Because National King Coal <br />will continue to use this monitoring well as a water supply well for [he <br />mine and because this well provides valuable information about the alluvial <br />water quality, the Division determined monitoring should continue. Rather <br />than continuing with this stipulation, National King Coal committed to <br />performing the necessary water monitoring. Table 1 lists the water quantity <br />and quality patanteters to be monitored quarterly on a rnonday morning <br />after the well has set idle for the weekend. These results will be submitted <br />to the Division quarterly. <br />Table 1 <br />Depth-To-Water (Ft.)

In 1986, however, mining began <br />to encounter ground water resulting in this water being pmnped to the <br />surface and discharged to the west sediment pond.
