An alluvial ground-water aquifer has been identified along East Salt <br />Creek. The applicant submitted alluvium baseline ground-water <br />monitoring data for three calendar quarters of 1981, and has <br />committed to gathering an additional year of quarterly water quality <br />data and monthly water levels beginning in the third quarter of <br />1985. This data will be used by the Colorado MLRD to determine <br />whether the mining activities are having any unanticipated effect on <br />the East Salt Creek alluvial ground water. The applicant has also <br />committed to the installation of an additional ground-water <br />monitoring well to be located down gradient of the proposed central <br />facilities area slurry pond. Three existing water monitoring wells <br />will be maintained throughout the life-of-mine in order to assess <br />any other unanticipated effects of other structures associated with <br />the central facilities area on the East Salt Creek alluvium. <br />East Salt Creek has been determined to be an alluvial valley floor <br />(AVF). Irrigated cropland and grazing areas exist here. The <br />central facilities area will affect approximately 43.4 acres of the <br />East Salt Creek AVF. The Colorado MLRD has determined that the <br />proposed surface facilities disturbance would result in a 0.6 <br />percent loss of production during mining and has made the finding <br />that the proposed surface facilities would affect a small area of <br />the alluvial valley floor which provides negligible support for the <br />production of the farming unit. <br />
