Page 9 <br />(south) boundary of the permit azea, to two miles to the north of the downstream (north) permit <br />boundary, is identified as a specified area. <br />As there is an indication of impact to alluvial waters in the alluvial valley floor that is adjacent <br />to, and downstream for a distance, east of Trout Creek, the current (flood plain) alluvial valley <br />floor of Trout Creek, from the upstream (north) permit boundary, and for a distance of two miles <br />downstream of the upstream (north) permit boundary, is designated as a specified area. <br />Use and Classification of Ground Water <br />The two bedrock wells, WP 94607 and WP 209186, within a mile of the permit area, and the <br />three bedrock wells, WPs 90792, 240793, 237610, within two and a half miles of the permit azea, <br />are used for domestic uses. Thus the groundwater in the Trout Creek Sandstone specified area <br />might be designated for Domestic Use -Quality. <br />Other than unregistered monitoring wells, there are no known recorded alluvial wells in the <br />current alluvial valley floor that are within two and a half miles, and down gradient of the permit <br />area. Thus there is no alluvial groundwater well that would lead to classification of alluvial <br />groundwater within the specified area. <br />Baseline informations' is available in the PAP for thirteen of the nineteen constituents of Table 1 <br />(page 22) of C WQCCR 41. A classification of domestic use is not precluded. Alluvial <br />groundwater is not used, and historically has not been used, for domestic use within the specified <br />area. There aze alluvial wells upstream from the affected area that aze registered for domestic <br />use; but downstream, as far as two and a half miles, domestic use wells have been set into <br />bedrock. TDS levels, even in the spoil groundwater of 4,000 mg/1 range, do not discount a <br />classification of domestic use. The alluvial groundwater appeazs to meet the criteria for a <br />classification of Domestic Use -Quality. <br />The spoil springs discharge, through the sedimentation ponds, into Trout Creek. Consideration of <br />this spoil spring water and classification, asurface water (stream standards) review, is not within <br />the scope or purpose of this opinion. <br />54 PAP page 4.6-144 <br />
