ACMA has <br />contracted with appropriate consultants to locate and permit this well. <br />On-site water distribution will be by means of underground metal or plastic pipe of appropriate size <br />for the service intended. <br />6.3.3(1)(1) Ground Water, Surface Water Encountered/Disturbed; Sediment Containment <br />System; Storm Water Runoff Control; Groundwater Points of Compliance <br />Avalanche Creek Marble & Alabaster does not anticipate encountering or disturbing ground water <br />in its surface operations or excavations or grading therefore. <br />Avalanche Creek Marble ~ Alabaster does not anticipate encountering or disturbing significant <br />amounts of groundwater in its underground operations. ACMA does not anticipate encountering <br />groundwater in quantities requiring dischazge above the water table. Because of the nature of the <br />geology of the Sopris syncline, on which the White Banks claims occupy the up-dip end, or nose, <br />ACMA does not anticipate encountering or disturbing groundwater in quantities requiring discharge <br />below the water table. <br />There aze no permanent or intermittent streams within the affected area. There are no ponds, lakes, <br />or ditches within the permit area. ACMA therefore does not anticipate encountering or disturbing <br />surface water in its surface or underground operations. <br />Because of the extremely small size of the disturbed area (approximately 2.7 acres) an extensive and <br />formal sediment containment system, such as ditches, culverts, and sediment ponds, which could <br />disturb an azea equally as great or more, is not contemplated. Sediment, which will be produced <br />exclusively as a result of storm water rvnoffand snowmelt, will be settled by grading the mine bench <br />to create a catch basin against the portal face cut to receive runoff from the portal face cut and bench. <br />Water caught in this basin will evaporate or percolate through the bench material; excess water, if <br />any, will run off the bench via the ditch along the west side which conducts drainage from the dry <br />gulch at the west edge of the permit area through the site; this ditch currently exists and will be <br />modified only slightly. Drainage from the mine bench outslope will be directed through the mine yard <br />by grading to settle in gravel via sheet flow. Runoff from the lower mine road, the west ditch, and <br />excess from the mine yard, if any, will be directed into the existing FDR 310 ditch, which then drains <br />across FDR 310 just west of the permit boundary by means of a low dip crossing, into the meadow <br />on the southwest side of the road. On the lower, southwest side of FDR 310 the natural drainage is <br />incoherent. Snowmelt drainage when the ground is frozen simply meanders through the trees and <br />meadow where snow cover allows, even under snow in some cases, with no consistent identifiable <br />channel (there is a newly cutting channel further to the southwest, along and just outside of the <br />southwest permit area boundary, which takes drainage from the large Red Canyon waterbaz on FDR <br /> <br />
