<br />Exhibit G -Water Resources <br />Surface Water <br />Mining is expected to have minimal impact on the prevailing hydrologic <br />balance. The site lies on terrace formed by the historic occupation of the <br />Uncompahgre River. However, the area to be mined now lies several hundred <br />west of the river at its closest approach. No mining will occur in the <br />active stream channel. <br />The surface slope of the permit area is minimal, averaging less than <br />one percent. Runoff fran the affected area is limited to periods of <br />snowmelt and surtmer storms and occurs as overland flow. However, runoff <br />velocity is very low due to the gentle surface slope. Most of the storm <br />water occurring on site will be confined within the permit area and drain <br />to the pond as described below in a seperate section. <br />Irrigation Ditches <br />Earthen irrigation ditches occur on site as illustrated on the Exhibit <br />C map. These ditches terminate on site and will simply be rerouted or <br />eliminated as necessary in order to accomiadate the mining operation. <br />Ground Water <br />Ground water is encountered at a depth of about three to four feet <br />below the ground surface, but varies same depending on specific location on <br />site and seasonal variations. As discussed in Exhibit D, the site will be <br />wet mined and is expected to have minimal irt@act on the groundwater system, <br />Stormwater Control <br />There will be no stormwater discharge from disturbed areas. As such, <br />a stormwater permit from the Colorado Department of Health, Water Quality <br />Control Division, is not required. Most of the stormwater runoff from the <br />-12- <br />
