section junctions. Well 8897-F belongs to Albert Claunch and is 345 feet deep. Well 5873-F <br /> belongs to Albert Claunch and is 779 feet deep. Both wells are permitted for irrigation use. <br /> 2. Groundwater <br /> The site will mine the Quaternary sand and gravel deposit found in the San Luis Valley derived <br /> from alluvial fans draining the San Juan Mountains to the west. Groundwater is encountered <br /> >100 feet below the undisturbed ground surface in undifferentiated alluvial aquifers of the San <br /> Luis Valley. It is not expected that groundwater will be encountered during any phase of mining. <br /> 3. Water Consumption for the Operation and Water Rights <br /> Groundwater is unlikely to be encountered during any phase of mining at the Garrett Pit; <br /> however, a Substitute Water Supply Plan(SWSP) is in place due to requirements dictated by <br /> Conejos County. Because the alluvial gravel to be mined is dry, no water losses will occur from <br /> the gravel resource during mining. <br /> Dust will be controlled by water. Water will be used as needed to spot eliminate any problem <br /> dust areas. 0.5 acre-feet per year will be allocated to dust control, or 0.04 acre-feet per month. <br /> Any water required for dust mitigation will be purchased and brought on site by an independent <br /> operator. <br /> Therefore, total annual depletions for the gravel mining operations are estimated to not exceed <br /> 0.5 acre-feet per year. <br /> King Pit Gr,1—k-ki and Aswdales.PLIXt <br /> February 2018 G-2 <br />
