Martha Fidanque, and is permitted as 2730033 and 273274. No depth <br />information is available. <br />2. Mining at this site will be limited to depths of not to exceed 45 feet below existing <br />ground level and expected to be about 30 feet. This places mining well above <br />the known water table, including any alluvial aquifer of Mud Creek. <br />3. Mining will not significantly impact sources of ground water, based on standard <br />engineering design and activities. <br />4. Other data available: No other information for recorded water rights was <br />available from published sources. <br />5. Aquifers and watersheds in this area: The only recognized aquifer in the area is <br />the Morrison Formation, approximately 500 feet below surface; the alluvial <br />aquifer associated with Mud Creek is NOT considered a feasible or significant <br />source of water. However, mining will not be deeper than a minimum of 40 feet <br />above Mud Creek at this point. No activities associated with the mining are <br />expected to impact on the creek or on other aquifers. The overburden (soil) and <br />the sand and gravel are not significant aquifers in this area. Although various <br />springs have been found to have developed in that material due to past <br />irrigation practices, the recent BuRec project has ended those practices and <br />springs have or are drying up. Based on the location and depth of other known <br />wells in the area, the mining activities proposed will have no reasonable <br />potential for any adverse impact. There will be no blasting at this site. <br />6. Prevention and mitigation actions: As discussed above. As necessary, storm <br />water pollution prevention and management actions, including erosion and <br />sedimentation control, are implemented as required by the Colorado Discharge <br />Permit System storm water general permit for which coverage is current as of <br />2010. This meets the requirement for an NPDES permit and covers dewatering <br />and process (wash) water as well as storm water. Overall design of the pit was <br />done to plan for a minimum impact on surface and ground water. Pit area is not <br />being currently irrigated, nor is irrigation actually needed for reclamation. <br />G-3. PROJECT WATER REQUIREMENTS: <br />Water use for extracting and processing aggregates from the pit will be low, <br />amounting to less than 6 acre-feet per year under worst case conditions. This water <br />will come from the temporary industrial use of agricultural water from existing water <br />rights for the property, as discussed above. Based on data available on historic <br />irrigation of the property, of irrigated land, it may be necessary for the landowner to <br />legally dry up approximately 3 acres of land in order to provide augmentation, if <br />such is necessary, and the landowner is willing to do so, since more than that <br />amount of land is used for mining and plant sites and cannot be irrigated. Water is <br />stored on-site for use as necessary in case mining operations using water are <br />performed outside of the traditional irrigation and water use season for the site and <br />water rights. <br />The primary uses of water on the site are dust control, washing of product, and <br />compaction of backfill. <br />Exhibits for 112(c) AM-02 Application - M-1994-108-2010- Page 39
