7. The existing water features on the Existing Conditions Map, 2 of 7 are difficult to discern. In <br />conformance with Rule 6.4.7(2)(a), please provide a sepazate "Water Features Map" that clearly <br />shows the locations of all surface water and groundwater features in the affected land and <br />surrounding azea that may potentially be affected by the proposed mining operation. Such map <br />should include the location of all springs, wetlands, stock ponds, irrigation canals, lateral <br />irrigation ditches, registered domestic wells, and registered irrigation wells. Please note that the <br />potential exists for adverse impacts to registered groundwater users in excess of 600 feet from <br />the proposed excavation(s). Also, registered wells within the affected land and surrounding azea <br />should be identified as to ownership, well type and size, well pumping capacity, well depth, and <br />volume of water assured by the owner's water right. Please respond. <br />8. In conformance with Rule 6.4.7(2)(b), please clarify the aquifer characteristics of the <br />Broadway alluvium to be affected by the proposed mining and reclamation operation. <br />Specifically, describe the direction of groundwater movement in this shallow alluvial aquifer in <br />and surrounding the area to be excavated; the saturated thickness, hydraulic conductivity, <br />transmissivity, effective radius, and storage coefficient of the aquifer in the area of excavation; <br />whether the aquifer is confined or unconfined; any interaction between surface and groundwater <br />throughout the yeaz; the quality of water produced by registered wells in the affected land and <br />surrounding area; the natural elevation of groundwater in the affected land and surrounding <br />areas; and the range of depth for groundwater in the affected land and suaounding area <br />throughout the yeaz; and the expected depth of groundwater in the affected land and surrounding <br />area during the peak of irrigation season or other such time when the demand for groundwater <br />resources by a variety of domestic water users and/or irrigation water users in the surrounding <br />area is at a maximum. Please respond. <br />9. In conformance with Rule 6.4.7(2)(b), please define the following features: the horizontal <br />distance to surface water features and to groundwater users in the surrounding azea; any sources <br />of existing groundwater recharge in the affected land or surrounding azea; the kind of drawdown <br />that neazby domestic and/or irrigation water users normally have from their use; the groundwater <br />levels in the various wells or the aquifer after use by neazby domestic and/or irrigation water <br />users during a time of maximum demand on the aquifer (presumably during the peak of <br />irrigation season). PYease iespond.- <br />10. In order to better understand the regional surface and groundwater system in the area of the <br />proposed operation, and in conformance with Rule 6.4.7(2)(b), please provide a typical cross <br />section diagram that includes the following features: South Platte River, groundwater table <br />during mining, groundwater table after mining, estimated lake water surface, existing ground, <br />limits of mineable resource, fulton ditch lateral, the closest wetland, the closest domestic <br />groundwater user, and the closest irrigation water user. Please respond. <br />11. h1 conformance with Rule 6.4.4 and Rule 3.1.6(1), please describe the maximum pumping <br />rate necessary to completely de-water all three (3) cells from top to bottom and maintain 284 <br />acres of dry pit surface; and the length of pumping period(s) necessary to completely de-water <br />284 acres of pit surface; the expected drawdown rate of the groundwater surface at the 3 pits; and <br />the natural elevation of groundwater at the pit prior to de-watering. Also, if the operator <br />anticipates using multiple pumps during de-watering and/or pumping from several of more cells <br />
