JV offers <br />the following additional information addressing the Division's questions and requests. <br />6.4.7 Exhibit G - Water Information <br />1. Rule 6.4.7(3) requires the Applicant to provide an estimate of the project water requirements for <br />the development, mining, and reclamation phases of the project. Please provide an estimate of the <br />volume of water that will be required to fill the reservoir. Also, please provide the anticipated <br />source of water that would be used to fill the reservoir. <br />We are providing the information included in Exhibit G for reference and also including the <br />estimated volume of water to fill the reservoir as follows: <br />Water Requirements <br />Water use at the Journey Ventures Pit will include evaporation from exposed groundwater, dust <br />control of haul roads and stockpiles, and water retained in material removed from the site. <br />Evaporative Loss <br />Evaporative losses are dependent on the exposed water surface area, which may shift <br />throughout the mining operation, but will not exceed the maximum. Exposed surface area at the <br />Journey Ventures pit will include groundwater exposed in the dewatering trenches and <br />discharge settling pond. The maximum exposed surface area at the site during mining is <br />estimated at 0.38 acres. Journey Ventures, LLC plans to keep the site dewatered throughout <br />the life of the mine. <br />Evaporation data was taken from NOAA Technical Report NWS 33, Evaporation Atlas for the 48 <br />Contiguous United States. The annual gross evaporation was determined to be 45 inches for <br />V m 1400 W 122"d Avenue - Suite 120 • Westminster CO 80234 • Ph: 303-457-0735 • Fax: 303-920-0343
