The <br />only issue) for staff is the increase in lake size from 4.22 to 5.2 acres. The increase in size itself <br />is not an issue, but the additional exposure of 0.98 acres of groundwater is. The County has a <br />couple of options in regard to the additional water exposure: A} demonstrate that there are <br />sufficient water rights already in place to cover the additional exposure or not required at all, or <br />B} reduce; the final configuration of the lake back to 4.22 acres by filling in additional area, or C} <br />Another :scenario if water rights must be secured is to commit to keeping the pit at approximately <br />4.22 acres until documentation verifying the additional evaporation has been supplied to the <br />Division. <br />Rio Blanco County should respond as quickly as possible to ensure that staff has time to review <br />the respl~nse and render a Decision no later than July 15`n <br />If you need additional information, please contact me at the Division of Minerals and Geology, <br />Grand Junction Field Office, 101 S. 3rd St., Suite 301, Grand Junction, Colorado 81501, <br />telephone no. 970.241.1117. <br />Sincereiy, , <br />-~%iJ <br />G.
