<br />• 2.0 SCOPE OF WORK - OBJECTIVES <br />The goal of this study is to satisfy all regulatory requirements con- <br />cerning the baseline groundwater hydrology role in the permit application <br />to be submitted to O.S.M. and the Colorado Mined Land Reclamation Board. <br />More specifically, this report combines the previous hydrologic work pre- <br />formed by VTN and the new supplemental work conducted by Morrison-Knudsen <br />to be included in the permit application. Included in this report is the <br />one year baseline data collection requirement, which amends the preliminary <br />data presented in the initial report. The necessary additional groundwater <br />data has been obtained through the following tasks: Installation of 7 <br />monitoring wells (2 dual completions and 3 single completions), conduction <br />of 3 pump tests (two in the lower coal and one in the upper coal), quarterly <br />water quality monitoring for one year, monthly static water level monitoring <br />for one year, and final data assessment through computer modeling and other <br />interpetive methods. The completion dates of the above tasks are presented <br />below: <br /> <br />Task <br />Completion Date <br />• lJell Installation 2-81 <br />• Pump Tests 2-81 <br />• Quarterly Water Quality Monitoring 4-81 <br />• Monthly Static Water Level Monitoring 4-81 <br />• Fina•1 Interpretation 5-81 <br /> <br />2 <br />
