Letter to Richard Blubaugh 3 March 31, 2009 <br />Centennial Project Recent of Modification MD-02 File No. P-2008-043 <br />5. If DRMS approves Powertech's proposed modification, DRMS will require submittal of well completion <br />and development reports for the new pump test wells and water quality data from a minimum of one sample <br />from each well prior to making a final decision on the proposed water disposal pit. Powertech must notify <br />DRMS at least five working days prior to sampling of these wells so that the sampling can be observed and <br />split samples collected. Powertech will be required to pay for the analysis of the DRMS split samples. If the <br />stratigraphy and/or water quality in the new wells so indicates, the mixing analysis must be adjusted to <br />incorporate the information and the revised analysis provided for DRMS review. If and when the disposal of <br />pump test water is approved, DRMS must be provided five working days prior notice of commencement so <br />that inspections can be scheduled. <br />6. The proposal contained in MD-02 is for piping of the pumped water to the off-channel disposal pit. Pump <br />operation will be twenty four hours per day for six days. Provide the personnel schedule for operation and <br />observation during the proposed test. Provide a design and specification for the pipeline from the pumping <br />well to the disposal pit. DRMS will require that the pit, and possibly the pipeline corridor be fenced to <br />prevent access by wildlife, livestock, and people. Provide a design and specification for fencing. <br />7. Many of the activities being conducted or proposed to be conducted under prospecting notice P-2008-043 <br />are baseline characterization under the Colorado Mined Land Reclamation Act at 34-32-112.5(5)(a). <br />Pursuant to section 34-32-112.5(5)(a), DRMS will retain an independent third party reviewer to oversee <br />baseline site characterization, monitor field operations, and review the information collected, developed, or <br />submitted. In the near future, DRMS will forward to you the required contract. <br />8. Enclosed please find copies of comment letters on MD-02 from the Western Mining Action Project and <br />Weld County. Please review and provide Powertech's position on each issue raised in each letter. <br />DRMS is deferring the cost estimating to determine the amount of required bond for the proposed <br />modification until the issues in this review letter have been resolved. You may not commence operations <br />proposed in MD-02 until these issues have been resolved and bond has been submitted and you have been <br />notified in writing that the bond has been accepted by the DRMS. <br />If you have any questions, please contact me at 303-866-3567. <br />Sincere , <br />Allen C.
