(Powertech) hereby requests a modification to the "Notice of Intent (NOI) File No. <br />P-2008-043 to Conduct Prospecting" in connection with the Centennial Uranium Project in Weld County, <br />Colorado (the Project). The initial NOI was submitted to the Colorado Division of Reclamation and <br />Mining Safety (DRMS) on June 23, 2008 and the final Authorization to Proceed was granted on August <br />27, 2008 by the DRMS. A modification to the initial NOI was submitted to the DRMS on September 16, <br />2008 and DRMS approval of the modified NOI was granted on October 22, 2008, with an Authorization <br />to Proceed pending placement of the surety bond. <br />Approved prospecting activities covered under NOI File No. P-2008-043 includes: <br />• Install two (2) groundwater monitoring wells for baseline environmental data collection. <br />• Advance eight (8) exploration boreholes to delineate uranium resource in the project area. <br />Approved prospecting activities within NOI File No. P-2008-043 Modification #1 includes: <br />• Install fifteen (15) groundwater monitoring wells for baseline environmental data collection. <br />• Advance one (1) exploration borehole/core to delineate uranium resource in the project area. <br />Proposed prospecting activities within this Modification to the P-2008-043 NOI include: <br />• Powertech plans to conduct an aquifer pumping test utilizing monitoring wells advanced under <br />the P-2008-043 Modification #1, and return the produced water back to the source aquifer. <br />Please refer to Appendix 1 for a detailed description of the aquifer pumping test. <br />During the proposed aquifer pumping test groundwater will be pumped to the surface and routed to <br />mobile Baker tanks for storage, which will be located adjacent to the pumping well until the aquifer <br />pumping test is complete. Following completion of the test, all produced groundwater will then be re- <br />injected into exactly the same aquifer from which the groundwater originated. Powertech is currently in <br />the process of seeking authorization from the Environmental Protection Agency (EPA) to conduct <br />groundwater injection activities through the UIC Class V Program. EPA has issued a draft permit <br />(Appendix 2) which is fully protective of underground sources of drinking water. Powertech will not <br />commence re-injection of produced groundwater until the UIC permit has been obtained, and all <br />provisions within that permit have been met by Powertech. During this process no water will be <br />allowed to discharge to the ground surface. Refer to Appendix 1 for a detailed description of the <br />location, design, and analysis of the groundwater aquifer pumping test. <br />5575 DTC Parkway, Suite 140 Telephone: 303-790-7528 Website: www.powertechuranium.com <br />Greenwood Village, CO 80111 USA Facsimile: 303-790-3885 Email: email@example.com
