Sorenson <br />Senior Environmental Protection Specialist <br />Division of Reclamation, Mining and Safety <br />1313 Sherman Street, Room 215 <br />Denver, Colorado 80203 ` <br />RE: r?Request for Modification to Notice of Intent (NOI) File No. P-2008-043 <br />Centennial Uranium Project, Weld County, Colorado <br />Dear Mr. Sorenson: <br />MAR 0 4 2009 <br />Division of Reoiama#Wt• <br />Mining and 58W <br />Powertech (USA) Inc. (Powertech) hereby requests the Division of Reclamation, Mining and Safety <br />(DRMS) to make a modification to the Notice of Intent (NOI) File No. P-2008-043 that allows Powertech <br />to conduct prospecting in connection with the Centennial Uranium Project in Weld County, Colorado (the <br />Project). The initial NOI was submitted to the DRMS on June 23, 2008 and the final Authorization to <br />Proceed was granted on August 27, 2008 by the DRMS. A modification to the initial NOI was submitted <br />to the DRMS on September 16, 2008 and DRMS' approval of the modified NOI was granted on October <br />22, 2008, with an Authorization 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 included in this modification to the NOI include: <br />• Construction of an off-channel pit designed to totally contain water produced during <br />hydrogeological aquifer testing. Produced water will evaporate and infiltrate through the <br />substratum underlying the pit location, and ultimately disperse into the atmosphere and <br />throughout bedrock. <br />Powertech intends on conducting an aquifer pumping test in Section 33 of Township 10 North and Range <br />67 West during April, 2009, in order to determine hydrogeologic properties of sedimentary rock units that <br />host uranium mineralization as well as adjacent rock units. Groundwater will be pumped from the target <br />sand unit at a rate of 20 gallons per minute for a maximum duration of 6 days, resulting in a total water <br />discharge quantity of 172,800 gallons. Discharged water will be routed via a pipeline to an off-channel <br />infiltration pit located adjacent to the pumping well. Attachments A and B of this report displays the <br />tabulated and physical location characteristics of the off-channel pit. <br />w? <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: firstname.lastname@example.org
