r <br />M <br />POWERTECh (USA) INC. <br /> <br />August 1, 2008 <br />Allen C. 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: Needed Items for NOI # P-2008-043 (Non-Confidential Portion) <br />Centennial and Indian Springs Projects <br />Weld County, Colorado <br />Dear Mr. Sorenson, <br />NON CONFIDENTIAL <br />Z <br />RECEIVED <br />AUG 0 4 2008 _-`_ <br />Division of Reclamation, <br />Mining and Safety <br />This letter has been prepared in response to the Division of Reclamation, Mining and Safety (DRMS) <br />letter to Powertech (USA) Inc. (Powertech) dated July 22, 2008, which states that the Powertech <br />application for Notice of Intent (N01) File Number P-2008-043 is incomplete. Contained within this <br />package you will find the non-confidential portion of additional information needed for DRMS to <br />complete its review of the application. <br />1) Item number 6 of Section III of the N01 application states that Powertech proposes to drill holes <br />up to 12 inches in diameter. In the case of this exploration activity, Powertech will be advancing <br />exploration boreholes at a diameter of 6.5 inches and monitoring wells at a diameter of 8.75 <br />inches. As you indicated in your letter dated July 22, 2008, these drill hole diameter <br />measurements have been used for the DRMS calculation of plugging and abandonment costs for <br />the reclamation bond, and Powertech agrees with this. Powertech is in the process of securing <br />DRMS bond placement for these activities and will be forwarded as soon as possible. <br />2) Item number 2 of Section IV of the NOI application requires Powertech to provide a description <br />of the native vegetation in the areas to be disturbed by prospecting activities, which can be part <br />of the public N01 file. Attachment A of this package describes the vegetation communities <br />present within the affected prospecting areas proposed by Powertech, and these descriptions <br />can be available in the public NOI file. <br />3) Powertech has placed the details of the proposed groundwater monitoring well locations in the <br />confidential section of the N01. The rational and reasoning for this is because the proposed <br />groundwater monitoring wells are located within the uranium ore body. <br />4) Item number 3 of Section III of the N01 incorrectly states the quantity of earthen material that <br />Powertech estimated to be removed in order to conduct the prospecting activities. We agree to <br />the bond calculation estimate provided by DRMS of 170 bank cubic-yards of excavated material <br />for the construction of drilling mud pits. <br />5575 DTC Parkway, Suite 140 Telephone: 303-790-7528 website: www, <br />Greenwood Village, CO 80111 USA Facsimile: 303-790-3885 Email:
