Request for Modification to Notice of Intent (NOI) File No. <br />P-2008-043 <br />Dear Messrs. Sorenson and Berry: <br />This letter is submitted on behalf of Coloradoans Against Resource Destruction (CARD) <br />Environment Colorado, Clean Water Action, and Information Network for Responsible <br />Mining (INFORM)°and pertains to the Division's consideration of Powertech (USA) Inc.'s <br />Request for Modification to Notice of Intent (NOI) File No. P-2008-043 submitted in September, <br />2009 for the Centennial Mine proposal in Weld County. As the DRMS is aware, these <br />organizations and their members, including local residents and ground water users, have a long- <br />standing interest in Powertech's proposal to conduct in situ leach uranium mining in Weld County. <br />As discussed in detail below, there appear to be serious concerns regarding this recent Request for <br />Modification. <br />According to Powertech's Request for Modification: <br />The objectives of the Section 33 pumping test described in this plan are to: <br />1. Collect site-specific information on geology and groundwater conditions in Section 33 <br />and for the regional hydrogeological characterization; <br />2. Assess the hydrologic characteristics and their lateral continuity within the mineralized <br />production zone(i.e., A2 sand horizon); <br />Assess hydrologic communication in the mineralized zone between the pumping well <br />and surrounding production zone monitoring wells;
