Request for Modification to Notice of Intent (NOI) File No. P- 2008 -043 Dear Messrs. Sorenson and Berry: This letter is submitted on behalf of Coloradoans Against Resource Destruction (CARD) Environment Colorado, Clean Water Action, and Information Network for Responsible Mining (INFORM)"and pertains to the Division's consideration of Powertech (USA) Inc.'s Request for Modification to Notice of Intent (NOI) File No. P -2008 -043 submitted in September, 2009 for the Centennial Mine proposal in Weld County. As the DRMS is aware, these organizations and their members, including local residents and ground water users, have a long- standing interest in Powertech's proposal to conduct in situ leach uranium mining in Weld County. As discussed in detail below, there appear to be serious concerns regarding this recent Request for Modification. According to Powertech's Request for Modification: The objectives of the Section 33 pumping test described in this plan are to: 1. Collect site - specific information on geology and groundwater conditions in Section 33 and for the regional hydrogeological characterization; 2. Assess the hydrologic characteristics and their lateral continuity within the mineralized production zone(i.e., A sand horizon); 3. Assess hydrologic communication in the mineralized zone between the pumping well and surrounding production zone monitoring wells;
