• 6. Refer to the attached Petrotek Report. <br />7. DRMS requires submittal of completion and development reports for all wells. Critical to DRMS <br />review are the geophysical logs, drilling/mud logs, and Powertech's interpretation of their <br />relation to the stratigraphy. <br />Please refer to Completeness Issue Item #7 Attachments. Colorado State Engineers Office (SEO) <br />Groundwater Well Construction and Test Reports are included for all recently drilled wells in section 33, <br />and to be monitored during pumping test activities. Additionally, Powertech has included well logs for <br />these groundwater wells which display well construction details, geophysical logs, and Powertech <br />stratigraphic interpretations. Also included in the attachment are groundwater well development field <br />reports for all wells recently constructed and to be monitored during the pump test. <br />8. The pumping well and monitoring wells installed for and used in the previous pumping test <br />need to be shown on the Centennial Pump Test Plan map. Since these wells are going to be <br />monitored in the pumping test proposed in MD-03, the information listed in item #7 above <br />must also be provided for these wells. <br />Please refer to the Completeness Issue Item #8 Attachment for an updated Centennial Pumping Test <br />Plan Map (Figure 4 of the Centennial Section 33 Pump Test Plan), which includes the locations of all <br />groundwater wells to be monitored at the pump test location. SEO Well Construction and Test Reports <br />• for groundwater wells utilized during the previous pumping test have been submitted to the DRMS in <br />the form of the confidential Surety Reduction Request for NOI P-2007-015. Please refer to that report <br />for well completion details. Development reports and drilling/mud logs were not developed and, thus, <br />are not available for these wells. Information used for completing the screened interval of these wells in <br />the target geologic units was derived from exploration boreholes that were advanced immediately <br />adjacent to the previous pumping test groundwater well locations. It should be pointed out that A2 <br />Sand and WE Sand water levels, and differences in hydrostatic head, in the groundwater wells used in <br />the previous pumping test correlate well with water levels in the same geologic units completed in <br />groundwater wells to be utilized in this proposed pumping test. Powertech's position is that this is <br />adequate evidence that the subsurface geology and hydrogeology at the proposed pumping test site is <br />similar to that at the previous pump test site located about 500 feet away, and that groundwater well <br />screens are completed in the target intervals intended at both pump test locations. <br />9. Provide detailed description of the IN-14-33 core including the results of any geotechnical <br />testing conducted, and provide the plugging and abandonment report for the hole. <br />Core hole IN-14-33 was advanced and abandoned on April 28, 2009, and all available and required <br />information is included as Completeness Issue Item #9 Attachments. <br />r? <br />U
