A. Sorenson, DRMS 4 <br />Response to 3`d Review <br />March 9, 2010 <br />Powertech commitment to commence the aquifer pumping test no earlier than April 15th, 2010, <br />Powertech feels that the freeze protection portion of the bonding calculation should be removed. <br />In order to further justify the removal of the freeze protection portion of the aquifer pump test <br />bond, Powertech will commit to monitoring the long range forecast prior to beginning to store <br />water in the tanks. If abnormally sub-freezing air temperatures are to be expected within the <br />long range forecast, Powertech will postpone commencement of the aquifer pumping test until <br />more seasonal conditions are anticipated. Furthermore, Powertech will install valves so that <br />piping from the well head to the water containment vessels can be evacuated, thus eliminating <br />the potential of water freezing within the piping. <br />Additional Water Containment Vessel: <br />Powertech would like to have the flexibility to bring one more Rain for Rent water containment <br />vessel onsite for use during the proposed aquifer pumping test. Several potential conditions can <br />arise during the aquifer pump test which warrants having an additional water containment vessel <br />onsite, such as a malfunction of the pump or generator. If such a condition were to take place <br />Powertech may need to start the 72 hour test over, which would require additional containment <br />capabilities. In conversations with DRMS personnel, Powertech can have additional tanks on <br />standby for delivery to the pump test site as long as a bond was immediately posted for the <br />additional tank before being brought onsite. However with the geochemical analysis <br />requirements and potential complexities of bond placement, Powertech prefers at this time to add <br />an additional tank to the DRMS reclamation bond calculation. The total number of Rain for <br />Rent water containment vessels to be located at the pump test site now will be five (5). The <br />additional tank will not require the perimeter fence to be any larger. <br />If you have any questions or require additional information, please feel free to contact myself at <br />(303)790-7528 or Michael Beshore at (970)556-5988. <br />Sincerely, <br />Richard E.
