Powertech submits application to EPA for permit to inject mining wastes into deep aquifer - Letter to landowners informing them of Powertech's intent to obtain a Class I Underground Injection Control permit from the EPA for the injection into deep disposal wells of waste streams from the proposed Centennial project  - Terence P. Walsh, Project Manager, Powertech (USA) Inc. - November 23, 2010 (PDF 658 KB, 2 pages)  In-situ leach uranium operations generate high volumes of liquid wastes.  These wastes can contain uranium, radon, radium, polonium, bismuth, arsenic, molybdenum, selenium, lead, barium chloride, hydrogen sulfide, laboratory wastes, drilling fluids, and other chemicals and heavy metals.  Powertech proposes to drill up to six disposal wells and inject the wastes 8,300-9,000 feet below the surface at pressures of up to 1,400 pounds per square inch.  The wells will penetrate the Laramie Fox Hills aquifer.  To prevent the wastes from migrating up the well borehole and contaminating the Laramie Fox Hills, the space between the well casing and borehole wall is filled with cement.

 

Explanation of need for "aquifer enhancement" before in-situ leaching can be conducted in majority of Centennial project - Excerpt from Section 17 Additional requirements for development properties and production properties - NI 43-101 Preliminary Assessment of Centennial Uranium Project - Prepared by SRK Consulting Engineers and Scientists - August 13, 2010 (PDF 105 KB, 6 pages)  "The current ISR development plan for the Centennial project includes aquifer enhancement by raising the water table through fresh water injection on the well field perimeters of six mine units. Raising the water table will promote saturation of the ore bodies and sufficient hydraulic head above the mineral to maintain the dissolved oxygen at the levels required to recover uranium... Aquifer enhancement and control of mining solutions is proposed through development of a hydraulic fence that may be operated throughout mining and restoration of the well field. Preliminary design of the proposed hydraulic fence consists of a ring of freshwater injection wells located approximately half the distance between the mining patterns and the monitor well ring...  The injection wells of the hydraulic fence will likely be supplied with Colorado-Big Thompson (CBT) water acquired through purchase... No modeling has been completed by Powertech to assess the effect of the hydraulic fence on the surrounding water resources during operation." 

 

Letter from Cheryl Linden, Colorado Office of the Attorney General, to John Fognani, attorney for Powertech (USA) Inc., regarding modification #2 to Notice of Intent to Conduct Prospecting P-2008-043, stating that assertions made by Mr. Fognani are incorrect, including his statements that members of the public should not be allowed to express their concerns to the Colorado Division of Reclamation, Mining and Safety regarding "prospecting" activities, that House Bill 08-1161 does not authorize the DRMS to hire a third-party expert to review Powertech's current activities, and that Powertech has not been conducting baseline characterization - June 1, 2009  (PDF 229 KB)

 

Letter from Allen Sorenson, Colorado Division of Reclamation, Mining and Safety, to Richard Blubaugh, Powertech (USA) Inc., regarding modification #2 to Notice of Intent to Conduct Prospecting P-2008-043, accepting Powertech's withdrawal of the plan to dispose of pump test wastewater in an unlined infiltration pit, informing Powertech that an alternate plan to store the wastewater in tanks and reinject it into the aquifer will require the submittal of a new modification request, stating that the Division has determined that many of Powertech's previous activities are baseline site characterization even though Powertech's attorney insists they are not, stating that the Division will hire a third-party expert to assist with oversight, monitoring, and review of Powertech's baseline site characterization plan and activities over the objection of Powertech's attorney, and asking Powertech to clarify whether the approximately 14,000 water quality data points collected from eight samplings of 21 monitoring wells in 2007-2008 and other aquifer test results will or will not be included in a baseline characterization submitted with any future permit application - June 1, 2009 (PDF 567 KB)

 

Letter from Jeffrey Parsons, Western Mining Action Project, representing Coloradoans Against Resource Destruction and three other organizations, to the Colorado Division of Reclamation, Mining and Safety, responding to April 14-15 letters from Powertech and its attorney, and pointing out that Powertech has not submitted an application for an alternative wastewater disposal method for its planned aquifer pump test, asserting that Powertech is attempting to avoid certain provisions of House Bill 08-1161, urging the DRMS to reject Powertech's attempt to exclude the public and local governments from commenting on pre-mining activities, and arguing that the DRMS has not reviewed or approved Powertech's plans for aquifer pump testing - May 8, 2009  (PDF 31 KB)

 

News Release - "Powertech to Submit Updated Technical Reports" - Powertech Uranium Corp. - May 7, 2009 (PDF 139 KB)  Note: The British Columbia Securities Commission is reviewing Powertech's securities filings and press releases, and has determined that the company's 2008 Annual Information Form does not comply with regulations regarding disclosure.  The BCSC also required Powertech to disclose that it has not conducted independent preliminary feasibility studies for either the Centennial or Dewey-Burdock projects.
