ROBI NSON BRICK <br />A Division of General Shale Brick <br />September 19, 2008 <br />Division of Reclamation, Mining and Safety <br />1313 Sherman St., Rm. 215 <br />Colorado Springs, CO 0903-2208 <br />Attention: Mr. ared Ebert <br />Subject: Apache Mine (M-1978-009) Pit Water <br />Dear Mr. Ebert, -_ _ ---- -_- ---? -- - <br />SCI <br /> <br />Robinson Brick Company is in receipt of your inspection report related to the Divisions <br />inspection of the above referenced mine on June 9, 2008. Your inspection report indicates a <br />potential "problem" related to the exposure of groundwater in a pit. excavation at the mine. We <br />are in agreement that a portion of water contained in our south pit is likely related to groundwater <br />inflow. We are confident that the flow is from the upper Dawson Formation, and we have <br />initiated efforts to obtain a well permit. <br />We have retained the services of Martin and Wood Water Consultants, Inc. (M&W) and Anne <br />Castle, of Holland and Hart, to assist us through the well permitting process. To date we have <br />determined that the subject mine is within the Upper Black Squirrel designated water basin, and <br />as such will be subject to the regulatory requirements of that water basin. We are currently <br />evaluating those requirements. Further, we have learned that the State Engineer's office maps do <br />not currently recognize that the Dawson aquifer exists at the subject property, so this issue must <br />certainly be addressed during the well permitting process. M&W have engaged a water broker <br />who is actively pursuing augmentation water. Once appropriate augmentation water is secured, <br />we can formulate a Substitute Water Supply Plan and ultimately a well permit application. We <br />anticipate the entire process may take up to 12 months to complete and therefore respectfully <br />request that you extend the "Correction Date" listed in your inspection report. <br />If'you Have any questions regarding this correspondence, I can be reached at 303-783-3061. <br />Respectfully, <br />Robinson Brick Company <br />Gregory W.
