MANAGEMENT <br />The DRMS' letter dated October 2, 2008 transmitted its adequacy response for the <br />referenced permit revision. On behalf of Bowie Resources, LLC, following are its <br />responses to the DRMS' comments and concerns. <br />2A. Down gradient monitoring wells. <br />1. BRL did not provide cross-sections for the upper perched aquifer because the <br />aquifer is discontinuous. The first paragraph on page 2.04-28 was expanded to <br />discuss the difference between the discontinuous upper perched water bearing <br />and the more continuous lower perched water bearing zone. <br />2. BRL reviewed the single point elevations that were approved on Map 11 (TR-47). <br />The following comments and explanations are provided: <br />a. The elevation for DH-57 was changed back to the approved value. <br />b. The elevation for DH-58a was established by averaging the data for the <br />period from November 1999 through October 2003. During this period the <br />water level in DH-58a dropped. The elevation increased from the prior <br />PR-10 submittal because BRL discovered some data points that were not <br />in the electronic data base. <br />c. The elevation for DH-66 was established by averaging three data points. <br />d. DH-65 located in about the center of section 33 was completed above the <br />D-Seam and the well is dry. Therefore DH-65 was removed from Map 11 <br />and shown as dry on Map 10. <br />e. Because of the change in elevation at DH-57 and DH-58a, Map 11 and <br />Map 11-1 were amended and are enclosed. <br />f. On Map 10, average elevations were utilized to update the single point <br />source elevations for DH-57a, DH-58 and DH-67-abv.
