MANAGEMENT <br />The DRMS' letter dated May 2, 2014 requested additional information. On behalf of <br />Bowie Resources, LLC, enclosed is the revised data. <br />Please remove from consideration the relocation of the E. & W. Diversion ditches <br />around gob pile #2. Those two ditches have been re- submitted as part of TR -89. <br />1. DRMS: The State Engineer's current policy requires that, unless captured in priority, all <br />impounded water in an overappropriated stream basin (such as the North Fork) be <br />released to the stream system within a maximum of 72 hours after it is impounded. <br />Please refer to the comments received from the Division of Water Resources regarding <br />PR -14 (previously forwarded to you). Please update the permit section on water <br />depletion (beginning on page 2.04 -119), and verify that the current augmentation <br />plan is sufficient for the increased evaporative loss associated with the expanded <br />surface area of Pond D, and that Pond D will be dewatered within 72 hours of <br />waterbeing impounded or include a demonstration that the current augmentation <br />plan provides for retention of water beyond 72 hours. <br />BRL: The expansion of Pond D has been revised. The primary spillway elevation will <br />be held current at 5972', and the remainder of the pond will be expanded in terraces <br />to provide the required water storage amount. Page 2.05 -40 has been updated to <br />more clearly state the State Engineer's policy, which is that water not captured in <br />priority be released within a maximum of 72 hours. A revised map for review <br />purposes showing the plan and profile of the proposed Pond D expansion is <br />attached. <br />
