Page 5, Item #9i: In a letter dated October 12, 2010, the DRMS determined that Aero 317 xanthate is NOT a <br />designated chemical and will NOT require an Emergency Response Plan. <br />Page 5, Item #9j: Exhibit C has a ground water monitoring well sampling plan that is accurate and will stand. The <br />small diameter of the monitoring well (2.375" dia.) provides for appropriately purging three well bore volumes with <br />the described bailer. <br />Page 5, Item #9k: VR accepts the DRMS requirement that riprap be inert, durable and non-slaking. <br />Page 5, Item #91: Exhibit D and the Reclamation Cost Schedule have been revised to include a 25% contingency to <br />the process water evaporation operation. Importing fill into the tailings beach to facilitate positive drainage will not <br />be necessary. As the captured water is evaporated, the embankment crest may be graded into the beach zone to level <br />the bench and facilitate drainage. Exhibit D has been revised to reflect this technique. <br />Page 5, Item #9m: This item is not applicable to the current conditions. VR will most likely not accept a limited <br />approval building upto the Barrier Bench level, corresponding to the top of the concrete barrier. In our last <br />Technical Revision submitted on November 10th, we proposed a stability enhancement design that would accept a <br />compromise approval condition with a buildout through Bench #2. This buildout level will have a corresponding <br />incremental, maximum disturbance reclamation cost estimate that can be found in the revised Exhibit D, attached. <br />Page 5, Item #9n: Understood. Exhibit D has provided the appropriate reclamation plan for the selected post <br />mining land use. <br />This, along with the previously submitted Technical Revision of November 10", concludes a thorough response to <br />all of the items contained in the DRMS' September 8th Second Adequacy Review.
