The DRMS is supportive of this <br />aspect of the plan; use of native soil excavated from Oxide Pond during the Eagle Park Reservoir project <br />has benefited reclamation along the Highway 91 frontage. However, DRMS will require sampling and <br />analysis for metals and agronomic properties prior to deployment of the materials from the 1-Dam <br />stockpile, and may limit the locations for use of this material depending on the results. Metals analysis, <br />at a minimum, must include lead, manganese, zinc, copper, cadmium, and total metals digestion. Also, if <br />the soil remains in stockpile in October 2008, DRMS will require that it be seeded prior to the end of the <br />month." <br />Climax will perform sampling and analysis of the native materials removed for metals and agronomic <br />properties prior to deployment of these materials from the 1 Dam stockpile. The metals analysis will <br />include lead, manganese, zinc, copper, cadmium, and total metals digestion. Results of this soils analysis <br />will be forwarded to the DRMS prior to any use of this material for reclamation purposes. If the soil <br />remains in stockpile past October 2008, Climax will apply the Climax seed mix to the stockpile prior to the <br />end of the month. <br />2) "Section 3.5 of the TR-15 application states that areas to be revegetated following the completion of the <br />project will be seeded with perennial rye. This type of seeding is suitable for areas requiring interim <br />stabilization and that will be redisturbed in the near term for some other pending project, such as the <br />stockpile discussed in item no. 1 above, but is not suitable for areas to be revegetated over the longer <br />term. Please provide a rationale for seeding with rye only, or commit to seeding with the Climax seed <br />mix that is approved in the permit at the time that the seeding occurs." <br />Areas to be re-vegetated following the completion of the project will be seeded with the approved Climax <br />seed mix not the perennial rye as erroneously noted in our TR14 application.
