Mr. Michael Cunningham <br />CDRMS <br />November 26, 2013 <br />the addition of tree, shrub and forb species to the reclamation seed mix could enhance <br />the site's use as wildlife habitat. Please respond. <br />Response: <br />12 <br />UMC contacted Arkansas Valley Seed to enquire which seed mixes were suitable for <br />our location. The seed mix shown in the table below has been recommended by <br />Arkansas Valley Seed. They also indicated that this seed mix has been accepted by the <br />Division in other reclamation projects. <br />Species <br />Scientific Name <br />Variety <br />Pis Ibs /Acre <br />Yarrow <br />Achillea lanulosa <br />0.1 <br />Groundsel <br />Senecio atratus <br />0.1 <br />Lupine <br />Lupinus perennial lupine <br />1.0 <br />Slender wheatgrass <br />Elymus trachycaulus <br />San Luis <br />1.4 <br />Nodding brome <br />Bromus anomalus <br />2.5 <br />Sheep fescue <br />Festuca ovina <br />Covar <br />0.5 <br />Hard fescue <br />Festuca ovina duriuscula <br />Durar <br />0.5 <br />Red fescue <br />Festuca rubra <br />Penniawn <br />0.5 <br />Tufted hairgrass <br />Deschampsia caespitosa <br />0.5 <br />Redtop <br />Agrostis alba <br />0.1 <br />Blue wildrye <br />Elymus glaucus <br />1.75 <br />Muttongrass <br />Poa fendleriana <br />0.5 <br />TOTAL pls Ibs /acre (drilled) <br />9.45 <br />18. The Applicant is proposing to place 18 inches of suitable material over the TSF prior to <br />seeding. Is the material to be placed over the TSF currently on the site? If so, where is <br />the material being stored and what is the source of the material? If the material will be <br />imported, then the Applicant will need to comply with the requirements of Rule 3.1.5(9) <br />regarding the importation of inert fill material. <br />Response: <br />The text will be revised as follows. <br />Tailings in the TSF will be covered by up to 8 inches of embankment material. This <br />material originates from the sides of the embankment and consists of an estimated <br />3,600 yd3. Then, approximately 4 inches of topsoil will be placed over this material and <br />seeded using the specified seed mix. Approximately 1,400yd3 of topsoil and suitable <br />plant growth material will be required. This material was removed during TSF <br />construction and exists at the site as shown in Figure 6 -2 (Attachment 2). No imported <br />material will be required. <br />19. The final cap placed over the TSF must be designed to have positive drainage. Please <br />provide a cross section drawing showing that the cap will have a crown and will provide <br />positive drainage across the TSF. <br />
