5.4 Revegetation <br /> Revegetation will occur concurrently with the mining process as is practical. Care will be <br /> taken to regrade and provide reclaimed slopes such that revegetation regrowth may occur to <br /> help comply with state and erosion standards. Seeding and grassing activities will take place <br /> immediately upon completion of reclaimed slopes (season permitting) whenever practical <br /> size areas become available and free from mining activity. Areas not planned for revegetation <br /> include Phases 1, 3, and 4 as they will become below-grade ponds. Based on SCS guidance <br /> for other local projects having similar surficial soils, the following revegetation procedures <br /> are anticipated: <br /> • Grass seed will typically be planted in unfrozen soil between October 1 and April <br /> 30 <br /> • Grass seed will typically be planted with a grass drill, or where necessary, with a <br /> broadcast seeder <br /> • The proposed seed mix and application rates in pounds of pure live seed per acre <br /> are described on the following pages <br /> • Weed control practices will be implanted as required. <br /> The above procedures may be modified as conditions dictate. Weeds will be mowed before <br /> they go to seed during the first growing season. Plant species anticipated to establish <br /> themselves naturally along the shorelines include cattails, willows, cottonwoods, and <br /> bulrushes. Proposed seed mixtures to be used on site where appropriate are listed below. <br /> Availability may dictate the need for substitution. The anticipated seed mix to be used for <br /> Three Bells Mine revegetation is shown in Table 2. <br /> Table 2: Seed Mix for Three Bells Mine <br /> Species Preferred Varieties Rate Lbs./Acre PLS Seeded/Acre <br /> Planted (Drilled 1) <br /> Green needlegrass <br /> Lodorm 2.00 362,000 <br /> Stipa viridula <br /> Indian ricegrass Paloma 2.00 376,000 <br /> Achnatherum hymenoides <br /> Slender wheatgrass <br /> Primar, Revenue 2.00 320,000 <br /> Elymus trachycaulus <br /> Thickspike wheatgrass <br /> Critana 2.00 372,000 <br /> Elymus lanceolatus <br /> Western wheatgrass <br /> Arriba, Barton 5.00 630,000 <br /> Pascopyrum smithii <br /> Lewis flax <br /> Linum lewisii <br /> Appar 1.00 285,000 <br /> Upright prairie coneflower <br /> Ratibida columnifera None 0.25 225,000 <br /> GEI Consultants,Inc. 15 June 2014 <br /> Three Bells Mine Reclamation Permit Amendment <br />
