Permit M-1977-493—Climax Mine <br /> successful reclamation at Climax. The need for other amendments will be determined from soil analyses and/or <br /> reclamation site characteristics on a site-by-site basis. <br /> E-6.3.1 Soil Analysis <br /> Prior to application of reclamation cover, materials may be sampled and analyzed. Cover materials that could be <br /> tested include pit overburden and salvaged reclamation cover soils. Soil analyses may include, but are not limited <br /> to, acid potential, neutralization potential, organic matter, nutrients (nitrogen, phosphorous and potassium), and <br /> texture. These analyses will be used to determine the need for lime additions. <br /> E-6.3.2 Fertilizer <br /> No amendments are proposed. Recent experience at similar sites shows that use of inorganic fertilizer for native <br /> species revegetation provides no benefit and may be detrimental. <br /> E-7 Revegetation <br /> Revegetation at Climax has included seeding with various seed mixtures, as well as direct transplanting of trees, <br /> shrubs, and herbaceous vegetation. Alternate plant species will be substituted for species of the same life form if <br /> the originally identified species becomes unavailable. The alternate species shall be added at a rate to provide the <br /> same PLS/sq ft as the species being replaced. The following sections detail the different revegetation techniques. <br /> E-7.1 Seeding <br /> Reclamation areas, with the exception of talus, will generally be seeded as a part of revegetation efforts. One of <br /> several seed mixtures will be used depending on the characteristics of the reclamation area: <br /> • Reclamation areas that will be disturbed within five years of initial seeding may be stabilized with a temporary <br /> seed mixture (Section E-7.1.1). <br /> • Reclamation areas above the tree line will be seeded with an alpine seed mixture (Section E-7.1.3). <br /> • Reclamation areas with potential hydric soils or saturated soil conditions may be seeded with a hydric seed <br /> mixture (Section E-7.1.4). <br /> • All other reclamation areas will be seeded with the upland standard seed mixture (Section E-7.1.2). <br /> A concerted effort will be made to acquire the recommended seed mixture; however, species availability can vary <br /> from year to year. If substituting species is necessary, a list of alternative species has been included for each of <br /> the recommended seed mixtures in this section. The seed mixtures are designed to maintain a diversity of life <br /> forms (e.g., perennial grasses, perennial forbs, and woody plants)should there be a need to revise the seed <br /> mixture with alternative species. <br /> E-7.1.1 Temporary/Stabilization Seed Mixture <br /> The temporary/stabilization seed mixture (Table E-2) may be used in reclamation areas that require temporary <br /> cover or stabilization. This seed mixture may be broadcast or hydroseeded at a target rate of 100 pure live seeds <br /> per square foot (PLS/sf). <br /> Table E-2: Temporary/Stabilization Seed Mixture <br /> Desired <br /> Species Avg.
