{•" . u Four • A vegetation map must be provided immediately. The map should adequately indicate vegetation prior to mining. Baseline vegetation data for cover, producitivity, and shrub density must also be submitted. Irrigation is alluded to "if needed" but no details and schedule for the irrigation system are included. Pest control and disease control measures are not addressed. Introduced species are included in the plan. A justification for the use of introduced species is required. The exclusive use of crested wheatgrass for topsoil stockpiles must also be explained, since problems with the competitiveness of this species might arise. The scientific names of the species and subspecies to be used in the seed mixtures should be provided. The statement regarding the absence of any threatened or endangered vegetative species in the permit area needs to be be sub- stantiated. Seed mixtures should be more specifically correlated to the acreage of disturbed areas. Of the three seed mixtures proposed, the latter two mixtures have low seeding rates which might result in difficulties in establishing the vegetation. The seeding rate for American Vetch needs to be clarified (i.e., one or two lbs PLS/acre?). Seeding rates for each shrub species should be specified. Seeding rates, use of introduced and native species, and species adaptability to soil textures, quantity, quality, and toxic materials in the soil need to be considered in relation to the success of establishing revegetation. The applicant also needs to substantiate that revegetation success is feasible with a topsoil depth of four inches, as opposed to six inches or greater. The measures proposed to be used to determine the success of revegetation as required in 30 CFR 817.116 must be identified and discussed. R discussion of the methods and machinery used for scarifying resoiled areas for seed bed preparation needs to be provided. R time table indicating the projected dates which coincide with a planting date is partially provided, but an identification of the season for pre- paration and planting should be made. The "best" season of planting was identified in the first mine plan but not committed to. Such planting dates are available from the SCS. Section 817.13 requires the first normal planting period. Spring planting could be completed if erosion control requirements dictated such a planting time. More information should be submitted for the following items in this paragraph. No planting methods are stated. Fertilization methods, if used, are not discussed. No indication of how much mulch, how and at what rates it will be applied, or how it will be anchored is provided. Fish and Wildlife Resources Information There is additional information available from the Division of Wildlife that will help provide a more accurate description of the fish and wild- life Yesources in the mine area. This information includes RB 1091 Wildlife Distributi~ori Maps by couhty.and Population Status printbuts by geographic coordinates from the Latalong computer program. All of this
