~ • iii iiiiiiiiiiiiiiii ~a,~~-~~ . APPLICATION FOR AMENDMENT OF 112 PERMIT NUMBER M-84-041 EXHIBIT J - VEGETATION INFORMATION Vegetation cover is classified as "rare". Natural plant species are mostly shrubs dominated by sagebrush and greasewood. Some lesser shrubs are present such as winterfat, low rabbit brush and salt brush. Also present are Russian knapweed, Russian thistle and mustard. A substantial stand of mature pinyon and juniper are present on the top of the ridge covering the majority of the area to be affected by the mining operation of this application. It is estimated that the stand is comprised of 608 pinyon and 408 juniper. 10 to 158 of the juniper trees are dead. EXHIBIT K - CLIMATE The area of the site is classified as Zone VI climate. This describes an area of less than 12" of annual precipitation, moderately cold climate at elevations ranging from 6500 feet to 7200 feet. Seasonal temperatures are reported to range from 18 F to 66 F, however, temperatures considerably colder and warmer have been observed at the site. The area is located in the rain shadow of the Flat Top uplift to the west which appears to cause precipitation to "jump" the area. Considerably more precipitation may be observed both to the west and to the east of the site than is experienced on the site. EXHIBIT L - RECLAMATION COSTS Reclamation costs for this site are estimated as follows: (a) machine time: buldozer to spread topsoil-overburden estimated at 4 hours per acre at $75/acre = $300/acre. It is estimated that a track mounted backhoe would reclaim the haul road at approximately the same cost per acre. (b) labor: one manhour per acre at gross cost of $15.00/hr (c) seed $2.00/pls @ 26 pls/acre = $52/acre. (d) 108 miscellaneous and contingency = $37/acre. Total estimated cost per acre = $404 Maximum area of disturbance = 15 acres. 15 acres at $404/acre = $6060
