Soil removal operations will be conducted in a manner that maximizes recovery of suitable resources for soil reconstruction and minimizes physical handling. FWI area salvage will be conducted to the extent possible. Where suitable soil is available, it will be salvaged to a minimum depth of six inches or the bottom of the A-horizon, whichever is greater. Whenever possible, suitable A-horizons will be salvaged, handled and stoned separately from subsoil materials. Complete salvage of the A-horizon will be perforated since it serves as a "reservoir" for important macronutrients and micronutrients essential to plant growth and development. Organic material accumulations in the O-horizon and A-horizon also serve to promote plant growth through improved nutrient retention and better moisture availability. Suitable A-horizon materials will normally be salvaged in their entirety. However, subsoils that have superior soil reconstruction and plant growth characteristics will be preferentially salvaged over inferior quality topsoil. Suitable subsoil materials may be used to make up short-falls in topsoil-poor areas. Site specific judgment, in combination with NRCS ratings (Table 2) will be used to detemrine whether or not a particular soil material will be salvaged for reconstruction purposes. The best suitable soil reconstruction materials available within the area to be disturbed will be identified and scheduled for salvage. Soil salvage will be performed using equipment best suited for the volume of material to be handled and the physical characteristics of the disturbance area. Handling of soil materials will be minimized in an effort to reduce impacts on soil structure. Bulldozers, loaders, haul trucks and scrapers may be used in soil salvage operations. To avoid unnecessary compaction, ingress and egress from the soil salvage area will, to the extent possible, avoid routes over surface areas where materials have not yet been salvaged. To avoid unnecessary damage to soil structure, handling of soil will be avoided or minimized, especially when soils are saturated with water or when they are excessively dry. Salvage operations will not be performed on slopes that are steeper than 2h:ly due to the poor quality of soil materials on such slopes, equipment limitations and personnel safety considerations. Topsoil on steep slopes generally lacks or has poorly developed ahorizons and A-horizons due to elevated erosion rates and poor soil-forming conditions. As a result, only small amounts of low-value soil resources will be sacrificed by not salvaging soils from steep slopes. When salvaged soils require storage prior to respreading, they will be placed in designated stockpile locations as near as possible to excavation locations. Stockpiles will be located on stable sites where wind and water erosion potentials are minimized. Stockpile areas will avoid or be adequately protected from concentrated surface flows. Stockpiles will be located in areas that are not planned to be disturbed by future operations. Soil will be selectively stockpiled according to material type (i.e., range site type and horizon). Temporary vegetative cover will be established on stockpiles as soon as possible when they ' become temporarily inactive. Stockpiles will be considered inactive when they are to be left undisturbed for a period of 12 or more consecutive months. When temporary revegetation is required, stockpiles will be seeded during the next normal planting periods (i.e., during the fall ' or early spring). The stabilization seed mixture to be used for establishing vegetation cover on stockpiles is provided in Table 3. This seed mixture will be applied at an approximate rate of 4.5 bulk pounds per acre.
