amm <br /> + o Transit Mix Concrete Co. <br /> Subsoil <br /> Subsoil made up of fines from plant losses and overburden removed during mining will be used <br /> as a plant growth medium between affected areas and the topsoil which include highwall benches, <br /> the pit floors, and the access road. During mining, overburden and fines generated will be direct <br /> hauled and placed as backfill in the pit areas as soon as practicable and as areas become <br /> available. At least one-foot of fines/overburden will be placed over the affected areas. These <br /> subsoils will be scarified to eliminate smooth surfaces to allow roots to penetrate. This will be <br /> done prior to placement of the topsoil to help reduce topsoil compaction (Brown &Hallman, 1984). <br /> Topsoil Application <br /> All available topsoil will be salvaged prior to disturbing an area, per Rule 3.1.9. After the affected <br /> areas have been regraded and the subsoil placed, topsoil will be placed. Topsoil will be applied <br /> on areas shown on Figure F-1. Topsoil removed during Phases I and II will be stockpiled in one <br /> of the designated stockpiles. Topsoil removed during Phases II through V will be used for <br /> contemporaneous reclamation as needed and excess material will be stored in topsoil stockpiles <br /> TS4. Topsoil stockpiled adjacent to the access road will be used for reclamation of the road <br /> corridor. The topsoil thickness will be a minimum of six inches. <br /> As noted above, highwall slopes will be stabilized but will not be topsoiled or revegetated. The <br /> highwall benches will be topsoiled and revegetated. Based on the NRCS data, a maximum of six <br /> inches of topsoil will be salvaged from any new affected lands. Topsoil will be redistributed at a <br /> minimum depth of six inches to match the native site conditions, as recommended by Quarry <br /> reclamation practices (Mineral Industry Research Organisation, 2004). Topsoil will be placed <br /> loosely to encourage greater species diversification and establishment (ARRI, 2007). Where <br /> practicable topsoil will be applied when soils are dry to help minimize compaction of the rooting <br /> zone (Vogel, 1987). Treatment such as ripping or scarification will be conducted to reduce <br /> potential slippage and to promote root penetration, further protecting such vegetation (Vogel, <br /> 1987). <br /> Seeding will occur within five days of spreading the topsoil. With time, some of the topsoil <br /> materials will migrate into the subgrade, enhance its ability to store moisture from precipitation, <br /> and enhance root development. Noxious weed management will be performed, in order to <br /> adequately protect developing vegetation, as discussed in the attached Noxious Weed <br /> Management Plan. <br /> Revegetation <br /> Affected areas will be revegetated in such a way as to encourage a diverse, effective and long <br /> lasting vegetative cover that is capable of self-regeneration without continued dependence on <br /> irrigation, soil amendments or fertilizer, and is at least equal in extent of cover to the natural <br /> Hitch Rack Ranch Quarry Permit Application <br /> March 20,2018 E-7 <br />
