The agricultural land to the north is roughly 150' lower in elevation <br />so visibility of the operation will be minimal to none. <br />On the initial plant site, which is occupied by the Manuel soil, the <br />topsoil will be stripped prior to construction of the plant. This stripping <br />will be dme in accordance with the topsoil salvage plans to be discussed <br />later. tJien the plant is moved to within the mined area there will be no need <br />to strip soil as the soil will already have been removed during the mining. <br />TO'SOIL SALVA(~ PLAN: Salvage of the topsoil far use in reclamation is an <br />important operation that greatly controls the success of the reclamatim <br />plans. Salvage plans are designed around the expected soil structure. <br />Fbwever, the expected soil structures are somewhat idealized and variations <br />can be found on individual sites. Therefore, although the plans presented <br />here will be as closely followed as possible, sortie flexibility needs to be <br />• allowed the operator. If it is expected that 8" of topsoil should be removed <br />and there is only 6" of topsoil present on a particular location then removing <br />6" should be allowed. In those cases removing 8" could cause the inclusion of <br />undesirable subsoil components in the topsoil that could result in reduced <br />reclamation success. <br />lahere the Cascajo soil is present (identified by its high gravel <br />content) salvage will be to a depth of 3 to 6 inches or until the dark <br />material resting on tap of the light colored and intensely gravelly parent <br />material is encountered. In the old gravel pit area this 3 to 6 inch depth <br />would be appropriate over most of the site. But some local areas appear to <br />have only about 2 to 3 inches of organically dark material resting on tap of <br />the gravel. This variation is expected to occur in other areas. <br />On the Manuel soils (identified by a silty texture and usually located <br />below the elevation of the gravel layer) the topsoil will be stripped to a <br />depth of 5" to 7" where the plant site will be initially located and where <br />access roads are needed to cross land between various gravel deposits.
