<br />have adequate and even abundant quantities of soils. The operator will need to use semi- <br />selective salvage methods because it is vital that all available soil be carefully salvaged. The <br />clay deposits are inappropriate as a growth medium. It is unlikely that residual clays would <br />support any kind of suitable growth even if they were chemically treated. <br />A soil salvage recommendation table appears in Exhibit I. The recommendations will be <br />followed closely, particulazly with respect to soils that may or may not be salvageable. All of the <br />salvageable soils have an excellent differentiation between horizons. They will be relatively <br />easy to salvage. The darker topsoil material can be sepazated from materials in the lower <br />horizons which may be quite light in color and usually much more sandy to gravelly. <br />It appears from the survey that an average of about eight inches of topsoil is salvageable <br />in selected soil units. In low lying areas this value may increase to between 12 and 24 inches, <br />but upland areas may have as little as four inches of topsoil. About four inches of subsoil can be <br />added to this value; some subsoil will be stripped with the topsoil simply because equipment <br />cannot operate with such precision as to eliminate all subsoil from the topsoil salvage. <br />Therefore, an average depth of about 12 inches should be obtained from most azeas. Most of the <br />Louviers cobbly clay loam will be discazded due to its extremely low quality. <br />Salvageable soils occur in about 60-70% of the total permit area that could be affected. <br />Of the remaining 30-40% occupied by soils of questionable value, it is estimated that about 30% <br />could be salvaged. This raises the total salvageable percentage to about 75%. From this 75% <br />must be acquired the soil for 100% of the area. If the average salvage depth is 12 inches, then <br />the average redistribution depth will be 75% of the salvage depth, or about eight inches. <br />Therefore, a thickness averaging six to ten inches of soil will be spread on areas to be <br />revegetated. <br />Draft Revision July 1999 <br />8 <br />
