' EXHIBIT D (Cont'd) <br />' strata from three recent floods are readily observed. <br />The soils which are present will be segregated carefully <br />' and stockpiled on the setback areas and, if necessary a <br />hold cover of western wheatgrass will be used to minimize <br />wind and water erosion as well as deterioration of the <br />' soil. <br /> The water encountered when the overburden and part <br /> of the aggregate are removed will be used to float a <br /> boat containing a dredge. The dredge will have a ladder <br />1 f <br />ffi <br />l <br />i <br />h <br />ffi <br />i <br />i <br /> o <br />su <br />ent <br />engt <br />to be e <br />ently operated <br />n depths <br />c <br />c <br />' of water up to 55 feet, the maximum thickness encountered <br /> by core drilling.
