t4INING REPORT <br />Goal <br />The purpose of this project is to level and regrade agricultural <br />land by excavating sand and gravel. The project site contains <br />approximately 149 acres of which approximately 52.4 acres may be <br />excavated. Gravel extraction will consist of relocating the gravel <br />terrace face to conform with existing irrigation ditches. Gravel <br />faces will be left at 2:1 or 3:1 slopes. The excavated land will <br />be graded to an approximate .5~ slope. Grading will eliminate water <br />entrapment areas. The leveling and gracing process will result <br />in creation of agricultural land which can better utilize irrigation <br />flows and groundwater. A lake will also be created. Excavated <br />land to be revegetated for pasture will be topsoiled to a depth of <br />4 to 8 inches. <br />General Description of Operation <br />The sand and gravel deposit at the proposed Chambers Pit may pro- <br />vide construction material for 11 to 28 years depending on market <br />conditions. Two areas will be mined concurrently, with activity at <br />Area A being limited to times when winds are minimal and when soil <br />moisture content is sufficient to result in good dust control. <br />The areas to be excavated are parts of a terrace above the Eagle <br />River. The sand and gravel deposit rises to approximately 30 <br />feet above the valley. The terrace face slopes at approximately 2:1 <br />and supports sparse vegetation including a scattering of trees. <br />Distance from the terrace excavation to the river varies, being <br />closest at the western mining area (B), where its usual distance <br />D-1 <br />
