2-2s <br />2) The west end of the pile should leave room for <br />• sedimentation structures. <br />3) The east end is bounded by the valley slope. <br />4) The south side is bounded by the hilltop. <br />It was possible to meet all boundaries during construction of <br />Phases One and Two, but the volume of refuse to be disposed of <br />during Phases Three and Four was too large to be contained <br />within the boundaries preferred. <br />Rather than construct another refuse area, it was decided that <br />the refuse area would have to encroach upon the hilltop to the <br />south. Though more undisturbed area would be affected by this <br />measure, some of the refuse could also be placed on top of the <br />Phase Two design top, thereby lessening disturbance. <br />This design also had the advantage that the existing slope of <br />the land would now tend to drain water away from the refuse pile <br />• and limit post reclamation groundwater influx. <br />2.4.2.2 Design and Construction <br />Of primary importance in construction and design of any refuse <br />disposal area is minimizing detrimental effects upon the environ- <br />ment. Proper design and construction techniques coupled with a <br />good reclamation plan can minimize these effects. Salt Creek <br />Mining Company will meet this goal. . <br />Selection of the best available site to locate the refuse, as <br />detailed in the previous section, is the first step in minimizing <br />detrimental effects. Secondly, the refuse pile must be designed <br />and constructed properly. The volume and composition of refuse <br />is known and must be placed properly to form the pile. <br />The ie~u~dat~.on of Salt Creek Mining Company's refuse area will <br />first be stripped of topsoil. After topsoil is removed, the <br />• land will tend to channel any water towards the existing channel. <br />
