z-24 <br />Investigation of possible sites along East Salt Creek drainage <br />• yielded a preponderance of narrow canyons. The following para- <br />graphs detail site selection, design and construction techniques <br />used by Salt Creek Mining Company to evaluate refuse disposal. <br />2.4.2.1 Refuse Area Location <br />To aid in site selection, Salt Creek Mining Company developed <br />guidelines to evaluate prospective areas. These guidelines were: <br />1) Limit conflict with agricultural resources. <br />2) Limit the amount of vegetation disturbed. <br />3) Keep all refuse out of East Salt Creek's valley <br />bottom. <br />4) No fill which completely blocks a natural drainage. <br />5) Maximize north facing slopes to enhance revegetation. <br />6) Limited visibility from State Highway 139. <br />7) Reclamation contours must blend into the surrounding <br />terrain and be compatible with intended final land <br />• use. <br />8) Minimize potential for disruption of hydrologic balance. <br />Using these limitations, selection of a site was narrowed to two <br />canyons on the east side of East Salt Creek. Further investiga- <br />tions into these two canyons showed that one had a large drainage <br />area, while the other had a relatively small drainage area. <br />The choice of areas was made based upon less diversion of a natural <br />ephemeral channel. The canyon chosen is shown on Figure 1.1-25. <br />General boundaries of the refuse area which complied with Salt <br />Creek Mining Company's guidelines were then established as noted <br />below: <br />1) The north flank of the pile must leave room to <br />relocate the ephemeral channel in the bottom <br />• to the north. <br />
