2- 51 <br />• 2.4.5 Erosion Control Considerations <br />2.4.5.1 Existing Erosion <br />Existing soil erosion rates in areas to be affected by the mine operation vary with the type <br />and shape of landform, soil characteristics and vegetative cover. Erosion potential exists for <br />three landforms within the area to be affected: <br />O Valley filling fan and sideslope deposits <br />O Steep sideslopes <br />O Valley floodplains <br />Soil loss rates were not calculated for each landform type; however, the presence of rills <br />and gullies in the area substantiates the fact that a significant amount of soil loss is realized <br />annually from the undisturbed slopes. Soil loss in the floodplain is negligible except for the <br />cutting of the unvegetated stream banks that continue to erode during periods of stream flow. <br />• 2.4.5.2 Anticipated Soil Erosion and Control Measures <br />Disturbed soil areas within facilities areas will be revegetated for aesthetics and erosion <br />control upon completion of construction, species utilized for vegetative cover will correspond to <br />species proposed in the reclamation plan for the speck land use type disturbed and reclaimed. <br />In addition, appropriate trees and shrubs will be planted to provide aesthetic appeal and blending <br />of facilities areas with the adjacent natural vegetation. <br />When rills and gullies deeper than 9 inches form in regraded areas that have no vegetative <br />cover, necessary measures will be taken to stabilize the site, and the area seeded or reseeded <br />as appropriate. <br />• <br />M~ Volume 1 4-29-96 <br />
