sediment traps will be installed where needed and appropriate. Inspection and maintenance of <br />erosion and sediment control structures will be performed on a regular basis and following <br />substantial runoff events to identify and correct problem areas. <br />E -4 SOIL INVENTORY, SALVAGE, AND STORAGE <br />Soil series to be disturbed and their characteristics are presented in Tables 1 -1 and 1 -2 in Exhibit I. <br />Soils in the project area are typically poorly developed due to low available moisture, cool <br />temperatures, and slow vegetative growth. The majority of the soils to be disturbed are well drained <br />with low to moderate water holding capacities. A number of the soils have a high percentage of <br />rock fragments while some are moderately to highly susceptible to erosion. It is understood that <br />salvaging and maintaining sufficient amounts of the best - suited soil reconstruction materials are key <br />elements to site stabilization, successful reclamation, and subsequent bond release. <br />Prior to disturbance, the perimeter of the areas to be disturbed will be visibly marked using <br />appropriate means. Salvage operations and other surface disturbing activities will remain inside the <br />marked area. If differential handling of soil materials is to occur, interior areas requiring such <br />handling will be clearly marked. <br />Any woody vegetation within the area to be disturbed that has the potential to interfere with soil <br />salvage, storage, or reconstruction will be physically removed. The smaller limbs of trees (under <br />four inches in diameter) will be scattered over non - disturbed areas, used for erosion control, or piled <br />into small piles for wildlife cover. Root systems will be left in place where feasible, as long as they <br />do not pose a safety concern for workers or an impediment to facilities or vehicles. Larger limbs <br />and tree trunks will be removed from the area and put to a beneficial use, if possible. Brush may be <br />cut or bladed from the surface and used for erosion control. <br />Soil salvage operations will be conducted in a manner that maximizes recovery of suitable <br />resources for soil reconstruction and minimizes handling. Where suitable soil is available, it will be <br />salvaged to a minimum depth of six inches or to the bottom of the A- horizon, whichever is greater. <br />Whenever possible, suitable A- horizons will be salvaged, handled, and stored separately from <br />subsoil materials. Complete salvage of the A- horizon will be performed since it serves as a <br />reservoir for important macronutrients and micronutrients essential for proper plant growth and <br />development. Organic material accumulations in the A- horizon also serve to promote plant growth <br />through better nutrient retention and better moisture availability. <br />G:LLM M78545.002\Redamation Redamexh.DOC <br />E-4 <br />
