of the gully from crest to crest. Rocks large enough to fill the <br /> trench will be placed within the trench to act as a foundation. <br /> Smaller rock will be stacked on and against the foundation rocl , <br /> filling the gully from side to side, to an average height and widt'fi <br /> of two feet. <br /> Another technique which will be used is to construct sediment <br /> control structures built from logs. Corps Members will fell nearby <br /> aspen trees and choke the gullies with the trees. To do this, a <br /> trench approximately eighteen inches wide and nine inches deep will <br /> be hand dug perpendicular to the orientation of the gully from <br /> crest to crest. Logs will be cut so that they fit inside t$e <br /> trench, and from side to side within the gully. Logs will be cut <br /> and placed within the gully in a pyramidal shape to a height of <br /> about two feet and a basal width of at least three feet. The <br /> branches and limbs will be cut and placed upstream of the log dam. <br /> In areas where there is sufficient subsurface water occurring <br /> within a gully, live transplanting of indigenous shrubs will take, ., <br /> place. Areas suitable for live transplanting will be identified by <br /> the Project Manger. Crew Members will cut shrubs, such as willows, <br /> to a specified length. The cuttings will be soaked in a nearby <br /> water source for a week, and then be transplanted into trenches <br /> hand dug by the Crew. The trenches will generally be constructed <br /> perpendicular to the gully length, and be nine inches wide by nine <br /> inches deep. the cuttings will be placed in the trenches, and the" <br /> trenches will then be backfilled by shovel and compacted by foot. <br /> It is estimated that construction of the sediment control <br /> structures will require one week of Crew time. <br /> Successful completion of the proposed project is dependent upon <br /> team work and interpersonal cooperation. For example, while some <br /> team members are planting trees, other crew members will be,/ <br /> preparing the trees for planting, or perhaps installing the sun <br /> shades. Certain efficiencies are gained by splitting the planting <br /> effort into two or three sub-tasks so that the overall project <br /> goals are accomplished by all. <br /> Accomplishment of the tasks involved in the proposed project are <br /> directly tied to the statutory mission of the Division, and to the <br /> site specific reclamation goals identified to be accomplished at <br /> Coal Basin. The Division is statutorily charged with protection of <br /> the hydrologic balance in and near coal mining operations. <br /> Sediment generation as a result of mining related erosion has been <br /> identified as a contributory factor regarding water quality <br /> concerns within Coal Basin. Completion of the project will <br /> directly impact the erosional processes in the Basin, thus helping ' <br /> to reduce the impacts to local water quality as a result of mining <br /> related activities. <br /> 5 <br />
