Site Status Summary <br /> Old Refuse Pile Project Area <br /> Huntsman Project <br /> The Huntsman Project Area is an approximately six acre area situated on the side slope of <br /> a much larger coal refuse disposal area, located just east of the newly constructed Dutch <br /> Creek stream channel. Reclamation of the Huntsman area was completed in 1997. Silt <br /> fence and dozer hummocks were the primary Best Management Practices employed in <br /> this area. The dozer hummocks were very effective in disrupting runoff patterns, and at <br /> containing sediment generated from the Project Area until vegetation became established. <br /> Due to the effectiveness of the vegetative cover at controlling erosion, the silt fence was <br /> removed from this area. The vegetative cover at the Huntsman Project Area was <br /> measured to be 89% in the late summer of 2005. This degree of vegetative cover, which <br /> exceeds the pre-reclamation vegetative cover by an estimated 74%, effectively minimizes <br /> erosion at the Project Area. <br /> Bear Creek Project <br /> The Bear Creek Project Area is situated on the side slope of a much larger coal refuse <br /> disposal area, and is located at the far easterly portion of the stormwater permit area, <br /> adjacent to the Huntsman Project Area. Reclamation at the Bear Creek Project Area was <br /> completed during the 1999 construction season. Approximately six acres of steep slopes <br /> were reclaimed during the course of this project. <br /> Multiple Best Management Practices were implemented in the Bear Creek Project Area, <br /> including the use of severe surface scarification prior to seeding, shrub planting, <br /> placement of slash barriers and the use of silt fence. <br /> The vegetative cover at this area was measured to be 77% in the late summer of 2005. A <br /> cattle exclosure was constructed around the area in 2001, resulting in significant <br /> vegetative establishment within the area over a short period of time. Grazing is now <br /> allowed in the area as part of a larger cattle management plan implemented by the U. S. <br /> Forest Service. Because the vegetative cover at the Project Area is effective at <br /> minimizing erosion, evidence of off-site sedimentation has not been observed. <br /> East of Road A Project Area <br /> Reclamation construction was completed in this area during 1999. This is a generally flat <br /> lying area that is bisected by the newly constructed Dutch Creek channel. Grazing of the <br /> area occurs as part of a larger cattle management plan implemented in Coal Basin by the <br /> U. S. Forest Service. Best Management Practices implemented during and following <br /> reclamation construction included the use of severe surface roughening,placement of silt <br /> fence, construction of small earthen berms and the placement of weed free straw bales. <br /> Vegetative cover in this area was measured to be 64% in the late summer of 2005, well <br /> exceeding the estimated pre-reclamation cover of 5%. The landform and vegetative <br /> 3 <br />
