cover are effectively controlling erosion in this area. Evidence of off-site sedimentation <br /> has not been observed. <br /> West of Road A Construction Area <br /> Final reclamation of this area was accomplished in 1999. Again, multiple Best <br /> Management Practices were implemented in the West of Road A Area, including severe <br /> surface roughening, construction of small ridges built perpendicular to the fall of the <br /> small hill slope at the southern portion of the area, silt fence placement and the use of <br /> weed free straw bales. No problems or maintenance needs were observed in this area <br /> following multiple inspections. Vegetative cover was measured to be 61% in the late <br /> summer of 2005, well exceeding the estimated pre-reclamation cover of less than 5%. <br /> The landform and vegetative cover are sufficient to control erosion at this area. Evidence <br /> of off-site sedimentation has not been observed. <br /> Termination Criteria <br /> All termination criteria have been met at the Lower Coal Basin Reclamation Construction <br /> Projects Stormwater Permit area. <br /> - All raw materials, intermediate products, in this case washed coal refuse, finished <br /> products and waste products have either been removed from the site, or have been <br /> isolated from stormwater as a result of the reclamation process. All coal refuse <br /> has been removed to the coal refuse disposal areas. The refuse within the disposal <br /> areas is isolated from stormwater, and are covered by topsoil. All of the <br /> reclaimed areas have been graded to achieve geomorphically stable landforms that <br /> do not display evidence of erosion or off site sediment contribution. <br /> - All soil-disturbing activities have been completed. No further reclamation work <br /> is planned or anticipated within the stormwater permit area. <br /> - Vegetative cover within the stormwater permit area has been measured to <br /> significantly exceed 40%. The cover is sufficient in extent to minimize erosion <br /> potential and resultant sediment contribution to receiving streams. <br /> 4 <br />
