• area as shown on Map 5 (Existing Topography). Topsoil quantities stored in the <br />respective areas were as follows: <br />#1 - 6,000 cubic yards <br />N2 - 16,300 cubic yards <br />N3 - 7,400 cubic yards <br />~4 - 2,600 cubic yards <br />#5 - 400 cubic yards <br />p6 - 47,000 cubic yards <br />Total - 79,700 cubic yards <br />Topsoil stockpiles were not moved until required for distribution on <br />regraded areas. Topsoil was distributed as per the grading plan at depths and <br />with nutrients as outlined in the revegetation plan (Section 2.05.4). <br />While the haul road was being decommissioned, the lower Yampa River sedi- <br />mentation pond was reclaimed and replacement structure was constructed in accor- <br />• dance with CMLRD approved plan (Minor Revision 03). Prior to removing and <br />reclaiming the Yampa River structure, water was decanted, coal fines removed, <br />and soil samples obtained. Coal fines were disposed in the designated area <br />illustrated on Map 8. <br />Three representative sediment samples were analyzed to determine whether <br />the material in the impoundment would be detrimental in establishing a success- <br />ful revegetation program. Samples (Table 2.05.3-9) were analyzed by Accu-labs <br />Research for soluble cations, trace metals, and texture. Based on the analysis, <br />no chemical or physical constraints were identified; and after CMLRD review, the <br />material was used to reclaim the Yampa impoundment structure. The structure was <br />graded, topsoiled, mulched, fertilized, and seeded using the procedures outlined <br />in Section 2.05.4, and a diversion ditch was constructed as designed. <br /> <br />- 194 - (Rev. 5/86) <br />
