• Map 76. The sub-areas that will be used until 2006 are shown in greater detail on Map 77, Map <br />77A and Map 150. <br />Additionally, two temporary storage areas will be utilized. Area #1 (Map 25) will be used for rotary <br />breaker rock refuse storage pile and Area #2 (Map 26 & 27) for coal and/or coal refuse. Area #1 <br />will contain a maximum of 8,000 tons of material at any on time. Quantities of material stored in <br />Area #2 are limited to that shown in Section IV.C.4. <br />Prior to actual disposal in the refuse disposal areas, an access road from the haul road will be <br />constructed to the lower portion of the areas and the sedimentation ponds and lower parts of the <br />diversion ditches will be placed. Topsoil from the pond areas will be placed in the topsoil storage <br />pile and all fill material not required for embankment construction will be placed in the nontoxic fill <br />storage pile. Trees and brush will be removed and the topsoil will be stripped and placed in the <br />topsoil storage pile or on a refuse area being reclaimed. The topsoil storage pile will be mulched <br />and seeded. After the topsoil is removed, enough nontoxic f II to meet the minimum cover depth <br />requirement of 30 inches (as per DMG's approval) will be removed and placed in the nontoxic fill <br />storage pile or on a refuse area being reclaimed. BME will document topsoil/cover soil material <br />balance as future refuse area development and reclamation progresses. <br />The nontoxic storage piles will be stabilized and seeded to minimize erosion. The nontoxic fill in the <br />• storage pile will normally be used for reclamation of the sub-area where removed, but may be <br />utilized on another sub-area if preceding area has been reclaimed during construction of a <br />subsequent sub-area or to help balance excess and deficient subsoil quantities between piles. The <br />topsoil thickness versus area information is given in Appendix IVA. <br />To minimize the area occupied by the topsoil and nontoxic fill (subsoil) stockpiles the face slopes <br />were set at 3h:1v and 2h:1v, respectively. Since these are relatively steep slopes, the faces of both <br />stockpiles will be roughened or furrowed on the contour prior to reseeding. <br />A sediment V-ditch is constructed around the base of both topsoil and subsoil stockpiles. An <br />earthen berm with a rock filter at the low point is installed at the toe of the subsoil pile to drain the <br />runoff collected from precipitation events. The ditches are cleaned as required to maintain their <br />required cross section. See Maps 77 and 83. <br />The procedure followed for Sub-areas RP-1, RP-2/3 and RP-4 was repeated for Sub-area 5A. <br />Light utility roads were constructed along the west and east sides of Refuse Area #4 and #5 in <br />order to maintain lights on the power lines. A dozer access crossing was constructed between RP4 <br />and RP5A. <br />The merging of RA-2/3 and RA-4 began during the summer and fall of 1998. <br />• Permit Rev. 4 (07/2002) IV-17 <br />
