monitoring activities. Existing avenues of communication and cooperation between BME and federal/state agencies is considered adequate for the continued protection of this species. Reclamation will be started as soon as the refuse is brought to final grade in the area being worked. The layout of the Refuse Disposal Area is indicated on Map 76. The sub-areas that are already constructed or are in use are shown in greater detail on Map 77, Map 77A and Map 150. Additionally, two temporary storage areas will be utilized. Area #1 (Map 25) will be used for rotary breaker rock refuse storage pile and Area #2 (Map 26 & 27) for coal and/or coal refuse. Area #1 will contain a maximum of 8,000 tons of material at any on time. Quantities of material stored in Area#2 are limited to that shown in Section IV.C.4. Prior to actual disposal in the refuse disposal areas, an access road from the haul road will be constructed to the lower portion of the areas and the sedimentation ponds and lower parts of the diversion ditches will be placed. Topsoil from the pond areas will be placed in the topsoil storage pile and all fill material not required for embankment construction will be placed in the nontoxic fill storage pile. Trees and brush will be removed and the topsoil will be stripped and placed in the topsoil storage pile or on a refuse area being reclaimed. The topsoil storage pile will be mulched and seeded. After the topsoil is removed, enough nontoxic fill to meet the minimum cover depth requirement of 30 inches (as per DRMS's approval) will be removed and placed in the nontoxic fill storage pile or on a refuse area being reclaimed. BME will document topsoil/cover soil material balance as future refuse area development and reclamation progresses. The nontoxic storage piles will be stabilized and seeded to minimize erosion. The nontoxic fill in the storage pile will normally be used for reclamation of the sub-area where removed, but may be utilized on another sub-area if preceding area has been reclaimed during construction of a subsequent sub-area or to help balance excess and deficient subsoil quantities between piles. The topsoil thickness versus area information is given in Appendix IVA. To minimize the area occupied by the topsoil and nontoxic fill (subsoil) stockpiles the face slopes were set at 3h:1v and 2h:1v, respectively. Since these are relatively steep slopes, the faces of both stockpiles will be roughened or furrowed on the contour prior to reseeding. A sediment ditch is constructed around the base of both topsoil and subsoil stockpiles. An earthen berm with a rock filter at the low point is installed at the toe of the subsoil pile to drain the runoff collected from precipitation events. The ditches are cleaned as required to maintain their required cross section. See Maps 77. The procedure followed for Sub-areas RP-1, 2/3 and 4 was repeated for Sub-area 5A. Light utility roads were constructed along the west and east sides of Refuse Area 4 and 5 in order to maintain lights on the power lines. A dozer access crossing was constructed between RP-4 and RP-5A. TR-74 (4/2022) IV-17
