Measurement and Payment There will be no measurement for payment. Payment for this task will be reflected in a lump sum bid under Item 2 on the Bid Schedule. This lump sum bid will cover all costs for construction of the drainage ditch protective berm, topsoil removal where necessary, excavation of coal refuse from the Old Refuse Pile, fill as required at the Old Refuse Pile, transportation and disposal of coal refuse at the designated disposal facility near the Wash Plant, creation of the design slopes at the Old Refuse Pile and at the disposal facility and dust control activities. Such payment shall be considered full compensation for all labor, materials, equipment and all other items necessary and incidental to the completion of Task 2, Earth Work, as directed and described in the specifications. Payment shall be as this task is completed and approved by the PROJECT MANAGER. TASK 3 TOPSOIL PLACEMENT Upon completion and approval of excavation activities by the PROJECT MANAGER, topsoil will be applied to the reconstructed north facing slope of the Old Refuse Pile which was created during performance of Task 2, Earth Work. Topsoil will be derived from that material stockpiled during performance of Task 2, Earth Work, and from an existing topsoil stockpile (Map 3, Project Area). The approximate distance from the west end of the Old Refuse Pile Project Area to the topsoil stockpile is 3,900 feet. It is estimated that 8,550 cubic yards of topsoil will be needed to achieve an average six inch (6") cover of material over the face of the north slope. This material will be derived primarily from the topsoil stockpile to be removed to the project site. Any additional volume necessary will be derived from other sources located approximately the same distance from the Old Refuse Pile as the designated topsoil stockpile. Upon completion of excavation of the topsoil from the stockpile, the ground surface under the stockpile is to be graded and shaped so that the foot print of the stockpile and any adjacent areas disturbed during performance of this contract blends with surrounding, adjacent topography. The ground surface shall be left in a roughened condition. No slope will be steeper than 2.5HAV, and positive drainage to the south will be accomplished, however, concentration of water in gullies or ditches is not acceptable. The stockpile and any adjacent disturbances created during performance of this Task will be revegetated as specified in Task 4, Revegetation. Topsoil will be spread to a depth of six inches (6") over the entire area affected by operations conducted on the north slope of the Old Refuse Pile during performance of Task 2, Earth Work. Upon completion of the topsoil application, the surface of the soil shall be left in a roughened condition. The CONTRACTOR will create a minimum of fifteen (15) small bumps or hummocks per acre on the slope. These features will be constructed in a random pattern across the slope. These bumps or hummocks will be the width of a dozer blade by six to eight inches (6" to 8") in height. The axis of these features will be constructed perpendicular to the fall of the slope. 11
