Estimated Length of Project:
(Substantial Completion) + 480 Calendar Days (Final Completion)
The 23067AMLBAML Reclamation Project will reclaim approximately 77 acres of areas
adversely affected by past coal mining operations.
The reclamation task of Stony Point AML Reclamation Project is divided into five (5)
earthwork areas with acidic refuse, mine spoil ridges, and mining impoundments. Work includes backfilling existing mine pits/silt ponds with adjacent mine spoils. All water below 6.0 pH shall be treated in strict accordance with KYAML technical specifications. A pump to dewater the pits is likely needed. A domestic & mining debris disposal bid item is included for removing and properly disposing of all items that qualify. Silt Fence and Silt Traps are included to control all sediment from the site during construction activities. Ditches lined with ECB and Class II and Class III channel lining are proposed to properly handle surface waters within the construction limits as designed. Likewise, 18-inch HDPE culverts are included to properly handle surface waters as designed. ECB Anchors will be installed as needed to secure in place erosion control blanket in proposed ditches and as a secondary silt control measure. Filter Fabric is included to use in aggregate ditches to increase stability and reduce sediment. Permanent Low Water Crossings are proposed for stream crossings in some areas. Revegetation efforts include Seed Bed Prep, Agricultural Limestone, Fertilizer, Seed, Mulch, and Crimping. Agricultural Limestone is also to be used as a barrier between acid and cover material. Limestone sand is included for ditches which are constructed over acidic materials and other areas as passive treatment where designated. Roadway Stone is setup to facilitate construction access and to maintain “in kind” existing gravel roads.
The entire project work area slated for any excavation has been previously disturbed by
coal mining operations, utility installation, road construction, residential development, and/or high velocity water flows associated with heavy rain events and flooding.
Construction disturbances will be kept to a minimum through the use of a stringently
formulated sediment and erosion control program. Hay bales & silt fence will be installed and maintained at all disturbed areas for silt control in accordance with AML’s Best Management Practices. All disturbed areas will be promptly revegetated using agricultural limestone, fertilizer, seed, and mulch, as needed.
