Specifications include, but are not limited to: The proposed Alexander Scott Drainage AML Reclamation Project, approximately 0.5 acres total, consists of removing a failing 72 inch diameter corrugated metal pipe in a fill area created in 1993 by the 9AG Combs Branch AML project. This failure has caused large and dangerous sinkholes to develop in the fill that pose a hazard to the public. The old pipe will be replaced with twin 60 inch HDPE pipes and headwalls. The project is in Gregory Branch in Perry County. The site is located in the Hazard South Quadrangle. The Alexander Scott site is at 37 14 ' 10.45" N, 83 10 ' 7.59" W. To reach the site from Bulldog Lane at the AML office turn right onto KY route 15 and travel south for 2 miles. At the traffic light turn left onto the bridge. At the end of the Bridge turn left onto Christopher Road (KY RT. 451) continue for 1 mile and turn right onto Gregory Branch Road. The project area is about 500 feet on the left across from the gabion and concrete retaining walls. No waste area is needed for the project, however the old pipe is to be properly disposed of at a landfill. The Project will entail the removal and disposal of 160 L.F. of failing 72" CMP, and its disposal in a landfill. Twin 60" HDPE pipes 200 linear feet with concrete headwalls will be installed to convey the waters of Gregory Branch. All eroded and unstable slopes will be graded and stabilized. Erosion control blanket will be used to protect critical areas. Fencing will be placed at the top of the headwalls to discourage use by the public. The project site has previously been disturbed by coal mining operations, house seat development, utility installation, road construction, and/or landowner activities. These disturbances consist of significant upheaval, mixing, and removal of earthen material from deep excavation, grading, sub-surface drilling, fill material placement, and erosion. There should be no undisturbed earthen material to a depth of several feet at the areas slated for significant project-related construction activities. Construction disturbances will be kept to a minimum with a stringently formulated sediment and erosion control program. Prior to beginning any major earth disturbance (excluding initial site preparation for access only), all silt control measures will be installed. The silt barriers (bales & silt fence) at the project site. No trees greater than 3" diameter at breast height will be cut outside the unstable and eroding areas. All disturbed areas will be promptly revegetated at the end of construction using lime, fertilizer, residential or wildlife seed, and mulch, as necessary. Standard measures will be used for dust control and work hours will occur during AML's standard time frame of 7 am to 7 pm Monday-Friday with shorter hours for "critical" work items. Access to the site is via county roads, residential driveways and yards, and an existing access road. This project will include pre- and/or post- project maintenance and repair of existing previously constructed public county roads utilized during the construction of this project, which are administered by the county or local road authority. This construction activity will be conducted under the authority and supervision of the local public road authority and will consist of standard road construction practices appropriate to mitigate impacts to the local community from potential degraded road conditions in order to maintain public traffic safety.
