Site work and paving for a civil project in Millstone, Kentucky. Completed plans call for site work for a bridge / tunnel; road / highway; for paving for a road / highway; and water / sewer project.

This project will create approximately 2.0 acres of disturbance within project boundaries encompassing approximately 9.0 acres. Reclamation actions under this project will include: Construction of a drainage ditch armored with concrete block tied mat (CBTM) to collect drainage from four collapsed mine entries and route it to a natural drainway Construction of a gabion silt-check to collect sediment and debris remaining in the steep hillside drainway following an apparent underground mine blowout that occurred in response to historically heavy rainfall near the end of July, 2022. A slotted 24" diameter HDPE standpipe will allow drainage to bypass the gabion check while sediments are collected. Installation of a 24" diameter culvert, with four drop-box/cleanout structures and a junction box along its length, and a concrete outlet headwall with CBTM splash-pad at its outlet to safely route drainage collected by the gabion silt-check past the Napier Residence to the existing roadside ditch. Cleanup of mudflow debris from around the Napier residence, which was deposited as a result of the underground mine blowout noted above. Construction of a 5' high concrete gravity wall to serve as a water deflector in the event of a future sudden discharge of water escaping the gabion silt-check Cleaning of the roadside ditch between the outlet of the new 24" HDPE pipe and the inlet of a highway culvert located approximately 260 feet ENE along KY-803. Excess earthen material not utilized on-site will be removed to a disjunct fill area located on the future location of the Mayking Volunteer Fire Department, located approximately 5.6 road miles from the project site. This project will not result in the direct disturbance of any streams. The strict implementation and enforcement of standard AML sediment and erosion control Best Management Practices (BMPs) will prevent significant amounts of sediments disturbed by project-related activities from entering area streams to create indirect impacts to aquatic resources. This project will not cause any impacts to caves or cave-like structures, specifically including underground mine workings. However, this project will require the disturbance or removal of trees measuring over 3" dbh during rehabilitation of an existing alternate access to the construction site, establishing access to the drainway behind the Napier residence, installation of the CBTM ditch, the outlet end of and headwall for the 24" culvert, and the excavation and grading required for installation of the gabion silt check, totaling approximately 0.5 acre of forest disturbance. The entire project site has previously been thoroughly disturbed by one or more of coal mining operations, residential construction, and highway construction.
