Specifications include, but are not limited to: The Willie Chapman AMD Abatement Project is located on Sunshine Lane near Phelps, Kentucky, N37 30' 49.0", W82 22' 41.8", and includes approximately 6.0 acres of total disturbance. Work proposed under this project will abate the impacts of acidity upon the Stinking Creek drainage created by AMD flowing from four abandoned mine openings (two open and two collapsed) and a seepage zone that is lubricating a landslide upon the Chapman property, and address health and safety issues posed by the two open draining portals plus one other abandoned mine opening within the hollow, and will also result in the removal of the landslide mass being lubricated by the AMD seepage zone discussed above, as accessing the portals and hollow drain requires addressing the landslide. The landslide, which threatens to damage or destroy two barns/storage buildings, to dam an unnamed tributary to Stinking Branch, and block access to the property and natural gas collection wells and structures, will be completely excavated. Encroachment by the landslide has already forced shifting of the stream channel that has partially undermined the larger of two barns located on the valley floor. The material excavated from the landslide, along with spoils from the construction of subdrains and other drainage control structures, will be taken to an Excess Earth Fill Area in nearby Deskins Branch, upon the site of a Title V coal mining operation. After removal of the landslide allows access to the remainder of the project area, three extant abandoned underground mine openings will be closed through installation of bat-friendly wildlife-accessible mine closures. Two of these mine openings emit drainage, and will have non-erosive flow paths established between the closures and the unnamed tributary. An existing eroded flow path adjacent to the third extant opening will be lined with a nonerosive material. The two collapsed mine entries, both of which show evidence of drainage flow, will be reopened for the installation of drainage structures and properly sealed. Non-erosive flow paths will also be established between these closures and the stream.
