Specifications include, but are not limited to: remove the erosive material adjacent to the home and install a combination rock ditch-drain that connects to a rock ditch to the north and west of the home and a combination rock ditch-drain to the east of the home. Both ditches, which will collect both surface and sub-surface water, will outlet in natural drains. AMD is present at the site from multiple seeps. Drainage will be collected by a means of subdrains modified for AMD conditions (non-calcareous backfill and PVC pipe). In addition to the ditches and subdrains, a temporary debris barrier will be erected during construction and removed at the conclusion. All excavated material will be transported to, placed and revegetated at an approved waste area on Ligon Camp Branch located at latitude: 37 21' 43.2"N, longitude: 82 40' 6.88"W. Any woody materials requiring removal from the waste area will be burned or otherwise suitably disposed of. This project will not address underground mine openings. No trees are intended to be removed. All areas disturbed by this project will be revegetated by conventional seeding practices and/or hydroseeding according to standard details and technical specifications. Sediment control will be provided by silt fence/bales or other approved methods.
