  • To ensure the uninterrupted navigational operation of the Corps dam and associated facilities, the license requires project operation consistent with a new Memorandum of Agreement (MOA) between Appalachian and the Corps. The license requires the project to be operated in run-of-river mode and requires an operation and compliance monitoring plan to ensure that Appalachian meets these requirements.
  • To enhance the recreational user’s experience, the license requires Appalachian to develop and implement a recreation plan to include the addition of trash and restroom facilities at the tailrace fishing areas and to document maintenance and operation of the existing parking areas, paths, stairs, and tailrace fishing piers.
  • To minimize impacts on botanical resources and wildlife habitat, including potential habitat for species listed as threatened or endangered under the Endangered Species Act, this license requires Appalachian to develop and implement a vegetation maintenance plan to define the type, frequency, and extent of maintenance activities within the project boundary and to schedule maintenance activities to minimize impacts on terrestrial resources including potential habitat for federally listed plants and wildlife.
  • To protect birds from mortality due to electrocution and collision at project transmission lines, this license requires Appalachian to develop and implement an avian protection plan.
  • To protect cultural resources, the license requires Appalachian to prepare and implement an HPMP for the project.
