Description
This case study involves review of the closure design and construction of a 250-acre gypsum stack at TVA's Paradise Fossil Plant using Watershed Geo's ClosureTurf final cap system. The design review will include the selection criteria of the final closure cap system, the use of a flatter-than-conventional 150-acre top deck grade, discussion of the storm water management strategy, and the planning for future use which potentially includes solar development and future harvesting of the CCP. Lessons learned will be presented including performance of the flat top deck, challenges associated with access roads over ClosureTurf, and geosynthetics documentation processes.
