To clean up the Gallatin Fossil Plant and provide space for future coal combustion residual hauling and ash disposal, Barnard is working with the Tennessee Valley Authority to construct a new landfill.

As part of an effort to clean the Tennessee Valley Authority Gallatin’s Fossil Plant located in Sumner County, Tennessee, Barnard is constructing a new landfill to provide space for future coal combustion residual (CCR) hauling and final disposal of ash. The project includes the construction of Cells 4 and 5, which span across 32.2 acres and 34.9 acres of lined landfill, respectively. Additionally, Barnard is constructing new sediment basins and a contaminated stormwater basin, which require 235,000 CY of rock excavation and over 1.5 million CY of earthworks. Other work includes the construction of HDPE piping systems (17,500 LF of leachate pipe and 5,400 LF of contaminated stormwater pipe), installation of 25,800 LF of 25kV cable, excavation work by blasting, development, and maintenance of an onsite borrow, site electrical works, demolition of an existing conference center, and perimeter haul road construction.
