Timber Ridge Landfill Closure

Modern landfills operate under many federal and state regulations. Under the U.S. Environtmental Protection Agency (EPA) Title V, landfills must prevent the escape of methane gas emissions through the installation of a Gas Collection and Control System (GCCS). In addition, EPA Subtitle D requires landfill operators to perform temporary or intermediate clo- sure once individual landfill cells are full and then install a “final cap” once a landfill has reached its maximum permitted capacity and cannot be expanded. In December 2010, Progressive Waste Solutions (formerly IESI-BFI Canada) installed a new synthetic closure system on nine acres (3.64 hectares) of their Timber Ridge Landfill in Richwoods, Mo.
