The Smokey Mountain Smelters site is located in Knox County, Tennessee. The area is the location of former fertilizer and smelting operations. EPA placed the site on the Superfund program�s National Priorities List (NPL) in 2010 because of contaminated soils, sediment and surface water resulting from past industrial operations at the site. EPA and the Tennessee Department of Environment and Conservation (TDEC) have investigated site conditions and taken steps to clean up the site in order to protect people and the environment from contamination. In 2008, EPA repaired the fence surrounding the site. In 2010, EPA demolished vacant on-site buildings. In 2011, EPA removed a portion of on-site waste and capped the rest. EPA continues to stabilize the top layer of the cap with grass. EPA and TDEC continue to monitor site conditions and investigate whether contamination on site could potentially threaten people living and working near the site. Once this investigation is completed, EPA will issue a cleanup plan (a Record of Decision, or ROD) to address all remaining contamination. EPA continues to update residents about the site by issuing fact sheets and related information about the progress of the site investigation.
