Superfund Site Profile
The 22,357-acre Milan Army Ammunition Plant (MLAAP) opened in 1942 for wartime munitions production. That work has recently moved to standby, but could restart if needed. Today, MLAAP has two primary military missions: 1) storage of munitions; and 2) support for U.S. Army (Army) National Guard and Reserve units for staging equipment and training. Following many years of munitions production and due to the discovery of munitions-related contamination in soil and groundwater, EPA placed the site on the Superfund program’s National Priorities List (NPL) in 1987.
Working together, the EPA, the Tennessee Department of Environment and Conservation (TDEC), and the Army have investigated MLAAP soils and groundwater and have taken action to protect workers, local residents and the environment. Currently, site contamination does not threaten people living and working at or near the site. By extracting and treating contaminated groundwater, capping and containing contaminated soil, conducting groundwater monitoring, and performing required Superfund regulatory Five-Year Reviews, EPA, TDEC and the Army continue to protect people and the environment from site contamination.
