Site DescriptionThe Joliet Army Ammunition Plant Manufacturing (MFG) Area located in Will County, Illinois, covers 14 square miles of an inactive Army munitions facility. The site, which is adjacent to the Load-Assembly-Package (LAP) Area [another National Priorities List (NPL) site], is 10 miles south of Joliet, Illinois. Together the two sites constitute the JOAAP NPL Facility. From the early 1940s through 1977 more than 4 billion pounds of explosives, primarily trinitrotoluene (TNT) and tetryl, were made in the MFG Area. The production facilities were located in the northern half of the MFG Area. The southern half of the MFG Area was occupied by extensive explosives storage facilities.
The MFG Area included:
- the explosives manufacturing lines;
- the TNT ditch complex, where process wash and waste waters were discharged or transported for treatment;
- the Red Water Area consisting of storage tanks, incinerators, evaporators, and a lined lagoon;
- incinerator ash piles;
- the Flashing Grounds, used for flash burning material to remove explosive residues;
- an area formerly used for the production of lead azide.
Approximately 1,200 people live within three miles of the site. The nearest residence is less than one mile away, and there are water supply wells in use within a one-mile radius of the site. The surrounding area is primarily used for agriculture, and a substantial amount of farming and grazing is carried out on uncontaminated portions of the installation.
Site ResponsibilityThis site is being addressed through federal actions. The U.S. Army has the lead responsibility at the site.
Threats and ContaminantsThe area contained 139,500 cubic yards of soil, contaminated with explosives, primarily TNT, tetryl, and dinitrotoluene (DNT). There were also 13,500 cubic yards of soil, contaminated with metals, primarily lead, and 15,700 cubic yards of soil, contaminated with explosives and metals. There are two landfills, covering approximately 90 acres; two large ash piles, covering approximately 15 acres; and a number of onsite groundwater plumes, contaminated with explosives, volatile organic compounds, and/or metals.
Cleanup ProgressDuring 1996, the Army, using Superfund removal authorities, removed more than 1,200 electrical switch boxes that were filled with oil and were potential sources of contamination. They also placed a membrane cover over an eight-acre ash pile in order to control leaching from the pile.
A Record of Decision (ROD) was signed for the entire Joliet Army Ammunition Plant in November 1998. The ROD presented both final and interim response actions for contaminated soils and final actions for contaminated groundwater. Final actions for the MFG Area included: excavation and onsite bioremediation for explosives-contaminated soil; excavation and onsite or offsite treatment for other contaminated soil; excavation and offsite disposal of the two ash piles; capping the two landfills; and natural attenuation with deed restrictions for the groundwater plumes.
Final remedial alternatives for the interim component of the soil remedy were developed and presented in a proposed plan. A final ROD was signed in September 2004. Final site cleanup has been completed, as documented in the site Preliminary Close Out Report, which was completed in September 2008.
Composting was chosen to bioremediate explosives-contaminated soil. The bioremediation facility was built in fall 1999. T he 20-acre bioremediation facility consisted of three 25,200-square foot treatment buildings, each housing two concurrent windrows or elongated piles; an 80,000 cubic yard stockpile area; and a one-million gallon stormwater basin.
Excavation of explosives-contaminated soil began in July 1999. Ultimately, a total of 205,000 cubic yards of contaminated soil were successfully bioremediated, with the project completed in 2007.
In December 2005 excavation of one of the ash landfills began. By March 2006 the landfill was completed excavated and over 55,000 cubic yards of material were excavated and sent to the Will County landfill for disposal. In May 2006 excavation began at the remaining ash landfill. Removal of the landfill materials was completed in the spring of 2007.
The first basewide Five-Year Reviw was completed in May 2004 and the second in September 2009. Per the 2009 Five-Year Review, the remedies that have been implemented at the JOAAP Site are considered protective of human health and the environment in the short term. They will be considered protective in the long term once all necessary institutional controls have been implemented and/or documented.
In September 2011, U.S. EPA determined that the JOAAP Site(s) are Sitewide Ready for Anticipated Use (SWRAU)
The U.S. Army has developed and implemented a long-term groundwater monitoring program for JOAAP. A followup Munitions and Explosvies of Concern (MEC) investigation at Landfills 2 and 3. The investigation will focus on the extended buffer area around the two landfills. Plans have been approved and field work is expected to begin in November 2011.
Finally, the U.S. Army has contracted for the development of a Deed Restrictions Work Plan, the purpose of which will be to effectively monitor land use controls in the form of deed restrictions on an annual basis.
Success StoryThe former Joliet Army Ammunition Plant (JOAAP) - one of the largest and most productive ordnance complexes ever built, has a new identity as the Midewin Tallgrass Prairie, Abraham Lincoln National Cemetery, Prairie View Landfill, and several state-of-the-art manufacturing and distribution business parks. After extensive environmental investigation and cleanup, and close collaboration between federal, state, and local governments, community groups, and the private section, the cleanup of JOAAP was completed in early 2008 - three years ahead of schedule.
Community InvolvementThe Restoration Advisory Board, involved at the Joliet Army Ammunition Plant for over 10 years, represents the community's interests in the environmental cleanup to the Army and other government agencies.
Congressional InterestBoth former Congressman Sangmeister and Congressman Weller have worked with stakeholders in developing and implementing a balanced reuse plan for the Joliet Army Ammunition Plant.
Future land use at the Joliet Army Ammunition Plan is prescribed in the Illinois Land Conservation Act of 1995. The MFG Area is designated to become a portion of a Midewin National Tallgrass Prairie, a national veterans cemetery, and an industrial park.
The first transfer of JOAAP land was completed in 1997 when 15,089 acres of land that did not require cleanup were transferred to the auspices of the U.S. Department of Agriculture/Forest Service for the creation of what will eventually be the 19,000 acre Midewin National Tallgrass Prairie. In September 2005 an additional 2,600 acres were transferred for incorporation into the prairie.
In August 2000, the Army transferred 1,300 acres to the State of Illinois for development of an industrial park. The propery was subsequently transferred to CenterPoint Properties to build the $2 to $3 billion Deer Run Industrial Park, with an intermodal rail facility and 17 million square feet for light industry. Construction of the industrial park, estimated to take 10 to 12 years, began immediately. CenterPoint estimates the project could generate approximately 20,000 construction jobs and 8,000 permanent jobs upon completion. The intermodal rail yard opened in October 2002. An additional 218 acres were transferred for the industrial park in 2001 after being cleaned up by the Army. An additional 13 acres were transferred for the industrial park in August 2003. Additionally, 982 acres of the former JOAAP were transferred to the Department of Veterans Affairs and developed as the Abraham Lincoln National Cemetary. The cemetary, which will provide 400,000 burial spaces, was dedicated in1999. In April 2002, the Army transferred 455 acres to Will County for the establishment of a municipal landfill, which opened in January 2004.
