Addendum C: Chemical Demilitarization


Title 50, United States Code, section 1521 directs the Department of Defense to destroy the United States' chemical weapons stockpile. This statute also provides for the establishment of a management organization within the Department of the Army to carry out this mission. In addition, the United States is a state party to the Chemical Weapons Convention (CWC), an international treaty prohibiting development, production, stockpiling, and use of chemical weapons and requiring the destruction of existing stockpiles and demolition of chemical weapons production facilities.

The U.S. Army Chemical Materials Agency manages this nationally important and internationally significant program to safely store and destroy all U.S. chemical warfare materiel with joint oversight from the Assistant Secretary of the Army (Acquisition, Logistics and Technology) and the Commanding General, U.S. Army Materiel Command. Two chemical stockpile disposal facilities in Colorado and Kentucky are managed by the Program Manager for Assembled Chemical Weapons Alternatives, who directly reports to the Office of the Secretary of Defense, in accordance with Public Law 107-248.

In November 2000, the Johnston Atoll Chemical Agent Disposal System completed the destruction of the last munitions stored at the atoll, and closure operations were completed in November 2003. The Tooele Chemical Agent Disposal Facility in Utah has destroyed more than 52 percent of the chemical agents and 87 percent of the munitions stored at Deseret Chemical Depot, Utah.

The Anniston Chemical Agent Disposal Facility in Alabama has destroyed more than 10 percent of the chemical agent and 6 percent of the munitions stored at Anniston Army Depot, including the entire stockpile of nerve agent GB M55 rockets.

The Umatilla Chemical Agent Disposal Facility in Oregon began operations in September 2004 and has destroyed 12 tons of chemical agent. The Aberdeen Chemical Agent Disposal Facility in Maryland has destroyed more than 64 percent of the chemical agent stored at Edgewood Area of Aberdeen Proving Ground, and is scheduled to complete agent destruction in 2005.

Chemical stockpile disposal facilities in Pine Bluff, Arkansas, and Newport, Indiana are scheduled to begin destruction operations in 2005. As of February 2, 2005, the Army has destroyed more than 11,076 tons of chemical agent, some 35.1 percent of the United States' stockpile. The United States continues to comply with all CWC requirements.

The Non-Stockpile Chemical Materiel Project has met all CWC requirements to date and is on track to meet future milestones. More than 83 percent of former chemical weapons production facilities have been destroyed and demolition is ongoing at remaining former production facilities in Newport, Indiana and Pine Bluff, Arkansas. A number of mobile systems are available for assessment and disposal of recovered chemical warfare materiel. These include the Mobile Munitions Assessment System (three units), the Rapid Response System (one unit), the Single Chemical Agent Identification Set Access and Neutralization System (multiple units) and the Explosive Destruction System (three phase 1 units and one phase 2 unit).
