The U.S. Army Chemical Materials Activity (CMA) safely stores and destroyed the Nation's aging chemical weapons formerly stored at eight sites across the United States and on Johnston Atoll, effectively recovers the Nation's chemical warfare materiel and treats it and enhances national security.

The activity's headquarters' management team, as well as scientific, communications and support staff are based at the Edgewood Area of the Aberdeen Proving Ground in Maryland, while other dedicated managers and staff fulfill the activity's mission from weapons storage and disposal sites at locations across the country.


The Project Manager – Chemical Stockpile Elimination managed the safe treatment and disposal of chemical agents and weapons at seven stockpile sites using incineration and neutralization technologies.

Disposal operations using neutralization technology were completed in February 2006 at the Aberdeen Proving Ground, MD, facility - eliminating more than 5 percent of the Nation’s chemical agent inventory. The disposal facility is now closed. The Newport Chemical Depot, IN, facility completed chemical stockpile disposal operations in August 2008 – eliminating 4 percent of the Nation’s chemical agent inventory. The disposal facility and the depot are now closed.

Disposal operations using incineration technology were completed in 2000 at Johnston Island,in the Pacific southwest of Hawaii. This was the first site to complete disposal of all chemical warfare materiel, ridding the Nation of more than 6 percent of its chemical agent inventory. Three other incineration-technology sites have since completed operations. Pine Bluff Arsenal, AR completed disposal operations in November 2010, its stockpile accounted for approximately 12 percent of the Nation’s overall stockpile. Anniston Army Depot, AL, counted for 7 percent of the Nation’s stockpile and completed operations on Sept. 22, 2011. Umatilla Chemical Depot, OR, finished operations on Oct. 25, 2011, eliminating its stockpile that was 12 percent of the Nation’s original stockpile. Deseret Chemical Depot, UT, counted for the largest stockpile, 44 percent, and finished operations on January 21, 2012. Pine Bluff Arsenal, Anniston Army Depot, Umatilla Chemical Depot and Deseret Chemical Depot are currently working on closure activities.

The Non-Stockpile Chemical Materiel Project (NSCMP) leads the Nation in the development and utilization of advance technology to safely eliminate America's remaining non-stockpile chemical materiel in a safe, environmentally sound and cost-effective manner. NSCMP researches and develops treatment options and destruction plans that comply with all federal, state and local regulations and encourage public participation in its activities.

CMA complied with the 1997 Chemical Weapons Convention, an international treaty which the United States and more than 150 other nations have signed as their pledge to rid the world of chemical weapons.

Congress established the Assembled Chemical Weapons Alternatives Program in 1997 to test and demonstrate at least two alternative technologies to the baseline incineration process for the demilitarization of assembled chemical weapons. In Pueblo, CO neutralization followed by biotreatment will be used to destroy the Pueblo stockpile and in Blue Grass, KY neutralization followed by supercritical water oxidation is being implemented. Contract teams at both Colorado and Kentucky are currently designing pilot test facilities which will ultimately lead to the safe destruction of chemical weapons.


CMA is also responsible for safe storage of the Nation's chemical weapon materiels pending its ultimate destruction. CMA manages a National Inventory Control Point and National Maintenance Point to ensure the stockpile is maintained safely during its remaining storage life.

The activity also partners with the Federal Emergency Management Agency to ensure the emergency preparedness of the communities surrounding the depots where stockpiled chemical weapons are stored. The Chemical Stockpile Emergency Preparedness Program works closely with communities adjacent to the Nation's remaining chemical weapons stockpiles. Its mission centers on enhancing emergency response plans and training, and identifying and securing response equipment and warning systems to meet each communities' emergency preparedness needs.
