The Pueblo Chemical Agent-Destruction Pilot Plant (PCAPP) safely destroyed the chemical munitions stored at the U.S. Army Pueblo Chemical Depot (PCD) in accordance with applicable federal, state and local environmental requirements. The following is a summary of key program partners and their roles in reaching this shared goal.

Program Executive Office, Assembled Chemical Weapons Alternatives (PEO ACWA)

PEO ACWA was established to demonstrate alternatives to the baseline incineration technology for the destruction of assembled chemical weapons. PEO ACWA was responsible for completing stockpile destruction operations at PCD and continues destruction operations at the Blue Grass Army Depot (BGAD) near Richmond, Kentucky, by the Chemical Weapons Convention treaty commitment of Sept. 30, 2023.

Pueblo Chemical Agent-Destruction Pilot Plant (PCAPP)

PCAPP is a state-of-the-art, full-scale pilot facility that safely destroyed the Pueblo chemical weapons stockpile.

U.S. Army Pueblo Chemical Depot (PCD)

The depot is located east of Pueblo, Colorado. It is a 23,000-acre U.S. Army installation that was responsible for the safe and secure storage of the chemical weapons stockpile of mustard agent in Colorado. PCD has been in operation since 1942 and stored chemical agents since the early 1950s.

U.S. Army Chemical Materials Activity (CMA)

CMA manages the U.S. stockpile of chemical weapons, enabling the Army to focus solely on the national security mission. Headquartered at the Edgewood Area of Aberdeen Proving Ground, Maryland, CMA assesses and destroys recovered chemical warfare materiel. CMA maintains safe and secure storage of the Army’s remaining chemical stockpile site via the Blue Grass Chemical Activity at BGAD, Kentucky, until that stockpile is destroyed by PEO ACWA.

Chemical Stockpile Emergency Preparedness Program (CSEPP)

CSEPP enhances the emergency preparedness of Pueblo County, PCD and the state of Colorado through equipment, personnel, training and public awareness. This program involves PCD, the Pueblo County Sheriff’s Office Emergency Services Bureau, the Colorado Department of Public Safety, Division of Homeland Security and Emergency Management (DHSEM), and the Federal Emergency Management Agency (FEMA).

Colorado Department of Public Health and Environment (CDPHE)

The CDPHE mission is to protect public health and the environment. The department is responsible for enforcing the Hazardous Waste Regulations in the state of Colorado and considers the U.S. Army’s permit applications for PCAPP. Representatives of the Hazardous Materials and Waste Management Division actively participate in meetings regarding chemical weapons destruction in Colorado.

Colorado Chemical Demilitarization Citizens’ Advisory Commission (CAC)

In accordance with Public Law 102-484, the CAC serves as a bridge between the community and the government by providing a forum for exchanging information about chemical weapons destruction. The governor of Colorado appoints members of the CAC, including private citizens, who represent the local community. The CAC conducts public meetings to facilitate consistent public participation in the chemical weapons destruction program.
