Program Executive Office, Assembled Chemical Weapons Alternatives. It is a joint activity within the United States Department of Defense responsible for the safe, environmentally sound destruction of the remaining U.S. stockpile of assembled chemical weapons. Established in 2010, it succeeded the Assembled Chemical Weapons Alternatives program to accelerate the demilitarization mission. The office manages the final chemical weapons disposal campaigns at the Blue Grass Army Depot in Kentucky and the Pueblo Chemical Depot in Colorado.

History and background

The office's origins are rooted in the international obligations of the Chemical Weapons Convention, a treaty ratified by the United States Senate in 1997. Prior disposal efforts, managed by the United States Army Chemical Materials Agency, utilized incineration at sites like the Johnston Atoll Chemical Agent Disposal System and the Tooele Chemical Agent Disposal Facility. Due to significant public opposition and congressional mandates, alternative technologies were pursued for the remaining stockpiles in Kentucky and Colorado. This led to the creation of the original Assembled Chemical Weapons Alternatives program. In 2010, to improve oversight and execution, the United States Department of Defense reorganized the effort into the current Program Executive Office structure, placing it under the authority of the Under Secretary of Defense for Acquisition and Sustainment.

Mission and objectives

The primary mission is the complete destruction of the chemical weapons stockpile in compliance with the Chemical Weapons Convention, which set a series of destruction deadlines extended through international agreement. Core objectives include executing destruction operations with an unwavering commitment to the safety of the workforce, the public, and the environment. The office is tasked with employing neutralization-based technologies, rather than incineration, at its two remaining sites. A final, critical objective is the closure of all facilities and remediation of the sites upon completion of the destruction campaigns, thereby eliminating the threat posed by these legacy weapons of mass destruction.

Organization and structure

The program is led by a Program Executive Officer, a senior official within the United States Department of Defense acquisition hierarchy. The headquarters staff at Aberdeen Proving Ground provides overarching program management, contracting, and oversight. The two main operating sites are the Blue Grass Chemical Agent-Destruction Pilot Plant in Richmond, Kentucky, managed by Bechtel National, Inc., and the Pueblo Chemical Agent-Destruction Pilot Plant in Colorado, managed by a team led by Bechtel National, Inc. and Battelle Memorial Institute. Key partners include the United States Army Corps of Engineers, state regulatory agencies like the Colorado Department of Public Health and Environment, and citizen advisory commissions.

Key programs and projects

The flagship projects are the destruction campaigns at the two pilot plants. The Pueblo Chemical Agent-Destruction Pilot Plant uses neutralization followed by biotreatment to destroy its stockpile of mustard agent-filled projectiles. The Blue Grass Chemical Agent-Destruction Pilot Plant employs neutralization followed by supercritical water oxidation to destroy its stockpile of VX and GB munitions. Other critical projects include the ongoing transport and destruction of energetics (bursters and fuzes) and the complex logistics of managing hydrolysate, the secondary waste stream from neutralization. The office also manages the Chemical Stockpile Emergency Preparedness Program in coordination with FEMA to protect surrounding communities.

Challenges and controversies

The program has faced significant technical challenges, including delays and cost overruns associated with designing, constructing, and operating first-of-a-kind destruction facilities. The treatment of hydrolysate has been a persistent technical and regulatory issue. Public skepticism and oversight from entities like the Government Accountability Office and the Congressional Budget Office have been constant. The program operated under the threat of international non-compliance with the Chemical Weapons Convention, requiring diplomatic efforts to secure deadline extensions from the Organisation for the Prohibition of Chemical Weapons. Community concerns, while lessened from earlier incineration debates, have focused on plant safety and schedule reliability.

Future outlook and legacy

The future focus is the successful completion of destruction operations, with the Pueblo Chemical Agent-Destruction Pilot Plant finishing its campaign and the Blue Grass Chemical Agent-Destruction Pilot Plant progressing toward its final milestone. Subsequent closure and dismantlement of the multi-billion-dollar facilities will be a major undertaking. The program's legacy will be the permanent elimination of the last of the U.S. chemical weapons stockpile, fulfilling a decades-long national security and nonproliferation goal. The technological expertise gained in chemical demilitarization may inform future efforts to destroy other hazardous materials, contributing to global security under frameworks like the Organisation for the Prohibition of Chemical Weapons.
