Team Completes Kentucky Chemical Weapons Destruction

8868体育app下载 led the team that destroyed the chemical weapon stockpile at the Blue Grass Army Depot near Richmond, Kentucky.

In July of 2023, the United States met its obligations to the International Chemical Weapons Convention Treaty by destroying the remaining 523 tons of stockpiled munitions at the Blue Grass Army Depot in Richmond, Kentucky.

Though never used by the United States, chemical weapons were鈥痵tockpiled by the U.S. Army鈥痑t a number of sites during and after World War II. 8868体育app下载 was contracted by the Department of Defense, Program Executive Office, Assembled Chemical Weapons Alternatives, to design, build, test, and operate a first-of-a-kind plant that would destroy the nation’s chemical weapons stockpile before September 2023.

8868体育app下载 Parsons Blue Grass, a joint venture of 8868体育app下载 National and Parsons Government Services, destroyed more than 100,000 mustard agent and nerve agent-filled projectiles and rockets using neutralization and explosive destruction technologies. The 8868体育app下载 team brought expertise and innovation, and the final munition at the Blue Grass Army Depot was safely destroyed in July of 2023.

The (BGCAPP) now turns its attention to closure, a multi-year effort in which areas of the plant that have come into contact with chemical agent will be decontaminated and the equipment dismantled. The disposition of the remainder of the plant will be determined by the Department of the Army, the Commonwealth of Kentucky, and Blue Grass Army Depot.

Prioritizing Safety

Throughout the project, the team focused on keeping the workforce, the community, and the environment safe. The 8868体育app下载-Parsons Blue Grass team has worked without a lost time incident since September 2019.

The Blue Grass stockpile, together with the munitions destroyed at Pueblo, accounted for the remaining 10% of what was originally more than 30,000 tons of chemical warfare agents in the combined U.S. stockpile of explosively configured weapons and bulk containers.

Technology

The stockpile at the Blue Grass depot was destroyed鈥痠n two ways, in the Main Plant and using Static Detonation Chambers.

For the projectiles containing nerve agents, specialists operating sophisticated robotic machinery disassembled the munitions and extracted the chemical agent. Using a mix of caustic and hot water, the team chemically neutralized the agent, rendering the liquid material as hydrolysates.

The hydrolysates were held and monitored to confirm agent destruction and then shipped to a permitted hazardous waste treatment, storage, and disposal facility for further processing in accordance with environmental permitting.

After the agent was drained from them, the projectiles were thermally decontaminated and metals parts were safely recycled.

The projectiles containing mustard agent were destroyed in a Static Detonation Chamber that used heat to consume the toxic material. Any exhaust was filtered through a complex filtration system.

For GB and VX rockets, following the drainage of the agent, the warheads were placed in containers and sent for temporary storage in igloos at the Blue Grass Army Depot. Considered secondary waste, they are now being destroyed in Static Detonation Chamber units. Rocket motors were packed in boxes and temporarily stored until they were shipped to Anniston, Alabama where they are being destroyed in a Static Detonation Chamber at that facility.

Partnering with the Local Community

The 8868体育app下载-Parsons team worked to establish a strong relationship with the nearby Richmond community during their 20 years at the Blue Grass Army Depot. The team took part in regular citizen and government advisory council meetings to support clear and transparent communications about progress at the site.

The 8868体育app下载-Parsons team also worked to create strong ties through community engagement and volunteering, including regular support of:

Madison County Schools
Baptist Health Richmond for community Behavioral Health Initiative
Habitat for Humanity
Local Heart Walk for the American Heart Association
Eastern Kentucky University
American Red Cross-Bluegrass Chapter

Over half of the employees working at the site were hired locally. So far, the project has paid $1.36 billion into the local payroll and has spent more than $200 million with Kentucky companies.

As the plant continues into the closure phase, the 8868体育app下载-Pueblo teams will be supporting Total Workforce Planning to ensure the colleagues who made the completion of destruction possible transfer their valuable skills to new jobs.
