All Nerve Agent Projectiles Now Destroyed at Blue Grass Army Depot

Rockets will be the final munitions to be destroyed containing the obsolete chemical warfare agent

The Blue Grass Chemical Agent-Destruction Pilot Plant (BGCAPP) team destroyed the last of the 155mm projectiles containing VX nerve agent May 28.

“There are two important milestones to recognize here,” said Dr. Candace Coyle, BGCAPP site project manager. “This marks not only the completion of the second of five destruction campaigns in Kentucky, but also the destruction of all projectiles containing nerve agent in the U.S. chemical weapons stockpile.”

With the completion of the VX 155mm projectile campaign, BGCAPP teams will now focus on completing destruction of mustard-filled projectiles and preparing for destruction of nerve agent-filled rockets.

Destruction operations of the VX 155mm projectiles began at the Blue Grass Army Depot (BGAD) Jan. 10, 2021. Under the observation of trained operators, automated equipment disassembled nearly 13,000 munitions and drained the chemical agent. The agent was neutralized by mixing it with water and caustic to produce hydrolysate. After the agent was confirmed destroyed, the hydrolysate was pumped to holding tanks to be processed later at an off-site disposal facility. Remaining metal parts from the munitions were decontaminated and recycled.

“The VX projectile campaign marks the second time our team has safely completed a munitions destruction campaign during a pandemic,” said Ron Hink, Bechtel Parsons Blue Grass (BPBG) project manager. “Our experience in safely destroying projectiles puts us on the right path forward to begin safely destroying rockets containing nerve agent later this summer.”

Throughout the campaign, BGCAPP personnel coordinated with the Blue Grass Chemical Activity (BGCA) personnel on transport of the projectiles from storage igloos on the depot to the plant. Part of the organization’s mission is the safe and secure storage of the chemical weapons stockpile.

“The partnership between BGCA’s experienced chemical operations personnel and BGCAPP keeps things running smoothly,” said Lt. Col. Ed Williams, BGCA commander. “BGCA is proud to be a part of this milestone, and we look forward to supporting the next phase of destruction.”

Col. Steve Dorris, BGAD commander, called the achievement a valuable milestone.

“For the first time since the early days of our involvement in the Vietnam War, we can all proudly say that chemical weapon nerve agent projectiles now no longer exist, not only in central Kentucky, but in the entire United States,” he said.

The chemical weapons stockpile at BGAD originally consisted of 523 tons of chemical agent configured in 155mm projectiles containing mustard and VX nerve agent, 8-inch projectiles containing GB nerve agent, and M55 rockets containing GB and VX nerve agent.

In June 2019, the BGCAPP team began destroying the mustard stockpile using the Static Detonation Chamber, an explosive destruction technology. The mustard campaign is more than 85% complete. From January through May 2020, nearly 4,000 8-inch projectiles containing GB nerve agent were destroyed at BGCAPP.

As of May 21, more than 27% of the original 523 tons of chemical agent have been destroyed in Kentucky.

The Program Executive Office, Assembled Chemical Weapons Alternatives is responsible for destroying the remaining U.S. chemical weapons stockpile in Colorado and Kentucky. The organization oversees the contract for design, construction, systemization, operation and closure of BGCAPP with BPBG and subcontractors Amentum, Battelle Memorial Institute and GP Strategies.

“The truly important accomplishment here is that the work was done safely,” said Michael S. Abaie, program executive officer for the Assembled Chemical Weapons Alternatives program. “Your friends and neighbors are the ones getting this job done on behalf of the United States and are critical to this mission. The entire Blue Grass workforce is to be commended for reaching this goal.”

“I am very thankful for the dedicated staff at the Blue Grass Army Depot,” said Reagan Taylor, judge executive, Madison County, Kentucky. “Hitting another milestone in this process is an example of the hard work it took to complete this phase of the mission. I am grateful for the high priority the depot takes in keeping Madison County safe. I’m confident this hard work and determination will continue to the next milestone of destroying these chemical weapons.”

The stockpile sites in Colorado and Kentucky account for the last 10% of what was originally a national stockpile of more than 30,000 tons of chemical weapons. The U.S. Army Chemical Materials Activity destroyed the initial 90%, which was stored at seven other sites across the U.S. and on Johnston Atoll in the Pacific. Chemical weapons destruction in Colorado began in 2015. Both sites are on target to complete destruction of chemical weapons by Dec. 31, 2023.
