Calhoun County’s last batch of sarin nerve agent is now on deck, waiting to be destroyed.

Workers at the Anniston Chemical Activity, the agency which handles chemical weapons storage at the Anniston Army Depot, delivered the last load of sarin-filled 105 mm projectiles to disposal crews Wednesday.

The shells now are at the Anniston Chemical Agent Disposal Facility (ANCDF), where crews will destroy the weapons and the sarin, also known as GB.

“That means the end of GB disposal is just around the corner,” said Mike Abrams, an Army spokesman for the ANCDF.

In a statement released Wednesday, Anniston Chemical Activity commander Lt. Col. Darryl Briggs highlighted his workers’ safety record in moving the weapons.

“The work accomplished by our ANCA employees has been instrumental in the overall success we have achieved throughout 40 years of safe storage, two-and-a-half years of safe munition movement, and safe disposal operations,” Briggs said.

Wednesday’s delivery was the last of 2,872 trips by storage workers to deliver sarin-filled weapons.

Sarin was roughly 20 percent of the facility’s original chemical stockpile. Once the last of the sarin is gone, workers will spend 17 weeks preparing to destroy weapons filled with the nerve agent VX, to be followed by mustard blister agent.
