PUEBLO, COLO. (AP) — Officials say about one-fourth of the mustard agent contained in decades-old shells stored at a Colorado chemical depot has been destroyed.
The Pueblo Chieftain reports the obsolete chemical weapons are being dismantled and destroyed at the Pueblo Chemical Agent-Destruction Pilot Plant.
The acting site project manager, Walton Levi, said in a statement this week that a quarter of the 2,600 tons (about 2,360 metric tons) of mustard agentwas destroyed.
The Pueblo plant began operation in September 2016 and has destroyed 112,400 chemical projectiles.
The facility had a stockpile of 780,000 projectiles.
Officials with the Pentagon's Assembled Chemical Weapons Alternatives plan to bring static detonation chambers to the facility to incinerate problematic rounds.
