DENVER – The Army wants to change the way in which it destroys a part of its stockpile of old chemical weapons in Colorado, but some people worry that could increase the risk of contamination of the air.
The Army is the eradication of 780,000 shells filled with thick liquid mustard agent at the Pueblo Chemical Depot under an international treaty.
A $4.5 billion plant is supposed to do the work, but officials said this week that they want to buy two detonation chambers for approximately $30 million per to destroy 97,000 problematic shells.
Project manager Greg Mohrman says that the shells probably have more rust contamination than originally expected. That makes it difficult for the plant’s robotic equipment to open them.
State and local permits for the blast rooms are needed before they can be built.
