The U.S. Army is back to destroying outdated chemical weapons at a Colorado facility after it was forced to shutdown the plant last year for repairs.
On Wednesday, officials announced the automated $4.5 billion plant began a gradual restart this week.
The plant — located in southern Colorado — is destroying more than 700,000 decades-old shells containing 2,500 tons of liquid mustard gas.
A series of problems, including a leak in the storage tank, forced the plant to close down last September.
The site manager said it could take up to 60 days for the plant to return to full operation.
The U.S. government has agreed to eliminate all its chemical weapons under an international treaty.
