Construction will begin soon on a plant that will destroy mustard gas stored at the Pueblo chemical depot.
Since the 1950's, 26 hundred tons of mustard agent have been stored at the depot. But the aging weapons are, now, obsolete and could become unstable over time.
Senator Wayne Allard says the new facility is critical to the long term safety of the area.
"This is important. We need to get this cleaned up and we need to get it cleaned up as quickly as possible."
The mustard agent will be destroyed in the new plant. They will use a process called neutralization followed by bio-treatment. Hot water will neutralize the chemicals. Then, microbes will eat any remaining by-products.
The plant will be built and operating by 2009. It will be closed and torn down by 2013.
