The United States will soon begin to destroy its largest remaining stockpile of chemical-laden artillery shells at the Pueblo Chemical Depot in Southern Colorado, The Associated Press reported. About 2,600 tons of aging mustard agent will be neutralized in March, as part of the country's effort to comply with a 1997 treaty that bans all chemical weapons. Nearly 90 percent of the country's depots in Alabama, Arkansas, Indiana, Maryland, Oregon and Utah that carried the weapons have been destroyed.
