About 960,000 pounds of GB nerve agent, or about 12 percent of the arsenal's chemical weapons stockpile, have been disposed of since incineration began March 29, 2005, in accordance with an international treaty. The entire process is expected to take five years.
Officials with the Pine Bluff Chemical Activity say the last of the GB nerve agent weapons was destroyed Saturday.
Lt. Col. Casey Scott, commander of the Pine Bluff Chemical Activity, says the world is much safer now that the weapons have been destroyed.
The arsenal housed 12 percent of the nation's chemical weapons stockpile and was the fifth site to begin incineration under the treaty that mandates countries destroy their chemical weapons stockpiles by 2012.
Since March 2005, more than 90,000 rockets and two one-ton containers have been destroyed. Officials say the GB-filled munitions were a priority because they posed the greatest storage risk.
The chemical weapons have been stored at the Pine Bluff Arsenal for more than 60 years. In the disposal process, rockets containing the chemicals are moved from storage to the incinerator. The liquid inside the rockets are burned in one furnace and the metal casing is chopped up and deactivated in another furnace.
