Army officials today plan to begin destroying the remaining chemical weapons stored at the Army Depot.

This is the third and final campaign to dispose of chemical weapons stockpiled in Anniston. The first two saw the destruction of different types of nerve agent. All that remains now are weapons armed with less-lethal mustard blister agent.

For local residents, it will be like any typical day, said Army spokesman Mike Abrams. But at the Anniston Chemical Agent Disposal Facility, Westinghouse workers will manually place 4.2-inch mustard-filled mortars on a conveyer system and a robotic system will dismantle it and then send it to large incinerators.

"And we have hundreds of thousands of those to do," Abrams said.

Officials expect to have all mustard weapons disposed of by April 2012. "We still have a ways to go to eliminate the entire Anniston stockpile," he said. "But things are progressing well."

The Army stores chemical-filled munitions at the depot and has been destroying the weapons since August 2003. Since then, officials have destroyed more than 361,000 rockets, artillery shells and landmines, and more than 293,000 gallons of nerve agent. That eliminated 99 percent of the risk that existed for the community, the Army says.

Officials disposed of the last nerve agent weapons on Christmas Eve. Since then, officials have conducted repair work to prepare for the final campaign.
