Getting chemical weapons destruction back on track

The following article, written by Jonathan B. Tucker, a senior fellow at the James Martin Center for Nonproliferation Studies, and Paul F. Walker, Global Green USA’s Security and Sustainability Program Chairman, originally appeared in the Bulletin of Atomic Scientists on 27 April 2009.

Article Highlights

• If they continue at their current pace, chemical weapon destruction efforts will miss the extended 2017 deadline; the earliest all chemical agents will be destroyed is 2023.
• The U.S. Army should drop proposals to ship some agents and wastes across state lines to existing destruction and processing facilities.
• U.S. officials should also ensure prompt payment of U.S. dues to the Organization for the Prohibition of Chemical Weapons.
One of the many arms-control challenges facing the Obama administration is to revitalize the sagging effort to destroy the vast U.S. stockpile of chemical weapons left over from the Cold War. A new U.S. Army report, to be released in May along with the Pentagon’s 2010 budget request, will likely conclude that without additional funding, the elimination of these obsolete and dangerous weapons could drag on for another 15 years.
U.S. efforts to dispose of its chemical weapons stockpile have been under way for more than two decades, yet as of April 2009 some 12,600 tons (40 percent) of the original 31,500 tons of blister and nerve agents remain to be destroyed and the program continues to lag far behind schedule. President Obama and Congress should act promptly to reverse the additional delays proposed by the Defense Department, which are undermining the credibility of U.S. support for the Chemical Weapons Convention (CWC) and other international arms control agreements. Slowing the destruction process further would also increase the risks to nearby communities from leaking chemical weapons and possible terrorist attacks on the stockpile.
Back in the 1980s, the U.S. Army, facing political opposition to transporting chemical munitions across state lines, decided to build dedicated destruction facilities at each of the eight chemical weapons storage depots scattered across the continental United States, plus one on Johnston Island in the Pacific Ocean. At present, the Army depots in Maryland, Indiana, and Johnston Island have destroyed their stockpiles, while those in Alabama, Arkansas, Oregon, and Utah are still operating. Construction of the last two destruction facilities is just getting under way at Pueblo Chemical Depot in Colorado and Blue Grass Army Depot in Kentucky. Pueblo holds 2,611 tons of mustard gas in mortar and artillery shells, while Blue Grass houses 523 tons of mustard agent in artillery shells, and sarin and VX nerve gas in projectiles and M55 rockets. Both depots plan to use a two-step destruction process involving chemical neutralization of the toxic agents, followed by treatment of the liquid wastes.
In 2006, the Army admitted that because of persistent technical problems and funding shortfalls, it would not finish destroying the entire U.S. chemical weapons stockpile by April 29, 2012, as required by the CWC. Washington’s expected failure to meet the treaty deadline has elicited strong international criticism from several countries, including Iran. (Russia, which inherited a vast stockpile of chemical weapons from the Soviet Union, is also unlikely to complete its destruction process on schedule.) Congress subsequently passed legislation setting a new deadline of December 31, 2017 for completing destruction of the U.S. chemical weapons stockpile. But the high costs of the wars in Iraq and Afghanistan have caused the Pentagon to divert resources away from chemical demilitarization, further slowing its pace. The Army now expects that Pueblo will not finish destroying its chemical weapons until 2020 and that Blue Grass will not complete the task until at least 2023.
To get the U.S. destruction program back on track, the Army should abandon the option, reportedly under consideration, of shipping some or all of the chemical munitions stored at Pueblo and Blue Grass to existing destruction facilities at depots in other states. Current federal legislation bans such transfers, and attempting to change the law would spark a political firestorm.
