NRC Urges Better Monitoring Of Stored Arms
NRC Urges Better Monitoring Of Stored Arms

The Army has been monitoring its aging stockpile of chemical
weapons for leaks for 30 years, yet a recent study by the
National Research Council urges improvements to protect the
environment, workers, and adjacent communities. More than 3
million sarin-, VX-, and mustard gas-filled weapons are stored at
eight U.S. sites and are being or will be destroyed.
Three decades of monitoring has resulted in a massive amount of
data, but the Army has mismanaged much of the collected
information, the NRC committee finds. Scarce or missing is
information on the age of leaking munitions and the temperature
at which the weapons are stored. Leaks may increase with
temperature and with aging, the committee warns. It recommends
that the Army "improve its handling of the data and analyze it
for trends in leak developments and other anomalies."
The Army's monitoring program has focused on sarin-filled weapons
that are prone to leak. But the NRC committee cites its concern
for the Army's less vigilant efforts in monitoring leaks of
mustard gas- and VX-filled munitions. Levels of stabilizers in VX
weapons may be dropping to very low levels, leading to increased
leakage rates.
Another hazard the committee cites is the buildup of pressurized
hydrogen in weapons as mustard gas degrades. It calls on the Army
to take steps to minimize this risk.
Risk from ongoing degradation of stored weapons is minor now, but
degradation will only continue, cautions committee Chairman Peter
B. Lederman. So, the retired New Jersey Institute of Technology
professor says, swiftly destroying the weapons "is ultimately the
only effective way to reduce risks to the public."
