This story was published Thu, May 3, 2001 By The Associated Press and the Herald staff HERMISTON - A specially trained chemical operations crew detected a trace
amount of nerve gas inside a storage bunker Wednesday at the U.S. Army's
Umatilla Chemical Depot. The vapor was detected around a ton container, a storage igloo that holds
liquid nerve agent. Depot officials said they believe one of the container's five plugs is
releasing small amounts of the vapor into the bunker. As a precaution, an
air-filtering device is filtering air from the structure. Most of the ton containers on the base are filled with mustard gas, but
there are a few used for storing sarin and Vx, which are nerve agents, said
Mary Binder, depot spokeswoman. Binder said that in the early 1980s, nerve agent from leaking bombs and
rockets was drained and placed in ton containers. Most of the weapons stored in the igloo previously have leaked and were
"overpacked" for additional safety and protection before being
moved there for storage. The bunker is monitored daily. A chemical crew will tighten the plug on the container Thursday to stop
the leak. The leak was the second reported at the depot this year. The first was
detected Feb. 28. The last time the depot reported a leak from a ton container
was in 1993. The depot stores more than 220,000 bombs, rockets and other weapons containing
chemical and nerve agents in 89 storage igloos. The depot houses about 12
percent of the nation's chemical stockpile. Copyright 2002 Tri-City Herald. All rights reserved. This material
