| Secret
desert project on anthrax

Last year, scientists at a secretly
constructed laboratory in the Nevada desert manufactured simulated anthrax
germs using off-the-shelf technology and over-the-counter equipment - a
project that seems eerily prescient in light of the current germ attacks.
What they discovered is not encouraging:
For about $1.6 million, a small group of microbiologists and engineers
could grow enough anthrax to kill or injure thousands of people without
detection by U.S. law-enforcement or intelligence agencies.
Defense officials said the project
did not take the production process to its final conclusion and "weaponize''
the germ, but two biological weapons experts familiar with the project
say the anthrax germs were in fact finely milled in particles of less than
5 microns - a key step in preparing anthrax for widespread dispersal.
Either way, the project's results
tend to lend credence to arguments that the anthrax germs in the current
attacks may have been produced domestically.
Last week, White House spokesman
Ari Fleischer said the anthrax involved in the letter attacks could have
been produced by a "Ph.D. microbiologist ... in a small, well-equipped
microbiology lab,'' although some bioterrorism experts said that was understating
the complexity of such an effort.
The desert program, parts of which
remain classified, was officially named Biotechnology Activity Characterization
by Unconventional Signatures, or Project BACUS for short. It was run primarily
by the Defense Threat Reduction Agency, which was created by the Defense
Department in 1998 to address biological, chemical and nuclear weapons
proliferation issues.
Beginning in late 1999, scientists
constructed a laboratory in the desert at the old Nevada Test Site, which
had closed seven years earlier after an underground nuclear weapons testing
moratorium went into effect. No germ warfare experts were involved in the
experiment - only microbiologists and engineers with the kind of experience
that might be commonly found in the pharmaceutical or pesticide industry.
Using equipment bought at hardware
stores, through catalogues or from commercial suppliers - pipes, filters,
a fermenter to grow the germs, an electric boiler to maintain the water
supply and to sterilize the fermenter, a milling machine, and a biosafety
box to control air flow - project participants set up a laboratory in an
old recreation hall and barbershop.
Within weeks, they were able to
produce significant quantities of bacillus thuringiensis and bacillus globigii,
two germs that are closely related to anthrax, but are not harmful. For
test purposes, it was effectively the same thing as producing anthrax for
weaponization.
"We were growing simulants, but
a terrorist could easily grow anthrax in a facility like this and produce
enough quantity in covert delivery to kill, say, 10,000 people in a large
city,'' said Jay Davis, the former head of the threat reduction agency
who oversaw the project and is now a physicist at Lawrence Livermore National
Laboratory in California.
Project BACUS did not mill the
germs to particles of less than five microns - the size necessary to cause
inhalation anthrax, the most dangerous form of the disease - or coat the
germ spores with a material to help them stay airborne and keep them from
clumping, Davis said. That would be the normal procedure in a state-sponsored
biological weapons program and which appears to be the case in the current
anthrax attacks.
The reason for not fully weaponizing
the anthrax was that defense officials did not want to violate the 1972
Biological and Toxin Weapons Convention, the international treaty banning
biological weapons production, Davis said.
Project BACUS "was designed so
that if the Russians had found out about it, it would have withstood a
challenge,'' Davis said. "That's why we didn't do the steps (to weaponize
it.) Do you mill it? Do you prepare to disperse it? You can get into a
legalistic argument that with a simulant you wouldn't violate the treaty,
but most of us feel that's too close to the edge.''
However, two biological weapons
experts familiar with the project told Scripps Howard News Service that
the germs were finely milled. Also, the recently released book on biological
weapons, "Germs,'' written by three New York Times reporters, says the
project acquired a milling machine from a company in the Midwest.
Retired Air Force Col. Randall
Larsen, director of the ANSER Institute for Homeland Security and an instructor
on homeland security at the National War College in Washington, recently
showed Vice President Cheney of vial of finely milled, weaponized bacillus
globigii at a recent briefing on bioterrorism.
Asked about the source of the
weaponized germ, Larsen said it was given to him by "someone in government''
who made it "with equipment purchased over the Internet.''
"It could have come from that
(Project BACUS). I just don't know enough. I just can't say if it did or
not,'' Larsen said.
The project also did not attempt
to develop a means to widely disperse anthrax spores - a key hurdle if
terrorists were to try to kill large numbers of people with the bacteria,
Davis said.
"The real question is not the
amount, but how well they disperse it,'' Davis said. "The current anthrax
going through the mail is the perfect example. People talk about grams
killing thousands of people. Maybe a gram went through the mail, but it
only made a few people sick. ... Hypothetically, the same amount that has
caused the problem in Washington, if you had optimally dispersed it over
a football game, would have caused a lot more infection simply because
you would have had more people you could get at better.''
A key finding of the project was
that the simulated anthrax laboratory didn't have any significant "signature''
- a sign that law-enforcement or intelligence agencies could look for to
try to spot terrorists at work.
Sensors were placed around and
away from the facilities. The project looked for similar kinds of things
law-enforcement agencies look for when they are trying to find illegal
drug dealers making methamphetamine - key purchases of materials or equipment
and the presence of certain chemicals, sounds, odors or amounts of heat.
Germ batches were produced in the winter of 1999 and the summer of 2000
to test for differences between seasons.
"What came out of it is that by
the determinations that they were making (using sensors) it didn't have
a significant signature that would send off alarms or surveillance of something
like that,'' said Dr. Craig Smith, a member of the bioterrorism working
group for the Infectious Disease Society of America and a former instructor
at the U.S. Army Medical Research Institute of Infectious Diseases, the
military's lead laboratory for medical aspects of biowarfare defense.
Project BACUS showed that it is
"pretty easy to hide something if you were smart enough to get all the
parts and the pieces and put it together,'' Smith said.
The threat reduction agency went
public with Project BACUS on Sept. 4, exactly one week before the terrorist
attacks on the World Trade Center in New York and the Pentagon.
"We wish we had done it (the project)
sooner, as always,'' Davis said. "You are caught in this dilemma of how
do you invest against relatively rare, high-consequence events. We would
be happiest if this investment had been a waste of money, but that is not
the way it came out.'' |
