OVERVIEW Filename:0135pgv.00d OVERVIEW: - There are at least three biological warfare (BW) production facilities in Iraq and seventeen refrigerated bunkers capable of storing 84 agents/munitions. Anthrax and botulinum toxin are confirmed BW agents which are believed to have been weaponlzed. The Iraqis have shown interest in the development of a number of other infectious agents and toxins for 84 purposes but the status of development is not known. It also is not known what types of munitions have been filled with 84 agent but could include missile warheads, aerial bombs with and without cluster submunitions, the super gun, artillery, and spray and aerosol generating devices. BW agents are likely stored in bulk containers and in munitions as dried powders and/or liquids. The Iraqis have had cultures of the anthrax bacterium (Baciilus anthracis) and the bacterium (Clostridium botulinum) which produces botulinum toxin since early 1986. The necessary equipment for production of the agents has been in place for a longer period. In the interim, significant quantities of these 84 agents, and possibly others, are believed to have been produced. Anthrax spores would Pose the greatest risk to humans of any of the confi rmed or suspect Iraqi 84 agents due to its ability to survive in the environment. Based upon the technical capability of the Iraqis, it is well within their capacity to have produced and stored 1,000 kilograms of dried anthrax spores. This will be used as the amount of agent which could be stored in bulk containers or munitions in any one of the seventeen refrigerated bunkers for the purpose of estimating collateral damage. TECHNICAL ASSESSMENT: The storage bunkers are large with each bunker having a capacity of approximately 440,000 kilograms (7.5 million kilograms collectively for the seventeen bunkers) if all the agent were stored in bulk containers. Assuming that 1,000 kilograms of dried anthrax spores are stored in a bunker in bulk containers, only about 0.25% of the storage capacity would be utilized. If filled munitions are present as well, consequently greater storage space would be used up. In either case, 1,000 kilograms would represent about one million trillion anthrax spores. If 99.99% of these spores were killed or somehow contained in the bunker, this would leave 0.01%, or about 100,000 billion spores for release into the air. This translates into 5-10 billion human lethal doses. Alternatively, if only 100 kilograms of dried anthrax spores were stored and 0.01% released, this would translate into 0.5-1.0 billion human lethal doses. OTHER CONSIDERATIONS: If the storage bunkers are attacked and a plume results, the spores will be carried into the plume to a height depending upon the size of the explosion and any resulting fire. Once in the air, the spores will be carried to a distance depending upon a number of meteorological conditions. Wi nd speed and temperature gradients (i .e. neutral, inversion) would have the most pronounced influence upon dispersal of the aerosol cloud. The prospect for the occurrence and maintenance of neutral or inversion conditions is most likely between sunset and sunrise. Under such conditions and a moderate wind, the cloud would travel tens and possible hundreds of kilometers. More detailed analysis of meteoro1ogical conditions, terrain, and aerosol cloud dynamics are still in progress in order to further define the potential area of contamination. PHYSICAL TARGET VULNERABILITY: Detailed vulnerability studies are ongoing to determine options available to either destroy or contain the BW agents, or to deny access to them.
