Study on Activity at Samarra since the Beginning of the Crisis (U) Filename:008bk.90d [ (b)(2) ] 28 September 1990 INFORMATION PAPER Subject: Study on Activity at Samarra since the Beginning of the Crisis (U) 1. Purpose. To provide JS-SA with an analysis of the types, of actiVity, trends, and peaks of activity at Iraq's Samarra Chemical Warfare Production Facility. Key Points - Iraq is believed to have produced, filled and stored Chemical agents and munitions in two production cycles between April and September 1990. - Iraq's unitary agents are not pure and decompose, requiring additional agent production and munitions filling in order to maintain an effective chemical warfare (CW) Stockpile. - The first Production/filling cycle is believed to have occurred from April to mid-August 1990. Activity believed to be associated with the production and transport of chemical precursors and chemical warfare agents occurred from April to late July 1990, during which time 600-1,000 MT of nerve agents and mustard are assessed to have been produced -- Chemical munitions filling probably occurred from midJuly to 17 August. -- Trucks and Chemical-related containers appeared near the Probable CW storage bunkers from July to 12 August. At that time, the doors to five of eight Cruciform bunkers were closed for the first time Since January 1990, suggesting the bunkers were filled. - The Second production Cycle appears to have begun in late August and continues as of 28 September - Activity near the probable material Storage area was noted again from late August to 23 September. Liquid transport trucks, perhaps from Habbaniyah II, which may have contained chemical precursor for the production of nerve agent were observed. -- Probable filling activity began 26 September and has continued to 28 September. Periodic cycles of agent production and munitions filling are expected to continue. -- Iraq's unitary agents are unstable with a shelf- life of 4-6 weeks. As the chemical agent breaks down, agent must be produced and munitions filled. - - These activities suggest the Iraqis are maintaining, or perhaps increasing, their munitions stockpile.
